Get cirrus in the fight against climate change



































FEATHERY cirrus clouds are beautiful, but when it comes to climate change, they are the enemy. Found at high-altitude and made of small ice crystals, they trap heat - so more cirrus means a warmer world. Now it seems that, by destroying cirrus, we could reverse all the warming Earth has experienced so far.












In 2009, David Mitchell of the Desert Research Institute in Reno, Nevada, proposed a radical way to stop climate change: get rid of some cirrus. Now Trude Storelvmo of Yale University and colleagues have used a climate model to test the idea.












Storelvmo added powdered bismuth triiodide into the model's troposphere, the layer of the atmosphere in which these clouds form. Ice crystals grew around these particles and expanded, eventually falling out of the sky, reducing cirrus coverage. Without the particles, the ice crystals remained small and stayed up high for longer.












The technique, done on a global scale, created a powerful cooling effect, enough to counteract the 0.8 °C of warming caused by all the greenhouse gases released by humans (Geophysical Research Letters, DOI: 10.1002/grl.50122).


















But too much bismuth triiodide made the ice crystals shrink, so cirrus clouds lasted longer. "If you get the concentrations wrong, you could get the opposite of what you want," says Storelvmo. And, like other schemes for geoengineering, side effects are likely - changes in the jet stream, say.












Different model assumptions give different "safe" amounts of bismuth triiodide, says Tim Lenton of the University of Exeter, UK. "Do we really know the system well enough to be confident of being in the safe zone?" he asks. "You wouldn't want to touch this until you knew."












Mitchell says seeding would take 140 tonnes of bismuth triiodide every year, which by itself would cost $19 million.

Latin America, Europe back free trade






SANTIAGO: European and Latin American leaders pledged here Saturday to shun protectionism and boost their strategic partnership to foster free trade.

Some 60 countries are represented at the summit between the 27-member European Union and the Community of Latin American and Caribbean States (CELAC).

Set up in Caracas in December 2011 at the behest of Venezuela, CELAC groups all nations from across the Americas except the United States and Canada and aims to boost regional trade and integration.

Chilean President Sebastian Pinera, the two-day summit's host, opened the session with a call for a new "strategic alliance to achieve sustainable development."

And indeed participants unanimously adopted a summit statement extolling their "strategic partnership to achieve sustainable development."

They also reiterated their commitment "to avoid protectionism in all its forms" and to "favour an open and non-discriminatory, ruled-based multilateral trade system."

"We firmly reject all coercive measures of unilateral character with extra-territorial effect that are contrary to international law and the commonly accepted rules of free trade," the statement said.

The leaders also pledged to continue working together "toward a new international financial architecture."

And they backed concrete actions to bolster law enforcement cooperation "to dismantle criminal organizations, all within the full respect of human rights and international law."

There was also support for the convening of a special UN General Assembly session on the global drug problem.

The leaders also gave a nod to "the universality and indivisibility of human rights as laid out in the Universal Declaration of Human Rights."

It was the seventh summit between the two blocs but the first since the creation of CELAC. The two sides agreed to hold the next EU-CELAC summit in Brussels in 2015.

The EU is the biggest outside investor in Latin America, accounting for three percent of direct foreign investment in CELAC or $385 billion in 2010.

EU officials noted that the figure exceeds the combined investment in China, Russia and India.

"We need a strong political commitment to rein in protectionism and promote liberalization," European Commission President Jose Manuel Barroso told a meeting of business chiefs leaders shortly before the political summit's opening.

Powerful German Chancellor Angela Merkel, whom the Chilean press has dubbed "Europe's boss," called for "cooperation without barriers to trade."

"The dynamic development of this entire region shows that we, within the EU, must strive to ensure we are not left behind, to improve our competitiveness, reduce our debt. We cannot live on the backs of future generations," she added.

The Europeans are particularly keen on securing the speedy conclusion of a free trade pact between the EU and the South American trading bloc Mercosur.

Negotiations have so far stumbled over differences on agriculture -- notably Europe's subsidies to its farmers, which undermine Latin America's efforts to sell its own products.

Argentine President Cristina Kirchner, who has taken some protectionist measures, said that the EU-Mercosur negotiations, launched in 2004, must restart on a "new basis" that can clear the way for a deal.

"The negotiations with the EU cannot be based on decisions made in 2004. We need new premises, first among all Mercosur members, not just between Brazil and Argentina," she said after a bilateral session with Rousseff.

Kirchner suggested establishing an ad hoc Mercosur panel to come up with new proposals and make a new offer to the EU later this year.

Meanwhile, a Venezuelan minister said here that President Hugo Chavez has beaten a severe respiratory infection that occurred after his latest cancer surgery in Cuba.

"The respiratory infection has been overcome, although there still is some degree of breathing difficulty that is being treated appropriately," Communications Minister Ernesto Villegas said on the sidelines of a EU-CELAC summit.

Chavez, who had surgery on December 12, has not been seen in public since he left Caracas for surgery at a hospital in Cuba.

Monday, the 33 CELAC leaders will hold their own summit here, with Cuba taking over chairmanship from Chile for one year. They are hoping to overcome ideological and economic differences to foster greater regional integration.

The meeting will seal Cuba's full regional reintegration and mark a major diplomatic coup for 81-year-old President Raul Castro. Cuba, the only non-democratic Communist-ruled country in the Americas, has been under a US economic embargo since 1962.

STORY HIGHLIGHTS


  • NEW: United States agrees to conduct aerial refueling missions, to transport troops

  • Malian and French forces recapture the city of Gao, a stronghold of the Islamic militants

  • The Malian offensive is backed by French forces




(CNN) -- The United States is intensifying its involvement in Mali, where local and French forces are battling Islamic militants.


It will support the French military by conducting aerial refueling missions, according to the Pentagon, which released a short statement Saturday following a call between Defense Secretary Leon Panetta and French Defense Minister Jean-Yves Le Drian.


"The leaders also discussed plans for the United States to transport troops from African nations, including Chad and Togo, to support the international effort in Mali. Secretary Panetta and Minister Le Drian resolved to remain in close contact as aggressive operations against terrorist networks in Mali are ongoing," it read.


U.S. policy prohibits direct military aid to Mali because the fledgling government is the result of a coup. No support can go to the Malian military directly until leaders are chosen through an election.








But the United States is supporting the effort with intelligence and airlift support.


So far, the U.S. Air Force has flown at least seven C-17 cargo missions into Mali, carrying 200 passengers, mainly French troops, and 168 tons of equipment, according to Maj. Robert Firman, a Pentagon spokesman.


The uptick in U.S. involvement comes as Malian forces loosened the grip that Islamist militants' hold in the country's north with the retaking of the city of Gao.


With the support of French forces, the Malians entered and took control of Gao, which for months had been a militant stronghold, the French defense ministry said.


The advance was made in stages, with forces taking Gao's airport and the main bridge leading to town before entering the rest of the city.


"Jihadist terrorists, who have fought Malian and French armies, have seen their mobile and logistical capabilities reduced," the ministry said in a news release.


The quickening advance of the government forces has brought them to the heart of the territory held by the militants.


Broken limbs, torn lives in northern Mali


The Islamic extremists carved out a large haven in northern Mali last year, taking advantage of a chaotic situation after a military coup by the separatist party MNLA. The militants banned music, smoking, drinking and watching sports on television. They also destroyed historic tombs and shrines.


The takeover stoked fear among global security experts that Mali could become a new hub for terrorism.


Refugees tell harrowing stories of life under the Islamist militants.


But the French-based International Federation for Human Rights said it is "very alarmed" by reports that Malian soldiers are themselves carrying out extrajudicial killings and abuses as they counterstrike.


The United Nations' refugee agency, UNHCR, has called for an increase in international aid for the hundreds of thousands of people who have been displaced by the fighting in the country.


More signs al Qaeda in Mali orchestrated Algeria attack


More than 150,000 refugees have fled Mali into neighboring countries, and another 230,000 are displaced inside Mali, the agency said.


The military's advance into Gao may shed more light on the conditions that residents there have faced. According to the U.N. agency, one former resident told of a hospital stripped of medicine by the armed militants and filling with bodies.


As the Malian troops advance, some other countries in the region are joining the French force aiding them. Between 700 and 800 African troops from Benin, Nigeria, Togo and Burkina Faso have arrived, U.S. State Department spokeswoman Victoria Nuland said Friday, and a number of Senegalese troops and up to 2,000 from Chad are on the way.


France has 2,150 soldiers on Malian soil, with 1,000 more troops supporting the operation from elsewhere.


French involvement in the conflict began on January 11, the day after militants said they had seized the city of Konna, east of Diabaly in central Mali, and were poised to advance south toward Bamako, the capital.


Until 1960, Mali had been under French control.


The MNLA, made up of ethnic Tuareg rebels, staged their coup against Mali's central government after returning to Mali well-armed from fighting for late Libyan leader Moammar Gadhafi.

1 officer killed, 2 wounded near La. casino

Updated 8:50 PM ET

NEW ORLEANS Police on Saturday arrested a man suspected of fatally shooting a police officer and critically wounding two sheriff's deputies after allegedly setting fire to a mobile home in south Louisiana, where an elderly man's body was found.

A Chitimacha tribal officer was pronounced dead at the scene of the shootings in Charenton, while two St. Mary Parish sheriff's deputies were critically wounded and taken to local hospitals, said Louisiana State Police Trooper Stephen Hammons.

Hammons said the officers were responding to a report of an armed man walking down a road near the Cypress Bayou Casino when Wilbert Thibodeaux, 48, of Charenton allegedly shot them.

"Thibodeaux fired at the Chitimacha Officer, fatally wounding him," state police said in a news release. "As two St. Mary Deputies, who were in the same car, arrived at the scene Thibodeaux fired multiple shots hitting the deputies. During the encounter, Thibodeaux was shot."

Investigators found the burned remains of a man after extinguishing a fire at a mobile home that Thibodeaux is suspected of setting before the officers confronted him, Hammons said.

Police identified the deceased man in the mobile home as Eddie Lyons, 78, of Charenton. "Detectives suspect Lyons was shot by Thibodeaux before the fire," state police said in a news release.

Thibodeaux was treated at a hospital for a gunshot wound that wasn't considered life-threatening and released, according to Hammons, who said investigators were questioning him Saturday evening. Charges against him are pending.

The state Fire Marshal's office is investigating the fire.

"Today is a difficult day for our partners in St. Mary Parish," Col. Mike Edmonson, the State Police superintendent, said in a statement. "My thoughts and prayers are with the deputies and the officer's families tonight. I know the coming days and weeks will be difficult ones for the men and women of the Chitimacha Police Department and the St. Mary Parish Sheriff's Office. We will assist their agencies in any way we can during these trying times."

The casino is run by the Chitimacha Tribe of Louisiana and is less than a quarter-mile from the scene of the shootings. Hammons said the shootings occurred near but not on tribal land.

"Everybody is just in shock. It's small-town America," said Jacqueline Junca, the tribe's secretary and treasurer.

Police didn't immediately release the names of the officers. Authorities said they will do so at a Monday news conference.

Tribe councilman Toby Darden said the slain officer was married and had two grown children, but he declined to give his name.

"He's a real great guy. Extremely dedicated to his job. Very brave," Darden said.

He was one of seven full-time officers who patrol a 260-acre reservation that has roughly 150 homes, a grocery store, a small school and government offices.

"Everybody knows the officers personally," Darden said. "It's devastating."

Junca said the tribe has around 1,200 members, roughly half of whom live on the reservation.

Access to and from the casino was restricted for roughly 90 minutes as a precautionary measure while police responded to the shooting, said casino spokeswoman Nancy Herrington. Charenton is located about 45 miles southeast of Lafayette.

"We are very much in business and have been," Herrington said later Saturday. "We have events tonight. All of those are taking place."

A spokeswoman for the sheriff's office and a tribal police dispatcher referred questions about the shootings to the State Police.

"We've got a lot of unanswered questions," State Police Capt. Doug Cain said.

One of the injured deputies was taken to a hospital in New Orleans and the other was taken to a Lafayette hospital. Both were listed in critical but stable condition Saturday evening, Hammons said.

Newtown Families March for Gun Control in DC


Jan 26, 2013 4:59pm







gty gun control march washington jt 130126 wblog Newtown Victims Families Join Gun Control Activists on DC March

(YURI GRIPAS/AFP/Getty Images)


WASHINGTON, D.C. — Near-freezing temperatures didn’t stop several thousand gun-control activists from bearing their pickets today, carrying signs emblazoned with “Ban Assault Weapons Now” and the names of gun violence victims in a demonstration organized as a response to the mass shooting in Newtown, Conn. last month.


Walking in silence, the demonstrators trudged between Capitol Hill and the Washington Monument over a thin layer of melting snow. They were joined by politicians and some families of the Newtown victims.


March organizer Shannon Watts said the event was for the “families who lost the lights of their lives in Newtown, daughters and sons, wives and mothers, grandchildren, sisters and brothers gone in an unfathomable instant.”


“Let’s stand together and use our voices, use our votes to let legislators know that we won’t stand down until they enact common sense gun control laws that will keep our children out of the line of fire,” she told demonstrators.


Watts founded One Million Moms for Gun Control after the killing of 20 first graders and six adults at the Sandy Hook Elementary School in Newtown in December. In a profile with the New York Times, Watts said her 12-year-old son had suffered panic attacks after learning of last summer’s Aurora, Colo., theater shooting, leaving her at an impasse over how to talk to him about the latest tragedy.


Also among the speakers was a survivor of the 2007 Virginia Tech massacre, Collin Goddard.


“We need to challenge any politician who thinks it’s easier to ask an elementary school teacher to stand up to a gunman with an AR-15 than it is to ask them to stand up to a gun lobbyist with a checkbook,” he said.


The demonstration comes amid a push by progressive lawmakers to enact stricter gun control measures as a response to the trend of recent mass killings, although any hypothetical bill would likely face strong opposition in Congress.


Rep. Chris Van Hollen, D-Md., was among the demonstrators today.


“The idea that people need high-capacity magazines that can fire 30, 50, 100 rounds has no place in a civilized society,” he said. “Between the time we’re gathered here right now and this time of day tomorrow, across America, 282 Americans will have been shot.”


The congressman was quoting statistics compiled by the Brady Campaign to Stop Gun Violence.


INFOGRAPHIC: Guns by the Numbers


Last week President Obama proposed a sweeping overhaul of federal measures regulating gun ownership, including a universal background check system for sales, banning assault weapons,  and curbing the amount of ammunition available in weapon clips.


An ABC News/Washington Post poll released Thursday found 53 percent of Americans viewed Obama’s gun control plan favorably, 41 percent unfavorably. The division was visible today, as a handful of gun-rights advocates also turned out on the National Mall to protest what they believe would be infringements on their Second Amendment liberties.

Obama, Hollande hold phone talks on Mali offensive






WASHINGTON: US President Barack Obama voiced support Friday for France's military intervention in Mali and vowed to work with French counterpart Francois Hollande to tackle extremism across North Africa.

The two presidents discussed other "shared security concerns," including Algeria, Libya and Syria, during telephone talks, the White House said in a statement.

"The president expressed his support for France's leadership of the international community's efforts to deny terrorists a safe haven in Mali," it added.

In condemning a deadly hostage-taking operation by militants in Algeria last week, the two leaders "affirmed their mutual commitment to countering terrorism more broadly in North Africa," according to the statement.

Preliminary estimates from the Algerian authorities say 37 foreign hostages and 29 kidnappers died in an attack at the In Amenas gas field and in the military operation that followed.

Hollande also thanked Obama for his "significant support" of the effort in Mali, the White House said.

The US Air Force has deployed C-17 cargo planes to carry French troops and equipment to northern Mali, where they are trying to help flush out radical extremist fighters.

The United States also was providing intelligence to France, drawing on its network of satellites and surveillance drones.

Paris has asked Washington to help with refueling its warplanes taking part in the fight against militant fighters in Mali, but Obama's administration has yet to approve the request.

Obama and Hollande also "emphasized the need to rapidly establish" both an African-led military force in Mali and a "political roadmap that will lead to elections and restoration of democratic governance," the White House said.

The pair "condemned last week's terrorist act in Algeria," and "affirmed their mutual commitment to countering terrorism more broadly in North Africa."

Turning to Libya, in the wake of an uprising that toppled dictator Muammar Gaddafi in 2011, the two presidents "noted the importance of sustained assistance to Libya as it works to build effective security sector institutions," the statement added.

Hollande and Obama also spoke about Syria, "expressing their strong concern about the humanitarian crisis affecting not just Syria but also neighboring countries and reiterating their commitment to assisting the Syrian people achieve political transition to a post-Assad Syria," the statement said.

Syria's civil war has already claimed the lives of more than 60,000 people since March 2011, according to the United Nations, which has predicted that the number of Syrian refugees in neighboring countries will double to 1.1 million by June if the conflict does not end.

STORY HIGHLIGHTS


  • Burt Reynolds went to a hospital after developing flu symptoms, his representative says

  • He was dehydrated and moved to intensive care, the representative Erik Kritzer says

  • "He is doing better at this time," Kritzer says Friday afternoon




(CNN) -- Actor Burt Reynolds is in intensive care in a Florida hospital, where he went for treatment of flu symptoms, one of his representatives said Friday.


Reynolds was dehydrated when he went to the hospital, and was eventually transferred to its intensive care unit, his representative Erik Kritzer told CNN.


Kritzer declined to divulge what hospital the actor was in, saying, "He would like that (kept) private."


"He is doing better at this time," Kritzer said late Friday afternoon of the 76-year-old actor. "We expect, as soon as he gets more fluids, he will be back in a regular room."


Born in southern Georgia, Reynolds and his family moved to Michigan and eventually to southeastern Florida, according to his profile on the website of the Florida Artist Hall of Fame, in which he was inducted in 1993. At Palm Beach High School, he first made a name for himself as a football star and earned an athletic scholarship to Florida State University.


When injuries derailed his promising athletic career, Reynolds turned to acting. He scored small parts in the late 1950s, then broke through a few years later in the role of Quint on the TV series "Gunsmoke."


His career took another leap with the 1972 release of "Deliverance," in which he played an Atlanta businessman exploring the remote north Georgia wilderness with friends. "The Longest Yard" came out two years later, starring Reynolds as an ex-football player who lands in prison.


Get the latest update on the flu


These roles earned Reynolds' fame and box office mojo, all while he gained the reputation as a ladies man connected with some of Hollywood's most eligible actresses.


His charismatic notoriety soared through the late 1970s and into the 1980s, during which he spearheaded the "Smokey and the Bandit" and "Cannonball Run" movie franchises. He earned a People's Choice Award in 1979, 1982 and 1983 as all-around male entertainer of the year, and was picked as favorite motion picture actor on that show in 1979, 1980, 1982, 1983 and 1984.


While his popularity waned relatively, Reynolds continued to score movie and TV roles into the 1990s. That included on "Evening Shade," where he earned an Emmy in 1991 playing Wood Newton -- once again, a former football player.


His lone Oscar nomination came in 1998, in the best supporting actor category, for his portrayal of pornographic film producer Jack Horner in the film "Boogie Nights."


Aside from his acting, Reynolds cultivated a prominent public profile through TV commercials, public appearances and more. He also developed a reputation as a philanthropist, especially in his home state of Florida, where he helped found the Burt Reynolds Institute for Film and Threatre.

Notre Dame president defends handling of Te'o case

SOUTH BEND, Ind. Top administrators at Notre Dame decided within hours of hearing about the Manti Te'o dead girlfriend hoax that it did not involve a crime and within two days had concluded there was no NCAA violation, according to a letter sent by the university president to board of trustee members on Friday.

The Rev. John Jenkins told trustees that despite "the unrelenting scrutiny of hundreds of journalists and countless others — and repeated attempts by some to create a different impression- no facts relating to the hoax have been at odds with what Manti told us" on Dec. 27-28.

The letter was obtained Friday by The Associated Press from a university official who provided it on condition of anonymity because the private school's internal workings are confidential.

The eight-page document, including a four-page letter from Jenkins and a four-page outline of how Notre Dame handled the hoax, is both a defense and an explanation of the school's actions.

"We did our best to get to the truth in extraordinary circumstances, be good stewards of the interests of the university and its good name and — as we do in all things — to make the well-being of our students one of our very highest priorities," Jenkins concluded in his letter.

Some of the timeline Notre Dame outlined is well known, including that its star linebacker disclosed the scam to his coaches the day after Christmas and it remained unknown to the public until Deadspin.com broke the story on Jan. 16, long after the Fighting Irish lost the BCS championship to Alabama on Jan. 7.

Jenkins wrote that Notre Dame officials talked in the hours after hearing from Te'o on Dec. 26 and agreed there was no indication of a crime or student conduct code violation. Athletic director Jack Swarbrick spoke with Te'o the next day, and on Dec. 28 the school concluded there were no indications of an NCAA rules violation, which could have put Notre Dame's 12-0 regular season in jeopardy.

The school then made moves to find out who was behind the hoax, thereby protecting Te'o and itself.

"For the first couple of days after receiving the news from Manti, there was considerable confusion and we simply did not know what there was to disclose," Jenkins wrote.

Manti Te'o




On Jan. 2, after several days of internal discussion and a week after Te'o's disclosure, Notre Dame retained Stroz Friedberg, a New York computer forensics firm to investigate the case and whether any other football players had been targeted. The firm did not return phone or email messages left Friday.

Notre Dame officials believed Te'o's girlfriend — whether alive or dead — was at least a real person until the next day, when Stroz Friedberg said it could not find any evidence that Kekua or most of her relatives ever existed. And by Jan. 4, two days after hiring Stroz Friedberg, Notre Dame officials concluded Te'o was the victim of the hoax, there was no threat to the school and the private investigation was suspended.

"We concluded that this matter was personal to Manti," Jenkins wrote, deciding it was up to Te'o to disclose, especially after he signed with Creative Artists Agency on the day after the BCS game.

'Hot' Guns Fueling Crime, US Study Says













Christmas is the one day of the year that Wal-Mart is closed, but for a group of four New Mexico burglars, it was the perfect time to stop in for some firearms.


Video surveillance cameras caught the masked burglars red-handed, stealing rifle after rifle. Police arrested the four men, and were able to recover the guns. But all too often, stolen weapons end up in the hands of criminals.


The New Mexico caper is part of a flood of gun thefts nationwide. And it's not only commercial gun dealers vulnerable to theft.


Guns are a top target for home burglars looking for something they can easily sell on the street.


An estimated 230,000 guns per year are stolen in home burglaries and property crimes, according to a study by the Department of Justice.


"Any burglar that goes in a house and finds guns, their eyes are going to light up," says former ATF Assistant Director Mike Bouchard. "That's the first thing they're going to take."


The statistics for commercial thefts show that nearly 25,000 guns per year are lost or stolen from gun dealers.


According to the Bureau of Alcohol Tobacco and Firearms (ATF), more than 4,000 gun stores and retailers have been targeted in the last three years, with 74,000 guns reported stolen or lost. And criminals will use any method possible to get their hands on some weapons, either for their own use, or to sell on the black market.

Recently, thieves have taken to using a stolen vehicle to ram down the front doors of a gun store. In North Charleston, S.C., for example, burglars smashed a stolen truck right through Guns and Gold Trading Post, stealing $4,500 worth of guns before making a quick getaway.


"Gun stores are like candy stores for criminals," says Mike Bouchard.


2012 was a record year for gun sales, with more than 19.5 million background checks run for gun purchases, up almost 20% from the previous year. But while legitimate sales skyrocket, huge numbers of illegal guns are hitting the streets.


According to the Justice Department, more than 1.4 million guns were stolen or lost between 2005 and 2010.


Former ATF Assistant Director Bouchard says crooks have easy access to cheap stolen guns on the street.


"If you talk to any criminal, they can find a gun within an hour or two. Cheaper guns that were stolen can be sold for $50. On the street, a typical good handgun will run you $200 to $300," Bouchard said.


Some thieves have even targeted gun shipments, stealing the weapons before they get to market.


Last November, for example, a rogue truck driver allegedly stole a shipment of 111 guns he was supposed to deliver from the Smith and Wesson factory in Springfield, Mass.


When police caught him, they recovered 28 of the stolen guns, but some had already been used in crimes.


When police arrested the alleged stick-up robber known as the Black Jacket Bandit, they found one of the stolen guns was allegedly used by him in a convenience store robbery within weeks of the delivery heist.


In November, more than 100 powerful AK-47s were stolen from a rail yard in Atlanta. The guns were in a box car containing more than 1,000 guns being shipped from an overseas manufacturer to a major U.S. distributor, authorities say.


A few of the weapons have been recovered, but police are deeply concerned about having scores of new assault rifles falling into the wrong hands.


Given all the gun thefts, police say it is critical for gun owners to secure their weapons in gun safes or locked cases. And authorities are urging gun retailers to fortify their buildings, to try to prevent "smash and grab" type robberies.

Shrinking proton puzzle persists in new measurement



































A puzzle at the heart of the atom refuses to go away. The most precise measurement yet of the proton's radius confirms that it sometimes seems smaller than the laws of physics demand – an issue that has been hotly debated for two years.












The latest finding deepens the need for exotic physics, or some other explanation, to account for the inconsistency. "If we were in a hole before, the hole is deeper now," says Gerald Miller of the University of Washington in Seattle, who was not involved in the new measurement.












The saga of the proton radius began in 2010, when a group led by Randolf Pohl at the Max Planck Institute of Quantum Optics in Garching, Germany, determined the width of the fuzzy ball of positive charge – and found it was smaller than had been assumed.












Previous teams had inferred the proton's radius, which is impossible to measure directly, by studying how electrons and protons interact. One method uses the simplest atom, hydrogen, which consists of one electron and one proton. A quirk of quantum mechanics says that an electron in an atom can only orbit its proton at certain distances, corresponding to different energy levels. The electron can jump between levels if it absorbs or releases energy in the form of a photon of light.











Ball of charge













By measuring the energy of photons emitted by an excited hydrogen atom, physicists can figure out how far apart the energy levels are, and thus the distances of the permitted electron orbits. A theory called quantum electrodynamics then allows them to calculate how far the proton's ball of charge must extend to keep the electrons at those distances.












This method gave a charge radius for the proton that was about 0.877 femtometres, less than a trillionth of a millimetre.












Pohl and colleagues used a novel method. They created an exotic version of hydrogen that replaces the electron with a muon, a particle that has the same charge as the electron but is 200 times heavier. Its extra bulk makes it more sensitive to the proton's size, meaning radius measurements based on muons are orders of magnitude more precise.












The new method didn't just make the measurements more precise. It also changed them: the muonic hydrogen gave a radius of 0.8418 femtometres, 4 per cent less than before.











Scandalous result












That might not sound like much, but in the world of particle physics, where theory and experiment can agree to parts in a billion, it was scandalous. A lively discussion sprang up, with some physicists claiming problems with Pohl's experiments and interpretations, and others suggesting gaps in the standard model of particle physics.













Pohl and colleagues have now repeated their experiment. The measurement of the radius is now even more precise than in 2010 – and it is still 4 per cent smaller than the value from hydrogen-based experiments.












Pohl reckons that there are three likely explanations. His experiment could have errors, although the confirmation makes that less likely. Alternatively, the electron experiments could be off. "This would be the most boring possibility," says Pohl.












The third, and most exciting, possibility is that muons do not interact with protons in the same way as electrons. In other words, the proton's apparent radius changes a little bit depending on which particle it is interacting with.












If true, that might require the existence of unknown particles that alter the way the muon interacts with the proton. Those particles could, in turn, solve some of the problems with the standard model of particle physics. They could, for instance, provide a candidate for dark matter, the mysterious stuff that makes up more than 80 per cent of the mass in the universe.











Monumental idea













Miller, Pohl and Ron Gilman of Rutgers University in Piscataway, New Jersey helped organise a workshop with 50 proton experts in Trento, Italy, last October to hash out the details of the problem – and arrived at a verdict of sorts. "Because the muon experiments seem to be so solid, the most popular answers were that there's some beyond-the-standard-model physics differentiating between muon and electron, which would be very important," Gilman says.












"That would be monumental, truly," Miller says.












But Miller also has a less radical suggestion, which could reconcile all the measurements without invoking new particles. According to quantum electrodynamics, two charged particles can interact with each other by exchanging a photon – it's as if they spontaneously create a basketball and throw it between them, he says.












The equations also allow for a more complicated interaction where the particles create two balls, and juggle them. Until now this type of interaction was considered too rare to be important, but Miller reckons that the muon's greater mass could make it a better juggler. That would strengthen the proton's interaction with it and make the proton look smaller to the muon without requiring any new physics.












All these ideas will be up for review in a few years' time when new experiments, including shooting muons at protons to see how they scatter and building muonic helium atoms to measure their energy levels, are completed.












"It's quite likely that through other experiments, in two to three years we might get an end to this," Miller says. "It shouldn't take forever."

Australians warned to leave Benghazi immediately






SYDNEY: Australia on Friday joined three European nations in urging its citizens to leave the Libyan city of Benghazi due to a "specific, imminent threat to Westerners" linked to French action in Mali.

The advice followed similar warnings from governments in Britain, Germany and the Netherlands, which sparked an angry response from Libya's government. Tripoli said there was "no new intelligence" to justify such concerns.

But Australia's department of foreign affairs said: "We are aware of a specific, imminent threat to Westerners in Benghazi. All Australians in Benghazi should leave immediately.

"There is a risk of retaliatory attacks against Western targets in Libya following the French intervention in the conflict in Mali in January 2013," it said in an updated travel advice.

"A number of militant groups are known to operate in Libya and some may seek to target Western interests."

Only two Australians are registered as being in Benghazi and just 22 in Libya, said the department.

The alert came after US Secretary of State Hillary Clinton testified to Congress this week about the September attack on the US diplomatic mission in Benghazi that killed four Americans, including the ambassador to Libya.

It also comes as French troops battle Al-Qaeda-linked militants in Mali, amid rising concern about Islamist extremism across north Africa after last week's bloody attack on the In Amenas gas plant in Algeria.

STORY HIGHLIGHTS


  • NEW: U.S. places sanctions on Korean financial entities

  • The U.S. secretary of defense says predicting a North Korean test is difficult

  • Pyongyang says it plans a new nuclear test and further long-range rocket launches

  • North Korea is upset by a recent U.N. Security Council resolution, an analyst says




Seoul, South Korea (CNN) -- North Korea said Thursday that it plans to carry out a new nuclear test and more long-range rocket launches, all of which it said are a part of a new phase of confrontation with the United States.


The North's National Defense Commission said the moves would feed into an "upcoming all-out action" that would target the United States, "the sworn enemy of the Korean people."


Carried by the state media, the comments are the latest defiant flourish from the reclusive North Korean regime, whose young leader, Kim Jong Un, has upheld his father's policy of pursuing a military deterrent and shrugging off international pressure.


U.S. Secretary of Defense Leon Panetta said Thursday there are no "outward indications" that North Korea is about to conduct a nuclear test, but he admitted it would be hard to determine that in advance.


"They have the capability, frankly, to conduct these tests in a way that makes it very difficult to determine whether or not they are doing it," he said in a Pentagon press conference.


"We are very concerned with North Korea's continuing provocative behavior," he said, but he added that the United States is "fully prepared" to deal with any provocations.


Read more: U.N. Security Council slams North Korea, expands sanctions


North Korea's statement prompted France and Great Britain to express exasperation with the secretive regime.


Britain's mission to the United Nations called on North Korean leaders to "refrain from further provocation." France said it "deplores" North Korea's statement, telling its leaders that they need not to threaten, but instead to work toward dismantling their nuclear and missile programs.


In addition to Panetta's statement, the United States responded by adding sanctions against more bank officials and a business linked to the regime's nuclear weapons program.


The Treasury Department announcement targets two Beijing-based representatives of Tanchon Commercial Bank and a company -- Leader (Hong Kong) International Trading Limited -- that the U.S. government says shipped machinery and equipment in support of North Korea's nuclear program.


The organizations are "part of the web of banks, front companies and government agencies that support North Korea's continued proliferation activities," said Under Secretary for Terrorism and Financial Intelligence David S. Cohen.


"By continuing to expose these entities, and the individuals who assist them, we degrade North Korea's ability to use the international financial system for its illicit purposes," he said.


North Korea's statement followed a U.N. Security Council resolution approved Tuesday that the United States pushed for, condemning a recent rocket launch by North Korea and expanding existing sanctions.

The statement "should have been the expected outcome" from the U.N. decision, said Daniel Pinkston, senior analyst for the International Crisis Group covering Northeast Asia.


"I think they are completely outraged and insulted by it," he said.

North Korea, which often issues bellicose statements in its state media, said Thursday that it rejects all Security Council resolutions concerning it, describing the most recent resolution as "the most dangerous phase of the hostile policy" toward it.

Analyst: Threat meant as a deterrence


The threats toward the United States, a constant theme in the North's propaganda, have more to do with deterrence than a desire for full conflict, Pinkston said.


"I don't believe they have the capability, the intention or the will to invade or destroy the United States," he said. "They wish to deter interference from the U.S. or any outside powers."


Read more: North Korea's rocket launches cost $1.3 billion


North Korea's successful rocket launch last month nonetheless changed the strategic calculations for the United States, showing that the North's missile program is advancing despite an array of heavy sanctions imposed on it.


Analysts say it still has a lot of work to do to master the technology necessary to mount a nuclear warhead on a missile or accurately target it.


At the same time, Pyongyang has been hinting for a while that a new nuclear test could be in the cards.


Read more: South Korean officials: North Korean rocket could hit U.S. mainland


Just before the North sent out its latest hostile statement Thursday, a U.S. State Department official was telling reporters in Seoul that Washington hoped Pyongyang wouldn't go ahead.


"We think that that would be a mistake, obviously," said Glyn Davies, the U.S. special envoy on North Korea. "We call on North Korea, as does the entire international community, not to engage in any further provocations."


North Korea has carried out two previous nuclear tests, in 2006 and 2009, both of which were condemned by the United Nations.


Read more: Huge crowds gather in North Korean capital to celebrate rocket launch


Pyongyang didn't say Thursday when exactly it would carry out a third test, but it could happen "at any time," according to Pinkston.


He said it is hard for anybody outside the North Korean nuclear sector to know if the country is technically ready to carry out the test, but that politically, "it seems an appropriate time."


Demands unlikely to sway North


South Korean defense officials said last year that they believed the North was in a position to carry out a new test whenever leaders in Pyongyang gave the green light.


North Korea's nuclear program is "an element of threat to peace not only for Northeast Asia but also for the world," Park Soo-jin, deputy spokeswoman for the South Korean Unification Ministry, said Thursday.


"North Korea should immediately stop its nuclear test and other provocation and should choose a different path by cooperating with the international community," Park said.


That appears unlikely at this stage, though.


After a failed long-range rocket launch in April, North Korea ignored international condemnation and carried out a second attempt last month. That one succeeded in putting a satellite in orbit, Pyongyang's stated objective.


But the launch was widely considered to be a test of ballistic missile technology. And it remains unclear if the satellite, which the North insists is for peaceful purposes, is functional.


Both North Korea's previous nuclear tests took place weeks or months after long-range rocket launches.


Those tests were carried out under the rule Kim Jong Il, the deceased father of the current leader, and the man who channeled huge amounts of money into North Korea's nuclear and missile development programs.


Kim Jong Il died in December 2011 after 17 years in power, during which the North Korean people became increasingly impoverished and malnourished.


Economically, the country relies heavily on trade with its major ally, China.


On Tuesday, China's Foreign Ministry appealed for calm.


Spokesman Hong Lei urged North Korea and the West to "keep calm, remain cautious and refrain from any action that might escalate the situation in the region."


The U.S. Treasury Department on Thursday prohibited future transactions between Americans and two North Korean bankers and one financial service company the agency said support North Korea's nuclear program.

Battery expert: "I would not fly in a Dreamliner"

(CBS News) WASHINGTON - Investigators say they still don't know what caused batteries to burn in two Boeing 787 Dreamliners, and until they figure that out and how to fix the problem, none of the planes will be allowed to fly.

More than any other plane, the Dreamliner relies on lithium ion batteries to help power its advanced electrical system. They're lighter and more powerful than older battery types, but they contain a highly flammable liquid electrolyte.

U.S. officials defend handling of 787 mishaps

Boeing 787 probe turns to battery companies

Boeing plans to carry on with Dreamliner production

Federal investigators are examining the disassembled battery from the 787 that caught fire in Boston January 7, spewing molten electrolyte.

George Blomgren worked for Eveready, a batteries and flashlights company, for 40 years. He says lithium ion batteries are bundled together for the 787, and that increases the risk.

"These fires burn at very high temperatures, so they are just very dangerous fires," he said.

The Boston fire, and the burned-out battery on a Dreamliner in Japan, is not the first time lithium ion batteries have caused problems.

In 2011, a Chevy Volt lithium ion battery was damaged in a crash test. Three weeks later, it burst into flames. Chevrolet installed a number of fixes to prevent fires.

Safety features also were added to lithium ion batteries in some cell phones and laptops after 56 million were recalled for risk of overheating and exploding.

Boeing says lithium ion batteries "best met the performance and design objectives of the 787" and "Based on everything we know at this point, we have not changed our evaluation."

Blomgren considers the safety of lithium ion batteries on planes questionable.

"From what I know about incidents, I would not fly in a Dreamliner tomorrow. I just wouldn't feel that it was appropriate or safe," Blomgren said.

Many experts believe in the promise of lithium ion batteries, including for airlines, but they just aren't sure its safety has been perfected.

ht explosives in jeff co house tk 130124 wblog Federal Agents Bust Colorado Man in Alleged Bombs for Drugs Sting

Ryan Budnick/KMGH


A Colorado man who claimed to be a former demolition expert in the U.S. Marines was arrested Thursday after he allegedly tried to trade guns and homemade bombs with a 20-meter “kill zone” for cocaine.


Richard Lawrence Sandberg, 35, was taken into custody Thursday at his Morrison, Colo. home, ATF spokesman Bradley Beyersdorf told ABC News. Sandberg is facing one count of unlawful possession of a firearm or explosive device.


According to court documents, police became aware of Sandberg on January 18, when a confidential informant told a Denver police detective that Sandberg wanted to trade “numerous firearms and grenades” for drugs. The Denver police detective then contacted the Bureau of Alcohol, Tobacco, Firearms and Explosives.


On Tuesday, the documents say, an undercover ATF agent met with Sandberg at his home.


Sandberg allegedly told the undercover agent that he was in possession of 18 M67 military grenades that he offered to sell for $200 to $300 a piece, according to the criminal complaint.


The complaint did not say where Sandberg may have gotten the grenades, but said “Sandberg claimed to have been active in war zones in Iraq, Somalia, Africa, and Pakistan.”


“Sandberg also stated that he was in possession of several thousand rounds of ammunition and also in possession of uranium-tipped armor-piercing ammunition,” the complaint said.


In addition to the grenades, Sandberg allegedly claimed to have about a dozen homemade bombs, called “frags,” designed to create a “kill zone” within 20 meters and a “hurt zone” within 60 meters if they went off. The complaint says Sandberg also claimed to have access to C4 plastic explosives and napalm.


In one conversation, Sandberg “made disparaging remarks about the current administration and them wanting to take away his guns,” according to the complaint.

If any law enforcement officers tried to take his guns, the complaint says Sandberg told the agent that “it would be a bad day for them and lots of them would die. Sandberg stated that he was ready and willing to die.”


At one point, the undercover ATF agent offered to pay for pipe bombs and a small explosive called a “cricket.” Sandberg refused, the complaint says, instead insisting that “they could set up a trade for cocaine.”


During the Thursday operation, the street in front of Sandberg’s home was blocked for several hours while ATF agents and three local bomb squads made sure the house was safe. Multiple improvised explosive devices were taken from the house and rendered safe at a remote location,according to U.S. Attorney’s spokesman Jeffrey Dorchner.


One house next door to Sandberg’s had to be temporarily evacuated, Beyersdorf said.


Sandberg appeared in federal court Thursday afternoon and was advised of the charges against him. He has not entered a plea. Sandberg is being held without bond until a detention hearing scheduled for Jan. 29, Dorchner said.

Wallace: Wonders of nature have been solace of my life






















Alfred Russel Wallace discovered natural selection independently of Charles Darwin. Through his letters, available online for the first time, he tells us of his research, expeditions and enduring fascination for nature's mysteries.






















You are famously joint author, with Darwin, of the first paper describing the origin of species and natural selection, published in 1858. When did you first get the idea?
I begin [in 1847] to feel rather dissatisfied with a mere local collection – little is to be learnt by it. I sh[ould]d like to take some one family, to study thoroughly – principally with a view to the theory of the origin of species. By that means I am strongly of [the] opinion that some definite results might be arrived at.












This desire led you to Brazil to collect birds, butterflies and beetles to try to discover what drives the evolution of new species. Were there any incidents on the voyage?
On Friday the 6th of August [1852]… the Captain (who was the owner of the vessel) came into the cabin & said "I am afraid the ship's on fire. Come & see what you think of it."












Despite that harrowing experience, you next undertook an 8 year expedition to the Malay Archipelago, where you discovered the invisible boundary between the animals of Asia and the Australian region, which would later be called the Wallace Line in your honour. What fascinated you most on that trip?
The Birds have however interested me much more than the insects, they are proportionally much more numerous, and throw great light on the laws of Geographical distribution of Animals in the East… As an instance I may mention the Cockatoos, a group of birds confined to Australia & the Moluccas, but quite unknown in Java Borneo Sumatra & Malacca… Many other species illustrate the same fact.












You have been famously good-natured about sharing the discovery of natural selection with Darwin…
I also look upon it as a most fortunate circumstance that I had a short time ago commenced a correspondence with Mr. Darwin on the subject of "Varieties", since it has led to the earlier publication of a portion of his researches & has secured to him a claim to priority which an independent publication either by myself or some other party might have injuriously effected












What did you and Darwin have in common?
In early life both Darwin and myself became ardent beetle-hunters. Both Darwin and myself had, what he terms "the mere passion of collecting"… Now it is this superficial and almost child-like interest in the outward forms of living things, which, though often despised as unscientific, happened to be the only one which would lead us towards a solution of the problem of species.












Do you feel your contribution has been overlooked?
The idea came to me, as it had come to Darwin, in a sudden flash of insight: it was thought out in a few hours – was written down with such a sketch of its various applications and developments… then copied on thin letter-paper and sent off to Darwin – all within one week.












I should have had no cause for complaint if the respective shares of Darwin and myself in regard to the elucidation of nature's method of organic development had been thenceforth estimated as being, roughly, proportional to the time we had each bestowed upon it when it was thus first given to the world – that is to say, as 20 years is to one week.












You helped Darwin with the puzzle of bright colouration in animals, which led to the concept of warning colours. To ask his question again, why are some caterpillars so brightly coloured?
[Since some]… are protected by a disagreeable taste or odour, it would be a positive advantage to them never to be mistaken for any of the palatable caterpillars… Any gaudy & conspicuous colour therefore, that would plainly distinguish them from the brown & green eatable caterpillars, would enable birds to recognise them easily as a kind not fit for food, & thus they would escape seizure which is as bad as being eaten.












How did you feel looking back on your life's work, at the age of 89?
The wonders of nature have been the delight and solace of… life. Nature has afforded… an ever increasing rapture, and the attempt to solve some of her myriad problems an ever-growing sense of mystery and awe.












Do you have a message for our readers?
I sincerely wish you all some of the delight in the mere contemplation of nature's mysteries and beauties which I have enjoyed.

More covered linkways, elderly friendly bridges for commuters






SINGAPORE: The government will spend close to S$700 million to make transport nodes more accessible, elderly friendly and conducive for commuters.

The plans, mapped out in the new Land Transport Master Plan, were announced by Transport Minister Lui Tuck Yew on Wednesday.

One of the new initiatives -- Walk2Ride -- will make it easier for more commuters to walk to MRT stations.

The Land Transport Authority (LTA) will build sheltered linkways within a 400-metre radius from all existing MRT stations, compared to the current radius of 200 metres.

LTA will also link up developments within a 200-metre radius of all bus interchanges, LRT stations and high-usage bus shelters.

In all, some 200 kilometres of linkways will be added islandwide by 2018, more than four times the existing 46 kilometres today.

The project is expected to cost some S$330 million and will begin from 2014.

Currently, sheltered linkways are built to link only to schools, healthcare institutions and other transport nodes like bus stops and taxi stands.

But under Walk2Ride, shopping, leisure, commercial and residential areas will also be linked.

LTA intends to leverage on existing linkways and work with the different town councils before deciding on which areas will be given priority.

The Walk2Ride initiative is being rolled out, following a successful trial at Lakeside MRT.

More pedestrian overhead bridges will also become more elderly and wheel-chair friendly.

LTA has reviewed the provision criteria to build more lifts at such bridges. These include those located within 200 metres of MRT stations and 100 metres of LRT stations.

Some 40 bridges have been identified for further feasibility studies.

A budget of about S$60 million has been set aside to install the lifts from 2014. Half of them will be completed by 2016 and the remaining by 2018.

Another S$300 million will be spent on installing some 20 kilometres of noise barriers along elevated MRT tracks.

Since September, LTA has been measuring noise levels at 455 residential flats located close to such tracks.

In some locations, the noise levels were found to have exceeded the National Environment Agency's guideline of 67 decibels.

Mr Lui said residents living close to MRT viaducts, such as those in Simei, Marsiling and Dover, can expect noise levels to be reduced by about five to 10 decibels.

LTA intends to start installing the barriers from end of this year and complete them by 2020.

Prosecutor: Disabled victims held 'like zoo animals'






STORY HIGHLIGHTS


  • Five indicted in alleged fraud, abuse scheme

  • Indictment alleges hate crimes

  • Two victims died

  • Alleged ringleader could face death penalty




Philadelphia (CNN) -- Four adults imprisoned in a dark Philadelphia boiler room, beaten and underfed, were confined like zoo animals, federal prosecutors said Wednesday in announcing a 196-count indictment against their alleged captors.


The litany of federal charges against the alleged ringleader and her posse is the first hate crime case of its kind -- the victims were mentally and physically disabled, the U.S. Attorney's Office said.


Charges against the five defendants, together and individually, include sex trafficking, murder, fraud and forced human labor, among others.


The defendants, according to prosecutors, held the four victims in subhuman conditions in a scheme to steal Social Security disability payments.




Linda Ann Weston, 52, was described by police as the ringleader of an alleged fraud and abuse scheme.



Linda Ann Weston, 52, whom police have described as the ringleader, her daughter, Jean McIntosh, 33, Gregory Thomas, Sr., 49, Eddie Wright, 52, and Nicklaus Woodard, 26, are accused of using isolation, intimidation, threats of violence and violence to control the victims and each defendant had a role in the racketeering enterprise, according to the indictment.


Brother of basement captive describes emotional reunion


The investigation into Weston and her alleged co-conspirators began when the four adults were found in October 2011 locked in the sub-basement room with no food and only a bucket for a toilet.


According to the indictment, the defendants beat the victims, kept them captive in locked closets, basements and attics, deprived them of adequate food and medical care, and moved them between Pennsylvania, Texas, Virginia, and Florida in order to further the scheme and evade law enforcement.


The defendants also are charged with violating the Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act -- which criminalizes violence motivated by any person's actual or perceived disability, race, color, national origin, religion, sexual orientation, gender, or gender identity -- for their alleged actions against the disabled victims.


"The physically and mentally disabled are among the most vulnerable in our society. They deserve to be treated with respect and compassion, not violence," U.S Attorney Zane David Memeger said in a statement. "Linda Weston and others, in fact, decided to prey on these victims specifically because of their physical and mental challenges and they did so through violence, fear and intimidation for the purpose of stealing Social Security payments that were meant for the victims' long-term care."


As the first hate crimes case of its kind because the victims were disabled, the indictment alleges that Weston's "abusive control and confinement techniques" caused the deaths of two of the victims, including Weston's former roommate, Maxine Lee, who she allegedly continued to collect benefits from after she died of acute meningitis.


The medical examiner said a contributing factor in Lee's death was "cachexia of unknown origin," or malnutrition. The manner of death is listed as "natural causes."


New details emerge in case of people held captive in Philadelphia


"Shocking does not begin to describe the criminal allegations in this case where the victims were tied up and confined like zoo animals and treated like property akin to slaves," Memeger said.


The four adults held captive -- Edwin Sanabria, Herbert Knowles, Tamara Breeden and Derwin McLemire -- were locked in a pitch-black, 13-by-7 foot room that housed the former boiler used to heat the building, police said.


A penetrating stench of urine and feces still hung in the chamber days after the discovery. McLemire had been chained to the boiler, police said.


"I used the bucket to go to the bathroom. Others used the same bucket," Sanabria testified last January at hearing where a judge ordered the case to go to trial. When asked where he took a bath, he said they "used the same bucket we used to urinate in."


Lawyer: Police contacted in 2003 about chief suspect


The investigation took several bizarre twists as authorities tried to piece together the evidence in the case, which has spread to at least two other states after detectives discovered that one of the accused had traveled across state lines with the people found in the boiler room.


"Today's Indictment represents just one more step towards closure and healing, not only for the victims of this heinous hate crime, but for the community as a whole," FBI Special Agent-in-Charge John Brosnan said in a statement.


If convicted of all federal charges, each of the defendants faces a statutory maximum sentence of life in prison. Weston potentially faces the death penalty and mandatory restitution of approximately $212,000.


Due to the federal charges, the state plans to withdraw its charges against Weston, Thomas, Wright and McIntosh, according to the district attorney's office in Philadelphia. They were scheduled to go on trial January 28.
