(AP) ? Like countless other Syrians fleeing their country's civil war, Sami was eager to escape the bombs and artillery shells falling on his village. But instead of taking his family to another country, he simply brought them underground.

For the past seven months, the family has lived in a chamber cut into the rock of the Jebel al-Zawiya hills, its walls etched with arabesques and alcoves.

Sami, a 32-year-old stonecutter, believes that his new home is a Roman shrine. Its design in fact suggests it may be a tomb.

Across northern Syria, rebels, soldiers and civilians are making use of the country's wealth of ancient and medieval remains for protection. The structures are built of thick stone that has already withstood the ravages of centuries. They are often located in strategic spots overlooking towns and roads.

Sami, who like many Syrians was reluctant to give his full name for security reasons, says cave life is hard. The worst part isn't the lack of electricity or running water. It's the smoke from the indoor fires.

"We go daily to the doctor for our children," he said. His youngest, a 2-month-old girl named Abir, has been badly afflicted with respiratory problems.

But he considers the discomfort and health risks of the cave preferable to the terror of life above ground, with forces loyal to President Bashar Assad controlling the skies. "At any moment they can strike," he said. "I have no other option until the regime falls."

Combatants on both sides in the civil war frequently use medieval fortifications, often the legacy of the centuries-long contest between Christian and Muslim empires for the control of this region.

In the town of Harem on the Turkish border, rebels fought a bloody battle in December to oust the regime from a hilltop fortress previously used by Byzantines, the allies of Saladin, and the Crusaders. Video shows fighters painstakingly making their way in single file up the side of the cliff to capture the citadel.

In the town of Maaret al-Numan in the plain below the Jebel al-Zawiya, rebels have set up their headquarters in a 17th-century caravansary, now a museum. Its solid fortress-like walls seem to have withstood the nearly daily rocket and mortar strikes far better than nearby modern buildings have. A stroll through the halls triggers the motion-sensitive lights, illuminating a Roman mosaic of a lion tearing the flesh of a bull.

Archaeologists have raised concerns about the damage done by the war. Fighting in the city of Aleppo has raged around a 12th century citadel, and a fire in September destroyed much of a medieval souk that is part of a UNESCO World Heritage site.

One young fighter in the Jebel al-Zawiya who gave his name as Abu Mohammed said that before the war, inhabitants of this region drew little benefit from the tourism that the ruins attracted. Instead, regime security forces would shoo away anyone who came nearby. Residents feared going closer for fear they would be accused of looting and then imprisoned and tortured, he said.

"We used to be scared to go near the monuments," he said, showing a reporter the cave that he and his fellow villages use for shelter. "But now, they're benefiting us."

Panel: change sentencing in child porn cases

WASHINGTON (AP) ? The U.S. Sentencing Commission says the advent of the Internet has led to broad sentencing disparities in child pornography cases and that the existing penalty structure needs to be changed.

In a study for Congress, the commission said Wednesday that federal law enforcement agencies handle nearly 2,000 child pornography prosecutions annually, up from 700 a decade ago. It attributed that increase largely to pornographers exploiting the Internet.

The report says the current sentencing scheme fails to distinguish adequately among offenders based on how dangerous they are, and is overly severe in some cases.

Blueprint for an artificial brain: Scientists experiment with memristors that imitate natural nerves

Feb. 26, 2013 ? Scientists have long been dreaming about building a computer that would work like a brain. This is because a brain is far more energy-saving than a computer, it can learn by itself, and it doesn't need any programming. Privatdozent [senior lecturer] Dr. Andy Thomas from Bielefeld University's Faculty of Physics is experimenting with memristors -- electronic microcomponents that imitate natural nerves. Thomas and his colleagues have demonstrated that they could do this a year ago. They constructed a memristor that is capable of learning. Andy Thomas is now using his memristors as key components in a blueprint for an artificial brain.

He will be presenting his results at the beginning of March in the print edition of the Journal of Physics published by the Institute of Physics in London.

Memristors are made of fine nanolayers and can be used to connect electric circuits. For several years now, the memristor has been considered to be the electronic equivalent of the synapse. Synapses are, so to speak, the bridges across which nerve cells (neurons) contact each other. Their connections increase in strength the more often they are used. Usually, one nerve cell is connected to other nerve cells across thousands of synapses.

Like synapses, memristors learn from earlier impulses. In their case, these are electrical impulses that (as yet) do not come from nerve cells but from the electric circuits to which they are connected. The amount of current a memristor allows to pass depends on how strong the current was that flowed through it in the past and how long it was exposed to it.

Andy Thomas explains that because of their similarity to synapses, memristors are particularly suitable for building an artificial brain -- a new generation of computers. 'They allow us to construct extremely energy-efficient and robust processors that are able to learn by themselves.' Based on his own experiments and research findings from biology and physics, his article is the first to summarize which principles taken from nature need to be transferred to technological systems if such a neuromorphic (nerve like) computer is to function. Such principles are that memristors, just like synapses, have to 'note' earlier impulses, and that neurons react to an impulse only when it passes a certain threshold.

Thanks to these properties, synapses can be used to reconstruct the brain process responsible for learning, says Andy Thomas. He takes the classic psychological experiment with Pavlov's dog as an example. The experiment shows how you can link the natural reaction to a stimulus that elicits a reflex response with what is initially a neutral stimulus -- this is how learning takes place. If the dog sees food, it reacts by salivating. If the dog hears a bell ring every time it sees food, this neutral stimulus will become linked to the stimulus eliciting a reflex response. As a result, the dog will also salivate when it hears only the bell ringing and no food is in sight. The reason for this is that the nerve cells in the brain that transport the stimulus eliciting a reflex response have strong synaptic links with the nerve cells that trigger the reaction.

If the neutral bell-ringing stimulus is introduced at the same time as the food stimulus, the dog will learn. The control mechanism in the brain now assumes that the nerve cells transporting the neutral stimulus (bell ringing) are also responsible for the reaction -- the link between the actually 'neutral' nerve cell and the 'salivation' nerve cell also becomes stronger. This link can be trained by repeatedly bringing together the stimulus eliciting a reflex response and the neutral stimulus. 'You can also construct such a circuit with memristors -- this is a first step towards a neuromorphic processor,' says Andy Thomas.

'This is all possible because a memristor can store information more precisely than the bits on which previous computer processors have been based,' says Thomas. Both a memristor and a bit work with electrical impulses. However, a bit does not allow any fine adjustment -- it can only work with 'on' and 'off'. In contrast, a memristor can raise or lower its resistance continuously. 'This is how memristors deliver a basis for the gradual learning and forgetting of an artificial brain,' explains Thomas.

Stretchable batteries are here! Power to the bendy electronics

The next frontier in electronics are the flexible, stretchable kind. Yes, that means a rubber, bouncy smartphone (eventually), but it also means heart monitors threaded into cardiac tissue. For devices like that to work, they require flexible, stretchable batteries. And such batteries are here, according to researchers who just published their work.

Yonggang Huang, an engineer at Northwestern University, created the battery with materials wizard John Rogers at the University of Illinois, who received the $500,000 Lemelson-MIT Prize in 2011 for his work on flexible electronics designed for integration with the human body.

How much give and take does the invention allow? ?We can stretch the device a great deal ? up to about 300 percent ? and still have a working battery,? Huang noted. (Please don't try that with your smartphone's battery.)

?Such stretchable batteries enable true integration with stretchable electronics in a small package,? Huang told NBC News in an email.

The background of the research team means that medical applications will be primarily targeted, but there are other applications for bendy batteries such as wearable solar cells and electric-eye cameras that make studio-quality photographs.

The flexible lithium-ion battery reported today in the journal Nature Communications completes the flexible electronics package with a cordless power source. When the battery runs out of juice after about eight hours, it is recharged wirelessly.

To make the battery, the researchers start with tiny, individual, rigid battery storage components arranged next to each other. The bendy and stretchy characteristics stem from tightly packed, wavy wires that connect these components.

?When we stretch the battery, the wavy interconnects unravels, much like yarn unspooling, while the storage components almost keep undeformed, because of their much larger rigidity than the interconnects? Huang explained.

The breakthrough was demonstrated with a light emitting diode that continues to work when stretched, folded and twisted on a human elbow. It continued to work well through 20 recharge cycles.

Column: No big compromises? Blame party power

WASHINGTON (AP) -- These days, it sounds like an improbable fairy tale: politicians with deeply differing visions of America setting aside disagreements to reach a grand compromise on a critical issue.

That's exactly what happened in 1790, when the Founding Fathers overlooked their parochial interests ? and defied their staunchest backers ? by agreeing, for the good of the fledgling union, to put America's capital in a neutral place along the Potomac River.

Would the same outcome happen today? Fat chance.

In this polarized and partisan era, Washington careens from one crisis to the next even as the country faces huge problems that threaten its standing in the world. With power divided on Capitol Hill, bipartisan solutions are necessary. And yet, while both Democrats and Republicans talk a lot about compromise ? a cross-the-aisle, solutions-driven approach ? few seem willing to give ground to fix what ails the nation.

The latest example is the stalemate over deep budget cuts set to take effect Friday, absent a bipartisan deal. The cuts likely will inconvenience average Americans and may slow the nation's fragile economic recovery. Both sides are dug in on their ideological positions. President Barack Obama and his Democrats want more tax increases, while Republicans demand more spending cuts.

This is the fifth fiscal standoff since this period of divided government began in 2011, when Republicans took over the House while Democrats continued to control the Senate. In the other cases, both sides reached mini-deals to avert immediate crisis ? only to ignore the larger issues. Skyrocketing debt and persistent deficits. Rampant waste, fraud and abuse. Budget-busting Social Security and Medicare programs.

Why does Washington get so caught up this cycle of panic ? whether manufactured or real ? only to ultimately put a Band-Aid on the country's biggest gushers without ever mending the underlying wounds?

Politicians have little incentive to take the risk of working with the opposing party to reach solutions that will fundamentally fix a problem. They operate in a system that makes it hard to roll the dice because they're putting their own jobs on the line. Robust Republican and Democratic parties ? and their conservative and liberal activists, whose voices drown out the centrist Americans seeking remedies ? usually rebuke them rather than reward them.

"Rebels, risk takers and creative thinkers are marginalized early and are seldom promoted up the ladder of local/state/national politics," says David A. Drupa of the Society for Risk Analysis.

These days, he says, politicians seem to be allowing the short-term benefit for themselves ? winning re-election ? drive their decision-making, without getting far enough along in their return-on-investment analysis to examine the long-term benefit for the nation.

"They're trying to win the next battle, the next matchup, the next race, at all our peril," Drupa says.

Both parties promise to use their bank accounts to protect lawmakers who stick with their ideological positions, and punish those who don't. Deep-pocketed groups on the far right and far left also go after those deemed unfaithful.

At the same time, party leaders have proven extraordinarily successful in drawing congressional boundaries in a way that actually discourages House members from collaborating and all but ensures their re-elections if they don't. Most districts are stocked with hard-core Republicans and Democrats who typically will vote for lawmakers only if they demonstrate consistent party loyalty.

So the easy thing for lawmakers to do is just that. It's much harder to meet in the middle.

Thus, when Washington's players do end up compromising on the meaty matters, it's usually in a piecemeal way that kicks the larger problems to future generations. Those who dare to try to solve the big problems typically find they lack the juice, lose re-election or get so fed up with the gridlock that they retire.

All this is precisely what George Washington worried would happen if the country devolved into factions.

"He thought political parties would tear up the union and it wouldn't survive," says Willard Sterne Randall, a biographer and historian who has written several books on the Founding Fathers.

The first president's fear of factionalism was so great that he decided on a second term as Alexander Hamilton and Thomas Jefferson, whose political bases were businessmen and farmers, respectively, battled over competing visions for the union.

Yet while they differed, they also compromised when necessary ? as they did during the "Dinner Table Bargain" that resulted in Washington becoming the nation's capital instead of New York, Philadelphia or elsewhere.

"They weren't at each other's throats politically. They could get together on a major issue," Randall says. "They wanted the union to survive, so they compromised where they had to for the good of it. That's the kind of tone there was. They were pragmatic idealists, and in Congress now, they are ideologues."

So how do we get back to those more reasonable roots?

The Democratic and Republican parties are strong, and they probably won't face serious threats from third parties in the near future. They certainly won't eliminate gerrymandering unless voters force it.

So maybe it's time for something radical, or at least radically reasonable. Maybe this is the moment for a few of the frustrated Americans in the middle ? many of whom reject the extremes, complain about stalemate and fear for the nation's future ? to take a risk.

What if they stepped forward as candidates with a promise that they'll do only what they think will solve the country's big problems, regardless of what it could mean for their political careers? What if they rejected the strict adherence to orthodoxy that party bosses demand? What if they promised to only serve one term, choosing explicitly to put the country's future over their own?

And then, by not going to Congress primarily to get re-elected, they just might end up with a surprising reward: getting re-elected.

Wouldn't the country ? not to mention this supposedly neutral city on the banks of the Potomac ? be better for it?

(AP) ? "Star Trek" fans, rejoice.

An online vote to name Pluto's two newest, itty-bitty moons is over. And No. 1 is Vulcan, a name suggested by actor William Shatner, who played Capt. Kirk in the original "Star Trek" TV series.

Vulcan snared nearly 200,000 votes among the more than 450,000 cast during the two-week contest, which ended Monday. In second place with nearly 100,000 votes was Cerberus, the three-headed dog that guarded the gates of the underworld.

Vulcan was the Roman god of lava and smoke, and the nephew of Pluto. Vulcan was also the home planet of the pointy-eared humanoids in the "Star Trek" shows. Think Mr. Spock.

"174,062 votes and Vulcan came out on top of the voting for the naming of Pluto's moons. Thank you to all who voted!" Shatner said in a tweet once the tally was complete.

Actor Leonard Nimoy, who portrayed the reason- and logic-based Spock, had this to say in an email to The Associated Press: "If my people were emotional they would say they are pleased."

Don't assume Vulcan and Cerberus are shoo-ins, though, for the two tiny moons discovered over the past two years with the Hubble Space Telescope.

The contest was conducted by SETI Institute in Mountain View, Calif., the research base for the primary moon hunter. The 10 astronomers who made the discoveries will take the voting results into account, as they come up with what they consider to be the two best names.

The International Astronomical Union has the final say, and it could be another month or two before an edict is forthcoming. Now known as P4 and P5, the moons are 15 to 20 miles across.

The leader of the teams that discovered the mini-moons, Mark Showalter said Monday he is leaning toward the popular vote.

But Showalter pointed out that asteroids thought to orbit close to the sun are called vulcanoids, and there could be some confusion if a moon of Pluto were to be named Vulcan. Vulcan, in fact, was the name given in the 19th century to a possible planet believed to orbit even closer to the sun than Mercury; no such planet ever was found.

What's more, Showalter said in a phone interview, Vulcan is associated with lava and volcanoes, while distant Pluto is anything but hot.

As for Cerberus, an asteroid already bears that name, so maybe the Greek version, Kerberos, would suffice, said Showalter, a senior research scientist at SETI's Carl Sagan Center.

Styx landed in No. 3 position with nearly 88,000 votes. That's the river to the underworld.

Pluto's three bigger moons are Charon, Nix and Hydra.

To be considered, the potential names for the two mini-moons also had to come from Greek or Roman mythology, and deal with the underworld. Twenty-one choices were available at the website http://www.plutorocks.com when voting ended Monday. Of those, nine were write-in candidates suggested by the public, including Shatner's entry for Vulcan.

Shatner's second choice for a name, Romulus, did not make the cut. That's because an asteroid already has a moon by that name ? along with a moon named Remus.

And forget the Disney connection.

"We love Mickey, Minnie and Goofy, too," Showalter informed voters a few days into the voting. "However, these are not valid names for astronomical objects. Sorry."

Altogether, 30,000 write-in candidate names poured in.

Showalter said he will keep the list handy as more moons undoubtedly pop up around Pluto once NASA's New Horizons spacecraft arrives in 2015. It will be the first robotic flyby ever of the planetoid, or dwarf planet near the outer fringes of the solar system.

"I have learned not to underestimate Pluto," Showalter wrote on the website. With so many good names available, "Pluto needs more moons!"

(AP Photo)

(AP) ? Oscar Pistorius on Monday informed South African authorities that he wants to resume athletic training while on bail for the murder case against him, a government official said.

A spokeswoman for the Olympic runner, however, denied that he was making immediate plans to return to the track while awaiting trial for the Feb. 14 shooting death of his girlfriend, Reeva Steenkamp.

"Absolutely not," said spokeswoman Janine Hills. "He is currently in mourning and his focus is not on his sports."

The double-amputee Paralympian discussed bail terms with his probation officer and a correctional official at the Pretoria Magistrate's Court in the capital, according to correctional officials. The guidelines will determine his daily routine until his next court appearance on June 4.

"It's his wish to continue to practice," James Smalberger, chief deputy commissioner of the department of correctional services, said in a telephone interview with The Associated Press.

Smalberger said the issue came up because authorities need to know his movements whenever he leaves the home where he is staying.

The timing of any resumption of training was uncertain.

Pistorius' longtime coach, Ampie Louw, declined to comment on any training plans for the runner, referring questions to a spokeswoman for the athlete's family.

Louw had said when the runner was in detention that he wanted to put him back into training in the event that he was granted bail. But he had also said Pistorius could be "heartbroken" and unwilling to immediately run again.

Pistorius, who was released on bail Friday, is staying at the house of his uncle, Arnold, in the affluent suburb of Waterkloof in Pretoria. He faces life imprisonment if convicted.

Pistorius is charged with premeditated murder in the killing of Steenkamp, in the early hours of Valentine's Day. Prosecutors say the pair had an argument before Steenkamp was killed; Pistorius says he mistook her for an intruder and shot her accidentally.

Smalberger said officials will visit Pistorius at his uncle's home at least four times a month, and that the runner indicated his interest in training again. More planning must occur before the start of any training.

"We want a training program from his coach so that we have backup for his movements," Smalberger said.

"He's not under house arrest, but his movements need to be known to us so that we don't pitch there and he's not there," he said. "We agree on 'free time' normally during the course of the day, and in the evening we expect him to be home."

Pistorius' 2013 season had been geared towards the Aug. 10-18 World Championships in Moscow, where the South African 4x400 relay team will be trying for another medal to add to the silver it won at the 2011 edition.

Chief Magistrate Desmond Nair had set bail at 1 million rand ($113,000). The 26-year-old track star was also ordered to hand over his passports, turn in any guns he owns and keep away from his upscale home in a gated community in Pretoria, the scene of the crime.

He cannot leave the district of Pretoria without his probation officer's permission and is not allowed to consume drugs or alcohol, the magistrate said.

Fruit flies force their young to drink alcohol for their own good

Feb. 22, 2013 ? The fruit fly study adds to the evidence "that using toxins in the environment to medicate offspring may be common across the animal kingdom," says biologist Todd Schlenke.

When fruit flies sense parasitic wasps in their environment, they lay their eggs in an alcohol-soaked environment, essentially forcing their larvae to consume booze as a drug to combat the deadly wasps.

The discovery by biologists at Emory University is being published in the journal Science on February 22.

"The adult flies actually anticipate an infection risk to their children, and then they medicate them by depositing them in alcohol," says Todd Schlenke, the evolutionary geneticist whose lab did the research. "We found that this medicating behavior was shared by diverse fly species, adding to the evidence that using toxins in the environment to medicate offspring may be common across the animal kingdom."

Adult fruit flies detect the wasps by sight, and appear to have much better vision than previously realized, he adds. "Our data indicate that the flies can visually distinguish the relatively small morphological differences between male and female wasps, and between different species of wasps."

The experiments were led by Balint Zacsoh, who recently graduated from Emory with a degree in biology and still works in the Schlenke lab. The team also included Emory graduate student Zachary Lynch and postdoc Nathan Mortimer.

The larvae of the common fruit fly, Drosophila melanogaster, eat the rot, or fungi and bacteria, that grows on overripe, fermenting fruit. They have evolved a certain amount of resistance to the toxic effects of the alcohol levels in their natural habitat, which can range up to 15 percent.

Tiny, endoparasitoid wasps are major killers of fruit flies. The wasps inject their eggs inside the fruit fly larvae, along with venom that aims to suppress their hosts' cellular immune response. If the flies fail to kill the wasp egg, a wasp larva hatches inside the fruit fly larva and begins to eat its host from the inside out.

Last year, the Schlenke lab published a study showing how fruit fly larvae infected with wasps prefer to eat food high in alcohol. This behavior greatly improves the survival rate of the fruit flies because they have evolved high tolerance of the toxic effects of the alcohol, but the wasps have not.

"The fruit fly larvae raise their blood alcohol levels, so that the wasps living in their blood will suffer," Schlenke says. "When you think of an immune system, you usually think of blood cells and immune proteins, but behavior can also be a big part of an organism's immune defense."

For the latest study, the researchers asked whether the fruit fly parents could sense when their children were at risk for infection, and whether they then sought out alcohol to prophylactically medicate them.

Adult female fruit flies were released in one mesh cage with parasitic wasps and another mesh cage with no wasps. Both cages had two petri dishes containing yeast, the nourishment for lab-raised fruit flies and their larvae. The yeast in one of the petri dishes was mixed with 6 percent alcohol, while the yeast in the other dish was alcohol free. After 24 hours, the petri dishes were removed and the researchers counted the eggs that the fruit flies had laid.

The results were dramatic. In the mesh cage with parasitic wasps, 90 percent of the eggs laid were in the dish containing alcohol. In the cage with no wasps, only 40 percent of the eggs were in the alcohol dish.

"The fruit flies clearly change their reproductive behavior when the wasps are present," Schlenke says. "The alcohol is slightly toxic to the fruit flies as well, but the wasps are a bigger danger than the alcohol."

The fly strains used in the experiments have been bred in the lab for decades. "The flies that we work with have not seen wasps in their lives before, and neither have their ancestors going back hundreds of generations," Schlenke says. "And yet, the flies still recognize these wasps as a danger when they are put in a cage with them."

Further experiments showed that the flies are extremely discerning about differences in the wasps. They preferred to lay their eggs in alcohol when female wasps were present, but not if only male wasps were in the cage.

Theorizing that the flies were reacting to pheromones, the researchers conducted experiments using two groups of mutated fruit flies. One group lacked the ability to smell, and another group lacked sight. The flies unable to smell, however, still preferred to lay their eggs in alcohol when female wasps were present. The blind flies did not make the distinction, choosing the non-alcohol food for their offspring, even in the presence of female wasps.

"This result was a surprise to me," Schlenke says. "I thought the flies were probably using olfaction to sense the female wasps. The small, compound eyes of flies are believed to be more geared to detecting motion than high-resolution images."

The only obvious visual differences between the female and male wasps, he adds, is that the males have longer antennae, slightly smaller bodies, and lack an ovipositor.

Further experimentation showed that the fruit flies can distinguish different species of wasps, and will only choose the alcohol food in response to wasp species that infect larvae, not fly pupae. "Fly larvae usually leave the food before they pupate," Schlenke explains, "so there is likely little benefit to laying eggs at alcoholic sites when pupal parasites are present."

The researchers also connected the exposure to female parasitic wasps to changes in a fruit fly neuropeptide.

Stress, and the resulting reduced level of neuropeptide F, or NPF, has previously been associated with alcohol-seeking behavior in fruit flies. Similarly, levels of a homologous neuropeptide in humans, NPY, is associated with alcoholism.

"We found that when a fruit fly is exposed to female parasitic wasps, this exposure reduces the level of NPF in the fly brain, causing the fly to seek out alcoholic sites for oviposition," Schlenke says. "Furthermore, the alcohol-seeking behavior appears to remain for the duration of the fly's life, even when the parasitic wasps are no longer present, an example of long-term memory."

Finally, Drosophila melanogaster is not unique in using this offspring medication behavior. "We tested a number of fly species," Schlenke says, "and found that each fly species that uses rotting fruit for food mounts this immune behavior against parasitic wasps. Medication may be far more common in nature than we previously thought."

Plants 'talk' to bees with electricity, say scientists

Bees use the weak electrical charge carried by plants to determine if they have nectar, a new study has found.?

By Marc Lallanilla,?LiveScience Assistant Editor / February 22, 2013

Bees can sense a flower's electrical charge, which tells them if the flower's worth visiting.

Everyone knows that bees buzz around flowers in their quest for nectar. But scientists have now learned that flowers are buzzing right back ? with electricity.

Skip to next paragraph

Plants generally have a negative electrical charge and emit a weak electrical signal, according to researchers at the University of Bristol in England. And scientists have known for years that bees' flapping wings create a positive electrical charge of up to 200 volts as they flit from flower to flower, according to a news release.

But can the bees detect flowers' electrical charge? While animals like?sharks are known to sense electrical fields, nobody had ever found that an insect could do the same,?ScientificAmerican?reports.

To test the bees' sensitivity, researchers filled a room with artificial flowers: Half of the flowers were electrically charged and carried a sugary reward, while the other half had no charge and a bitter solution of quinine.

The bees quickly learned to visit only the electrically charged flowers, and to not waste their energy visiting flowers with no electrical charge. But when the electrical charges were switched off, the bees once again visited flowers randomly, suggesting that they had been reacting to the electrical charges. [The 10 Weirdest Animal Discoveries]

"Animals are just constantly surprising us as to how good their senses are," Dominic Clarke, lead author of the study, published in journal?Science, told the?BBC. "More and more we're starting to see that nature's senses are almost as good as they could possibly be."

Bees and flowers, of course, co-evolved with a long-standing symbiotic relationship: The bees depend on flowers for nectar, which they use to produce honey, and flowers need bees to help pollinate other flowers.

Flowers use various means to attract bees and other pollinators. In addition to their electrical charge and alluring fragrance, flowers display bright colors ? and research has found that?bees see colors?three times faster than humans.

But bees ? busy as they famously are ? don't have time to waste visiting pretty flowers whose nectar has just been taken by another insect. "The last thing a flower wants is to attract a bee and then fail to provide nectar," said Daniel Robert, co-author of the study, in a statement. "Bees are good learners and would soon lose interest in such [an] unrewarding flower."

So flowers, the researchers confirmed, emit a different electrical signal after their nectar has been harvested. They found that petunias became slightly more positively charged after a bee visited them, according to ScientificAmerican.

That revised electrical charge acts as a kind of "No Vacancy" sign to other bees, which learn to trust the signals that the flowers emit.

"This is a magnificent interaction where you have an animal and a plant, and they both want this to go as well as possible," study co-author?Gregory Sutton told NPR. "The flowers are trying to make themselves look as different as possible. This is to establish the flower's brand."

How do bees sense an electrical charge? Researchers aren't sure, but they suspect the fuzzy hairs on bees' bodies "bristle up" under an electrostatic force, just like hair in front of a television screen.

Other scientists are excited about the possible implications this research may have for other nectar-gathering insects such as hoverflies and moths.

"We had no idea that this sense even existed," Thomas Seeley, a behavioral biologist at Cornell University, told ScientificAmerican. "Assuming we can replicate the findings, this is going to open up a whole new window on insect sensory systems."

More states consider ban on credit card surcharges

Charge a fee to use your credit card? It?s legal for merchants to do that, unless barred by state law. Ten states already ban such surcharges ? California, Colorado, Connecticut, Florida, Kansas, Maine, Massachusetts, New York, Oklahoma and Texas ? and more may join the list.

The legislatures in 13 other states are currently considering bills that would prevent these so-called ?check out? fees. Lawmakers in Hawaii, Illinois, Kentucky, Maryland, Missouri, New Jersey, Pennsylvania, Rhode Island, South Carolina, Utah, Vermont, Washington and Tennessee are responding to a rule change that took place late last month. A similar bill will soon be introduced in West Virginia.

Visa and MasterCard agreed to let merchants add a surcharge to credit card transactions as part of the settlement agreement in an antitrust lawsuit brought by retailers. Until Jan. 27, both Visa and MasterCard had prohibited merchants from charging the customer for the cost of processing that credit card transaction.

The settlement does not affect Visa or MasterCard debit cards. American Express still prohibits a surcharge on any of its cards.

New Jersey Assemblyman Vincent Prieto (D-Secaucus) said he introduced a bill to ban surcharging because it would hit consumers in the pocketbook.

?The amount of the surcharge may seem miniscule on paper, but in the family budget 1.5 to 3 percent could add up to a shorter grocery list or less to spend on gas,? he said in a statement.

In Utah, Sen. Curtis Bramble (R-Provo) is sponsoring a bill that would prohibit surcharges on any type of ?financial transaction card? which would include debit cards.

Major retailers are not expected to tack on a credit card surcharge, at least not any time in the immediate future. Wal-Mart, Target, Sears and Home Depot told NBC News they have no plans to add a credit card surcharge. But just the possibility has spurred some lawmakers into action.

?It?s a waste of the legislative process,? said Mallory Duncan, senior vice president of the National Retail Federation. ?They could take steps to bring greater competition into the marketplace by prohibiting the price fixing of the hidden swipe fees merchants pay to process credit card transactions.?

Trish Wexler, spokesperson for the Electronic Payments Coalition, whose members include Visa and MasterCard Worldwide, told NBC News it has not taken a position on the issue.

?No one knows how checkout fees will work their way through the system,? Wexler said in an email statement, ?but the settlement provides sufficient consumer protections while the process plays out.?

What about disclosures?

The advocacy group Consumer Action has published a booklet on credit card checkout fees. It warns shoppers to be on the lookout for these fees and advises them to express their dissatisfaction.

?Customers shouldn?t stand for it,? said Ruth Susswein Consumer Action?s deputy director of national priorities. ?Our advice is to tell them you don?t like the fee and this makes you want to take your business elsewhere.?

The new rules from Visa and MasterCard require retailers who apply a credit card surcharge to post a notice at the store?s entrance. The exact percentage of the surcharge does not need to be disclosed until the point of sale. The customer receipt must list the amount of the surcharge.

Online stores with a surcharge will not be required to have a notice on the home page. They only need to alert shoppers about this when they reach the page where credit cards are first mentioned. In most cases, that means the final step of checkout when the purchase is being completed.

Not the end of this story

The settlement that allows merchants to impose a credit card surcharge is only preliminary. The court has yet to issue its final ruling in this case. That?s expected later this year.

Once that happens, various retailers and business groups plan to challenge the settlement. That could drag into late 2014.

The possibility that the settlement could be modified will probably keep most businesses of any size from instituting credit card fees for the time being.

Randomness: Poll of quantum physicists shows agreement, disagreement and something in between

Poll of quantum physicists shows agreement, disagreement and something in between

By Tom Siegfried

Web edition: February 20, 2013

Science is not a democracy. Nature?s laws are not subject to the whims of popular vote. A scientific theory succeeds by providing logical explanations for puzzling phenomena and making correct predictions about the outcomes of new experiments. It doesn?t matter how many scientists believed in the theory beforehand (or even afterward, for that matter).

In fact, revolutionary new theories are seldom very popular. As Max Planck, the founder of quantum theory, once noted, sometimes a theory doesn?t get widely accepted until its opponents die. Nevertheless, in certain scientific matters it?s worth knowing what most experts think. Sometimes the math is clear, and experimental results indisputable, but their implications are charged with ideological controversy. Mainstream expert judgment on such matters usually offers a better path to wisdom than wishful thinking based on philosophical predisposition.

Yes, all the above could be alluding to climate change. But quantum mechanics, the math of the microworld, is more fun and less likely to elicit hate mail. And a new paper has provided actual data about what mainstream quantum physicists think about how to interpret their math.

It?s curious. It has been more than 80 years since the mathematical framework of quantum mechanics was formulated. It has been about three decades since the first modern experiments confirmed the most outrageous consequences of quantum math. Yet physicists still argue about it, some contending that the onetime consensus interpretation (named for Copenhagen, where the Danish physicist Niels Bohr developed it), should be abandoned. But apparently the Copenhagen interpretation still gets more support from experts than any of the alternatives.

It?s not easy to concisely describe the Copenhagen interpretation, but it essentially contends that reality at the atomic level is ill defined. An electron has no actual ?real? position, for instance, until a measurement determines where it is. And its location cannot be predicted precisely???you can compute only probabilities for where it will be. Electrons can be either waves or particles depending on the nature of the experimental apparatus used to observe them. In other words, for some things in the subatomic world there?s no preexisting objective reality independent of observation. Or something like that.

Einstein rejected these ideas, proclaiming that God doesn?t play dice and that the moon exists whether or not a mouse is looking at it. But he didn?t have much of a case. At a conference of quantum physicists (plus a few philosophers and mathematicians) held last year, 64 percent of 33 respondents to a questionnaire declared that Einstein was wrong. None said he was correct. A few suggested he might turn out to be right someday, and others said ?we?ll just have to wait and see.?

As for Bohr?s views, 27 percent said he was wrong, 30 percent said he was correct or ultimately would be and 30 percent voted for waiting and seeing. When asked to name their favorite interpretation, 42 percent said Copenhagen, far more than any of the other choices.

And 64 percent of the respondents concurred with the statement that randomness is a fundamental concept in nature, about half agreeing that randomness is irreducible???there is, in other words, no way to explain reality without it.

One proposal to eliminate God?s dice throwing, known as Bohmian quantum mechanics for the physicist David Bohm, was preferred by no one.

Another interpretation, championed by some experts, is the many worlds interpretation. An observation doesn?t fix an electron?s position from among multiple possibilities, this view holds. Rather an observation sends the observer off into one branch of the universe corresponding to one result, while all the other possibilities are equally real in other branches. This interpretation got 18 percent of the votes in the survey, conducted by physicists Maximilian Schlosshauer, Johannes Kofler and Anton Zeilinger and reported recently in a paper online at arXiv.org.

Of course, such surveys are mostly just for fun???the views of a particular group of experts at one conference don?t necessarily reflect the entire quantum physics community. What?s more interesting than the numerical results is their diversity. Quantum physics remains, after decades of debate, one of the most baffling theories science has ever produced. Knowledgeable people cannot agree on what to make of it. They can?t even agree on whether it matters to agree. (A favorite slogan of many physicists encountering such discussions is ?shut up and calculate.?)

But it appears that the arguments have in fact been fruitful. Efforts to probe the foundations of quantum physics beginning about three decades ago produced a new strain of quantum research called quantum information theory. It has not only illuminated quantum philosophy but has also led to potential practical applications, from crack-proof secret codes to powerful new breeds of computers and communications systems.

So it?s probably good for quantum people to continue probing their discipline?s foundation. They might uncover some new inventions, or dig up some fuel for even more controversy.

Nvidia GeForce GTX Titan


When Nvidia launched the Nvidia GeForce GTX 680 nearly a year ago, it announced that the GK104 GPU that powered the video card was the first in a series of new parts. Last November, the company took the wraps off the GK104's big brother, the GK110. The GK110 was designed for supercomputers and deployed as the Tesla K20 / K20X. Today, GK110 comes to Nvidia's high-end consumer business as the Nvidia GeForce GTX Titan. This $1,000 single-GPU card packs seven billion transistors, 6GB of RAM, and 2,688 shader cores. That's significantly larger than the Nvidia GTX 680, which packs 1,536 cores and 2GB to 4GB of RAM depending on the card model.

In the past, Nvidia's workstation and supercomputing products (Quadro and Tesla) have used the same silicon as the company's consumer graphics products. This is the first time Nvidia has brought a specialized niche product over to the general consumer market, even if the $1,000 price tag puts this well out of reach for the majority of buyers.

Design and Features

Not all Tesla-class features are enabled on Titan; the new card lacks the K20/K20X's support for dynamic parallelism, Hyper-Q, and GPU virtualization. The one capability it keeps is the option to perform double-precision floating point math at the full rate of 1.48TFLOPS per second. The GTX 680, in contrast, offers just under 192GFLOPS per second of double-precision floating point. That's not an important metric for games, but it expands the potential audience for the card?Tesla cards with this capability cost $2,500 and up.

The GTX Titan doesn't replace Nvidia's current $1,000 card, the Nvidia GeForce GTX 690, but is meant to sit beside it. The two cards are fundamentally different?the GTX 690 combines two GTX 680's in SLI on a single circuit board with a 2GB frame buffer for each GPU. The GTX Titan is a single-GPU product with more memory bandwidth (288.4GBps compared with 192.25GBps per GPU on the GTX 690) and 6GB of video RAM.

Which card is faster will depend on how well the game is optimized for SLI and how much video RAM it uses. Well-optimized games that fit within a 2GB frame buffer may be faster on the GTX 690, while titles that don't scale as well or have higher memory footprints are likely to be faster on the GTX Titan.

Nvidia GeForce GTX Titan

Performance

We tested Nvidia's latest card using an Intel Core i7 3770K Ivy Bridge CPU, 16GB of DDR3-1600 memory, a 256GB OCZ Vector solid-state drive (SSD) , and a 27-inch Asus VG278HE monitor at 1,920-by-1,080 resolution. All of our real-world game tests were run with 8x MSAA enabled, 16x Anisotropic filtering, and High Quality texture filtering.

The Titan is significantly faster than Nvidia's previous single-GPU solution, the GTX 680 or the AMD Radeon 7970 GHz Edition. In 3DMark 11's Extreme Preset, the GTX Titan's score of 4948 is nearly half again as fast as the GTX 680's 3,381 or the Radeon 7970 GE's 3,106. In the brand-new Futuremark test Fire Strike Extreme, the Titan hits 4,475, compared with 3,155 and 3,076 for the Nvidia 680 and Radeon 7970, respectively.

Real-world performance mirrors these results. In Civilization V's Late Game View benchmark test, the Radeon 7970 GE and GTX 680 trade shots at 77 frames per second (fps) and 81 fps, respectively. The GTX Titan, meanwhile, establishes its own weight division at 111 fps. In Batman: Arkham City, the Radeon 7970 pulls ahead of the GTX 680 (96 vs. 84 fps) but doesn't come close to the GTX Titan's 111.

In Shogun 2 and Metro 2033, the Radeon 7970 GE loses to the GTX 680 in feudal Japan (51 to 58 fps) but wins the battle for Russia's frozen subway tunnels (31 vs 31 fps). The GTX Titan sneers at both cards, and turns in frame rates of 83 fps and 46 fps, respectively).

Nvidia's goal with the GTX Titan was to deliver the smoothest possible game experience as opposed to the highest frame rate. They've succeeded. While we didn't have a GTX 690 to test, it's an established fact that splitting the graphics load between two cards can result in uneven frame times. This creates visible split-second stuttering on screen as the graphics card struggles to keep both frames running smoothly.

The Titan avoids this problem. Its single GPU is easily the most powerful graphics processor any company has ever fielded. Power consumption is also excellent?our testbed idled at 74 Watts when equipped with the GTX Titan, compared to 78W with the Nvidia GTX 680 and 82W with a AMD Radeon 7970 GE. Load power was similarly excellent?the Titan topped out at 320W compared with 250W for the Nvidia GTX 680 and 300W for the AMD Radeon 7970 GE.

With all that said, should you scamper out and buy one? The answer to that is a bit complex. The GTX Titan's price/performance ratio isn't as good as that of the GTX 680; it offers 35% to 50% improved performance but for twice the price. Strictly in terms of performance-per-dollar, the GTX 680 or Radeon 7970 GE are still a better deal. On the other hand, if you're a programmer who wants to take advantage of the GTX Titan's 1.48 TFLOPs of double-precision floating point, the GTX Titan is a fabulous deal. This card packs all the floating-point performance of a high-end Tesla for more than a $1,000 less.

Customers who prefer to buy high-end hardware on a three-to-four-year replacement cycle should also seriously consider the GTX Titan. The card's 6GB of VRAM will be current for years. Ditto for the huge amount of memory bandwidth and Kepler's already-excellent performance characteristics. The GTX Titan really is an early adopter product?buy one now, and you'll be ahead of the mainstream for several years.

If you're into multi-monitor gaming, the GTX Titan is an easy fit there, too. While we don't have comparative figures for other solutions, the GPU has no trouble driving 5,760-by-1,080 resolutions across three 27-inch displays. That means it'll also have no trouble driving single monitors at 2,560-by-1,440, and could likely handle even a 4K HDTV with aplomb.

If the Nvidia GeForce GTX 680 was Nvidia's response to a resurgent AMD 12 months ago, the Nvidia GeForce GTX Titan cements Team Green's position in the driver's seat. If you've got the cash, this card is an easy recommendation and is our new Editors' Choice for high-end video cards.

The Humane Society of the United States and Jana Kohl Urge Kohl's ...

February?20,?2013

The Humane Society of the United States and Dr. Jana Kohl, granddaughter of the founder of Kohl?s, are urging Kohl?s Corporation to go fur-free in its department stores. The HSUS submitted a shareholder resolution asking Kohl?s to create a policy clearly stating the company?s future plans for banning animal fur sales. Such a policy would help protect Kohl?s customers from misleading fur labels and advertisements, and move the company away from the inhumane treatment of animals killed for their fur.

?In the last two years, Kohl?s has made a number of vague and confusing statements to customers and shareholders pertaining to its sales of animal fur," said P.J. Smith, corporate outreach manager of the fur-free campaign for The HSUS. "The Humane Society of the United States is asking Kohl?s to be consistent with its statements about animal fur and move away from an unnecessary and inhumane product, especially because so many faux fur alternatives are available.?

Among the confusing statements Kohl?s has sent to customers and shareholders about its fur sales since 2011:

  • "We do not intend on discontinuing our minimal use of fur? ??????????
  • ?We typically do not carry merchandise made of animal fur?
  • ?We carry a minimal amount of merchandise using fur; however, occasional seasonal items use fur accents?
  • ?All merchandise and related packaging must be free of any real animal fur unless expressly requested and authorized in writing by Kohl?s?

Ironically, Kohl?s ?Kohl?s Cares? scholarship competition rewarded a boy who contributed to his community by organizing petitions and handcrafting bracelets and key chains to raise awareness about the cruel fur trade. The contradiction between this action and recent statements is misleading to Kohl?s customers, leaving the potential for selling animal fur in the future. By not committing to a fur-free policy, Kohl?s customers are at continued risk of being deceived.

Kohl said, ?It brings me great sadness that my family name is now associated with the fur business, an industry marked by such barbaric cruelty against animals that it's nothing short of legalized torture. I call on Kohl's to be a corporate leader, showing concern for the environment, social responsibility and humane practices. I urge them to set an example for other corporations to begin to repair our world before it's too late."

Many retailers and designers have agreed to phase out the sale of animal fur products because of the inhumane treatment of animals, and false labeling and advertising that have consistently plagued the retail industry. Lack of transparency and quality control in the fur industry puts Kohl?s and its customers at continued risk of being duped and associated with animal cruelty.

Facts:

  • More than 300 retailers, designers and brands, including JCPenney, Forever 21, Liz Claiborne, Urban Outfitters, Gap, J. Crew, Overstock.com, Tommy Hilfiger, and Calvin Klein have committed to being fur-free and are included on The HSUS' fur-free list.
  • The HSUS has consistently found falsely-advertised and falsely-labeled animal fur garments that mislead customers. In recent years, misrepresentation of fur products has led to dozens of companies being named in petitions filed before the Federal Trade Commission, a lawsuit before the D.C. Superior Court and multiple media stories about sales representatives misrepresenting animal fur to reporters posing as customers.
  • Millions of animals, including foxes, rabbits, raccoon dogs, domestic dogs and cats, mink and coyotes, are killed every year by the fur trade.
  • Environmental concerns associated with animal fur include threatened and endangered species caught or killed in traps, feces and urine from massive cage operations entering and contaminating waterways, and tanning processes that involve carcinogenic chemicals.
  • Animals on fur factory farms spend their entire lives crammed in wire cages, often exhibiting neurotic behaviors like constant spinning and pacing. Foxes can never touch soil, much less dig, and semi-aquatic mink have no access to swimming water.
  • Several countries, including the Netherlands, and the United Kingdom, have passed legislation to phase out fur farming because of inhumane practices. Killing methods on fur factory farms include anal and genital electrocution, neck breaking, gassing and poisoning, and the practice of live skinning has been documented in China.
  • In the wild, some terrified and injured animals caught in steel-jaw leghold traps try to escape by chewing off their own limbs. In some states, trappers are not required to check traps for several days, leaving animals to suffer in agony. When trappers do return, they often kill the animals by beating, stomping or shooting them in the head. Many countries and several U.S. states have banned or severely restricted the steel-jaw leghold trap.
