Gonorrhea is about to become impossible to treat


Gonorrhea has taken many forms over the last few decades. The strain that people acquire today isn't the same one that previous generations had to deal with. In fact, it might not be the same strain that infected people a little over 10 years ago.

New class of antibiotics discovered by chemists


A new class of antibiotics to fight bacteria such as methicillin-resistant Staphylococcus aureus and other drug-resistant bacteria that threaten public health has been discovered by a team of chemists. The new class, called oxadiazoles, was discovered in silico (by computer) screening and has shown promise in the treatment of MRSA in mouse models of infection.

How sound affects the taste of our food


High-frequency sounds enhance the sweetness in food, while low frequencies bring out the bitterness. So could sound replace sugar? And what kind of music should restaurants play?

Dropped your toast? Five-second food rule exists, new research suggests


Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time, according to new research. The findings suggest there may be some scientific basis to the '5 second rule' -- the urban myth about it being fine to eat food that has only had contact with the floor for five seconds or less.

Chimpanzees Can Play Video Games Better Than Kindergartners


Look out, gamers: chimpanzees might be coming for your high scores. Panzee, a 22-year-old female chimp, significantly outperformed 12 children and 4 adults on a complex maze in a virtual-reality computer game.

Researchers pitted four adult chimps against twelve human children ranging from 3 to 12 years old, and four adult humans.

Empathy chimpanzees offer is key to understanding human engagement


New findings show that chimpanzees exhibit flexibility in their empathy, just as humans do. This may help explain the evolution of how and when humans engage with others and choose to offer flexibility, and how we can do so more.

Chimps put people ahead of baboons


Chimpanzees that have had positive experiences with humans appear to trust people more than they do baboons and unfamiliar chimps, a new study suggests.

The findings, published in the latest Proceedings of the Royal Society B, indicate that chimpanzees can learn to bond and exhibit empathy for members of another species, such that trust develops even at the subconscious level.

Bold or anxious baboons learn to solve tasks from other baboons


Baboons learn from other baboons about new food sources -- but only if they are bold or anxious. The results suggest that personality plays a key role in social learning in animals, something previously ignored in animal cognition studies. Researchers examined how personality influenced whether baboons solved foraging tasks and whether they then demonstrated to others how to solve the tasks. They found bolder baboons did both.

Secret to Ancient Sloths' Aquatic Lives Found


Millions of years ago, aquatic sloths roamed shallow waters off the coast of modern-day Chile and Peru. These now-extinct swimmers had highly dense bones that facilitated their transition from land to sea by helping them sink to seafloors to graze on vegetation, according to a new report.

Only two groups of sloths exist today, both of which live in trees and grow to be the size of small monkeys.

Posh Dog Outfit from China's 'Forbidden City' Revealed


While President Barack Obama has Bo and Sunny, and President George W. Bush had Barney and Miss Beazley, a newly published tale of a dog that lived in China's Forbidden City more than a century ago reveals this pup's lifestyle easily outdid that of any presidential pooch.

Peru tells Machu Picchu tourists to keep their clothes on


Peru has increased surveillance at popular archeological sites to counter a new trend of tourists taking nude photos at Machu Picchu.

Tourists have been posting the naked pics on blogs, prompting a statement from the cultural ministry rejecting “any disrespectful act committed by visitors” to the historical sites.

Archaeological Storehouses Looted in Syria


Storehouses with more than twenty years' worth of finds from an archaeological dig in Syria have been ransacked amid the ongoing civil war, researchers say.

Archaeologists from Leiden University in the Netherlands had been excavating the ancient mounds at the northern Syrian site of Tell Sabi Abyad since 1986. The abrupt onset of war forced them to stop their research in 2011.

Petra monuments orientated according to celestial events


During the winter solstice, the sun is filtered into the Monastery at Petra, Jordan, illuminating the podium of a deity. Just at this moment, the silhouette of the mountain opposite draws the head of a lion, a sacred animal. These are examples from a study where researchers from Instituto de Astrofisica de Canarias and CSIC (Spain) showed how celestial events influenced the orientation of the great constructions of the Nabataeans.

Light pollution impairs rainforest regeneration


Increasing light pollution in tropical habitats could be hampering regeneration of rainforests because of its impact on nocturnal seed-dispersers.These new findings were reported by scientists from the German Leibniz Institute for Zoo and Wildlife Research Berlin (IZW).

Sensor Turns Faintest Radio Waves into Laser Signals


Physicists have found a way to detect faint radio waves and convert them directly into signals that can be transmitted by fiber optics. The discovery could improve the sensitivity of detectors used in magnetic resonance imaging and radio astronomy, and help to connect future quantum computers into a network.

Spider Silk Poised For Commercial Entry


There is a scene in the film “Spider-Man 2” where Spider-Man prevents a train full of people from crashing by holding it back with about 10 sets of spider silk ropes each less than half an inch thick. It turns out the scene isn’t just fantasy.

Crystals Ripple in Response to Light


Light can trigger coordinated, wavelike motions of atoms in atom-thin layers of crystal, scientists have shown. The waves, called phonon polaritons, are far shorter than light waves and can be "tuned" to particular frequencies and amplitudes by varying the number of layers of crystal, they report in the early online edition of Science March 7.
