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.
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.
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?
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.
Education scholar Denise Pope has found that too much homework has negative effects on student well-being and behavioral engagement.
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.
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.
Chimpanzees that have had positive experiences with humans appear to trust people more than they do baboons and unfamiliar chimps, a new study suggests.
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.
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.
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 has increased surveillance at popular archeological sites to counter a new trend of tourists taking nude photos at Machu Picchu.
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.
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.
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).
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.
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.
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.
