In daily life we remember faces and voices of several known individuals. Similarly, mammals have been shown to remember calls and faces of known individuals after a number of years. Markus Boeckle and Thomas Bugnyar from the Department of Cognitive Biology of the University of Vienna show in their recent article, published in Current Biology, that ravens differentiate individuals based on familiarity. Additionally, they discovered that ravens memorize relationship valence and affiliation. So far it was unknown whether relationship valence can be remembered based on former ...

The radiata pine is the tree species par excellence in the Basque Country's forests. Like other types of pine, the lack of water is one of the factors having the greatest effect on its survival and productivity. Until now, the Basque Country's high, steady rainfall has encouraged the cultivation and good productivity of this species. This situation could change over the coming years if, in line with the predictions of climate change, average temperatures rise and droughts become more frequent and intense. So, new varieties of the radiata pine that are more resistant to ...

CAMBRIDGE, Mass. — Every year, more than a million Americans receive an artificial hip or knee prosthesis. Such implants are designed to last many years, but in about 17 percent of patients who receive a total joint replacement, the implant eventually loosens and has to be replaced early, which can cause dangerous complications for elderly patients. To help minimize these burdensome operations, a team of MIT chemical engineers has developed a new coating for implants that could help them better adhere to the patient's bone, preventing premature failure. "This would ...

COLUMBIA, Mo. – Since 1992, the government's Back-to-Sleep Campaign has encouraged parents to place infants on their backs to sleep. Still, more than 4,500 infants die unexpectedly during sleep each year in the United States. Now, a University of Missouri injury prevention researcher says that safe, separate sleep environments for infants are critical to preventing sudden unexpected infant deaths (SUIDs). "Many of these SUIDs are due to unsafe sleep environments, and these deaths are totally preventable," said Patricia Schnitzer, an associate professor in the MU Sinclair ...

WASHINGTON, April 19, 2012 — Just in time for Sunday's celebration of Earth Day, the American Chemical Society (ACS) today released a video revealing the journey that recyclable materials take beyond those blue curbside bins. In the latest episode of ACS' award-winning Bytesize Science series, viewers take a tour of a typical recycling center to see how these facilities sort the mountains of recyclables they receive every day. The video is available at www.BytesizeScience.com. It points out that the average American generates about 4.5 pounds of trash every day. That's ...

WASHINGTON, April 19—To produce the maximum amount of energy, solar cells are designed to absorb as much light from the Sun as possible. Now researchers from the University of California, Berkeley, have suggested – and demonstrated – a counterintuitive concept: solar cells should be designed to be more like LEDs, able to emit light as well as absorb it. The Berkeley team will present its findings at the Conference on Lasers and Electro Optics (CLEO: 2012), to be held May 6-11 in San Jose, Calif. "What we demonstrated is that the better a solar cell is at emitting photons, ...

As any city dweller knows, buses are rarely on time. It's typical to wait a while, only to have several buses show up one after another – a phenomenon known as bus bunching. Fortunately, researchers and students at the Georgia Institute of Technology have developed a possible solution for bus bunching that provides better service to riders, simplifies the job of drivers and reduces work for management. Industrial & Systems Engineering Professor John Bartholdi and Georgia Tech alumnus Don Eisenstein (MS IE 1983, PhD IE 1992), a colleague from the University of Chicago, ...

Mount Sinai School of Medicine researchers have found that targeted swallowing exercises can help alleviate swallowing dysfunction – a debilitating side effect in people undergoing chemoradiation therapy (CRT) for head and neck cancer. The study, published in the April issue of Archives of Otolaryngology – Head & Neck Surgery, a JAMA Network publication, suggests that clinicians should consider giving all patients undergoing CRT an exercise regimen to improve their quality of life after treatment. "This study provides clear evidence that aggressive swallowing therapy ...

While white men are expected to be assertive and aggressive leaders, black men and white women are often penalized for that kind of behavior in the workplace. A new study published in Psychological Science, a journal of the Association for Psychological Science, looks at another group: black women. They find that, rather than being viewed as a combination of black men and white women, black women also seem to be expected to act assertively. "Traditionally, women have been assigned to a more subordinate role," said Robert W. Livingston of Northwestern University, who co-wrote ...

PROVIDENCE, R.I. – Are women willing to use a vaginal gel to protect themselves against HIV infection?

An international team of researchers headed by glaciologists from the University of Zurich and with the involvement of scientists from Geneva now outlines the current state of knowledge of glaciers in the Himalayas in a study published in Science. The scientists confirm that the shrinkage scenarios for ...

CHAMPAIGN, Ill. — As biofuel production has increased – particularly ethanol derived from corn – a hotly contested competition for feedstock supplies has emerged between the agricultural grain markets and biofuel refineries. This competition has sparked concern for the more fundamental issue of allocating limited farmland resources, which has far-reaching implications for food security, energy security and environmental sustainability. Numerous studies of land use, food prices, environmental impact and more have fed the so-called "food versus fuel" debate. However, according ...

DETROIT – While mood disorders like depression or anxiety tend to negatively affect treatment for allergies and chronic rhinosinusitis, the same cannot be said for patients with nasal obstructions such as deviated septum, according to researchers at Henry Ford Hospital. The new study shows mood disorders are not linked to either nasal obstructive symptoms or the failure of nasal obstruction surgery. Results also suggest that those patients with nasal obstruction caused by septal deviation – a blockage of the nasal airway caused by a portion of cartilage or bony septum ...

Having a new baby brings much joy to a new family. But for a family whose baby cries for hours on end, fusses through feedings, or has difficulty sleeping, the joy may be overshadowed by feelings of helplessness and frustration. The treatment of that infant – and that family – will impact the parent-child relationship for years to come. Research has recently been published in the Infant Mental Health Journal that supports an integrated model of care that is found at the Infant Behavior, Cry and Sleep Clinic at the Brown Center for the Study of Children at Risk at Women ...
