When faced with a challenging situation, a bicultural person may decide how to respond based on the cultural mindset that is active at the time, researchers have concluded.
College students in Hong Kong, for example, who were prompted ahead of time with icons of Chinese culture were more likely to cooperate with friends than were students who had been cued with American cultural icons, according to Ying-yi Hong of the University of Illinois at Urbana-Champaign.

A compound derived from cottonseed could help improve the effectiveness of chemotherapy at treating head and neck cancer, researchers at the University of Michigan Comprehensive Cancer Center have found.
The findings, which appear in the July issue of the journal Molecular Cancer Therapeutics, could lead to a treatment that provides an effective option to surgically removing the cancer, helping patients preserve vital organs involved in speech and swallowing.
While ne
An extremely rare “royal” turtle narrowly escaped a trip to a Chinese soup-pot, thanks to a tiny microchip implanted in its skin, according to experts from the New York-based Wildlife Conservation Society (WCS), who rediscovered the species four years ago in Cambodia.
Wildlife inspectors discovered the 33-pound (15 kg) turtle in a crate of confiscated wildlife in Vietnam, where smugglers planned to send the shipment on to China. The inspectors used a special reading device to de
The tongue’s ability to differentiate between sweet and bitter tastes may reside in the same taste bud cells, a new study reports.
The study explains the discovery of a chemical messenger called neuropeptide Y (NPY) in taste bud cells. Though researchers have long known that NPY is active in the brain and gut, this is the first study to show that it is also active in taste bud cells.
That finding gives scientists a deeper understanding of how the human brain may distinguis
High throughput method is very versatile, signals a new era for NMR
University at Buffalo scientist created a stir in 2003 when he announced a much faster, more precise and far less expensive method of obtaining nuclear magnetic resonance (NMR) data to map a protein’s atomic structure. Genomics researchers were fascinated, but some also were a bit skeptical.
Not anymore.

About 13% of bacteria near the ocean’s surface contain proteorhodopsin, a membrane protein able to harness sunlight’s energy, according to a new study by Oded Beja and colleagues in the open-access journal PLoS Biology. Given the dearth of nutrients in their environment, these oligotrophic bacteria must generate their energy from a variety of sources. The study reveals that proteorhodopsin is uniquely suited to capturing the high-radiation sunlight that illuminates the sea. Through
If necessity is the mother of invention, the coevolutionary arms race is the mother of adaptation. For parasites and hosts engaged in an ongoing battle to gain advantage, those adaptations take many forms. In a new analysis in the premier open access journal PLoS Biology, Stephanie Bedhomme, Yannis Michalakis, and colleagues extend traditional methods of studying the coevolution of parasite virulence and host life history traits by introducing an additional variable: intraspecific competition betwe
Lives and money could be saved if co-pays for ACE inhibitors were eliminated
Nothing in life is free, the old saying goes. But maybe some things should be, according to a new University of Michigan Health System study. Specifically, researchers find, a group of medicines called ACE inhibitors should be available at no cost to the 8 million Americans over age 65 who have diabetes. These drugs are so beneficial for these patients that even giving them away ultimately would save
A therapeutic approach for battling cancer that is based on infection with a specially designed virus similar to the one that causes the common cold has shown promise in clinical trials. Now, new research suggests that fever might be a useful weapon in the fight as well. The study, published in the July issue of Cancer Cell, demonstrates that tumor cells are even more sensitive to viral therapy after they have been incubated at an elevated temperature. The findings could have a significant impact on
University of Michigan researchers have figured out one more component in cancer cells’ aggressive growth—and hope that knowledge can help kill the cells.
In the July issue of Cancer Cell, the scientists explain how cancer tumor cells attach themselves to a protein on the surface of cells lining blood vessel walls. When this attachment happens, it tells the cancer cell to grow and develop blood vessels, which feed the cell. Cun-Yu Wang, senior author on the paper, said this
A futuristic design by Faber Maunsell and Hugh Broughton Architects has won the competition for the new British Antarctic Survey (BAS) Halley Research Station. In a very close-run contest, three finalists presented their ideas to a Jury Panel, technical advisory panel and BAS scientists.
Director of BAS, Professor Chris Rapley, CBE said, ‘This was an incredibly tough choice for the Jury Panel to make. We were presented with three outstanding schemes – each one of them creating

Solar concentrators using highly efficient photovoltaic solar cells will reduce the cost of electricity from sunlight to competitive levels soon, attendees were told at a recent international conference on the subject. Herb Hayden of Arizona Public Service (APS) and Robert McConnell and Martha Symko-Davies of the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) organized the conference held May 1-5 in Scottsdale, Ariz.

Cornell University scientists have developed a rapid, less costly and sensitive new technique for detecting group A streptococcus, the bacteria that cause scarlet fever. Details will be announced today at the Institute of Food Technologists Annual Meeting and Food Expo in New Orleans.
The presentation by Sam Nugen, a graduate student in Cornell’s food science department, will focus on detecting the food-borne bacteria Streptococcus pyogenes (S. pyogenes), but the technique
University of Queensland researchers have identified a protein that is crucially involved in how our memories are stored and processed, paving the way for new strategies to treat conditions certain mental disorders.
Dr Louise Faber and Professor Pankaj Sah, from UQ’s Queensland Brain Institute (QBI), have been studying how cells in the brain form memories.
“What we were looking at in particular is how the memory of emotions, such as fear and anxiety, are laid dow
Brisbane researchers are hoping to prove the dangers of shaking babies by creating a model that will show how quickly babies can be injured.
The University of Queensland research team of civil engineers and a child health expert is working on a numerical model that will tell when a baby’s brain could be damaged by violent shaking.
Shaking can cause Shaken Baby Syndrome which swells a baby’s brain and triggers internal bleeding.
