In a finding that may potentially improve survival from war injuries and disasters, laboratory researchers report that refrigerated whole blood may have a shelf life well beyond the current standard of 24 to 48 hours.

A study by Rimma Teper, Michael Inzlicht, and Elizabeth Page-Gould of the University of Toronto Scarborough (UTSC) on human morality has just been published in Psychological Science, a journal of the Association of Psychological Science.

The study tested the difference between moral forecasting and moral action—and the reasons behind any mismatch. The findings look encouraging: people act more morally than they would have predicted.

With most people unable to get enough vitamin D from sunlight or foods, scientists are suggesting that a new vitamin D-fortified food — bread made with high-vitamin D yeast — could fill that gap. Their study, confirming that the approach works in laboratory tests, appears in ACS' Journal of Agricultural and Food Chemistry.

Most large wind turbines currently operate at variable speeds. When the wind is strong, the rotor turns fast; when it slows down, the rotor speed drops. Typically rotors complete 12 to 16 revolutions per minute. The generator is connected to the rotor via a gearbox. Here too, the speed of rotation varies with the speed of the wind.

CLEVELAND – February 21, 2011 – New research shows that medications which have raised safety concerns over heart attack and stroke risks may not have gotten approval from the Food and Drug Administration (FDA) if the cardiovascular effects of fluid retention had been better understood. Fluid retention may explain the increased risk of heart attacks and strokes of medications such as Vioxx®, Bextra®, and Avandia®.

"The presence of two resistent forms of protozoons, the oocysts from the Cryptosporidium genus and cysts of the Giardia genus, is one of the greatest public health problems in water supply, because these parasites can easily survive our water treatment systems", José Antonio Castro Hermida, a scientist at the Galician Institute for Food Quality in the Xunta de Galicia (regional government), tells SINC.

Researchers at IRB Barcelona have completed the 3D structural sequence adopted by several essential proteins in the exchange of substances between the extra and intracellular milieu. This finding provides a global perspective of the structural changes that occur in these relevant proteins during basic cell processes, such as protein synthesis, the regulation of metabolism and cell volume, and nerve transmission.

The preliminary results of the Semporna Marine Ecological Expedition (December 2010) indicate that Semporna may have the world's highest marine biodiversity. The expedition yielded a record number of 43 species of mushroom corals. Furthermore, some new species were discovered, among which at least two shrimps and possibly a number of gall crabs. The health of the reefs was judged to be relatively poor: 36% of the transects had fair, another 36% had poor live coral cover.

Complementary and alternative medicine (CAM) is increasingly popular in maternity care, but healthcare professionals need formal evidence-based education and guidance about its use, according to a review in the March issue of the Journal of Advanced Nursing.

There is also need for greater respect and cooperation between conventional and alternative practitioners and improved communication with patients about the growing use of CAM.

Immunology: Three percent of the world's population is currently infected by hepatitis C. The virus hides in the liver and can cause cirrhosis and liver cancer, and it's the most frequent cause of liver transplants in Denmark. Since the virus mutates strongly, we have no traditional vaccine, but researchers at the University of Copenhagen are now the first to succeed in developing a vaccine, which provides future hope for medical protection from this type of hepatitis.

Researchers at the University of Illinois at Chicago have discovered a signaling mechanism in the bacterial ribosome that detects proteins that activate genes for antibiotic resistance.

"The ribosome is one of the most complex molecular machines in the cell," said Alexander Mankin, UIC professor and director of the Center for Pharmaceutical Biotechnology. It is responsible for the production of all proteins in the cell, and in bacteria it is one of the major antibiotic targets.

Rates of unintended pregnancies and abortions decrease significantly when women receive a one-year supply of oral contraceptives, instead of being prescribed one- or three-month supplies, a UCSF study shows.

Researchers observed a 30 percent reduction in the odds of pregnancy and a 46 percent decrease in the odds of an abortion in women given a one-year supply of birth control pills at a clinic versus women who received the standard prescriptions for one – or three-month supplies.

CHAMPAIGN, Ill. — Researchers have developed a simple method of making short protein chains with spiral structures that can also dissolve in water, two desirable traits not often found together. Such structures could have applications as building blocks for self-assembling nanostructures and as agents for drug and gene delivery.

Led by Jianjun Cheng, a professor of materials science and engineering at the University of Illinois, the research team will publish its findings in the Feb. 22 edition of the journal Nature Communications.

ANN ARBOR, Mich. – Doctors are increasingly using a convenient blood glucose test for diagnosing diabetes and pre-diabetes, but a study by the University of Michigan's C.S. Mott Children's Hospital shows it's not the best way to diagnose diabetes in children.

The hemoglobin A1c test has become the preferred way to diagnose diabetes among the millions of Americans who have diabetes but show no symptoms. The simple test measures longer-term blood sugar levels -- without requiring patients to fast overnight.

The active ingredient in cannabis can improve the appetites and sense of taste in cancer patients, according to a new study published online in the cancer journal, Annals of Oncology [1] today.
