Avian influenza survivors' antibodies effective at neutralising H5N1 strain

...ses in humans, 185 of them fatal. Now, doctors based at the Hospital for Tropical Diseases in Ho Chi Minh City, Vietnam, the Institute for Research in Biomedicine in Bellinzona, Switzerland and the National Institute of Allergy and Infectious Diseases in Bethesda, US, have shown that monoclonal antibod...

New research shows sharks use their noses and bodies to locate smells

...uilibrium problems in humans, senses that are also based on hair cells. Sharks with their lateral lines intact demonstrated a preference for the odor plume over the seawater plume and, more specifically, for the odor source with the higher turbulence (the brick on the odor side) over the source of the ...

Mule deer moms rescue other fawns

...tivation for looking out for other fawns is likely based not on altruism but on simple survival, said Lingle. "Having a rigid and aggressive response to the simple sound of a fawn distress call may ensure effective defence of a female's own offspring, even though this means the female invests time and e...

Climate change was the cause of Neanderthal extinction in the Iberian Peninsula

...oved. Climate reconstructions The study is based upon climate reconstructions elaborated from marine records and using the experience of Spanish and international research groups on Western Mediterranean paleoceanography. The conclusions point out that Neanderthal populations did suffer fluctuation...

Machine preservation may promote more organ sharing

...ients receiving kidneys from older deceased donors based on whether organs were preserved by pump or cold storage. "The critical organ shortage poses a challenge to optimize the use and function of all organs from deceased donors," said Stratta, explaining why it is important to compare the two methods ...

Madagascan tropical forests return thanks to better management and well-defined ownership

LIAI scientists make important finding on cytomegalovirus transmission

... the immune system. The research team’s findings, based on controlled laboratory studies of mice, may also have implications for other chronic virus infections, such as hepatitis and HIV, the virus that causes AIDS. The team’s findings were published online this week in the Journal of Experimental Medic...

'Short-circuit' found in ocean circulation

...ational Oceanography Centre, Southampton (formerly based at the University of East Anglia), has discovered a 'short-circuit' in the circulation of the world's oceans that could aid predictions about future climate change. This process in the Southern Ocean allows cold waters that sink to the abyss to r...

Study offers clues to 'Broken Heart Syndrome'

...edications to support blood pressure." In fact, based on symptoms, electrocardiographic (ECG) tracings, and blood tests for heart damage, it often seems as if the patient is having a heart attack. The mystery deepens in the cardiac catheterization laboratory, when the interventional cardiologist finds n...

HIV survival improves if patients stay in care

.... Researchers divided the men into four groups based on the number of quarters in the first year after starting treatment that they visited their HIV physicians or health care provider. Sixty-four percent of them had at least one visit in all four quarters, 18 percent in three of four quarters, 11 perc...

DNA-damage test could aid drug development

...techniques from an established cell-culture system based on mouse fetal liver cells to create a new system based on adult red cell precursors from mouse bone marrow. Shuga patiently optimized the system, which all...

Latent memory of cells comes to life

...ell-generations. By building a mathematical model based on positive feedback from the microscopic state of the nucleosomes, the research group could simulate the experimental results and in this way gained insight into the mechanisms by which living cells with identical DNA can achieve extreme differentia...

No magic tomato? Study breaks link between lycopene and prostate cancer prevention

...emiology, Biomarkers & Prevention, researchers based at the National Cancer Institute and Fred Hutchinson Cancer Research Center report that lycopene, an antioxidant predominately found in tomatoes, does not effectively prevent prostate cancer. In fact, the researchers noted an association between bet...

DNA analysis suggests under-reported kills of threatened whales

... Using their "capture-recapture" model, which is based on statistical probability, the researchers estimate that the true number of minke whales that likely passed through Korean markets from 1999 to 2003 was probably 827 individuals, or nearly twice the number in official reports. "If the mortality i...

Study of protein folds offers insight into metabolic evolution

...among the earliest catalysts of life. This idea is based in part on the observation that RNA still retains many of its catalytic capabilities, including the ability to make proteins. Gradually, according to this theory, proteins began taking over some of the original functions of RNA. "The most ancient ...
