ASU research shows connection between testosterone, dietary antioxidants and bird coloration

...They also act as an antioxidant in the body, which improves immune system function. “Researchers in animal behavior often study what keeps sexual signals like bright colors or elaborate songs ‘honest,’ or why all individuals cannot produce them ad nausea and try to get mates,” said McGraw. “The reason typ...

Study investigates 'divorce' among Galapagos seabirds

...est. The chance of successfully breeding probably improves as the pairs of birds get older and are together longer, as has been found in other birds. But, often the female seeks a divorce after a few breeding seasons. Since males significantly outnumber females in the colony studied, there are plenty of...

Pistachios lower cholesterol, provide antioxidants

...ich may indicate that the lutein in pistachio nuts improves the risk of cardiovascular disease by reducing serum oxidized LDL. "Our study has shown that pistachios, eaten with a heart healthy diet, may decrease a person's CVD risk profile," says Dr. Penny Kris-Etherton, distinguished professor of nutrition...

Fat screen delivers plant-derived chemical with antidiabetic effects

...oth promotes fat cell differentiation in vitro and improves glucose tolerance in vivo," Tontonoz's team concluded. The biological activities of harmine and TZDs underscore the fact that links between fat tissue and insulin resistance are complex and are likely to involve not only changes in fat tissue differe...

Warts vaccine -- 1 of many in pipeline

... has so far proven safe, and we want to know if it improves the outcome after conventional therapy, which all patients also receive," Dr Jardine said. Trial researchers aim to use a tweaked version of Professor Frazer’s cervical cancer vaccine to treat genital warts. Professor Frazer said this vaccine ...

Researchers develop way to calculate speed of bacterial sex

...he environment. Researchers believe this new model improves upon existing models by taking into account characteristics of the natural subsurface environments, the typical bacteria hangouts. This model will help scientists to quantify the spread of important bacterial traits. The swapping of genetic material...

Noise echoes in cell communications

...Rutgers-Camden research team's mathematical theory improves previous knowledge by offering a single explanation of the properties of noise in hearing under different conditions. To develop the theory, Hong used a variation on the wavelet technique, which he says is responsible for clarifying the JPG image. T...

Helium helps patients breathe easier

...hyperoxia (40 per cent oxygen, 60 per cent helium) improves the exercise tolerance of COPD patients to a greater extent than oxygen alone, which is currently used for treating patients with this disorder. People with severe COPD typically struggle for every breath while exercising and any improvements that co...

Action video games sharpen vision 20 percent

...almology clinics. In essence, playing video game improves your bottom line on a standard eye chart. "Action video game play changes the way our brains process visual information," says Daphne Bavelier, professor of brain and cognitive sciences at the University of Rochester. "After just 30 hours, players...

Sunshine pill for prostate cancer in 2009

...e up with the idea because vitamin D from sunlight improves the prognosis of certain cancers. But taking natural levels of the vitamin has no effect. Novacea, the company that makes Asentar, produced a novel formulation that reproduces the healing effect without the dangerous side-effects of a vitamin D overd...

Speeding 'fingertip' discovery -- 20 years of protein info in 1 place

...on their mass - their size and weight. The process improves on previous techniques by breaking up proteins more gently and keeping chemical modifications like phosphorylation intact. Previous spectrometry methods were “just too rough?on the delicate protein alterations and sheared them right off, he says. “W...

Do you hear what i see?

...from. "Clearly, our acoustical understanding often improves if we can see the lips of the speaker—for example at a crowded cocktail party," he says. "However, currently it is not clear whether and how audio-visual interactions are specialized for the processing of communication signals. "The present study cle...

Adding radiation decreases breast cancer recurrence

...rmone modulating drugs, such as tamoxifen, further improves survival and reduces recurrence. Women over 65 are at the highest risk for breast cancer and make up half of those diagnosed. However, they are less likely to receive standard therapy, particularly radiotherapy after breast conserving surgery, th...

Satellites shed light on global warming

...te at which global temperatures are increasing and improves the accuracy of our climate change models and weather forecasts. "There is now evidence there is a distinctive upward trend in global sea surface temperatures, and this we can now see from measurements made from Envisat," Professor Llewellyn-Jone...

Protein therapy may reduce infarct size in heart attack patients

...e heart muscle. Restoring blood flow to the heart improves clinical outcomes in heart attack patients, but there remains significant injury to heart muscle cells. Protein kinase C (PKC) is activated in these heart cells, initiating a series of events that can cause further damage to the heart. Animal studi...

Magic Beans -- Anti-obesity soya could help prevent diabetes

...abdominal adipose tissue - so loss of weight often improves glycaemic control,?says Dr Bender. Lynne Garton, a registered dietician and nutritionist and consultant to the Soya Protein Association, said: "Soy fits in well to a healthy balanced diet which is important in preventing diabetes ?low in fat, high...

New research shows why too much memory may be a bad thing

...hat the absence of neurogenesis in the hippocampus improves working memory, a specific form of short-term memory that relates to the ability to store task-specific information for a limited timeframe, e.g., where your car is parked in a huge mall lot or remembering a phone number for few seconds before writin...

New imaging technique tracks traffic patterns of white blood cells

...annel digital fluorescence videomicropscopy vastly improves on prior intravital observations of leukocyte behavior in vivo by allowing the near-simultaneous observation of cell surface markers and microdomains." Researchers explored various mouse models including that of Sickle Cell disease which is a comm...

Virginia Tech's System X supercomputer provides super tool for simulation of cell division

...es," Watson said. "Then the local search algorithm improves the values from the starting points found by the global algorithm." The parallel computer programs can now be used by others for similar problems. "The parameters found for the budding yeast cell cycle model are good until the next scientist inval...

Radiation after surgery doubles survival time for some lung cancer patients

...d found that additional chemotherapy after surgery improves overall survival in cancer that has spread to the lymph nodes. In this study, radiation was not randomized nor mandatory but only recommended for patients whose disease had spread to the lymph nodes. 232 lung cancer patients received radiation after ...
