Philandering female felines forgo fidelity

...nging females mating with a number of males, which could be an advantage in terms of helping to maintain genetic diversity,” said ZSL’s Dada Gottelli, the study’s lead author. Findings from the study are significant for conservation efforts for the species, which is threatened by a number of human-relat...

Smallpox outbreak: How long would it take for vaccines to protect people? Would it work?

... getting vaccinated following exposure to smallpox could provide protective effects. For example, for the flu vaccine to work, people need to get vaccinated before being exposed to influenza. The currently licensed smallpox vaccine, however, provides benefits post-exposure, and may be useful in further pre...

Hawaiian treasure, macadamia nuts good for the heart

...es of fat and protein in the diet. For example, we could switch skim milk for 2 percent milk and add some macadamia nuts." Macadamia nuts are native to Australia, but were imported to Hawaii and thrived. The first commercials crop of Hawaiian macadamia nuts was harvested in 1956. ...

Pistachios lower cholesterol, provide antioxidants

...ased levels of antioxidants provided by pistachios could reduce inflammation and oxidation," says Gebauer. Pistachios contain more lutein, ?normally found in dark leafy vegetables -- beta carotene ?a precursor to vitamin A ?and gamma tocopherol ?the major form of vitamin E ?than other nuts. It is oxidize...

Arctic ice retreating more quickly than computer models project

...climate model projections. As a result, the Arctic could be seasonally free of sea ice earlier than the IPCC- projected timeframe of any time from 2050 to well beyond 2100. The authors speculate that the computer models may fail to capture the full impact of increased carbon dioxide and other greenhouse...

Resistant HIV quickly hides in infants' cells

Mice with a migraine show signs of brain damage

...treat the pain. We’re going beyond that. Migraines could be dangerous. The focus should be on prevention,?said Nedergaard, who notes that by the time a person feels pain or notices a visual disturbance, the changes to the brain are already well underway. To make the finding, the team used a sophisticate...

Salk scientists hammer out a pathway that promotes muscle cell survival in mice

...ss known as phosphorylation, muscle-specific genes could not be activated and the mice lacked proper muscle function. In order to determine how CREB acts to regulate HDAC, Berdeaux and colleagues looked for phosphorylation sites in the HDAC protein. They discovered that one of many proteins turned on a...

The study was extended to soccer players heading the ball repeatedly from long and high goal kicks. No increased levels of biochemical markers for brain damage ...

'Personality-gene' makes songbirds curious

...erson - such individual differences in personality could be partly due to the genes you carry. In humans, it is hard to prove the existence of such "personality genes" - there are simply too many factors that influence human behaviour and these factors are hard to control experimentally. Birds are an easie...
