In the migratory marathon, parasitized monarchs drop out early

...migrations of any insect species. Emory University researchers found that monarchs infected with a protozoan parasite fly slower, tire out faster and expend more energy flying than healthy monarchs. These results, published in the March issue of Ecology Letters, could explain why parasite infections are much lo...

Scientists discover how fish evolved to float at different sea depths

...wimbladder system. Dr Berenbrink continued: "Many researchers believe that the swimbladder evolved from a primitive lung, which can be traced back 400 million years. These findings will help us to understand the diversity and success of modern fishes in their environment." Dr Berenbrink's research will be publ...

Gene therapy for Parkinson's disease moves forward in animals

...s." Meanwhile, in separate experiments with rats, researchers used gene therapy to completely reverse abnormal movements called dyskinesias in some of the animals, suggesting a new way to combat the flailing movements produced by a widely used drug treatment for Parkinson's disease. Levodopa, considered the gol...

Scientists find fossil proof of Egypt's ancient climate

... for greater mobility throughout the region." The researchers noted that the silt thickness at the lake exceeds five yards, an indication that the humid phase lasted at least several thousand years. Normal rainfall in the area they study is a minuscule 0.7 of a millimeter per year, but there is evidence that th...

VCU Researchers Identify Networks Of Genes Responding To Alcohol In The Brain

Virginia Commonwealth University researchers have identified several genetic changes in the brains of mice caused by ethanol, which may help researchers better understand how and why people become addicted to alcohol. In the March issue of the Journal ...

Opposing fat metabolism pathways triggered by a single gene

...tode. Using RNAi to suppress gene expression, the researchers discovered that when nhr-49 was absent, the lifespan of the nematode was reduced by more than 50%, and the animal displayed numerous gross abnormalities in the gut and gonad. This was accompanied by unusually high fat content in the larvae. They furt...
