Bird Brains Show How Trial and Error May Contribute to Learning
The adult male zebra finch knows only one scratchy tune learned in its youth, which it performs repeatedly and intensely when females are listening. But occasionally, the finch might improvise, experimenting with a slower, more sultry variation or emphasizing different notes. Neurobiologists studying the finch now say the improvisation arises from a component of a crucial learning circuit...Fibril Shape Is The Basis Of Prion Strains And Cross-species Prion Infection
New research on prions, the infectious proteins behind "mad cow" disease and Creutzfeld-Jakob disease in humans, suggests that the ability of prions in one species to infect other species depends on the shape of the toxic threadlike fibers produced by the prion. Two studies on the topic appear in the 8 April issue of the journal Cell. Although research suggests that prions from one specie...Birds brains reveal source of songs
Scientists have yearned to understand how the chirps and warbles of a young bird morph into the recognizable and very distinct melodies of its parents. Neuroscientists at the McGovern Institute for Brain Research at MIT now have come one step closer to understanding that process. They've shown for the first time how a particular brain region in birds serves as the source of vocal creativity....Supercomputers to focus brains on AIDS dilemma
More than two decades after it burst onto the scene, HIV/AIDS has claimed more than twenty million lives and continues to devastate societies around the world, particularly in Africa and other developing countries. In the late 1980s and early 1990s, after years of effort AIDS researchers succeeded in developing a class of drugs that proved to be highly effective against AIDS. By blocking the acti...Mice brains shrink during winter, impairing some learning and memory
The brains of one species of mouse actually shrink during the winter, causing the mice to have more difficulty with some types of learning, a new study found. This is one of the first studies to show...Yeast Deletion Parental Strains S. cerevisiae Hansen BY4741 from Invitrogen

Genetic variations in the HIV strains in Africa make it more difficult for the anti AIDS drugs to act on them according to researchers. This however does not mean that these drugs will be powerless against the virus but these drugs find it difficult to latch on to the protease, which is an enzyme useful in the replication of the virus inside the body. If the drug attaches itself to the p...E. coli strains resistant to a common antibiotic
Food contaminated with a strain of drug-resistant E. coli has emerged as a possible new source of urinary tract infections. E. coli is a normal inhabitant of the digestive tract that can cause both intestinal upsets and urinary infections. But while E. coli from bad food is a frequent cause of diarrhoea and other digestive miseries, urinary tract infections were thought until now to resul...Pulses and grains protect the heart
Eat fruits and vegetables, but don't forget whole grains, if you want to cut your risk for heart and blood vessel disease and cancer, researchers say.// Fruits and vegetables especially cruciferous vegetables like broccoli, cauliflower and cabbage - can reduce stroke risk by about 32%. According to a study of a group of 65,000 women, those who ate the equivalent of two to three s...Hormone restrains appetite in man
According to reasearchers, a hormone is released into the blood after a meal, restrain the appetite if given by injection and might be supportive in treating obesity. The reason for feeling full after a meal, that the intestines release a hormone called PYY3-36 //which acts on the brain to produce a feeling of satiety.
