Birds use right nostril to navigate: Pigeons are disoriented without olfactory sense Thursday, February 3, 2011 - 00:00
Pigeons rely mainly on their olfactory sense when they navigate. Young pigeons learn to recognize environmental odours carried by the winds into the loft and to use these odours to find their way home
Neutrons 'go viral' at ORNL: Neutron scattering study yields new insights into virus life cycle Thursday, February 3, 2011 - 00:00
Without a host, a virus is a dormant package of proteins, genetic material and occasional lipids. Once inside a living cell, however, a virus can latch onto cell parts and spring into action - mutatin
Biologists discover 'control centre' for sperm production Wednesday, February 2, 2011 - 00:00
Study uncovers genetic hierarchy in plant sperm formation. They have found that a gene in plants, called DUO1, acts as a master switch to ensure twin fertile sperm cells are made in each pollen grain
Lampreys give clues to evolution of immune system Wednesday, February 2, 2011 - 00:00
Biologists have discovered that primitive, predatory lampreys have structures within their gills that play the same role as the thymus, the organ where immune cells called T cells develop in mammals,
Extreme X-ray pulses create unique image of intact virus Wednesday, February 2, 2011 - 00:00
international research team has managed to capture an image of an intact virus and a membrane structure from a photosynthetic bacterium with the aid of extremely intensive and ultra-short x-ray pulses
DNA: Building block for smaller, smarter electronics? Wednesday, February 2, 2011 - 00:00
Using a concept called DNA origami, Arizona State University researchers are trying to pave the way to produce the next generations of electronics products.
Experiment reaches biology milestone with hard X-ray laser Wednesday, February 2, 2011 - 00:00
Arizona State University builds protein beam injector; contributes nanocrystals
Synthetic materials that behave like mollusk shells Wednesday, February 2, 2011 - 00:00
Nacre, commonly known as mother-of-pearl, is the iridescent material lining many mollusk shells. It is part of a two-layer armor system that protects the animal from predators. The brittle outer layer
