Rare insect fossil reveals 100 million years of evolutionary stasis Thursday, February 3, 2011 - 00:00
Researchers have discovered the 100 million-year-old ancestor of a group of large, carnivorous, cricket-like insects that still live today in southern Asia, northern Indochina and Africa. The new fin
How insects survive the long, cold winter Thursday, February 3, 2011 - 00:00
In many species, insects adapt to the cold by dying off; it's the larval stage of the species that goes through winter. Insects that do over-winter as adults usually enter a hibernation-like state cal
Study doubles number of known human structural variants Thursday, February 3, 2011 - 00:00
1000 Genome Project data helps researchers understand the role of structural variation in human health and disease
Wolverine population threatened by climate change Thursday, February 3, 2011 - 00:00
The aggressive wolverine may not be powerful enough to survive climate change in the contiguous United States, new research concludes.
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,
