Virtual Reconstruction Of A Neanderthal Woman’s Birth Canal Reveals Insights Into Evolution Of Human Child Birth:

Researchers from the University of California at Davis (USA) and the Max Planck Institute for Evolutionary Anthropology in Leipzig (Germany) present a virtual reconstruction of a female Neanderthal pelvis from Tabun (Israel).

Why Coral Reefs Around The World Are Collapsing:

An explosion of knowledge has been made in the last few years about the basic biology of corals, researchers say in a new report, helping to explain why coral reefs around the world are collapsing and what it will take for them to survive a gauntlet of climate change and ocean acidification.

Americans Choose Media Messages That Agree With Their Views:

A new study provides some of the strongest evidence to date that Americans prefer to read political articles that agree with the opinions they already hold. Researchers found that people spent 36 percent more time reading articles that agreed with their point of view than they did reading text that challenged their opinions.

New Malaria Agent Found In Chimpanzees Close To That Commonly Observed In Humans:

Researchers based in Gabon and France report the discovery of a new malaria agent infecting chimpanzees in Central Africa. This new species, named Plasmodium gaboni, is a close relative of the most virulent human agent P. falciparum.

Lessons From The Past: Research Examines How Past Communities Coped With Climate Change:

Research led by the University of Leicester suggests people today and in future generations should look to the past in order to mitigate the worst effects of climate change.

Spring Agricultural Fires Have Large Impact On Melting Arctic:

Scientists from around the world will convene at the University of New Hampshire June 2-5, 2009, to discuss key findings from the most ambitious effort ever undertaken to measure “short-lived” airborne pollutants in the Arctic and determine how they contribute in the near term to the dramatic changes underway in the vast, climate-sensitive region.

Fallow Deer Become Hoarse In The Hunt For A Mate:

Fallow deer become hoarse when trying to attract a mate, according to scientists from Queen Mary, University of London. Writing in the journal Animal Behaviour, Dr Alan McElligott from Queen Mary’s School of Biological and Chemical Sciences has found that male fallow deer (bucks) can call for a mate more than 3000 times per hour during the peak of the mating season. Their prolonged vocal efforts cause their call structure to break down, leaving them hoarse.

Neurological Disorder In Golden Retriever Dogs Caused By A Mutation In Mitochondrial DNA:

Sensory ataxic neuropathy (SAN) is a recently identified neurological disorder in Golden Retriever dogs with onset during puppyhood. Affected dogs move in an uncoordinated manner and have sensory deficits. Researchers from the Swedish University of Agricultural Sciences, Uppsala University and the Karolinska Institutet have now revealed that SAN is caused by a mutation in mitochondrial DNA.

Blue Whale Discovered Singing In New York Coastal Waters:

For the very first time in New York coastal waters, the voices of singing blue whales have been positively identified. Acoustic experts at the Cornell Lab of Ornithology’s Bioacoustics Research Program (BRP) and the New York State Department of Environmental Conservation (DEC) confirmed that the voice of a singing blue whale was tracked about 70 miles off of Long Island and New York City on Jan. 10-11, 2009, as the whale swam slowly from east to west. At the same time, a second blue whale was heard singing offshore in the far distance.
