Animals can change genes quickly to keep up with viral ingenuity
Viruses are famous for evolving quickly, but the organisms they infect can't be expected to sit idly by. view more (2006-03-21)
Velociraptor had feathers
A new look at some old bones have shown that velociraptor, the dinosaur made famous in the movie Jurassic Park, had feathers. A paper describing the discovery, made by paleontologists at the American Museum of Natural History and the Field Museum of Natural History, appears in the Sept. 21 issue of the journal Science. view more (2007-09-21)
Solar-Powered Sea Slugs Live Like Plants
The lowly sea slug, "Elysia chlorotica," may not seem like the most exciting of creatures, but don't be fooled: it behaves like a plant and is solar-powered, says a Texas A&M University biologist who has been studying these tiny creatures for the past decade and, along with collaborators from several universities, has identified a... view more...

Ethics of research involving animals
The Nuffield Council on Bioethics today announced a new Working Party to consider the ethics of research involving animals. There is considerable discomfort about the use of animals in research, but also a widespread acceptance of the need to do more medical research, which currently involves the use of animals. "We believe there is a need... view more... (2003-03-17)
Antarctic krill provide carbon sink in Southern Ocean
New research on Antarctic krill (Euphausia superba), a shrimp-like animal at the heart of the Southern Ocean food chain, reveals behaviour that shows that they absorb and transfer more carbon from the Earth's surface than was previously understood. view more (2006-02-07)
Scientist's persistence sheds light on marine science riddle
When he started compiling an online database of seashells 15 years ago, Dr. Gary Rosenberg did not envision that his meticulous record-keeping would eventually shed light on a 40-year-old evolutionary debate. view more (2006-09-08)
Report lists top 20 most-vulnerable African carnivores
It may still be "king of the beasts," but the African lion's kingdom is dwindling, according to a new report released by the New York-based Wildlife Conservation Society (WCS) that says these emblematic big cats have disappeared from 82 percent of their historic distribution over the past several decades. view more (2006-02-02)
Scientists develop first comprehensive theory explaining Madagascar's rich biodiversity
An international team of scientists has developed an explanation for why Madagascar has such a wealth of animals found only on this island. view more (2006-05-19)
Why Sloths Do Not Sleep Upside Down
Several mammal species other than ruminants and camels have a multi-chambered forestomach - kangaroos, hippos, colobus monkeys, peccaries, sloths - but they do not ruminate. As studies on the digestive physiology of these species are largely missing, it is generally assumed that their forestomach functions in the same way as that of ruminants,... view more...

480-million-year-old fossil sheds light on 150-year-old paleontological mystery
Discovery of an exceptional fossil specimen in southeastern Morocco that preserves evidence of the animal's soft tissues has solved a paleontological puzzle about the origins of an extinct group of bizarre slug-like animals with rows of mineralized armor plates on their backs, according to a paper in Nature. view more (2008-01-10)
Richness of Marine Life is Under Threat
Future potential for the production of new wonder drugs - including anti-cancer agents - from marine animals and plants, is under threat according to biodiversity expert Professor Carlo Heip, speaking at the European marine science and ocean technology conference EurOCEAN 2004 in Galway, today. According to Professor Heip, marine biodiversity -... view more... (2004-05-11)
Don't move a muscle: Evolutionary insight into myogenesis
In a paper released online ahead of its scheduled December 15th publication date, Dr. Michael Krause (NIH) and colleagues detail the transcription network that drives muscle development in the roundworm C. elegans, and make a strong argument for an evolutionarily conserved program of myogenesis in all animals. view more (2006-12-07)
Origins of nervous system found in genes of sea sponge
Scientists at the University of California, Santa Barbara have discovered significant clues to the evolutionary origins of the nervous system by studying the genome of a sea sponge, a member of a group considered to be among the most ancient of all animals. view more (2007-06-06)
Insight into dopamine role suggests new treatment pathway for Parkinson's
Dopamine (DA) not only functions as a neurotransmitter, a chemical messenger between neurons by which one neuron triggers another, researchers have found. view more (2006-10-19)
Reconstructed 1918 influenza virus induces immune response that fails to protect
An analysis of mice infected with the reconstructed 1918 influenza virus has revealed that although the infection triggered a very strong immune system response, the response failed to protect the animals from severe lung disease and death. view more (2006-09-28)
Weight control protein may yield antiobesity drugs
A weight control protein with a key role in the brain's ability to monitor body fat content may yield new approaches for treating obesity and type 2 diabetes, according to a new report in the August issue of Cell Metabolism. view more (2005-08-17)
Scientists develope a new model of artificial canine skin
Researchers at UNIVET, a spin-off of the Universitat Autònoma de Barcelona, in cooperation with the animal nutrition company Affinity Petcare, have developed an artificial cellular model which faithfully reproduces the characteristics of dog's skin and which will allow, therefore, the carrying out of various lines of research related to... view more...

Media invitation - Environmental change in Antarctic lakes and seas: the chances for survival or extinction? BA Festival of Science, Univ of Leicester
The effects of the warming of the Earth`s climate on Antarctic lakes and seas is a matter of life or death for many plants and animals at the frozen continent. Professor Lloyd Peck, biologist with British Antarctic Survey (BAS) discusses the prospects for survival or extinction of Antarctic marine and lake life today (9 Sept) at a special seminar... view more...

Scientists discover a genetic switch that links animal growth and cancer
Laboratory discoveries by scientists at two universities may lead to new directions in cancer therapy drugs. view more (2006-04-18)
Master genetic switch found for chronic pain
In experiments with mice, researchers have found that eliminating what appears to be a master genetic switch for the development of pain-sensing neurons knocks out the animals' response to "neuropathic pain." view more (2006-01-26)
