Rats May Be Pessimistic Too
Rats housed in unpredictable conditions appear to have a more negative outlook than those housed in stable, settled conditions, according to new research by scientists at Bristol University Veterinary School, published in this week's issue of Nature. The researchers found that whether an animal anticipates that something good or bad is going to... view more... (2004-01-19)
How Toxoplasma gondii gets noticed
Researchers provide insight into how Toxoplasma gondii, a common parasite of people and other animals, triggers an immune response in its host. view more (2009-01-20)
Fossil steroids record the advent of earliest known animals
Using compounds preserved in sedimentary rocks more than 635 million years old, researchers have found some of the earliest evidence for the existence of animals. view more (2009-02-05)
Jefferson scientists find rabies-based vaccine could be effective against HIV
Rabies, a relentless, ancient scourge, may hold a key to defeating another implacable foe: HIV. Scientists at Jefferson Medical College in Philadelphia have used a drastically weakened rabies virus to ferry HIV-related proteins into animals, in essence, vaccinating them against an AIDS-like disease. view more (2007-04-04)
Mammals that hibernate or burrow less likely to go extinct
The best way to survive the ill-effects of climate change and pollution may be to simply sleep through it. view more (2009-01-29)
Diversity in the deep blue seas
Nature magazine has published an article by Xabier Irigoien, a researcher at AZTI, the Basque Fisheries and Marine Technological Research Centre. The article provides data on the diversity of marine life at the bottom of the sea - particularly amongst algae. Species diversity Most research carried out on the diversity of species has been with land... view more... (2004-06-28)
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)
The clustering of Hox genes, involved in the determination of body segments, is not necessary for their proper function
The Hox genes (also known as homeotic genes) play a crucial role in the development of animals, being involved in the determination of segment identity along the body axis. These genes were discovered in the fruit fly Drosophila melanogaster 90 years ago and have been found later in all animals, including humans. The Hox genes are arranged in the... view more...

Humans are reason for why domestic animals have strange and varied coat colors
HUMANS have actively changed the coats of domestic animals by cherry-picking rare genetic mutations, causing variations such as different colours, bands and spots, according to a new study. view more (2009-01-16)
Horse whisperers, lion tamers not needed: Scientists find genetic regions that soothe savage beasts
In what could be a breakthrough in animal breeding, a team of scientists from Germany, Russia and Sweden have discovered a set of genetic regions responsible for animal tameness. view more (2009-06-09)
'Beating' heart machine expedites research and development of new surgical tools, techniques
A new machine developed at North Carolina State University makes an animal heart pump much like a live heart after it has been removed from the animal's body, allowing researchers to expedite the development of new tools and techniques for heart surgery. view more (2009-05-12)
Ancient oceans offer new insight into the origins of animal life
Analysis of a rock type found only in the world's oldest oceans has shed new light on how large animals first got a foothold on the Earth. view more (2009-09-10)
Ducks go quackers for dishy drakes
Good-looking males produce healthiest families Every parent wants to ensure their offspring get the best start in life, but it seems that offspring of attractive parents might be getting a better start than others. Studies of mallard ducks carried out by scientists based at the University of Cambridge show that females are laying bigger eggs for... view more... (2000-02-29)
Detecting transmissibility of avian influenza virus in human households
Recent outbreaks of emerging diseases such as SARS and H5N1 avian influenza have underlined the fact that animal pathogens may acquire the ability to spread efficiently in humans - but as yet have not. view more (2007-07-26)
Antarctic animals are under threat from illegal fishing
Animals in the oceans surrounding Antarctica are under increasing threat. Fishery management organisations and governments need to do more to eliminate illegal fishing and regulate better legal fishing in Southern Ocean and adjacent areas according to Professor John Croxall speaking today (17 Feb) at a special symposium - Conserving Migratory... view more...

Tree lizard's quick release escape system makes jumpers turn somersaults
If you've ever tried capturing a lizard, you'll know how difficult it is. But if you do manage to corner one, many have the ultimate emergency quick release system for escape. view more (2009-02-13)
Aging impairs the 'replay' of memories during sleep
Aging impairs the consolidation of memories during sleep, a process important in converting new memories into long-term ones. view more (2008-07-30)
Finding an answer to Darwin's Dilemma
The sudden appearance of large animal fossils more than 500 million years ago - a problem that perplexed even Charles Darwin and is commonly known as "Darwin's Dilemma" - may be due to a huge increase of oxygen in the world's oceans, says Queen's paleontologist Guy Narbonne, an expert in the early evolution of animals and their... view more...

Prairie dogs: influencing the accumulation of metals in plants?
Prairie dogs may seem like harmless little creatures, but they can inflict serious injury on plants simply by snacking on them. Plants cannot flee from their furry predators, so how do they avoid becoming a prairie dog's lunch? view more (2009-06-24)
Estimating the risk of cancer
Dutch scientists have developed a new tumour growth model in which the tumour is a part of the host's body. The model reveals that a low-calorie diet delays the growth of a tumour, and thus increases the life expectancy. Furthermore, tumours were found to develop faster in younger than in older hosts. Ingeborg van Leeuwen has developed a new... view more... (2003-12-19)
