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)
Elephants avoid costly mountaineering
Using global-positioning system data corresponding to the movements of elephants across the African savannah, researchers have found that elephants exhibit strong tendencies to avoid significantly sloped terrain, and that such land features likely represent a key influence on elephant movements and land use. view more (2006-07-25)
At petting zoos, simple disease prevention guidelines frequently ignored
A new study shows that simple guidelines to protect petting zoo patrons from disease-causing germs found in the zoo are frequently not followed, thus allowing the risks of contracting serious intestinal illnesses to persist. view more (2007-06-12)
High cholesterol diets modify gene expression in atherosclerosis
Scientists from the department of Biochemistry and Molecular Biology 1 of the University of Granada (Universidad de Granada) have proven that a high cholesterol diet causes changes in gene expression of chicken aortic smooth muscle cells at the early stages of an experimental atherosclerosis. view more (2007-06-13)
First live rhinoceros birth from frozen-thawed semen
There may be less than 20,000 rhinoceros in the world, with one species perhaps already extinct and another with possibly only four animals remaining in the wild. view more (2008-11-13)
Limping rat provides sciatica insights
A newly developed animal model for the painful nerve condition known as sciatica should help researchers diagnose and treat it, according to Duke University bioengineers and surgeons. view more (2009-04-30)
Research Fortnight 1 May issue: stories on animal alternatives, HEFCE`s funding plans, EPSRC adventure, quality assurance for research and NERC eligibility
Peers condemn 'inertia' on animal alternatives The development of alternatives to research using animals is being impeded by "inertia" in the scientific community and across government, according to the House of Lords select committee on animals in scientific procedures. In a meeting a fortnight ago peers criticised the Department of Health and... view more... (2002-05-01)
Higher stress leads to longer life
Eating less may make you healthier: even more reason to start that diet tomorrow. Scientists at the Plymouth Marine Laboratory have found that eating less helps marine animals cope with pollution and other stressful situations, and may even let them live longer. Professor Michael Moore found that triggering a cellular process known as autophagy in... view more... (2004-03-26)
Incentives for carbon sequestration may not protect species
Paying rural landowners in Oregon's Willamette Basin to protect at-risk animals won't necessarily mean that their newly conserved trees and plants will absorb more carbon from the atmosphere and vice versa, a new study has found. view more (2008-07-08)
American carnivores evolved to avoid each other, new study suggests
How do the many carnivorous animals of the Americas avoid competing for the same lunch, or becoming each other's meal? view more (2009-03-10)
New technology reveals seal behavior
New technology has allowed an international team including UK scientists from University of St Andrews and British Antarctic Survey to witness for the first time the behaviour of the southern elephant seal (Mirounga leonina) and how it relates to its physical environment. view more (2007-08-08)
Did pterosaurs feed by skimming?
In order to envisage the behaviors and lifestyles of now extinct animals, palaeontology often relies on extrapolating from modern species. Scientists identify shared anatomical features and infer from these shared ways of life. view more (2007-07-24)
Intensive training post-spinal cord injury can stimulate repair in brain and spinal cord
Intensive rehabilitation training for patients with spinal cord injuries can stimulate new branches growing from severed nerve fibers, alongside compensatory changes in the brain, say Canadian researchers. Most importantly, it could lead to restoring hand function and the ability to walk. view more (2007-12-19)
ETH Researchers Decipher Learning Processes in Mice
Protein phosphatase 1 (PP1) belongs to a group of molecules that on the basis of earlier studies has been proposed to be a controlling factor for learning and memory. The ETH researchers produced genetically modified mice in which the activity of PP1 can be reduced at will. These animals were subjected to various learning and memory tests in one... view more...

Mice with defective memory may hold clues to schizophrenia
By deleting a single gene in a small portion of the brains of mice, researchers at UT Southwestern Medical Center found that the animals were affected in a way resembling schizophrenia in humans. view more (2006-01-18)
Cell death occurs in the same way in plants, animals and humans
Research has previously assumed that animals and plants developed different genetic programs for cell death. view more (2009-10-14)
Why are some groups of animals so diverse?
A new study of finger-sized Australian lizards sheds light on one of the most striking yet largely unexplained patterns in nature: why is it that some groups of animals have evolved into hundreds, even thousands of species, while other groups include only a few? view more (2007-09-20)
Old before their time? Aging in flies under natural vs. laboratory conditions
Evolutionary studies of aging typically utilize small, short-lived animals (insects, worms, mice) under benign conditions - constant temperature and humidity, no parasites, superabundant food - in the laboratory. Oddly enough, very little is known about aging in such animals in their harsh, stressful natural environments. Could it be that these... view more... (2008-09-08)
Mice use specialized neurons to detect carbon dioxide in the air
For mice, carbon dioxide often means danger - too many animals breathing in too small a space or a hungry predator exhaling nearby. view more (2007-08-17)
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)
