Molecular fossils uncover link between viruses and the immune system
Researchers from the Viikki Biocenter, University of Helsinki, show that atomic structures can reveal evolutionary history of viruses in a similar fashion as fossils did for the dinosaurs and reptiles. Their article is published in the April 15 issue of Molecular Cell. view more (2005-04-14)
Fossilised Embryos - 500 Million Years Old
Evidence from fossilised embryos of worm-like creatures that lived 500 million years ago shows that embryos developed then in much the same way as their living relatives do today. The implications of this remarkable discovery, reported in this week's issue of Nature, is that embryological processes that occur today must have been established very... view more... (2004-01-12)
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)
Tulane researcher reports on origin of deadly fever outbreak
Bats or other cave dwelling animals may have been responsible for the deadly 1998-2000 outbreak of Marburg hemorrhagic fever among gold miners in the Democratic Republic of the Congo. view more (2006-09-14)
Researchers Studying Hearing Loss in Adult Animals Find that Auditory Regions of the Brain Convert to the Sense of Touch
Virginia Commonwealth University School of Medicine researchers have discovered that adult animals with hearing loss actually re-route the sense of touch into the hearing parts of the brain. view more (2009-03-25)
Cefic bestows first Innovative Science Award
Cefic, the European Chemical Industry Council, announces the winner of the first LRI (Long-range Research Initiative) Innovative Science Award. Dr. Roger Godschalk of University of Maastricht, The Netherlands will receive EUR100,000 to conduct research on Paternal carcinogen exposures and genetic risks in their offspring. The award was presented... view more... (2004-06-16)
Bigger is smarter
When it comes to estimating the intelligence of various animal species, it may be as simple measuring overall brain size. In fact, making corrections for a species' body size may be a mistake. view more (2007-05-21)
Mice offer clues to the roots of human resilience
When faced with adversity, some people succumb to debilitating psychological diseases including posttraumatic stress disorder and depression, while others are able to remain remarkably optimistic. view more (2007-10-19)
Spinal cord injury research hampered by animal models, says new study
Research on traumatic spinal cord injuries is hampered by a reliance on animal experiments that don't accurately predict human outcomes, says a new study in the upcoming edition of the peer-reviewed journal Reviews in the Neurosciences. The review was written by scientists with the Physicians Committee for Responsible Medicine. view more (2008-04-29)
Stress could damage DNA
A ground-breaking experiment has suggested that a certain type of stress could actually damage humans' DNA. view more (2004-08-23)
Stress causes parodontis
Under stress, major proteins get actively destroyed in the parodentium. According to biologists' data, chronical stress inhibits the osseous tissue maturing process and intensifies decomposition of collagen protein and proteoglycans with the animals non-resistant to stress. Stress intensifies hydrolysis of proteins, which make the basis of the... view more... (2003-09-26)
Jefferson Researchers Find Drug May Give Some Cardiac Protection 24 Hours After Heart Attack
A drug has been shown to provide some protection to the heart from injury even if given as much as 24 hours after a heart attack view more (2005-11-17)
Natural, soy-based substance might help fight MS, Jefferson neuroscientists find
A natural substance made from soy appears to have amazing restorative powers when given to animals with a multiple sclerosis (MS)-like disease. view more (2006-12-13)
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)
Emerging (disease) markets
Instead of attacking wild birds for our new disease problems, a far more cost effective approach should focus on keeping wild animals separate in the places where they often commingle: in wildlife markets and international trade. view more (2007-08-16)
Extract of broccoli sprouts may protect against bladder cancer
A concentrated extract of freeze dried broccoli sprouts cut development of bladder tumors in an animal model by more than half, according to a report in the March 1 issue of Cancer Research, a journal of the American Association for Cancer Research. view more (2008-02-28)
UGA research shows rats are capable of reflecting on mental processes
Let's say a college student enters a classroom to take a test. She probably already has an idea how she will do—knowledge available before she actually takes out a pencil. But do animals possess the same ability to think about what they know or don't know? view more (2007-03-09)
MICROWAVE FOR ANIMALS' STERILIZATION
As soon as human beings domesticated the first wild animals, they faced the challenge of regulating the animals' reproductive function. Even nowadays the issue has not been solved yet. Traditional surgical sterilization techniques are uneconomical and the animals survive them uneasily even if the operation is performed under general anaesthetic.... view more... (2003-04-25)
Polar pecking order and biodiversity
New research into how biodiversity is generated and maintained in the seas surrounding hostile Polar Regions is reported in this month`s Proceedings of the Royal Society (Biological Sciences). British Antarctic Survey biologist David Barnes studied `battles` between rock-dwelling marine organisms in shallow seas from the Poles to tropics to come... view more... (2002-10-07)
Study shows marine omega-3 fatty acids have positive effect on muscle mass
A research team led by Carole Thivierge, from Université Laval's Institute of Nutraceutics and Functional Foods, shows that omega-3 fatty acids from fish oil have a positive effect on the metabolism of muscle proteins. view more (2007-05-10)
