Lack of enzyme turns fat cells into fat burners

... can eat a high fat, highcarbohydrate diet without gaining weight, while their normalcounterparts become obese and develop type 2 diabetes."This adds another tissue or organ that helps out in the process ofenergy maintenance," said Wakil. "ACC2 is potentially a key enzyme inthe regulation of weight, obesity,...

Sexual cooperation: Mating increases longevity in ant queens

...ocondyla obscurior actually benefit from mating by gaining increased lifespan and reproductive success, living longer irrespective of whether males could transfer viable sperm or had been sterilized prior to mating. It remains unknown how mating increases the longevity of the females. Sexual cooperation, ra...

NIAID begins clinical trial of West Nile virus vaccine

...the production of antibodies to block the WNV from gaining entry into cells, and killer T cells, which kill WNV-infected cells outright. "The DNA vaccine's exploitation of both cellular and antibody immunity offers a potentially potent defense against West Nile virus," says Barney Graham, M.D., Ph.D., chief...

UCSD research reveals mechanism involved with type of fatal epilepsy

... experiments to test these models with the hope of gaining the necessary insights to develop potential therapies for Lafora disease. Co-authors are Matthew S. Gentry, Ph.D., and Carolyn A. Worby, Ph.D., both of the UCSD Department of Pharmacy. This research was funded by the National Institutes of Health. ...

Prescription Drug Patches Gaining Ground, Tackling New Therapies

...portant healthcare product category. While quietly gaining market share for the treatment of chronic conditions such as angina, hypertension and HRT, the technology is set to make further inroads as transdermal patches for a host of new conditions wind their way through the development and clinical trial pro...

NHGRI targets 12 more organisms for genome sequencing

...sms." Two of the sequencing projects are aimed at gaining new insights into model organisms utilized in research on drug development and disease susceptibility. They are: sequencing the genome of a fellow primate, the marmoset (Callithrix jacchus); and identification of genetic variations (in the form of si...

Genome study of beneficial microbe may help boost plant health

...ens is called "biological control." That method is gaining momentum as a way to grow healthy plants without using synthetic fungicides. In all, about three dozen beneficial microbes are currently used as an environmentally-friendly way to fight plant diseases. Joyce E. Loper, senior author of the genome pap...

Recombinant DNA technology may enable oral, rather than injectable, delivery of protein drugs

...h can prevent them from crossing the intestine and gaining access to the sites where they are needed. They are also very sensitive to digestive enzymes and may be destroyed by stomach acid before they can be absorbed." To sidestep the difficulty of getting these large protein drugs through the GI tract intac...

When it comes to cell entry, being average has its advantages

When it comes to gaining entry into cells, size matters. A team from Brown University and the Max Planck Institute for Metals Research has created a model that explains how viruses and other bioparticles slip inside cells without a special protein coating called clathrin. T...

Biologists determine genetic blueprint of social amoeba

...for a host of genes that cause human disease, thus gaining a new and efficient way to study those human diseases with a simple organism in their laboratories. For evolutionary biologists, the genetic blueprint of Dictyostelium, the first amoeba genome to be sequenced, has clarified the place that Dictyostel...

Bees, Brains and Addiction

...rs last week that neurobiologists like himself are gaining a better understanding of human addiction by examining simpler brains, such as those of bees. Bees learn to land on a tile of a certain color after they are rewarded just once with sugar water for landing on that color. A single nerve cell in a bee'...

...elephants and lions ( Panthera leo ). "Obviously, gaining public acceptance is going to be a huge issue, especially when you talk about reintroducing predators," said the paper's lead author, Josh Donlan, a graduate student in Cornell's Department of Ecology and Evolutionary Biology, pointing to the controv...

Ants, not evil spirits, create devil's gardens in the Amazon rainforest, study finds

...he growth and establishment of D. hirsuta, thereby gaining more nest sites." The plants also benefit by increasing their biomass and eliminating the competition, says co-author Michael J. Greene, a former Sanford postdoctoral fellow, now assistant professor of biology at the University of Colorado-Denver. "...

Weight control protein may yield antiobesity drugs

...ice. After 5 weeks of age, however, the mice began gaining weight rapidly and were about twice as heavy as normal littermates after several months, with at least a 2.8-fold increase in body fat content. The mice also exhibited a near doubling of blood lipid levels and their livers grew to more than twice th...

Double trouble: Cells with duplicate genomes can trigger tumors

...c instability sets in, tumors "evolve " by losing, gaining and rearranging chromosomes. Late-stage tumors commonly have too many centrosomes and a near triploid chromosome number (one and a half times the normal chromosome content). Because the cells with extra chromosomes and centrosomes are biologically ...

New possibilities for flu antiviral and vaccine research emerge from 'Spanish flu' virus

...is research and concluded that the knowledge we're gaining to potentially protect public health far outweighs the risk of working with this virus," said Donald Kennedy, editor-in-chief of Science. "We were comforted to learn that this also was the conclusion of Dr. Anthony Fauci of the U.S. National Institu...

Low-cost drug gaining favor for use in HIV-infected children in poor countries

...AIDS, also said preventive use of cotrimoxazole is gaining wide acceptance. "It's a very cheap strategy," he said, "and the drug is very available, a lot more available in many areas where antiretroviral drugs are not around." Cotrimoxazole is not a substitute for antiretroviral treatment, but the antibio...

High-tech tags on marine animals yield valuable data for biologists and oceanographers
