NIH gives $8M to University of Pittsburgh School of Medicine for myositis research

...means that the bodys immune system, which normally fights infections and viruses, for reasons unknown turns on itself and attacks the muscle tissue and sometimes skin, joints and lungs, causing rash, arthritis and shortness of breath. The University of Pittsburgh-led study will evaluate the effectiveness...

How fish punish 'queue jumpers'

...ting discovery is that, in order to avoid constant fights and keep the social order stable, the fish seem to accept the threat of punishment and adjust their own size in order to avoid presenting a challenge to the one above them, she says. Social hierarchies are very stable in these fish and in practice...

Revealed -- Mosquito genes that could be controlling the spread of killer viruses

...annot have evolved an effective immune system that fights off the pathogen, we may be able to use this knowledge to enhance specific reactions of the immune systems in other mosquitoes to control the spread of the disease....

Pendulum love, science class gender gaps, musical mind mirrors, and unparticle physics

...What's nerdier than creating an online avatar that fights dragons and raids strongholds? Creating a virtual pendulum that you can sync up to your real-life pendulum. Leave it to physicists to do just that, resulting in a mixed reality state in which the two pendulums swing as one. Vadas Gintautas and A...

Mucosal-surface immune function discoveries could boost vaccine research

...ginning. "A better understanding of how the body fights off mucosal pathogens helps us immensely when we try and develop vaccines that target these areas," he explains. "By taking advantages of these mechanisms, we should move that much closer to interventions that shield millions against potentially leth...

Fat screen delivers plant-derived chemical with antidiabetic effects

...discovered that an ingredient found in some plants fights diabetes in mice without some of the side effects attributed to other antidiabetes drugs. The chemical they pinpointed, known as harmine, was first isolated more than 150 years ago from plants traditionally included in ritual and medicinal preparatio...

Fighting for their attention

...hoice. Male coalition formation is observed during fights in this population. Usually coalition formation will be driven by short-term gains for the helper (for example access to females). But there do not appear to be any short-term benefits in coalition and alliance formation in this population. Instead o...

Fish can determine their social rank by observation alone, study finds

Why do males and females of some species look so different?

...elopment of male-specific horns (which are used in fights over females), Moczek discovered that growth of horns is surprisingly uniform across sexes. Instead, both sexes undergo a second developmental period during which the female beetles reabsorb massive amounts of horn tissue that they had grown just a f...

Fighting like a girl or boy determined by gene in fruit flies

Natural anti-viral enzyme helps keep cancer cells alive, researchers find

...ly understood about how the adaptive immune system fights cancer and also helps create tissue environments permissive to cancer, Dr. White said, but a cancer-promoting role for the host defense response has not been previously seen. It's a straightforward matter to block the action of TBK-1, so this might b...

Other highlights in the June 21 JNCI

...d, a non-steroidal anti-inflammatory drug (NSAID), fights pancreatic cancer by reducing the levels of some cellular proteins that contribute to tumor growth and metastasis. Stephen Safe, Ph.D., of Texas A&M University in College Station, and colleagues at the M.D. Anderson Cancer Center in Houston, Tx., use...

LIAI finding gives boost to bioinformatics use in fighting disease

...mune responses, which are essentially how the body fights a disease-causing agent, are a crucial element of vaccine development. "We are excited because this further validates the important role that bioinformatics can play in the development of diagnostic tools and ultimately vaccines," said Alessandro ...

National Institutes of Health funds $13.7 million for Texas tuberculosis study

...t might be good sites for a drug to latch on as it fights the disease. These drug targets can reduce the time required for therapy because the medicine would be a straight shot, so to speak, at the pathogen. "Most people who start therapy never finish. In some of the most infected countries in the world, it...

Developing nations may save the tropical forest

...o far, even the Bush Administration, which usually fights initiatives to establish binding national commitments to reduce greenhouse-gas emissions, has remained silent," said Laurance. Nevertheless, no one imagines that implementing the proposal will be easy. "There are still many hurdles to clear," sai...

Animals can change genes quickly to keep up with viral ingenuity

...genes controlling a part of the immune system that fights viruses actually evolve much faster than almost all other genes, evidence of the host's evolutionary race to keep the viruses at bay. In their research, the scientists found evidence that some genes that participate in so-called RNAi mechanisms evolv...

Biggest physics meeting of the year

...with or against the force of gravity. Gravikinesis fights the paramecium's natural tendency to settle to the bottom of a body of water and form sediment; as a result it swims harder upward than downward. Karine Guevorkian ( guevorkian@physics.brown.edu ) and James M Valles Jr. of Brown University have succe...

U-M scientists identify major psoriasis susceptibility gene

... complex (MHC) that regulate how the immune system fights off infection. MHC genes carry DNA-coded instructions for proteins whose job it is to distinguish between what belongs in the body and what doesn't. "There is a great deal of genetic variation in the MHC, because it's on the front lines of dealing wi...

Male loons change their tune with change in territory

...s and fight for the territory and the females. The fights can be to the death, with males diving and rising up under a foe in an effort to spear a rival through the chest and heart with his long, pointed beak. It turns out that the victor gets more than the female -- he gets a new voice: He changes his voc...
