...an extensive academic editorial board, and cover a broad range of research topics, from basic molecular science to clinical studies. Specific subjects include the evolution of language1, the control of rabies2, mimicry of jumping spiders3, and Alzheimer's disease4. And because the articles are published un...

Researchers map spread of pathogens in the human body

...and threats for the food industry. The work is of broad significance as these novel research approaches are applicable to a multitude of pathogenic microorganisms. These studies indicate that individual bacteria and their progenies cleverly escape from host cells and distribute to new sites of the body...

Stormy days ahead for coral reefs

...ulnerable corals are the table corals which have a broad flat top supported by a narrow stalk, making them more susceptible to strong wave forces than bushy or mounded corals. Vulnerability also depends on whether the coral grows on the front, crest, flat or the back of the reef, where the force of the wav...

Minorities, uninsured less likely to receive care at high-volume hospitals

... varies by race/ethnicity or insurance status in a broad population of patients undergoing complex surgical care. The researchers examined patient characteristics and use of high-volume hospitals across 10 hospital-based procedures with known volume-outcome relationships among Californians during a 5-year...

Bacterial protein shows promise in treating intestinal parasites

...ystal proteins will likely have activity against a broad range of nematodes, and could be used to treat children who are often infected with multiple intestinal parasites. Studies are underway to fully define the spectrum of activity of Cry5B as part of its preclinical development as a human therapeutic."...

...red in the spermatheca. The HBGSP has united a broad range of scientists, from leaders in human genomics and bioinformatics to members of diverse disciplinary and organism-based communities, including those studying mammals and humans. A total of 112 individuals in 63 institutions around the world sign...

UGA scientists engineer root-knot nematode resistance

...not nematodes provides a way to develop crops with broad resistance to this destructive pathogen," Hussey said. "Equally important, our approach makes available a strategy for developing root-knot-nematode-resistant crops for which natural resistance genes do not exist." ...

Tests for 'face-blindness' reveal disorder may not be so rare

...gait, clothing, voice, and context. There are two broad categories of prosopagnosia. Most documented cases have been of acquired prosopagnosia, due to brain damage suffered after maturity from head trauma, stroke, and degenerative diseases. The other type is called developmental prosopagnosia. These indiv...

Finding the right mix: A biomaterial blend library

...ers derived from the amino acid tyrosine make up a broad class of degradable biomaterials under investigation. Such materials provide a temporary scaffold for cells to grow and tissue to regenerate. In a 2006 study* presented at the national meeting of the American Chemical Society in September, the resear...

... of each mechanism." The new insights gained have broad implications. The principles discovered might govern also the control of other temporally regulated systems like embryonic development. The fast evolution of temporal regulation also raises the question in how far general conclusions about regulatory...

Eat less, weigh more? Enzyme makes lean mice 'susceptible' to dietary fat

... the bloodstream." Hopeful that the discovery has broad implications for understanding the genetic underpinnings of obesity and weight management, the Hopkins investigators say the work affirms the central role of the brain in managing hunger and satiety and offers up new targets for drugs that manipulate...

St. Jude test of bird flu vaccine proves successful

... vaccine could trigger an immune defense against a broad range of variants of the virus. "Even if the bird flu virus mutates so it becomes adapted to humans, this kind of cross protection will allow the immune system to track and attack such an emerging new variant without missing a beat," Webby said. "We...

Leptin has powerful effect on reward center in the brain

...on in the VTA is likely to have consequences for a broad range of behaviors and associated pathologies," DiLeone said. "These include obesity, drug addiction, and other impulsive behavior." Leptin's effect in the hypothalamus has been well studied, but it was not known how the hormone affected activity i...

Mutant mice show key autism traits

... The gene, called Pten, had been associated with a broad array of such disorders when knocked out throughout the animals' bodies. However, Parada and colleagues engineered mice to knock out the gene only in mature, or "postmitotic," neurons of the cerebral cortex and hippocampus in the brain. These regions...

So says the first broad field study of this charismatic orange creature's behavior in the wild, which was just published in the April 2006 issue of The Biological Bulletin. The new research is significant because the sea slug known as Tritonia diomedea, a nudibranch mollu...
