Newly discovered antibody may be body's natural defense against Alzheimer's

...rmal individuals. The basis for the selective recognition of oligomers by these antibodies appears to be their capacity to recognize the oligomer's misfolded shape. "That was a surprise, because most antibodies work by recognizing some aspect of the chemical structure of their target -- not their shape,...

Gene malfunctions cause schizophrenia, depression symptoms in mice

..."our findings lend further credence to the growing recognition that schizophrenia and bipolar disorder share, at least in part, common genetic etiologies and thus underlying molecular mechanisms." ...

Scientists identify prion's infectious secret

MIT's ocean model captures diversity of underwater forests

... advances in computational capability and a simple recognition of his own bias. "Physicists, like myself, have a bit of a reductionist view. We often shy away from the complexity of the real world in our models and prefer to reduce things to the simplest case with fewest factors," said Follows, who went throu...

The research, conducted by Cornell professor Doug Antczak, V.M.D, Ph.D., and funded by the National Institute of Child Health and Human Development, has implications in reproduction,...

A new study of living cells could revolutionize the way we test drugs

..., be detected with sensitive enough equipment. The recognition of such electrical activity would provide a kind of ‘cellular cardiogram? allowing the daily functioning of the cell to be monitored in a similar way to a cardiograph showing the workings of a human heart. With funding from the Engineering and Phy...

Study shows hope for early diagnosis of Alzheimer's

...ata using sophisticated signal processing, pattern recognition and artificial intelligence techniques to explore the hypothesis that the entire ERP signal, not just the P300 indicator, reveals markers that previously have not been associated with Alzheimer’s disease. The teams conducted several experiments, u...

Iowa State University botanists identify new species of North American bamboo

...nd other information to make a strong case for the recognition of A. appalachiana as a distinct species of bamboo. They submitted their evidence in a manuscript to the scientific journal Sida, Contributions to Botany, convincing the peer reviewers that the bamboo they discovered was new. Their study was publishe...

What recognizes what in plant disease resistance?

...ce. Contrary to current models, which propose that recognition of resistance genes occurs solely through their leucine-rich repeat domain, the authors show that association is mediated by a completely different region on N's Toll-interleukin-1 receptor homology domain, which is structurally similar to animal inn...

Rewarding fat rats

... to 19. "It's an honour to receive this sort of recognition from one's peers, and I do feel proud," says Shizgal, a Concordia University professor of psychology. "That pride should be shared. Achievements like this in the natural sciences often reflect the work of a team, and that is certainly true in my case...

Health Canada approves cold and flu medicine

...trials. “This is our strongest point of medical recognition to date, and coming from the government authority whose responsibility it is to help Canadians maintain and improve their health, this approval should give great confidence to consumers,?said Dr. Jacqueline Shan, co-founder of CV Technologies, a Univ...

"But more U.S. businesses should invest in these wellness programs. Once employees are given the tools to better understand and manage their pain successfu...

Nobel Laureate finds 'elegant' explanation for DNA transcribing enzyme's high fidelity

... The trigger loop mechanism therefore couples NTP recognition and catalysis, ensuring the fidelity of transcription, they reported. “Of all revelations from the structure [of the transcription machinery] since it was first solved, this is perhaps the most fundamental since it gets at the underlying mechanisms...
