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

... 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," explains Weill Cornell Medical College molecular biologist a...

Study investigates 'divorce' among Galapagos seabirds

...r, his mate is likely to choose another. A male’s capacity to raise offspring, a quality that can vary with time, may carry more weight with a mate than stellar genes or past breeding success, Maness said. She used 14 years of data on about 950 males and 700 females in the study. During that time, the maj...

Research finds that circadian rhythms dominate all life functions

...State study uses advanced algorithms that have the capacity to identify patterns in such a large number of genes. Ptitsyn discovered that gene activity oscillates in a "finely orchestrated" system and gene expression can be impacted by daylight and darkness -- or a lack of both. For example, while gene exp...

Researchers use MRI to predict recovery after spinal cord injury

Automatic identification of protein's critical features from the structure

...d by other reasons than fashion. In biology, the capacity to establish the function of a molecule, proteins in particular, from its form is relevant to understand how living forms work, and to develop effective treatments and diagnostic tests. The scientists led by Dr. Gabriel del Río at the Instituto d...

Implanting dopamine generators in brain cells obtains improvement in Parkinson's in monkeys

...meliorate Parkinson's appears to be related to the capacity of these cells to release substances (trophic factors) that induce an increase of the dopaminergic cells (that usually exist in the normal brain but in lower quantities). Amongst these trophic factors is the GNDF (Glial Cell-derived Neurotrophic Fact...
