Destructive enzyme shows a benevolent side

...nce that time. For this study, Schoenberg and a group of colleagues wanted to learn if the enzyme also destroys its mRNA during periods of stress. To answer the question, they used cultured cells to which they'd added active and mutant forms of the enzyme. They then stressed the cells using the chemi...

Phthalates now linked to fat, related health risks

... basis for the study, Stahlhut said. Stahlhut’s group hypothesized that phthalates might have a direct link to obesity, since low testosterone appears to cause increased belly fat and pre-diabetes in men. They analyzed urine, blood samples and other data from the National Health and Nutrition Examinatio...

Using brain scans, researchers find evidence for a two-stage model of human perceptual learning

...n these sessions, participants had to learn how to group the cars into two distinct categories. This was easy at first, Riesenhuber said, because the cars were obviously not alike, but then the researchers began to "tighten the screws" by making the two categories increasingly more similar. "Over the c...

Canadian study shows bilingualism has protective effect in delaying onset of dementia by four years

...e developed by Eva-Kathrin Sinner and her research group makes it possible, for the first time, to examine the natural functions of such membrane proteins in situ. This is of considerable importance to pharmaceuticals research, as it means that new active agent screenings can now be carried out using recep...

UBC researchers reveal dwarf aquatic plants' hidden ancestry

...wed Hydatellaceae as monocots, a large and diverse group of flowering plants that includes the grasses, gingers and palms. By analyzing the plants at the molecular level, Graham’s team has now determined that these moss-size plants are instead part of an older line of flowering plants that includes the wat...

Gene that makes people 'early to bed and early to rise' demystified

... the abnormal gene to exhibit symptoms. The UCSF group had earlier discovered a variant of the human Per2 gene that causes FASPS. They also showed that the so-called "S662G" variant, in which the serine building block normally present at position 662 is replaced by glycine, prevented a regulatory enzyme ...
