Alzheimer's disease is not accelerated aging

...her typical aging and Alzheimer's disease are on a continuum or distinct," explained lead author and HHMI research associate Denise Head. The researchers used MRI to measure the volume of two regions of the brain previously linked with age-associated changes: the corpus callosum, and the medial temporal lobe. ...

Risk of preeclampsia rises sharply with increased pre-pregnancy body mass index

...method of calculating percentage of body fat) as a continuum rather than simply by conventional classification units. It also is the first study to try to determine the mechanisms by which body fat increases preeclampsia risk. Preeclampsia affects about 7 percent of first pregnancies nationwide, and is charact...

New study of land use effects on amphibian populations gets underway at UGA laboratory

...omly assigned a different treatment representing a continuum of disturbance: 1) complete clearing with coarse woody debris (CWD) removed, 2) clearing with coarse woody debris retained, 3) partial cutting (e.g., thinning), or 4) uncut forested control. Quadrants will be allowed to undergo succession in subseque...

An unexplored genomic terrain in a handful of dirt

...es. Now, we might rethink that classification as a continuum of genes that are predominantly bacterial or phage." The researchers' findings also suggest how phages mix their genes to produce the widely varied "mosaic" structure of their genomes. One theory posits that the genomes possess specific "linker" sequ...

Patients with the poorest glycaemic control (HbA1c level 11%) experienced the greatest reduction in HbA1c levels (-2.2% Xenical vs -1...

Biting may drive division of labor among social wasp workers

...cape. "These are not different behaviors but a continuum of the same behavior, and the intensity of biting can transition to a more aggressive form," said O'Donnell. In addition, he observed that some individuals were the victims of simultaneous or serial biting. As many as six wasps were observed bit...

The little protein that could

This doesn't mean that we can start manipulating people's genes, putting more metallothionein in their genetic mak...

Human-Like Ability, Categorical Perception, Found In Insects

...'pa,' " Wyttenbach noted. "Even though there is a continuum of variation between 'ba' and 'pa' based on voice onset time or VOT, which instruments can detect, our ears don't discriminate. We hear either 'ba' or 'pa' and that's how we label it. That is categorical perception, and it looked like crickets migh...
