Virtual duck bills demonstrate species coexistence

...nd ingest. By avoiding particle sizes that contain too much detritus, ducks increase their foraging efficiency." However Gurd found that avoiding detritus reduces the rate at which ducks can filter water. "It is this trade-off between avoiding detritus and foraging rate that allows ducks to partition r...

Genes and genius: Researchers confirm association between gene and intelligence

...ct cognitive performance. Presently, she says it's too early to predict how small changes in the gene might be influencing communication in the brain to affect intelligence, and she says it's nearly certain CHRM2 is not the only gene involved. "Perhaps as many as 100 genes or more could influence int...

Vitamin D deficiency widespread during pregnancy

...sted at delivery had levels of vitamin D that were too low, even though more than 90 percent of them used prenatal vitamins during pregnancy," said Lisa Bodnar, Ph.D., M.P.H., R.D., assistant professor of epidemiology at the University of Pittsburgh Graduate School of Public Health (GSPH) and lead author...

Biologists call for better choice of model organisms in 'evo-devo'

Major link in brain-obesity puzzle found

...School researchers report. And although it’s far too early to say how this protein could be useful in new strategies to fight the world’s epidemic of obesity, the finding gives scientists an important system to target in future research and the development of anti-obesity medications. In the Februar...

'Exercise pill' switches on gene that tells cells to burn fat

...s so exciting, says Dr. Evans. In today’s society, too few people get an ideal amount of exercise, some because of medical problems or excess weight that makes exercise difficult. Having access to an "exercise pill" would improve the quality of muscles, since muscles like to be exercised, and increase th...

Chromosomal microarray analysis proves accurate

This high resolution genome analysis promise to transform the practice of clinical genetics," said Beaudet. More important, the technique found ab...

Investment level in HIV prevention programs related to HIV incidence in the United States

...ation) flattened out with little annual change, so too did the number of new infections per year. This suggested to the researchers that level investment yields level incidence. "Our analysis helps explain why the number of new HIV infections has remained at 40,000 per year for over 15 years," said Da...

Researchers show that veins stiffen as we age

However, several individuals already have been identified for the study, and the team hopes to have data to report in the next six months. ...

Gene key to taste bud development identified

...If there isn't enough SOX2 present, or if there is too much, the stem cells will not turn into taste buds." The researchers made their discovery in mice, but they believe the same process occurs in humans. According to the researchers, the findings will help scientists better understand how the behav...

"We see that diversity of species recovered dramatically, and with it the ecosystem's productivity and stabilit...

Proteins may predict lung transplant rejection

If doctors can predict which patients are beginning to reject the transplanted organ, they could try to head it off, she said. The study, "Proteomic biomarkers of chronic lung allograft rejection," was carried out by ...

Signal protein shows promise for blocking tumor promoters in skin cells

In skin cells, Src kinases and Srcasm are involved in signaling pathways that control cell growth and differentiation. See Saw Action The researchers decided to test whether Sr...

Why don't all moles progress to melanoma?

... fold these amino acids into specific shapes. When too many of them build up in the membrane, or when something goes wrong with the folding process, the system gets bogged down. This can stress or even kill the cell. To prevent this, the ER sends out distress signals to activate what scientists call t...

Some types of nephrotic syndrome can be treated with steroids or other drugs, but steroid-resistant forms of the disease as a rule do not respond to treatment. Untreated ne...
