Tropical birds sensitive to environmental cues that can be impacted by global warming

...e to global warming could have "effects we haven't thought of before." While Moore's research was driven primarily by curiosity and not by conservation concerns, "you can't save things if you don't understand them," he said. "Every little bit of knowledge about how things works is useful." They will next try...

Ancient fossil offers new clues to brown bears past

...theus. "Those bears belong to a genetic population thought to be extinct in North America for as much as 35,000 years." Consequently, paleontologists and geneticists have found it difficult to explain where the ancestors of southern brown bears came from when ice sheets retreated about 13,000 years ago--th...

Scientists advocate genomic sequencing of 'living fossil'

...f the defining characteristics of coelacanths, are thought to represent an intermediate evolutionary stage in the transformation of fins to limbs. Lobe-finned relatives of the coelacanth underwent morphological alterations that enabled them to emerge from the sea and inhabit terrestrial environments. Both ...

UCLA scientists uncork fountain of youth for HIV-fighting cells

...ing telomerase's growth influence on telomeres, we thought we might be able to keep the immune cells youthful and active as they replicated under attack," said Dagarag, a postgraduate researcher. "We used gene therapy to boost the immune cell's telomerase and then exposed the cell to HIV." What Dagarag and ...

Sperm enzyme is essential for male fertility, study shows

...zed cellular structures known as mitochondria were thought to provide a substantial portion of the ATP needed for sperm motility. In contrast, Dr. Deborah A. O'Brien, associate professor of cell and developmental biology at UNC's School of Medicine, and her colleagues found that sperm motility and ATP produc...

In a parallel study, Medin and his colleagues were able to monitor gene therapy vector activity in treated live mice at vario...

Free radicals are thought to be a fundamental cause of many degenerative diseases and the aging process and can be produced naturally in the body over time, or they can be caused by environmental factors--such as air pollution, cigarette smoking, and pesticides. Antioxidants,...

Concord grape juice increased HDL, lowered inflammatory marker linked to heart disease

We have seen in previous studies of healthy subjects that drinking grape juice decreases superoxide production and inhibits platelet aggregation, yet its impact on the in...

A puzzle posed by black-headed ducks yields to persistent biologists

...cted by Weller over three decades ago. It had been thought that they exploited a wide range of host species, but Lyon and Eadie found that the ducks focused their parasitic efforts on the two species of coots, only occasionally laying eggs in the nests of other species. Thus, black-headed ducks appear to be ...

The researchers' data also reveal that after feeding resumes, the phospholipid levels in heart muscle cells rise back to normal levels, indicating that mitochondria readily rebuild their membran...

Although synesthesia is thought to occur in just 1 per cent of all adults, in her keynote address at the annual meeting of the American Synesthesia Association November 6, Maurer discussed evidence that all infants are synesthetic.

Using an African wild silk moth and its natural enemies as a case study, a new analytical technique was applied to the problem. The result...

New findings in innate immunity may lead to treatments for atherosclerosis

"In the past," says Dr. Li, "it was thought that all IRAKs may play a somewhat redundant role in regulating the nuclear transcription factor NFκB and the expression of pro-inflammatory cytokines such as IL-1beta and TNFalpha." However, mice that lack IRAK1 can still activate NFκB, su...
