Scientists debate meaning of 40-million-year-old primate fossils in Nature

...ng. Seiffert and colleagues conclude that the new finds are compatible with the widely accepted view that the lorises and bushbabies (as a group) diverged from lemurs 50 million to 53 million years ago, and that their last common ancestor lived in Afro-Arabia. Martin's alternative interpretation stems fro...

A cholesterol-controlling drug could strike a blow against insulin resistance

...in resistant and hypertensive. An animal study now finds that stimulating NO bioavailability by lipid lowering statins may represent a new way to combat this epidemic. Statins are a group of compounds that have been used successfully to lower cholesterol and prevent myocardial infarction. A less well know...

Grape seed extract may be useful supplement to blunt hypertension in postmenopausal women

...lowering blood pressure. Now, a new research study finds that a diet moderately high in grape seed extract can blunt salt (sodium chloride)-sensitive hypertension to about the same extent as treatment with either plant estrogens or 17-estradiol. This suggests that mechanisms other than the estrogen recept...

Hebrew University excavations strengthen dating of archaeological findings to David, Solomon

Scientists break down patterns in nature

...f the insects feeding on the tree. The PNAS paper finds that abundances of pairs of species in terminal twigs behave in a very special way. "Just like two pieces of rock that once belonged together," Pimm says. "Take a rock and split it into two pieces. On average, the bigger piece will be three-quarters ...

Bread mold yields a genome first for filamentous fungi

...detects and mutates whole sections of DNA where it finds a duplication in the DNA, a condition thatotherwise often leads to the creation of new genes. The authors suggest that "RIP has a powerful impact in suppressing the creation of these new genes or partial genes" and it may have"virtually arrested" th...

When he finds them he homes in to investigate the very essence of simple creatures' ion channels that is consistently retained in more complex organisms." Model scientists, not magic "In almost every scientific forum," says MacKinnon, "someone always asks the qu...

Troubling news about sea otter deaths

A new UC Davis analysis finds that adult sea otters in California in 1998-2001 died in unusually high numbers from newly recognized diseases and in geographic clusters -- all of which suggest that their coastal environment may be so substantially altered that the species could be...

Pattern recognition method zeroes in on genes that regulate cell's genetic machinery

...The new approach described in Nature Genetics also finds clusters, but it is the first to incorporate data about known and putative regulatory genes and the first to simultaneously predict which gene or genes regulate each cluster. In response to internal or external signals, regulatory genes tell cluster...

Anti-HIV drugs save vision, improve outlook for AIDS patients

.... A second study led by Johns Hopkins researchers finds that among AIDS patients with longstanding vision problems, those who took HAART reported higher overall quality of life. The Johns Hopkins team reported in the April issue of Archives of Ophthalmology that AIDS patients who received HAART had a 75 ...

Few microbiological differences in households using antibacterials

...21, 2003 -- A microbiological survey of households finds little significant difference in levels of bacteria or antibiotic resistance between those that use antibacterial cleaning products and those who do not. Researchers from Tufts University School of Medicine report their findings today at the 103rd G...

Sporicidin disinfectant kills mold more effectively than bleach

...ricidin Disinfectant Solution and household bleach finds that Sporicidin is more effective than household bleach in controlling mold fungi (Stachybotrys and Chaetomium) on commonly used building materials (drywall). Sporicidin allowed no growth and provided continuous fungistatic activity for 4 months aft...

Short-term exposure to estrogen cuts fish fertility

...e ingredient in most oral contraceptives and often finds it way into surface waters through sewer systems. The PNNL study looked at the impact of a synthetic estrogen called ethynylestradiol, which is the chemical in oral contraceptives. Irvin Schultz, PNNL toxicologist who led the study, said the resear...

Hospitalized children experience medical errors at the same rate as adults

... Agency for Healthcare Research and Quality (AHRQ) finds that hospitalized children experience rates of medical errors similar to those of hospitalized adults. Based on 3.8 million pediatric discharge records from 22 states in 1997, or approximately 70 percent of all children hospitalized in the United St...

160,000-year-old fossilized skulls from Ethiopia are oldest modern humans

Volcanologist Richard S. Fiske receives award

.... Besides his major research projects, Dr. Fiske finds ways to convey his enthusiasm for volcanoes to the general public. In 1986, he helped arrange the production of the motion picture, Inside Hawaiian Volcanoes, by the late volcano cinematographer Maurice Krafft. Then, working with a colleague, he prod...

Unemployment, access to guns among factors that turn domestic violence deadly

...03 issue of the American Journal of Public Health, finds that a combination of factors, rather than a single factor, increases the likelihood that a woman will be murdered by her partner. Researchers identified and interviewed family members and acquaintances of 220 intimate partner femicide victims in 11...

Cold-climate creatures may be the ultimate survivors of global warming, study finds

In an experiment published in the July 4 edition of Science , Stanford University postdoctoral fellow Jonathon H. Stillman examined the effect of climate change on porcelain crabs (genus Petrolisthes) inch-long invert...

Science historians ponder naming 'enemies' in science literature

...ular context it is especially interesting that one finds almost no references to 'natural allies' in the literature, yet symbiosis is also a very common ecological phenomenon. Have we become so fixated on war, that we can only perceive nature through that lens?" Laubichler and Chew wonder....

UC Riverside is part of new initiative to share patented research on agriculture

... But the public research sector, the paper argues, finds itself increasingly restricted when wishing to develop new crops with the technologies it has itself invented, posing a barrier to the applications of biotechnology in the development of new crops. PIPRA 's immediate objectives are to review public ...
