Male circumcision reduces risk of HIV transmission from women to men

...ers has found that uncircumcised men have morethan twice the risk of acquiring HIV than do circumcised men.In the study, published in the Feb. 15 issue of The Journal ofInfectious Diseases, now available online, Jared Baeten and colleaguesfrom the United States and Kenya collected detailed sexual data from...

New Study from Affymetrix Laboratories Points to Changing View of How Genome Works

...osine nucleotides (non-polyA) at the tail-end were twice as common as the more well-studied RNAs that have this sequence. Most transcripts derived from the sparsely transcribed regions between centers of dense transcription are non-polyA transcripts. This study focused on an in depth scan of 10 chromosome...

Taking Aim With Nanoparticle PEBBLEs

...ailored to home in on cancer cells, the rats lived twice as long. With targeted PEBBLEs, some rats were still alive and active two months later, and MRI images showed that their tumors had vanished. Kopelman and coworkers plan to tinker with the PEBBLEs a bit more before trying them on larger numbers of r...

Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed

...e computer reconstructions indicate it was perhaps twice as thick at the end of the last ice age, also called the Last Glacial Maximum. But evidence from an ice core extracted near Siple Dome from 1997-99, along with other calculations, indicates ice in that area has lost only 200 to 400 meters of its thi...

The very unexpected life and death of a leukemic cell

...vy water is made using a form of hydrogen that has twice its normal mass, making the water molecule "heavier" than normal. The special hydrogen serves as a tag that enables researchers to track the utilization of water in the body. The hydrogen incorporates into glucose and the tagged glucose eventually ma...

New RNA polymerase discovered in plants

...culation that this form of polymerase might extend twice as far back in evolution,' Pikaard said. Pikaard said that it is strange that so far this kind of polymerase has been found only in plants. "Why would plants only have these?" he questioned. "It is a bit of a mystery how other organisms that use sm...

Youth With HIV Take More Risks After New Meds Introduced

...istics. The 1999-2000 post-HAART group was almost twice as likely as the pre-HAART group to have had unprotected sex in the last three months. On average, post-HAART youth had nearly double the sexual partners as pre-HAART youth. Post-HAART youth were also more likely to have had a sexual partner who used...

Nanoparticle Breast Cancer Drug Approved by FDA

... all participants treated with Abraxane was almost twice that of participants receiving the solvent-based paclitaxel injection. Without toxic solvents, Abraxane could be given at higher doses than Taxol, which may account, in part, for the increased anti-tumor activity. In addition, albumin is a protein t...

Brain Scans Reveal How Gene May Boost Schizophrenia Risk

...e NIMH researchers scanned 24 healthy young adults twice using PET (positron emission tomography), which uses radioactive tracers to visualize brain function. The first scan measured subjects' overall brain activity while they performed working memory tasks. The second scan used a dopamine tracer to reveal...

Maine Researchers Find Exceptions to Old Rules of Genetic Inheritance

Stranger still, male and female mice that inherit the t haplotype from both parents typically do not survive, but in the rare instances when they do, the overwhelming majority of males are sterile. Until now, most genetici...

Signs of aging: Scientists evaluate genes associated with longevity

...ificantly extended lives, persisting approximately twice as long as their wild-type counterparts. Daf-2 was first reported as a critical aging-associated gene in 1993, but since that time, scientists have identified dozens of additional genes that are crucial for longevity. "Aging is a complex process," e...

Man-made wetland's effectiveness similar to natural marsh

The researchers also gathered data on water flowing into the wetland from rain and snowfall and from ground sources. They wanted to know if t...

Researchers reveal secrets of flying snakes

Most flying snakes grow 3 to 4 feet long and live in the trees in the lowland tropical rainforests of South and Southeast Asia. Their temperament varies f...

Studies reveal how plague disables immune system, and how to exploit the process to make a vaccine

"Our data, the authors conclude, "provide the first evidence of plague vaccines that do not suppress innate immune responses ?and that...

Their unraveling of the genome also allowed Rolf Olsen, a postdoctoral fellow working in Loomis' laboratory, to generate a tree of life and show that amoebozoa, the group to which Dictyostelium belongs, evolved from the...

University of Nevada, Reno research team discovers hormone that causes malaria mosquito to urinate

...regnant female mosquitoes do this--it will take in twice its body weight in blood. To decrease this added weight, the mosquito urinates on its victim to release fluids. Coast discovered that introducing one of the two diuretic hormones, DH31, into the mosquito causes the mosquito to excrete fluid rich in...

The authors rank desertification ?land degradation in drylands as a result of climatic factors and human activities ?among the world's greatest environmental challenges, destabil...
