New study is first to link romantic relationships to genes

...es increased, womens' sexual responsivity to their partners decreased, their number of extra-pair sexual partners increased and their attraction to men other than their primary partners increased, particularly duri...

UCSF study will test new vaginal microbicide for herpes and HIV

...selves from infection rather than relying on their partners to use condoms. "The significance of the gel is that it potentially gives the power back to the woman to protect herself against infection," said Anna-Barbara Moscicki, MD, professor of pediatrics at UCSF and lead investigator for the study. T...

...CD devices. They are part of a consortium of nine partners and supported by the Resource Efficiency Knowledge Transfer Network (KTN) and the Displays and Lighting Knowledge Transfer Network. The DTI will fund 50% of a total bid worth £1.7 million. Welcoming the research, Science and Innovation Minister, Lo...

Heavy smoking cuts women's chance of pregnancy -- even with donated oocytes

...heavy smokers (over 10 a day). None of the women's partners were smokers and none of the oocyte donors were heavy smokers. The two groups of recipients were comparable and the number of embryos transferred in each cycle (between one and three) was also comparable between the groups. Lead researcher Dr Sérg...

Male circumcision reduces HIV risk, study stopped early

...nfections, and less risk of cervical cancer in the partners of circumcised men." The armamentarium of HIV prevention strategies is very small, according to Bailey. The only other strategy proven effective is the use of antiretroviral drugs to reduce transmission from mother to child. If a significant p...

'Tribbles' protein implicated in common and aggressive form of leukemia

... Tribbles by chance when looking for the molecular partners of another protein called Notch. Notch is a molecular switch of sorts, activating gene transcription in the nucleus of many types of cells, and depending on the biochemical context, turns certain pathways on and others off. Pear and colleagues kn...

PNAS study reveals why organs fail following massive trauma

...o T cell post-trauma dysfunction, and their likely partners in signaling pathways. The final step was to demonstrate that the proteins associated with those genes have an actual role in organ failure via real-world biochemical tests. Results showed that the expression of nearly 5,700 genes related to T cell...

Blue eyes -- A clue to paternity

... men were the group with the largest proportion of partners of the same eye color. According to Bruno Laeng and colleagues, "It is remarkable that blue-eyed men showed such a clear preference for women with the same eye color, given that the present experiment did not request participants to choose prospec...

Complexity constrains evolution of human brain genes

...rain. "We know that proteins with more interacting partners evolve more slowly," Wu said. "Mutations that disrupt existing interactions aren't tolerated." Although the gene sequences from human and chimpanzee remain very similar, previous studies in tissues other than the brain have shown that gene express...

Solvent exposure linked to birth defects in babies of male painters

...ers employed as painters three months before their partners became pregnant were on average six times more likely than the carpenters to father congenitally malformed babies (e.g. defects of cardiovascular, gastrointestinal, urogenital and central nervous systems.) In addition, the painters exposed to the ...

Nice guys do finish first in lizards' evolutionary race

... working to pass on their genes, even though their partners aren't family. The tag-team approach does effectively thwart the orange-throat bullies, albeit at a personal cost. The term "greenbeard" refers to an evolutionary term of a trait so obvious that others can recognize The greenbeard in this case, McAd...

Robots manipulating animal behaviour

...ough the project has officially ended, some of the partners are continuing to refine the behaviour models they developed. The main research results are also being published in leading IT and biology journals. "Time constraints prevented us from exploring all the new and interesting research paths that opened ...

Tigers get a business plan

...r working closely with local governments and other partners to gain baseline knowledge on tigers in places like Myanmar's Hukawng Valley ?the world's largest tiger reserve ? while stepping up anti-poaching activities in other sites, including Thailand's Huai Kha Khaeng and Thung Yai protected areas. In some...

The brain, traffic and nano-circuits -- e-Science takes on major challenges

...ciences Research Council (EPSRC) and other funding partners have awarded more than £13m to three, 3-4 year projects covering each of these topics in the third round of the EPSRC's e-Science programme. e-Science is opening up to scientific scrutiny challenging problems that had seemed out of reach, or even im...

Gut microbes' partnership helps body extract energy from food, store it as fat

...ot have the genes needed to digest them. Bacterial partners living in our colons, such as Bacteroides thetaiotaomicron, begin a fermentation process that breaks down these nutrients so that the stored calories can be liberated and absorbed. But B. thetaiotaomicron doesn't just work in a simple partnership ...

Smell of success for nanobiosensors

In this sense, new high accuracy electronic ins...

Flick of whiskers helps tease out brain's 'shadow' signaling system

...ack and forth, indicating that astrocytes are full partners in the basic working of the brain. "Our take on this is that astrocytes really are part of higher brain function," said Nedergaard, noting that astrocytes are much more complex in people than in rodents, while neurons aren't that much different ?jus...
