HIV and malaria combine to adversely affect pregnant women and their infants

...egnancies become protected against PAM. Having HIV results in this loss of protection and makes them as susceptible as first-time mothers. To uncover how HIV affects PAM, Kain and his team collected samples from women in the first pregnancy as well as from women in their subsequent ones living in the Ken...

New research shows sharks use their noses and bodies to locate smells

...and seawater plumes, let alone targets. "These results demonstrate for the first time that sharks require...ormation from their lateral line is essential. The results are interesting for our understanding of animal navigation under water and for the development of gu...

First confirmed common genetic risk factors for breast cancer

...iu said that the most immediate benefit of the new results may be in understanding the molecular mechanisms of breast cancer. The Nature paper is the second major research report published this year by this international team of scientists. In February of this year, the team reported in Nature Genetics th...

New study suggests potential for a broadly-protective HIV vaccine

...that will neutralize multiple viral strains. These results demonstrate that induction of truly broad-spectrum...on neutralized all 48 strains of HIV-1 tested. The results are encouraging for vaccine development, because they showed that it is possible to elicit a broad-s...

Mule deer moms rescue other fawns

... simply trying to protect their own fawns." The results appear in this month's issue of Animal Behaviour. In field trials using speakers that broadcast the calls of fawns under threat, the mule deer came to the speaker and stayed there as long as the calls played, twisting and turning as they confronte...

Lessons from the orangutans: Upright walking may have begun in the trees

...this may have an energy-related advantage. "Our results suggest that bipedalism is used to navigate the smallest branches where the tastiest fruits are, and also to reach further to help cross gaps between trees," said Thorpe. The authors propose an evolutionary scenario that begins as other researcher...

Moths mimic sounds to survive

...havior learned in the wild would not influence the results of the experiment. Barber said anecdotal observations have suggested that animals such as snakes, owls and bees use acoustic mimicry. This study takes the next step and provides the definitive experimental evidence for how mimicking sounds help...

Statin treatment improves spatial memory in mouse models of Alzheimer's

...tin improved memory in both males and females, the results were more pronounced in males. Dr. H. A. Morcos, chair of Pharmacology at the American University of Antigua, and colleagues at Florida A & M University presented the study April 30 at Experimental Biology 2007 in Washington, DC. His presentatio...

Climate change was the cause of Neanderthal extinction in the Iberian Peninsula

...d in the knowledge of human ancestral history. The results of this multidisciplinary research are an important contribution to the understanding of the Neanderthal extinction and the colonisation of the European continent by Homo Sapiens. During the last Ice Age, the Iberian Peninsula was a refuge for Nea...

Does amateur boxing cause brain damage?

...ly damaging to the central nervous system, and our results suggest CSF-analysis could be used for medical counseling of athletes after boxing or head injury," said Hietala. The study was extended to soccer players heading the ball repeatedly from long and high goal kicks. No increased levels of biochemica...

'Personality-gene' makes songbirds curious

... object was a pink panther (see figure 2). The results from the group of selected birds were confirmed with data from free-living, unselected great tits. In the forest-living birds, the scientists also found a significant association between the SNP830-genotypes of individuals and variation in their leve...

Scripps research team sheds light on long-sought cold sensation gene

...ends a signal to the brain. The Patapoutian team’s results support the idea that activation of TRPM8 by temperature triggers cold sensation. "TRPM8 acts as a gate," says Dhaka, "At warm temperature it remains closed, but opens when exposed to cool temperature." The TRPM8-deficient mice did not lose their...

How the brain's backup system compensates for stroke

...earning of new motor strategies after brain damage results in the normal routes to action being compromised." The researchers concluded that their experiments showed that "In the initial stages of adaptive compensation for neuronal interference, the adult brain exploits pre-established patterns of functio...

Peramivir protects mice from lethal H5N1 infection

...ic of the avian influenza virus H5N1, according to results of mouse studies conducted by investigators at St. Jude Children's Research Hospital. Peramivir, an antiviral drug, blocks the ability of influenza viruses to use an enzyme called neuraminidase, thus preventing the release of new virus particles a...
