Malaria vaccine candidate, RTS,S reduces the risk of malaria by half in African children

CHAPEL HILL, N.C. — First results from a large-scale Phase III trial of RTS,S*, published online today in the New England Journal of Medicine (NEJM), show the malaria vaccine candidate to provide young African children with significant protection against clinical and severe malaria with an acceptable safety and tolerability profile. The results were announced today at the Malaria Forum hosted by the Bill & Melinda Gates Foundation in Seattle, Washington.

Analyzing the sheep genome for parasite resistance

Genetic resistance to a parasitic nematode that infects sheep has been discovered by a team of scientists with the U.S. Department of Agriculture (USDA) and the International Livestock Research Institute (ILRI).

Cells are crawling all over our bodies, but how?

For better and for worse, human health depends on a cell's motility –– the ability to crawl from place to place. In every human body, millions of cells –are crawling around doing mostly good deeds ––– though if any of those crawlers are cancerous, watch out.

Scientists create computing building blocks from bacteria and DNA

Scientists have successfully demonstrated that they can build some of the basic components for digital devices out of bacteria and DNA, which could pave the way for a new generation of biological computing devices, in research published today in the journal Nature Communications.

Forgetting is part of remembering

It's time for forgetting to get some respect, says Ben Storm, author of a new article on memory in Current Directions in Psychological Science, a journal of the Association for Psychological Science. "We need to rethink how we're talking about forgetting and realize that under some conditions it actually does play an important role in the function of memory," says Storm, who is a professor at the University of Illinois at Chicago.

Lab meat and synthetic blood - mapping the future course of stem cell research

Vampires on the "True Blood" television series are already enjoying the advantages of synthetic blood. While this may seem to be only the imagination on the big screen, the true benefits of blood manufactured from embryonic stem cells may be less than a decade away.

Light dependency underlies beneficial jetlag in racehorses

A new study has shown that racehorses are extremely sensitive to changes in daily light and, contrary to humans, can adapt very quickly to sudden shifts in the 24-hour light-dark cycle, such as those resulting from a transmeridian flight, with unexpected benefits on their physical performance.

The research led by academics in the University of Bristol's Faculty of Medical and Veterinary Sciences is published in the Journal of Neuroendocrinology.

Unknown species and larval stages of extremely long-legged beetles discovered by DNA test

The research program AQUA Palawana has been exploring the unique freshwater biodiversity of the Philippine Island and biosphere reserve of Palawan for more than a decade.

Respiratory distress syndrome: Primary killer of premature infants get some new treatments

A discovery by scientists at the Salk Institute for Biological Studies might explain why some premature infants fail to respond to existing treatments for a deadly respiratory distress syndrome (RDS) and offers clues for new ways to treat the breathing disorder.

Shift work in teens linked to increased multiple sclerosis risk

Researchers from Sweden have uncovered an association between shift work and increased risk of multiple sclerosis (MS). Those who engage in off-hour employment before the age of 20 may be at risk for MS due to a disruption in their circadian rhythm and sleep pattern. Findings of this novel study appear today in Annals of Neurology, a journal published by Wiley-Blackwell on behalf of the American Neurological Association and Child Neurology Society.

High rate of false-positives with annual mammogram

During a decade of receiving mammograms, more than half of cancer-free women will be among those summoned back for more testing because of false-positive results, and about one in 12 will be referred for a biopsy.

Simply shifting screening to every other year lowers a woman's probability of having one of these false-positive episodes by about a third – from 61 percent to 42 percent – over the course of a decade.

Researchers find possible link between bacterium and colon cancer

BOSTON¬—Scientists at Dana-Farber Cancer Institute and the Broad Institute have found strikingly high levels of a bacterium in colorectal cancers, a sign that it might contribute to the disease and potentially be a key to diagnosing, preventing, and treating it.

Muscling toward a longer life: Genetic aging pathway identified in flies

Researchers at Emory University School of Medicine have identified a set of genes that act in muscles to modulate aging and resistance to stress in fruit flies. Scientists have previously found mutations that extend fruit fly lifespan, but this group of genes is distinct because it acts specifically in muscles.

The results were published online this week by the journal Developmental Cell, findings which could help doctors better understand and treat muscle degeneration in human aging.

Immune peacekeepers discovered

Sydney: Tuesday 18 October 2011 -- There are more bacteria living on our skin and in our gut than cells in our body. We need them. But until now no-one knew how the immune system could tell that these bacteria are harmless.

Centenary Institute researchers in Sydney have discovered a set of peacekeepers—immune cells in the outer layers of our skin that stop us from attacking friendly bacteria.

The work will open the way to new therapeutic options for immune-mediated diseases such as inflammatory bowel disease, of which Australia has some of the world's highest rates.

New research links common RNA modification to obesity

An international research team has discovered that a pervasive human RNA modification provides the physiological underpinning of the genetic regulatory process that contributes to obesity and type II diabetes.

European researchers showed in 2007 that the FTO gene was the major gene associated with obesity and type II diabetes, but the details of its physiological and cellular functioning remained unknown.
