Perfect peas to push profits and cut carbon
Scientists, pea breeders and the food industry are collaborating to discover how taste and tenderness can be determined by biochemistry and genetics.

Snake venom charms science world
The king cobra continues to weave its charm with researchers identifying a protein in its venom with the potential for new drug discovery and to advance understanding of disease mechanisms.

Vitamin D crucial to activating immune defenses
Scientists have found that vitamin D is crucial to activating our immune defenses and that without sufficient intake of the vitamin, the killer cells of the immune system -- T cells -- will not be able to react to and fight off serious infections in the body.

Pioneering treatment reduces disability in premature babies with serious brain hemorrhage
A pioneering technique, a world first in Bristol, has been shown to reduce disability in premature babies with serious brain hemorrhage by washing the brain to remove toxic fluid.

Women's group support can improve birth outcomes
Community support groups can reduce neonatal mortality, and lower rates of maternal depression-provided that the population coverage is wide enough and the programs are appropriately designed.

MIT researchers discover new way of producing electricity
A team of scientists at MIT have discovered a previously unknown phenomenon that can cause powerful waves of energy to shoot through minuscule wires known as carbon nanotubes.

Asking 'what would nature do?' leads to a way to break down a greenhouse gas
A recent discovery in understanding how to chemically break down the greenhouse gas carbon dioxide into a useful form opens the doors for scientists to wonder what organism is out there -- or could be created -- to accomplish the task.

Repeated anesthesia can affect childrens ability to learn
There is a link between repeated anesthesia in children and memory impairment, though physical activity can help to form new cells that improve memory, reveals new research from the Sahlgrenska Academy at the University of Gothenburg, Sweden.

Gene site found for children's food allergy
Pediatrics researchers have identified the first major gene location responsible for a severe, often painful food allergy called eosinophilic esophagitis (EoE).

New sensor array detects single molecules for the first time
MIT chemical engineers have built a sensor array that, for the first time, can detect single molecules of hydrogen peroxide emanating from a single living cell.

All may look smooth, but there are 'bumps' along the way
Friction in human relations is all too obvious and prevalent, but friction in physics has had a

New species discovered on the Great Barrier Reef
Between the grains of sand on the sea floor there is an unknown and unexplored world.

New cases of genocide often denied after Holocaust
Experiences from the Holocaust led to the international community coming together and agreeing on the Convention on the Prevention and Punishment of the Crime of Genocide.

Climate issue a matter of solidarity and economic opportunities
Sweden opted for a more ambitious target than obliged to under the Kyoto Protocol, since the climate issue was perceived as an economic opportunity.

Women's support groups make dramatic improvements on neonatal survival rates
Women's community groups have had a dramatic effect on reducing neonatal mortality rates in some of the poorest areas on India, according to a study published today in the journal the Lancet.

A high-tech handrest
University of Utah engineers developed a computer-controlled, motorized hand and arm support that will let doctors, artists and others precisely control scalpels, brushes and tools over a wider area than otherwise possible, and with less fatigue.

Ritalin boosts learning by increasing brain plasticity
Doctors treat millions of children with Ritalin every year to improve their ability to focus on tasks, but scientists now report that Ritalin also directly enhances the speed of learning.

MIT scientists transform polyethylene into a heat-conducting material
Most polymers -- materials made of long, chain-like molecules -- are very good insulators for both heat and electricity.

Khirbet Qeiyafa identified as biblical 'Neta'im'
Has another mystery in the history of Israel been solved?

An improved method for calculating tumor growth
When treating cancer, it is an advantage to know the rate of growth of the cancer tumor.

NIAID media availability: Food allergy-related disorder linked to master allergy gene
Scientists have identified a region of a human chromosome that is associated with eosinophilic esophagitis, a recently recognized allergic disease.

Breastfeeding protects children against peptic ulcer bacterium
Young children in developing countries are infected at an early age with the bacterium Helicobacter pylori, which can cause peptic ulcers and stomach cancer.

CSHL-Mexican team coaxes sexually reproducing plant to brink of asexual reproduction
In a paper to appear online in Nature February 7, plant geneticists at Cold Spring Harbor Laboratory and the National Polytechnic Institute in Mexico report moving a step closer to the goal of turning plants that normally reproduce sexually into asexual reproducers, an outcome that would have profound implications for agriculture globally.

Mathematical innovation turns blood draw into information gold mine in Stanford study
Scientists at the Stanford University School of Medicine have devised a software algorithm that could enable a common laboratory device to virtually separate a whole-blood sample into its different cell types and detect medically important gene-activity changes specific to any one of those cell types.

How to fortify the immunity of HIV patients
New findings from a Université de Montréal and the Vaccine and Gene Therapy Institute of Florida study, in collaboration with scientists from the NIH and the McGill University Health Center, may soon lead to an expansion of the drug arsenal used to fight HIV.
