"Talking" helps computer programs develop better hunting strategies
An NEC Institute/Penn State study shows that computer programs, known as autonomous agents, not only can evolve their own language and talk with one another, but also can use communication to improve their performance in solving the classic predator-prey problem.

Area of brain found to play key role in initiating memory storage
Flee, freeze or fight. A response to a threat is based on experience and memory.

Vinegar plus HPV test identifies women at risk for cervical cancer
A lab test for the human papilloma virus (HPV) combined with a visual inspection of the cervix could identify pre- cancerous lesions and vastly reduce the number of false positives among women at high risk for cervical cancer in developing countries, according to researchers at Johns Hopkins and the University of Zimbabwe.

Medical imaging with 'Swiss Rolls'
A novel magnetic material developed by British researchers may lead to dramatic improvements in the performance of Magnetic Resonance Imaging (MRI) systems.

'The Little Book of Stars' is very big on science
What are stars? How do they shine? How are stars born and what makes them die?

Problem drinking may affect adherence to HIV medication
An under-recognized phenomenon may affect medication adherence among individuals with HIV -- problem drinking, according to a study.

Chandra observations reveal X-ray glint in Cat's Eye Nebula
Hot gas from a shocked stellar wind is responsible for the complex shape of a planetary nebula known as the Cat's Eye, say astronomers using NASA's Chandra X-ray Observatory.

New superconducting magnet to probe proton structure
To help unlock the innermost secrets of the proton, a doughnut-shaped superconducting magnet 14 feet in diameter is now being tested at the University of Illinois.

Non-steroidal anti-inflammatory drugs are associated with increased risk of miscarriage in pregnant women
Taking non-steroidal anti-inflammatory drugs during pregnancy does not seem to increase the risk of adverse birth outcome (congenital abnormality, low birth weight, or preterm birth) but is associated with increased risk of miscarriage, according to a study in this week's BMJ.

Mosquito nets treated with insecticide and distributed as part of a large scale social marketing programme can substantially reduce the prevalence of malaria and anaemia in very young children in Tanzania, finds a study in this week's BMJ.

Legumes found to contain starch carrying a fiber-like punch
Legumes often fall far below popular grains and moisture- laden fruits and vegetables on the list of foods Americans eat to try to meet the American Dietetic Association- recommended 25 to 35 grams of dietary fiber per day.

Geological Society of America and Geological Society of London to co-convene "Earth System Processes"
Major themes of this broad, interdisciplinary meeting are Earth systems linkages (relationships among solid Earth, the hydrosphere, atmosphere, cryosphere, and biosphere) and Earth system evolution (ways in which processes controlling the nature of the planet have evolved through time).

Fighting breast cancer at the molecular level
Using molecular-biology techniques, LSU scientists hope to develop tests that could detect individual cancer cells, allowing doctors to diagnose cancer before tumors are large enough to be felt or seen on mammograms.

Morphine spray more effective than injection to relieve pain in young people
Nasal diamorphine spray is a safe and effective method of pain relief for young people in acute pain with a limb fracture, and should be used in place of morphine by intramuscular injection, finds a study in this week's BMJ.
