Physicists have long wondered how the properties (including spin) of protons and neutrons inside an atomic nucleus can be explained in terms of quarks, their most elementary particles.

Independent study: DEET products superior for fending off mosquito bites
In a new comparative study of insect repellents containing the chemical commonly known as DEET and plant-based repellents, products with DEET showed by far the greatest effectiveness in preventing mosquito bites, medical researchers say.

New scanner holds promise of better breast cancer detection
A new high-resolution nuclear medicine imaging scanner specifically designed for breast exams could increase physicians' ability to determine if a woman has breast cancer.

Exercising at particular times in the menstrual cycle could help women to lose more weight, according to new Australian research.

American Thoracic Society Journal news tips for July (first issue)
Journal newsworthy highlights include: research showing how ambient levels of air pollution produced significant deficits in children's lung function growth rates; despite five published retrospective studies claiming the opposite result, investigators in the first prospective research on antibiotic use in the first year of life found no association with asthma at age 5; and tuberculosis (TB) patients who recognized photos of other patients in their TB cluster pointed up common transmission sites.

Stanford scientists flick genetic switch; may lead to new disease treatments
Genes that are inappropriately turned on play a critical role in triggering some diseases.

Women cured of childhood leukaemia should be advised to have children while they are young
Women who have survived having leukaemia as children should receive fertility counselling because their reproductive life may be shortened even though they have an apparently normal menstrual cycle after treatment, according to Danish researchers.

NSF is establishing three new research institutes that will help strengthen the mathematical sciences as the backbone for U.S. scientific and engineering research.

The 'forbidden' questions on genetic testing
With UK insurance companies currently prohibited from asking questions about genetic tests, researchers are seeking to discover the potential impact of genetic testing on insurance costs and the interaction between genetic testing and insurance buying.

First pregnancies reported using a new, needle-free device for administering hormones to IVF women
Fear of needles and the discomfort of daily injections could soon be a thing of the past for women undergoing IVF treatment thanks to a new device which can administer hormones without a needle injection.

Jefferson Lab free-electron laser upgrade could induce completely new phenomena in materials
The newly upgraded Jefferson Lab Free-Electron Laser will have the capability of delivering 10,000 watts of infrared light to a material.

Alignment key to knee surgery success
Just as failing to perform an alignment on a car after installing a new tire will lead to uneven wear and tear and ultimately tire failure, performing knee surgery without taking into account the proper alignment of the leg bones above and below the joint could cause future problems including degenerative arthritis , according to a new study by Duke University Sports Medicine researchers.

Muscle stem cells show promise against muscular dystrophy in mouse model
Scientists have isolated special muscle-generating stem cells that can improve muscle regeneration and deliver the missing protein dystrophin to damaged muscles in a mouse muscular dystrophy (MD) model, according to a study supported in part by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS).
