Gene :: With fruit fly sex, researchers find mind-body connection

The fruit fly gene “doublesex” is responsible for ensuring that male flies look male and females look female. New Brown University research led by biologist Michael McKeown shows that doublesex not only helps shape bodies but also shapes behavior, acting with together with the gene “fruitless” to guide flies’ courtship routines and responses. The finding, published in Nature Genetics, shows that sexual development in flies — and, perhaps, in humans — is a more complicated proposition than previously thought.

Gene :: Living view in animals shows how cells decide to make proteins

Scientists at Duke University Medical Center have visualized in a living animal how cells use a critical biological process to dice and splice genetic material to create unique and varied proteins.

Rhythm :: New study suggests speakers of different languages perceive rhythm differently

Do the sounds of our native languages affect how we hear music and other non-language sounds? A team of American and Japanese researchers has found evidence that native languages influence the way people group non-language sounds into rhythms.

Wheezing :: Infants wheeze less in homes with multiple dogs

Living in a home with multiple dogs may help reduce an infant’s risk for developing wheezing in the first year of life, according to new research from the University of Cincinnati (UC).

Chemotherapy :: Chemo drugs harmful to healthy brain cells

Drugs used to destroy cancer cells may actually be more harmful to healthy cells in the brain, research suggests, done by a team from New York’s University of Rochester. They found several types of key brain cell were highly vulnerable to the drugs.

Cell death following blood ‘reflow’ injury tracked to natural toxin

Researchers at Johns Hopkins have discovered what they believe is the “smoking gun” responsible for most tissue and organ damage after a period of blood oxygen loss followed by a sudden restoration of blood oxygen flow.

Rosetta warms up for Mars swing-by

This month the team working on ESA’s Rosetta mission have been particularly busy. Activities are underway to set the spacecraft’s trajectory and prepare the on-board instruments ready for the next major mission milestone: the swing-by of planet Mars in February 2007.

New information technologies to tackle isolation on campus

Integrating new location-aware computer networks with old-fashioned human networks, researchers at the New Jersey Institute of Technology (NJIT) have developed an innovative solution to the problem of isolation that faces women in the academic science and engineering workforce.

Cancer :: What cures your aches might prevent cancer

Mayo Clinic Cancer Center has begun three clinical studies looking at the use of nonsteroidal anti-inflammatory drugs (NSAIDs) to prevent cancer — colon, esophageal or lung.

Exercise :: Low impact aerobic exercise reduces fatigue in auto-immune conditions

People with auto-immune conditions like MS, arthritis and lupus can benefit from low impact aerobic exercise — including walking and cycling — that increases in intensity, duration and frequency. A review of studies between 1987 and 2006 shows that 12-week programmes that involved exercising for 30 to 60 minutes, three times a week, yielded the most effective results.
