Animals differ strikingly in character and temperament. Yet only recently has it become evident that personalities are a widespread phenomenon in the animal kingdom. Animals as diverse as spiders, mice and squids appear to have personalities. Personality differences have been described in more than 60 species, including primates, rodents, birds, fish, insects and mollusks.

New work by Max Wolf (University of Groningen; currently at the Santa Fe Institute), Santa Fe Institute Postdoctoral Fellow Sander van Doorn, Franz Weissing (University of Groningen), and Olof Leimar (Stockholm University) offers an explanation for the evolution of animal personalities.

Huge waves that struck Reunion Island and coastlines across Indonesia earlier this month all originated from the same storm that occurred south of Cape Town, South Africa, and were tracked across the entire Indian Ocean for some 10 000 kilometres over a nine-day period by ESA's Envisat satellite.

It seems almost certain that San Francisco Giants slugger Barry Bonds will pass Hank Aaron as baseball’s all-time home-run king sometime this summer, but his pursuit has generated little public interest.

There may be several reasons for this, ranging from Bonds’ prickly personality to the suspicion that he may have used performance-enhancing drugs later in his career, say two Duke University professors.

You might think it's something from the movie "Total Recall" but instead researchers are using brain "pacemakers" to regulate diseased signals in the brains of Parkinson's disease patients.

These devices are FDA-approved and in use in 30,000 patients but still not well understood.

Biomedical engineers at Duke University's Pratt School of Engineering have found that stimulation administered by rapid-fire electrical pulses deep in the brain produces what they call an "informational lesion." By relaying a repetitious and therefore meaningless message, constant pulses overwhelm the erratic bursts of brain activity characteristic of disease.

"Periodic bursts in the brains of people with tremor -- which might follow a pattern such as 'pop-pop-pop, silence, pop-pop-pop, silence' -- propa

How well do you know your child's pediatrician? Is he or she board certified in pediatrics, or has he or she ever completed specialty training in the field?

Findings from a new study from the University of Michigan C.S. Mott Children's Hospital's Child Health Evaluation and Research (CHEAR) Unit may prompt parents to find out if their child's physician really is who he claims to be – a board-certified and specialty-trained pediatrician.

The signature of climate change over the past 40 years has been identified in temperatures of the Indian Ocean near Australia.

"From ocean measurements and by analysing climate simulations we can see there are changes in features of the ocean that cannot be explained by natural variability," said CSIRO oceanographer Dr Gael Alory.
