Neuroscientists have mapped the brain structures that affect general intelligence. The study adds new insight to a highly controversial question: what is intelligence, and how can we measure it?

The seasonal increase of influenza has long baffled scientists, but a new study has found that seasonal changes of absolute humidity are the apparent underlying cause of these wintertime peaks. The study also found that the onset of outbreaks might be encouraged by anomalously dry weather conditions, at least in temperate regions.

Unless action is stepped up to properly collect and recycle materials, many developing countries face the specter of fast-rising hazardous e-waste mountains this coming decade with serious consequences for the environment and public health, according to experts.

Researchers investigating UK samples have found no association between the controversial xenotropic murine leukemia virus-related virus and chronic fatigue syndrome. Their study calls into question a potential link described late last year by an American research team.

Biogas from refuse produces 95 per cent less greenhouse gas emissions than gasoline, according to a new research report. With a few simple improvements to the biogas plants, the figure can rise to 120 per cent — i.e. biogas becomes more than climate neutral. This can be compared with the standard figures used today, which [...]

While the otherworldly behavior of teenagers is well documented, researchers have taken a significant step toward finally unraveling the actual brain activity that can drive adolescents to engage in impulsive, self-indulgent, or self-destructive behavior.

How do you study — and try to cure in the laboratory — an infection that only humans can get? A team of researchers does it by generating a mouse with an almost completely human liver. This “humanized” mouse is susceptible to human liver infections and responds to human drug treatments, providing a new way [...]

A new study suggests that the bacteria that cause typhoid fever collect in tiny but persistent communities on gallstones, making the infection particularly hard to fight in so-called “carriers” — people who have the disease but show no symptoms. Humans who harbor these bacterial communities in their gallbladders, even without symptoms, are able to infect [...]

In 2007, the Arctic lost a massive amount of thick, multiyear sea ice, contributing to that year’s record-low extent of Arctic sea ice. A new NASA-led study has found that the record loss that year was due in part to the absence of “ice arches,” naturally-forming, curved ice structures that span the openings between two [...]

Scientists have discovered the disease, known medically as leptospirosis, was traditionally a concern for males working in the agricultural and livestock industries, as it is contracted from contact with the urine of host animals.
