Scientists tap into Antarctic octopus venom
Researchers have collected venom from octopuses in Antarctica for the first time, significantly advancing our understanding of the properties of venom as a potential resource for drug-development.

Unaccounted feedbacks from climate-induced ecosystem changes may increase future climate warming
In addition to the carbon cycle-climate interactions that have been a major focus of modeling work in recent years, other biogeochemistry feedbacks could be at least equally important for future climate change.

Scientists test Moreton Bay as coral 'lifeboat'
An international team of scientists has been exploring Moreton Bay, close to Brisbane, as a possible 'lifeboat' to save corals from the Great Barrier Reef at risk of extermination under climate change.

Non-human sugar in biotech drugs causes inflammation
Researchers at the University of California -- San Diego School of Medicine have discovered that a kind of sugar molecule common to chimpanzees, gorillas and other mammals but not found in humans provokes a strong immune response in some people, likely worsening conditions in which chronic inflammation is a major issue.

Researchers discover how key enzyme repairs sun-damaged DNA
Researchers have long known that humans lack a key enzyme -- one possessed by most of the animal kingdom and even plants -- that reverses severe sun damage.

Study establishes most effective technique for diagnosing childhood tuberculosis in resource-poor countries
A tuberculosis culture method called microscopic-observation drug-susceptibility, using two gastric aspirate specimens from each child tested, is significantly more sensitive and faster than conventional culture tests, diagnosing 70 percent more cases of pulmonary TB among children ages 12 years and under.

Now that's what I call a rat
Archaeological research in East Timor has unearthed the bones of the biggest rat that ever lived, with a body weight around 6 kg.

Rare and common genetic variations responsible for high triglyceride levels in blood

Why more education lowers dementia risk
A team of researchers from the UK and Finland has discovered why people who stay in education longer have a lower risk of developing dementia -- a question that has puzzled scientists for the past decade.
