Science backs Cod Liver Oil as cure for arthritis

Scientists at Cardiff University (Wales, UK) have confirmed what thousands of people with arthritis have believed for years. Cod Liver Oil really is effective in treating joint pain and can slow, even reverse, the destruction of joint cartilage.

Cartilage is the ‘gristle’ that cushions bones and prevents them from grinding against each other. Loss of cartilage leads to osteoarthritis, the painful and disabling condition experienced by 1.5 million people in the UK and the major reason for joint replacement surgery.

Why we buy bad gifts for the ones we love most

Each holiday season, another woman who loves the rock band No Doubt will receive a plaid skirt that only the band's singer, Gwen Stefani, could pull off. Another athletic guy will receive an oversize sports jersey – even though off the field he prefers Brooks Brothers. Why are we so terrible at predicting the tastes of the ones we love? A new study explains why familiarity with another person actually makes predicting their tastes more difficult.

Evolutionary forces explain why women live longer than men

Despite research efforts to find modern factors that would explain the different life expectancies of men and women, the gap is actually ancient and universal, according to University of Michigan researchers.

"Women live longer in almost every country, and the sex difference in lifespan has been recognized since at least the mid-18th century," said Daniel J. Kruger, a research scientist in the U-M School of Public Health and the Institute for Social Research. "It isn't a recent trend; it originates from our deep evolutionary history."

Females, alcohol and hormones

Although women consume less alcohol than men, they are more susceptible to some of the negative medical consequences of alcohol use, such as cirrhosis of the liver, cardiac disease, and cognitive impairments. Animal studies have also shown that males and females differ on behavioral as well as electrophysiological measures of alcohol's effects. A study found that female rats are not only less sensitive to the sedating effects of alcohol, but that cycling hormonal levels can mediate alcohol's effects.

Break-up Of Antarctic Ice May Expose Marine Life To More Sunlight And Alter Food Chain

Despite the icy cold and darkness, beneath the frozen surface of the sea in Antarctica thrives a rich and complex array of plants and animals. But what will happen to all those creatures if global warming reduces the ice-cover, as is predicted for coming decades?

UNSW marine ecologists Dr Emma Johnston and Graeme Clark have been working with the Australian Antarctic Division to survey marine communities along the striking coast of Wilkes Land, east Antarctica.
