Hawaiian Ridge HOME to efforts to understand deep-ocean mixing
With waves - some 300 to 1,000 feet tall - traveling beneath the surface, internal tides at the Hawaiian Ridge and other such spots around the world may help scientists discover what causes 90 percent of the mixing in the world's ocean.

Are genetics the only reason for high blood pressure among certain hispanic populations?
A study of 700 Venezuelan men show that hypertension may not be caused by the factors historically blamed for the condition.

Questions have a higher pitch

New, independent research from the Economic & Social Research Council's 'Growing Older' Programme says that the odds of poor quality of life in old age increase by 50 - 70 per cent for people who live in rented housing compared to those who own their home.

Dartmouth researchers expose weakness of common parasite
Dartmouth Medical School geneticists in the Department of Microbiology and Immunology have discovered how to weaken a common human parasite to prevent disease in an animal model after infection by the normal parasite.

Corals are being robbed of light
It's not just overfishing and climate change causing coral death.

Predicting the species diversity of large herbivores in nature reserves
The number of species of large herbivores that can live in a nature reserve can be easily calculated using just rainfall and soil fertility data.

Science backs Cod Liver Oil as cure for arthritis
Scientists at Cardiff University have confirmed what thousands of people with arthritis have believed for years.

Modeling may show processes observation misses in volcanic eruptions
The Soufriere Hills volcano in Montserrat holds the key to improved modeling of vulcanian eruptions because it has been so well studied over the past seven years, according to a Penn State geologist in the current issue of Nature.

Satellite images help find safe routes to South Pole
Using satellite images and software, researchers at the Ohio State University are mapping land routes across the Antarctic that could make it safer and easier to transport equipment and supplies to the South Pole.

A current controversy: Is Europe about to freeze?
One of the odd possibilities that could emerge from global warming is that much of Europe, robbed of the ocean current patterns that help keep it warm, could rather abruptly enter a deep freeze and have a climate that more closely resembles Alaska than the modest temperatures it now enjoys.
