Researchers from Woods Hole, Scripps oceanographic institutes sail on new Coast Guard ice breaker to study climate, ocean changes

A University of Massachusetts Amherst geoscientist is part of a team of researchers sailing the Bering and Chukchi seas this summer, searching for clues about the sea floor history and the land bridge that once existed between what is now Alaska and Russia. The team will also explore how the disappearance of the land bridge may have affected that region&#14

Russian scientists have found one more cause of depletion of the ozone layer. They think that abyssal gases can go to the surface and reach stratosphere, deteriorating the ozone shield. Underground nuclear explosions enforce this process. A geologist Boris Golubov of the Institute of Geosphere Dynamics RAS and a climatologist Grigoriy Kruchenitsky of Central Aerology Observatory are authors of this hypothesis.

Winter and spring are the most common seasons for ozone holes above Yakuti

Nearly one in ten adults suffers from migraine
UK male sufferers alone lose 4m working days with an estimated productivity loss of £750m
Migraine accounts for more than half of all headaches New collaborative research by City University, the University of Essex and the Institute of Optometry, London shows that coloured filters are effective in reducing migraine symptoms for some sufferers.

Very light smokers significantly increase their risk of a heart attack, shows research in the Journal of Epidemiology and Community Health. Furthermore, women are much more susceptible than men to the detrimental effects of tobacco, even if they don’t inhale.

The findings are based on a population sample of over 12,000 men and women taking part in the Copenhagen City Heart Study, which began in 1976.

The participants, all aged 20 or older at the start of the study, were monitored up

The thigh length of babies in the womb is as strong an indicator of subsequent childhood – and potentially adult – blood pressure as birthweight, suggests a study in the Journal of Epidemiology and Community Health.

Researchers scanned 707 developing fetuses to measure the dimensions of their abdomen and head circumferences and the length of the thigh bones (femurs). The growing babies were scanned five times each between 18 and 38 weeks of pregnancy. Blood pressure was then measured in 300

Looking into the interior of the Earth or the Sun is a bit similar to examining a baby in its mother`s womb using an ultrasound scan. Light cannot penetrate the area, so we make pictures in these cases using sound waves, which human ears cannot hear. With SOHO, ESA has probed deeply into the Sun using the sound-waves principle, and with great success. The future missions, Solar Orbiter and Eddington, will look inside our Sun and other stars, respectively, in a similar way.

Here on Earth, whe
