Women seven times more likely than men to admit sexually acquired infection

Women are seven times more likely than men to admit to a partner that they have a sexually acquired infection, reveals research in Sexually Transmitted Infections. The findings were irrespective of age or type of infection.

The findings are based on three population surveys of sexual behaviour carried out in France in the early to mid 1990s. Two of the surveys comprised a total of around 7000 adults; the third dealt with just over 6000 adolescents from 15 upwards. All those surveyed were ask

Breakthrough for nano threads

Europe is one step ahead of the US in the development of a new type of semiconductor structure consisting of incredibly thin nano threads. A Swedish team headed by Professor Lars Samuelson at the LTH, the Lund Institute of Technology, Lund University, has taken the lead in this field of research. “In nano threads, we can combine semiconductor materials that no one has previously been able to grow. This results in entirely new electrical properties: a single electron can be monitored and made to run a

Insulin Pills

The issue of insulin-dependent diabetes has long been discussed. No wonder, as the problem concerns more than 5% of the world population. However, despite the enormous efforts and funds spent on its solution, the scientists so far have failed to replace the injections with pills. The difficulty is that insulin (like any other polypeptide) gets easily destroyed under the influence of proteolytic enzymes in the stomach and small intestines. The scientists have tried a variety of means: insulin plasters

COLD safer than HOT

New theory shows that high performance needn’t mean high risk.

For man-made systems such as machines and markets, catastrophe lurks somewhere between high risk and high performance. US physicists may have found a way to strike the optimal balance 1 .

This trade-off is familiar to the financial world. Brokers develop investment portfolios to provide the best returns within a specified level of risk. Mark Newman and co-workers at the Santa Fe Institute in New M

World’s Largest Switchboard for Climate Monitoring

Europe’s showpiece in climate monitoring is called Envisat. Fully equipped, the largest, most complex, and most powerful Earth observation satellite of the European Space Agency (ESA) is 25 meters high, ten meters wide and weighs over eight tons, scheduled for launch in the night of 28 February /1st March on an Ariane 5 launcher.

Europe’s flying behemoth is on the trail of climate change. It will deliver data about global warming, ozone depletion and climate change for at least five

South Pole re-routed

Satellites see through snow to steer safely across Antarctica.

Satellite images that expose perilous crevasses now reveal safe overland routes to the South Pole. Carolyn Merry of Ohio State University in Columbus has pieced together high-resolution satellite pictures that see through the snow, to map the passable Pole 1 .

Since a snow tractor, floundered into a hidden fissure in 1991, all supplies have been flown into the US South Pole research station. Safe t
