Women who hold back feelings of anger may end up more irate in the long run. According to new research, women experience a rebound effect when they suppress angry emotions, which can result in greater feelings of fury.

In the study, Judith Hosie and Alan Milne of the University of Aberdeen compared different methods of regulating anger and sadness in subjects exposed to footage from emotional films. The researchers instructed one group of men and women to express any feelings of anger brou

Scientists have manufactured a microscale bicycle chain comprised of silicon links thinner than a human hair that behaves just like its regular-sized counterpart. The tiny chain system could one day help power microscopic devices.

Ed Vernon, a technologist at Sandia National Laboratories, designed and patented the 50-link silicon microchain (see image), which was built by the lab’s Microelectronics Development Laboratory (MDL). The centers of the tiny links are separated by just 50 mic

Radiologists in Nottingham have discovered a fast and accurate technique to diagnose deep vein thrombosis (DVT), which may be particularly helpful to pregnant women and travellers at risk of developing dangerous blood clots.

In a study funded by the British Heart Foundation and published this week in the American journal, the Annals of Internal Medicine, (15 January 2002, volume 136, number 2) Professor Alan Moody and his team in the department of academic radiology at the University of Nott

Missing protein leaves mice impervious to pain

Researchers have a new lead for treating pain. A protein called DREAM appears to play a key role in how mice respond to heat, touch and inflammation 1 .

Mice lacking DREAM seem oblivious to all types of pain, find Josef Penninger and his colleagues at The AMGEN Institute, Toronto, Canada. The animals can bear acute pain – the kind caused for example by heat, pressure, or injections as well as chronic inflammatory

Belt tightening cloud could have silver-lining for Europe’s planet hunters

European planet hunters are rallying round a beleaguered effort to launch the first spacecraft that might detect Earth-like planets beyond our own Solar System. Meeting in London last week they agreed that the low-cost, low-risk mission has a lot to offer.

The planet-spotting mission Eddington has been approved by the European Space Agency (ESA), but is currently on hold awaiting funds; unless they ma

Shared names prompt good deeds.

When seeking help from a stranger, ask someone who shares your name: people are more likely to assist a namesake, an e-mail study has revealed 1 .

A shared name indicates two people are likely to share genes, so evolution may have taught us to be nice to our namesakes, suggests psychologist Margo Wilson who carried out the study at McMaster University in Hamilton, Ontario, Canada.

Unusual names are particularly good a
