Women less touchy about status than men

Men who slide down the social ladder are four times more likely to experience depression than those who improve their social status, whereas thereís no marked difference in mental health between women who have moved up or down the social ladder, according to a study done by researchers at the University of Newcastle upon Tyne. They used the occupation of the head of the household as the marker for social status, and surveyed men and women born in 1947 in Newcastle from childhood to age 50. The findings can be explained by the fact that men born in this era gained much of their self-esteem from their careers, whereas women found fulfilment from social pursuits outside work, such as children and friendships. Itís also possible that women are more emotionally resilient in this type of situation, say the researchers.

Stroke invites epileptic fits

The results of a Norwegian study indicate that stroke patients are at an increased risk for developing epileptic seizures. Doctors need to be aware of the risk since anti-epileptic drugs may be effective in preventing seizures, Dr Morten I. Lossius told Reuters. Lossius, of the National Center for Epilepsy, conducted a long-term study of 484 patients who had an ischemic stroke which result from an interruption of blood flow to the brain. Experts found that 12 patients developed epilepsy within a year of the stroke and 15 developed post-stroke epilepsy within eight years of the event. Post-stroke epilepsy was defined as having two or more seizures after stroke.

Pocket-size portable kidney

Using nanotechnology, researchers have taken the first step toward developing a fully functioning artificial kidney for patients with end-stage renal disease, possibly eliminating the need for dialysis or kidney transplantation. The device is small ' about the size of a paperback book ' and therefore portable or implantable. In the journal Hemodialysis International, researchers from the University of California at Los Angeles note that the equipment consists of two membranes operating within one cartridge. They mimic filter structures found in a real kidney. The researchers found that the device, operating 12 hours a day, seven days per week, provided a greater filtering rate than conventional dialysis given three times a week.

Psychopaths as stock traders

A team of neurologists have concluded that psychopaths can become the best financial traders. Because the emotionally impaired (such as psychopaths) are more willing to gamble for high stakes than normal individuals, scientists at the University of Iowa think that they fit the bill of stock traders.
