Health News:How can we prevent suicide? ♦ How magnetic pulses change the brain ♦ Prolonged television watchers- higher risk of fatal pulmonary embolism

Scientists show how magnetic pulses change the brain in treatment for depressed patients A group of scientists have found a way of understanding how transcranial magnetic stimulation (TMS) can give relief to severely depressed patients. TMS is used as an alternative to electroconvulsive therapy, but it is not known how it achieves its therapeutic effect. Understanding how it works may open the door to better, more targeted treatment for depression and other conditions.
How can we prevent suicide? Major study shows risk factors associated with depression A major multi-national study of suicides has identified the behavior patterns which precede many suicide attempts. This may lead to changes in clinical practice in the care of patients affected with depression, as it shows the clinical factors which confer major risk of suicide attempts.
Prolonged television watchers have higher risk of fatal pulmonary embolism Prolonged television watchers have a higher risk of fatal pulmonary embolism, a condition associated with long haul flights.
Imitating viruses to deliver drugs to cells Viruses are able to redirect the functioning of cells in order to infect them. Inspired by their mode of action, scientists have designed a "chemical virus" that can cross the double lipid layer that surrounds cells, and then disintegrate in the intracellular medium in order to release active compounds. To achieve this, the team used two polymers they had designed, which notably can self-assemble or dissociate, depending on the conditions.
Short sleepers are four times more likely to catch a cold A new study led by a sleep researcher supports what parents have been saying for centuries: to avoid getting sick, be sure to get enough sleep.
