Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers
A new study investigating the respiratory system of insects may have solved a mystery that has intrigued physiologists for decades: why insects routinely stop breathing for minutes at a time. Challenging previous theories, researchers at UC Irvine and Humboldt University propose that insects such as grasshoppers, moths, butterflies, some types of fruit flies, beetles and bugs close off th...Falling ants glide back to trunk to avoid dangers of forest floor
An amazing variety of arboreal animals have learned to glide through the forest, from flying squirrels to flying lizards and frogs, and even ?frightening as it sounds ?snakes. Gliding ants ?the only wingless insects known to actively...Gladstone investigators discover how resting T cells avoid HIV infection
Scientists have discovered the mechanism that enables some CD4 T cells -- the main target of HIV -- to thwart the virus. The discovery, reported on April 13 in the online version of Nature, could open the door to an entirely new strategy for preventing the spread of HIV infection in the body's cells, according to the senior author of the study, Gladstone Institute of Virology and Immunology Direc...Travelers can avoid jet lag by resetting their body clocks
A simple, at-home treatment -- a single light box and the over-the-counter drug melatonin -- allows travelers to avoid jet lag by resetting their circadian body clock before crossing several time zones, according to new research being published in The Endocrine Society's Journal of Clinical Endocrinology and Metabolism. This treatment can also help those with delayed sleep phase syndrome (DSPS),...How plants avoid feeling the burn
Too much sun ?for plants as well as people ?can be harmful to long-term health. But to avoid the botanical equivalent of "lobster tans," plants have developed an intricate internal defense mechanism, called photoprotection, which acts like sunscreen to ward off the sun's harmful rays. "We knew that biomolecules called carotenoids participate in this process of photoprotection, but the ques...Spatial Behavior System, Avoidance from myNeuroLab.com

With e-mail dramatically increasing the sheer volume of electronic information stored and disseminated on a daily basis, your organization can ill-afford the consequences of not being prepared to deal with the evolving legal landscape of electronic discovery. As one jurist noted: "The corporate graveyard is littered with data preservation plans that were not properl...Efforts to avoid friendly fire spawned ancestor of todays RFID
British soldiers seeking ways to identify friendly aircraft in World War II were given a newly developed radar transponder system called IFF - Identification Friend or Foe. It was a crude system, but it was a way to tap into technology to identify something at a distance. Fast forward 65 years, and you'll find researchers working on today's version of remote identifi...Avoid sudden death by quick cooling
An emergency medicine expert said in New York on Thursday, at an American Medical Association press briefing on heart disease, that rapidly cooling people whose hearts have suddenly stopped, could provide a way to bring them back to life without organ damage. Dr. Lance B. Becker, Director of the Emergency Resuscitation Center at the University of Chicago said that thousands of people die...Avoid stress to have strong babies
Stress and anxiety during pregnancy could cause women to have smaller babies, researchers have discovered. They believe the effect is caused by reduced blood flow through the arteries that feed the uterus. Doctors from the Queen Charlotte's and Chelsea Hospital in London studied 200 expectant mothers. They found pregnant women who were more anxious or stressed had "significantly a...Change In Lifestyle Recommended To Avoid Cardiac Disease
India would have the maximum number of cardiac patients by 2020 if Indians do not resolve to change their lifestyle at the earliest. // The above warning has been issued by leading Cardiologists in the country. Stress, bad eating habits and the growing number of diabetic patients are contributing to the increasing incidence of heart ailments. About eight percent of India's population...Women on HRT should avoid alcohol
Many studies published in the recent past have argued about the implications of Hormone Replacement Therapy (HRT) on women who use them to manage menopausal symptoms. A new study, however, has gone further to show that women who are on HRT add to the risk of developing breast cancer// if they consumed alcoholic beverages. The study polled more than 44,000 women on their alcohol consump...
