Secrets of the Longest-Living Mammal Revealed


Secrets of the Longest-Living Mammal Revealed

The genome of the bowhead whale was released this week by scientists who say that it may hold the key to longer and healthier lives for humans. The bowhead whale is the largest animal whose genome has been sequenced. It lives longer than any other mammal, with a lifespan of up to 200 years. Scientists studying its genome found significant differences in genes related to cell cycle, DNA repair, and aging process compared to other mammals. Although it has about 1,000 times as many cells as a human, its cells have a far more efficient anti-tumor response. More… Discuss

Why Some Get SAD


Why Some Get SAD

Seasonal affective disorder, or SAD, is a form of depression most often experienced in winter, when exposure to sunlight is limited. Although the mechanism of the disorder is not entirely understood, researchers are closing in on its causes. Data show that people with SAD have higher evening and nighttime levels of serotonin transporter (SERT) protein during the winter months than do healthy volunteers. SERT carries serotonin, a neurotransmitter that helps regulate mood, back into nerve cells where it is not active, so these higher SERT levels could conceivably account for the “winter blues.” More… Discuss

“Nagged to Death” Not Just a Figure of Speech


“Nagged to Death” Not Just a Figure of Speech

Frequent arguments with your partner, children, friends, or other relatives could be taking years off your life. Research shows an association between stressful social relations and increased mortality risk. Men appear to be more vulnerable to the effects of this sort of stress than women. The effects are also stronger in those who are unemployed. The findings are not all that surprising given that stress is known to have physiological effects that increase the risk of cardiovascular disease, but they may cause us to think twice the next time we find ourselves on the verge of nagging a loved one over some minor matter.

NEWS: LIFESTYLE CHANGES COULD CUT MISCARRIAGE RISK


Lifestyle Changes Could Cut Miscarriage Risk

Researchers say that more than a quarter of first-timemiscarriages are preventable and could be avoided if women made certain lifestyle changes. Heavy lifting,obesity, being underweight, alcohol consumption, and working night shifts during pregnancy were all found to be factors that elevate miscarriage risk. Age was also found to be a factor, with women in their mid-30s and above more likely to lose a pregnancy. It is important not only for individual women to be aware of these risks but also for policymakers and employers to know of them and help pregnant women avoid them whenever possible. More… Discuss
