If you don't believe in horoscopes, you're in step with science. But that's not the same as saying the season of your birth cannot affect your fate. Hundreds of studies, published in peer-reviewed journals, have suggested that the month a person is born in is associated with characteristics such as temperament, longevity and susceptibility to certain diseases. Scientists say that even though some of these findings are probably spurious - if you dig around in data, you will eventually find correlations just by chance - other effects are very likely real, triggered not by the alignment of the planets but by exposures during prenatal and early postnatal lives.

The human circadian rhythm, a tyrant that dominates human existence, may be reset far more easily than previously believed, according to a new study in today's issue of Science magazine.

The links between sleep and cancer are now so many, you could build a chain. A new study has found that for men who suffer insomnia and unwelcome wakefulness, the risk of prostate cancer is greater than for those whose sleep is undisrupted. That research expands on a growing body of evidence that men and women whose sleep is short, broken or of poor quality are at higher risk of developing a wide range of cancers. Research has long linked overnight shift work -- and the circadian rhythm disruptions that are common with it -- as a risk factor for breast cancer and endometrial cancers in women.

TV sets, laptops, iPads and iPhones are modern society's instruments for increased productivity, social connectedness and entertainment after a long day's work. Ironically, a new study published in Molecular Psychiatry shows that these devices also contribute to an increase of major depressive disorder. The 24-hour society made possible by the advent of the electric light bulb has come at a significant biological cost. Light at night disrupts the body's natural circadian rhythms and has been linked to breast cancer, heart disease and obesity.

When the occasional night spent walking the floor with a crying baby or rocking a toddler becomes a common occurrence, pediatricians often advise a little pharmaceutical help. A survey of 671 mostly suburban pediatricians showed that 75% had recommended sleeping medication for a child within the last six months. But few studies have examined the effectiveness of sleeping medicines in children, and no medication has been approved for them by the Food and Drug Administration.

For some people who suffer from insomnia, traditional treatments such as behavior therapy and prescription drugs produce undesirable side effects or don't work. This makes folk remedies and alternative health treatments for insomnia very popular. But do they work? Here is what some experts say: Warm milk: Milk contains the amino acid tryptophan, which is touted to alleviate stress and produce serotonin, a brain chemical that helps control sleep.

As summer winds down, another new school year brings fresh notebooks, sharp pencils and — for many kids — a new cycle of sleep deprivation. With classes that start as early as 7 a.m. and buses that pull up long before sunrise, some 80% of American kids in grades 6 through 12 are falling short of sleep recommendations during the school year, according to research by the National Sleep Foundation, a sleep advocacy group. Overtired kids, studies suggest, struggle with depression.
