It all starts with the egg.

In spring, chickens start laying again, bringing a welcome source of protein at winter's end. So it's no surprise that cultures around the world celebrate spring by honoring the egg.

Some traditions are simple, like the red eggs that get baked into Greek Easter breads. Others elevate the egg into an elaborate art, like the heavily jewel-encrusted Faberge eggs that were favored by the Russian czars starting in the 19th century.

Last week, the Centers for Disease Control and Prevention told doctors they should really, really think twice before prescribing opioids for chronic pain.

And now the doctors are telling us that meditation and cognitive behavioral therapy often work better than pain meds and other medical treatments for chronic back pain.

Psychologists disagree on whether expecting your marriage to be a deeply fulfilling relationship makes it more likely that the union will thrive, or that it will doom you to disappointment.

So, psychologists, should we just go ahead and expect the worst after the honeymoon?

Eric O'Grey knew he was in trouble. His weight had ballooned to 320 pounds, and he was spending more than $1,000 a month on medications for high blood pressure, Type 2 diabetes and high cholesterol.

In 2010, a physician told him to buy a funeral plot, because he would need it in five years. He was 51 years old.

We all know ancestors give us our hair color, but the roots of gray hair have been less clear. Is it genetics, or stress?

Marie Antoinette supposedly went completely white the night before they lopped off her head. And our presidents seem to go gray much faster than those of us with less weighty roles.

It turns out you can blame Mom and Dad, at least a bit. Scientists say they've identified the first gene for gray hair.

The earlier a child with autism can be identified and get treatment the better, child development specialists say. So there's been a push to have pediatricians give all toddlers screening tests for autism during well child visits.

But the influential U.S. Preventive Services Task Force said Tuesday that there's not yet enough evidence to show that screening all children delivers measurable benefits, a decision sure to frustrate or anger many in the autism community.

The odds of getting Alzheimer's disease or other forms of dementia are declining for people who are more educated and avoiding heart disease, a study finds. The results suggest that people may have some control over their risk of dementia as they age.

This isn't the first study to find that the incidence of dementia is waning, but it may be the best so far. Researchers looked at 30 years of records from more than 5,000 people in the famed Framingham Heart Study, which has closely tracked the health of volunteers in Framingham, Mass.

If you fall off a curb, bop your head and go to the ER to make sure you're OK, there's a good chance you'll be trundled off for a CT scan.

That might sound comforting, but people with injuries minor enough that they get sent home are increasingly being given computed tomography scans, a study finds. That's despite efforts to reduce the unnecessary use of CTs, which use radiation and increase the lifetime risk of cancer.

Smoking is the #1 cause of premature death and preventable illness in the United States. And since one-third of Medicaid participants smoke, compared to 17 percent of the general population, you'd think the states would be all about helping people in their Medicaid programs to quit.

But just 10 percent of Medicaid participants who smoke are getting medication to help them quit, according to a study published Tuesday in the journal Health Affairs. That's 830,000 people in 2013.

Although many people know someone who has abused prescription opioids, people still think of opioid abuse as a criminal justice issue more than a health problem, a study finds.

Illegal drug dealing is mentioned most frequently in news stories as the cause of prescription painkiller abuse, and two-thirds of abusers are shown as being actively involved in crimes, according to an analysis by researchers at Johns Hopkins Bloomberg School of Public Health.
