Scientists have found one more reason that pregnancy and obesity can be a bad combination.

A new study in the journal Pediatrics suggests that moms who are obese or have diabetes are more likely to have a child with autism or another developmental problem.

The finding is "worrisome in light of this rather striking epidemic of obesity" in the U.S., says Irva Hertz-Picciotto from the MIND Institute at the University of California, Davis, one of the study's authors.

UPDATE 4:23 p.m.

The U.S. Food and Drug Administration has denied a call to ban the plastic additive BPA from food packaging. The action comes after government scientists found little reason to think people are being harmed by the chemical.

The FDA was responding to a petition from the Natural Resources Defense Council, which called for the ban on BPA, also known as bisphenol A, from any use where it comes in contact with food.

How Your Brain Is Like Manhattan

This image shows the grid structure of the major pathways of the brain. It was created using a scanner that's part of the Human Connectome Project, a five-year effort which is studying and mapping the human brain.

It turns out your brain is organized even if you're not.

At least that's the conclusion of a study in Science that looked at the network of fibers that carry signals from one part of the brain to another.

New Methods Could Speed Up Repair Of Injured Nerves

When a nerve is injured, it's often hard to get it to regrow fast enough to restore function.

But now researchers say they can speed up that process, so that damaged nerves can be healed in days instead of months — at least in rats.

The scientists say they've developed a technique that reconnects the severed ends of a nerve, allowing it to begin carrying messages again very quickly. Usually, severed nerves must regrow from the point of injury — a process that can take months, if it ever happens.

Addicts' Brains May Be Wired At Birth For Less Self-Control

Many addicts inherit a brain that has trouble just saying no to drugs.

A study in Science finds that cocaine addicts have abnormalities in areas of the brain involved in self-control. And these abnormalities appear to predate any drug abuse.

The study, done by a team at the University of Cambridge in the U.K., looked at 50 pairs of siblings. One member of each pair was a cocaine addict. The other had no history of drug abuse.

'I Wanted To Live': New Depression Drugs Offer Hope For Toughest Cases

Chris Stephens, 28, who has been battling depression all of his life, plays with his dogs at home in Concord, Calif., on Friday. After a dose of ketamine, Stephens says, "I actually wanted to do things. I wanted to live life."

A club drug called "Special K" is generating a lot of buzz among researchers who study depression.

That's because "Special K," which is actually an FDA-approved anesthetic named ketamine, can relieve even suicidal depression in a matter of hours. And it works on many patients who haven't responded to current antidepressants like Prozac.

Those traditional drugs, which act on the brain's serotonin system, can take more than a month to kick in, and don't work for up to 40 percent of people with major depression.

Could A Club Drug Offer 'Almost Immediate' Relief From Depression?

Ketamine has been used as an anesthetic for decades. It's also a widely popular but illegal club drug known as "Special K." When administered in low doses, patients report a rapid reduction in depression symptoms.

There's no quick fix for severe depression.

Although antidepressants like Prozac have been around since the 1970s, they usually take weeks to make a difference. And for up to 40 percent of patients, they simply don't work.

As a result, there are limited options when patients show up in an emergency room with suicidal depression.

The doctors and nurses at Ben Taub General Hospital in Houston say they see this problem every day.

Common Chemicals Could Make Kids' Vaccines Less Effective

The more exposure children have to chemicals called perfluorinated compounds, the less likely they are to have a good immune response to vaccinations, a study just published in JAMA, the Journal of the American Medical Association shows.

The finding suggests, but doesn't prove, that these chemicals can affect the immune system enough to make some children more vulnerable to infectious diseases.
