The percentage of middle and high school students who have tried electronic cigarettes more than doubled in a year, federal health officials reported Thursday.

The percentage of students in grades 6 through 12 who had ever used e-cigarettes increased from 3.3 percent in 2011 to 6.8 percent in 2012, the Centers for Disease Control and Prevention reported in Morbidity and Mortality Weekly Report. Those who reported currently using the devices increased from 1.1 percent to 2.1 percent.

Diverse Gut Microbes, A Trim Waistline And Health Go Together

The tale of the tape may be told, in part, by the microbes inside you.

Scientists have discovered new clues about how microbes in our digestive systems may affect health.

European researchers found that the less diverse those microbes are, the more likely people are to gain weight, become obese and develop risk factors for serious health problems.

Evidence has been mounting in recent years that bacteria and other organisms in our bodies do a lot more than just help us digest food.

Brains Of Dying Rats Yield Clues About Near-Death Experiences

Could the images common in accounts of near-death experiences be explained by a rush of electrical activity in the brain?

A burst of brain activity just after the heart stops may be the cause of so-called near-death experiences, scientists say.

The insight comes from research involving nine lab rats whose brains were analyzed as they were being euthanized. Researchers discovered what appears to be a momentary increase in electrical activity in the brain associated with consciousness.

Although the experiment relied on animals, the results could apply to humans, too, the researchers say.

Staying Healthy May Mean Learning To Love Our Microbiomes

Originally published on Thu September 5, 2013 4:07 pm

Not so long ago, most people thought that the only good microbe was a dead microbe.

But then scientists started to realize that even though some bugs can make us sick and even kill us, most don't.

In fact, in the past decade attitudes about the bacteria, fungi, viruses and other microbes living all over our bodies has almost completely turned around. Now scientists say that not only are those microbes often not harmful, we can't live without them.

Scientists Grow A Simple, Human Liver In A Petri Dish

"Liver buds" grow in petri dishes. The rudimentary organs are about 5 mm wide, or half the height of a classic Lego block.

Japanese scientists have cracked open a freaky new chapter in the sci-fi-meets-stem-cells era. A group in Yokohama reported it has grown a primitive liver in a petri dish using a person's skin cells.

The organ isn't complete. It's missing a few parts. And it will be years --maybe decades — before the technique reaches clinics.

Proposed Changes In Organ Donation Stir Debate

Hospitals and organ banks could get more leeway in decisions about donations.

The nation's organ transplant network will consider a controversial proposal Monday to overhaul the guidelines for an increasingly common form of organ donation.

The board of directors of the United Network for Organ Sharing will open a two-day meeting at the organization's headquarters in Richmond, Va., to consider new guidelines for donation after cardiac death.

Donation after cardiac death involves removing organs minutes after life-support has been stopped for patients who still have at least some brain activity.

Federal regulators are dropping plans to tightly control a procedure that is becoming increasingly popular for treating people stricken by life-threatening infections of the digestive system.

The Food and Drug Administration says the agency will exercise enforcement discretion and no longer require doctors to get the agency's approval before using "fecal microbiota for transplantation."

The case of a Pennsylvania girl who is dying from cystic fibrosis has sparked an emotional debate over how the nation allocates lungs for transplantation.

Ten-year-old Sarah Murnaghan is in intensive care at Children's Hospital of Philadelphia awaiting a lung transplant. Under the current rules, lungs from adults are offered to other adults and adolescents before being offered to children younger than 12.

Disinfect All ICU Patients To Reduce 'Superbug' Infections

To fight antibiotic-resistant staph germs like these, a study suggests disinfecting the skin of all intensive care patients.
Janice Carr CDC

Originally published on Thu May 30, 2013 3:41 pm

Hospitals can sharply reduce the spread of the drug-resistant bacteria in their intensive care units by decontaminating all patients rather than screening them and focusing only on those found to be infected already, researchers reported Wednesday.
