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.

Gut Bacteria We Pick Up As Kids Stick With Us For Decades

Streptococcus bacteria, like this strain, can be found in our guts.

Most of the microbes in our guts appear to remain stable for years, perhaps even most of our lives, researchers reported Thursday.

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.
