Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

The first life here on Earth appeared about 4 billion years ago.

In one place these pioneering organisms may have emerged is at hydrothermal vents, deep underwater,

where unusual chemistry provided energy for primitive life forms to survive.

Life forms like the methane belching

microbes found at the vents today. Now, for the first time, researchers have found evidence of

methane producing life in similarly extreme conditions, but up here at the surface of the earth,

at a spring in northern California called the Cedars. The water there is extremely basic, with a pH of 11.6, and it contains no oxygen, not an easy place to survive.

Researchers tested water and sediment there at the Cedars.

Some samples got dosed with mercuric chloride to kill any life present.

Those dose samples produce no methane.

But the samples in which microbes were allowed to survive did put out methane, confirming that at least

some of the methane at the springs is indeed biological in origin. The findings appear in the

Journal of Geophysical Research, Biogeosciences. The finding has implications for climate change alleviation

because a geologically similar spring in Oman has been proposed as a site for carbon storage,

pumping CO2 underground where it gets incorporated into stone. But the extremophiles at the cedars

can use that CO2 to make methane, an even more potent greenhouse gas.
