biogenic

The fact that the components on the asteroid is racemic meant or heavily suggested that they were formed using non-biogenic means.

Molecular clocks could indicate a biogenic origin, but as yet there's no way to demonstrate what variety of biogenic origin.

According to the agency, natural gas drilling does not lead to the presence of biogenic methane.

Storage vaults for biogenic carbon is likely the most energy and cost efficient way to sequester carbon at this time.

These accumulations exist in several stratigraphic intervals throughout Svalbard and show both thermogenic and biogenic origins.

Subsurface storage vaults for biogenic carbon is likely the most energy and cost efficient way to sequester carbon at this time.

Rather it is part of the natural cycling of carbon through the biogenic carbon cycle.

If there are only extremely small amounts of materials of biogenic origin Curiosity is unlikely to be able to definitively identify them.

Now, there could be a non-biogenic source for these, but when you find something like this it points to an active planet.

Which meant that every nuance of the terrain encoded a 4.5-billion-year simulated history of plate tectonics, atmospheric chemistry, biogenic effects, and erosion.

Keep in mind that biogenic reefs have formed over thousands and thousands of years.

It's specially designed to transmit biogenic energy on a chromoelectric wavelength and send uplifting and entertaining messages to the nuclei of every cell.

Where virus was squarely in the heritable characteristics under selection pressure ("life") bucket, rather than abiotic or biogenic.

Here on Earth, silica in the ocean is scrubbed out by microorganisms that create silica shells; these tiny shells fall out into sediments, where (in deep ocean) they eventually form a kind of biogenic rock called "chert".

I read about the Biogenic Carbon Cycle on the UC Davis website: " As a by-product of consuming cellulose, cattle belch out methane, there-by returning that carbon sequestered by plants back into the atmosphere.

"Periods of lead exposure during the childhoods of these two French Neanderthals are remarkable, as biogenic lead bands were not apparent in the ~100-ka-old Belgian individual discussed above, and decades of research have shown that there is no safe level for lead in humans and other animals."
