NILES — United States Gypsum Corp. announced the permanent closure of its Phillips Manufacturing plant in Niles. The company cited financial challenges and shifting market conditions in a news ...

Sellam and his colleagues tested LIMS and an optical microscope on Algerian gypsum and found filament-like structures—previously identified as bacteria—within dolomite, clay minerals and pyrite.

Once Sellam got the samples to the lab, he saw sinuous filaments preserved in the mineral. These were ancient, fossilized microbes, "which is an indication that gypsum could preserve life," says ...

In the research article’s conclusion, Sellam notes that the team’s findings “strongly support the biogenicity of the fossil filament in gypsum.” Still, the Star Trek-style ability to distinguish true ...

“While our findings strongly support the biogenicity of the fossil filament in gypsum, distinguishing true biosignatures from abiotic mineral formations remains a challenge,” said Sellam. He noted ...

This event left behind mineral deposits similar to those ... twisting fossil filaments embedded in the gypsum. These filaments were surrounded by dolomite, clay, and pyrite - minerals known ...

Gypsum deposits formed on Mars could conceal evidence of past life on the planet — microbes similar to the first life that formed on Earth ... “While our findings strongly support the biogenicity of ...

thanks to a new study of Earthly microbial fossils embedded in the mineral gypsum that was produced when the Mediterranean Ocean dried up over 5 million years ago. Mars was once wet, with rivers ...

"While our findings strongly support the biogenicity of the fossil filament in gypsum, distinguishing true biosignatures from abiotic mineral formations remains a challenge," cautioned Sellam.

The abundance of elements related to gypsum (O, S, Ca) and the fossil filament were analyzed in detail for the 425 positions . The gypsum element intensities are uniformly distributed across the ...
