Possible New Human Species Found through 300,000-Year-Old Jawbone Fossil

The discovery has enabled a more detailed analysis of where the Hualongdong people fit on the human family tree. The mandible has a mixture of both modern and archaic features. For example, the bone along the jawline is thick, a feature shared with early human species, such as Homo erectus. It also lacks a true chin, the presence of which is a key feature of Homo sapiens.

Researchers find high concentrations of microplastics in cave water and sediment

In two recent papers, Saint Louis University researchers report finding high concentrations of microplastics present in a Missouri cave system that had been closed to human visitors for 30 years.

Elizabeth Hasenmueller, Ph.D., associate professor of Earth and Atmospheric Sciences and associate director of the WATER Institute at SLU, and her team published findings in the journals, Science of the Total Environment and Water Research, finding significant levels in Cliff Cave in Saint Louis County, Missouri.

The research, which originated from Hasenmueller’s research group and Karst Hydrology class, allowed students on the team to participate in and publish their findings.
