COVID-19 drugs persist in wastewater, may pose risk to aquatic organisms

Treated wastewater efluent is sprayed at Penn State’s beneficial reuse site, the “Living Filter.” This diverts the wastewater from Spring Creek and allows the soil to act as a natural filter for any chemical residuals that remain in the wastewater.

Researchers find spaceflight may be associated with DNA mutations, increased risk of heart disease and cancer

a) We identified somatic mutations in known clonal hematopoiesis of indeterminate potential (CHIP) driver genes using peripheral blood mononuclear cells isolated from 14 astronauts who flew short space Shuttle missions lasting a median of 12 days between 1998–2001. Created with b) Number of somatic nonsynonymous single nucleotide variants (SNVs) in CHIP-driver genes harbored per … Read more

Risk of catastrophic California ‘megaflood’ has doubled due to global warming, researchers say

Credit: Unsplash/CC0 Public Domain Even today, as California struggles with severe drought, global warming has doubled the likelihood that weather conditions will unleash a deluge as devastating as the Great Flood of 1862, according to a UCLA study released Friday. In that inundation 160 years ago, 30 consecutive days of rain triggered monster flooding that … Read more
