Although dinosaur eggs have now been found on every continent, it’s not always clear which species laid them. Researchers have narrowed down the list for an unknown eggshell from Mexico by comparing its microstructure and composition with four known samples.

Researchers have used a combination of laboratory experiments and computer modeling to reveal that PFASs can interact with the estrogen receptor in different ways to influence estrogen-controlled gene expression.

A new study suggests that COVID-19 affects the human body’s blood concentration levels of specific metabolites. Three metabolites identified in the study could act as biomarkers and hold potential to be measured through an inexpensive blood test to quickly screen patients for the disease.

Frozen methane deposits in the Arctic Ocean, a key carbon store, risk release into the atmosphere as permafrost thaws in our warming climate. This could contribute to ongoing greenhouse gas problems.
