Role of climate in end-Pleistocene extinctions

Climate change was a major factor in the extinction of 38 genera of large mammals in North America at the end-Pleistocene glacial-interglacial transition. The species' histories and adaptive tolerances were critical in their survival during earlier transitions, but not at the last transition when humans arrived.

How genetic codons may have evolved

A study analyzed 4,225 protein-coding genes in the Escherichia coli genome to understand the evolution of genetic codons. The researchers discovered a disproportionate use of specific serine codons, suggesting their independent emergence during evolution.

COVID-19 triggers OCD in children and young people

A study by Aarhus University finds that COVID-19 exacerbates obsessive thoughts and compulsions in children and young people with OCD. The condition often worsens due to anxiety about illness or loss, particularly among younger children who are more dependent on others.
