A 520-million-year-old five-eyed fossil reveals arthropod origin

The discovery of Kylinxia, a shrimp-like fossil with five eyes, has provided crucial insights into the early evolution of arthropods. The study suggests that Kylinxia represents a transitional form between Anomalocaris and true arthropods, bridging the evolutionary gap between these two groups.

Argonne collaborates on largest COVID-19 viral sequence analysis in U.S.

Researchers analyzed over 5,085 strains of the virus, finding that a specific protein mutation became dominant during the second wave, causing increased transmissibility. The study also discovered a correlation between patients with this mutation and younger demographics, lower median incomes, and less severe symptoms.

Being in treatment with statins reduces COVID-19 mortality by 22% to 25%

A study published in the European Heart Journal found that patients on statin treatment had a lower risk of dying from COVID-19, with a 22-25% mortality reduction. Researchers analyzed data from 2,159 patients and concluded that fear of the pandemic should not lead to suspension of statin treatment.
