New research shows that enrolling 9th graders who are struggling academically in an ethnic studies course greatly improves the likelihood those students will graduate from high school and enroll in college.

Researchers create thin film polymer membranes capable of separating fluoride from chloride and other ions. Targeted ion selectivity by the filtering membranes could have important implications for water purification, environmental remediation and industrial production.

A genomic analysis of lung cancer in people with no history of smoking has found that a majority of these tumors arise from the accumulation of mutations caused by natural processes in the body. This study describes three molecular subtypes of lung cancer in people who have never smoked. These insights will help unlock the mystery of how lung cancer arises in people who have no history of smoking...

After examining the blood samples from nearly 200 COVID-19 patients, researchers have uncovered underlying metabolic changes that regulate how immune cells react to the disease. These changes are associated with disease severity and could be used to predict patient survival.

Could dying stars hold the secret to looking younger? New evidence suggests that white dwarfs could continue to burn hydrogen in the final stages of their lives, causing them to appear more youthful than they actually are. This discovery could have consequences for how astronomers measure the ages of star clusters.

Researchers found that a tool commonly used in research for evaluating a person's genetic risk for a disease, called a polygenic risk score, was no better at predicting the outcome of a schizophrenia patient's disease over time than written reports. The results raise important questions about the use of polygenic risk scores in real-world, clinical situations, and also suggest that a doctor's...

As their name suggests, ultradiffuse galaxies, or UDGs, are dwarf galaxies whose stars are spread out over a vast region, resulting in extremely low surface brightness, making them very difficult to detect. An international team of astronomers reports it has used sophisticated simulations to detect a few 'quenched' UDGs in low-density environments in the universe. A quenched galaxy is one that...

Over 200 health journals across the world have come together to simultaneously publish an editorial calling on world leaders to take emergency action to limit global temperature increases, halt the destruction of nature, and protect health.
