MIT scientists find a way to rejuvenate the immune system as we age
As the immune system weakens with age, scientists have found a way to restore some of its lost strength. By delivering mRNA to the liver, they created a temporary source of immune-boosting signals that normally come from the thymus. Older mice treated this way produced more

Genetic study reveals two killer whale ecotypes near Hokkaido waters
The species Orcinus orca, generally known as orcas or killer whales, is made up of many genetically distinct populations called ecotypes. Each ecotype indicates an ecological specialization with its own ecological and phylogenetic characteristics.
How young adult literature and philosophy can help provide better role models for masculinity
Toxic masculinity doesn't stop at marginalizing women and LGBTQ+ people. It harms straight men by discouraging emotional expression, tenderness, and connection.
