Black patients diagnosed with aggressive leukemia experience worse outcomes, but differences not linked to key genetic changes

A new study by University of Maryland researchers found that Black patients with aggressive leukemia have lower survival rates and are more likely to die from the disease compared to white patients. The disparity is attributed to younger age at diagnosis rather than genetic differences, according to Dr. Shella Saint Fleur-Lominy.

Holding back laughter

A research team at the University of Göttingen investigated how laughter can be regulated and found that social cues can strongly interfere with these efforts. The results showed that suppression and distraction were effective strategies to hold back laughter, while cognitive reappraisal could reduce how funny the jokes felt.
