New research finds unprecedented weakening of Asian summer monsoon

New research using tree ring records reveals a 80-year decline in Asian summer monsoon rainfall, resulting in regional droughts and hardships. The study attributes the decline to man-made atmospheric pollutants, specifically sulfate aerosols, which coincide with industrial development and emissions in China.

Genomic collision may explain why many kidney transplants fail

A genomic collision may explain why many kidney transplants fail due to genetic incompatibility between donor and recipient. The study found that recipients with two copies of a deletion near the LIMS1 gene had a significantly higher risk of rejection when the donor kidney had at least one full-sized version of the same gene.
