Science News: Major Breakthroughs in Cancer Treatment, Laser Technology, and Climate Research
Today's science news brings breakthroughs across medicine, technology, and Earth science.
Pancreatic Cancer Treatment Breakthrough
Researchers have developed daraxonrasib, a new drug that targets the KRAS mutation driving most pancreatic tumors. In a major clinical trial, the treatment nearly doubled survival for patients with advanced disease and reduced the risk of death by 60%.

Atlantic Ocean Circulation Weakening
A unique cooling patch southeast of Greenland may indicate that the Atlantic Meridional Overturning Circulation (AMOC) — often called the ocean's 'conveyor belt' — is weakening, making it the only region on Earth showing temperature decline.

Wildfire Smoke Increases Ground-Level Ozone
A NASA-funded study has found that over the past decade, wildfires have significantly increased ground-level ozone pollution across much of the contiguous United States, creating unhealthy air quality in areas far from active fires.
