Antarctic ice preserves traces of iron-60 from ancient stellar explosions, helping scientists track the Solar System’s movement through interstellar clouds and changing cosmic environments. When you think of outer space, you’re likely picturing stars, planets, and moons. But much of space is filled with clouds of gas, plasma, and stardust—known as interstellar clouds. In the […]

A 400-Degree Mystery Is Hiding Deep Inside Mars
Scientists have found a vast hidden heat imbalance inside Mars, with the southern interior hundreds of degrees hotter than the north and possibly partially molten. Scientists have discovered a major temperature imbalance deep inside Mars, with the planet’s southern interior appearing dramatically hotter than the north. Gravity measurements suggest that the interior beneath Mars’s southern […]
Major Trial Tests a New Way To Decide Who Really Needs Statins
A heart scan led to far fewer statin recommendations and much higher medication adherence, but a major trial could not prove the strategy was as protective as traditional risk scoring. Who should start taking a statin before a heart attack or stroke ever happens? Doctors typically estimate that risk using factors such as cholesterol, blood […]

Scientists Used Cancer Therapy To Reset Rheumatoid Arthritis
After years of failed treatments, a single infusion of genetically reprogrammed immune cells sent severe rheumatoid arthritis into lasting, medication-free remission in several patients. Rheumatoid arthritis begins when the immune system turns against the tissue lining the joints. The resulting inflammation causes pain, stiffness, and swelling and can gradually erode cartilage and bone. Available medications […]
A Century-Old Physics Effect Just Got a New Dimension
Physicists have uncovered an in-plane Hall response that overturns a century-old assumption about how this famous electrical effect works. The discovery could eventually make multidirectional magnetic sensing possible with one tiny device. Scientists at Carnegie Mellon University have identified an unexpected form of the Hall effect that challenges a long-standing assumption about how electronic materials […]
