Could cosmic memory explain dark matter, dark energy, and black holes?

A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this cosmic memory could help solve some of the biggest puzzles in physics, from black holes to dark matter and the universe’s ultimate fate.

A surprising discovery reveals the kidney has a secret backup system

Scientists at Mayo Clinic have uncovered a surprising new way the kidneys conserve water, revealing a hidden backup system that works independently of the hormone long believed to control the process. The discovery emerged when researchers testing an old drug called probenecid expected it to worsen polycystic kidney disease (PKD) but found it actually slowed cyst growth instead.

Scientists crack a decades-old CO2 problem and triple fuel production

A new catalyst design could significantly improve the conversion of CO2 into methanol, an important fuel and chemical feedstock. Researchers separated key reaction steps across different catalyst sites, avoiding a long-standing trade-off between speed and efficiency. The result was about three times more methanol production than standard commercial catalysts.

Reversing prediabetes cuts risk of deadly heart problems by 58%

Bringing blood sugar levels back to normal may dramatically reduce the danger posed by prediabetes. Researchers found that people who reversed prediabetes cut their risk of cardiovascular death or hospitalization for heart failure by 58% and lowered their chances of major heart problems such as heart attacks and strokes by 42%. The benefits lasted for decades and were seen across large long-term studies in both the U.S. and China.
