About 4.5 billion years ago, a colossal impact between the young Earth and a mysterious planetary body called Theia changed everything—reshaping Earth, forming the Moon, and scattering clues across space rocks. By examining subtle isotopic fingerprints in Earth and Moon samples, scientists have reconstructed Theia’s possible composition and birthplace.

A University of Toronto study found that nearly one in four adults aged 60+ who reported poor well-being were able to regain optimal wellness within three years. The research highlights that physical activity, healthy weight, good sleep, and emotional and social support play crucial roles in recovery. Those with strong psychological wellness at the start were five times more likely to bounce back. Source link
Researchers uncovered how fatty molecules called ceramides trigger acute kidney injury by damaging the mitochondria that power kidney cells. By altering ceramide metabolism or using a new drug candidate, the team was able to protect mitochondrial function and completely prevent kidney injury in mice. Source link
Researchers found that tau proteins don’t jump straight into forming Alzheimer’s-associated fibrils—first they assemble into soft, reversible clusters. When the clusters were dissolved, fibril growth was almost entirely suppressed. This reveals a promising new strategy: stop the precursors, stop the disease. Source link
