A flood of new research is reshaping what we know about human longevity, with studies linking diet, vitamin D, and belly fat to dramatically different survival odds — and one controversial finding may have you reconsidering your protein intake. Scientists have uncovered a hidden immune cell attack route against one of the hardest-to-treat blood cancers, while a separate discovery reveals how an ancient protein older than blood circulation itself could supercharge modern cancer immunotherapy. On the cosmic and quantum fronts, researchers have spotted never-before-seen plasma whirlpools on the Sun's surface and engineered a microscopic gold crystal that could make quantum computing work at room temperature. Meanwhile, stunning new evidence from a Turkish cave is rewriting the story of how modern humans and Neanderthals may have shared not just space, but culture and ideas across thousands of years.
