Episode Details

Scientists have identified a toxic protein pairing in the brain that acts like a hidden death switch, triggering the destruction of neurons and driving Alzheimer's disease — and a new compound may be able to stop it. A team of researchers has reconstructed a galaxy's entire 12-billion-year history using chemical fingerprints from stars, marking a first-of-its-kind breakthrough in galactic archaeology. Moon rock samples sealed since the Apollo 17 mission in 1972 have finally been opened, and the unexpected chemical signatures inside are already challenging what scientists thought they knew about the Moon. Australian scientists have unveiled the world's first quantum battery prototype, which charges faster than anything we've seen before and — defying most known technology — actually becomes more efficient as it scales up. This episode also covers a newly discovered hidden layer of control in human DNA, AI that estimates brain age from sleep data, sperm whale headbutting caught on film, and why your late-night caffeine habit might be making you more impulsive than you realize.
