In this episode:00:45 A nuclear timekeeper that could transform fundamental-physics research.Nuclear clocks — based on tiny shifts in energy in an atomic nucleus — could be even more accurate and stable than other advanced timekeeping systems, but have been difficult to make. Now, a team of researchers have made a breakthrough in the development of these clocks, identifying the correct frequency of laser light required to make this energy transition happen. Ultimately it’s hoped that physicists could use nuclear clocks to probe the fundamental forces that hold atoms together.News: Laser breakthrough paves the way for ultra precise ‘nuclear clock’10:34 Research HighlightsWhy life on other planets may come in purple, brown or orange, and a magnetic fluid that could change shape inside the body.Research Highlight: Never mind little green men: life on other planets might be purpleResearch Highlight: A magnetic liquid makes for an injectable sensor in living tissue13:48 AlphaFold gets an upgradeDeepmind’s AlphaFol
