A Physicist Bets Against Quantum Gravity
Plus: Microbes survive a fierce desert; A new proof in a sticky problem; An algorithm builds big prime numbers fast; Physics and heart arrhythmia
Abnormal waves of electrical activity can cause a heart's muscle cells to beat out of sync. In this episode, Flavio Fenton, an expert in cardiac dynamics, talks with Steve Strogatz about ways to treat heart arrhythmias without resorting to painful defibrillators.
Producing a prime number on command shouldn't be difficult, but it is. Lijie Chen and others helped develop a new algorithm that uses randomness and determinism to quickly produce reliable large prime numbers.
The Far Side of the Moon Two Chinese orbiters have found a hot spot on the far side of the moon, reports Kenneth Chang for the New York Times. The oddly warm area also contains a large slab of granite, which scientists have considered to be a rarity in our solar system because the rock seems to form through the combined influence of water and plate tectonics. The presence of granite on the moon raises questions about the geochemistry and origins of our natural satellite. In 2017, Rebecca Boyle wrote for Quantaabout the state of theories about how the moon formed.
Neutral Theory and Genetic Drift Paleoanthropologists typically focus on natural selection when studying the evolution of humans. But Lauren Schroeder is studying how nonadaptive processes such as genetic drift influenced our evolution, writes Anna Gibbs for Science News. Scientist have found that these nonadaptive processes play a much larger role in evolution than was previously thought — perhaps even larger than natural selection in some cases. In 2020, Christie Wilcox explained this neutral theory of evolution for Quanta.
