The Mediterranean Sea Is So Hot, It’s Forming Carbonate Crystals

It’s also worth noting that the Mediterranean Sea is one of the most microplastic-polluted water bodies in the world: In 2020, scientists reported finding 2 million particles in a single square meter of sediment that was only 5 centimeters thick. Whether aragonite crystals are forming around microplastics floating in the water column, Bialik doesn’t know. … Read more

Scientists Show Transmission of Epigenetic Memory Across Multiple Generations

A new research study reveals how a common type of epigenetic modification can be transmitted via sperm not only from parents to offspring, but to the next generation (“grandoffspring”) as well. Changing the epigenetic marks on chromosomes results in altered gene expression in offspring and in grandoffspring, demonstrating ‘transgenerational epigenetic inheritance.’ Without changing the genetic … Read more

Asteroid that killed the dinosaurs made mile-high tsunami

Scientists have discovered that the near 9-mile diameter asteroid that wiped out the dinosaurs also triggered a “mile high” tsunami that spread across the globe, according to EurekAlert. Researchers from the University of Michigan studied the asteroid’s impact site in Mexico’s Yucatan peninsula — along with 100 other locations around the globe — and managed … Read more

Discovering faster matrix multiplication algorithms with reinforcement learning

TensorGame TensorGame is played as follows. The start position (mathscrS_0) of the game corresponds to the tensor (mathscrT) representing the bilinear operation of interest, expressed in some basis. In each step t of the game, the player writes down three vectors (u(t), v(t), w(t)), which specify the rank-1 tensor u(t) ⊗ v(t) ⊗ w(t), and the state of the … Read more
