Researchers at Sweden’s Chalmers University of Technology suggest that frozen hydrogen cyanide may have helped trigger the chemistry that led to life on Earth. Their simulations show HCN forming cobweb-like ice crystals whose reactive surfaces enable unusual chemical reactions even in extreme cold. These processes could generate amino acids, nucleobases and other es...

New observations from the Dark Energy Spectroscopic Instrument are challenging the standard Lambda-CDM model of cosmology. A recent, still-unpublished hypothesis suggests that space itself may behave like a slightly viscous or “sticky” fluid, subtly affecting how the universe expands. By introducing a ghostly resistance to cosmic growth, the model could reconcile ...
