Can 1 cosmic enigma help solve another?

Researchers from Johns Hopkins University suggest that fast radio bursts could provide clues to dark matter by detecting black holes of a specific mass. The team argues that the brief flashes of radio-frequency radiation can detect black holes with masses predicted for dark matter, offering a direct probe of this phenomenon.

How sleep deprivation harms memory

Researchers discover that five hours of sleep deprivation leads to a loss of connectivity between neurons in the hippocampus, a region associated with learning and memory. However, blocking the protein cofilin and allowing recovery sleep restores neuronal connections and improves memory processes.
