A review of more than 265,000 people found that cannabis use was associated with higher rates of both committing violence and becoming a victim of it. The researchers say the link is significant but does not prove cannabis itself is the cause.
Astronomers have found strong evidence that some mysterious, minutes-long X-ray flashes are produced when two neutron stars collide and create a magnetar. One record-setting event glowed in X-rays for nearly 10 minutes, potentially opening a new way to find these extreme cosmic mergers.
Marine heatwaves may be only the most intense part of much longer warming events, with elevated temperatures sometimes lingering for months. Researchers found that conventional measurements underestimate total heat exposure by more than 150% on average, potentially overlooking a major source of stress on marine ecosystems.
Mulberry compounds may reshape the gut microbiome in ways that support intestinal health and metabolism, with some combinations showing especially strong effects in animal studies. However, the results vary depending on the plant part and processing method, and the benefits have yet to be confirmed in humans.
NASA’s Perseverance rover has uncovered a surprisingly complicated history of water in Jezero Crater. Scientists expected the crater’s Margin Unit to contain lake sediments, but instead found ancient igneous rocks that were altered by water on at least three separate occasions.
