1. Watch Live: NASA’s Crew-13 could make the fastest U.S. trip to the ISS ever

   NASA’s SpaceX Crew-13 mission is scheduled to launch four astronauts to the International Space Station on October 1. The Dragon could reach the orbiting laboratory in just 7 hours and 50 minutes, making it the fastest U.S. spacecraft journey to the ISS in history.

2. Cannabis users were twice as likely to commit violence, review finds

   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.

3. A record-breaking X-ray flash may reveal the birth of a magnetar

   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.

4. Quantum teleportation breakthrough: Scientists crack a 25-year entanglement challenge

   Scientists have developed and experimentally demonstrated a long-sought method for identifying W states, an important form of multi-photon quantum entanglement. The technique could make complex entangled systems much easier to measure, opening new possibilities for quantum teleportation, communication, and computing.

5. Sharks can hear nearly 250 feet away and pinpoint the source

   Wild blacktip sharks can detect low-frequency sounds from nearly 250 feet away, according to experiments conducted off the Florida coast. The sharks not only heard the sounds but sharply changed direction away from them, suggesting they could pinpoint where they were coming from.
