Scientists developed an injection that can repair tissue damage and even reverse paralysis after a spinal cord injury. The therapy triggers the body’s cells to repair themselves and leaves no material behind after 12 weeks.
The Australian Reptile Park received its largest funnel web spider donation ever for its antivenom program, dubbed Megaspider. Megaspider is 8 centimeters long, compared to the average 1–5 centimeters — even its fangs are larger than some funnel web spiders.
Researchers using the ATERUI II supercomputer discovered that planets formed in rings around young stars may move after formation, leaving the rings behind. That could explain why these rings often have large gaps, but planets are rarely found within them.
Researchers found the first fossil evidence of precocious germination — seeds sprouting while still inside their fruit. The researchers observed the condition in a 40-million-year-old pine cone encased in amber.
NASA chose Jessica Watkins as the mission specialist on the upcoming SpaceX Crew-4 mission. Watkins will be the first Black woman to serve on an ISS crew when Crew-4 launches in April 2022.
Researchers developed a mathematical model to compare the CDC’s Covid-19 vaccine rollout with other possible strategies. The study found the actual rollout was one of the most effective, and the model could help with future vaccination drives.
The Hubble Space Telescope captured an image of a protostar forming in nebula IC 2631. These precursors to stars are hard to see without a strong infrared telescope since the dust that surrounds them blocks visible light.
