NASA's Crew-11 mission was cut short and the crew returned to Earth a month early due to an undisclosed medical concern with one astronaut. This marked NASA's first official medical evacuation from space. Despite the early return, the crew completed 140 science experiments on the ISS, contributing to future space exploration.
NASA will transport the Artemis 2 Space Launch System rocket and Orion Module to Launch Pad 39B this weekend for the first crewed lunar mission in fifty years. This 11-million-pound rocket will travel four miles, taking up to 12 hours. The mission, scheduled for an early February launch, will send four astronauts on a 10-day lunar flyby, testing systems for future moon landings.
Research has identified Olowalu, Maui, as the first documented tiger shark mating hub. For six years, acoustic tracking revealed a predictable seasonal convergence of mature males and females. This behavior, coinciding with humpback whale calving, suggests sharks may also be positioning for foraging opportunities. The findings challenge the view of tiger sharks as solely solitary.
Singaporean scientists discovered a new method to disarm antibiotic-resistant bacteria and accelerate chronic wound healing using catalase. This antioxidant enzyme neutralizes hydrogen peroxide produced by bacteria like *Enterococcus faecalis*, which impedes skin cell repair. By blocking this damaging process, catalase restores the cells' ability to migrate and close wounds, offering hope for patients with difficult-to-heal conditions, particularly diabetic foot ulcers.
