Radio astronomy lets scientists 'see' deeper into space - Castanet

What if getting better sleep depends not just on how much you exercise, but how often you move? Research from The University of Texas at Austin suggests that being physically active every day, even for short periods, may help people spend more time in the deep, restorative stages of sleep that support recovery, mood, and mental health. The findings suggest that consistency could be an important but often overlooked part of the relationship between exercise and sleep. Rather than saving all their workouts for the weekend, people may benefit from making movement a regular part of their daily routines.

China's Nobel Prize paradox: The struggle of a scientific powerhouse China’s pursuit of scientific superpower status raises a larger question: Can it build a research environment that attracts talent and rewards long-term curiosity?

Orcas are hunting great White Sharks around the world, scientists confirmThe killing of great whites by orcas has been reported in the waters of South Africa, California, and Australia, and the implications that the hunting behaviour would have on the marine ecosystem have been considered. In fact, it all started back on May 3, 2017, when the body of a female great white, weighing 1,100 kilograms, washed ashore in Gansbaai, close to Cape Town, with a deep gash through which its 90-kilogram liver had been extracted. Five more corpses of great whites appeared with similar wounds in the coming months, as claimed by shark biologist Alison Towner of Rhodes University. Two adult males, called Port and Starboard, who are supposed to be brothers judging by their dorsal fins that fold differently, were identified as the most probable perpetrators. The connection was officially established in 2022 based on video footage of a drone that caught three orcas chasing and biting a 3-meter great white off Mossel Bay. The sharks quickly disappeared from Dyer Island, one of the best places in the world to witness a great white.
