Researchers from the University of Alberta have found that opioids are best used for acute pain relief for four weeks or less, and may cause more harm than good when used for chronic pain for more than 12 weeks. In a recently published paper in the British Journal of General Practice, the team did a systematic review of 27 randomized controlled trials comparing opioids with non-opioid pain management for the treatment of osteoarthritis or chronic low back pain. The trials examined the ability of opioids such as oxycodone, buprenorphine, oxymorphone, hydromorphone and morphine to produce clinically meaningful pain relief defined as 30 per cent or more over time.

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.
