Few of us would turn down a nice cuppa. But over the years, daily decisions between tea or coffee could make a big difference to women's bone health, a recent study suggests. Osteoporosis is a common concern for women over 50 years of age. One in three will be diagnosed with the disease, which occurs when the body fails to replace old bone as it is broken down. This causes bones to become brittle and weak, making them more prone to fractures and harder to heal. Older women are at particular risk of osteoporosis as levels of estrogen, a hormone that supports bone metabolism, drop after menopause. Surgeries to remove a person's ovaries have a similar effect. Public health researchers from Flinders University in Australia analyzed the tea- and coffee-drinking habits of roughly 9,700 US women aged over 65 years, as part of a broader osteoporosis study published in 2025. Participants self-reported their tendencies in surveys conducted on four occasions in a roughly 10-year period.

Orcas are hunting great White Sharks around the world, scientists confirm - Geo News
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.
