A 30-year forestry experiment in Australia found that heavily thinned mountain ash forests grew unusually large trees while recovering enough carbon to match or exceed untouched areas. The results suggest carefully managed thinning could support timber production, wildlife habitat, and carbon storage at the same time.
A UCLA study links faster brain aging to specific gut bacteria and chemical byproducts, with older-looking brains also associated with poorer memory, focus, and mood. The findings suggest that biological signs of brain aging may appear decades before obvious symptoms and could eventually make the gut a target for prevention.
Working from before dawn until midnight, farmers Nikoletta Pajsan Nagy and Laszlo Pajsan fought Europe's driest summer ever to save their red pepper harvest in Hungary.
A new light-activated material can efficiently produce hydrogen from water without requiring an additional expensive metal catalyst. Researchers say its unusual sulfur-based chemistry could point toward cheaper and more practical ways to turn sunlight into clean fuel.
The picturesque Lac des Brenets between France and Switzerland has dried up after a record-breaking hot summer, leaving locals crying out for help to save the lake.
High-dose vitamin B3 is showing intriguing early promise as an addition to standard glioblastoma treatment, with 82% of patients in a small trial remaining progression-free after six months. Researchers believe niacin may help revive immune cells suppressed by the cancer, but larger studies are still needed to confirm the benefit and safety.
Earth glows like a half moon while a giant aurora writhes over the North Pole in this ultraviolet image from the new Smile spacecraft. (Image credit: ESA & CAS/Smile/UVI CC BY-SA 3.0 IGO)Quick factsWhat it is: An aurora on the sunlit side of EarthWhere it is: Over the North Pole, as seen from about 75,000 miles awayWhen it was shared: Sept. 30The debut images from a new Earth-observing satellite have just given us a view of the impossible: giant auroras rippling over the North Pole in broad daylight. Earth's auroras are one of our planet's signature wonders — a sight worth advertising in interstellar travel guides, alongside our perfect total solar eclipses, bright shooting stars and majesti...
Attachment is the term psychologists use for the most significant relationships that hold people’s lives together
In 2023, an African gray parrot named Jack went viral for mimicking the coughs and wheezes of her owner's father, who often struggled to breathe from severe chronic obstructive pulmonary disease. But it wasn't just the imitation that made Jack famous; it was also that she seemed to relish the suffering of a man she purportedly hated. In the video, Jack's owner even claimed that she had a favorite cough.The parrot appeared to be experiencing a complex emotion that in humans is known as schadenfreude, or pleasure at seeing another's pain. Literally translated from German as "harm joy," it's a feeling that might emerge when a rival coworker gets fired, or when a rude neighbor has their package ...
A vitamin D analog may help break down pancreatic cancer’s protective defenses, potentially making tumors more vulnerable to chemotherapy and immune attack. A small clinical trial found encouraging responses, especially in patients whose tumors had high levels of the vitamin D receptor.
A two-year randomized clinical trial involving 493 adults with overweight or obesity found that diet soft drinks were essentially as effective as water for long-term weight loss and weight maintenance. Participants drinking beverages sweetened with aspartame, acesulfame-K, or sucralose lost a similar amount of weight to those drinking water, while both groups also saw improvements in waist size, body composition, and several metabolic measures.
Americans are crazy about sports. But whether that passion requires taxpayers to subsidize new facilities every time leagues and franchises ask for them needs rigorous scrutiny.
