The rise of artificial intelligence (AI) has changed how people interact, but it also poses a global risk to human dignity, according to new research from Charles Darwin University (CDU). ...
Researchers say the drug likely increases the risk of serious side effects, including heart disease, and that its potential harms probably outweigh any benefits. A large review of existing studies suggests that tramadol, a strong opioid frequently prescribed for chronic pain, offers only limited rel...
Ibuprofen’s anti-inflammatory action may influence cancer risk, but evidence remains complex and routine use for prevention is not advised. Ibuprofen is one of the most widely used pain relievers, commonly taken for headaches, menstrual pain, and other everyday aches. New research suggests that its ...
A long-term study of Brazilian adults found that higher intake of several widely used artificial sweeteners was linked to faster cognitive decline, especially in people under 60 and those with diabetes. Swapping sugar for artificial sweeteners is often framed as an easy health win, but a large new s...
