Medical Xpress / Statins do not cause the majority of side effects listed in package leaflets, large-scale analysis finds
Statins do not cause the majority of the conditions that have been listed in their package leaflets, including memory loss, depression, sleep disturbance, and erectile and sexual dysfunction, according to the most comprehensive ...
Medical Xpress / RNA therapeutics shrink metastasized lung tumors in mouse study
A new study in mice hints at the potential to use tiny particles made with RNA molecules to deliver chemotherapy drugs and other therapies directly to tumors, killing cancer cells without generating an immune response or ...
Tech Xplore / 'I'm walking here!' A new model maps foot traffic in New York
Early in the 1969 film "Midnight Cowboy," Dustin Hoffman, playing the character of Ratso Rizzo, crosses a Manhattan street and angrily bangs on the hood of an encroaching taxi. Hoffman's line, "I'm walking here!" has since ...
Phys.org / Understanding the hazard potential of the Seattle fault zone: It's 'pretty close to home'
In the Pacific Northwest, big faults like the Cascadian subduction zone located offshore, get a lot of attention. But big faults aren't the only ones that pose significant hazards, and a new study investigates the dynamics ...
Medical Xpress / Addiction and appetite along the gut-brain axis: Vagus nerve may play a crucial role in the dopamine reward pathway
Dopamine—a neurotransmitter responsible for influencing motivation, pleasure, mood and learning in the brain—has experienced a bit of fame in recent years, acting as a sort of buzzword to describe a fleeting satisfaction ...
