A new study by Aalto University found that 76% of young Finns use YouTube daily for music listening. The two services are preferred over CDs, digital files, and other platforms due to their vast music selection and ease of use. Researchers believe the shift towards streaming is a transition from file downloads to online audio streaming.
Researchers found that folic acid supplementation increased nitric oxide production in older blood vessels, improving skin blood flow and reducing cardiovascular risk. This inexpensive alternative to pharmaceutical treatments shows promise for helping older adults cope with environmental heat waves.

The study highlights the need for social support during periods of sexual identity transition.
A recent study from Brown University suggests that video gamers excel in visual tasks, not just due to prior practice, but also because of enhanced learning abilities. Gamers outperformed non-gamers on two consecutive visual task learning exercises by an average of 15% and 11%, respectively.
