A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older. Participants spent just a few minutes a day on brain-training activities, and researchers found measurable gains across multiple aspects of brain health, including thinking clarity, emotional well-being, and sense of purpose.

The aging of the innermost cell layer of blood vessels leads to cardiovascular diseases. Researchers have now shown for the first time that intestinal bacteria and their metabolites contribute directly to vascular aging. As people age, the bacterial composition in their gut changes, resulting in fewer 'rejuvenating' and more harmful substances in the body. Read more ›

Many bat species native to Germany, such as the Leisler's bat, are forest specialists. However, as it is becoming increasingly hard for them to find tree hollows in forest plantations, so they are moving to settlements instead. Using high-resolution GPS data from bats, a team led by scientists has analyzed in greater detail than ever before how Leisler's bats use their habitats, which tree species they look for when searching...

A new study reveals the biological secret to the Zika virus's infectious success: Zika uses host cells' own 'self-care' system of clearing away useless molecules to suppress the host proteins that the virus has employed to get into those cells in the first place. Read more ›

A team analyzed a range of YouTube videos that focused on learning music by ear and identified four simple ways music learning technology can better aid prospective musicians -- helping people improve recall while listening, limiting playback to small chunks, identifying musical subsequences to memorize, and replaying notes indefinitely.

Laser-based metal processing enables the automated and precise production of complex components, whether for the automotive industry or for medicine. However, conventional methods require time- and resource-consuming preparations. Researchers are now using machine learning to make laser processes more precise, more cost-effective and more efficient. Read more ›

Researchers conducted a systematic review of 99 scientific publications that compared the flora or fauna of old-growth forests, managed forests and clearcut sites in boreal Europe. The reviewed studies showed large differences in the species communities inhabiting these forest types. The species richness of full-canopy forests increases as the forest gets older. Clearcut sites are also species-rich, but they are inhabited by a distinct set of species in comparison to... Read more ›
