An analysis of studies incorporating data from almost 30 million people has highlighted the role that air pollution — including that coming from car exhaust emissions — plays in increased risk of dementia.

A soft artificial muscle has been developed by Northwestern University engineers wherein it provides the performance and mechanical properties required for building robotic musculoskeletal systems.

To outpace rising antibiotic resistance, researchers at Rockefeller University have developed a platform that scans environmental DNA to identify resistance genes before they reach the clinic, helping design antibiotics that are built to last.

A new study using AI and satellite radar data shows that strongly protected marine areas are largely free from industrial fishing. The findings suggest that no-take zones are more effective than previously thought, offering a promising tool for ocean conservation and supporting global biodiversity targets.

A widely anticipated clinical trial has delivered disappointing results: the antiviral drug valacyclovir, commonly used to treat herpes infections, showed no benefit in slowing early-stage Alzheimer’s.

Too many pills, too many risks: A new tool developed by McGill University researchers helps clinicians identify and safely reduce unnecessary medications in older adults. In a major trial, the Medsafer software nearly tripled the success rate of deprescribing in long-term care—offering new hope for safer, more responsive care in aging populations.

How do we taste sweetness? Researchers at St. Jude have captured the sweet taste receptor in action — revealing a newly discovered “loose” state that may be key to designing better sweeteners.

A new study has revealed that scientists were able to block a newly discovered anaphylaxis pathway in mice by making use of the Zileuton drug. With this, they have now kick-started a clinical trial to test if the drug can replicate the same process in humans.

Northwestern University researchers have uncovered how carbohydrates in organic matter form water “bridges” with soil minerals, locking in moisture even under extreme drought, a finding that could transform soil management on Earth and inform studies of water retention on other planets.

Just 15 minutes in nature can ease anxiety, lift mood, and boost mental well-being — even in the heart of a city. A new Stanford-led study shows how small doses of green space offer big mental health benefits, especially for young adults.
