Volunteers help make mountain trails accessible for people with disabilities
It takes a group of dedicated volunteers to make sure mountain trails are wide enough so everyone can have fun.

Part-human part-mouse brain developed in science breakthrough
Researchers at Stanford University genetically altered mice to be able to receive and function with human brain cells.

Mice with human brain cells offer a tool to study disease. Ethicists ask: What's next?
Neuroscientists have made a major advance in modeling the human brain in mice, offering a new way to study conditions like cerebral palsy. Ethicists ask if it changes how these mice should be treated.
Scientists turn seawater into fresh water without harmful brine
Scientists have developed a solar-powered desalination system that turns seawater into fresh water while removing nearly all of the leftover salt as a solid instead of producing harmful brine. The self-cleaning technology could also recover valuable minerals such as lithium, potentially turning desalination waste into a useful resource.
Scientists find an immune “false alarm” that may drive rapid aging
Scientists have discovered that some severe genetic disorders linked to rapid aging may be driven not just by damaged DNA, but by the body’s overreaction to that damage. When broken DNA fragments leak into the wrong part of a cell, an immune sensor called cGAS can mistake them for signs of a viral infection, triggering chronic inflammation and even interfering with DNA repair itself.
A 240-million-year-old fossil just changed the dinosaur timeline
A newly identified 240-million-year-old animal from Tanzania is forcing scientists to rethink the early dinosaur timeline. Dinodontosaurus isiyavamanda belongs to a group previously known only from South America, linking fossil deposits on the two continents. That connection suggests Tanzania’s supposed oldest dinosaur fossils may actually be millions of years younger than previously thought.
