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 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.

Wildlife trust wants marina silt disposed offshore
Brighton Marina wants to restart dredging next year but still needs a site to dispose of the silt.
Scientists recreated what mice saw from brain activity alone
Scientists reconstructed videos from the brain activity of mice, producing 10-second clips based only on signals from neurons in the visual cortex. The breakthrough could help reveal how the brain reshapes what we see before it becomes our perception of reality.

Endangered water voles introduced to reserve
Efforts are being made to reintroduce the locally-extinct species back to the River Wey in Surrey.
