Scientists describe earliest primate fossils

The study documents the discovery of Purgatorius fossils, which are estimated to be 65.9 million years old, providing insight into primates' evolution and diversification after the Cretaceous-Paleogene extinction event. The findings suggest that primates likely emerged by the Late Cretaceous period and lived alongside large dinosaurs.

Lasers & molecular tethers create perfectly patterned platforms for tissue engineering

Scientists at the University of Washington develop a technique to modify biological polymers with protein-based biochemical messages, triggering cell behavior. The approach uses near-infrared lasers to attach proteins to scaffolds made from collagen or fibrin, creating intricate patterns that control cell growth and signaling.

New treatment allows some people with spinal cord injury to regain hand and arm function

Researchers at the University of Washington developed a new treatment that uses skin-surface stimulation to help people with spinal cord injuries regain hand and arm mobility. After a five-month training program, six participants showed significant improvements in hand function, which lasted for up to six months after treatment ended.

How a police contact by middle school leads to different outcomes for Black, white youth

A new University of Washington study examines the effects of early police contacts on Black and white adolescents, finding that Black youth are more likely to be treated as 'usual suspects' after a first encounter, leading to subsequent arrests. White youth with early police contact are not significantly more likely to be arrested later.

Are climate scientists being too cautious when linking extreme weather to climate change?

Researchers argue that current approaches to attributing extreme weather events to global warming focus too much on raising the threshold for false alarms, neglecting the importance of accurate warnings. By prioritizing probability of detection, climate scientists can strike a better balance between caution and timely warning.

Airdropping sensors from moths

University of Washington researchers develop a 98mg sensor system that can be released from drones or insects and land safely without breaking, collecting data for almost three years. The system uses a magnetic pin to hold the sensor, which is then released using a wireless command, allowing for remote monitoring in hard-to-reach areas.
