Researchers have developed a new tool and technique that uses “vortex ultrasound“ – a type of ultrasonic tornado – to break down blood clots in the brain. The new approach works faster than existing techniques to eliminate clots formed in an in vitro model of cerebral venous sinus thrombosis, or CVST. The U.S. National Science … Read more

New research by Joanna Blaszczak of the University of Nevada, Reno and her colleagues shows that hypoxia in rivers and streams is more prevalent across the globe than previously thought. Hypoxia occurs when oxygen levels in surface waters become depleted, which can be harmful to aquatic species and can increase production of greenhouse gases from … Read more

A startling analysis from Globe at Night — a citizen science program run by the U.S. National Science Foundation NOIRLab — concludes that stars are disappearing from human sight at an astonishing rate. The study finds that, to human eyes, artificial lighting has dulled the night sky more rapidly than indicated by satellite measurements. The … Read more

A team led by University of Minnesota Twin Cities researchers has invented a groundbreaking catalyst technology that converts renewable materials such as trees and corn into acrylic acid and acrylates, the key chemicals used in paints, coatings and superabsorbent polymers. The new technology is highly efficient and could lead to lower costs for manufacturing renewable … Read more

The next frontier of continuous health monitoring could be skin deep. Biomedical engineers at the University of Cincinnati say interstitial fluid, the watery fluid between and around cells, tissues and organs in the body, could provide an excellent medium for early disease diagnosis or long-term health monitoring. A U.S. National Science Foundation-supported paper published in … Read more

The U.S. National Science Foundation, in partnership with Australia’s national science agency, CSIRO, is announcing grants totaling $1.8 million on the U.S. side and $2.3 million on the Australian side to accelerate groundbreaking research in responsible and ethical artificial intelligence solutions to societal challenges, including pandemic preparedness, drought resilience and harmful environmental emissions. Responsible and … Read more

It’s estimated that the information, communication and technology sector accounts for 5% to 9% of total electricity consumption worldwide. If growth continues unabated, computing could demand up to 20% of the world’s power generation by 2030. With power grids already under strain, engineers at the University of Virginia are investigating a system that will allow … Read more

The rapid retreat of Thwaites Glacier in West Antarctica appears to be driven by processes under its floating ice shelf that are different than researchers realized. Two papers published in the journal Nature provide a clearer picture of the changes taking place under the glacier, which is the size of Florida and is one of … Read more

A study led by scientists at The University of Texas at Austin is providing a glimpse into dinosaur and bird diversity in Patagonia during the Late Cretaceous, just before the non-avian dinosaurs went extinct. The fossils represent the first record of theropods — a dinosaur group that includes both modern birds and their closest non-avian … Read more

Lizards living in different cities have parallel genomic markers when compared to neighboring forest lizards, according to a new study published in Proceedings of the National Academy of Sciences. The genetic variations linked to urbanization underlie physical differences in the urban lizards, including longer limbs and larger toe pads that show how these lizards have … Read more
