Researchers Develop Fast-Charging Self-Heating Lithium-Ion Battery

Posted: 06 Nov 2019 11:14 AM PST

A team of researchers at the Pennsylvania State University has demonstrated that they can charge an electrical vehicle in 10 minutes for a 200 to 300 mile (300-500 km) range. Lithium-ion batteries degrade when rapidly charged at ambient temperatures under 50 degrees Fahrenheit (10 degrees Celsius) because, rather than the lithium ions smoothly being inserted […]
Signs of Ancient Microbes Found within 381-Million-Year-Old Crater

Posted: 06 Nov 2019 10:03 AM PST

Fractured rocks of impact craters may be suitable hosts for deep microbial communities on Earth and potentially other terrestrial planets, yet direct evidence has remained elusive. Now, a team of researchers from the Linnaeus University and elsewhere has found evidence for ancient microbial life in rock samples from the Siljan impact crater in Sweden. The […]
High-Intensity Aerobic Exercise Enhances Memory in Older Adults

Posted: 06 Nov 2019 08:00 AM PST

High-intensity interval training results in the greatest memory performance in inactive older adults compared to moderate training or stretching, according to new research from McMaster University. “There is urgent need for interventions that reduce dementia risk in healthy older adults,” said study senior author Dr. Jennifer Heisz, a researcher in the Department of Kinesiology at […]
Beautiful New Species of Dragonfly Discovered

Posted: 06 Nov 2019 05:32 AM PST

A new species of dragonfly, officially named Gynacantha vargasi, has been discovered on the Caribbean slope of Costa Rica. The newly-discovered species belongs to the genus Gynacantha, a group of almost 100 species distributed through the tropics and subtropics of the New World, Africa, Asia, and the western Pacific. In the New World, these dragonflies […]
TESS Captures Breathtaking Panorama of Southern Sky

Posted: 06 Nov 2019 04:39 AM PST

Constructed from 208 images taken by NASA’s Transiting Exoplanet Survey Satellite (TESS) during its first year of science operations, completed on July 18, 2019, this mosaic (high-resolution version) reveals both the beauty of the cosmic landscape and the reach of the spacecraft’s cameras. Within this scene, TESS has discovered 29 exoplanets (including three small planets […]
