NASA-NOAA satellite finds Hurricane Delta rapidly intensifying

Infrared imagery from NASA-NOAA's Suomi NPP satellite revealed that Hurricane Delta has been rapidly growing stronger and more powerful. Infrared imagery revealed that powerful thunderstorms circled the eye of the hurricane and southern quadrant as it moved through the Caribbean Sea on Oct. 6.

Evolution of the Y chromosome in great apes deciphered

New analysis of the DNA sequence of the male-specific Y chromosomes from all living species of the great ape family helps to clarify our understanding of how this enigmatic chromosome evolved. A clearer picture of the evolution of the Y chromosome is important for studying male fertility in humans as well as our understanding of reproduction patterns and the ability to track male lineages in the...

UK to buy 1m antibody home tests despite accuracy concerns

Scientists question purchase of tests from British consortium before evaluation made publicThe Department of Health has announced it is buying 1m home antibody tests from a British consortium, even though experts say the only data published about them raises major questions about their accuracy.The government is spending millions of pounds on the tests, made by the UK Rapid Test Consortium. The...

Revising climate models with new aerosol field data

Smoke from the many wildfires burning in the West have made air quality hazardous for millions of people in the United States. And it is the very tiniest of the aerosol particles in that air that make it particularly harmful to human health. But for decades, we haven't known how long these particles actually stay aloft.

Experiments with twisted 2-D materials catch electrons behaving collectively

Scientists can have ambitious goals: Curing disease, exploring distant worlds, clean-energy revolutions. In physics and materials research, some of these ambitious goals are to make ordinary-sounding objects with extraordinary properties: Wires that can transport power without any energy loss, or quantum computers that can perform complex calculations that today's computers cannot achieve. And the...

Evidence of Alzheimer's, Parkinson's and MND in brains of young people exposed to dirty air

After examining the brainstems of 186 young Mexico City residents aged between 11 months and 27 years of age, researchers, found markers not only of Alzheimer's disease, but also of Parkinson's and of motor neuron disease (MND) too. These markers of disease were coupled with the presence of tiny, distinctive nanoparticles within the brainstem - their appearance and composition indicating they were...

Remote control of blood sugar: Electromagnetic fields treat diabetes in animal models

Researchers may have discovered a safe new way to manage blood sugar non-invasively. Exposing diabetic mice to a combination of static electric and magnetic fields for a few hours per day normalizes blood sugar and insulin resistance. The unexpected and surprising discovery raises the possibility of using electromagnetic fields (EMFs) as a remote control to manage type 2 diabetes.

Are Astronaut-Style Face Shields the Future of PPE?

"If you have to sneeze, you're in trouble," Bill Johnson said of wearing the Air, an acrylic visor that evokes 1960s Soviet cosmonaut culture. Johnson, 44, a voice and video engineer in Utah, had tested an early model of the device on an airplane from Salt Lake City to Seattle to Ketchikan, Alaska, then on a three-hour ferry ride and a floatplane to reach his bush cabin."I flew...
