NASA confirms heavy rainfall, strengthening of tropical storm Marie

Tropical Storm Marie has formed in the Eastern Pacific Ocean and NASA satellite data helped confirm the strengthening of the storm. In addition, using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Marie's rainfall rates the provided more clues about intensification.

Disease-spreading ticks keep marching north as weather stays warmer

Ticks are among nature's most hardy survivors. They've been around for at least 100 million years and used to feast on dinosaur blood. Their bodies contain anti-freeze to help them survive cold weather and their two front legs have carbon dioxide and infrared sensors to help detect when a warm-blooded mammal is approaching. Tiny hairs on their legs increases friction and allows ticks to latch onto...

Developing the fastest and most sensitive graphene microwave bolometer

Bolometers are devices that measure the power of incident electromagnetic radiation thru the heating of materials, which exhibit a temperature-electric resistance dependence. These instruments are among the most sensitive detectors so far used for infrared radiation detection and are key tools for applications that range from advanced thermal imaging, night vision, infrared spectroscopy to...

Stellar explosion in Earth's proximity, eons ago

When the brightness of the star Betelgeuse dropped dramatically a few months ago, some observers suspected an impending supernova - a stellar explosion that could also cause damage on Earth. While Betelgeuse has returned to normal, physicists have found evidence of a supernova that exploded near the Earth around 2.5 million years ago.

AIOps uses AI, automation to boost security

When the 2020 coronavirus pandemic forced workers across the United States to stop congregating in offices and work from home, Siemens USA was prepared to protect its newly remote workforce and identify and repel potential data breaches. It turned to AIOps—artificial intelligence for IT operations—and a specialized security system to immediately secure and monitor 95% of its 400,000 PCs,...

Strand of DNA inherited by modern humans is linked to likelihood of falling severely illCoronavirus – latest updatesSee all our coronavirus coverageModern humans and Neanderthals could be forgiven for having other issues on their minds when they interbred in the stone age. But according to researchers, those ancient couplings laid a grim foundation for deaths around the world today.Scientists...

Millions of Latinos at risk of job displacement by automation

The potential acceleration of job automation spurred by COVID-19 will disproportionately affect Latinos in U.S. service sector jobs, according to a new UCLA report, which also urges state and local officials to start planning now to implement programs to support and retrain these workers.
