English COVID-19 prevalence high but growth slowing: study

The prevalence of COVID-19 infections in England is much higher than it was at the end of August but there are signs that growth in infection rate is slowing, a study by Imperial College said on Thursday. The findings come after Prime Minister Boris Johnson pleaded with Britons to obey the rules imposed to tackle a rapidly accelerating second wave of the coronavirus, with more than 7,000 new...

Global heating warming up 'nights faster than days'

Effect seen across much of world will have profound consequences, warn scientistsThe climate crisis is heating up nights faster than days in many parts of the world, according to the first worldwide assessment of how global heating is differently affecting days and nights.The findings have “profound consequences” for wildlife and their ability to adapt to the climate emergency, the researchers...

No clear link between school opening and COVID surge, study finds

Widespread reopening of schools after lockdowns and vacations is generally not linked to rising COVID-19 rates, a study of 191 countries has found, but lockdown closures will leave a 2020 "pandemic learning debt" of 300 billion missed school days. "It's been assumed that opening schools will drive infections, and that closing schools will reduce transmission, but the reality is much more...

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.
