In California, 41 out of 58 counties are now officially under drought conditions.

Australian-first research by Monash University discredits the theory that rivers and underground water supplies eventually replenish following droughts or floods. Following the Australian Millennium Drought, one-third of Victoria's water catchments still had not recovered from drought nearly eight years later. For those water catchments not recovered, roughly 80 per cent showed no evidence of recovering anytime soon.

QUT air-quality expert Distinguished Professor Lidia Morawska is leading an international call for a "paradigm shift" in combating airborne pathogens such as COVID-19, demanding universal recognition that infections can be prevented by improving indoor ventilation systems.

"Help! I'm fishing and just caught a huge sea turtle. She's completely swallowed my hook." We are two veterinarians, Debra Moore, who specializes in sea turtles, and John Thomason, who specializes in internal medicine. This is a call we get a lot in our work with the Sea Turtle Stranding and Salvage Network.

U.S. officials said Thursday that they will try to stamp out wildfires as quickly as possible this year as severe drought tightens its grip across the West and sets the stage for another destructive summer of blazes.

In the months before the pandemic, I was involved in an extensive piece of research into the sex work industry in the UK. Focusing on the main online market for sex work in the UK, AdultWork, we analyzed the profiles of more than 11,500 sex workers to understand the industry and how it operates online.

When a piece of conducting material is heated up at one of its ends, a voltage difference can build up across the sample, which in turn can be converted into a current. This is the so-called Seebeck effect, the cornerstone of thermoelectric effects. In particular, the effect provides a route to creating work out of a temperature difference. Such thermoelectric engines do not have any movable part and are therefore convenient power sources in various applications, including propelling NASA's Mars rover Perseverance. Читать дальше...

Elon Musk's SpaceX announced Thursday that Google would team up with its Starlink satellite internet service to deliver cloud computing services to business customers.

Astronomers commonly refer to massive stars as the chemical factories of the Universe. They generally end their lives in spectacular supernovae, events that forge many of the elements on the periodic table. How elemental nuclei mix within these enormous stars has a major impact on our understanding of their evolution prior to their explosion. It also represents the largest uncertainty for scientists studying their structure and evolution.

Russia said Thursday it would send an actress and a director into space to make the first feature film in the cosmos and also deliver an eccentric Japanese billionaire to the International Space Station.

This weekend, a Chinese rocket booster, weighing nearly 23 tons, came rushing back to Earth after spending more than a week in space—the result of what some critics, including NASA Administrator Bill Nelson, have attributed to poor planning by China. Pieces of the rocket, dubbed Long March 5B, are believed to have splashed down in the Indian Ocean near the Maldives, and no one was injured.

The latest federal stimulus package included funding for K-12 school districts across the country to use specifically for combatting learning losses resulting from the pandemic.

In a new report in NPG Asia materials, Chisa Norioka and a team of scientists in Chemistry and Materials Engineering in Japan, detailed a universal method to easily prepare tough and stretchable hydrogels without special structures or complications. They tuned the polymerization conditions to form networks with many polymer chain entanglements, to achieve energy dissipation throughout the resulting materials. The team prepared the tough and stretchable hydrogels via free radical polymerization using... Читать дальше...

A team of researchers from the National Institute of Polar Research, the University of California, Santa Cruz and the University of North Carolina has found that adult female northern elephant seals dive deep into the ocean to forage for small fish for up to 18 hours a day. In their paper published in the journal Science Advances, the group describes their study of the large sea creature, which involved capturing specimens and attaching a camera and sensors to their bodies.
