As Climate Hazards Rise, Scientists Predict Disasters Before They Happen

For climatologists examining a temperature forecast map of the Pacific Ocean in November, a bright red “V” on the side, thousands of miles long, signaled disaster. Combined with La Nina cooling in the central and eastern Pacific, the V-shaped pattern of warm seawater, stretching from the east coast of Australia to the Philippines and returning to the ocean at north of Hawaii, said halfway around the world in the Horn of Africa the next rainy season from March to May would likely fail.

Stellar ‘vampire’ finds love at first bite with fellow star

Astronomers have seen what happens when a “vampire” star sucks the outer layers of material from a companion star, stripping that “bitten” victim into a simple stellar core. Researchers said on Wednesday that data obtained using Chile-based European Southern Observatory (ESO) telescopes clarified the nature of a star system called HR 6819, showing that its two companion stars were not accompanied by a black hole as previously proposed.

Latest NOAA weather and fire-tracking satellite launched into orbit

An Atlas V rocket lifted off from Florida on Tuesday carrying into orbit the next big satellite designed by the National Oceanic and Atmospheric Administration (NOAA) to provide round-the-clock monitoring of weather, wildfires and climate change in the western hemisphere of the Earth. The GOES-T spacecraft is the third in the latest series of advanced geostationary satellites credited with revolutionizing real-time weather forecasting, environmental monitoring and hazard detection from space.

Seals help Japanese researchers collect data under Antarctic ice

A seal wearing a helmet with an antenna might seem unusual, but eight Weddell seals, each with a 580g tracking device on their heads, helped Japanese researchers probe the waters beneath the thick Antarctic ice cap . Exploited for a research project between March and November 2017 – winter in Antarctica – these seals were equipped with the head-mounted conductivity, temperature and depth sensor, which allows scientists to collect observational data, such as water temperature and salt levels, in areas with extremely harsh environmental conditions.

Scientist uses tiny trackers to keep tabs on funnel-web spiders

Some Sydney funnel-web spiders scurry through Australian scrub carrying special cargo: a telemetry tracker to study how far a mature male can travel at night and whether his movements are affected by environment and weather. Caitlin Creak, a doctoral student in the School of Biological, Earth and Environmental Sciences at the University of New South Wales, has been tracking the male Sydney funnel-web spider, one of the deadliest spiders, for two summers. in the world. The nocturnal arachnid lives about 100 km (62 miles) from Australia’s largest city and is most active between November and April.

Redhill antiviral shows promise in safety study; J&J fired less effectively to prevent hospitalization

Here is a summary of some recent studies on COVID-19. They include research that deserves further study to corroborate the findings and that has not yet been certified by peer review. Redhill drug blocks proteins that help coronavirus
