Bush fire season is underway again in Australia, where summer has just kicked off. Yet the country is still recovering from record-breaking wildfires two years ago that killed at least 33 people, destroyed thousands of homes and burned more than 65,000 square miles of land. How quickly the natural landscape recovers depends on the climate … Read more
A computer simulation tracks 9 million years of evolution within a stellar nursery – also known as a giant molecular cloud – in which stars are born Space 11 January 2022 By Chen Ly The most detailed simulations to date of giant molecular clouds (GMCs) hint that we may need to rethink our understanding of … Read more
For most of life on Earth, oxygen is essential, and sunlight is usually needed to produce that oxygen. But in an exciting twist, researchers have caught a common, ocean-dwelling microbe breaking all the rules. Scientists have found that a microbe called Nitrosopumilus maritimus and several of its cousins, called ammonia oxidizing archaea (AOA), are able to … Read more
CAPE CANAVERAL, Fla. — NASA’s newest space observatory, the Imaging X-ray Polarimetry Explorer (IXPE), is set to begin spying on some of the universe’s most dramatic objects — black holes and neutron stars — potentially changing our understanding of the cosmos in the process. The 730-pound (330 kilograms) IXPE satellite launched to orbit on Dec. … Read more

Random numbers – a vital part of encryption – are hard for computers to generate, but a new trick turns memory chips into a source of random noise Technology 11 January 2022 By Matthew Sparkes A DRAM memory chip on a circuit board B Christopher / Alamy Computers struggle to create randomness, but a new … Read more
One of humanity’s most powerful Earth-observing satellites is having some problems in orbit. The Sentinel-1B radar satellite, part of the European Union’s Copernicus Earth observation program, hasn’t beamed home any data since suffering an anomaly on Dec. 23. And the problem appears to be relatively serious. “Following the previous news on the Sentinel-1B anomaly that … Read more
Astronomers have found evidence of a black hole snacking on a star in data gathered back in the 1980s, according to new research. The researchers say that they have identified the signature of such an event in data gathered during the 1980s, thanks to a pair of high school interns from Massachusetts. When a star … Read more
