A team of researchers from Sydney’s University of New South Wales and the South Australian Museum have investigated how the reversal of Earth’s magnetic pole about 42,000 years could have changed earth’s atmosphere. CNN reports: “Using the ancient trees we could measure, and date, the spike in atmospheric radiocarbon levels caused by the collapse of Earth’s magnetic field,” Chris Turney, a…

WHO Investigators Now Believe Cornavirus was ‘Circulating Widely’ in Wuhan in December
“Investigators from the World Health Organization (WHO) looking into the origins of coronavirus in China have discovered signs the outbreak was much wider in Wuhan in December 2019 than previously thought,” reports CNN, “and are urgently seeking access to hundreds of thousands of blood samples from the city that China has not so far let them examine.” The lead investigator for…

Meet PitRanger: Tiny rover designed to probe the lunar underworld
Researchers have been busily building a prototype of a 33-pound (15 kg) lunar mini-robot, set to be the key instrument in a future mission aimed at capturing high-definition images of moon pits. Source: https://earthsky.org/space/meet-pitranger-a-tiny-rover-to-probe-lunar-underworld…
America Creates a 770-Mile Corridor for Testing Supersonic Aircraft Up to Mach 3
America’s Federal Aviation Agency signed an agreement with the state of Kansas’s department of transportation to establish a 770-nautical mile Kansas Supersonic Transportation Corridor for testing aircraft up to Mach 3, reports Aviation International News:
The agreement would provide a critical testing site for the emerging group of supersonic aircraft as civil supersonic flight remains banned over land. Flight testing for models…
C1-23152: An ancient galaxy that built itself
A popular theory of galaxy formation suggests that small galaxies merged to form larger ones. But galaxy C1-23152 – 12 billion light-years from Earth – apparently formed itself from gas in the early universe, via exceedingly rapid star formation.

Accurate theoretical modeling unravels changes in molecules interacting with quantum light
A team of researchers from Italy, Norway, and Germany has demonstrated that the properties of molecules undergo significant changes when interacting with quantized electromagnetic fields in optical cavities. Using novel theoretical methodologies and computational simulations, the team revealed that the ground- and excited-state chemistry of molecules can be modified by a confinement in space. They show how the transfer of electrons…
Massive supercontinent will form hundreds of millions of years from now
Scientists are modeling when Earth’s next supercontinent phase will begin, and how that could affect global climate. Source: https://www.livescience.com/agu-future-earth-supercontinent-climate.html
Are Fragments of Energy the Fundamental Building Blocks of the Universe?
hcs_$reboot shares a remarkable new theory from Larry M. Silverberg, an aerospace engineering professor at North Carolina State University (with colleague Jeffrey Eischen). They’re proposing that matter is not made of particles (or even waves), as was long thought, but fragments of energy. [W]hile the theories and math of waves and particles allow scientists to make incredibly accurate predictions about the…
Exxon Holds Back on Technology That Could Slow Climate Change
Carbon capture can make money for oil giants, and scientists say we need it. Is the industry willing to invest enough? From a report: Elk and pronghorn antelope migrate each fall through southern Wyoming, where the sparsely vegetated landscape slowly gives way to the foothills of the Rocky Mountains. Interrupting this serene vista is a dense web of steel pipes, tanks,…
