HSNW News:

A series of studies, starting as a steady drip and quickening to a deluge, has reported the same core finding amid the global spread of COVID-19: Artificial intelligence could analyze chest images to accurately detect the disease in legions of untested patients.

Casey Ross writes in STAT that the results promised a ready solution to the shortage of diagnostic testing in the U.S. and some other countries and triggered splashy press releases and a cascade of hopeful headlines.

AGU News:

New research finds soot from global fires ignited by an asteroid impact could have blocked sunlight long enough to drive the mass extinction that killed most life on Earth, including the dinosaurs, 66 million years ago.

The Cretaceous–Paleogene extinction event wiped out about 75 percent of all species on Earth. An asteroid impact at the tip of Mexico’s Yucatán Peninsula caused a period of prolonged cold

AGU News:

WASHINGTON, D.C. — East Antarctica’s Denman Glacier has retreated 5 kilometers, nearly 3 miles, in the past 22 years, and researchers at the University of California, Irvine and NASA’s Jet Propulsion Laboratory are concerned that the shape of the ground surface beneath the ice sheet could make it even more susceptible to climate-driven collapse.

If fully thawed, the ice in Denman would cause sea levels worldwide

  • What goes in is not what comes out with a spatio-temporally modulated metasurface reflector

Researchers at Los Alamos National Laboratory are reinventing the mirror, at least for microwaves, potentially replacing the familiar 3-D dishes and microwave horns we see on rooftops and cell towers with flat panels that are compact, versatile, and better adapted for modern communication technologies. 

“Our new reflectors offer lightweight, low-profile alternatives to conventional antennas.

AGU News:

WASHINGTON, D.C. — During the exceptionally warm Arctic summer of 2019, Greenland lost 600 billion tons of ice, enough to raise global sea levels by 2.2 millimeters in two months, according to new research.

On the opposite pole, Antarctica continued to lose mass in the Amundsen Sea Embayment and Antarctic Peninsula but saw some relief in the form of increased snowfall in Queen Maud Land, in the eastern part of the continent.
