Heavy iron isotopes leaking from Earth’s core

by Becky Oskin, UC Davis, Phys.org

Earth’s molten core may be leaking iron, according to researchers who analyzed how iron behaves inside our planet.

The boundary between the liquid iron core and the rocky mantle is located some 1,800 miles (2,900 km) below Earth’s surface. At this transition, the temperature drops by more than a thousand degrees from the hotter core to the cooler mantle.

How Supercomputers Are Being Used To Win The Fight Against Coronavirus

by Jason Murdock, Newsweek

Scientific efforts to analyze, map and track the global COVID-19 outbreak are being aided by powerful supercomputers that scientists say may soon help to combat the infectious disease.

Computers capable of ingesting and processing vast amounts of raw data are coming together with the aim of better understanding the novel coronavirus that has now spread to at least 582,000 people in the U.S. and close to two million people globally, according to Johns Hopkins University statistics.

Watch Earth Zoom By As A Spacecraft Passes Us On Its Way (Eventually) To Mercury

by Phil Plait, Syfy Wire

BepiColombo is a joint European-Japanese mission currently on its way to the planet Mercury. It will map the surface and magnetosphere of the small world, and also make measurements that will characterize its interior, including the weirdly oversized core of the planet. It’s actually three spacecraft in one: a pair of orbiters that carry the scientific detectors, and a transfer vehicle that supports the orbiters on their way to Mercury and will place them into their orbits around it.

Law enforcement facing onslaught of coronavirus scams that could last for years

by Katelyn Polantz and Evan Perez, CNN

One of the most disturbing coronavirus scams Michigan Attorney General Dana Nessel has seen starts with a phone call.

The number looks like it’s coming from a health care or government official, who tells the person they’ve called that a loved one is in the hospital with coronavirus. The call recipient needs to give credit card information over the phone, now, to prepay the hospital bills.
