The last group most of the world wants to hear from right now is a lab in Wuhan, but if their microwave air plasma thruster is more real than their claims of having a certified BSL-2 lab studying coronavirus, there could be a great deal of interest in the future. 

Like solids, gases, and liquids, plasma is fourth state of matter found naturally in places like the sun's surface and Earth's lightning. The Institute of Technological Sciences at Wuhan University
say they have created a plasma jet by compressing air into high pressures and using a microwave to ionize the pressurized air stream.

Though slavery is still invoked in the United States of America, it is ironically because it was relatively rare compared to the rest of the continent. Only 4 percent of African slaves brought by Europeans and other Africans were brought to what is now the U.S, and importation was banned by President Thomas Jefferson in 1808. The remaining 96 percent went to Latin America and there is no benefit to invoking slavery when so many have not only slaves as ancestors, but also the colonizers who brought them.

Bringing in a huge population of slaves left behind a science story, and that story is filled out a little by three individuals found within a mass burial site from the 16th century at San José de los Naturales Royal Hospital in Mexico City.

Collective layoffs of large groups of workers have been common during the Coronavirus Pandemic of 2020.

A new paper might inform possible impacts because it analyzed 556 collective layoffs announced between December 2018 and November 2019 across different industries that involved more than 250,000 employees. They wanted to see what collective layoff decisions had on the firms that initiated them.

The termination of employment, particularly of large numbers of people, typically evokes negative connotations. While the effect on individuals is obvious they found that layoff announcements have negative effects on companies.

If you are an artist, you will need a much different bionic arm than a soldier and a new waypoint on the road to interchangeable bionics has been developed. 

In July 2019, the Clinical Laboratory for Bionic Limb Reconstruction at MedUni Vienna's Department of Surgery implanted sensors in three male patients following nerve transfers, to transmit biosignals for wireless control of bionic prostheses. 

The 5th century Mözs-Icsei dülő cemetery near Szekszárd in the area known as Pannonia dates back to the late Roman period. 

Remains reveal the demographic makeup during the beginnings of Europe's Migration Period, when the Huns invaded Central Europe and the Romans retreated from modern-day Western Hungary as the empire collapsed in the face of barbarian hordes.

When it comes to COVID-19 deaths, the elderly and those with certain pre-existing conditions are at greater risk, just like they are in any disease that can cause respiratory distress.

Yet demographers are beginning to break down those numbers to highlight disparities in outcomes. A new paper finds that even though men and women are equally likely to contract the virus, men are significantly more likely to suffer severe effects and die. 

What might explain it? Co-morbidities are certainly a factor, though deaths in people of color are higher than in Caucasian-Americans and co-morbidities are dismissed in those because it sounds too much like laying blame.
