A novel coronavirus that first appeared in Wuhan, China, in December continues to sicken tens of thousands of people around the world – and scientists are working round the clock to better understand the virus, contain the outbreak, and treat the disease.

In the weeks since the outbreak, the disease has been named COVID-19 by the World Health Organization. (The virus itself has been named SARS-CoV-2 by the International Committee on Taxonomy of Viruses).

UC San Francisco infectious disease expert Charles Chiu, MD, PhD, has been following the disease since its outbreak and provided the latest updates on what science has revealed about how the coronavirus is transmitted, what happens to someone who’s infected, and why a single diagnostic test may not be enough.

“It’s going to disappear. One day it’s like a miracle, it will disappear,” said Trump.

Earth has acquired a second “mini-moon” about the size of a car, according to astronomers who spotted the object circling our planet.

The mass—roughly 1.9−3.5 meters (6−11 feet) in diameter—was observed by researchers Kacper Wierzchos and Teddy Pruyne at the NASA-funded Catalina Sky Survey in Arizona on the night of February 15.

“BIG NEWS. Earth has a new temporarily captured /Possible mini-moon called 2020 CD3,” likely to be a C-type asteroid, Wierzchos tweeted on Wednesday.

Two former top special operations officials say their job was too junior and the Pentagon isn’t taking information warfare seriously enough.

Despite shifting military budgets to better keep up with competitors, there’s one area where countries like China, Russia, and even Iran are proving nimble and frustrating for the Department of Defense: influence operations.

In this new age of information warfare, the military art of influence ops — otherwise sometimes called psychological ops, information ops, or most-recently, military information support ops — lacks the senior level leadership it deserves, say two former Pentagon officials who were in charge of special operations policies. According to them, the position they once held is too junior for the seriousness of the threat and mission, and influence ops is spread so wide, that nobody is sure who is really in charge.
