Scientists Use 100 Billion FPS Camera to Capture Lights Sonic Boom
When an object breaks the sound barrier—accelerates to the point where it’s moving faster than the speed of sound—it creates pressure waves that result in what is called a “sonic boom” and Mach cone. Now, scientists have managed to captured a similar phenomenon for light itself.
In case you’ve never seen it, this is what it looks like when a fighter jet breaks the sound barrier. That cone is called a Mach cone, signifying that the aircraft just exceeded Mach 1:
Scientists have known that light does something similar when moving from a medium where it is slowed down (like glass) into open air where it can move at full speed, but nobody had yet managed to capture this so-called “photonic Mach cone” on camera. Until Jinyang Liang and his team at Washington University in St. Louis, that is.
The breakthrough is not to be taken lightly. The speed of sound is approximately 340 meters per second; the speed of light, by comparison, is a blistering 3.0 x 10^8 meters per second. So how the heck do you capture something that fast on camera?

S. Carolina state rep. Chris Corley resigns; faces domestic violence charge
COLUMBIA, S.C. (AP) — A South Carolina state lawmaker accused of beating his wife bloody resigned on Tuesday rather than be expelled from the Statehouse. Rep. Chris Corley still faces a felony aggravated domestic violence charge that could put him in prison for up to 20 years.
House Speaker Jay Lucas read Corley's one-sentence resignation letter to his colleagues, which came as he was preparing to introduce legislation forcing Corley from his House seat.
"I am grateful that the House did not have to take such extraordinary measures," said Lucas, R-Hartsville.
While the state constitution gives the House authority to remove a member for disorderly conduct, the House hasn't expelled one of its own since the 1870s, according to the speaker's office.

Trump bans EPA employees from giving social media updates
Source: The Hill
President Trump has banned employees of the Environmental Protection Agency (EPA) from giving social media updates and speaking with reporters, according to The Associated Press.
The EPA ban comes amid other reports of agency staff being restricted from interacting the members of the Congress or the general public.
BuzzFeed reported Tuesday that the Department of Agriculture instituted a similar ban, telling its employees not to distribute information about research papers or to post on Twitter under the agency's name. A Tuesday report in the Huffington Post said agency employees under the Department of Health and Human Services were told not to speak to public officials.
White House spokesman Sean Spicer declined to comment on the reports, saying that he wasn't familiar yet with the specific reported bans. But Spicer said it was natural for a new administration to reconsider agency operations.

Note: This is different and more far-reaching than the earlier ban on discussing research findings.

USDA Scientists Have Been Put On Lockdown Under Trump
Source: Buzzfeed
The US Department of Agriculture has banned scientists and other employees in its main research division from publicly sharing everything from the summaries of scientific papers to USDA-branded tweets as it starts to adjust to life under the Trump administration, BuzzFeed News has learned.
According to an email sent Monday morning and obtained by BuzzFeed News, the department told staff — including some 2,000 scientists — at the agency’s main in-house research arm, the Agricultural Research Service (ARS), to stop communicating with the public about taxpayer-funded work.
“Starting immediately and until further notice, ARS will not release any public-facing documents,” Sharon Drumm, chief of staff for ARS, wrote in a department-wide email shared with BuzzFeed News.
