Science Glance
Superbugs, or enterococci bacteria, have been honing their defensive capabilities for at least 450 million years.
As a new survey of the evolution of antibiotic resistance revealed, the earliest relatives of modern superbugs -- microbes undeterred by antibiotics -- emerged prior to the arrival of the dinosaurs.
"By analyzing the genomes and behaviors of today's enterococci, we were able to rewind the clock back to their earliest existence and piece together a picture of how these organisms were shaped into what they are today," researcher Ashlee M. Earl, leader of the Bacterial Genomics Group at the Broad Institute, said in a news release. "Understanding how the environment in which microbes live leads to new properties could help us to predict how microbes will adapt to the use of antibiotics, antimicrobial hand soaps, disinfectants and other products intended to control their spread."
Antibiotic-resistant bacteria first emerged at least 450 million years ago
New device turns dirty air into energy
A team of Belgian scientists have developed a new device capable of generating power while cleaning polluted air.
The device, which must be exposed to sunlight to function, features two chambers separated by a single membrane. The air is cleaned on one side, while contaminants are converted into hydrogen gas on the other.
"This hydrogen gas can be stored and used later as fuel, as is already being done in some hydrogen buses, for example," Sammy Verbruggen, a professor at the University of Antwerp, said in a news release.
Philippine's Duterte: Sorry, I Can’t Promise WH Visit
“I cannot make any definite promise. I am supposed to go to Russia; I am supposed to go to Israel,” he said, according to Yahoo News.
Trump's invitation to Duterte, who has been accused of backing the vigilante execution of people involved in the drug trade and threatening journalists and political opponents, drew criticism from human rights groups. He invited the controversial leader to the White House without consulting the State Department or the National Security Council.
TVNL Comment: Trump did not bother to inform the State Department before issuing an invitation to this murderer who boasted of being willing to '...execute three million drug addicts."
Cassini radio signal from Saturn picked up after dive
The Cassini spacecraft is sending data back to Earth after diving in between Saturn's rings and cloudtops.
The probe executed the daredevil manoeuvre on Wednesday - the first of 22 plunges planned over the next five months - while out of radio contact. Nasa's 70m-wide Deep Space Network (DSN) antenna at Goldstone, California, managed to re-establish communications at 06:56 GMT (07:56 BST) on Thursday.
Astronaut Peggy Whitson Sets New NASA Record For Most Days In Space
Nearly 15 years after her first space launch, NASA astronaut Peggy Whitson has now spent more time off-planet than any other American, at more than 534 days. Whitson, 57, is a biochemist who has twice commanded the International Space Station.
"It is one of those rides that you hope never ends," Whitson tweeted last night. "I am so grateful for all those who helped me on each of my missions!"
Penguins hold their own Science March of the Penguins
In honor of Earth Day and the March for Science, the Monterey Bay Aquarium held it's own mini Science March with several of its African penguins.
The aquarium dubbed its livestream the "March of the Penguins for Science," and it included their African penguins taking an "enrichment walk" through the Kelp Forest gallery.
Onlookers held signs for the march.
One read: "Honk honk, bray bray, African penguins are here to stay."
Earth Day - April 22, 2017 Washington DC - Join us on the National Mall
This Earth Day, April 22, Earth Day Network and the March for Science are co-organizing a rally and teach-in on the National Mall in Washington, D.C. The day’s program will include speeches and trainings with scientists and civic organizers, musical performances, and a march through the streets of Washington, D.C. The crowd will gather at 8:00am, and the teach-in will begin at 09:00am.
This Earth Day, join the effort to defend the vital public service role science plays in our communities and our world.
Science serves all of us.
