Australia enlists particle accelerator in coronavirus fight

Published

on

Australian scientists are using the largest particle accelerator in the southern hemisphere to help fast-track the hunt for a vaccine against COVID-19, researchers said Tuesday.

The Australian Synchrotron in Melbourne uses intense X-rays emitted by electrons coursing through the accelerator to examine key proteins in the virus, programme director Andrew Peele told AFP.

Acting as a kind of microscope, the accelerator lets the researchers construct atomic-level 3-D maps of the proteins so they can develop drugs that bind to the virus, potentially preventing or treating the disease.

“We shine the light on the proteins and the light that scatters off them tells us where every atom in the (COVID-19)protein molecule is,” Peele said.

“You need to know what the protein looks like so you can design a drug to attach to it,” he added.

“It’s like designing a key for a lock, you need to know the dimensions of the keyhole.”

Researchers from around the world have sent the Melbourne team dozens of sample of proteins which they think might bind with the COVID-19 virus in a way that could minimise or protect from the disease, Peele said.

“Using our technology, within five minutes you can understand why a drug does or doesn’t work in attaching to a COVID-19 protein,” Peele said, likening the process to completing a jigsaw puzzle.

The government-funded project hopes its fast-tracking technology will shorten the normal development time for effective vaccines.

Scientists around the world are racing to develop vaccines and treatments for COVID-19, which has turned into a raging pandemic that has killed tens of thousands and infected more than 750,000 people across the planet.

WATCH: John Oliver exposes Trump’s lies about vote-by-mail — and the Fox News ‘cult’ claiming the election is already ‘rigged’

Published

on

"Last Week Tonight" host John Oliver's main story Sunday refuted President Donald Trump's latest crusade against vote-by-mail. Trump announced on Twitter that the more people who vote in an election, the more Republicans tend to lose. So, he wants fewer people to have access to the ballot in November, even if people are too scared to go out during the coronavirus crisis.

Oliver called out Missouri Gov. Mike Parson (R-MO), who outright told people not to vote if they were too afraid to vote in the local elections next week.

"Well, hold on there," Oliver interjected. "Voting is a right. It has to be easy to understand and accessible to anyone."

John Oliver rips Fox News’ Tucker Carlson for urging ‘order’ from people of color — but never demanding it of police

Published

on

John Oliver opened his Sunday show, shredding Fox News host Tucker Carlson for uring "order" among protesters, but refusing to urge "order" to police and "wannabe police" who can't stop killing people.

It's a lot, Oliver explained. "How these protests are a response to a legacy of police misconduct, both in Minneapolis and the nation at large and how that misconduct is, itself, built on a legacy of white supremacy that prioritizes the comfort of white Americans over the safety of people of color."

While some of it is complicated, Oliver conceded, most of it is "all too clear."

Cars set on fire blocks from White House as DC protests turn violent

Published

on

The Washington, D.C. protests turned violent as the city approached the 11 p.m. curfew the mayor instituted Sunday afternoon.

The policy of D.C. police is that when they are attacked, they advance forward. So, when fireworks were fired, the line of officers began pushing the protesters back further from the White House. Behind the line of police officers also stand a line of National Guard troops that President Donald Trump has demanded stand watch in the city.

Lights that normally shine on the White House have also been turned off, reporters revealed.
