“Cannabis extracts are showing potential in making people more resistant to the novel coronavirus, says an Alberta researcher leading a study.

After sifting through 400 cannabis strains, researchers at the University of Lethbridge are concentrating on about a dozen that show promising results in ensuring less fertile ground for the potentially lethal virus to take root, said biological scientist Dr. Igor Kovalchuk.”

But the absence of clinical trials remains a barrier, and funding from an increasingly cash-strapped cannabis industry isn’t there to fuel that, said Kovalchuk.

A new oversight board will govern Facebook content in an attempt to decentralize its policing of user posts. But is it just cover for further censorship?

Researchers at ARCNL and Vrije Universiteit Amsterdam have developed a compact setup for fast, super-resolution microscopy through an ultrathin fiber. Using smart signal processing, they beat the theoretical limits of resolution and speed. Because the method does not require any special fluorescent labelling, it is promising for both medical applications and characterization of 3D structures in nanolithography. On May 7th, the results were published in Light: Science & Applications, a scientific journal in the Nature family.

“Imaging at the nanoscale is limited by the wavelength of the light that is used. There are ways to overcome this diffraction limit, but they typically require large microscopes and difficult processing procedures,” says Lyuba Amitonova. “These systems are unsuitable for imaging in deep layers of biological tissue or in other hard-to-reach places.”

Amitonova recently started a research group on Nanoscale Imaging and Metrology at ARCNL. She is also connected part-time to VU Amsterdam where she works on ultrathin fibers for endomicroscopy in the group of Johannes de Boer. Amitonova and de Boer have developed a way to overcome the diffraction limit in small systems to enable deep-tissue imaging with super-resolution.

The next-generation networks will provide major strides in latency, speed and localized access to AI.

The researchers linked two copies of a special kind of antibody produced by llamas to create a new antibody that binds tightly to a key protein on the coronavirus that causes COVID-19. This protein, called the spike protein, allows the virus to break into host cells. Initial tests indicate that the antibody blocks viruses that display this spike protein from infecting cells in culture.

“This is one of the first antibodies known to neutralize SARS-CoV-2,” said Jason McLellan, associate professor of molecular biosciences at UT Austin and co-senior author, referring to the virus that causes COVID-19.

The team is now preparing to conduct preclinical studies in animals such as hamsters or nonhuman primates, with the hopes of next testing in humans. The goal is to develop a treatment that would help people soon after infection with the virus.

NASA astronauts Bob Behnken and Doug Hurley completed their final training sessions in Houston this week before their scheduled May 27 liftoff on a SpaceX Dragon spacecraft from the Kennedy Space Center, the first launch of humans from the Florida spaceport since 2011.

The two veteran space fliers participated in their final full-up launch simulation Monday, strapping into a Dragon simulator at the Johnson Space Center in Houston and tying in with SpaceX and NASA teams at the Kennedy Space Center in Florida and at SpaceX headquarters in Hawthorne, California.

Behnken tweeted Thursday that the crew’s formal training activities were complete. The astronauts were expected to have a few days of off-duty time before preparing to travel from their home base in Houston to the Kennedy Space Center on May 20.

Two Chinese boys dropped dead within a week of one another while wearing face masks during gym class, according to a report.

The students, who were both 14, were each running laps for a physical examination test when they suddenly collapsed on the track, Australian outlet 7News reported.

One of the teens was only minutes into his gym class when he fell backward April 24 at Dancheng Caiyuan Middle School in Henan province, according to the outlet.

Pulmonologist Zhong Nanshan, known to have discovered the SARS virus in 2003, reported that the pathogen is three times more contagious than common influenza; however, he admits that its spread is likely to slow with the onset of summer.

BERLIN: The European Space Agency said Friday that human urine could one day become a useful ingredient in making concrete to build on the moon.

The agency said researchers in a recent study it sponsored found that urea, the main organic compound in urine, would make the mixture for a “lunar concrete” more malleable before it hardens into its sturdy final form.
