Russian supercomputer Employed to Develop COVID-19 Treatment
MOSCOW & OTTAWA, Ontario — The Bioanalytical and Molecular Interaction Laboratory lead by Professor Maxim Berezovski at the University of Ottawa has joined an international science group – from Russia, Finland and Italy – which got high priority access to Russian RSC Tornado supercomputer for studying methods to fight against the COVID-19 coronavirus infection.
The multi-national research team uses a recently upgraded cluster system based on 2nd Generation Intel® Xeon® Scalable processors, which has been deployed by RSC Group, the leading Russian solution provider for high-performance computing.
The international project aims to develop medicine for diagnostics and therapy against the coronavirus contagious disease that became the cause of the global pandemic. Finding treatments to prevent and mitigate the negative impact of COVID-19 is the highest priority in the worldwide scientific community now. The international and multidisciplinary project takes advantages of the latest advances in experimental physics, chemistry, and biology to investigate the life cycle of the virus and to target specifically its specific proteins. Sophisticated simulation methods require supercomputing power to study all details of the interaction between the Spike-protein on coronavirus surface and the human protein ACE2 which is known to be the entry point for SARS and SARS-2 coronaviruses. It will help to complete all research stages within a limited amount of time.
“Rapid global spread of COVID-19 coronavirus infection pandemic has shown that there are no clear global emergency response plans against threats to humankind caused by new viruses. One of the obvious shortcomings is the lack of technologies for the quick development of medicines for diagnostics and therapy. We all have different competencies, knowledge, skills and resources. Our geographically distributed team includes virologists, biologists, chemists, mathematicians and physical scientists. The international cooperation is extremely important to achieve quick progress and rapidly react to the ever-changing situation with global coronavirus pandemic. We hope that our research will actually help to fight the spread of such infections,” explains Anna Kichkailo, Head of Laboratory for Digital Controlled Drugs and Theranostics at the Krasnoyarsk Federal Science Center of Russian Academy of Sciences.
The international team consists of:
- Laboratory for Digital Controlled Drugs and Theranostics and Laboratory of Physics of Magnetic Phenomena, Kirensky Institute of Physics at the Federal Science Center, Siberian Branch of Russian Academy of Sciences (KIP FSC SB RAS, Krasnoyarsk, Russia),
- Laboratory for Biomolecular and Medical Technology, V.F. Voyno-Yasenetsky Krasnoyarsk State Medical University (KSMU, Krasnoyarsk, Russia) – project coordinator,

'Canary in the coal mine': Greenland ice has shrunk beyond return, study finds – Reuters Canada
(Reuters) – Greenland’s ice sheet may have shrunk past the point of return, with the ice likely to melt away no matter how quickly the world reduces climate-warming emissions, new research suggests.

Scientists studied data on 234 glaciers across the Arctic territory spanning 34 years through 2018 and found that annual snowfall was no longer enough to replenish glaciers of the snow and ice being lost to summertime melting.
That melting is already causing global seas to rise about a millimeter on average per year. If all of Greenland’s ice goes, the water released would push sea levels up by an average of 6 meters — enough to swamp many coastal cities around the world. This process, however, would take decades.
“Greenland is going to be the canary in the coal mine, and the canary is already pretty much dead at this point,” said glaciologist Ian Howat at Ohio State University. He and his colleagues published the study Thursday in the Nature Communications Earth & Environment journal.
The Arctic has been warming at least twice as fast as the rest of the world for the last 30 years, an observation referred to as Arctic amplification. The polar sea ice hit its lowest extent for July in 40 years.
The Arctic thaw has brought more water to the region, opening up routes for shipping traffic, as well as increased interest in extracting fossil fuels and other natural resources.
Greenland is strategically important for the U.S. military and its ballistic missile early warning system, as the shortest route from Europe to North America goes via the Arctic island.
Last year, President Donald Trump offered to buy Greenland, an autonomous Danish territory. But Denmark, a U.S. ally, rebuffed the offer. Then last month, the U.S. reopened a consulate in the territory’s capital of Nuuk, and Denmark reportedly said last week it was appointing an intermediary between Nuuk and Copenhagen some 3,500 kilometers away.
Scientists, however, have long worried about Greenland’s fate, given the amount of water locked into the ice.
The new study suggests the territory’s ice sheet will now gain mass only once every 100 years — a grim indicator of how difficult it is to re-grow glaciers once they hemorrhage ice.
In studying satellite images of the glaciers, the researchers noted that the glaciers had a 50% chance of regaining mass before 2000, with the odds declining since.
“We are still draining more ice now than what was gained through snow accumulation in ‘good’ years,” said lead author Michalea King, a glaciologist at Ohio State University.
The sobering findings should spur governments to prepare for sea-level rise, King said.
“Things that happen in the polar regions don’t stay in the polar region,” she said.
Still, the world can still bring down emissions to slow climate change, scientists said. Even if Greenland can’t regain the icy bulk that covered its 2 million square kilometers, containing the global temperature rise can slow the rate of ice loss.
“When we think about climate action, we’re not talking about building back the Greenland ice sheet,” said Twila Moon, a glaciologist at the National Snow and Ice Data Center who was not involved in the study. “We’re talking about how quickly rapid sea-level rise comes to our communities, our infrastructure, our homes, our military bases.”

Science News Roundup: British fossil hunters find bones of new dinosaur species, cousin to T.Rex; 'Secret' life of sharks and more – Devdiscourse
Following is a summary of current science news briefs.
UC San Diego research lab to make environmentally friendly flip flops from algae
Researchers at the University of California, San Diego hope to make future beach visits both environmentally and fashion-friendly, with a new formula for biodegradable flip flops. Mike Burkart, professor of chemistry and biochemistry at the public research university in San Diego, California, has developed a polymer from algae, which decomposes naturally.
British fossil hunters find bones of new dinosaur species, cousin to T.Rex
Four bones found on a beach on the Isle of Wight, off England’s south coast, belong to a new species of theropod dinosaur, the group that includes Tyrannosaurus rex, researchers at the University of Southampton said on Wednesday. The new dinosaur, which has been named Vectaerovenator inopinatus, lived in the Cretaceous period 115 million years ago and was estimated to have been up to four metres long, the palaeontologists said.
Mystery of the dimming of massive star Betelgeuse explained
Astronomers have determined the cause of the dramatic dimming observed last year and earlier this year of one of the brightest stars in the night sky, a colossus called Betelgeuse that appears to be on its way toward a violent death. Based on Hubble Space Telescope observations, scientists said they believe Betelgeuse ejected a huge hot, dense cloud of material into space that cooled to form dust, shielding the star’s light and making it appear dimmer from the perspective of viewers on Earth.
‘Secret’ life of sharks: Study reveals their surprising social networks
Sharks have more complex social lives than previously known, as shown by a study finding that gray reef sharks in the Pacific Ocean cultivate surprising social networks with one another and develop bonds that can endure for years. The research focused on the social behavior of 41 reef sharks around the Palmyra Atoll, about 1,000 miles (1,600 km) southwest of Hawaii, using acoustic transmitters to track them and camera tags to gain greater clarity into their interactions.
Chemical signal for locust swarming identified in step toward curbing plagues
Scientists have identified a chemical compound released by locusts that causes them to swarm, opening the door to possible new ways to prevent these insects from devouring crops vital to human sustenance as they have for millennia. Researchers said on Wednesday they identified the pheromone – a chemical produced by an animal that affects the behavior of others of its own species – in the world’s most widespread locust species, the migratory locust, or Locusta migratoria.
Perseid Meteor Shower is Expected to Peak on August 11 and 12, Here’s How You Can Watch This Astrono … – Gizmo Posts 24
Though 2020 hasn’t been off the best of starts, we’ve still had a thing or two to cherish in these past few months. Apart from the pandemic, 2020 has been a year of several astronomical events. Right from January 2020, we have witnessed several major as well as minor astronomy events directly from our terrace or balcony. And after the last meteor shower in July 2020, it looks like we have another meteor shower to look for in August 2020.
It’s August, and its time for the best meteor showers of the year- the Perseid. The Perseid meteor is deemed as the best meteor shower to be observed. This meteor shower is caused by the comet ‘Swift-Tuttle,’ which was discovered in 1862. The Perseid meteor shower is famous for producing a large number of bright meteors. Actually, this meteor shower runs from July 17 to August 24 every year. However, the maximum show of Perseid Meteors occurs on 11th, 12th, and 13th August and is visible from both hemispheres.
Perseid Meteor Shower is Expected to Peak on August 11 and 12, Here’s How You Can Watch This Astronomy Event!
Though the Perseid meteor shower is visible from both hemispheres, it has the best view from the Northern hemisphere. The Perseid meteor shower tends to lose its intensity while being viewed from the Southern Hemisphere. One can see up to 100 meteors in an hour during the Perseid Meteor Shower.
The moon phase of 41.9% could interfere in the view. However, it is still a bright enough meteor shower allowing one to see up to 60 meteors in an hour. The Perseid Meteor shower will be best viewed from a dark location after midnight. Meteors will radiate from the constellation Perseus but can appear anywhere in the sky.
