Researchers look at humidity as a weapon in the fight against airborne viruses

Posted by in category: biotech/medical

The ongoing fight against the COVID-19 pandemic could get a boost if Canadians paid more attention to the relative humidity levels in public and private spaces, according to a growing body of international research.

Doctors, scientists and engineers agree that sufficient indoor air moisture levels can have a powerful but little-understood effect on the transmission of airborne diseases. While the novel coronavirus that causes COVID-19 is currently treated as one that’s transmitted through droplet infection rather than the air, research on exactly how it passes between humans is still underway.

Most buildings, however, fall short of the recommended threshold of 40 to 60 per cent relative humidity, particularly in countries with colder, dryer climates such as Canada.

If Your Brain Were Cut in Half, Would You Still Be One Person?

Posted by in category: neuroscience

The implications of split-brain research have been widely debated. Scientists and philosophers have long argued over what is known as the mind-body quandary, the relationship between our mind and the physical brain. Some scientists saw the work of Sperry and others as supporting the notion that the brain operates almost entirely mechanically, and that consciousness, reasoning and free will have almost no effect. But Sperry strongly felt otherwise…

What this meant to Sperry was that free will, and responsibility, were no illusion. “It is possible to see today,” he believed, “an objective, explanatory model of brain function that neither contradicts nor degrades but rather affirms age-old humanist values, ideals, and meaning in human endeavor.”

It’s fair to say that the true significance of the split-brain experiments goes far beyond the significance of the lateralization of the brain; it also points to the immaterial nature of the mind.

The genetic architecture of the human cerebral cortex

Posted by in categories: biotech/medical, genetics, neuroscience

The human cerebral cortex is important for cognition, and it is of interest to see how genetic variants affect its structure. Grasby et al. combined genetic data with brain magnetic resonance imaging from more than 50,000 people to generate a genome-wide analysis of how human genetic variation influences human cortical surface area and thickness. From this analysis, they identified variants associated with cortical structure, some of which affect signaling and gene expression. They observed overlap between genetic loci affecting cortical structure, brain development, and neuropsychiatric disease, and the correlation between these phenotypes is of interest for further study.

Trial drug can significantly block early stages of COVID-19 in engineered human tissues

Posted by in category: biotech/medical

An international team led by University of British Columbia researcher Dr. Josef Penninger has found a trial drug that effectively blocks the cellular door SARS-CoV-2 uses to infect its hosts.

The findings, published today in Cell, hold promise as a treatment capable of stopping early infection of the novel coronavirus that, as of April 2, has affected more than 981,000 people and claimed the lives of 50,000 people worldwide.

3 Fun Space Games Play With Your Kids to combat isolation.

Space Related games to play with your kids to combat isolation.

So we are on month 3 of COVID19 here in Asia. We have had some time to figure out how to keep ourselves from going stir crazy. Playing some boardgames with the kids is a better alternative to youtube or xbox all day long.

I know that being stuck in side can be challenging. Going outside with your kids may not be a possibility if you live in a high density population area. So what do you do with your kids when they are stuck at home, getting stressed out or spending too much time online? Answer: Spend time with them.

Scholastic, the company that is known for educational fun books for kids, said that there many benefits for playing games as a family. If you bring out board games, the kid turn off the screen. You can have special time with your kids and allowing you to teach them about teamwork, patience, and how to win and lose gracefully. Board games can help benefit kids’ brains and language development.

  • Board games offer math skills like probability… but don’t tell them that.
  • They boost their language skills as they read cards and ask what words mean.
  • They sharpen your child’s focus by getting them interested in reading rules, looking at the play board and figuring out how to win.
  • They teach the value of teamwork. All for yourself doesn’t work very often in games. Kids learn that if they play dirty, other people adjust their strategy, and usually form alliances to counter a cutthroat player.
  • Strategy games are useful developing thinking skills. Working through problems, adjusting strategy to account for twists and turns is helpful.
  • Take your mind off things and easy anxiety. Looking at the news full time isn’t healthy. Especially kids don’t need to be exposed to all of the serious problems outside. Let them focus at home with you.
  • Show kids how to be a good loser (and winner). Winning is great. Playing in a way that everyone has fun is better. Kids will learn that is okay to fail in a game, because they can always play again and do better next time.
  • Unplug. Unplug. Unplug. To much screen time isn’t good for anyone. Let the eyes have a rest and let your and your kids brain unwind.
  • Set an example. Put down the phone and have a conversation with your kids. They will talk with you so much more when playing a game.

Here are a few games that we played during our first 3 months of being at home.

New measurements reveal evidence of elusive particles in a newly-discovered superconductor

Posted by in categories: particle physics, quantum physics

Particle chasing—it’s a game that so many physicists play. Sometimes the hunt takes place inside large supercolliders, where spectacular collisions are necessary to find hidden particles and new physics. For physicists studying solids, the game occurs in a much different environment and the sought-after particles don’t come from furious collisions. Instead, particle-like entities, called quasiparticles, emerge from complicated electronic interactions that happen deep within a material. Sometimes the quasiparticles are easy to probe, but others are more difficult to spot, lurking just out of reach.

New measurements show evidence for the presence of exotic Majorana particles on the surface of an unconventional superconductor, Uranium ditelluride. Graphic provided by Dr. E. Edwards, Managing Director of Illinois Quantum Information Science and Technology Center (IQUIST).

Now a team of researchers at the University of Illinois, led by physicist Vidya Madhavan, in collaboration with researchers from the National Institute of Standards and Technology, the University of Maryland, Boston College, and ETH Zurich, have used high-resolution microscopy tools to peer at the inner-workings of an unusual type of superconductor, uranium ditelluride (UTe2). Their measurements reveal strong evidence that this material may be a natural home to an exotic quasiparticle that’s been hiding from physicists for decades. The study is published in the March 26 issue of Nature.

Anti-Parasitic Drug Kills Coronavirus Cell Cultures in 48 Hours

Posted by in category: biotech/medical

“As the virologist who was part of the team who were first to isolate and share SARS-COV2 outside of China in January 2020, I am excited about the prospect of Ivermectin being used as a potential drug against COVID-19,” Leon Caly, senior medical scientist at the Victorian Infectious Diseases Reference Laboratory (VIDRL) at the Doherty Institute, said.

A vaccine for COVID-19 is likely still at least a year out, despite research teams across the world fast tracking work on potential vaccines. But that doesn’t mean we’re doomed.

“In times when we’re having a global pandemic and there isn’t an approved treatment, if we had a compound that was already available around the world then that might help people sooner,” Wagstaff said in the statement. “Realistically it’s going to be a while before a vaccine is broadly available.”

The next launch to the Space Station is planned for April 9th and is only a few days away. Preparations for the launch have been complicated with illness and coronavirus complications. AS OF NOW, the launch is still on track to rocket American astronaut Chris Cassidy and his two Russian cosmonauts Anatoly Ivanishin and Ivan Vagner. Originally, Ivanishin and Vagner were backup for expedition 63. Due to a temporary health condition, Ivanishin and Ivan Vagner were moved forward onto the prime crew. Because of delays in the US Commercial Crew Program, the crew on the ISS may be lower that normal.

Boeing and SpaceX delays put ISS operations at Risk

Since delays to the US Commercial Crew Program might leave Cassidy as the only crew member on the USOS for an extended period of time, Anatoli Ivanishin has been training on US EMU spacesuits. Cassidy has completed multiple EVAs in the past, including an unscheduled EVA. In the unlikely event that an unscheduled EVA is required before additional USOS crew members arrive on the station, then Ivanishin can support Cassidy. Should Ivanishin participate in EVA in the EMU he would be the first Russian cosmonaut to use an EMU since 2007 where Yuri Malenchenko performed the EVA with NASA Astronaut Peggy Whitson. Vagner has been to training on operation the USOS Robotic Arm (Canadarm 2) should there be a need to robotically support any EVA carried out by Cassidy and Ivanishin.

The three astronauts are scheduled to be in space until October 2020 by which time a SpaceX Crew Dragon should be able to rotate a new crew onto the ISS.

During expedition 63, NASA and SpaceX hope to accomplish the first humans launched to the ISS from American soil since the retirement of the space shuttle in 2011. SpaceX’s Crew Dragon Demo-2 mission is a flight test with crew. NASA astronauts Bob Behnken and Doug Hurley will take the Crew Dragon for a “Test drive” on the Demo-2 mission. NASA hopes to certify all of the systems operational for future crewed missions to the International Space Station.

FBI warns white supremacists encouraging members to spread coronavirus to law enforcement, Jews: report

Posted by in categories: biotech/medical, business, law enforcement

The Federal Bureau of Investigation’s New York office recently sent out an alert to local authorities warning of extremist groups it said are encouraging their members to spread the novel coronavirus to police and Jewish people, ABC News reported.

According to the news agency, the alert, which was reportedly issued on Thursday, said that “members of extremist groups are encouraging one another to spread the virus, if contracted, through bodily fluids and personal interactions.”

The alert reportedly warned that the racist groups were urging their members to go to places where Jewish people “may be congregated, to include markets, political offices, businesses and places of worship.”
