Face masks effectively limit the probability of SARS-CoV-2 transmission

Posted by in categories: biotech/medical, particle physics

Do we need to revisit this? đŸ€”


Airborne transmission by droplets and aerosols is important for the spread of viruses. Face masks are a well-established preventive measure, but their effectiveness for mitigating SARS-CoV-2 transmission is still under debate. We show that variations in mask efficacy can be explained by different regimes of virus abundance and related to population-average infection probability and reproduction number. For SARS-CoV-2, the viral load of infectious individuals can vary by orders of magnitude. We find that most environments and contacts are under conditions of low virus abundance (virus-limited) where surgical masks are effective at preventing virus spread. More advanced masks and other protective equipment are required in potentially virus-rich indoor environments including medical centers and hospitals. Masks are particularly effective in combination with other preventive measures like ventilation and distancing.

Airborne transmission is one of the main pathways for the transmission of respiratory viruses, including the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (1). Wearing face masks has been widely advocated to mitigate transmission. Masks are thought to protect people in two ways: source control reducing the emission and spread of respiratory viruses through airborne droplets and aerosols, and wearer protection reducing the inhalation of airborne respiratory viruses.

World’s first supercapacitor-hybrid electric motorcycle will get a chance to prove itself

Posted by in categories: energy, sustainability, transportation

Audacious French company Nawa showed off a concept bike in 2019, claiming its supercapacitor-hybrid battery pack could massively boost power and urban range for electric motorcycles. Now, it seems we’ll get a chance to see if the numbers stack up.

We’ve been following Nawa since 2018, when we first spoke to these guys about the potential benefits of using powerful ultracapacitors alongside energy-dense lithium batteries to extend the range and boost the peak power of electric vehicles.

Aubrey de Grey: Breakthroughs in Longevity & The Anti-Aging Revolution

Posted by in categories: biotech/medical, life extension, wearables

Famed longevity pioneer Aubrey de Grey, Chief Science Officer of SENS Research Foundation, joins Geoffrey Woo, Founder and Chairman of Health Via Modern Nutrition Inc., for an enlightening conversation about advances in longevity, the investments and technologies that extend life, and the challenges and opportunities of a world in which people live longer. He walks us through his damage repair therapies with a focus on rejuvenation, prevention, and wearable technologies. Filmed on May 17, 2021. To continue the discussion with fellow Real Vision members on this interview, click here to visit the Exchange: https://rvtv.io/2T7nqZL

Key Learnings: Longevity escape velocity, which is a term de Grey coined, is the idea in which life expectancy is extended longer than the time that is passing, and he estimates a 50% chance that aging could be brought under medical control in as little as 15 years’ time.

U.S. has almost 500,000 job openings in cybersecurity

Posted by in categories: business, cybercrime/malcode, government

The need for more web watchmen spans from private businesses to government agencies, experts say, and most of the job openings are in California, Florida, Texas and Virginia. That means for anyone looking to switch careers and considering a job in cybersecurity, there’s no greater time than now to find work, the job trackers said.

“You don’t have to be a graduate of MIT to work in cybersecurity,” said Tim Herbert, executive vice president for research at CompTIA. “It just requires someone who has the proper training, proper certification and is certainly committed to the work.”

Infectious-disease scientists at Canada’s high-security lab collaborated with China

Posted by in categories: biotech/medical, military

Scientists working at Canada’s highest-security infectious-disease laboratory have been collaborating with Chinese military researchers to study and conduct experiments on deadly pathogens.

Seven scientists in the special pathogens unit at the National Microbiology Laboratory (NML) in Winnipeg and Chinese military researchers have conducted experiments and co-authored six studies on infectious diseases such as Ebola, Lassa fever and Rift Valley fever. The publication dates of the studies range from early 2016 to early 2020.

The Globe and Mail has also learned that one of the Chinese researchers, Feihu Yan, from the People’s Liberation Army’s (PLA) Academy of Military Medical Sciences, worked for a period of time at the Winnipeg lab, a Level 4 facility equipped to handle some of the world’s deadliest diseases. This researcher is credited as a co-author on all six of the papers. However, on two of them, he is listed as being affiliated with both the Winnipeg lab and the military medical academy.
