Projecting the transmission dynamics of SARS-CoV-2 through the postpandemic period

Posted by in categories: biotech/medical, surveillance

It is urgent to understand the future of severe acute respiratory syndrome–coronavirus 2 (SARS-CoV-2) transmission. We used estimates of seasonality, immunity, and cross-immunity for betacoronaviruses OC43 and HKU1 from time series data from the USA to inform a model of SARS-CoV-2 transmission. We projected that recurrent wintertime outbreaks of SARS-CoV-2 will probably occur after the initial, most severe pandemic wave. Absent other interventions, a key metric for the success of social distancing is whether critical care capacities are exceeded. To avoid this, prolonged or intermittent social distancing may be necessary into 2022. Additional interventions, including expanded critical care capacity and an effective therapeutic, would improve the success of intermittent distancing and hasten the acquisition of herd immunity. Longitudinal serological studies are urgently needed to determine the extent and duration of immunity to SARS-CoV-2. Even in the event of apparent elimination, SARS-CoV-2 surveillance should be maintained since a resurgence in contagion could be possible as late as 2024.

The ongoing severe acute respiratory syndrome–coronavirus 2 (SARS-CoV-2) pandemic has caused nearly 500,000 detected cases of coronavirus disease 2019 (COVID-19) illness and claimed over 20,000 lives worldwide as of 26 Mar 2020. Experience from China, Italy, and the United States demonstrates that COVID-19 can overwhelm even the healthcare capacities of well-resourced nations (2–4). With no pharmaceutical treatments available, interventions have focused on contact tracing, quarantine, and social distancing. The required intensity, duration, and urgency of these responses will depend both on how the initial pandemic wave unfolds and on the subsequent transmission dynamics of SARS-CoV-2. During the initial pandemic wave, many countries have adopted social distancing measures, and some, like China, are gradually lifting them after achieving adequate control of transmission.

Quantum Computing With Particles Of Light: A $215 Million Gamble

Posted by in categories: computing, mobile phones, particle physics, quantum physics

PsiQuantum is a little-known quantum computing startup, however it recently had no trouble raising almost a quarter of a billion dollars from Microsoft’s M12 venture fund and other investors. That is in addition to a whopping $230 million it received last year from a fund formed by Andy Rubin, developer of the Android operating system.

The company was founded in 2016 by British professor Jeremy O’Brien and three other academics, Terry Rudolph, Mark Thompson, and Pete Shadbolt. In just a few years, they have quietly grown the company from a few employees to a robust technical staff of more than 100.

Compared to today’s modest quantum computing capabilities, PsiQuantum’s elevator pitch for investors sounds like a line from a science fiction movie. O’Brien not only says he is going to build a fault-tolerant quantum computer with a staggering one million qubits, he also says he is going to do it within five years. O’Brien’s technology of choice for this claim is silicon photonics, which uses particles of light called photons to perform quantum calculations. Theoretically, photons behave as both waves and particles, but that’s a subject for another article. Quantum computing technologies in use today are primarily superconductors and trapped ion. However, there is plenty of research that shows photonics holds a lot of promise.

House-sized asteroid to fly close to Earth Wednesday

Posted by in category: space

An asteroid the size of a house will pass the Earth Wednesday, eventually reaching a distance closer to Earth than the moon, according to AccuWeather.

The newly discovered Asteroid 2020 GH2 will pass within the orbit of the moon, about 223,000 miles away. It’s between 43 and 70 feet wide.

NASA’s asteroid watch regularly monitors the sky to watch out for astronomical objects that may pose a danger to hitting Earth.

Watch the world’s most advanced F-15 make its maiden flight with a ‘Viking’ takeoff

Posted by in category: military

If you’re looking for a taste of what the Air Force’s first new F-15 fighter jet in nearly 20 years might look like, look no further than the first flight of the F-15QA.

Developed for the Qatar Emiri Air Force and billed as “the most advanced version of the jet ever manufactured,” Boeing announced on Tuesday that it had successfully completed the first flight of its F-15QA variant at Lambert International Airport in St. Louis, Missouri.

Possible Chinese Nuclear Testing Stirs U.S. Concern

Posted by in categories: energy, nuclear weapons

China might be secretly conducting nuclear tests with very low explosive power despite Beijing’s assertions that it is strictly adhering to an international accord banning all nuclear tests, according to a new arms-control report to be made public by the State Department.

The coming report doesn’t present proof that China is violating its promise to uphold the agreement, but it cites an array of activities that “raise concerns” that Beijing might not be complying with the “zero-yield” nuclear-weapons testing ban.

Hot qubits break one of the biggest constraints to practical quantum computers

Posted by in categories: business, computing, government, quantum physics

Most quantum computers being developed around the world will only work at fractions of a degree above absolute zero. That requires multi-million-dollar refrigeration and as soon as you plug them into conventional electronic circuits they’ll instantly overheat.

But now researchers led by Professor Andrew Dzurak at UNSW Sydney have addressed this problem.

“Our new results open a path from experimental devices to affordable quantum computers for real world business and government applications,” says Professor Dzurak.

Why simply waiting for herd immunity to covid-19 isn’t an option

Posted by in categories: biotech/medical, government, policy

The widespread perception that it was once official British policy to let the novel coronavirus spread until the population reached herd immunity is false; the government was just overly optimistic about how easy flattening the curve would be. But the idea has gained so much traction in some circles, fueled by speculation that we might already be much closer to it than we think, that it’s worth understanding why it’s not a viable policy according to the evidence to date.

The Coronavirus Can’t Stop America’s Nukes

Posted by in categories: biotech/medical, business, military, nuclear weapons

As the world fights against the COVID-19 pandemic, nuclear weapons have taken a backseat in most people’s minds. But for Global Strike Command (AFGSC)—the Air Force unit in control of two of the three legs of America’s nuclear triad—their mission remains top priority.

And it’s an unforgiving business. Nuclear deterrence requires extreme levels of readiness among pilots, maintenance crews, and security teams. Adversaries that don’t think the U.S. can respond with conventional bombing strikes or nukes could be emboldened to act aggressively.
