When researchers reported last month that the novel coronavirus causing the COVID-19 pandemic survives for days on glass and stainless steel but dies within hours after landing on copper, the only thing that surprised Bill Keevil was that the pathogen lasted so long on copper.
Global stocks have lost at least $6 trillion in market value since Jan. 20 when the coronavirus outbreak first started becoming a concern for investors. The decline accelerated this week as the spread of cases outside of China picked up pace, sparking a worldwide sell-off that led to six straight sessions of losses for stocks through Thursday. Infections in South Korea have skyrocketed to more than 2,000 from less than 100 a week ago, while new cases in Italy and Iran have also seen a sharp up-t.
See mushrooms are not of this earth o.o
Japanese researchers are closing in on understanding why electrical storms have a positive influence on the growth of some fungi. In a series of experiments, Koichi Takaki at Iwate University and colleagues showed that artificial lightning strikes do not have to directly strike shiitake mushroom cultivation beds to promote growth. Now they are developing technology to use electric stimulation in the production of the mushrooms, which are popular in many east Asian cuisines.
Bizarre as it may seem, atmospheric electricity has long been known to boost the growth of living things, including plants, insects and rats. In 1775, the priest and physicist Giovanni Battista Beccaria of the University of Turin reported, “it appears manifest that nature makes extensive use of atmospheric electricity for promoting vegetation”.

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.
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.
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.
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.
