The doctor added that the virus has “outsmarted all of us,” since he says it’s able to hide symptoms for up to 24 days — which contradicts current guidance that the incubation period is two weeks.

Chinese doctors sounding the alarm on the coronavirus say the illness could be even deadlier for patients who catch it again, according to a report.

The whistleblowing physicians working to fight the virus in Wuhan, the epicenter of the outbreak, revealed that medically cleared patients have been getting reinfected, the Taiwan News reported.

Chip maker Intel has been chosen to lead a new initiative led by the U.S. military’s research wing, DARPA, aimed at improving cyber-defenses against deception attacks on machine learning models.

Machine learning is a kind of artificial intelligence that allows systems to improve over time with new data and experiences. One of its most common use cases today is object recognition, such as taking a photo and describing what’s in it. That can help those with impaired vision to know what’s in a photo if they can’t see it, for example, but it also can be used by other computers, such as autonomous vehicles, to identify what’s on the road.

But deception attacks, although rare, can meddle with machine learning algorithms. Subtle changes to real-world objects can, in the case of a self-driving vehicle, have disastrous consequences.

The global race to make a vaccine and treatment for the Covid-19 coronavirus is well underway as the epicenter of the pandemic is now shifting toward the United States.

Many of the vaccine and drug development efforts are building on past efforts to deal with other viral outbreaks, including coronaviruses like MERS and SARS — which means researchers had a head start with Covid-19. In the US, a phase 1 clinical trial of a vaccine is already underway.

Since the original work on Bose–Einstein condensation^1,2, the use of quantum degenerate gases of atoms has enabled the quantum emulation of important systems in condensed matter and nuclear physics, as well as the study of many-body states that have no analogue in other fields of physics³. Ultracold molecules in the micro- and nanokelvin regimes are expected to bring powerful capabilities to quantum emulation⁴ and quantum computing⁵, owing to their rich internal degrees of freedom compared to atoms, and to facilitate precision measurement and the study of quantum chemistry⁶. Quantum gases of ultracold atoms can be created using collision-based cooling schemes such as evaporative cooling, but thermalization and collisional cooling have not yet been realized for ultracold molecules. Other techniques, such as the use of supersonic jets and cryogenic buffer gases, have reached temperatures limited to above 10 millikelvin^7,8. Here we show cooling of NaLi molecules to micro- and nanokelvin temperatures through collisions with ultracold Na atoms, with both molecules and atoms prepared in their stretched hyperfine spin states. We find a lower bound on the ratio of elastic to inelastic molecule–atom collisions that is greater than 50—large enough to support sustained collisional cooling. By employing two stages of evaporation, we increase the phase-space density of the molecules by a factor of 20, achieving temperatures as low as 220 nanokelvin. The favourable collisional properties of the Na–NaLi system could enable the creation of deeply quantum degenerate dipolar molecules and raises the possibility of using stretched spin states in the cooling of other molecules.

O.,o definitely odd still unknown the cause.

Wildlife groups in Greece say that thousands of swallows and other migratory birds have died in Greece in the last few weeks, unable to recover from the exhausting journey from Africa, made even worse this year due to the chilly weather conditions.

Scientists say that persistent strong northerly winds over the Mediterranean and the Aegean have exhausted the birds, who have been spotted in their thousands walking on streets instead of flying as they try to recover.

In what seems to be the automotive equivalent of a brazen act intended to show dominance, Elon Musk has announced on Twitter that Tesla will be releasing a “Plaid” version of the Cybertruck. Musk did not provide further details in his tweet, though there is little doubt that the feature will make the already daunting Tri-Motor pickup into something downright scary for its fossil fuel-powered rivals like the Ford F-150 Raptor.

Elon Musk’s Plaid Cybertruck revelation was shared on Twitter late Wednesday. While responding to Tesla owner-enthusiast and Third Row Podcast member Sofiaan Fraval, Musk stated that he would be driving a Plaid version of the all-electric pickup truck for personal use. This came as a pleasant surprise to the EV community, especially since this is the first time that such a version of the Cybertruck has been mentioned.

Elon Musk has mentioned in the past that the Tesla Cybertruck will have the handling and performance of a sports car, and this was highlighted during the vehicle’s unveiling event. Apart from showcasing its strength by having the hulking all-electric pickup pull a Ford F-150 like a rag doll, Tesla also featured the Cybertruck drag racing a Porsche 911, and crushing the iconic sports car in the process. These are bold demonstrations, and each was met with equal parts excitement and skepticism from the auto community.

CERN has established a task force to identify and support contributions from the Organization’s 18 000-strong global community to combatting the COVID-19 pandemic. Set up by the Director-General at the end of March, the CERN against COVID-19 task force has already received hundreds of messages suggesting ideas ranging from producing sanitizer gel to designing and building sophisticated medical equipment. The design of a novel ventilator, expected to be tested by healthcare experts in the coming weeks, is an example of deployment of CERN’s technology to the service of society in these troubled times. Details of the initiatives and projects supported will be published on the dedicated website cern.ch/against-covid-19, which will be regularly updated.

“CERN is a world leading laboratory in particle physics and in the related technologies. As such, it’s a hub of resources, including the World-wide LHC Computing Grid, WLCG, mechanical workshops, sophisticated design and prototyping facilities, advanced technologies and expertise ranging from science and engineering to industrialisation,” said Director-General Fabiola Gianotti. “We want to deploy our resources and competences to contribute to the fight against the COVID-19 pandemic.”

CERN’s overall approach is to ensure effective and well-coordinated action, drawing on CERN’s many competencies and advanced technologies and working closely with experts in healthcare, drug development, epidemiology and emergency response so as to maximise the impact of the Organization’s contributions. To this end, the Organization has established links with local hospitals and emergency services, and in the context of an agreement established in 2011, entered into dialogue with experts at the World Health Organization. Discussions are also underway with sister European scientific organisations, the European Molecular Biology Organization and the European Bioinformatics Institute.

Doctors are reaching for drugs that dampen the immune response — but these also undermine the body’s own fight against the coronavirus. Uncertainty is hampering doctors’ ability to choose treatments.

At the height of the epidemic in the city, Jinyintan was treating close to 500 coronavirus patients, he said. It currently still has 123 under observation, he said. A study published last month in the New England Journal of Medicine, based on a test in Chinese patients with severe COVID-19 at Jinyintan, said that Kaletra, also known as Aluvia, was not effective as a potential treatment.

Last month, Israel approved the licensing of a generic version of Kaletra to treat patients infected with the coronavirus.
