Moderna Inc. said the U.S. government has agreed to pay as much as $483 million for the company to develop and test its Covid-19 vaccine now in an initial clinical trial.
A key component of NASA’s X-59 Quiet SuperSonic Technology (QueSST) aircraft is undergoing vibration tests at the space agency’s Langley Research Center in Hampton, Virginia. The eXternal Vision System (XVS) is a special camera system that the pilot of the X-plane will use to see forward while the experimental supersonic craft is in flight.
When the X-59 takes to the skies in 2021, the pilot will be faced with a problem not often encountered since the Concorde fleet of supersonic passenger jetliners was retired. The X-59 is meant to test new technologies to build a new generation of supersonic commercial aircraft and, while it promises to overcome some of the drawbacks of Concorde, it will still share some of its difficulties.
One is that the ideal design of a long-range supersonic liner is essentially that of a needle-nosed dart. The annoying thing is that, though this shape may be fine from an aerodynamic point of view, it makes it extremely difficult for the pilot to see forward without a lot of complex mechanics, like Concorde’s droop nose and special sliding windscreen.
:oooo.
One of the defining features of Covid-19 is the excessive immune response that can occur in severe cases. This burst of immune overreaction, also called a cytokine storm, damages the lungs and can be fatal.
A team of MIT researchers has developed specialized proteins, similar in structure to antibodies, that they believe could soak up these excess cytokines.

How did matter gain the edge over antimatter in the early universe? Maybe, just maybe, neutrinos.

A Chicago hospital treating severe COVID19 patients with Gilead Sciences’ antiviral medicine remdesivir in a closely watched clinical trial is seeing rapid recoveries in fever and respiratory symptoms, with nearly all patients discharged in less than a week, STAT has learned.
Remdesivir was one of the first medicines identified as having the potential to impact SARS-CoV-2, the novel coronavirus that causes Covid-19, in lab tests. The entire world has been waiting for results from Gilead’s clinical trials, and positive results would likely lead to fast approvals by the Food and Drug Administration and other regulatory agencies. If safe and effective, it could become the first approved treatment against the disease.
The outcomes in patients at a Chicago hospital offer only a snapshot of remdesivir’s effectiveness, but are the first clinical data to surface to date.

We present a calculation of a neutrino decay scenario in the early Universe. The specific decay is ν_{2} \to ν_{1} + ϕ, where ϕis a boson. If there is a neutrino mass hierarchy, m_{ν_{e}} m_{ν_μ} m_{ν_τ}, we show that it is possible to generate stimulated decay and effects similar to atomic lasing without invoking new neutrinos, even starting from identical neutrino distributions. Under the right circumstances the decay can be to very low momentum boson states thereby producing something similar to a Bose condensate, with possible consequences for structure formation. Finally, we argue that this type of decay may also be important other places in early Universe physics.
Kebotix, which is developing a lab automation platform that leverages AI and robotics, has raised $11.5 million in venture capital.
AT&T is connecting IoT robots, in new partnerships with Xenex and Brain Corp., that aim to help hospitals and retail establishments like grocery stores keep facilities clean, kill germs and keep shelves stocked more efficiently.
Chris Penrose, SVP of Advanced Solutions at AT&T, told FierceWireless that the robots are riding on the carrier’s 4G LTE network, rather than narrowband IoT (NB-IoT) or LTE-M networks. That’s because of the large amounts of data they need to push, along with latency and speed requirements for these particular use cases.
