New vulnerable sites identified on surface of COVID spike protein that ‘could help future vaccine development’

Technology

Scientists have discovered new vulnerable sites on the surface of the COVID-19 spike protein for antibodies which could help in the development of vaccines.Coronavirus is surrounded by spike proteins that it uses to enter and infect human cells. COVID vaccines work by teaching the immune system to make antibodies to the spike protein. Researchers from the Max Planck Institute of Biophysics in Frankfurt, Germany, have developed a detailed model of the spike protein to identify potential target sites on its surface for the antibodies.They said previous models have not shown the flexibility of the spike protein or the movements of the protective glycans - which they describe as chains of sugar molecules - that coat it. ...

Sun’s surface seen in remarkable new detail

Science

Media playback is unsupported on your device Behold the Sun's convulsing surface at a level of detail never seen before!The Daniel K Inouye Solar Telescope on Hawaii has released pictures that show features as small as 30km across.This is remarkable when set against the scale of our star, which has a diameter of about 1.4 million km and is 149 million km from Earth.The cell-like structures are roughly the size of the US state of Texas. They are convecting masses of hot, excited gas, or plasma.The bright centres are where this solar material is rising; the surrounding dark lanes are where plasma is cooling and sinking. Cheops telescope launches to study far-off worlds Solar Orbiter ready to take on audacious mission DKIST is a brand new facili...

Navy requests proposals for Large Unmanned Surface Vehicle

Business

Aug. 15 (UPI) -- The U.S. Navy continues to build up its unmanned vehicle programs, issuing a request for proposals for the corvette-sized Large Unmanned Surface Vehicle. The Naval Sea Systems Command on Wednesday issued the RFP, with plans to award multiple conceptual designs for the LUSV, one of three new types of unmanned vehicle the branch is looking to develop. The RFP, first reported by USNI News, starts a move from the two-hull Ghost Fleet into an actual ship-building program. Interest in the program is strong, as an industry day earlier this year attracted about 80 companies that are considering jumping into the program. NSSC said in the request that the LUSV will be a high-endurance, reconfigurable ship to augment the Navy's surface force, and take on a variety of warfare operat...

Navy seeks proposals for unmanned surface vessel

Business

July 17 (UPI) -- A U.S. Navy request for proposals calls for a new class of unmanned surface vessels. While the Navy floated performance specifications in February for a fleet of "medium unmanned surface vehicles," the request was officially announced Tuesday. It seeks developers for a craft of up to 164 feet long, to function as a sensor and communications relay in part of a family of unmanned surface systems under development. The craft would be able to carry a payload equivalent to a 40-foot shipping container, operate on its own for at least 60 days before requiring a return to port, and be capable of refueling at sea. The Navy plans to award a contract for a single MUSV prototype in the first quarter of fiscal year 2020, a statement from the U.S. Naval Sea Systems Command said. It a...
