Date Time Los Alamos study hopes to characterize and optimize ventilator treatment for Covid-19 LOS ALAMOS, N.M., Dec. 21, 2020—Cross-disciplinary scientists and engineers at Los Alamos National Laboratory are working to learn how Intrapulmonary Percussive Ventilation (IPV) helps clear mucus from blocking the airways of the human lung, a common reaction to the Covid-19 virus.   Researchers, using some of the same modeling and experimental techniques from the Laboratory’s nuclear weapons mission, are working to discover the underlying science and engineering principles behind this process...

Nuclear power and right now, i think iran's moving forward and the rest of the world is basically not doing anything that will change their behavior. >> now, what about the s.t.a.r.t. treaty? you said you have concerns about it. one of the things you said is that you're not sure about the weapons modernization. secretary gates believes there is adequate money for modernization and testing with the national labs. you know the defense appropriation better than anyone, so what doubts do you have about the ability of our nuclear stockpile to be kept you want to date as you look at this treaty? >> ...
