The fact that a particular nuclear weapon has (or does not have) a “dial-a-yield capability” enabling the selection of a desired explosive yield was declassified earlier this year, in a joint decision of the Department of Defense and the Department of Energy.
Last year, the Department of Energy also declassified the thickness of the “getter nickel plating” used in tritium production. (A “getter” here means the reactive material that sustains a vacuum by capturing gas atoms.)
These and several other recent DOE declassification decisions were recorded in memoranda that were released last week under the Freedom of Information Act. Copies are available, along with the records of prior DOE declassification actions, here.
Science funding agencies are biased against risk, making transformative research difficult to fund. Forecast-based approaches to grantmaking could improve funding outcomes for high-risk, high-reward research.
Establishing an NIH Office of Infection-Associated Chronic Illness Research can guard against the long-term effects of Covid and lead to novel breakthroughs across many less understood diseases.
A military depot in central Belarus has recently been upgraded with additional security perimeters and an access point that indicate it could be intended for housing Russian nuclear warheads for Belarus’ Russia-supplied Iskander missile launchers.
With a PhD in materials science, a postdoc position at the National Institute of Standards and Technology, and a stint as a AAAS Fellow, Dr. Shawn Chen has had a range of roles in the research community.
