    Real-time observation of a metal complex-driven reaction intermediate using a porous protein crystal and serial femtosecond crystallography

    Determining short-lived intermediate structures in chemical reactions is challenging. Although ultrafast spectroscopic methods can detect the formation of transient intermediates, real-space structures cannot ...

    Oxygen-evolving photosystem II structures during S1–S2–S3 transitions

    Photosystem II (PSII) catalyses the oxidation of water through a four-step cycle of Si states (i = 0–4) at the Mn4CaO5 cluster13, during which an extra oxygen (O6) is incorporated at the S3 state to form a possi...

    Case and number suppletion in pronouns

    Suppletion for case and number in pronominal paradigms shows robust patterns across a large, cross-linguistic survey. These patterns are largely, but not entirely, parallel to patterns described in Bobaljik (2012

    A Much Worse Accident That Almost Happened in Fukushima: A Fire in a Dense-Packed Spent-Fuel Pool

    The previous chapter discussed the nightmare caused by the continuation of reprocessing despite the failure of the fast-breeder dream: accumulation of plutonium that could make tens of thousands of bombs.

    Deep Disposal of Spent Fuel Without Reprocessing

    With no need for startup plutonium for thousands of plutonium breeder reactors and with plutonium recycle in light-water reactors (LWRs) not economic, reprocessing and breeder advocates now argue that separati...

    Continuation of Plutonium Separation Without Breeder Reactors

    Because of their high costs and technical problems, liquid-sodium-cooled fast-neutron breeder reactors (FBRs) did not come into widespread use as power reactors. The US Atomic Energy Commission’s vision of a p...

    Early Dry-Cask Storage: A Safer Alternative to Dense-Packed Pools and Reprocessing

    Canceled and delayed plans for reprocessing, and delays in identifying central-storage and burial sites for spent fuel have resulted in nuclear utilities in a number of countries dense-racking their spent-fuel...
