  摘要：The chemical composition of the interstellar medium and planetary atmospheres is constantly in flux as atoms and molecules collide and interact with high-energy particles such as electrons, protons, and photons. These transformative processes ultimately lead to the coalescence of molecules and eventually the birth of stars. Our understanding of these chemical ecosystems relies on models that synthesize data from gas-phase experiments, providing insights into reaction cross sections. This Revie...

  摘要：The energetic disorder induced by fluctuating liquid environments acts in opposition to the precise control required for coherence-based sensing. Overcoming fluctuations requires a protected quantum subspace that only weakly interacts with the local environment. We report a ytterbium complex that exhibited an ultranarrow absorption linewidth in solution at room temperature with a full width at half maximum of 0.625 milli-electron volts. Using spectral hole burning, we measured an even narrower...

  摘要：The short-term impact of famines on death and disease is well documented, but estimating their potential long-term impact is difficult. We used the setting of the man-made Ukrainian Holodomor famine of 1932-1933 to examine the relation between prenatal famine and adult type 2 diabetes mellitus (T2DM). This ecological study included 128,225 T2DM cases diagnosed from 2000 to 2008 among 10,186,016 male and female Ukrainians born from 1930 to 1938. Individuals who were born in the first half-year ...

  摘要：Ketamine has been found to have rapid and potent antidepressant activity. However, despite the ubiquitous brain expression of its molecular target, the N-methyl-d-aspartate receptor (NMDAR), it was not clear whether there is a selective, primary site for ketamine's antidepressant action. We found that ketamine injection in depressive-like mice specifically blocks NMDARs in lateral habenular (LHb) neurons, but not in hippocampal pyramidal neurons. This regional specificity depended on the use-d...
