Radio detection of interstellar DCO/+/
The Astrophysical Journal, 1976 The J = 1-0 transition of the deuterated formyl ion, DCO(+), has been detected in emission from NGC 2264 and DR 21(OH) and from the cool dust cloud L134. Estimates for the column-density ratios of H(C-13)O(+) to DCO(+) are given for NGC 2264 and DR 21(OH); lower limits for the ratios are given for five other clouds.

Cobalt‐Catalyzed Asymmetric Construction of Boron Stereocenters With C–N Axial Chirality
Advanced Science, EarlyView.A cobalt/Salox‐catalyzed one‐pot annulation enables enantioselective formation of B‐stereogenic centers and C─N axial chirality via C─H/N─H annulation, affording diverse fluorescent products with high stereocontrol and optoelectronic potential. ABSTRACT The efficient construction of boron stereogenic centers alongside axial chirality remains a ...

International Journal of Cancer, EarlyView.The evidence on the rising incidence of colorectal cancer among adults below 50 years of age largely stems from the United States. Using high‐quality cancer registry data for the 2003–2023 period in Germany, this study found a moderate increase of early‐onset colorectal cancer incidence that was limited to those aged 20–39 years and more pronounced ...
