Advanced Science, EarlyView.3‐Hydroxylactams are obtained from phthalimides through a heterogeneous catalyzed chemoselective hydrogenation, able to stop the process at the first hydrogenation level. By using a rationally designed [Ag/Al2O3] recyclable solid nanocatalyst, a wide range of cyclic hemiamidals are accesed through a full atom‐economical reaction that preserves (hetero ...

American Journal of Botany, EarlyView.Abstract Why did it take so long for angiosperms to diversify after they arose? Here I consider the indirect but potentially crucial impact of the “photosynthetic revolution” on plant–herbivore coevolution. Increased vein density in fossil leaves implies a doubling in photosynthesis 125–100 million years ago.

Animal Models and Experimental Medicine, EarlyView.In this review, the pathological, molecular, and cellular changes observed in the COVID‐19 lung are compared to those in the laboratory rat treated with monocrotaline (MCT). Similarities that reflect common changes associated with inflammation and endothelial cell dysfunction are observed in both states, leading to a lung pathology characterized by ...
