Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications
Advanced Materials Technologies, EarlyView.A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.

Diel Feeding Ecology of Three Species of Aquatic Insects
Journal of Freshwater Ecology, 1995 Abstract Aspects of the diel feeding ecology of the odonate nymphs Anax Junius and Ischnura verticalis and the ephemeropteran Callibaetis fluctuans were examined over a 24-h period in a small pond. Detrital material was the primary food of both A. Junius and I. verticalis. Aquatic insects (mainly C.

Clickable Microgel Inks Enable Spatioselective, Multi‐Stimuli Programmable Assembly of Materials
Advanced Science, EarlyView.Clickable microgel inks enable direct ink writing of hydrogel architectures with intrinsic spatioselective and programmable multi‐responsiveness. By combining pH‐responsive and temperature‐responsive microgel building blocks through Diels‐Alder interparticle crosslinking, the assemblies exhibit controllable swelling and shape changes.
