New Perspectives on Glacial Geomorphology in Earth’s Deep Time Record
Frontiers in Earth Science, 2022 The deep time (pre-Quaternary) glacial record is an important means to understand the growth, development, and recession of the global cryosphere on very long timescales (106–108 Myr).

Animal emergence during Snowball Earths by thermosynthesis in submarine hydrothermal vents [PDF]
, 2009 Darwin already commented on the lateness in the fossil record of the emergence of the animals, calling it a valid argument against his theory of evolution^1^.

Advanced Materials, EarlyView.This work reports a direct, biocompatible method to synthesize UiO‐66, enabling one‐step encapsulation of proteins without compromising crystallinity or activity. Using advanced in situ and ex situ techniques, the study reveals that proteins integrate concurrently with MOF growth, forming crystalline protein@UiO‐66 nanoparticles, and provide insight ...

Advanced Materials, EarlyView.A hierarchically structured metal–organic framework (eMIL) is shown to host the complete six‐enzyme biosynthesis pathway for the anti‐cancer pigment violacein, reshaping reaction dynamics and multiplying in vitro yields. eMIL nanoreactors deliver this reconstituted bacterial multi‐protein system into mammalian cells, where cell‐derived substrates and ...

Multivalent Glycopolymer Design Unlocks Antimicrobial Activity of 2‐Deoxyglucose
Angewandte Chemie, EarlyView.New approaches to combat antimicrobial‐resistant pathogens are needed. Here, scaffolding a nonmetabolizable sugar (2DG) on a polymer backbone is shown to significantly improve its antimicrobial activity. ABSTRACT With the increasing prevalence of multidrug‐resistant (MDR) pathogens, last‐line therapeutics such as cyclic peptides are insufficient ...

Far-field modelling of THM processes in rock salt formations
Open GeomechanicsGlaciation cycles are one aspect to be considered in assessing the safety of deep geological repository sites for long-term radioactive waste storage. This study examines the impact of time-dependent boundary conditions and thermo-hydro-mechanical (THM)

A persistent and dynamic East Greenland Ice Sheet over the past 7.5 million years [PDF]
, 2016 Climate models show that ice-sheet melt will dominate sea-level rise over the coming centuries, but our understanding of ice-sheet variations before the last interglacial 125,000 years ago remains fragmentary.

3D Printed Omniphobic Slippery Liquid Infused Porous Surfaces for Low Surface Tension Repellency
Advanced Materials Technologies, EarlyView.A 3D printing strategy fabricates omniphobic slippery liquid‐infused porous structures with lubricant reservoirs and interconnected microchannels. A post‐printing surface treatment modifies the porous surface to ensure compatibility with the infused fluorinated lubricant.
