We facilely prepared temperature-responsive MXene nanosheet/nanobelt fibers carrying vitamin E with a controllable release ability for wound healing, tissue engineering, and much broader applications.

This Review Article discusses progress in the development of miniaturized and ultralightweight devices for neuroengineering that are wireless, battery-free and fully implantable.

Mandrup et al. describe a panel of recombinant albumin fusions, engineered with different affinities to the human neonatal Fc receptor to program the half-life extension of a bispecific (EGFR/CD3) T-cell engager. They show that this approach generates target engagement, T-cell activation, tunable in vivo half-life extension, cellular cytotoxicity dependent on the cell surface levels of EGFR and can inhibit growth of BRAF mutated EGFR-positive tumours in mice.

3-Hydroxypropionic acid (3HP) is an important platform chemical. Here, the authors engineer Halomonas bluephagenesis by deleting newly identified degradation pathway and balancing redox state to achieve high level production of 3HP and its copolymer under open and unsterile conditions.

Industrial sugarcane ethanol fermentations are accomplished by a microbial community dominated by S. cerevisiae and co-occurring bacteria. Here, the authors investigate how microbial community composition contributes to community function and reveal the role of acetaldehyde in improving yeast growth rate and ethanol production.
