Directed evolution of enzymes at the crossroads of tradition and innovation

FEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Electronic‐Free Particle Robots Communicate through Architected Tentacles

Advanced Intelligent Systems
Communication among particle robots is crucial for developing swarm intelligence. Current particle robots rely entirely on electronic communication systems, requiring a sensor to receive signals, a transducer to send signals, a processor to process them,

Multi-functional soft-bodied jellyfish-like swimming

Nature Communications, 2019
It is challenging to reduce the size of untethered swimming robots whilst keeping their multiple manipulation and other functions. Ren et al. achieve this goal using a jellyfish-inspired soft millirobot design in an oscillating magnetic field, which can ...

Heat‐Mitigated Design and Lorentz Force‐Based Steering of an MRI‐Driven Microcatheter toward Minimally Invasive Surgery

Advanced Science, 2022
Catheters integrated with microcoils for electromagnetic steering under the high, uniform magnetic field within magnetic resonance (MR) scanners (3–7 Tesla) have enabled an alternative approach for active catheter operations.

Intelligent physical modelling systems [PDF]

Proceedings of the fourth international conference on Tangible, embedded, and embodied interaction, 2010
"What did you think you were doing?" Was the question posed by the conference organizers to me as the inventor and constructor of the first working Tangible Interfaces over 40 years ago. I think the question was intended to encourage me to talk about the underlying ideas and intentionality rather than describe an endless sequence of electronic bricks ...

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

FEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

A Low Psoas Muscle Index Was Associated With a Poorer Overall Survival in Patients Who Underwent Percutaneous Nephrostomy

Aging and Cancer, EarlyView.
In patients with malignant ureteral obstruction undergoing percutaneous nephrostomy, sarcopenia defined by a low psoas muscle index was independently associated with poor overall survival on multivariate Cox regression analysis, suggesting that preoperative assessment of psoas muscle index may aid prognostic stratification in this population.
