Cat's eyes: Designing the perfect mixer

As any amateur baker knows, proper mixing is crucial to a perfect pastry. Mix too little and ingredients will not be evenly distributed; beat instead of fold, and a soufflé will fall flat. Mixing strategies are even more ...

Observation of mechanical bound states in the continuum in an optomechanical microresonator

High-Q mechanical resonances are desired in many applications. The conventional wisdom relies on minimizing the size of the supporting structure of mechanical resonators, which renders the fabricated mechanical device fragile.

New insights put a freeze on the mechanisms for safely cryopreserving biological materials

Cryopreservation involves preserving biological materials, such as cells, tissues, and organs, at ultra-low temperatures so that they can be revived and used at a later date. To achieve cryopreservation such that the preserved ...

Where cells go: Mechanical and chemical cues collaborate to guide them

Living cells respond to biochemical signals by moving toward those at higher concentration, a process carefully mapped out by biologists over the past several decades. But cells also move in response to mechanical forces, ...
