In a global-health context, commercial centrifuges are expensive, bulky and electricity-powered,
and thus constitute a critical bottleneck in the development of decentralized, battery-free …

Here we describe an ultra-low-cost origami-based approach for large-scale manufacturing
of microscopes, specifically demonstrating brightfield, darkfield, and fluorescence …

We demonstrate universal computation in an all-fluidic two-phase microfluidic system.
Nonlinearity is introduced into an otherwise linear, reversible, low–Reynolds number flow via …

We develop a coherent view of the form and function of the integument of water-walking
insects and spiders by reviewing biological work on the subject in light of recent advances in …

Controlling the wetting behaviour of liquids on surfaces is important for a variety of industrial
applications such as water-repellent coatings 1 and lubrication 2 . Liquid behaviour on a …

Cilia and flagella are fundamental units of motion in cellular biology. These beating, hair-like
organelles share a common basic structure but maintain widely varying functions in …

INTRODUCTION Mechanical power, whether for launched missiles or running humans, is
limited by the universal, physical trade-off between force and velocity. However, many …

Mechanical force organizes life at all scales, from molecules to cells and tissues. Although
we have made remarkable progress unraveling the mechanics of life's individual building …

The variability of bird beak morphology reflects diverse foraging strategies. One such feeding
mechanism in shorebirds involves surface tension–induced transport of prey in millimetric …

Rational control over the morphology and the functional properties of inorganic nanostructures
has been a long-standing goal in the development of bottom-up device fabrication …
