Disruption of normal blood flow to vital organs such as the heart, lung, and brain is the main cause of death in adults in the Western world. Current therapies require hospital facilities, since clot-lysing drugs are administered systemically or through a catheter placed within the obstructed vessel. Besides, the doses are limited by the potential […]

Natural non-wetting structures, particularly lotus leaves (Fig. 1a), have inspired the development of synthetic liquid-repellent surfaces. These surfaces rely on the formation of a stable air–liquid interface, but present limited repellency to oils with high contact angle hysteresis, failure under pressure and inability to self-heal. The paper by Wong et al. presents a novel approach […]

Have you ever observed how a drop of coffee dries? As water evaporates, its suspended particles are deposited in a ring-like fashion in a phenomenon known as the coffee-ring effect. Obviously, this effect is undesirable in the numerous practical applications that require a uniform coating. However, the way to avoid it has remained unknown. The […]

The lungs of birds move air in only one direction during both inspiration and expiration through a set of tubular gas-exchanging bronchi called parabronchi. On the other hand, in the lungs of mammals and other vertebrates, air moves tidally into and out of terminal gas-exchange structures, called alveoli (Figure 1). The work carried out by […]
