Researchers may have brought the renewable energy future one step closer. A new electrode can accomplish the hydrogen evolution reaction (HER) in acidic conditions, making the technology both cheaper and more effective. The process is helped by a smart form of graphene. The electrolysis of water to hydrogen is vital for energy storage in a…

 Minimizing air resistance and friction with snow is key to elite performance in downhill skiing. Experiments in wind tunnels have revealed the total drag experienced by skiers, but have not provided precise data on which parts of the body cause the most air resistance when adopting the full-tuck position. A new study published in the European…

At the back of the retina in adult vertebrate eyes is a highly differentiated layer of cells known as the retinal pigment epithelium (RPE). These cells do not normally multiply or migrate in adults, but in humans they do so in response to retinal trauma. They then pass through a transitional state of multipotency, with…
