Seeking to improve the tokamak fusion reactor known as ITER, researchers have found a way to stop rogue tungsten atoms from shearing off the walls and messing with the plasma. The finding is another important milestone on fusion’s road to success.Conti… Continue reading A sprinkle of boron makes for a better fusion reactor recipe
A pair of Princeton engineers have developed a new kind of concrete that promises more than 5 times the damage resistance of the usual stuff, by poking holes in its structure.Continue ReadingCategory: Materials, ScienceTags: Concrete, Princeton Univers… Continue reading Hollow concrete mimics human bones for 5x better toughness
Nature is known for developing lightweight yet tough materials using limited, modest materials arranged into ingenious architecture. Take nacre, for example. More commonly known as mother of pearl, the shiny inner lining of some mollusks’ shells is an … Continue reading Shell-inspired cement 19x more flexible thanks to ‘engineered defects’
If a soft-bodied robot uses rigid actuators to move its body, then it isn’t really soft now, is it? An experimental new caterpillar-inspired bot gets around that conundrum by using soft, collapsible origami segments to squirm and steer its way into our… Continue reading Soft caterpillar robot moves its body by origami-power

Working-age US adults are dying at far higher rates than their peers from high-income countries, even surpassing death rates in Central and Eastern European countries, and midlife mortality rates in the UK are not great either. A new study has examined… Continue reading Working-age death rate 2.5x higher in the US than other countries. Why?
For anyone who thinks that all electric boats are essentially just aquatic golf carts, well … think again. A Princeton University student team recently broke a world speed record for electric-powered boats, with an average speed of 114.2 mph (183.8 km/h).

Although lithium can be found in hard mineral ores, it’s more often extracted from very salty (aka briny) groundwater. The latter task could soon be much quicker and eco-friendlier, thanks to a new string-based extraction technique.Continue ReadingCate… Continue reading Dangling strings slash the time and space needed for lithium harvesting
Although we’ve seen a number of systems that use sunlight to purify tainted water, their output is often quite limited. A new loofah-inspired hydrogel, however, uses sunlight to treat much more water in one go … enough to meet a person’s daily needs.Co… Continue reading Sunlight-activated “loofah hydrogel” excels at purifying water
If a robot is going to be tiny, then it better have a way of getting around the many obstacles that will block its way. A new type of robot takes a unique approach to doing so, by jumping like a click beetle.Continue ReadingCategory: Robotics, Technolo… Continue reading Tiny robots copy the click beetle to jump over obstacles
