Researchers are developing a new nanotech process to create a self-healing material that repairs itself if damaged The scientists from the Fraunhofer Institute and Duisburg-Essen University peppered a layer of electroplating with fluid-filled nanocapsules. If the electroplating is scratched, the nanocapsules burst open to fill the damage. From Fraunhofer-Gesellschaft:
Mechanical bearings are one example of possible applications – the materials of the bearings usually have a electroplated coating, in which the capsules can be embedded. If there is a temporary shortage of lubricant, part of the bearing's coating is lost, the capsules at the top of the layer burst and release lubricant. The bearing is not therefore damaged if it temporarily runs dry. The researchers have produced the first copper, nickel and zinc coatings with the new capsules, although surface coverage does not extend beyond the centimeter scale. Experts estimate that it will be another one and a half to two years before whole components can be coated. In a further step the team worked on more complex systems – involving differently filled capsules, for example, whose fluids react with one another like a two component adhesive.
Olivia P. Judson’s paper in Nature, The energy expansions of evolution, presents a novel, beautifully written and presented frame for looking at the history of life on Earth: as a series of five epochs in which energy became more abundant and available to lifeforms, allowing them to scale up in complexity and fecundity: geochemical energy, […]
Beatboxer Tom Thum had ENT doctor and laryngeal surgeon Dr Matthew Broadhurst shine an endoscopic camera down his throat while beatboxing: “I wanted to find out how my larynx functioned when beatboxing compared to how it functions normally with speech, and whether or not there were any abnormalities in my laryngeal anatomy. I also had […]
Gastric bypass surgery is remarkably effective at promoting weight-loss (it cuts the long-term risk of early death from morbid obesity by 40%), and it’s long been presumed that the major action by which it worked was that, by bypassing the parts of the gut where most food absorbtion takes place, it limited the calories that […]

While some people still maintain that everything in Apple’s walled garden “just works” and is immune to the rampant malware of the Windows world, the reality is different. The Mac’s growing market share has made it a much more viable target for malicious actors, and its built-in tools aren’t always enough to fix things. Drive […]
