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.
More than 800 American energy and Earth science researchers have signed a letter to Donald Trump outlining six steps they’re urging him to take to address human-caused climate change to protect “America’s economy, national security, and public health and safety.” The letter is accompanied by a public change.org petition to “Tell Trump To #ActOnClimate.” Here […]
James Delingpole is an invective-hurling anti-climate science columnist who has candidly admitted that he doesn’t bother to read scientific papers, calling himself a “an interpreter of interpretations.”
Kratom (previously) is a widely used herb that has been very effective in treating opioid withdrawal and other chronic, hard-to-treat conditions — it also became very controversial this year because the DEA decided, without evidence, to class it as a dangerous drug, and then changed its mind (unprecedented!) after a mass-scale petition that included interventions […]

Unlike traditional lighters, the SaberLight features an electronic plasma beam that’s both rechargeable and butane-free. This sleek lighter is even approved by TSA, so you’ll never be stuck buying lighters you’ll just have to throw away partially used. For some people, like me, this is a pretty big game-changer. The SaberLight’s beam is actually both hotter and cleaner […]
