A 12 month project in Laramie cooked the resin out of scrap turbine blade in vegetable oil and got back an oil that softens tired road asphalt, but the commercial agent it was measured against is vegetable oil too
12+ hour, 27+ min ago (784+ words) Old asphalt is not dry. That is the first thing to get wrong about it. A road binder starts out as a suspension, with hard sticky particles carried in a lighter oily fraction that keeps them apart. Sunlight and air…...
Wind turbine blades usually end their lives buried in landfills, but a German manufacturer says its 63-foot wooden blades milled from laminated veneer lumber resist fatigue better and cost about 20 percent less to make
3+ day, 3+ hour ago (801+ words) A workshop floor, a gantry rail overhead, and a long pale shape lying under it that looks like furniture. It is spruce, glued up in layers, and a cutter is walking down its length taking off curls of shaving. What…...
A right whale mother NOAA has barely seen since 2005 suddenly returned with a new calf, reviving the mystery of where she disappears when survey planes lose her
5+ day, 20+ hour ago (615+ words) Known as #3593, an endangered North Atlantic right whale, has done something few researchers would expect from one of the world’s most closely monitored marine mammals. She vanishes for long periods, then suddenly returns. However, after that initial sighting, the whale…...
Sunlight a Swedish molecule holds for 18 years traveled to a bench in Shanghai and came back out through a chip of films a micrometer thick, and the whole yield was a tenth of a billionth of a watt
1+ week, 4+ day ago (787+ words) The liquid had already been charged by sunlight. Its molecules had been rearranged, atom for atom, so that the energy sat locked inside their chemical geometry rather than in a cell or a wire. Then it was crated and flown…...
A 29 year old engineering student in Argentina worked iron filler into ordinary wall plaster, and the magnetic cement that came out is troweled on like any finishing coat and needs no drill afterward
1+ week, 4+ day ago (745+ words) There is a shovel hanging on a wall in Argentina. Blade up, handle down, flat against the plaster. No bracket. No hook. No screw. There is not even a hole behind it, and there never was. The only thing touching…...
Three supermassive black holes locked in gravity are about to collide, and scientists say the aftermath could rewrite the story of how the universe was born
2+ week, 22+ hour ago (634+ words) 12.5 billion light-years away, a galaxy existed before Earth, before our solar system, before almost everything we know — and deep inside it, three supermassive black holes are locked in a gravitational entanglement astronomers have never seen at this distance. The James…...
Concrete mixed with carbon black in a 10 percent ratio became a working supercapacitor, and an improved version stores a home's daily electricity in roughly 175 cubic feet of wall rather than 1,600
2+ week, 2+ day ago (816+ words) The block on the bench looks like a paving offcut. Matte, sooty, chalky where the cement has bloomed through, one corner chipped and slightly greyer inside. No plates. No cells. No wires running through it. Two clips bite onto opposite…...
A prototype electric flying car has federal clearance to fly and is rated for 110 mph in the air, yet a 25 mph ground limit keeps it off every US highway and interstate
2+ week, 3+ day ago (745+ words) Parked, it reads as a low wide car with an oddly deep body. The whole upper surface is mesh. Look through the perforations and there are bays underneath, four at the front and four at the back, holding rotors that…...
A founder pitched a cat DNA test for 95 dollars that one investor called a "crazy idea", and the number everybody quotes for the sale 3 years later was never a price at all
2+ week, 5+ day ago (797+ words) The kit arrives in a padded envelope and weighs almost nothing. A swab, a tube, a leaflet, a prepaid return mailer. You rub the swab along the inside of a cat’s cheek, which the cat resents, drop it in the…...
Strange red dots haunted James Webb images for years and now astronomers think they have found a "black hole star" inside them
3+ week, 4+ day ago (253+ words) These weren’t faint smudges at the edge of detection. Some shone 100 billion times brighter than a star, yet carried almost no chemical fingerprint beyond hydrogen and helium. Every known category of cosmic object failed to fit. For four years, astronomers…...
