Oumuamua also has a weird shape — A few weeks ago an interstellar asteroid, now named Oumuamua, was discovered passing through our solar system. Being the first interstellar asteroid to ever be observed, a flurry of observations soon followed. An article in Nature revealed Oumuamua is more bizarre than originally thought, since it it is elongated, with a 10:1 aspect ratio, and rapidly rotating. This conclusion is based upon comparisons of its time-dependent light curve to those from 20,000 known asteroids.
Two teams simultaneously unearthed evidence of an exotic new particle — A few months ago, physicists observed a new subatomic particle – essentially an awkwardly-named, crazy cousin of the proton. Its mere existence has energised teams of particle physicists to dream up new ideas about how matter forms, arranges itself and exists. Now, a pair of new research papers using different theoretical methods have independently unearthed another, crazier particle predicted by the laws of physics
~ So here I join in the general excitement that, uh, doubly-b tetraquark could exist. Woot.
Latest weather-tech in space — A fastidiously clean scanning machine named VIIRS has been launched into Earth orbit on a Delta II rocket from Vandenberg Air Force Base in California, just one instrument outfitting a next-generation weather satellite. The Visible Infrared Radiometer Suite is a washing machine-sized sensor, built to capture light and other waves that bounce off the surface of Earth. It collects those reflections, turning them into data about our planet, the oceans, land and vegetation cover, ice caps, volcanic plumes, and global temperatures—allowing accurate weather forecasts, wildfire and fishing fleet tracking, and climate monitoring.
~ I have one in the laundry, although this one actually does the washing, no matter what the weather is doing.
Musk makes it right on time with Australian battery project — Elon Musk will get paid for building the world’s largest lithium ion battery in South Australia, with testing on the 100-megawatt project about to begin ahead of next week’s December 1 deadline to build it in 100 days, or it’s free.
State premier Jay Weatherill has announced that regulatory testing at the site, which is paired with French energy business Neoen’s Hornsdale wind farm, 230km north of the capital, Adelaide, will begin within days.
~ Gosh, doesn’t Elon just look so pleased and happy?
Robot salad — A startup called Iron Ox is taking the first steps toward roboticizing greenhouse farming, which has so far stubbornly resisted automation. In the very near future, then, the salad on your table may come from the hand of a robot.
~ Er, the robot has hands, then? Better make the thumbs green.
UCLA researchers use solar to create and store hydrogen — UCLA researchers have designed a device that can use solar energy to inexpensively and efficiently create and store energy, which could be used to power electronic devices, and to create hydrogen fuel for eco-friendly cars.
The device could make hydrogen cars affordable for many more consumers because it produces hydrogen using nickel, iron and cobalt – elements that are much more abundant and less expensive than the platinum and other precious metals that are currently used to produce hydrogen fuel.
~ Making electricity and fuel with the same device is a real breakthrough.
Microbial kill-switches — Scientists at Harvard have developed a pair of new kill switches that can be used to thwart bioengineered microbes that go rogue. Researchers have been testing the use of bioengineered microbes for a variety of purposes, from the diagnosis of disease in the human body to the neutering of mosquitoes. But there remain concerns about releasing manipulated microbes into nature. Could their augmented genes have unintended consequences? Could they morph and proliferate?
~ Somehow I’m not convinced this is safer.
Ancient dogs were already on the leash 8000 years ago — A new analysis of ancient rock art demonstrates that humans hunted with dogs on the Arabian Peninsula over 8000 years ago – and it looks like those dogs wore leashes.
There are a lot of questions around the origin of dog domestication, such as when, where and how it happened. But a newly analysed set of panels depicts scenes of leashed dogs hunting alongside humans. Not only would this be the “earliest evidence of dogs on the Arabian Peninsula,” according to the study published recently in the Journal of Anthropological Archaeology, but it’s also the “earliest evidence of leashes“.
~ Or maybe it was the dogs that had humans on the leashes … also, did the men really hunt with erections? That seems a little counterproductive if you ask me.
