A fourth gravitational wave has been detected — Astronomers have made a new detection of gravitational waves and for the first time have been able to trace the shape of ripples sent through spacetime when black holes collide. The announcement, made at a meeting of the G7 science ministers in Turin, marks the fourth cataclysmic black-hole merger that astronomers have spotted using Ligo, the Laser Interferometer Gravitational-Wave Observatory.
The latest detection is the first to have also been picked up by the Virgo detector, located near Pisa, Italy, providing a new layer of detail on the three dimensional pattern of warping that occurs during some of the most violent and energetic events in the universe.
~ Can’t think of a smart-arse thing to say about this, so I will leave that up to the researchers: “Overall, the volume of universe that is likely to contain the source shrinks by more than a factor of 20 when moving from a two-detector network to a three-detector network.” So there.
Pluto’s skyscraper ice shards — When NASA’s New Horizons space probe zipped past Pluto in 2015, it revealed portions of the dwarf planet’s surface were strewn with what could only be described as gigantic blades of ice, many of which extended into the Plutonian sky for hundreds of metres. Finally, after nearly two years of research, a team of scientists think they have figured out the nature of these odd features and how they came to appear on the surface.
~ I would have picked something to do with temperature …
Low-tech rover destined for Venus — The surface of Venus is, at approximately 450°C (850° Fahrenheit), hot enough for paper to spontaneously combust. Its atmosphere, an oppressive mix of carbon dioxide, nitrogen, and sulfur dioxide, is dense enough to crush a submarine. While certainly inhospitable to humans, is almost just as rough for robots. The last time a bot visited the surface of Venus was in the mid-’80s, when the Soviet Union sent its Vega lander to capture data about the planet’s soil. It lasted for less than an hour.
So NASA is going low-tech and is working on a boxy, tank-like bot that rolls around on treads (main picture, above), making it impervious to Venus’ rough terrain. Those treads are powered via a wind turbine that captures the planet’s whipping wind gusts and stores that power inside springs before distributing to the various systems on the rover.
~ It’s also using light refectors rather than fragile radio.
Chinese researchers carry out Base Editing to correct mutation — Chinese researchers have taken tissue from a beta-thallasemia patient, created cloned embryos from that patient’s cells, and used a genetic editing technique known as Base Editing to correct the gene mutation that causes beta-thallasemia. The embryos were not implanted in a womb, so no actual babies were created during the procedure.
~ “Precise chemical surgery” indeed.
Toyota, Mazda and, ah, Denso collaborate for electric cars — With governments around the world increasingly mandating some percentage of their countries’ car companies’ sales be of electric vehicles, the onus is on those brands to find more efficient and cost-effective ways to develop new models. Toyota is spearheading a new enterprise with the help of Japanese partner Mazda [which gives Ford a look-in, with it’s 33% stake in Mazda] and electronics powerhouse Denso to create standardised technology for EVs that the car brands can share in the future.
~ One suggestion: Denso should maybe consider changing its name to Clevero.
Vacuum company Dyson aims to build a radically different electric car — The billionaire who revolutionized the vacuum cleaner said 400 engineers in Wiltshire had been working since 2015 on the £2.5 billion project. Dyson says the car’s electric motor is ready, while two different battery types were under development that he claimed were already more efficient than in existing electric cars. Dyson said consumers would have to “wait and see” what the car would look like.
~ Going by Dyson’s other products, the mind boggles. And unlike most of their other products, they’ll hope it doesn’t suck.
Bot armies that build things — At SRI International in Silicon Valley, researchers have developed perhaps the most impressive microbot army yet: the MicroFactory. It’s an ant colony made robotic, with half-millimeter machines zipping around to construct truly impressive structures. It could well be a glimpse at a future where 3-D printers give way to swarms of robots that cooperatively build stronger, more complex structures. The setup of the MicroFactory is fairly straightforward. The foundation is a circuit board that generates a magnetic field. The little robots themselves are magnets
~ I will really start to worry when their evolution passes from human direction.
McLaren body armour — Developed by McLaren Applied Technologies for a “client X”, the armour is designed to “help protect vital organs after surgery”. The fully wearable composite shield does the job of the rib cage — protecting vital organs including the heart and the lungs, with the garment providing further protection from unexpected low energy impact.
According to McLaren, it’s designed to conform precisely to the client’s physique and is manufactured from a combination of materials, including carbon, Zylon and Dyneemafibres, as well as “highly-toughened resin”.
~ I guess this is really throwing down the Zylon and Dyneemafibre gauntlet to the other supercar companies …
