Odd interstellar observation could unlock Dark Matter mystery — An international team of astronomers found a series of strange shapes in data coming off of distant sources of radio waves. They hypothesise that the dips come from some mysterious sources passing in front of the light, maybe black holes or the centres of clusters of stars. If their hypothesis is correct, they think they may have found a new way to probe those sources – sources with masses difficult to observe by other means.
~ Blips and dips taking on huge importance.
Diamonds on Neptune and Uranus — Researchers using the Linac Coherent Light Source at Stanford have demonstrated in the lab, with one of the brightest sources of X-rays on the planet, that the depths of these ice giants are perfect for the formation of diamonds.
~ Ooh, I know, let’s have a space war over the rights to them!
Probe still talks to Australia — For the 40 years since NASA launched the two Voyager space probes on their mission to explore the outer planets of our Solar System, Australia has been helping the US space agency keep track of the probes at every step of their epic journey.
CSIRO operates NASA’s tracking station in Canberra, a set of four radio telescopes (dishes) known as the Canberra Deep Space Communication Complex (CDSCC).
Four decades on and the Australian tracking station is now the only one with the right equipment and position to be able to communicate with both of the probes as they continue to push back the boundaries of deep space exploration.
~ I’m amazed Australia even lets any signals in, myself. Shouldn’t they be quarantined in a concentration camp for a few years first? And only released, if they survive, when they’re lives have been completely ruined?
Musk’s new spacesuit — Elon Musk’s new Space-X spacesuit is white, in contrast to the very blue spacesuits unveiled by Boeing in January. These are not, strictly speaking, “space suits.” More properly they are they are flight suits designed to be worn during the ride to space and back again on the ride back down to Earth. They have a limited time in which they can operate in a full vacuum and are not intended for spacewalks.
~ Wonder if it smells a bit musky inside.
Big power from tiny Mercedes engine — The forthcoming Mercedes ‘hypercar’ Project One gets most of its oomph from a turbocharged 1.6-litre V6 engine. That may seem minuscule for this sort of use case, but this machine is a close cousin to the one that powered the car Lewis Hamilton drove to an F1 championship in 2015. Changes have to do with how, and how high, the engine revs.
~ Only oligarchs need get excited, and then you’ll be driving it at 10% of it’s potential anyway. Haha, sucks to be you.
China relaunches world’s fastest train — Seven pairs of bullet trains will be operating under the name Fuxing, meaning rejuvenation, according to the South China Morning Post. The trains will once again run at 350kph, with a maximum speed of 400kph (248 mph).
Following a fatal crash in 2011, the high speed train service reduced its upper limit from its then-record holding 350 km/h (217 miles/hour) to 250-300 km/h (155-186 miles/hour). It is reported the train service will use monitoring systems to automatically slow the trains in case of emergency. The Beijing-Shanghai line will begin operating on 21st September and will shorten the nearly 1319km (820 mile) journey by one hour, to four hours thirty minutes. Nearly 600 million people use this route each year, providing a reported $1 billion in profits . The Beijing-Tianjin-Hebei route begins operation now.
~ Wonder how the ticket price stacks up to air travel? It’s much less polluting, of course.
Laptop batteries running homes — DIY Powerwall builders from around the world are harvesting old laptop batteries and turning them into powerful batteries capable of supplying energy to their entire homes. “It’s the future. It’s clean, simple, efficient and powerful,” Jehu Garcia, one of the most popular powerwall builders, told me. He and people like him are deciding for themselves what the future of alternative energy will look like, instead of waiting for technology companies to shape it for them.
~ Yep, it’s all green and clean … and then they die and you need to get rid of them.
Gates and Branson fund ‘clean’ meat — A large global agricultural company has joined Bill Gates and Richard Branson to invest in a nascent technology to make meat from self-producing animal cells. Memphis Meats produces beef, chicken and duck directly from animal cells without raising and slaughtering livestock or poultry, and raised $17 million from investors including Cargill, Gates and billionaire Richard Branson, according to a statement Tuesday on the San Francisco-based startup’s website.
~ Fake cow, chicken and yuck.
Protect your DNA with encryption — Bejerano and Boneh published a paper in Science about a cryptographic ‘genome cloaking’ method. The scientists were able to do things like identify responsible mutations in groups of patients with rare diseases and compare groups of patients at two medical centres to find shared mutations associated with shared symptoms, all while keeping 97% of each participant’s unique genetic information completely hidden. They accomplished this by converting variations in each genome into a linear series of values. That allowed them to conduct any analyses they needed while only revealing genes relevant to that particular investigation.
~ Honestly, though, you’re just not that important. There are billions of you. Literally.
Italians have been tanking up on wine for ages and ages — In a study published in Microchemical Journal, researchers describe their big find of a jar dating back to the early 4th millennium BCE. After chemically testing the piece of pottery, the team found traces of tartaric acid, which is one of the main acids in wine. Its salts – called tartrates – were also found in the jug.
~ Six thousand years of boozing, wow!
Babylonians may have invented trigonometry — The Plimpton 322 tablet, discovered in the early 1900s in what is now Iraq, has long divided mathematicians confused by its columns and rows of numbers. But researchers from the University of New South Wales now say the 3700-year-old broken clay tablet is a trigonometric table. That would mean the Babylonians were 1000 years ahead of the Greeks, who are credited with creating trig.
~ So generations of school students have been cursing the wrong people.
