Another Einstein theory passes another test — A team of scientists used 20 years of data from several telescopes to watch how three stars orbited the centre of our own Milky Way Galaxy, Sagittarius A*. They have created a general relativity theory test in a mass regime that isn’t well-tested today. The theory checks out, yet again, for Albert Einstein’s expanded theory of motion and gravity, the theory of general relativity.
~ For now.
Program allows you to make songs with the sounds of planets orbiting the ultracool dwarf star TRAPPIST-1 — The player is part of a bigger program, aptly called System Sounds, which is the brainchild of a group of astronomers who have been studying the “resonant chain” of the TRAPPIST-1 star’s seven Earth-sized exoplanets, which were announced to the world back in February. A resonant chain describes how the alien planets’ gravitational tugs work together to keep them all in stable and circular orbits around each other and their host star.
TRAPPIST-1 represents the longest resonant chain “that has ever been discovered in a planetary system“.
~ Team with Belgian beer. Mmm.
Massive spacecraft reporting back on asteroids — Dawn is 19.8 metres (65 feet) from tip to tip and it has an ion drive! But Dawn also has a serious job to do. Launched in 2007, it has been investigating Ceres and Vesta, two mysterious protoplanets in the asteroid belt between Mars and Jupiter. These are smallish, truly ancient bodies, remnants of the early solar system (protoplanets are bodies that formed early on, some of which turned into actual planets like Earth) with plenty of secrets to tell – secrets that Dawn has been unravelling.
~ Ion drives start slow, but after 10 years Dawn is travelling at 40,233kph (25,000 miles per hour).
Cellphone tower for the moon — The German company Part Time Scientists, which originally competed for the Google Lunar X Prize race to the moon, plans to send a lander with a rover in late 2018 to visit the landing site of Apollo 17 (NASA’s final Apollo mission to the moon, in 1972.) Instead of using a complex dedicated telecommunication system to relay data from the rover to Earth, the company plans to rely on LTE technology – the same system used on Earth for mobile phone communications – because the German startup is preparing to set up the first telecommunication infrastructure on the lunar surface.
~ Boy, aliens are going to love this.
Particle accelerator in gold mine searches the stars — It took more than the 10 minutes to get down, the accelerator was sent so deep, with the elevator slowed to a crawl to protect Caspar’s delicate, antique belt and pulley as it descended from the ground floor to the “4850 Level”— this is 1478 metres (4850 feet) underground, where the dirt floors are studded with metal tracks and a light breeze blows. The Caspar team wants to learn how stars a little older than the sun synthesize heavy elements.
~ Well, isn’t that the burning question on everybody’s lips?
Ancient deep-sea creature discoveries — Last month, scientists aboard the NOAA ship Okeanos Explorer visited a poorly-explored deep sea area about 1500km west of Hawaii. From giant sea spiders and rare snailfish through to comb jellies and glass-like corals, these are some of the weirdest critters we’ve seen in a while.
~ Clearly they haven’t watched the New Zealand parliament live feed.
Sahara solar could help power the EU — In the global race to ditch fossil fuel reliance for more renewable energy sources, Europe is already making some impressive strides. That is likely to ramp up considerably thanks to a new European Union plan to build a large solar plant in the Sahara desert with the ability to generate enough power to keep much of Europe juiced up.
~ Endangering 12 lizards and three scorpions.
Gaming company turning Starcraft into an AI lab — The new release of the StarCraft II API on the Blizzard side includes a Linux package made to run in the cloud, and with support for Mac (and that other platform). It also has support for offline AI vs. AI matches, and those anonymized game replays from actual human players for training up agents, which is starting out at 65,000 complete matches, and will grow to over 500,000 over the course of the next few weeks. StarCraft II is such a useful environment for AI research basically because of how complex and varied the games can be, with multiple open routes to victory for each individual match.
~ So one day, super intelligence can win a pointless game of something.
iOS app injects the internet internet into real life — Mirage is an iOS app that’s the first to marry augmented reality’s hidden-world appeal with social media’s shareable, re-mixable content. And in doing so, it’s making AR not simply a technology of curiosity, but one of connection.
~ You know, it’s ‘augmenting’ reality.
New Zealand salt gets Tesla power — A 250kW Tesla Powerpack system has been integrated with a a 660kW wind turbine at a a salt manufacturing factory at the top of New Zealand’s South Island. The first project of its kind in Australasia, it’s about to be switched on.
Vector Energy Solutions is the company working with Dominion Salt to integrate the battery storage system, which aims to meet 75% of the site’s energy needs on-site, rather than from the national grid. The system will be fully functional before the end of the year, Vector reckons.
~ Sustainable salt …
Squishy robot future — Many researchers advancing the field of robotics are actually engineering simpler bots designed to reliably perform very basic tasks. So instead of one day facing a terrifying future filled with terminators, these squishy rolling doughnuts might be our biggest threat. Yoichi Masuda and Masato Ishikawa detail their work on these bots in a paper, Development of a Deformation-driven Rolling Robot with a Soft Outer Shell, published for the 2017 IEEE International Conference on Advanced Intelligent Mechatronics. The researchers have designed this robot to function like the simplest of machines: the wheel, in this case made from a soft material that’s squished and stretched by a set of four wires connected to an inner core.
~ Easy to pack and carry, as well.
13-million-year old skull tantalises — The unexpected discovery of a 13 million-year-old infant ape skull in Kenya is offering a tantalising glimpse of a new species that lived well before humans and apes embarked upon their very different evolutionary paths.
~ It’s a remarkable discovery as a complete skull this old has never been found before.
