Everyone’s favourite alien system is a cranky old grump — Trappist-1, the ultracool dwarf star system which was first announced back in February, has garnered a lot of interest because it harbours seven Earth-size planets. At least three of those planets are within the habitable zone that can support liquid water and potentially, life. As we’re all clamouring to understand this alien system, a duo of researchers has figured out some pretty salient information about its star’s age. They estimate it’s between 5.4 and 9.8 billion years old. Our Sun, by comparison, is only about 4.5 billion years old.
~ But has it retired yet? Anything living on these might be very ancient and hardy. Besides …
Astrophysicist believes technologically-advanced species extinguish themselves — Why haven’t we heard from intelligent life elsewhere in the universe? Retired astrophysicist Daniel Whitmire explains that using the principle of mediocracy (a statistical notion that says, in the absence of more data, that your one data point is likely to be ‘average’), that not only are we the first intelligent life on Earth but that we will likely be the only (and thus the last) intelligent life on this planet…
Unfortunately that isn’t the worst of it. Coupled with the Great Silence, it implies the reason we haven’t heard from anyone is that intelligent life, when it happens anywhere else in the universe, doesn’t last and when it does it flames out quickly and takes the biosphere with it (preventing any other intelligent life from reappearing. Sorry dolphins!).
~ Luckily, it usually appears that we’re far from ‘advanced’
Unintended experiment tracks a solar flare to the edges of the System — On 14 October 2014, our Sun let out a great big burp, a coronal mass ejection that swept through the Solar System at an incredibly fortuitous angle, because several spacecraft (and one intrepid Martian rover) detected the solar blast, resulting in an unprecedented experiment that stretched all the way from Venus to outer reaches of the Solar System.
~ Data was combined from a variety of probes and satellites, and even Mars rovers.
Milky Way from New Zealand — Christchurch’s Paul Wilson constructed a 113-megapixel photograph that captures the galaxy shimmering above a tumbling shoreline and reflected in the dark water of a dark part of the South Island.
NASA launching bacteria balloons — These enormous balloons are part of a project aptly named the Eclipse Ballooning Project, and will be used to run several experiments, one of which could help researchers preparing for a mission to Mars. Of 75 balloons, over 30 of them will carry small samples of an extremely resilient strain of bacteria called Paenibacillus xerothermodurans over 24,384m above Earth. The P. xerothermodurans samples will be attached to thin, aluminium “coupons” and attached to the outside of the balloons. According to the researchers, Earth’s stratosphere is similar to the surface atmosphere on Mars, so they will be able to get some idea of how bacteria might behave there.
~ Sounds mental.
Our life came from algae on steroids — What was life really like here on planet Earth before animals were big enough to leave fossils behind? How did living things turn from dinky capsules of genetic material into the intelligent, complex organisms that do things like fart and type curse words into posts on the internet? Scientists think they have found the answer… in algae steroids.
~ This supposition is based on the increasing diversity of organic compounds found in rock samples. Metallica, anyone?
Wind and solar health benefits surpass all subsidies — A paper in Nature Energy suggests the benefits we receive from moving to renewables like wind and solar that reduce air pollution exceed the cost of the subsidies required to make them competitive with traditional fossil fuels. Berkeley environmental engineer Dev Millstein and his colleagues estimate that between 3000 and 12,700 premature deaths have been averted because of air quality benefits over the last decade or so, creating a total economic benefit between $30 billion and $113 billion. The benefits from wind work out to be more than US7 cents per kilowatt-hour, which is more than unsubsidized wind energy generally costs.
~ So, Big Coal and Big Oil, how do you come back to that? Start paying your lobbyists even more immediately, I guess.
Electric off-roader out-torques a tank — A Utah startup has just released the specs on the Nikola Zero, a four-seat UTV (utility task vehicle, or what you may know as a side-by-side) guaranteed to make you grin like a lunatic if you ever drive one. The less crazy version produces 415 horsepower and 3,675 foot-pounds of torque. But most people will probably take leave of their senses and go for the thoroughly crazy version, good for 555 horsepower and 4,900 foot-pounds of torque.
~ So this begs the question: did Nikola Tesla have a middle name for another electric vehicle startup?
Scientists crack penguin undersea code — When Gentoo penguins swim into the open ocean to hunt for food, they often produce wierd buzzing sounds that marine biologists assume is a form of communication. By strapping cameras to the backs of these aquatic birds, scientists have finally figured out the purpose of these odd vocalisations.
~ ‘Hey, I have this weird thing strapped to me, can you help me get it off?’
Smart forever-glider — After learning a clever trick from birds, a sailplane featuring run-of-the-mill RC technology includes artificial intelligence that researchers are developing to pilot it. Using data from sensors that monitor air temperature, wind direction, altitude and other metrics (in addition to speed and location data from GPS), the AI pilot can detect when the sailplane is suddenly gaining altitude, indicating it has located a rising thermal, as birds do.
~ And us humans re generating more and more of these, thanks to our generous efforts to warm the planet.
