The Higgs Boson’s twin could reveal our universe’s dark sector — The words most powerful particle accelerator, the Large Hadron Collider at the CERN laboratory near Geneva, has failed to find any of the hoped-for particles that would lead physicists beyond the Standard Model of particle physics. But it’s possible the LHC has been producing such pivotal new particles all along, and that we’re just not seeing them.
~ I’m definitely not seeing one.
Laser light forges graphene into the third dimension — The wonder material graphene gets many of its handy quirks from the fact it exists in two dimensions, as a sheet of carbon only one atom thick. But to actually make use of it in practical applications, it usually needs to be converted into a 3D form. Now, researchers have developed a new and relatively simple way to do just that, using lasers to ‘forge’ a three-dimensional pyramid out of graphene.
~ So soon we may move from ‘wonder’ to ‘usable’?
How accurate a clock do you really need, honestly? A team of physicists lead by Sara Campbell at the National Institute of Standards and Technology used the weirdness of quantum mechanics to create the most precise atomic clock yet. This clock employs atoms vibrating in three dimensions, using laser light to trap them in a sort-of miniature modular bookcase where they count down the tiniest measurable time units. The clock could one day help scientists devise some mind-boggling experiments.
~ They’re my favourite kind of experiments.
Rice University adds asphalt to speed Lithium metal battery — The Rice lab of chemist James Tour developed anodes comprising porous carbon made from asphalt that showed exceptional stability after more than 500 charge-discharge cycles. A high-current density of 20 milliamps per square centimeter demonstrated the material’s promise for use in rapid charge and discharge devices that require high-power density.
~ So now I’m picturing all the battery manufacturers lining up to get their asphalt.
Elon Musk says Tesla could rebuild Puerto Rico’s power grid with batteries, solar — After Puerto Rico was hit by hurricane Maria, Tesla quickly started shipping hundreds of its Powerwall batteries there to try and get power back on to some houses with solar arrays. Now, Tesla CEO Elon Musk took to Twitter to say that Tesla could rebuild Puerto Rico’s power grid with batteries and solar on a bigger scale. Puerto Rico’s electricity rates were already quite high at around $0.20 per kWh and reliant on fossil fuels.
~ Unfortunately there are issues arising with installers ripping off desperate clients.
Osprey-derived V-280 may finally be ready to replace US military helicopters — When fully operational, the V-280 Valor should offer double the speed and range of the conventional helicopters it’s aiming to make redundant. The V-280 is smaller, simpler, and cheaper than the massively complex V-22, which dates to the late ’80s. Bell designed and built the V-280 from scratch, always with an eye on making it easy to assemble and maintain, with lessons learned from building the V-22, a joint project with Boeing.
~ This could be a revolution for the military, sure, but easy-to-fly must surely have non-military benefits, to, around freight and accessibility?
Humans today have even more Neanderthal DNA than we realised — A international team of researchers has completed one of the most detailed analyses of a Neanderthal genome to date. Among the many new findings, the researchers learned that Neanderthals first mated with modern humans a surprisingly long time ago, and that humans living today have more Neanderthal DNA than we assumed.
The resulting study, now published in Science, confirms a bunch of things we already knew about Neanderthals, while also revealing things we didn’t know.
~ I think I’d worked this out just from following Twitter and the news.
