Submission + - International Space Station to Trial Aussie-designed Ion Thruster (abc.net.au)

theweatherelectric writes: Barney Porter from the Australian Broadcasting Corporation writes, "An Australian-designed rocket propulsion system is heading to the International Space Station (ISS) for a year-long experiment that ultimately could revolutionise space travel. The technology could be used to power a return trip to Mars without refuelling, and use recycled space junk for the fuel. Former University of Sydney student, Dr Paddy Neumann — now of Neumann Space — and two co-inventor professors from his alma mater have developed an ion thruster that could replace the current chemical-based rocket propulsion technology, which requires huge volumes of fuel to be loaded onto a spacecraft."

Comment Deterrent Not Prevention (Score 1) 222

So, the idea that this is newsworthy, is the shock to me. In Junior High (a goodly number of years ago) the benefit of a Master lock was that when you forgot or lost your key, you took a buddies shoe, whacked it solid on the top and it came open. If you're buying a Master Lock, or any similar style lock, that it is somehow theft-proof is naive at best. You're buying a deterrent. On your school locker, the school ne'er-do-well' can't simply rummage your stuff as he slinks on through. sure he could take his shoe and whack it open, but that's noisy, and likely draw suspicion. Master Lock sells stuff that generally does the job, just recognize what you're buying and get on with life.

You're almost right.

It is not 'keeping the aliens from fucking with your brain waves'.

As we all know, they are much more intelligent than we, and they no longer copulate in the traditional sense. What they do, is they 'copulate with brain waves' (switched verbs for clarity of point). And when they do abduct you (given your incredible advanced intellect it's a given), you know what you're in for.

And by the way, the reason foil hats work, is that as we all have probably noticed, someone wearing an aluminum foil hat, looks utterly ridiculous, which completely shoots the cross species sex appeal.

Comment Over Excited Marketing directors? (Score 1) 328

So, my experience may be part of the reason the market is not there. In my way-back machine, I had one of the original "Pocket Pc's", a HTC 8525. I liked the device (it was really more of a tiny computer than phone) with the slide out keyboard, and integrated well with Office. When I finally laid it to rest (sadly), the one issue I had was that my eyes no longer could cope with the screen size (I tended to use it to type full emails, not just quick texts) and some spreadsheet work. In any case, at the phone store, I asked; "What's your biggest device?" And was handed the original Galaxy Note (which I just replaced with a Note 4). Through this period, tablets were theoretically the "hot item" (as well as all the electronic book thingies). Never saw the purpose. With the Note, I could pretty much do what the folks carrying both the phone, and tablet around could do. And it was a phone. The marketing gurus, I believe, missed the impact of the larger devices (really can't call them phones, and phablets is too goofy). For what people use a tablet for the Galaxy (and the iPhone 6+) handle. If I need computing power, either a desktop or laptop, but not a tablet.

Submission + - What consumers want from their smart homes (robohub.org)

Hallie Siegel writes: Despite the energy savings and environmental friendliness that has often been associated with smart home technologies, a recent poll showed that consumers want their homes to optimize for their comfort level and personal preference (45%). Security/Safety and Energy Savings tied in second place (18%). Environmentally friendliness came in at only 11%. Note that the three most voted choices have direct advantages for the user, as opposed to Environmental Friendliness, which is primarily a societal benefit.

Submission + - Amazing New Invention: A Nail Polish That Detects Date Rape Drugs (geek.com)

stephendavion writes: Checking to see if your drink has been tampered with is about to get a whole lot more discreet. Thanks to the work of four North Carolina State University undergrads, you’ll soon be able to find out without reaching for a testing tool. That’s because you’ll already have five of them on each hand. The team — Ankesh Madan, Stephen Gray, Tasso Von Windheim, and Tyler Confrey-Maloney — has come up with a creative and unobtrusive way to package chemicals that react when exposed to Rohypnol and GHB. They put it in nail polish that they’re calling Undercover Colors.

Comment Where From? (Score 1) 303

So, the main use of carbon tet was manufacturing the CFC's. this is replacing a chlorine with a fluorine. Done in a manufacturing facility. So, if this is due to it still being used for that purpose, you'd be able to look at the presence of the products. If plants have leaky manufacturing processes, you should see the carbon tet as well as the CFC's.

If I were to guess, it's degassing from old landfills.

Chemically it's not going to happen. Carbon tet is fluorinated to make the CFC's. The CFC's, in use are largely unreactive. We need to recharge due to leaks, not due to decompostion. In the atmosphere, the CFC's aren't going to have a ready source for the chlorine to somehow react back to carbon tet.

Submission + - How to read a microbiome study like a scientist.

bmahersciwriter writes: Scientific reports have increasingly linked the bacteria in your gut to health and maladies, often making wild-sounding claims. Did you hear about the mice who were given fecal transplants from skinny humans and totally got skinny! Well, some of the more gut-busting results might not be as solid as they seem. Epidemiologist Bill Hanage offers five critical questions to ask when confronted by the latest microbiome research.

Comment So why bother with Brand Recognition (Score 1) 653

Fluke is a manufacturer of higher quality testing equipment, and has put in a lot of effort on brand recognition. It is not by accident that these units match. Now it may be that Sparkfun simply purchased a bunch of cheap Chinese units who had copied the trademarked systems, but it's not Fluke who is at fault here nor should be villanized.
