+ - Hyperloop Construction Starts Next Year With the First Full-Scale Track->

Submitted by neanderslob
neanderslob (1207704) writes "Hyperloop Transportation Technologies plans to start construction on an actual hyperloop next year. The idea is to build this to serve the proposed Quay Valley (A 150K resident solar power city in Kings County California, developed by Kings County Ventures). The project will be paid for with $100 million that Hyperloop Transportation Technologies expects to raise through a direct public offering in the third quarter of this year. The track itself will be a 5 mile loop and won't reach anywhere close to the 800mph that Musk proposed in his white paper but it's a good start!"

+ - Republicans Back Down, FCC To Enforce Net Neutrality Rules->

Submitted by Anonymous Coward
An anonymous reader writes "Republican resistance has ended for the FCC's plans to regulate the internet as a public utility has ended. FCC commissioners are working out the final details, and they're expected to approve the plan themselves on Thursday. "The F.C.C. plan would let the agency regulate Internet access as if it is a public good.... In addition, it would ban the intentional slowing of the Internet for companies that refuse to pay broadband providers. The plan would also give the F.C.C. the power to step in if unforeseen impediments are thrown up by the handful of giant companies that run many of the country’s broadband and wireless networks." Dave Steer of the Mozilla Foundation said, "We’ve been outspent, outlobbied. We were going up against the second-biggest corporate lobby in D.C., and it looks like we've won.""

Monsanto's business practices notwithstanding, what exactly is so terrible about GMO foods?

Selective breeding has been a thing for millennia and that's messing about with DNA, although in an indirect way. Changing foods so as to get rid of traits that are detrimental and add/keep traits that are beneficial is bad, why, exactly? If your opposition is anything resembling "but we don't know that it's good/bad!" then that just means that GMO should be held to a stricter scientific rigour. All things considered, science knows very little about which foods are good/bad for you, including the so called natural foods so the "but we don't know!" can be used for anything you put in your mouth.

I've replied to gweihir above pointing out the fact that his link is a commentary about an older experiment which indeed seemed deeply flawed.

However, I've actually read the report released today (not the older arXiv article, but the pdf linked in today's summary) and it seems a hell of a lot more controlled and "hands off" with regards to Rossi's involvement than what's been stated about previous experiments.

That analysis is from February 2014, the current report is from an experiment taking place for "32 days in March 2014"(that's a quote from the pdf linked in TFS) .

Not to mention the fact that the opening statements of your linked article directly contradicts the report. Your link says that it took place in Italy with Andrea Rossi's equipment, but according to the pdf in TFS the experiment took place in Switzerland with their own factory calibrated never before used equipment.

So unless the authors of that link you provided had a time machine back in February and are also delusional, they couldn't possibly be referring to this experiment.

Swedes most certainly do not, as our superior language (no bias here!) has two different words that describe what a geological continent is (kontinent) and what a geopolitical part of the world is (världsdel).

Just because English with it's hundreds of thousands of words don't make that distinction doesn't mean other languages don't.

My google fu yields the following:
Efficiency varies around the world between 13000-16000 kWh per 1000kg of aluminium.

Assuming the entire quoted weight of 100kg is aluminium (which according to the article the batteries are "made mostly of aluminium"), that's at best 50% efficient assuming your ballpark estimate of 600 kWh. Compared to an internal combustion engine that's not too shabby.

However, I feel like a demonstration like this probably used an extremely lightweight car in order to maximize the range for the test. I'm thinking 600 kWh is probably a bit too optimistic.

If it's 50 people per tutor then that itself might be the issue.

I'm currently studying medicine in Sweden (on my second semester, which is somewhat equivalent to "pre med" in the US system) and we are using PBL and focusing on it quite strongly.

Every week we have two PBL-meetings which usually involves a typical case regarding the subject the week's learning is supposed to be about (this week it's about memory and forming memories on a neuronal level in the brain and the case is about an old man forgetting things and getting lost while driving his car).

Anyway, we are in 9 person groups, 1 paid tutor who's usually a lecturer or scientist working at the university and 8 students. It's really hard to not actively take part in such a small group which seems to be the entire point.

This is of course not the only thing we do, we still have lectures as usual but they are not mandatory in any way other than the practical exercises. So far I'm liking it very much and it seems to be an extremely effective way to teach. We need to present our findings for our peers on a weekly basis and the opening session usually includes a lot of debating and discussions which help you "get into" the studying.
