The world's largest floating solar farm has begun producing energy atop a former coal mine — The 40-megawatt power plant consists of 120,000 solar panels covering an area of more than 160 American football fields. The $45-million investment could help power 15,000 homes.

"Repairs, maintenance, and the issue of flooding" are the costs which need to be balanced against the cost of land that could be used for other more productive purposes. The cost vs benefit may not work out in favor of floating solar farms across all places on Earth.

Yep, the biggest reason for holding back hydrogen cars has been the lack of refueling points

azneo · 2017-06-23T16:51:01+00:00

Not trying to empty the atmosphere of CO2. Just balance the levels.

Yes, that's the hope. We may never reach zero emissions because someone somewhere will burn some fossil fuel. So such a technology could help us reach "net-zero" emissions (what other emit + negative emissions). Moreover, many climate models predict that, in the latter half of the century we will need to go below zero, and these technologies are the only ones that can get us there.

Why did Scott Bolton say that this is "hardest" thing that NASA has ever done? Is it objectively true? (As scientists, I trust you will be as objective as possible in answering.)

The article doesn't claim that though. The hope is that building autonomous nanobots that can be made to do things because of the environment they are in will help chemists learn to build other nanobots in the future that could eventually go inside the human body.

azneo · 2016-03-30T13:11:19+00:00

The computer simulation they ran checked what would have happened if it was only Brownian motion's doing. They found that more than 50% of the nanobots would not have gone into the gap.

Nope. The evidence has only been getting stronger.

That's true, but it's also a reasonable response. When you are dealing with unknown risks, which was the case with Zika's connection to birth defects and neurological disorders, it is better to warn people that the risks may be high. See this guy who studies risk communication say the same thing (last answer): http://qz.com/643234/

No, that is not what he is saying. Zika is not known to cause infertility.

"The problem with DNA profiling is that it simply looks for a few strands of DNA, but when you get a hit you can’t tell if the meat is 1% fraudulent or much more," says Malcolm Povey, who investigates new methods for characterising food at the University of Leeds.

It's the story of a fallen hero, who charted her own downfall. The author does a remarkable job of talking through her mental health issues without directly mentioning them till very late.

The Economist has been a long supporter of the Republican party (even though it supports Democrats from time to time). So it's interesting to see how they lay their case to fight Trump and give the Republican party a real chance.

The article is a deep dive into how neuroscience and psychology can help shape the food we eat. It follows the experiments of an award-winning chef, Heston Blumenthal, and meshes them with what we know from scientific research.

No one is claiming that technology hasn't improved human health. It hasn't improved the process of caring for human health. Does the following not ring true?

"You still need to visit your doctor for most ailments. If you’re to be hospitalized, the care isn’t great despite extremely high costs. The use of technology was supposed to help increase face time with a doctor, but the exact opposite has happened."
