On top of these points I would like to add scale-up. Being able to produce an improved button-sized battery won't cut it. You'll need tons and tons of the new material, which means a stable and efficient production line is needed. And, of course, you'll need to develop and build said production line, which is something that the lab-rats often just wave their hands over, dismissing it as engineering "details".

You might want to check out Stanislaw Lem's "His master's voice". He writes about the futile attempts of humanity in decoding an alien signal sent to earth, not only because of the difficulty of the encoding itself, but also due to the chasm between the two civilizations, mindsets etc. It is very dark and pessimistic, but definitely a good read.

You'll have to acknowledge though that in the rest of the "western" world religion and science are kept nice and separate. For example, debates on whether kids at school should learn about the genesis or evolution are very, very seldom. They are both taught at school, one at religion class and the other at biology class. People do go to church, pray etc. but they also know that this has nothing to do with science.


Ninety-Nine Percent of the Ocean's Plastic Is Missing 304

sciencehabit writes Millions of tons. That's how much plastic should be floating in the world's oceans, given our ubiquitous use of the stuff. But a new study (abstract) finds that 99% of this plastic is missing. One disturbing possibility: Fish are eating it. If that's the case, "there is potential for this plastic to enter the global ocean food web," says Carlos Duarte, an oceanographer at the University of Western Australia, Crawley. "And we are part of this food web."

The only advantage of a smartwatch over a smartphone is that it can't be that easily stolen/lost/broken. I would therefore like it to take over more critical functions that, however, require a minimum of interaction with the smartwatch. Have it automatically unlock/lock my house/car using proximity sensors, for example. Of course it should provide all sorts of time-telling functions, like time-zone conversion and it should have calendar reminders. It should be 100% waterproof so I can wash my hands without having to take it off. Did I mention that the battery should last for at least a year? Don't bother with anything inferior than that.
