Just out of curiosity, how many of those mass-transit systems run 24/7365?

I remember visiting Paris which had a lovely Mass transit system ... and then running through the subway grabbing the last train before being stranded in the city Center with no way (except an expensive cab ride) back to the suburb house of our friends where we staying.

Scientists Accidentally Create Mutant Enzyme That Eats Plastic Bottles (theguardian.com) 219

Scientists have created a mutant enzyme that breaks down plastic drinks bottles -- by accident. The breakthrough could help solve the global plastic pollution crisis by enabling for the first time the full recycling of bottles. From a report: The new research was spurred by the discovery in 2016 of the first bacterium that had naturally evolved to eat plastic, at a waste dump in Japan. Scientists have now revealed the detailed structure of the crucial enzyme produced by the bug. The international team then tweaked the enzyme to see how it had evolved, but tests showed they had inadvertently made the molecule even better at breaking down the PET (polyethylene terephthalate) plastic used for soft drink bottles. "What actually turned out was we improved the enzyme, which was a bit of a shock," said Prof John McGeehan, at the University of Portsmouth, UK, who led the research. "It's great and a real finding." The mutant enzyme takes a few days to start breaking down the plastic -- far faster than the centuries it takes in the oceans. But the researchers are optimistic this can be speeded up even further and become a viable large-scale process.

Once they introduced the hard shell of the 3.5" disk it really removed a lot of the soundstage that was inherent in the 5 1/4" model.

Still, if you insist on going that route, Cassette at least provides a reasonably diverse dynamic range while preserving the warmth of the Zeros and Ones as they were originally compiled.

How do you build a city where pedestrians and cyclists can cross the street wherever they want? A pedestrian free-for-all and max speed limit for cars of 5mph?

I don't know, but they seem to be actively moving in this direction in NYC.

Whenever there is an accident, everyone immediately jumps on how it must be the driver's fault. Never mind that people constantly cross against the light, "edge out" in to the intersection before the light, or cross mid-block outside the crosswalk.

Bicycles move against traffic, not yielding to lights or pedestrians, often deciding that they get to share the sidewalk with pedestrians (as opposed to being in the street where they are legally supposed to).
