My latest for @science.org: Researchers at Nokia Bell Labs have done something remarkable -- turned a submarine telecom cable in the Pacific Ocean into, in effect, an array of 44,000 (!) seismic sensors.
That's potentially DAS-like precision -- and it doesn't need its own dedicated fibers.

My latest: Let's start with the easy part. Yes, long-lived airplane contrails warm the Earth and it's great to not do that. But just how much they warm, and where -- and how much more CO2 you can add to the atmosphere to avoid them?
That's where it gets harder.

ICYMI: NSF has followed through with its plan to end the lease on its Antarctic icebreaker, many years before necessary, with almost no congressional pushback. Now there's a mad scramble to fill the gap with less capable ships. @science.org's Jeff Mervis followed the story up:

This is the second part of the work we covered here, highlighting that CO2 is the dominant forcer in temperature and sea level changes during ice age cycles.
(It's also a great chance for others to cover; this has not been widely reported. There's even an old ice core now that can test this!)
