Exciting times in astronomy and astrophysics:

Electromagnetic and gravitational waves observed together for the first time, from a nova* called GW170817 caused by the collision of two neutron stars. More. Among other really cool results, a demonstration that as Einstein predicted gravitational waves travel at the speed of light.

Half of the mass of the universe, previously missing, has been found hiding between the seat cushions. More. This is the ordinary ("baryonic") matter we know about and are -- we were pretty sure it had to be somewhere, based on models of the universe, but couldn't see it because it's not hot (i.e., inside stars) and so isn't bright -- as opposed to the still-unobserved "dark matter" that we think is causing other, weirder effects. (via)

New hypothesis about knots in the early universe suggests that they provide an answer to both why the universe is three dimensional (knots can only form in 3D spaces -- they can be unraveled in higher dimensional spaces) and what powered the early inflationary universe. (via)

Why shoelaces eventually come undone. Short answer: when your foot comes down, the sudden stop tugs a very tiny bit on the free ends of the bow, and the tiny tugs build up. (via)

A solar-powered device that condenses water out of low-humidity air. Mind you, that 20% humidity is pretty moist for a desert: our evaporative cooler works effectively only below that, which is most of the time outside of rainy season. Good stuff anyway.

There is heat below the surface of Enceladus. (via)

I really want a Finnish-speaker's opinion on what it's like to read The Song of Hiawatha in Finnish. (Did the translator use the Kalevala meter that Longfellow was imitating, or did they imitate the imitation? And what would THAT sound like?)

On June 20-21, Icelandic state television RÚV did a 24-hour live broadcast of a drive on the Ring Road, all the way around Iceland, to the soundtrack of a procedurally generated 24 hour remix of Sigur Rós's "Óveður." I caught parts of this livestreamed online, and had fun recognizing places I've been. The recording is finally up on the band's website: "Route One" Content warning: hypnotic Icelandic landscapes.
