Photo Release: Hubble observes energetic lightshow at Saturn’s north pole

Astronomers using the NASA/ESA Hubble Space telescope have taken a series of spectacular images featuring the fluttering auroras at the north pole of Saturn. The observations were taken in ultraviolet light and the resulting images provide astronomers with the most comprehensive picture so far of Saturn’s northern aurora.

An asteroid redirected bird evolution

When an asteroid hit Earth 66 million years ago, it helped wipe out all the dinosaur lineages save one: the birds. But birds didn’t completely dodge the cataclysm the asteroid triggered. Recent research suggests that forests around the planet were devastated. With forests gone, bird species that called trees home went extinct alongside their nonavian dinosaur cousins. This means that the birds that we see living in trees today evolved from lineages that, in the aftermath of the impact, were ground-dwelling.

I’m an exceptional sleeper. I count it among my super powers. And since we’re among scientists, here’s the quantitative evidence: My Fitbit once registered my sleep efficiency as 100%. I stopped tracking after that since I wasn’t convinced that 100% sleep efficiency was something anyone should aspire to.

The American Soul (and yours and mine): Closer to King-of-the-Hill? Or the Herndon Climb? And where do meteorologists fit in?

Okay, okay. So it’s a long title.

Today’s LOTRW post is the product of insomnia (writing started around 2 am). A lot of Americans are tossing and turning instead of sleeping well these days. This week’s death of Senator-and-American-naval-hero John McCain has occasioned a near-universal sense of loss and soul-searching.

Sometimes soul-searching can use a bit of a frame. Here’s one.

Wikipedia has this to say about King-of-the-Hill. a children’s game, the object of which is to stay on top of a large hill or pile (or any other designated area) as the “King of the Hill”. Other players attempt to knock the current King off the pile and take their place, thus becoming the new King of the Hill.

The way the “king” can be removed from the hill depends largely [largely? Only largely?] on the rules determined by the players before the game starts. Ordinarily pushing is the most common way of removing the king from the hill, but there are significantly rougher variations where punching or kicking is allowed. As such, the game is often banned from schools.
