Have you ever gone so fast you were in 0th place.
The mystery of the roaming rocks of Death Valley’s Racetrack Playa may be at an end. Since their discovery in the 1940s, researchers have speculated about what conditions on the playa could cause 15+ kg rocks to slide tens or hundreds of meters across the dry lakebed. But the rare nature of the movement and the remoteness of the location had prevented direct observation of the phenomenon until last December when a research team caught the rocks in motion (see the timelapse animation above or the source video). Winter rain and snow had created a shallow ice-encrusted pond across the playa by the time the researchers arrived to check their previously installed equipment. Late one sunny morning, the melting ice, only millimeters thick, cracked into plates tens of meters wide and began to move under the light breeze (~4-5 m/s). Despite its windowpane-like thickness, the ice pushed GPS-instrumented rocks up to hundreds of meters at speeds of 2-5 m/min. It took just the right mix of conditions—sun, wind, snow, and water—but the two ice-shoving instances the team observed go a long way toward explaining the sailing rocks. (Image credits: R.

Don’t be scared. I’m a shapeshifter too!
The Department of Microscopic Marvels is in awe of the work by photomicrographer Danny Sanchez, who specifically seeks out and photographs precious gems that have been rejected by jewelers because of imperfections known as inclusions. In gemology an inclusion is a characteristic enclosed within the gemstone, which can effect the clarity of the stone, and whose presence can either decrease or sometimes dramatically increase the stone’s value.
For his project, entitled Gemstone Inclusions, Sanches uses his microphotography skills to capture the beauty of these imperfections and provide a glimpse of the fantastic and alien landscapes that exist inside the gems, much too small for our eyes to see unaided. Each a teeny weeny Fortress of Solitude.
Head over to PetaPixel to learn about how Danny Sanchez stages and creates these marvelous photos. Then be sure to visit his own website to get a look at more of his work at a much higher resolution. He has prints available too.

forget howl lets talk about the real Stealer of the Show, spicy mama Prince Justin. how about a little fire scarecrow indeed mmmm
i mentally wrote this post in the shower because i remembered him being a lot cuter but now i realize he looks like anthropomorphic banana pudding. well the lesson here is that we tried. prince justin tried and i think that’s something we can all relate to. sometimes you come out on top and sometimes you’re delicious custard

Is that… is that even healthy?
There are sea organisms and fungi which glow in the dark and there’s fireflies and jellyfish which glow in the dark. It doesn’t do them any harm nor does it do the people around them any harm. I would say its pretty healthy, as well as it would mean more photosynthesis happening in cities which mean cleaner air.
I was just curious about how they were doing it and for some reason I didn’t think to click the link. But thanks! It makes more sense now. I was afraid it was some kind of chemical thing.
nah just genetic modification using existing bioluminescent genes. Genetics is really cool, and so is bioluminescence. I mean they’ve already made pigs glow using jellyfish genes and pigs are waaay more complicated than trees iirc. So they’re actually (i think) less likely to muck it up with trees.
In which case
(I like glowy things)
