Impressive. Is that copper?

My guess--considering the mildly acidic environment inside the human mouth--that copper is NOT likely. It would be like having a older copper penny in your mouth all the time.

More probable is gold mixed with something to give it strength, at most 14 karats in purity.

And of course they used a spacey sounding synth voice. Let's hear the same thing done on distorted electric guitar. Or drums.

Technically it ain't an image, but this version of Scientific American's 60 Second Science had some nice audio images.

To be sure, the podcast begins a 30 second commercial, but do yourself a favor and listen. While the link includes a transcript of the podcast, that doesn't fully convey the enthusiam of researcher Bray (for whom I would WANT to be a very good puppy).

Video drone catches a herd of 15 elephants napping.

In Chinese with English subtitles.

Authorities in Yunnan province in southwestern China have been tracking this herd. The drone over the sleeping elephants was stationed at over a thousand feet in order to not disturb them.

Interesting. I thought they were like horses and sleep standing up.

Me too.

PERHAPS these elephants--who live in human-infested areas--have learned that they could go to the trouble of lying down because they mostly (entirely?) lack active predators (well, except for humans), unlike their brethren living further south in Asia or in Africa.

Maybe elephants in zoos lie down? Or probably they can hear/smell/see nearby predators so they don't take the chance.

Looking it up I see that horses do lay down to get REM sleep, but they only need a short time of it--and one of the herd will stand lookout.
I suspect elephants can do some sleeping standing as well, but likely need to lay down to get some good REM type sleep.
I've seen a rhino at the Bronx zoo sleeping laying down.
Best part: before getting up it made a huge fart--which disturbed the hay-dust on the ground so it looked like a big fart cloud.

Heh.

Long ago I had taken some of my sister's friends from Germany to the San Diego Zoo (they specifically wanted to go there). There we got to see a hippo standing inside his enclosure. He lifted his tail nearly straight up and let out a massive fart which we could hear THEN smell only seconds later (we might have happened to be downwind). It was...unpleasant.

This landed on my hand yesterday. It startled me and it flew to the gate. I was able to grab my phone and take a few pics. I don't know if i'm more amazed at the dragonfly or that i actually took a great pic.

Good call, what you've got their is a 12 spotted skimmer. Also for the future references the easiest way to tell if it is indeed a dragonfly is to look at the wings. If the wings are like in your photo it is a dragon fly, if the wings are folded up against another it is not a dragon fly but a damsel fly.

I think most adults can tell just by the size of the insect alone (damsel fly being dwarfs in comparison). The above is a useful thing to tell your younger children if you go out for a hike and you see them flying around. It's a teachable moment and every time they see one they will likely chime in with much excitement if it is one or not. ;)

justine, you may check with your local science museum and see if they want a copy of your pic (which is EXCELLENT).

There is a recently started local (around LA) project where our equivalent museums are asking for such pics of local flora and fauna.

This color-enhanced picture, originally taken by NASA’s Magellan spacecraft, shows part of Alpha Regio, a tessera on Venus. Tesserae are extremely distressed areas of terrain that may be the oldest regions of the Venusian surface, having survived a period of extreme volcanic activity that re-surfaced the rest of the planet. DAVINCI+, one of NASA’s two new Discovery-class missions to Venus, will study Alpha Regio to test the hypothesis that the tessera plateaus are analogs of Earth’s continents, one of the many intriguing questions this pair of missions will seek to answer.

[snip]

After some thought it almost certainly was NOT INTO that volcano.

That meteor track was several dozens of miles UP, many times higher than any mountain, and probably was moving closer to parallel to the ground AWAY from the photographer and the volcano. Had the lucky photographer been just a few miles to one side or the other the track would have looked like it "hit" the side of the summit.

But it was a neat-looking coincidence.
