Lunar Eclipse on a Perfect Winter Morning #lunar #moon #eclipse #sky

Lunar eclipse from New Mexico 31JAN2018 – moon looks much more orange in picture than it did to my eye

Perfect morning for the lunar eclipse. I could stand at my kitchen sink and watch the moon through a window, then step out on my deck for a view of the whole sky. The morning was clear and calm. As moonlight dimmed, the stars grew brilliant. Then, just at totality, the rising dawn began washing them out again.

I live in the mountains of New Mexico, so once the usual morning breeze kicked up, I hopped back and forth – outside for a better view of the moon’s coppery blush, inside to warm up. Lunar eclipses last long enough for leisurely viewing. There’s time to make coffee and take pictures, even with a simple amateur camera.

The rising dawn won out, and the darkened moon, in the last minutes of totality, faded faster than it set.

Glorious.

Fading bright to dim
Now engulfed in Earth’s shadow
Blushing as you set

Another Successful Science Olympiad – We Play Nerdy #science #citizenscientist #nerdgirl #nerdboy #STEM #education

Crush-testing a tower

Science Olympiad regional at Western New Mexico University is complete and the awards will be handed out shortly at the closing ceremony. I coordinated a middle school event this year, and there was also a high school division. We had great participation from area schools and fine weather.

Congratulations to all the teachers who’ve been coaching their teams for months, to everyone who had to catch a school bus at 5 am to arrive on time, and especially to the competitors. Whether these kids pusue a career in science and technology or not, they’ll be better informed citzens for their interest and knowledge of science and, I think, more interesting people.

Revealed – Truth Is, Zebras Don’t Have Stripes on Skin – is that Weird or Not? #nature #biology #animals #genetics

This may not be the most important piece of news, but zebras are solid black under their striped coat.

 Skin color and hair color are controlled by different genes, hormones, and other factors, says Barsh, who studies the genetics of animal color patterns… citing domestic cats, domestic dogs, horses, zebras, and cheetahs as examples. nationalgeographic

I know that’s true with my llamas. Now, tell the truth. You’re about to go brush the hair backwards on your dog or cat to check, aren’t you? Go ahead! Be a citizen scientist.

Scientific Discovery in Bathtub #science #beetle #bugs #nature

If you’d love to make a scientific discovery, it pays to keep your eyes open.

In 1984, a couple outside of Salem, Oregon, discovered tiny beetles floating in the [bathtub]

water… a species completely new to science. nationalgeographic.com

It also pays to remember Isaac Asimov’s words that “the most exciting phrase to hear in science, the one that heralds new discoveries, is not, ‘Eureka! I’ve found it,’ but, ‘That’s funny!'”

After sending a sample to Oregon State University the couple cleaned the beetles out of their well with chlorine, and I can’t blame them. But Oregon State entomologist Richard Van Driesche read about the beetles and wanted to find more. His parents’ farm is near Salem and when he checked their well water filter, he found several deceased beetles that yielded usable DNA. Oddly enough, the closest relatives to Oregon’s beetles live in a Texas aquifer – a long way for a tiny diving beetle that spends its entire life underground. I’ve seen no word on what they eat down there.

It’s a Scottish Loch – it’s a monster – no, not that one #monster #Scotland #fossil #biology

I understand why we hate to say such a creature no longer swims in Earth’s waters.

Scientists have unveiled a monster that would make Nessie blush: a 13-foot-long reptile that

Various ichthyosaurs

ruled the seas 170 million years ago… the Storr Lochs Monster.”

The ichthyosaur was a predator, a fast marine reptilian that excites our imaginations – and hopes. Sort of a Jurassic dolphin, though not a mammal. Suppose you could discover such a creature – even as a fossil.

An amateur fossil collector … noticed something strange jutting out of the rocks: strings of vertebrae that looked like stacks of chocolate-brown ashtrays.”

Sadly the discoverer died before the fossil was extracted from the very-hard rock matrix that held it. I wonder what he saw when he closed his eyes and imagined his fossil swimming through ancient seas?

I usually think of the cryptid Nessie as more of a serpent – long and thin – that decades of searching has failed to find. Better a fossil in the hand.

The list of missions to Mars – failed and successful – is long, but the list of planned missions is growing longer. Thanks to space.com for the update. You can visit Biosphere 2 in Arizona where environmental studies are ongoing.

Light and Dark Play Role in Life #science #nature #tree #GreatBritian

Humans are diurnal creatures and we carry light into darkness. In my area of New Mexico, where astronomers can still find dark skies, the fight against badly-designed artificial lights is on-going. But, while artificial light can disturb human sleep cycles, it’s generally a good thing for us. That’s not true for all animals. And now a study shows it affects plants, too.

You may know that artificial lights change the behavior of bats and sea turtles, but trees in cities are leafing out earlier thanks to night-time light. Scientists in the UK collected citizen observations of nearly 42,000 individual trees of four species, and satellite data on light intensity. After controlling for temperature and urban heat-trapping, they found three of the tree species budded earlier when exposed to nighttime lights.

It’s not clear whether this change hurts or helps other creatures, but it’s a fascinating study.
