Terraforming

It turns out that a large number of crannogs, manmade islands in Scottish lochs made by basically piling rocks in the water until you have stacked enough of them atop the pile to stick up out of the lake, date back further than expected. Given that doing amazing things with big rocks was something of a national pastime in Neolithic Britain, this is less surprising to me than it probably should be. . [Author: Tam]

Gaia has a pet rock.

It's not a moon, because it orbits the sun, not the earth. Well, sort of. Its orbit around the sun kind of oscillates around the earth, hence its name: , which is apparently Hawaiian for something along the lines of 'oscillating celestial object'. There are questions about its origin, whether it's a rogue asteroid that's been swept up in our gravitational orbit or what. The current prevalent theory is that it's an actual chunk of the moon knocked loose in a giant cosmic fender bender, and is ...

Sharper than Sharp

A phrase I'd heard and had found myself repeating uncritically was that regarding high-megapixel camera sensors "out-resolving" the lenses that were on them. It came to mind again recently when I saw stuff like this. That Six-Four Impala was shot with a 36MP Nikon D800 using a mid-'90s vintage Nikon 35-105mm f/3.5-4.5 AF-D lens. At first glance, it looks okay, but blow up to full screen or (worse) start pixel peeping at 100% magnification and something's...off. The lines of the car have a bi...

Gibraltar Falls

Anyone who's read a bunch of Poul Anderson's "Time Patrol" stories (there's an omnibus collection, by the way) will remember the setting of "Gibraltar Falls". Apparently there are some new discoveries of sediments left from both the ancient salt flats and the flood that covered them. "The serene turquoise waters of the Mediterranean Sea hide a sharp-tasting secret: a layer of salt up to two miles thick, lurking deep underneath the basin. The ghostly white minerals are one of the few traces of ...

Mindbending

I don't know if you saw Bobbi's little tensegrity structure yesterday, but it's available on Amazon. Build it yourself in a few minutes before your morning internetting! Amaze your friends! (There are more expensive and elaborate tensegrity projects, like this plant stand, but it doesn't appear very compatible with cats.) My hasty photo is not as good as Bobbi's because of depth-of-field issues. I should have used a bounced flash rather than trusting a large aperture. Even with a smallish 1...

Migrant Invasion

If you're in to dawn-of-civilization type history, this find from Spain is pretty interesting."Beginning in the Bronze Age, the genetic makeup of the area changed dramatically. Starting in about 2,500 B.C., genes associated with people from the steppes near the Black and Caspian seas, in what is now Russia, can be detected in the Iberin gene pool. And from about 2,500 B.C. much of the population’s DNA was replaced with that of steppe people. The “Steppe Hypothesis” holds that this group spread e...

Equinox

The TeeWee weatherpeople have been talking about "meteorological spring" since the first of the month, but real actual spring begins today, with the vernal equinox. Today, the sun will be in the sky for exactly...well, a little more than half the day, actually.  It's complicated. What with Indy being about as far west as you can go in the Eastern Time Zone, the sun sets at around 8PM now, and sunset just gets later and later from here, to my delight and Bobbi's chagrin. .

Mars Needs Mic Mittens

That skycrane lowering the rover from a near hover and then blasting away on its thrusters is pretty epic, and took a lot of engineering confidence. Used also with the Curiosity rover, it's lot showier than bumping down in a ball of airbags like earlier efforts.

More Human Than Human

I don't know how much of this is hyperbole and how much is actually yikes-worthy: It is not clear how far Chinese military researchers have gone. They are, however, advocating use of the CRISPR gene-editing tool to enhance human capabilities, and the Communist Party's Central Military Commission is "supporting research in human performance enhancement and 'new concept' biotechnology." I mean, maybe they just want people for an exciting new life in the off-world colonies? . [Author: Tam]

How things work.

At this link, you can find a neat site that explains how camera sensors and lens optics work together to make pictures. It's very informative, starting from first principles, and there are lots of sliders to manipulate for a very hands-on learning experience. Like a quality children's museum except for grownups and you don't have to worry about snotty little fingers having been all over everything. Definitely some first rate edutainment. . [Author: Tam]

Dinosaur Poopers

That's not a metaphor for politicians. We're talking actual fossilized dinosaur poopers. "The world’s oldest known all-purpose orifice sits in a fossil display case in the Senckenberg Natural History Museum in Frankfurt, Germany, so close to the glass that enshrines it that you can “put your face up to it, like this,” said Jakob Vinther, a paleontologist at the University of Bristol in England, holding his hand a couple inches from his nose."

"Spinning Buzzsaw of Death!"

The hype the Black Talon generated back in the day was completely disproportionate to its actual utility as a bullet. They were good for the time, one of the first modern designs of the post-Miami gunfight era, but people absolutely lost their minds over the black Lubaloy coating, the pointy jacket petals, and of course that bellicose name.Of the original loadings, 147gr 9x19mm, 180gr .40S&W, and 230gr .45AARP, the .45 is the only one that still maintains some relevance. The 9 and .40 were almos...

This is where we start gene splicing, right?

 Permafrost is becoming a lot less perma in many areas of the arctic, which has already led to the discovery of some well-preserved wooly mammoths. Now the thawing of long-frozen ground has unearthed a couple of well-preserved cave bear carcasses.This has allowed the species, which was formerly known only from fossils, coprolites, and steamy historical romance novels, to be seen in the flesh for the first time.Like anyone who's read a Crichton novel, my first thought was to hope that someone was...

Mariprofundis R'lyehianum

Just in case extracting the DNA of the ancestor of bubonic plague from the teeth of neolithic skulls doesn't trigger the final boss fight of 2020 A.D., scientists are also feeding nutrients to dormant hundred-million-year-old bacteria from the benthic mud of the abyssal plains of the ocean to wake them up and see what happens.via GIPHYThere is no way that HLV2514 is going to get here in time. .

Put that back where you found it. Right now.

"Scientists and archaeologists now believe, however, that the plague bacteria, which caused the medieval Black Death that killed up to half of Europe’s population, infected humans roughly 5,000 years ago in the Stone Age. The bacteria, after it had entered the bloodstream and likely killed the host, circulated into the pulp chamber of teeth, which kept its DNA insulated from millennia of environmental wear and tear. In the past decade, scientists have been able to extract and analyze that DNA.Th...
