Here's an incredibly cool video showing the prow of a massive ice breaking ship as it plows through Antarctica's Ross Sea. The footage is sped up, to pack two months of travel into five minutes. But, unlike a lot of time-lapse videos, this one also has a really informative audio track, in which marine scientist Cassandra Brooks waxes poetic about the many different kinds of ice and explains why she and her team were out there, breaking through the stuff, to begin with.
Bonus: At the end, you get to see the absolute adorableness that is penguins on high-speed fast forward.
Over at Fast Company, our pal Chris Arkenberg wrote about how advances in synthetic biology and biomimicry could someday transform how we build our built environments:
Innovations emerging across the disciplines of additive manufacturing, synthetic biology, swarm robotics, and architecture suggest a future scenario when buildings may be designed using libraries of biological templates and constructed with biosynthetic materials able to sense and adapt to their conditions. Construction itself may be handled by bacterial printers and swarms of mechanical assemblers.
Tools like Project Cyborg make possible a deeper exploration of biomimicry through the precise manipulation of matter. David Benjamin and his Columbia Living Architecture Lab explore ways to integrate biology into architecture. Their recent work investigates bacterial manufacturing--the genetic modification of bacteria to create durable materials. Envisioning a future where bacterial colonies are designed to print novel materials at scale, they see buildings wrapped in seamless, responsive, bio-electronic envelopes.
Trouble is, a lot of information about living things is hidden behind paywalls or scattered across random sources where the general public can’t easily get to it. That’s where you come in! Help fill the Encyclopedia of Life’s open-source database with information about animals, plants, fungi, protozoa, and bacteria.
Ocellated icefish live deep underwater in the cold oceans surrounding the Poles. They have clear blood. If you remember your childhood biology classes, you should remember that this kind of makes no sense. After all, blood is red because of hemoglobin — the iron-rich protein that carries oxygen around in your blood stream. No hemoglobin, no oxygen. No oxygen, dead fishies. Right? Popular Science explains how ocellated icefish get around this little conundrum. — Maggie
At Double X Science, Jenny Morber has an excellent piece about the wide range of diversity seen in human lady parts. "Are you normal? Yes. Are you average? No. Most likely," she writes. What follows is a fascinating tour of human biology, from the different lengths and colors of labia to the wide range of shapes exhibited by the inside of the vaginal canal, itself. Even better, all of this can change over the course of an individual woman's life, rendering "average" even more meaningless. — Maggie
If you think about lactation too hard, it starts to seem a little strange — like the biological equivalent of saying the word "that" over and over until it's just a weird sound you're making. But, writes Nicholas Day at Slate, the sort of existential weirdness of breast milk is nothing compared to what's going on in the stuff at a chemical level. For instance, breast milk contains sugars that aren't actually digestible by human infants. That's because they aren't meant for the infant, itself. Rather, your breast milk is helpfully feeding your baby's intestinal bacteria. Freakier still: In monkeys, the chemical composition of breast milk can change, depending on factors like your baby's sex and whether your baby is showing signs of illness. — Maggie
Another great ramble from the always-fascinating Venkatesh Rao entitled "The Dead-Curious Cat and the Joyless Immortal," considers several explanations for our species' curiosity, and asks whether our weird, ubiquitous artificial life-forms (corporations) share this trait, and why:
Alone among the curious animals (though this seems like a conceit that more research might invalidate), we seem to be curious about clearly useless things. Or at least, things that have no obvious and immediate use. Humans seem to frequently poke at things that yield returns, if at all, only generations later. And often in ways unsuspected by those who do the poking.
We stare at the stars, we peer through microscopes, we climb mountains and we dive to the ocean floor.
This behavior, so natural to humans, is incomprehensible to human organizations. So things like space programs or other pure curiosity driven efforts have to be justified by politicians on the basis of “will improve life here on earth through the discovery of new materials and advances in medicine.” This is probably the mother of all idiotic fictions. Fortunately, we don’t seem to require our institutional fictions to be credible. Merely sufficient to stop conversations we don’t want to have.
There is an interesting symmetry here. Organizations naturally try to avoid pain — the pain of business model obsolescence or national decline for instance – through institutionalized “curiosity.” They find joy-seeking unnatural and in need of justification (hence the paradoxical notions of “efficient” innovation with high “yield” or “impact” and the relentless war on waste).
This has even been turned into a depressingly banal formula for innovation: what pain are you seeking to relieve?
For humans the reverse is true. Curiosity driven by pain-aversion is unnatural, but curiosity driven by joy-seeking is natural and requires no further explanation. Efficiency is the last thing on our minds when we are being curious. The concept does not even apply: efficiency pre-supposes a goal. Waste is pain in the efficient pursuit of goals.
Say you're a marine biologist and you want to study the little bitty creatures of the sea — shrimps and worms and things like that. How do you go about capturing them?
Why, with an underwater vacuum, of course.
At the PNAS First Look blog, David Harris writes that this "SCUBA-tank powered vacuum, called an “airlift,” inhales shrimp, sand fleas, marine worms, and 'things that would swim away if they had the chance.'"
"The earliest sawfishes likely arose in the shallow Tethys Sea, that ocean surrounded by the ancient continents of Godwanda and Laurasia, during the Cretaceous period at least 60 million years ago," writes Dr. M. at Deep Sea News.
These "sole survivors of an ancient bloodline" now number only seven species which roam the muddy bottoms of coastal areas, bays and estuaries.
All sawfishes can move easily between fresh and saltwater and often venture deep upstream into rivers. The sawfish lifestyle puts this both their size and saw near humans. All seven species are considered critically endangered by the IUCN. As much as we have impacted them, sawfish have also greatly influenced our culture.
And now, they're one of the most threatened species on our planet. Thanks, humans!
Thanks to Jurassic Park, we tend to focus on one use for the DNA of extinct creatures — resurrecting them, in full, to live here in the modern age. But it's not necessary to go that far to learn a lot about those animals, and the evolution of life, in general. At the Experimental Podcast, Stephanie Vogt talks about the paleophysiologists who are reconstructing the proteins of extinct animals using fragments of DNA found in long-dead remains. Those proteins, simple as they may seem, hold some amazing stories. For instance, reconstructed haemoglobin from wooly mammoths could someday help doctors get oxygen to the brains of high-risk human surgery patients. — Maggie
On the left is a picture of me with my bike, taken by my friend Laura Kling. On the right is the same image, as it would be seen by a person with protanopia — a relatively common (as in, still very rare) form of color blindness that affects the ability to see green, yellow, and red colors.
On the Vintage Ads LJ group, the awesome Man Writing Slash has rounded up a series of old ads that use mechanical methaphors for the human body.
One of my favorite ad tropes is the Body=Machine/Body=Factory idea, because the imagery is often more detailed and also more hilarious than in most ads. As a kid I used to LOVE any illustrations of the body that depicted tiny workers inside, such as The Human Body, for example. :D This link to a book about Fritz Kahn's Der Mensch als Industriepalast is also fascinating (although not advertisement). Brief video version of that book HERE (well worth 3 minutes of your time.) This series of articles and illustrations in the same vein (XD) appeared in the Berliner Morgenpost in 1931 and is simply breathtaking.
