A few years ago, it occurred to a few scientists that neither mice or rats are capable of vomiting. What about other rodents? It turns out that being unable to vomit is a trait common to all rodents, not just mice and rats. Interests piqued, the researchers set out to find out why.
That's right - it's time for Mammal March Madness! "Battle outcome is a function of the two species' attributes within the battle environment. Attributes considered in calculating battle outcome include temperament, weaponry, armor, body mass, fight style, and other fun facts that are relevant to the outcome. These are one on one- head to head combat situations- um except for the mythical mammals that have multiple heads. Some random error has been introduced into calculating battle outcome & the amount of that error is scaled to the disparity in rankings between combatants. Early rounds, the battle occurs in the better-ranked species' habitat (home court advantage). BUT once we get to the ELITE EIGHT, battle location will be random: forest, semi-arid desert, intertidal zone, or snowy tundra." Action kicks off on March 9 with the wildcard match up between the pygmy jerboa and the bumblebee bat (Kitti's Hognosed Bat). You can follow the action on twitter using the hashtag #2015MMM or on the blog Mammals Suck. In the meantime, start filling out your brackets - common names or binomial nomenclature.
Troubles in Paradise is a review of the history and arguments of the creationism/intelligent design movement, written by James Downard.
We're beginning to understand the genes behind how men lost their dick spines. In fact, smooth penises are a derived state in humans; many if not most mammals have some level of spikiness or roughness on the penile tissue. We've known that chimps have penile spines since 1944! However, no one's really quite sure exactly why humans lost their spines. [more inside]
What pushes scientists to lie? The disturbing but familiar story of Haruko Obokata. The spectacular fall of the Japanese scientist who claimed to have triggered stem cell abilities in regular body cells is not uncommon in the scientific community. The culprit: carelessness and hubris in the drive to make a historic discovery.

"A remarkable international effort to map out the avian tree of life has revealed how birds evolved after the mass extinction that wiped out the dinosaurs into more than 10,000 species alive today. More than 200 scientists in 20 countries joined forces to create the evolutionary tree, which reveals how birds gained their colourful feathers, lost their teeth, and learned to sing songs." Via iO9.

I waited silently for her to explain that the female pelvis is shaped slightly differently from the male’s, with a larger opening for childbearing. That part was the giveaway. The real purpose of the exercise was to make her prove her conjecture with measurements--to translate the theory to practice. I also wanted her to explain why this sexual dimorphism--that is, this sexually determined physical difference--is not nearly so pronounced in nonhuman primates, such as chimpanzees.When teacher Robert S. Root-Bernstein got this answer to his question on how you should distinguish between male and female skeletons, he had to find a way to make her realise her error without disparaging her religion.
She spoke: Males have one fewer pair of ribs than females.

The assumption that synthetic biology makes it easy for anybody to “engineer biology” is not true. The underlying vision holds that well-characterized biological parts can be easily obtained from open-source online registries and then assembled, by people with no specialist training outside professional scientific institutions, into genetic circuits, devices and systems that will reliably perform desired functions in live organisms. This vision, however, does not even reflect current realities in academic or commercial science laboratories

You invest so much in it, don't you? It's what elevates you above the beasts of the field, it's what makes you special. Homo sapiens, you call yourself. Wise Man. Do you even know what it is, this consciousness you cite in your own exaltation? Do you even know what it's for?Dr. Peter Watts is no stranger to MetaFilter. But look past his sardonic nuptials, heartbreaking eulogies, and agonizing run-ins with fascists (and fasciitis) and you'll find one of the most brilliant, compelling, and disquieting science fiction authors at work today. A marine biologist skilled at deep background research, his acclaimed 2006 novel Blindsight [full text] -- a cerebral "first contact" tale led by a diverse crew of bleeding-edge post-humans -- is diamond-hard and deeply horrifying, wringing profound existential dread from such abstruse concepts as the Chinese Room, the Philosophical Zombie, Chernoff faces, and the myriad quirks and blind spots that haunt the human mind. But Blindsight's last, shattering insight is not the end of the story -- along with crew/ship/"Firefall" notes, a blackly funny in-universe lecture on resurrecting sociopathic vampirism (PDF - prev.), and a rigorously-cited (and spoiler-laden) reference section, tomorrow will see the release of

"... a series of curated, open access books about life — with life understood both philosophically and biologically — which provide a bridge between the humanities and the sciences." Although they offer "frozen PDFs," these books—on topics like biosemiotics, animal experience, and air—are curated collections of links to open access science articles, reviews, interviews, podcasts, sometimes with embedded sounds and videos. They have ISBN numbers and editors vetted by the Open Humanities Press, which is generally a gold mine of interesting books and journals. They feel perfectly at home on the open internet, evoking hope and nostalgia for a flourishing academic world wide web, without paywalls and login screens. [more inside]

'Protein Packing' strives to more accurately depict the molecular chaos in each and every cell, with proteins jittering around in what may seem like random motion. Proteins occupy roughly 40% of the cytoplasm, creating an environment that risks unintentional interaction and aggregation. Via diffusion and motor protein transport, these molecules are directed to sites where they are needed.
