"...pretty much all biologists love junk."

Last night, Virginia Tech grad student Ann Hilborn, her labmate Chris Rowe, and their research supervisor Marcella Kelly were posting pictures of animal genitals on their lab’s Twitter account (@Whapavt). When Hilborn added some more from her collection, one of their readers called it a “junk-off”. And thus a hashtag was born. [NSFW?]

Everything you always wanted to know about panda sex

Since the pandas’ arrival, the team at Edinburgh zoo had already tried three times to breed the bears – with considerable fanfare and public attention – and each attempt had ended in disappointment. After a thoroughgoing review of these attempts in late 2014, this year’s season carried with it a sense of added pressure. But the keepers had also come up with one or two new tricks. A few weeks earlier, Maclean had daubed urine from Long Hui, an impressive male panda kept at Schönbrunn zoo, in Vienna, all over Yang Guang and Tian Tian’s enclosures, in order to spice the air with competition and possibility. “She spent a lot of time sniffing and seeing what was going on,” said Maclean. “He came out and was just like, ‘Whoa!’ He was all over the place.”

I .. did not believe there are structures .. that we are not aware of

"In a stunning discovery that overturns decades of textbook teaching, researchers at the University of Virginia School of Medicine have determined that the brain is directly connected to the immune system by vessels previously thought not to exist." While the article at Sciencedaily.com may be a bit breathlessly excited about it, even the more somber source article in Nature agrees that this "may call for a reassessment of basic assumptions in neuroimmunology"

Can evolution explain acts of kindness, and morality? [The Guardian]
We arranged a debate between a sceptical Tom Stoppard and the evolutionary biologist David Sloan Wilson. Stuart Jeffries acted as referee. We arranged for the two to meet recently in the grand boardroom of Wilson’s London publishers to discuss their differences, and reflect on two hard problems – what is the proper scope of science, and what is it to be human.

Charging toward an era of genetically modified humans

The CRISPR Revolution [ungated: 1,2,3] - "Biologists continue to hone their tools for deleting, replacing or otherwise editing DNA and a strategy called CRISPR has quickly become one of the most popular ways to do genome engineering. Utilizing a modified bacterial protein and a RNA that guides it to a specific DNA sequence, the CRISPR system provides unprecedented control over genes in many species, including perhaps humans. This control has allowed many new types of experiments, but also raised questions about what CRISPR can enable." [more inside]

Of true love, AI, and dedicated zookeepers

Chris Crowe has a girlfriend. She stands a leggy 5 feet tall, weighs a trim 11 pounds, and sports a set of wings like you’ve never seen. Walnut the white-naped crane is the most genetically distinct endangered crane on the block — which means she needs to have been making babies, like, yesterday. Walnut was raised by humans at a zoo, and as a result, she recognizes and trusts humans — and is deeply hostile to other cranes. How hostile? She killed the two male cranes that her former keepers attempted to pair with her. "I like to jokingly tell people that Walnut ‘allegedly’ killed two male cranes," Crowe says. "It’s not like she was tried and convicted. We don’t know her side of the story."

Defending Darwin

I’m occasionally told my life would be easier if I backed off from my relentless efforts to advance evolution education. Maybe so. But to shy away from emphasizing evolutionary biology is to fail as a biology teacher. I continue to teach biology as I do, because biology makes sense only in the light of evolution.

There's something fishy about fish oil

Fish oil: it's been touted as a solution to heart health, dementia, glaucoma, and a host of other ailments. Unfortunately, it turns out that most of the evidence for its benefits is equivocal at best. And it turns out that fish oil isn't particularly useful for our pets, either. Worse, it turns out that the foundational study that kicked off interest in fish oil as a supplement is not quite as promising for fish oils as it is usually construed and cited. Given that fish oil can induce strokes in high quantities (and may interfere with treatments like chemotherapy), is poorly regulated, and is expensive, should we be promoting fish oil supplements as strongly as we do?

Model organisms in the wild: beyond the laboratory

In biology, model organisms are the workhorse species in which most biological science gets done: fruit flies (D. melanogaster), house mice (M. musculus), shale cress (A. thaliana), zebra fish (D. rerio), nematodes (C. elegans), yeast (S. cerevisiae), and bacteria (E. coli.) They are science's heavy hitters... in the lab. But most scientists know almost nothing about how these species behave in the wild, outside of the context of humans. ELife's new series on the natural history of model species aims to change that. So far, they have published on the natural history of zebra fish, E. coli, and nematodes, with more to follow.

Orchids underground: a beautiful parasite

In 1928, a farmer digging in his garden found a flower blooming underground. Three years ago, scientists discovered that it's so well adapted to living underground that it has lost almost all of its chloroplast genes. While this species is unusual for an orchid in the extent of its parasitism, it turns out that all orchids are actually parasites--stealing nitrogen from tiny fungi in the soil without trading any carbon back as plants usually do. See photos of the underground orchid here.

Saving species is essentially a forever-type problem.

If other horses are the equivalent of feral dogs, then the Przewalski’s horse is a wolf. In its native Mongolia, where it goes by the name takhi, it is known as the father of horses. Mongolians regard the takhi as spiritual, holy animals, and for millennia they largely left them alone... The trouble all began in the late 19th century, when the Western world finally took note of the takhi. Nikolai Przewalski, a Polish-born explorer serving as a colonel in the Russian army, “discovered” the horses during an 1878 expedition to the Mongolian-Chinese frontier. Naturally, Przewalski named the horse after himself, and when he returned to the West, word quickly spread among zoos, adventurers, and curio collectors about the mysterious wild horses.

Why don't rodents vomit?

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.

Get ready to rumble, if you are furry and nurse your offspring.

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.

I also check my skeletons twice. You can never be too careful.

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.

She spoke: Males have one fewer pair of ribs than females.
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.

If we're not in pain, we're not alive

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 Dumbspeech State of Grace Echopraxia [website], the long-delayed "sidequel" depicting parallel events on Earth.
