Are you interested in plants? The Royal Botanic Gardens at Kew aren’t just a tourist attraction -- they also run one of the world's leading botanical research institutes. To show off how important and fascinating modern plant science can be, they've commissioned a series of snazzy short videos to showcase their work. Start with the award-winning Forgotten Home of Coffee (6:00) (based on this worrying Kew study from 2012), then come back for the rest. [more inside]

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.
A team of researchers, including University of Edinburgh paleontologist Stephen Brusatte and Swarthmore College Associate Professor of Statistics Steve C. Wang, cataloging 853 skeletal characteristics in 150 dinosaurs and analyzing the rate at which these characters change, and they found that "there was no grand jump between nonbirds and birds in morphospace." In other words, birds didn't suddenly come into existence, but evolved, bit by bit, or characteristic by characteristic. But when birds were finally a thing, they went crazy. "Once it came together fully, it unlocked great evolutionary potential that allowed birds to evolve at a super-charged rate."

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
Your body is home to about 100 trillion bacteria and other microbes, collectively known as your microbiome. Naturalists first became aware of our invisible lodgers in the 1600s, but it wasn’t until the past few years that we’ve become really familiar with them. This recent research has given the microbiome a cuddly kind of fame. We’ve come to appreciate how beneficial our microbes are — breaking down our food, fighting off infections and nurturing our immune system. It’s a lovely, invisible garden we should be tending for our own well-being. But in the journal Bioessays, a team of scientists has raised a creepier possibility. Perhaps our menagerie of germs is also influencing our behavior in order to advance its own evolutionary success — giving us cravings for certain foods, for example.[more inside]

With growing fascination for the large land vertebratomorphs that are so startlingly diverse on Tatooine, I secured Imperial funding for an expedition to Tatooine, to survey the exotic megafauna and search for fossils of Tyrannodraconis that might further illuminate their evolution.

Some people stick with the traditional, feeling struck by the epic beauty or blown away by the insane scale of the universe. Personally, I go for the old “existential meltdown followed by acting weird for the next half hour.” But everyone feels something. Physicist Enrico Fermi felt something too—”Where is everybody?” It turns out that when it comes to the fate of humankind, this question is very important. Depending on where The Great Filter occurs, we’re left with three possible realities: We’re rare, we’re first, or we’re fucked.

Evolutionary biologists at Northumbria University have used science to figure out "attractive human dance moves" that demonstrate optimum genotypic and phenotypic health to prospective mates. "Cutting-edge motion capture technology" was used to record good and bad dancing. (Technoviking was reportedly unpleased.)

"Now, I don't write many short stories these days, but I'm a sucker for the right kind of charity approach. And besides, I had a hypothesis I wanted to test: that every short story can be improved by adding dinosaurs and sodomy."

This 419-Million-Year-Old Fish Has the World’s Oldest Known Face What makes it remarkable is everything that’s come after it: It’s the oldest known creature with a face, and may have given rise to virtually all the faces that have followed in the hundreds of millions of years since, including our own.
In March 2012, inspectors from the U.S. Department of Agriculture uncovered a problem in Elgin, Texas. Beef sausage from a small family-run meat processor appeared to have been contaminated with a nasty bacterium called Listeria monocytogenes. The bug can make people sick and, in rare cases, be deadly. The processor had to recall more than a ton of sausage. It’s the kind of story that strikes terror in the hearts of other sausage peddlers, including Mike Satzow, so he uses phages to keep his small company's sausages safe to eat.

"The majority of fossil discoveries worth publishing about can either strengthen previous studies or dish out little parcels of new data. These allow us to slowly piece together the history of life on Earth, but do not significantly rock the boat. But every now and then you are confronted with a jaw-dropping specimen, a fossil that says, “forget the textbooks, THIS is how it happened…” Momentous discoveries like Lucy the Australopithecus and the first batch of Chinese feathered dinosaurs that unleashed a tsunami of new information, bringing sudden clarity to our view of the distant past, and forcing us to rethink what we thought we knew about evolution. Now joining their ranks is a little armoured fish called Entelognathus, described in Nature by an international team of researchers led by Prof. Zhu Min at IVPP, Beijing." [more inside]
The Year Of Wallace (who wasn't Darwin) is pretty well-covered on MeFi. But there's news, history keeps evolving: First, a 17-year-old pupil rediscovered Wallace's butterfly collection at the Oxford University Museum.

What, really, is a wolf-dog?? Wolf-dogs already blur the line between dog and wolf - BUT things get really muddy if dogs are proven to have evolved themselves : "The evolutionarily correct way to state all this is that human beings, with their campfires and garbage heaps and hunting practices, but above all with their social interactions, represented an ecological niche ripe for exploitation by wolves."
Selfish traits not favoured by evolution, study shows "Evolution does not favour selfish people, according to new research. This challenges a previous theory which suggested it was preferable to put yourself first. Instead, it pays to be co-operative, shown in a model of "the prisoner's dilemma", a scenario of game theory - the study of strategic decision-making. Published in Nature Communications, the team says their work shows that exhibiting only selfish traits would have made us become extinct. "
Are human beings the descendants of chimpanzee/pig hybrids? This radical theory might seem easy to disprove, but "decent arguments against the hybrid origins theory are surprisingly hard to find."
The results of the Cambrian explosion are well documented in the fossil record, but its cause -- why and when it happened, and perhaps why nothing similar has happened since -- has been a mystery. Now a recent paper in Nature (abstract) suggests that the answer may lie in a second geological curiosity -- a dramatic boundary, known as the Great Unconformity, between ancient igneous and metamorphic rocks and younger sediments.
