The Carnal Carnival comes again

Based on a careful analysis of D&T visitors over the past month, I conclude that orgasms are a popular topic.

Absolute unique visitors per day, tabulated by Google Analytics..

So perhaps you folks would be interested in an entire blog carnival about orgasms? I think this is very likely. Fortunately for you, orgasm is the theme of this month’s Carnal Carnival, hosted with great enthusiasm by Scicurious. Enjoy!

Science online, sociable tortoises edition

Hey, there! Photo by hankplank.

“Sociable tortoises” would make a pretty good name for a band. I assume they’d be somewhere in the genre phenotype space between Vampire Weekend and The Decemberists.

  • Call it the “smugness threshold.” Higher income is only associated with greater emotional well-being up to a point—but past that point, people with higher incomes still report greater perceived happiness. (Neurotic Physiology)
  • Heads up! Tortoises follow the gaze of other tortoises, indicating unexpected social intelligence. (The Thoughtful Animal)
  • Who knows what a fish is thinking? Siamese fighting fish will famously attack other fish or their own mirror images with equal vigor—but their brains express different genes when looking at their own images! (NeuroDojo)
  • Best paleontological reconstruction illustration ever. Pterosaurs may have launched into the air by “vaulting” on their arms, not jumping with their teeny-tiny legs. (80 Beats)
  • Phylogenies on the witness stand. Ed Yong surveys the use of evolutionary trees as evidence in legal cases. (Not Exactly Rocket Science)
  • Can’t wait to see the phylogeny of the Septuagint. Texts, especially hand-copied manuscripts, mutate over time in much the same way as DNA. (The Atlantic)
  • Especially in Hitchcock’s classic “To Catch a Prairie Dog.” Film scores contain sound patterns strikingly similar to animal alarm calls. (Wired Science; original article at Biology Letters)
  • We are also the beaver. New analysis of fossils identifies the sister group to Castor, the genus containing modern beavers. (Open Source Paleontologist; original article on PLoS ONE; interview with one of the authors)
  • That’s what undergrad field assistants are for. A classic study of bitter taste as predator deterrent had students taste-testing tadpoles. (Wonderland)

Apparently trying to top the transcendent union of “Star Trek” and Monty Python, the Internet presents Harry Potter singing Tom Lehrer. I’ll admit, this upgraded my opinion of Daniel Radcliffe from “Hollywood nerd” to “nerd.”

Science online, oily coral edition

  • Is anyone really surprised? Biologists working with NOAA have found the first clear evidence that the Gulf of Mexico oil spill is damaging coral reefs. (Deep Sea News)
  • Drink the corn liquor, let the Ritalin be. Could Ritalin help fight cocaine addiction? (Neurotic Physiology)
  • Trade-offs are a bitch. Adaptation for swimming and seal-hunting has made the polar bear’s skull structurally weaker than those of its closest relatives. (Not Exactly Rocket Science)
  • Admixture is fun! Razib Khan examines genetic studies of major human ethnic groups. (Gene Expression)
  • Gotta get funded to do the science. Over at dechronization, Rich Glor lays out tips on writing a doctoral dissertation improvement grant. (Part 1, Part 2, Part 3, Part 4 Part 5)
  • Scientific support for the siesta. A daytime nap can improve memory performance. (BrainBlogger)
  • Hint, hint. Submissions for the Open Lab 2010 collection of online science writing close at the end of the month. (The Thoughtful Animal)
  • This just in. Eating fewer calories than you burn results in weight loss—even when most of those calories are in Twinkies. (Weighty Matters)
  • Because you can’t develop Seasonal Affective Disorder if your brain is too small. Lemur species that live in habitats with greater seasonal changes have larger brains. (NeuroDojo)
  • Paging Dr. Pangloss. Psychologists are surprised to discover that the sight of cooked meat makes men less aggressive. They will no doubt also be surprised to find that it makes men ask for a fork and A-1 Sauce, too. (AOL News, McGill University press release)
  • Science is impossible. But that’s okay. Really. (We, Beasties)

Science online, miracle cure edition

  • Or, you know, the evolution of a super-cold. The discovery of a new way to stop viruses after they’ve already invaded cells could lead to an actual cure for the common cold. (The Independent)
  • Pleistocene Park, anyone? An extremely well-preserved mammoth skeleton unearthed near Denver, Colorado, may contain reasonably intact DNA. (The Denver Post)
  • Not just because of running to catch the bus. People who use public transit tend to be more active in general. (Obesity Panacea)
  • What the !?%$#**! do we know about human mutation rates, anyway? Less than you might think. (John Hawks Weblog)
  • This confirms what I already believe about both anti-vaxxers and corporate PowerPoint use. A GlaxoSmithKline presentation on the importance of vaccination leaves Jason Goldman pondering cognitive bias and the vital importance of good PowerPoint use. (The Thoughtful Animal)
  • All part of a conspiracy by socialist Radiolarians. Analysis of carbon isotopes in sediment cores suggest that a period of climatic warming in the middle Eocene was caused by increased atmospheric carbon dioxide. (Scientific American)
  • WTF is hepato-splen? That’s just one of many questions Scicurious can’t answer about a truly bizarre study investigating the effect of lunar phases on women’s menstrual cycles. (Neurotic Physiology)

Video this week, via io9: German researchers have determined that bats recognize bodies of water by echolocation because, when presented with a metal plate that reflects sound the way water does, they try to drink from it.

Carnival of Evolution No. 29

The 20th edition of the Carnival of Evolution is now online at Byte Size Biology—where the compilation of evolution-themed online writing is given a sporting spin. Check it out!

Science online, mysterious extra vertebrae edition

Wow. Lots of links this week. I’m using Google Reader again, so evidently getting better at aggregation and/or wasting valuable dissertation-completion time.

  • Shape up, Dad. Female rats are more prone to develop diabetes if their fathers were obese—through an inherited metabolic disorder. (Neurotic Physiology)
  • Also useful for studying how lizards rebel against their creators. To study how lizards communicate, build a robotic lizard. No, really. (The Thoughtful Animal)
  • Sounds like the basis for a very strange odd-couple sitcom. Can a spider and a plant be competitors? Maybe, if the plant is carnivorous. (It Takes 30)
  • A species in the genus Rosa by any other taxonomic identifier … Rod Page contemplates the importance of taxonomic names to biological research, and how to handle them in modern data structures. (iPhylo)
  • Nobody could’ve predicted. BP’s cost-cutting and rapid corporate expansion probably contributed to a corporate culture prone to accidents. (ProPublica)
  • One more way in which sloths are weird. Almost all mammals—giraffes included—have seven vertebrae in their necks. But sloths have up to 10. A new developmental study suggests how those extra vertebrae evolved. (NY Times, h/t Mike the Mad Biologist)
  • Every little bit helps. A new study suggests that, without modern conservation efforts, the ongoing extinction crisis would be even worse. (Southern Fried Science)
  • Um. Doesn’t that defeat the purpose? Placebos are used all the time in pharmaceutical research, but very few published studies actually report what the placebo was made of. (Helen Jacques)
  • The salmon of doubt. The inaugural article in the Journal of Unusual and Serendipitous Results casts doubt on interpretation of functional MRI readings—when its authors find brain activity in a dead fish. (Byte Size Biology)
  • But it looks so cool when Don Draper does it. Dave Munger ponders the ultimate effectiveness of smoking bans and warnings. (SEED Magazine)
  • “Aspergirls” is one catchy neologism. Steve Silberman continues his exploration of human experience on the Autism spectrum with comedienne Rudy Simone—and opens an ongoing conversation with her at The Well. (NeuroTribes)

More sloth weirdness on video: they can swim! But the water’s a dangerous place, as David Attenborough will tell you.

Denim and Tweed has been assimilated

Resistance was futile. I’ve had the “followers” widget from Google/Blogger for quite awhile now, and it’s clear it’s not seeing a tremendous amount of use. I infer that at least part of this is because it requires readers to use a login that they don’t have, or don’t use very frequently.

So I’m going to experiment with the current lingua franca of the social internet: Facebook, via Networked blogs, which I’ve seen used to good effect on several larger, more respectable science blogs I follow. Now, if you read Denim and Tweed, and if you like it, and if you want to like it in some sort of visible manner,* you can just click on the big blue button at the bottom of the new box on the right, as illustrated here.

Seriously, please click. My little thumbnail avatar looks so lonely right now.

Science online, electrifying history edition

  • But there’s no mention of the mouse who helped him. Dr. Skyskull unwinds the history of Benjamin Franklin’s famous kite experiment, drawing on original reports in Proceedings of the Royal Society. (Skulls in the Stars)
  • $%@!!?#! Saying an expletive aloud actually helps you tolerate pain. (Neurotic Physiology)
  • I’m guessing that animated tattoos will be first. Stretchable sheets of micro-electronic components will have all sorts of science-fictiony medical applications. (All that matters)
  • It’s an even longer way to amphioxus than we thought. MicroRNA analysis suggests that hagfish, long thought to be the most deeply-diverged relatives of vertebrates, aren’t. (Wired Science)
  • On the wrong track. Dave Munger suggests that the same cognitive bias revealed by the “trolly car” dilemma may underlie people’s willingness to believe pseudoscientific explanations for autism. (SEED Magazine)
  • Like calcium carbonate shells, scansion breaks down at low pH. The perils of ocean acidification, explained in (mostly) rhyming couplets. (Deep Sea News)
  • The king of the Red Queen is dead. Leigh Van Valen, originator of the Red Queen hypothesis, died last weekend. (dechronization)
  • There’s so many, we really ought to have some sort of systematic way to classify them. John S. Wilkins tackles species concepts. (Evolving Thoughts)

Video this week is the supplementary information for a recent study of sloth locomotion [$a] (via Wired Science)—the research found that, although they do it upside-down, sloths move a lot like other mammals.

Science online, chasing the rainbow edition

Photo by dachalan.
  • In case you missed it the first time around. BoingBoing marked National Coming Out Day this Monday with great pieces by Maggie Koerth-Baker and Steve Silberman documenting the experiences of sexual minorities in the sciences. See also the personal story of the gay son of a physics professor who called himself “a proud homophobe”, an article in Science Careers, and a forthcoming study of LGBT experiences in engineering [PDF].
  • Lucky for them, they never invented jet travel. Sea anemones—whose common ancestor with humans lived about 600 million years ago—possess some of the same physiological features that give us our circadian rythym. (Dave Munger for SEED Magazine)
  • Gesundheit! A universal flu vaccine may be possible, in the not-too-distant future. (Virology Blog)
  • Congratulations! Ed Yong wins a National Academies Communications Award for Not Exactly Rocket Science.
  • Being somewhat wrong is better than knowing nothing at all. Estimates of the rates at which species arise based on phylogenies still work pretty well if there is uncertainty or error in the phylogeny. (dechronization)
  • Oy. Nature‘s science news feature mistakenly refers to platypuses (platypi? platypodes?) as marsupials. (The Tree of Life)
  • Fossil forests! In commemoration of Wednesday’s National Fossil Day, Anne Jefferson presents a virtual field trip to the John Day Fossil Beds in eastern Oregon. (Highly Allochthonous)
  • To be fair, hoverflies are not very bright. Orchids pollinated by aphid-feeding hoverflies smell like aphids. (LabSpaces)

Why I’m out online

ResearchBlogging.orgExactly a year ago today, I came out of the online closet. Now it’s another National Coming Out Day, and it seems like as good a time as any to think out loud about why I made that decision.

Image borrowed from Wikipedia under fair use rationale.

My reasons aren’t going to surprise anyone who has even a passing familiarity with gay rights history:

  • Familiarity breeds acceptance. This is mainly a political argument. It’s widely accepted (and supported by ongoing public opinion surveying) that people who personally know GLBT folks are overwhelmingly more likely to support treating GLBT people like full citizens. The psychology isn’t hard to understand—it’s easy to hate the nebulous, faceless, unknown Gays; it’s rather harder to hate your son, or your niece, the nice neighbors who let you borrow their lawnmower, or (I hope) the guy who writes that one not-entirely-terrible science blog you check every so often.
  • Gotta give’em hope. And an example. This is more personal. I grew up without knowing any out gay people, which was, to put it mildly, not helpful. I was, to paraphrase the Onion headline, The Only Homosexual in the World; I didn’t have any of the support, or visible examples, that would’ve helped me think critically about my sexual orientation or imagine a future in which I was out, and happy about it. (Which I very much am, these days.) By being open about my orientation, maybe I can help someone else figure out his (or hers) in a way I couldn’t, and even show that, as confusing and frequently miserable as growing up gay is, it gets better.

And if there’s one impression I hope to give a confused, lonely (and presumably nerdy) gay kid reading D&T, it’s that it did get better for this formerly confused, lonely (and unquestionably nerdy) gay kid. And a large part of how it got better, for me, has to do with going into science.

Evolutionary biology has turned out to be a good field for me, in this personal respect. When I started my first genuine biology-related internship, I was surrounded for the first time by people who didn’t talk about gays in the hushed, scandalized tones I’d heard through a lot of my childhood and schooling. Biologists are as human as the next ape descendent, but they’re also a generally open-minded bunch who tend to be more interested in the quality of your work than what you do after you leave the lab. And, for what are probably obvious reasons, evolutionary biology doesn’t attract the sort of people who hold doctrinaire conservative religious positions on any subject.

Evolutionary biology is also a pretty good academic discipline for me because evolutionary biology has something to say about sexual minorities, just as it has something to say about humans in general. Humans are biological beings, and we’re part of an animal kingdom that exhibits a wide array of sexual behaviors, as elaborately documented by the evolutionary biologist Joan Roughgarden in her book Evolution’s Rainbow. Exactly how to explain this diversity, particularly in the case of humans, is still quite controversial [$a]—but it’s a question for which I have some expertise, and one I’d like to weave into the writing I do for D&T in the future.
