A Theory of Humor | Why something is funny, why it sometimes is not, and when it crosses a line.

Theory of Humor. A scientific paper, written by Tom Veatch, describes his Theory of Humor. When is something funny? When is it not funny? When does it cross the line? Why are puns generally shitty? And the mysterious and magical powers elephant jokes have on children, revealed! A great data set to use for practice in applying the theories presented in the paper can be found here.

Sexy-smelling deceptive robot cockroaches!

Remember that X-files episode? The one with the robot cockroaches from outer space? Well, scientists in Belgium have created robots that act like cockroaches, and are accepted by the real cockroaches because they smell sexy to them. Better yet, the scientists were able to use the robots to change how the cockroaches behaved. [more inside]

A slice of a lost world

The forest preserve of Białowieza is considered to be the last primeval forest in lowland Europe. Because of its unique position on the border of the temperate and boreal climate zones, it contains a unique mixture of trees, such as Norway Spruce and oaks. It also contains an interesting mix of fauna, including the European Bison, beaver, wolves, and the Nazi re-creation of an extinct species. [more inside]

Hot space bot uses stirling engine

NASA proposes using a Stirling cooler (essentially a Stirling engine in reverse) to keep a probe cool on the surface of Venus, which has had a tendency to melt or smash previous probes. The cooler would maintain a 25cm sphere within the probe at 200°C -- 100°C above the boiling point of water but sufficiently cool for a high-temperature microcontroller to operate. The waste heat radiators on the exterior of the sphere would reach the temperature of 500°C, 40°C above the the normal Venusian surface temperature.

Proust, Cezanne, Sacks, and Umami - Lehrer's World

Jonah Lehrer is becoming one of the most interesting science writers around. The 26-year-old Rhodes scholar and former Le Bernardin cook just published his first book, Proust Was a Neuroscientist [first chapter excerpt - NYT], an investigation of the ways poets, novelists, and artists accurately modeled the brain and memory before science did. This week he hilariously reenacted Escoffier's distillation of umami-rich veal stock [hit the audio link] with NPR's Robert Krulwich of Radio Lab. He also just published a very insightful profile of Oliver Sacks in SEED (addressing the pioneering neurologist's own recent struggles with an eye ailment) and writes a wide-ranging science blog. A new writer to watch.

An 18th Century Debate About Intelligent Design

Sex Ratio Theory, Ancient and Modern - An 18th Century Debate about Intelligent Design and the Development of Models in Evolutionary Biology [pdf file]. The design argument for the existence of God took a probabilistic turn in the 17th and 18th centuries. Earlier versions, such as Thomas Aquinas’ 5th way, usually embraced the premise that goal-directed systems (things that “act for an end” or have a function) must have been created by an intelligent designer. This idea – which we might express by the slogan “no design without a designer” – survived into the 17th and 18th centuries, and it is with us still in the writings of many creationists. The new version of the argument, inspired by the emerging mathematical theory of probability, removed the premise of necessity. It begins with the thought that goal-directed systems might have arisen by intelligent design or by chance; the problem is to discern which hypothesis is more plausible. From Professor Elliott Sober.

Those mud pies were actually good for you.

Have You Eaten Your Dirt Today, Honey? A New Approach To The Hygiene Hypothesis. The hypothesis argues: The reason why there is so much asthma, eczema, allergies and maybe even childhood diabetes in the modern world is because we — well infants really — live in too clean a universe. What our baby immune systems need is a kickstart by exposure to viruses, bacteria, worms, pollutants and so on. If you don’t get an infant hit from these icons of uncleanliness, the immune system goes haywire and your body over-reacts to all sorts of invasive things that normally could be ignored. Via.

The Anatomy Of Taste

Yummy Science. Researchers unravel the complex combination of physical and emotional reactions that influence our perceptions of what tastes good. Once upon a time, flavor research was a matter of asking housewives to munch a few potato chips... Now it's about providing an exceptional flavor "experience." And as scientists learn to exploit the ways we perceive flavor, food manufacturers will be able to refine their products to appeal to us as individuals. Welcome to the world of personally tailored mass-produced food.

William Hamilton and the Flaming Fields of Vesuvius

British diplomat William Hamilton (whose 2nd wife Emma is perhaps best known for having a scandalous public affair with Horatio Nelson) loved volcanoes. His 1776 book Campi Flegrei: Observations on the volcanoes of the two Sicilies* used stunning hand-coloured illustrations by Peter Fabris to demonstrate to the scientific world that volcanic processes can be beautifully creative as well as horribly destructive.

Elementary, My Dear Watson

Theodore Gray's interactive periodic table isn't the only periodic table online -- another one was posted to MeFi last month -- but I think it's the most gorgeous, informative, and ambitious periodic table I've ever seen, featuring actual samples of most of the elements and their practical uses, a fascinating display of uranium isotopes, and explosive "sodium party" videos and more from Gray's many years of obsession with the elements.

Nicod Lectures

Since 1993, the Institut Jean Nicod has awarded the annual Jean Nicod Prize to a leading philosopher or cognitive scientist for his or her work in the interdisciplinary study of the mind. The recipient is expected to deliver a series of lectures. The lecture series of this past year's winner, philosopher Stephen Stich, is entitled "Moral Theory Meets Cognitive Science: How Cognitive Science Can Transform Traditional Debates", and is now available online in video form. Also available is the lecture series of the previous year's winner, evolutionary anthropologist Michael Tomasello: "Origins of Human Communication". [more inside]

Dr. Aragon: [chuckling] Oh, yes. Those are the charmed substances that some years ago were thought to contain life-preserving properties.
Dr. Melik: You mean there was no deep fat? No steak or cream pies or... hot fudge?
Dr. Aragon: Those were thought to be unhealthy... precisely the opposite of what we now know to be true.
Dr. Melik: Incredible.

People who play gnomes are more likely to be annoying in real life.

Nick Yee's Daedalus Project (touched on previously) is dedicated to the study of human behaviour in MMOs. His recent dissertation names "The Proteus Effect": a correlation between MMO characters' appearances, and their players' behaviors. "In the final study (pdf), I showed that the Proteus Effect persists outside of the virtual environment. Placing someone in a taller avatar changes how they consequently negotiate in a face-to-face setting." His archives cover a lot of ground, and current MMO players can help by taking the survey. For a little lighter reading, refer to his critique of Internet Addiction Disorder, a "condition" that started as a joke, but almost made it into the DSM-V.

Video Ergo Sum

Virtual Out-of-Body Experience. Using two procedures to deliberately scramble a person's visual and tactile senses, neuroscientists are able to induce "out-of-body" experiences in people. The effect is the same as the 'rubber hand illusion', but extends the effect to the whole body instead of just one limb (you can try the hand illusion for yourself).
