Life versus the molecular storm

lifes-ratchetRichard Feynman put it best: “Things on a very small scale behave like nothing that you have any direct experience about. They do not behave like waves, they do not behave like particles, they do not behave like clouds, or billiard balls, or weights on springs, or like anything that you have ever seen… Because atomic behavior is so unlike ordinary experience, it is very difficult to get used to, and it appears peculiar and mysterious to everyone.”

The same could be said about things on a very large scale, such as planets and galaxies. It could also be said about extremes of time and temperature – we have no direct experience with microseconds and millions of years, or with what happens at thousands of degrees or near absolute zero. Scientific concepts that deal with such extremes defy our meso-scale common sense.

We respond to these assaults on our intuition sometimes with gee-whiz fascination, and at other times, when cherished beliefs are on the line, with resistance. Can our mundane actions really change the climate of something so large as the earth? How could we possibly have descended from small, furry dinosaur prey? And if a tornado whipping through a junkyard can’t spontaneously create a Boeing 747, can it really be true that complex, living, self-directing beings are formed out of molecules that merely follow the laws of physics and chemistry, without the guiding influence of vital spirits?

Dirty Minds: Your love life is supposed to be complicated

Kayt Sukel’s Dirty Minds is a book about neuroscience that has questions, not answers. That alone should be enough reason for you to pick it up. Sukel’s agenda is not to tell her reader how the human mind works. It is to convince her reader that our minds are complicated messes – they are dirty, in the cleanest sense of the term1. Our mind is the result of a rat’s nest of neurons bathed in a complex soup of hormones interacting with our environment. The point is not that our dirty minds have been solved, but that they are so damned interesting.

If you need another reason, a lot of the book is about sex2. Really, it is about research into the neurological basis of love. It covers relationships, parenting, even a wee bit of religion, and sex; but, when you say “and sex”, you might as well say “it’s about sex”.  Continue reading “Dirty Minds: Your love life is supposed to be complicated”

Meet the Pselaphinae

A Snapshot of Pselaphine Beetle Diversity: plates from Raffray’s Étude sur les Psélaphides (1890)

Guest post by Joseph Parker, Coleopterist, Columbia University.

If you’ve ever been fortunate enough to walk through a rainforest, you’ll probably have noticed huge numbers of ants patrolling the ground at your feet. Ants dominate forest environments, dismembering other arthropods, harvesting honeydew from plant sucking bugs, and waging war on neighbouring colonies.

But amongst the ants exists another, far more poorly known group of creatures… a group of beetles called Pselaphinae (SEH-LA-FIN-EE). In terms of species richness they rival—and may even surpass—ants. These beetles are remarkable, being one of the most morphologically diverse groups of organisms out there, with a seemingly endless range of bizarre body forms.

ENCODE, Astronomy, & the Future of Genomics

The ENCODE media fail was epic enough that it totally dominated the discussion when the results were released to the public. Now our collective fury has abated1, I’d like to talk about, not what ENCODE did, but what it might mean for how we conduct genomic research in the future.

ENCODE produced an unprecedented amount of data with unprecedented levels of reproducibility between labs. This data will be useful to researchers around the world for year to come. To do so, however, it commanded tremendous resources and marginalized the concerns of independent researchers. Can we harness the data collection power of these collective projects without destroying the creativity and risk-taking of individual scientists in the crucible of collaborative compromise? Continue reading “ENCODE, Astronomy, & the Future of Genomics”

Meet the Sea Spider

Sea spiders are a class of marine arthropods called Pycnogonida that are found nearly everywhere in oceans from deep to shallow ranges. They are not arachnids, but considered chelicerates even though this fact may be debated. They feed on ocean invertebrates using a proboscis and suction feeding.

Sea spiders use external fertilization and interestingly the male provides care to the young.
