Then they led him out again, trying to get him near a mockup of a Mercury capsule, where the television networks had set up cameras and tremendous lights. The reporters and photographers surged forward again, yammering, yelling, exploding more camera lights, shoving, groaning, cursing—the usual yahoo sprawl, in short—and the animal came unglued again, ready […]


Sulfolobus solfataricus P2 DNA polymerase IV (Dpo4) is a DinB homolog that belongs to the recently described Y-family of DNA polymerases, which are best characterized by their low-fidelity synthesis on undamaged DNA templates and propensity to traverse normally replication-blocking lesions.

For the first time, we may have just detected the a large object that has entered our solar system from interplanetary space: C/2017 U1 PanSTARRS. It’s a shame we don’t have a spacecraft ready to go get a closer look, or maybe even get a sample.

The chapter about them is perhaps the most memorable part of Douglas Adams’ excellent non-fiction […]


Columbus could not have foreseen the results of his search for piperine, Magellan was unaware of the long-term effects of his quest for isoeugenol, and Schönbein would surely have been astonished that the nitrocellulose he made from his wife’s apron was the start of great industries as diverse as explosives and textiles. Perkin could not […]


In many ways, the treatment of ethanol in societies like Canada is exceptional. It’s the only powerfully psychoactive drug top-end hotels and restaurants will provide you in unlimited quantities as long as you can pay. It’s the only drug that large groups of strangers routinely use to the point of inebriation together, in contexts ranging […]
