On October 16, 1846, at Massachusetts General Hospital, Morton administered his gas through an inhaler in the mouth of a young man undergoing the excision of a tumor in his jaw. The patient only muttered to himself in a semi-conscious state during the procedure. The following day, the gas left a woman, undergoing surgery to cut a large tumor from her upper arm, completely silent and motionless. When she woke, she said she had experienced nothing at all.Four weeks later, on November 18th, Bigelow published his report on the discovery of “insensibility produced by inhalation” in the Boston Medical and Surgical Journal. Morton would not divulge the composition of the gas, which he called Letheon, because he had applied for a patent. But Bigelow reported that he smelled ether in it (ether was used as an ingredient in certain medical preparations), and that seems to have been enough. The idea spread like a contagion, travelling through letters, meetings, and periodicals. By mid-December, surgeons were administering ether to patients in Paris and London. By February, anesthesia had been used in almost all the capitals of Europe, and by June in most regions of the world.

RNAs Galore | HHMI.org

Every human body contains several trillion cells, yet each cell contains an identical DNA sequence. A good way to distinguish one cell from another is by looking at the RNAs they express – something biologists do all the time. The problem is there are thousands of different RNA species forming a cell’s transcriptome. Even with the most advanced imaging methods in biology, scientists can look at only a couple of dozen at a time. And when they focus on just a few RNA species, they’re missing out on a wealth of information.

The origins of chroot()

The chroot() system call is one of those that I think of as being really old. Up until a while back, if you’d pressed me I’d have guessed that it originated in V7. Then I dug into it and in that tweet claimed it was from 4.2 BSD. This is what you’d kind of expect and what it sort of looks like, but it turns out to be wrong and the history of chroot() seems to be much more interesting than I expected.

Grand illusions | The Economist


YOUR correspondent stands, in a pleasingly impossible way, in orbit. The Earth is spread out beneath. A turn of the head reveals the blackness of deep space behind and above. In front is a table full of toys and brightly coloured building blocks, all of which are resolutely refusing to float away—for, despite his being in orbit, gravity’s pull does not seem to have vanished. A step towards the table brings that piece of furniture closer. A disembodied head appears, and pair of hands offer a toy ray-gun. “Go on, shoot me with it,” says the head, encouragingly. Squeezing the trigger produces a flash of light, and the head is suddenly a fraction of its former size, speaking in a comic Mickey-Mouse voice (despite the lack of air in low-Earth orbit) as the planet rotates majestically below.
