When it comes to bodies, at least down to the level where quantum uncertainty becomes important, there seems to be no reason why sufficiently powerful computer hardware could not produce an excellent simulation. In the long term, that could allow things like the development and practicing of surgical techniques on simulated bodies; improved testing for safety in diverse applications; and research into animal physiology.
Perhaps brains are different; there may be something about consciousness that keeps it from being modelled by any conventional computer, regardless of its memory and processing capabilities. Still, it’s possible that consciousness can also be simulated, or re-created in a digital form, perhaps with the aid of quantum computers.
Richard Dawkins’ Unweaving the Rainbow includes a great discussion of the scientific uses of the Fourier transform. Most amusingly: “The side-to-side waving of the urine trail on the road was presumably produced by the long [elephant] penis acting as a pendulum (it would be a sine wave if the penis were a perfect, Newtonian pendulum, which it is not) interacting with the more complicated periodicity of the lumbering four-legged gait of the whole animal.” (p. 73)
This video provides an accessible visual explanation of how this mathematical tool breaks down a complicated curve into its constituent sine waves, and some of the useful applications for that transformation:
Not only does continued bitumen sands investment perpetuate an industry which undermines Canada’s claim to be serious about Indigenous reconciliation, but giving the industry specially lax environmental treatment would force other sectors to pick up the slack, if that is even possible given the industry’s relentlessly growing pollution.
An article by University of Toronto professor Danny Harvey and Lika Miao now argues that only an oil sands phaseout would allow Canada to meet its (insufficiently ambitious) 2030 emission reduction targets. They see a complete bitumen sands phase out by 2030 as necessary to meet the targets, alongside major action in sectors like energy generation, and emphasize how meeting the more ambitious temperature targets of the Paris Agreement would require much more aggressive action.
All this highlights the chasm between Canadian politics and what would be necessary to curb climate change. Prime Minister Trudeau either doesn’t understand the relationship between fossil fuel use and climatic stability or is choosing to mislead Canadians for political reasons, continuing to assert that Canada’s fossil fuel reserves are usable. That kind of timidity or misdirection serves us all badly, leaving the bulk of Canadians misled into believing that the industry can somehow be compatible with a stable climate.
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, cursingâ€”the usual yahoo sprawl, in shortâ€”and the animal came unglued again, ready to twist the noodle off anybody he could get his hands on. This was interpreted by the Gent [the news media] as a manifestation of Ham‘s natural fear upon laying eyes once again on the capsule, which looked precisely like the one that had propelled him into space and subjected him to such severe physical stresses.
The stresses the ape was reacting to were probably of quite another sort. Here he was, back in the compound where they had zapped him through his drills for a solid month. Just two years ago he had been captured in the jungles of Africa, separated from his mother, shipped in a cage to a goddamned desert in New Mexico, kept prisoner, prodded and shocked by a bunch of humans in white smocks, and here he was, back in a compound where they had been zapping him through their fucking drills for a solid month, and suddenly there was a whole new mob of humans on hand! Even worse than the white smocks! Louder! Crazier! Totally out of their gourds! Yammering, roaring, brawling, exploding lights beside their bug-eyed skulls! Suppose they threw him to these assholes! Fuck thisâ€”
At some point in the madhouse scene out back of Hanger S, a photograph was taken in which Ham was either grinning or had on a grimace that looked like a grin in the picture. Naturally, this was the picture that went out over the wire services and was printed in newspapers throughout America. Such was the response of the happy chimpanzee to being the first ape in outer space … A fat happy grin… Such was the perfection with which the Proper Gent observed the proprieties.

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.
People with good security practices like defence in depth and compartmentalization of sensitive information might not be too threatened by this. Those relying exclusively on the integrity of WPA2 may be in big trouble.

New Zealand’s kakapo parrot is equally rare and bizarre: critically endangered, with 154 survivors living on three protected predator-free islands, the birds can’t survive the presence of rats, cats, and other potentially-carniverous mammals, can’t fly, and reproduce slowly and strangely.
The chapter about them is perhaps the most memorable part of Douglas Adams’ excellent non-fiction book Last Chance to See.
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 SchÃ¶nbein 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 have anticipated that his small experiment would eventually lead not only to a huge synthetic dye trade but also to the development of antibiotics and pharmaceuticals. Marker, Nobel, Chardonnet, Carothers, Lister, Baekeland, Goodyear, Hofmann, Leblanc, the Solvay brothers, Harrison, Midgley, and all the others whose stories we have told had little idea of the historical importance of their discoveries. So we are perhaps in good company if we hesitate to try to predict whether today there already exists an unsuspected molecule that will eventually have such a profound and unanticipated effect on life as we know it that our descendants will say, “This changed the world.”
