Monday night

December 21, 2020

QT:{{”
For the past year, Jupiter and Saturn have been dancing ever closer in the night sky. On the evening of Dec. 21, the very nadir of winter, they will be so close — one-tenth of one angular degree — that if your eyes are as bad as mine, they will appear as one blurry, bright planet. With a little optical aid you should be able to discern them as separate orbs, almost kissing, although Jupiter will be 450 million miles in front of the ringed Saturn.

Go out and look southwest in the hour after sunset. According to astronomers, the two planets have not appeared this close to each other in the sky since 1623 — but the sun’s glare then would have rendered them invisible. To find a conjunction that humans could see, you must skip all the way back to 1226, or ahead to March 15, 2080. You might wonder who will be around to witness that event

A rare conjunction of planets serves as a reminder that there is more to the universe than just ourselves.

Sequence Variants in TAAR5 & Other Loci Affect Human Odor Perception & Naming https://www.cell.com/current-biology/fulltext/S0960-9822(20)31343-9 A variant in TAAR5 affects the perception of fish odor. Interesting to consider in relation to pseudogenization of the olfactory receptors

While about half of human odorant receptors are thought to be pseudogenes with loss-of-function, the Decode Genetics folks show that some sequence variants in odorant receptor genes are not
loss-of-function.

Much of this @jmseabrook article about facial recognition will soon be applicable to genomic privacy & individuals’ attempts to protect themselves in this sphere as well…

Adversarial examples demonstrate that deep-learning-based C.V. systems are only as good as their training data, and, because the data sets don’t contain all possible images, we can’t really trust them. In spite of the gains in accuracy and performance since the switch to deep learning, we still don’t understand or control how C.V. systems make decisions. “You train a neural network on inputs that represent the world a certain way,” Goldstein said. “And maybe something comes along that’s different—a lighting condition the system didn’t expect, or clothing it didn’t expect. It’s important that these systems are robust and don’t fail catastrophically when they stumble on something they aren’t trained on.”

The early work on adversarial attacks was done in the digital realm, using two-dimensional computer-generated images in a simulation. Making a three-dimensional adversarial object that could work in the real world is a lot harder, because shadows and partial views defeat the attack by introducing nuisance variables into the input image. A Belgian team of researchers printed adversarial images on
two-dimensional boards, which made them invisible to yolo when they held the boards in front of them. Scientists at Northeastern University and at the M.I.T.-I.B.M. Watson A.I. Lab created an adversarial design that they printed on a T-shirt. Goldstein and his students came up with a whole line of clothes—hoodies, sweatshirts, T-shirts.
