“Cuttlefish can remember what they ate, where, and when, and use this to guide their feeding decisions in the future,” said co-author Alexandra Schnell of the University of Cambridge, who conducted the experiments at the Marine Biological Laboratory in Woods Hole, Massachusetts. “What’s surprising is that they don’t lose this ability with age, despite showing other signs of aging like loss of muscle function and appetite.”

  • the “spiralist“, perhaps the most fascinating historical-scientific-insightful thing I’ve read this year

Pettigrew confessed himself totally spellbound by the mystery of Nature’s most ubiquitous, liquid, and quixotic form — the spiral.
Pettigrew’s newspaper model showed that the heart’s double helical structure — now known as the helical ventricular myocardial band (HVMB) — was essentially a triple-twisted Möbius strip.
In both arenas of animal physiology, Pettigrew found a spectacular resonance: movement at once precedes and follows structure, the direction of movement in living things being in every instance determined by the composition and configuration of kinetic spiral parts. This resonance seemed to reach right down to the atomic level. Unlike the closed system of the heart, the spiraling lines of atoms and molecules were arranged so that matter could be added in any amount, in unlimited directions. An open flow of energy and form was the basis for growth and progression in all creatures.

People

Doctors are baffled by the rare disease and have concluded that he is the only person in the US to have the suction capability.
Not only is he able to stick objects to his skin, but his wounds heal faster, he gets sick less and ages slower than the average person.

27 feet tall. 77 tons. Lead, steel, and glass armor almost two feet thick. A 500 horsepower supercharger engine. Able to withstand 3,000 times more radiation than a human. Mighty claws able to tear, rend, and shred steel with 85,000 pounds of force…yet nimble enough to balance an egg on a spoon.

Computing

One of the questions often asked about the IBM PC is why we chose the Ctrl-Alt-Del reset sequence. We proposed Ctrl-Alt-Del as a warm-boot sequence to provide some of the capability of a reset switch. It is difficult to activate by mistake, since the keys are widely separated. By storing a special character in a particular memory location, the warm boot would bypass the memory-test portion of the power-on self test (POST), taking less time than turning the machine off and back on.
