Algorithms have become ubiquitous. They optimize our commutes, process payments and coordinate the flow of internet traffic. It seems that for every problem that can be articulated in precise mathematical terms, there’s an algorithm that can solve it, at least in principle. But that’s not the case — some seemingly simple problems can never be… Continue reading Alan Turing and the Power of Negative Thinking

Magnetism May Have Given Life Its Molecular Asymmetry
Some event or series of events early in the history of life must have “broken the mirror,” as biochemists put it, throwing life into molecular asymmetry. Scientists have debated why life became homochiral, and whether it needed to happen or if it was purely a fluke. Were chiral preferences impressed on early life by biased… Continue reading Magnetism May Have Given Life Its Molecular Asymmetry
The AI Tools Making Images Look Better
It’s one of the biggest cliches in crime and science fiction: An investigator pulls up a blurry photo on a computer screen and asks for it to be enhanced, and boom, the image comes into focus, revealing some essential clue. It’s a wonderful storytelling convenience, but it’s been a frustrating fiction for decades — blow… Continue reading The AI Tools Making Images Look Better
What Caused Maui’s Devastating Wildfires?
Editor’s Note (8/21/23): This article was updated after posting to include new details of the situation on the ground, including the death toll from the fires. At least 114 people have been confirmed to be killed by wildfires that raged uncontrolled on the famously beautiful Hawaiian island last week. People were left with little time to escape from… Continue reading What Caused Maui’s Devastating Wildfires?
What a Contest of Consciousness Theories Really Proved
Dehaene favored the second experiment, which also involved the comprehensive decoding of brain patterns. Test subjects would be randomly exposed to faces and objects flashed on a screen while they played a distracting Tetris-like video game. Shortly after an image was shown, the game would stop and the subject would be asked whether they saw… Continue reading What a Contest of Consciousness Theories Really Proved
New Codes Could Make Quantum Computing 10 Times More Efficient
Through these checks — and more subtle tweaks of the iffy qubits — you can also hide a reliable qubit throughout the square block’s data-carrying qubits, not exactly here or there but sort of everywhere. As long as the iffy qubits keep the Minesweeper operations humming along smoothly, the hidden qubit stays safe and can… Continue reading New Codes Could Make Quantum Computing 10 Times More Efficient
The Hidden Brain Connections Between Our Hands and Tongues
One day, while threading a needle to sew a button, I noticed that my tongue was sticking out. The same thing happened later, as I carefully cut out a photograph. Then another day, as I perched precariously on a ladder painting the window frame of my house, there it was again! What’s going on here?… Continue reading The Hidden Brain Connections Between Our Hands and Tongues
Strange Ecosystem Found Thriving below Seafloor Hydrothermal Vents
There may be no ecosystem on Earth that seems less hospitable than hydrothermal vents. In the perpetual darkness, cold and relentless pressures of the deep sea, these volcanic seeps spew piping hot water so loaded with particles and metals that it looks like black smoke billowing from a chimney. But even these hellish habitats are… Continue reading Strange Ecosystem Found Thriving below Seafloor Hydrothermal Vents
In a Monster Star’s Light, a Hint of Darkness
His team’s analysis, published in June in Monthly Notices of the Royal Astronomical Society, did not find evidence for wavelike dark matter effects in high-resolution images of arcs of light from one gravitational lens, suggesting that the dark particle must be heavier than the smallest fuzzy candidates. But an April study in Nature Astronomy, led… Continue reading In a Monster Star’s Light, a Hint of Darkness
