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

Math Proof Draws New Boundaries Around Black Hole Formation
The modern notion of a black hole has been with us since February 1916, three months after Albert Einstein unveiled his theory of gravity. That’s when the physicist Karl Schwarzschild, in the midst of fighting in the German army during World War I, published a paper with astonishing implications: If enough mass is confined within… Continue reading Math Proof Draws New Boundaries Around Black Hole Formation
Racism in Health: The Roots of the U.S. Black Maternal Mortality Crisis
[CLIP] Window rolling down Tulika Bose [tape]: Hey, what’s that? Protestor: It’s a brochure about all the help that’s available for pregnant women. Bose: I’m pulling up to one of the last clinics in Georgia where you can still get a medical abortion. Protestor: [tape] It’s a brochure. Bose: [tape] What’s it a brochure about? … Continue reading Racism in Health: The Roots of the U.S. Black Maternal Mortality Crisis
Complexity Theory’s 50-Year Journey to the Limits of Knowledge
Impediments remain to proving NP-completeness for the full version of MCSP. But none are the sort of barriers that suggest an entirely new toolkit is needed — it may just be a matter of finding the right way to combine known techniques. A proof would finally settle the status of one of the few problems… Continue reading Complexity Theory’s 50-Year Journey to the Limits of Knowledge
Quaking Giants Might Solve the Mysteries of Stellar Magnetism
Our planet is doomed. In a few billion years, the sun will exhaust its hydrogen fuel and swell into a red giant — a star so big it will scorch, blacken and swallow up the inner planets. While red giants are bad news for planets, they’re good news for astrophysicists. Their hearts hold the keys to understanding… Continue reading Quaking Giants Might Solve the Mysteries of Stellar Magnetism
