Geometers Engineer New Tools to Wrangle Spacecraft Orbits

You can create a graph with the angle as the x-axis and the speed as the y-axis. But since traveling 360 degrees brings you back to the start, you can sew together the vertical lines where x is zero degrees and where x is 360 degrees. This makes a cylinder. The cylinder doesn’t directly reflect… Continue reading Geometers Engineer New Tools to Wrangle Spacecraft Orbits

Pleasure or Pain? He Maps the Neural Circuits That Decide.

Does finding this skin-to-brain pathway have any medical implications? Yes, the skin is a good therapeutic target. It’s accessible and presents a direct highway to the part of the brain that makes us feel good. What if we could turn on these neurons with a skin cream to improve mental health — say, to offset… Continue reading Pleasure or Pain? He Maps the Neural Circuits That Decide.

Why Fatal Police Shootings Aren’t Declining: Some Uncomfortable Facts

When Dexter Reed died in a shootout with Chicago police on March 21, the incident was quickly grafted onto a narrative that began in 2014 after a policeman killed Michael Brown in Ferguson, Mo. – namely, that the U.S. faces an epidemic of violence by unbridled cops who do not believe black lives matter. “Killing… Continue reading Why Fatal Police Shootings Aren’t Declining: Some Uncomfortable Facts

Hopes of Big Bang Discoveries Ride on a Future Spacecraft

The theory has its flaws. For instance, the mass of the Higgs boson — the component of the Standard Model that determines the masses of other particles — is frustratingly “unnatural.” It appears arbitrary, and puzzlingly small compared to the far greater energy scales of the universe. Moreover, the Standard Model offers no explanation for… Continue reading Hopes of Big Bang Discoveries Ride on a Future Spacecraft

NASA’s Voyager 1 Is Bound for the Great Beyond

In the fall of last year, one of NASA’s most venerable spacecraft started beaming home nonsense. Its usual string of 1’s and 0’s—binary code that collectively told of its journey into the unknown—became suddenly unintelligible. Some 15 billion miles from Earth, beyond the protective bubble blown by the sun and in interstellar space, Voyager 1… Continue reading NASA’s Voyager 1 Is Bound for the Great Beyond

Math Can’t Solve Gerrymandering

Math Can’t Solve Gerrymandering Researchers use powerful geometrical methods to try fixing unfair districts. That alone isn’t enough; we need to fight the values behind gerrymandering By Matthew R. Francis Voters cast their ballots at a polling station inside the Adamsville Baptist Church in Goldsboro, North Carolina, US, on Tuesday, March 5, 2024. This year’s… Continue reading Math Can’t Solve Gerrymandering

Overexposure Distorted the Science of Mirror Neurons

In the summer of 1991, the neuroscientist Vittorio Gallese was studying how movement is represented in the brain when he noticed something odd. He and his research adviser, Giacomo Rizzolatti, at the University of Parma were tracking which neurons became active when monkeys interacted with certain objects. As the scientists had observed before, the same… Continue reading Overexposure Distorted the Science of Mirror Neurons
