For many of us, listening to music is simply part of the driving routine – as ordinary as wearing a seatbelt. We build playlists for road trips, pick songs to stay awake, and even turn the volume up when traffic gets stressful.
Getting older means losing things. Some are fine, like any f**ks you have left to give or your tolerance for cheap tequila. Others, like the ability to follow a conversation in a loud room, hit harder.
But scientists now think there’s a way to fight back. And it might start at a piano bench.
Researchers publishing in PLOS Biology found that older adults who have played music for decades have brains that function more like those of someone half their age, at least when it comes to understanding speech in loud environments. In brain scans, they showed cleaner, more focused activity while listening to spoken syllables buried in background noise. Their brains weren’t scrambling. They already knew what to do.
NOTE: Some folks have mentioned my pronunciation of Gödel is wrong, I do apologize for that.
Any author mulling artificial intelligence as a story element owes it to themselves to encounter this spellbinding, one-of-a-kind book. You also deserve to sit down with it if you’re curious about any number of other SF&F-adjacent topics: mathematics, pattern recognition, the definition of consciousness, the concepts of recursion (finite and infinite)… but most of all, the way profundity can be made to look like pure play.
Functions describe the world. Join me on a tour of hyperspace, and see the many strange creatures that live there. They are just functions with lots of inputs and outputs. They are parametric surfaces that take inputs u and v, and output spatial x, y, z coordinates, and r, g, b, a color outputs. This produces a colored 3D surface. Then you can add additional inputs and visualize a single slice of each input parameter, and slide through different parameter values to see different slices of the function over time. This causes the colored surface to evolve over time. I take my time to build up the mathematical intuitions behind visualizing functions, starting with 1-in-1-out functions, and pushing it up to 7-in-7-out functions, and beyond.
Users accessing the SoundCloud audio streaming platform through a virtual private network (VPN) connection are denied access to the service and see a 403 ‘forbidden’ error.
SoundCloud is a large audio distribution platform focused on user-uploaded content, built around independent creators rather than licensed music from major labels. It has at least 140 million registered users and 40 million creators.
Due to its open, unmoderated nature, the platform has been banned in China since 2014, in Russia since 2022, and is restricted in Venezuela, Kazakhstan, and other countries. Because of this, users in these regions rely on a VPN or proxy solution to bypass the blocks.
In this video, Whitney, a registered dental hygienist, breaks down the viral headlines about a “tooth regrowth shot” being tested in Japan. She explains the real science behind the drug — how it targets the USAG-1 protein to potentially reactivate dormant tooth buds — and clears up common misconceptions about tooth regeneration research. From animal trials to current human safety studies, Whitney dives into what’s fact, what’s hype, and what this breakthrough could mean for the future of dentistry.
Neal Agarwal published another gift to the internet with Size of Life. It shows the scale of living things, starting with DNA, to hemoglobin, and keeps going up.
The scientific illustrations are hand-drawn (without AI) by Julius Csotonyi. Sound & FX by Aleix Ramon and cello music by Iratxe Ibaibarriaga calm the mind and encourage a slow observation of things, but also grow in complexity and weight with the scale. It kind of feels like a meditation exercise.
