New sphere-packing record stems from an unexpected source

news.ycombinator.com Joseph Howlett 2025-08-11 03:19:13

The advantage of Rogers’ method was that you didn’t have to start with a particularly efficient lattice to get an efficient sphere packing. You just had to choose the right ellipsoid. But this introduced a new complication. Unlike a sphere, which is completely defined by a single number — its radius — an ellipsoid is defined by several axes of different lengths. The higher the dimension, the greater the number of directions you can stretch your ellipsoid in, and the more options you have for wha

Joe Rogan loves talking about artificial intelligence. Whether it’s with Elon Musk, academics, or UFC fighters, the podcast king often returns to the same question: What happens to us when machines start thinking for themselves?

New Research Debunks Myth That Brain Cells Stop Growing After Childhood

gizmodo.com Ed Cara 2025-08-15 11:00:50

You’ve probably heard the old canard that new brain cells simply stop forming as we become adults. But research out today is the latest to show that this isn’t really true. Scientists in Sweden led the study, published Thursday in Science. They found abundant signs of neural stem cells growing in the hippocampus of adult brains. The findings reveal more about the human brain as we get older, the researchers say, and also hint at potential new ways to treat neurological disorders. “We’ve found

What links a Möbius strip, brain folds and termite mounds? The answer is Harvard University’s L.

Mahadevan, or Maha to his friends and colleagues, has long been fascinated by questions one wouldn’t normally ask — from the equilibrium shape of inert objects like a Möbius strip, to the complex factors that drive biological systems like morphogenesis or social insect colo

Gareth Edwards Is Glad You Liked ‘Rogue One,’ Just Don’t Ask Him to Make Another ‘Star Wars’

Gareth Edwards, who directed Godzilla (2014), The Creator, and the brand-new Jurassic World Rebirth, is always going to be asked about his time in the galaxy far, far away. That’s just the nature of Star Wars and, more specifically, Star Wars fans, most of whom look very fondly upon 2016’s Rogue One: A Star Wars Story—especially in the wake of Andor‘s two-season run on Disney+.

For the first time in bug bounty history, an autonomous penetration tester has reached the top spot on the US leaderboard.

Factories have used fossil fuels to process iron ore for three centuries, and the climate has paid a heavy price: According to the International Energy Agency, the steel industry today accounts for 8% of carbon dioxide emissions. But it turns out there is a less carbon-intensive alternative: using hydrogen. Unlike coal or natural gas, which release carbon dioxide as a by-product, this process releases water. And if the hydrogen itself is “green,” the climate impact of the entire process will
