Imagine that a grid of hexagons, honeycomb-like, stretches before you. Some hexagons are empty; others are filled by a 6-foot tall column of solid concrete. The result is a maze of sorts. For over half a century, mathematicians have posed questions about such randomly generated mazes. How big is the largest web of cleared paths?… Continue reading Maze Proof Establishes a ‘Backbone’ for Statistical Mechanics
CLIMATEWIRE | Global electricity demand will step up its rate of growth over the next three years — but the additional power use will be covered by low-emissions sources, according to a report released Wednesday by the International Energy Agency. The IEA’s Electricity 2024 report forecasts that renewable energy is set to overtake the world’s use of coal… Continue reading Renewable Power Set to Surpass Coal Globally by 2025

The team built their hash table in two parts. They had a primary data structure, in which the items are stored without any wasted bits at all, and a secondary data structure, which helps a query request find the item it’s looking for. While the group did not invent the notion of a secondary data… Continue reading Scientists Find Optimal Balance of Data Storage and Time

And on the flip side, which black holes stand out to you as particularly extreme or particularly weird? I like to study the normal guys, and then I like to crank things up and see where things break. What’s also really fun are the oddball systems that just keep you up at night wondering: How… Continue reading To See Black Holes in Detail, She Uses ‘Echoes’ Like a Bat
Two years ago, in a project called the Beyond the Imitation Game benchmark, or BIG-bench, 450 researchers compiled a list of 204 tasks designed to test the capabilities of large language models, which power chatbots like ChatGPT. On most tasks, performance improved predictably and smoothly as the models scaled up — the larger the model,… Continue reading How Quickly Do Large Language Models Learn Unexpected Skills?
When most of us go to the beach, we like to play in the sand, frolic in the surf and people watch. I like all those things, too. But I am also a massive science nerd, and that means that despite the distractions, I cannot tear my attention away from the horizon. Oh, that line… Continue reading How Far Away Is the Horizon?
