Solving a machine-learning mystery

Researchers have explained how large language models like GPT-3 are able to learn new tasks without updating their parameters, despite not being trained to perform those tasks. They found that these large language models write smaller linear models ins…

Why icicles are rippled

Winter is coming to an end; the last nights of below zero temperatures are here. In the morning, one still spots the occasional icicle on a gutter or car bumper. When you look at these icicles carefully, you may notice that they show a characteristic p…

Researchers focus AI on finding exoplanets

New research reveals that artificial intelligence can be used to find planets outside of our solar system. The recent study demonstrated that machine learning can be used to find exoplanets, information that could reshape how scientists detect and iden…

New models explain canyons on Pluto moon

In 2015, when NASA’s New Horizons spacecraft encountered the Pluto-Charon system, scientists discovered interesting, geologically active objects instead of the inert icy orbs previously envisioned. Scientists have revisited the data to explore the sour…

Antarctica’s ocean brightens clouds

The teeming life in the Southern Ocean, which encircles Antarctica, contributes to brightening the clouds that form there, according to a new study. The clouds are bright because of their high density of water droplets, due in turn to a chain of atmosp…
