Dopamine is one of the most extensively studied chemical messengers in the human brain, and yet scientists are still figuring out how it works to accomplish so much. For years, the classic view has been that, when released, dopamine slowly diffuses through the brain like a chemical megaphone, broadcasting information far and wide to numerous target cells. Recently, however, that …

Image: BitSummit BitSummit has once again come and gone, and unlike last year where it was a bit difficult to find indie developers committing to a Nintendo Switch release well before the Switch 2 was announced, we found a renewed enthusiasm for Nintendo as we pursued the two floors BitSummit took over in Kyoto’s Miyako Messe convention center. BitSummit is …

The discovery of ancient human cousins has long stirred wonder and debate. Early Neanderthal remains offered a glimpse into our distant past, prompting questions about how they lived and whether they mingled—or clashed—with early humans. The plot thickened with the later discovery of Denisovans, another mysterious branch of the human family tree. Each new finding deepened the mystery of who …

Even after pouring $2 billion into its much-maligned Starliner spacecraft, NASA and Boeing remain committed to getting back off the ground. As Ars Technica reports, the head of NASA’s commercial crew program, Steve Stich, revealed last week that Boeing and its propulsion supplier, Aerojet Rocketdyne, are making considerable changes to the astronaut shuttle following a disastrous first crewed mission to …

KEY POINTS Jupiter, Saturn, and Neptune each emit more energy than they receive from the Sun, meaning they have comparatively warm interiors. NASA’s Uranus flyby with Voyager 2 in 1986 found the planet colder than expected, which challenged ideas of how planets formed and evolved. However, with advanced computer modeling and a new look at old data, scientists think the …

Fossils are invaluable archives of the past. They preserve details about living things from a few thousand to hundreds of millions of years ago. Studying fossils can help us understand the evolution of species over time, and glimpse snapshots of past environments and climates. Fossils can also reveal the diets or migration patterns of long-gone species – including our own …

As large language models (LLMs) grow more capable, the challenge of ensuring their alignment with human values becomes more urgent. One of the latest proposals from a broad coalition of AI safety researchers, including experts from OpenAI, DeepMind, Anthropic, and academic institutions, offers a curious but compelling idea: listen to what the AI is saying to itself. This approach, known …

When Voyager 2 flew past Uranus in 1986, the spacecraft detected a surprisingly low level of internal heat from the planet. Since then, scientists believed Uranus to be the odd one out in our solar system’s family of giant planets—the others being Jupiter, Saturn, and Neptune—who all tend to emit more heat than they absorb from sunlight. Now, a new …
