Proof of concept uses passive components to redirect heat across a chip, allowing temperature patterns to be used for data processing.

Comet Wierzchoś, also known as C/2024 E1, is rapidly brightening as it approaches its closest point to Earth next week. But experts predict it will eventually be thrown out of the solar system forever, just like the "alien" comet 3I/ATLAS.

During the COVID-19 pandemic, the atmosphere temporarily lost its ability to break down methane, leading to a huge spike in the greenhouse gas.

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.

Planting trees on 6.4 million hectares of northern taiga forest could remove 3.9 gigatons of CO2 by 2100 — five times Canada's annual emissions.

Iconic transition species between dinosaurs and birds may have had weird 'teeth' on roof of its mouth and a highly mobile tongue, study reveals

NASA's SPHEREx space telescope detected organic molecules coming off comet 3I/ATLAS as the interstellar visitor made its closest approach to Earth in December.

A tunnel system discovered in a Stone Age tomb in Germany suggests medieval people created hiding places for their cultic rituals.

Decades of overfishing and habitat degradation led to huge declines in freshwater biodiversity in China's longest river, but there are signs of recovery after a fishing ban was implemented in 2021.

The earliest black holes in the universe may not have disappeared from Hawking radiation after all, new research hints. Instead, they fed on the energy of the ancient cosmos to grow supermassive.

Astronomers have spotted an unusual 'inside-out' planetary system where a rocky world seems to have formed far beyond the realm typically reserved for gas giants.

A figure commonly used to compare the risk of death from pregnancy compared with the risk of death from abortion might be based on outdated data, a new study suggests.

The carbon emissions of the world's biggest greenhouse gas emitter have plateaued for nearly two years.

The National Science Foundation's massive IceCube neutrino detector at the South Pole just got a major new upgrade, which promises to take the search for "ghost particles" to a new level.

A new vaccine design uses folded DNA to steer the immune system toward producing the rare immune cells needed to make protective antibodies against HIV.

The delicate gold ring was made sometime in the Middle Ages and may have belonged to a high-status woman.

Scientists hope to probe the nature of general relativity through a possible pulsar found in the center of the Milky Way, near a supermassive black hole.

If proven effective in humans, the vaccine could complement standard therapies for HPV-driven cancer, as well as inform the design of therapeutic vaccines for other diseases.

New research using a space-time phenomenon predicted by Einstein presents evidence that the invisible backbone of the universe may be much "fuzzier" than we realized.

An analysis of peatland soil samples and satellite images has found that wildfires on Alaska's North Slope are more frequent and severe now than they were at any point over the past 3,000 years.
