Innovative new exhibition exploring the art, culture, and science of psychedelics opens at ROM - Royal Ontario Museum (ROM)

A reporting trip to a sauna conference in Oslo found NPR's Will Stone in a sauna with his clothes and recording gear. In this reporter's notebook, he explains how he investigates the science behind wellness claims. ELISSA NADWORNY, HOST: NPR's Will Stone reports on that line between proven medical treatments and alternative health practices. WILL STONE, BYLINE: If you're envisioning study subjects smoking weed and sipping free booze, then you have a pretty good picture of this experiment. NADWORNY: Weed versus alcohol, metabolic medicine and, yes, the science of sauna. STONE: It's basically a chance for the sauna world to nerd out. NADWORNY: In September, Will Stone traveled to Oslo, Norway, for the International Sauna Congress. STONE: You have scientists, business operators, advocates. They're all here for a few days to talk about everything from the health benefits to the finer points of sauna culture. NADWORNY: The program included party hopping and heat treatments in, quote, "floating sauna villages. " So for this week's Reporter's Notebook, I wanted to talk to Will about arguably the toughest assignment at NPR. I mean, come on. You got in a sauna in Oslo?

Live Science spoke with neuroscientist Argel Aguilar-Valles about recent research exploring psychedelics as a treatment for mild head trauma.

Gomez's Hamburger System. This artist's impression of the Gomez's Hamburger system shows the stacked layers of gas and dust as they rotate around a young star. ALMA observations reveal a direct view of its vertical structure at millimeter wavelengths, allowing astronomers to map the location of the millimeter-sized dust grains and several different gas-phase molecules, which have arranged themselves into distinct levels.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) were surprised to discover the earliest phases of giant planet formation between the dense layers of gas and dust in the "Gomez's Hamburger" system, referred to as GoHam.

The ESA's Euclid Space Telescope has discovered its first comet, a result that's not part of its primary mission. The telescope was launched at the beginning of July, 2023, and its mission is to observe about 1.5 billion galaxies out to redshift z=2, which corresponds to seeing around 10 billion years into the past. The goal is to measure the redshift of a massive amount of galaxies, to shed light on the expansion history of the Universe and the force that drives it, dark energy. The space telescope has observed other comets, but this is the first time it's discovered one. The comet was found in multiple images captured between September 16th and 24th, 2026. For a telescope built to take deep images of distant galaxies, discovering a rapidly moving comet in the Milky Way is a surprising bonus.

If successful, bits of dust, soil and rocks from Phobos will arrive on Earth in 2031. “There’s a lot of adrenaline and a lot of excitement and a lot of wow,” said NASA astrophysicist Tom Statler, who’s involved with the project. Japan has an edge going in, with two asteroid sample returns already under its cosmic belt. Phobos is a lumpy, potato-shaped rock just 14 miles (22 kilometers) or so across. Examining pieces of it can explain how Mars’ moons — and possibly moons elsewhere — came to be. Dubbed MMX for Martian Moons Exploration, the $578 million mission features a hefty 5-ton spacecraft that should reach Mars by late next summer. It will sync up with Phobos’ tight orbit around the red planet, before ejecting the French-German rover that’s named Idefix after the white terrier in the Asterix comics. No bigger than a microwave oven, Idefix will plop onto Phobos by itself, bouncing for several minutes before coming to a halt in the moon’s extraordinarily low gravity. The four-wheeled rover is designed to right itself if it lands upside down. All bets are off, though, if it sinks into soft soil or gets wedged between rocks, said the French Space Agency’s Julien Baroukh.

The latest chemistry news, including important research advances, business and policy trends, chemical safety practices, career guidance, and more. In 2025 scientists put the methane-sensing capabilities of 12 spectral-imaging satellites to the test. Some were designed specifically to measure atmospheric methane; others were repurposed for the task. Now the researchers have shared their results: each of the satellites can be used to detect methane, but some are better than their counterparts for quantifying the potent greenhouse gas (Nature 2026, DOI: 10.1038/s41586-026-11115-0).
