This Unlikely Chemical Could Be a Powerful Weapon Against Climate Change

Year after year, humans pump more carbon dioxide (CO2) into the atmosphere than nature can remove, fueling global warming. As the need to mitigate climate change becomes increasingly urgent, scientists are developing ways to actively remove CO2 from the atmosphere in addition to cutting emissions. One of the biggest hurdles to scaling current carbon capture technologies is the vast amount of energy they consume, but what if there was an alternative that uses an abundant, cheap power source?

Dolby Atmos FlexConnect Lets You Place Speakers Anywhere

For years, there have been just two options for better TV sound: A traditional, AV receiver-based home theater system or a soundbar. The AV receiver route is undeniably the best way to go for a truly cinematic experience, but only the most diehard audiophiles are willing to deal with hulking metal boxes, yards of speaker wire, and a minimum of five speakers (plus a subwoofer) that must be placed just so. That’s before you delve into the often arcane settings needed for peak performance. Soundb

Earth models can predict the planet’s future but not their own

arstechnica.com Unknown 2025-10-20 21:00:12

In the 1960s, meteorologist Edward Lorenz was running weather simulations on an early computer system when he realized that a small rounding difference led to extremely divergent weather predictions. He later called this idea the butterfly effect to communicate that small changes in initial conditions, like a butterfly flapping its wings in Nepal, could produce wildly different outcomes, like rain in New York. But better understanding those initial conditions and how the biological world couple

Misunderstood “photophoresis” effect could loft metal sheets to exosphere

Most people would recognize the device in the image above, although they probably wouldn't know it by its formal name: the Crookes radiometer. As its name implies, placing the radiometer in light produces a measurable change: the blades start spinning. Unfortunately, many people misunderstand the physics of its operation (which we'll return to shortly). The actual forces that drive the blades to spin, called photophoresis, can act on a variety of structures as long as they're placed in a suffic

The Ultimate Dolby Atmos Experience Might Be In Your Car

It’s fair to say that no five people crammed into a compact SUV have been more blissfully enthralled on a country drive than my wife’s family and I on one particular mid-summer Sunday. It wasn’t just the silky smooth performance of the Cadillac Optiq, or even its incredible 19-speaker AKG sound system, but an x-factor pushing our driving experience beyond the sum of their parts: Dolby Atmos Music. If you haven't heard it in a vehicle like this, you might think I'm joking. Everyone has probably

The most otherworldly, mysterious forms of lightning on Earth

news.ycombinator.com Unknown 2026-01-23 12:49:31

Our atmosphere is like one big electrical circuit: Thunderstorms are the batteries that charge it up, and lightning is the current flowing through it. On the ground we see evidence of this circuit when lightning cracks and strikes the ground, or when it lights up deep inside a thundercloud, but high above the clouds lies a secret electrical zoo full of sprites, elves, and jets. These fantastical terms refer to light displays called transient luminous events or TLEs that occur in Earth’s upper a

What Problems to Solve (1966)

What Problems to Solve - By Richard Feynman A former student, who was also once a student of Tomonaga’s, wrote to extend his congratulations. Feynman responded, asking Mr. Mano what he was now doing. The response: “studying the Coherence theory with some applications to the propagation of electromagnetic waves through turbulent atmosphere… a humble and down-to-earth type of problem.”

Scientists Reveal Easy Three-Step Plan to Terraform Mars

futurism.com Unknown 2026-03-15 00:45:29

Terraforming, the act of radically transforming a planet's climate and environment to make it suitable for human habitation, currently belongs to the realm of science-fiction. But it's possible, at least in theory, and the idea of terraforming our nearest candidate planet for off-world colonization, Mars, has captivated us for generations. But how would we even begin to pull off such a monumental feat of engineering? You can basically boil it down to three simple steps, argue the authors of a r

Astronomers create first 3D map of a hellish alien planet's atmosphere

The big picture: Nearly 6,000 exoplanets have now been confirmed in the vast expanse of the Milky Way galaxy. Some are believed to have the potential to harbor life, while others are so hostile that they make Venus seem mild by comparison. One such planet is the ultra-hot Jupiter known as WASP-121b, nicknamed Tylos – a world so extreme it defies expectations. Located around 900 light-years away in the Puppis constellation, Tylos orbits its parent star at an absurdly close distance, completing a
