A report from Reuters claims that scientists in China have created a prototype of a machine that could eventually be used to produce semiconductor chips capable of powering artificial intelligence. Sources told the publication that a team in Shenzhen completed the prototype of an extreme ultraviolet lithography machine earlier this year and it is allegedly now undergoing testing. The EUV machine was reportedly made by former engineers from Dutch semiconductor supplier ASML. Reuters states that China is targeting production of its own EUV chips beginning in 2028, although other experts have projected 2030 as a more likely date.EUV is a…

A mysterious, spider-like structure lurking on Jupiter’s fourth-largest moon, Europa, may finally have a proper explanation nearly 30 years after it was discovered. The arachnid imposter has also been given a demonic new name.In March 1998, NASA’s Galileo spacecraft — which studied Jupiter and its major moons between 1995 and 2003 — made a close flyby of Europa, a frozen ocean moon often considered one of the most likely places for extraterrestrial life to exist in the solar system. During this flyby, the probe mapped out a roughly 13.7-mile-wide (22 kilometers) impact structure, dubbed Manannán Crater, on the moon’s icy…

Physicists at the University of Amsterdam came up with a really cool bit of Christmas decor: a miniature 3D-printed Christmas tree, a mere 8 centimeters tall, made of ice, without any refrigeration equipment or other freezing technology, and at minimal cost. The secret is evaporative cooling, according to a preprint posted to the physics arXiv. Evaporative cooling is a well-known phenomenon; mammals use it to regulate body temperature. You can see it in your morning cup of hot coffee: the hotter atoms rise to the top of the magnetic trap and “jump out” as steam. It also plays a role…

This time of year makes me miss being a kid and unwrapping a cool new RPG I could then spend the winter quietly toiling through. Not an internet guide in sight. Just a fan living in the moment. So I’m always on the lookout to see what games are getting discounted during the holiday sell-off in case there are one or two things I can pick up and add to my physical collection for cheap. I might even wrap them and put them in a stocking or under the tree and pretend they’re from Santa. Here are a few of…

Space is full of unsolved mysteries, and a team using NASA’s James Webb Space Telescope have recently turned up a doozy. “I remember after we got the data down, our collective reaction was ‘What the heck is this?’ It’s extremely different from what we expected,” said Peter Gao of the Carnegie Earth and Planets Laboratory in Washington, a co-author on the study.The researchers found an exoplanet dubbed PSR J2322-2650b that orbits a small, dense star emitting electromagnetic radiation known as a pulsar. They are an example of a black widow system, where a rapidly spinning pulsar is paired with a…

Pumas in Patagonia are preying on penguins — and it’s changing how the big cats interact with each other.The pumas in question reestablished themselves in an Argentinian national park that housed a penguin breeding colony — and the cats promptly began eating the birds. Now, it turns out the normally solitary cats that eat the penguins are tolerating each other more often than expected, new research published Wednesday (Dec. 17) in the Proceedings of the Royal Society B reports.The findings suggest that reintroductions like these can have surprising knock-on effects.

I first encountered LetPot as a brand earlier this year, while testing its LPH-SE Senior hydroponic growing system for my guide to the best indoor gardening systems. Positioned as alternatives to the long-beloved OG Aerogarden tabletop hydroponic systems, LetPot’s countertop gardens (which are popular enough to have their own subreddit) allow you to grow any seeds you’d like—no proprietary pods needed—using inexpensive baskets and sponges that are ubiquitous on Amazon and run about 20 cents each. (LetPot’s sets come with enough baskets and sponges to get you started, but no seeds.) I regularly recommend LetPot’s version as the best budget…

Creators and publishers have long worried about Meta’s ability to throttle links to outside content. Now, the company is testing out a new scheme that effectively puts link-sharing behind a paywall for creators on Facebook.Under the test, a Meta Verified subscription will determine how many links a creator can share another profile per month. According to a screenshot shared by social meda consultant Matt Navarra, creators in the test recently received a notification from Meta informing them that “certain Facebook profiles without Meta Verified, including yours, will be limited to sharing links in 2 organic posts per month.”Meta is making…

James Ohlen joined Wizards of the Coast back in 2019 after a 22-year stint at BioWare to create a new IP for the Hasbro-owned tabletop gaming company. Six years later, after cofounding Archetype Entertainment to ship a very Mass Effect-looking RPG called Exodus, he’ll no longer be head of the studio when the game eventually ships in 2027. “At this stage, James felt his work on the game was complete and that the polishing and tuning were in great hands with the team,” Hasbro VP of Communications, Abby Hodes, told Bloomberg in a statement. She added that Ohlen asked to…

By USGS Landsat Missions The U.S. Geological Survey, in cooperation with NASA, has named the new Landsat Science Team that will support the world’s longest-running Earth observation mission for a planned 2026-2030 term.  The team brings together experts from universities, private industry, and federal and international agencies to help the U.S. Geological Survey (USGS) and NASA ensure Landsat continues delivering trusted, publicly available data that supports disaster response, agricultural management, water resources, land stewardship, and national security.   The Landsat Science Team supports the USGS and NASA in maintaining scientific integrity, data quality, and mission continuity across the Landsat program. Their work…
