Written by Noah Martin, Ph.D. student and Candice Bedford, Research Scientist at Purdue University While much of Perseverance’s work focuses on ancient rocks that record Mars’ long-lost rivers and lakes, megaripples offer a rare opportunity to examine processes that are still shaping the surface today. Megaripples are sand ripples up to 2 meters (about 6.5 feet) tall that are mainly built and modified by wind. However, when water in the atmosphere interacts with dust on the ripple surface, a salty, dusty crust can form. When this happens, it is much harder for the wind to move or shape the megaripple.…
Google has filed a lawsuit to protect its search results, targeting a firm called SerpApi that has turned Google’s 10 blue links into a business. According to Google, SerpApi ignores established law and Google’s terms to scrape and resell its search engine results pages (SERPs). This is not the first action against SerpApi, but Google’s decision to go after a scraper could signal a new, more aggressive stance on protecting its search data. SerpApi and similar firms do fulfill a need, but they sit in a legal gray area. Google does not provide an API for its search results, which…

There are few better sights in nature than December’s night sky. Bright stars like Betelgeuse, Capella, Aldebaran, Sirius and the stars of Orion’s Belt dominate the night sky after dark, but over the two weeks from Dec. 20, 2025 to Jan. 4, 2026, you can follow some unique astronomical events.As seen from the Northern Hemisphere this year, a crescent moon will curl up in the western sky just before Christmas Day, before gliding past Saturn and the Pleiades. Meanwhile, Jupiter shines as a bright “Christmas Star” in the east right after dark.Add two meteor showers and a full “Wolf Supermoon”,…
Much of the imagery is familiar from previous releases, and includes things like a photo of a stuffed tiger, a photo of a framed Times of London cover of Princess Diana placed at the back of a closet, photos of the many paintings of nude women in Epstein’s townhouse, and framed photos of Epstein associates like Trump and Woody Allen.Volume 2The second volume contains 574 photos and one four-second video.

The superhero movie rumor mill is nothing new, but Avengers: Doomsday has been a bigger lightning rod for speculation, uncertainty, and misinformation than the average Marvel Cinematic Universe film. Part of this is because Marvel has been keeping the movie under wraps with enigmatic teases and trailers that you probably don’t know are (supposed to be) playing ahead of Avatar: Fire and Ash if you’re not tuned into the space. But even if you are paying attention to Doomsday’s hype cycle, it’s hard to trust that the information, images, or clips you’re seeing are even real. Part of this is…
In October 2024, news broke that Facebook parent company Meta had cracked an “impossible” problem that had stymied mathematicians for a century.In this case, the solvers weren’t human.An artificial intelligence (AI) model developed by Meta determined whether solutions of the equations governing certain dynamically changing systems — like the swing of a pendulum or the oscillation of a spring — would remain stable, and thus predictable forever. You may like The key to the problem was finding Lyapunov functions, which determine the long-term stability of these systems.Meta’s work made headlines and raised a possibility once considered pure fantasy: that AI…
Well, they’re finally here. On Friday, the United States Department of Justice released a large trove of files related to infamous convicted sex offender Jeffrey Epstein. The release comes just eight hours before the deadline mandated by the Epstein Files Transparency Act, which President Donald Trump signed into law last month.For the Trump administration, Epstein has been “a guy that never dies,” in the words of Trump himself. Since the start of Trump’s second term, the DOJ and FBI have been scouring the agencies’ investigative holdings and releasing portions of that in spurts. While Friday’s release marks the largest trove…
