The city of Rome has been inhabited continuously for 14,000 years—long before it became known by its current name. While this makes the Italian capital city a world capital in terms of archaeology and ancient history, the centuries and centuries of construction make it difficult to study the city’s ancient beginnings. Enter Gabii, an ancient Roman city 11 miles east of Rome you’ve probably never heard of unless you’re an expert in the field. Built around 250 BCE with evidence that some parts may be even older,…
“Unable to scrape Reddit directly, they mask their identities, hide their locations, and disguise their web scrapers to steal Reddit content from Google Search,” Lee said. “Perplexity is a willing customer of at least one of these scrapers, choosing to buy stolen data rather than enter into a lawful agreement with Reddit itself.” On Reddit, Perplexity pushed back on Reddit’s claims that Perplexity ignored requests to license Reddit content. “Untrue. Whenever anyone asks us about content licensing, we explain that Perplexity, as an application-layer company, does not train AI models on content,” Perplexity said. “Never has. So, it is impossible…

In a world first, researchers at the University of British Columbia (UBC) in Canada successfully transplanted a human donor kidney that they artificially swapped from someone with type-A blood to the universal type-O. The breakthrough may pave the way for the creation of a universal donor blood supply, as well as the ability to pull off similar results with other vital organs. The riskiest and often most difficult part of an organ transplant procedure is the distinct possibility that a patients’ body will reject the organ…
OpenAI has acquired Software Applications Incorporated (SAI), perhaps best known for the core team that produced what became Shortcuts on Apple platforms. More recently, the team has been working on Sky, a context-aware AI interface layer on top of macOS. The financial terms of the acquisition have not been publicly disclosed. “AI progress isn’t only about advancing intelligence—it’s about unlocking it through interfaces that understand context, adapt to your intent, and work seamlessly,” an OpenAI rep wrote in the company’s blog post about the acquisition. The post goes on to specify that OpenAI plans to “bring Sky’s deep macOS integration…

Out of the ashes of a devastating fire, archeologists are uncovering exciting insights into Ohio history. On December 7, 2024, a fire swept through southwestern Ohio’s Overfield Tavern Museum in Troy, destroying several historical items in the museum’s collection. But the fire also presented a unique opportunity: to excavate underneath the more than 200-year-old structure. During the dig, a team of archaeologists uncovered an 1817 50-cent piece, ceramics, and Native American artifacts, and more beneath the charred floorboards. “Thousands of artifacts were recovered and are currently being…
Aiming for LEO … This will be the first flight of Innospace’s HANBIT-Nano launch vehicle, standing roughly 72 feet (22 meters) tall with a diameter of 4.6 feet (1.4 meters). The two-stage rocket is powered by hybrid propulsion, consuming a mixture of paraffin and liquid oxygen. For its debut flight, the rocket will target an orbit about 300 kilometers (186 miles) high with a batch of small satellites from customers in South Korea, Brazil, and India. According to Innospace, HANBIT-Nano can lift about 200 pounds (90 kilograms) of payload into orbit. A new record for rocket reuse. SpaceX’s launch of a…

Whether it’s the sudden threat of an out-of-control vehicle or the nervous wait before a job interview, we all have felt fear’s sudden grip. But could fear actually be contagious? “We are social creatures who learn from others,” says Arash Javanbakht, a psychologist at Wayne State University and author of Afraid: Understanding the Purpose of Fear and Harnessing the Power of Anxiety. Oftentimes, we learn what to fear from other people. So,…
Karoline Leavitt, the White House press secretary, shared a different point of view in an interview with Fox News earlier this week. “I believe there’s a lot of fake outrage right now because nearly every single president who has lived in this beautiful White House behind me has made modernizations and renovations of their own,” Leavitt said. An official White House fact sheet published Tuesday used similar sensationalized language, accusing “unhinged leftists and their Fake News allies” of “clutching their pearls over President Donald J. Trump’s visionary addition of a grand, privately-funded ballroom to the White House.” President Donald Trump…

It leverages AI to analyze what’s on your phone screen,…
To test the contrast however, I first listened to the speaker without its bass bottle. It’s very loud for a small speaker, and in my office I couldn’t cope with the volume turned up past 30 percent. It’s just not an enjoyable listen, sounding shrill and disappointing without any discernible bass. It’s not quite as bad as putting your old iPhone in a cup for extra amplification, but it’s not far off—and at least you can actually drink from the cup afterwards.But we’re here for the bass-boosting bottle, and I can categorically say that the acoustically tuned plastic bottle does…
