Researchers Identify World's Largest Scorpion That Roamed Earth 415 Million Years Ago Authored by Maria Mocerino via Interesting Engineering , The University of Manchester has discovered that the world's largest scorpion, which lived 415 million years ago, was hiding in the museum's collection for 150 years. Since the 1870s, researchers have debated the identity of the strange fossil remains lurking in the Manchester archives. They possessed tiny fragments recovered from sites in England and Wales that puzzled them, but they could not piece them together. Was it a large woodlouse-crustacean? Life reconstruction of Praearcturus gigas. Franz Anthony High Res In the 1980s, some research suggested that a scorpion might be the source of the fossil remains. However, this hypothesis faced challenges due to a lack of fossil evidence of its most distinctive feature: its tail. To resolve the debate, paleontologists conducted a study of the remains using modern imaging and analytical techniques, according to a press release from the University of Manchester . They were "able to build a clearer picture of the animal than was previously possible, which is really exciting." The 3.3-foot-long Praearcturus gigas scorpion now joins the ranks of Earth's ferocious prehistoric beasts, boasting pincers 6.2 inches long. As it roamed the Earth over 400 million years ago, researchers sought to understand the factors that allowed this prehistoric predator to grow to such an astonishing size. The T. Rex of Scorpions According to the study authors, "Along with dinosaurs, mammoths, and other charismatic megafauna, giant arthropods are an iconic symbol of the Earth's deep paleontological history in popular culture." Lead author Dr. Richard J. Howard, Curator of Fossil Arthropods at the Natural History Museum in London, described the imagery often associated with giant arthropods: " Carboniferous rainforests filled with giant millipedes or dragonfly-like insects... but Praearcturus lived at leas...

Getty Images It's amazing how rough the last few months have been for Chipotle Mexican Grill, Inc. ( CMG ). Shares of the stock are down 21% since I ended up downgrading it from a Buy to a Hold in February of this year. The reason for the downgrade was because of margin pressure and valuation concerns for the company. Even though the firm offers investors the chance of attractive growth, profitability is an issue. The good news is that the company has a solid balance sheet that can keep it growing even during these tough times. But in recent months, the company has faced continued challenges on that front and is now facing weakness in some aspects of comparable sales. CMG stock is certainly getting cheaper. But based on how it's valued, I'm not ready to upgrade it to a Buy just yet. Instead, I will keep it rated a Hold in the hopes that the stock will fall further or fundamentals will improve sufficiently so as to justify an upgrade. Times Are Tough I know that anecdotes are not valuable when evaluating such a large enterprise as Chipotle Mexican Grill. However, sometime in the last couple of weeks, I ended up visiting a Chipotle Mexican Grill for the first time in quite a while. I remember, just years ago, when you would have to wait 20 minutes in line at that location. Despite the fact that the location in question is continuing to develop, with a Chick-fil-A currently under construction, traffic at that location seems to be abysmal. There was only one other person ahead of me despite it being early afternoon when I would expect a line. The good news for the company is that this is not indicative of the broader business. Since I last wrote about the company, the only new data that has come out involves the first quarter of the 2026 fiscal year. And what that does show is continued top-line growth. Author - SEC EDGAR Data In the chart above, you can see precisely what I mean. Revenue of $3.09 billion ended up beating out the $2.88 billion reported a year earlier. T...

We could see Anthropic’s IPO within weeks, as that company recently confidentially filed its IPO prospectus with the SEC . There have been reports that OpenAI is looking to confidentially file its IPO prospectus as well. With the aggregate valuations of these companies set to potentially exceed $3.5 trillion, these IPOs are almost guaranteed to have an outsized effect on markets. Interestingly, though, S&P Dow Jones Indices has decided not to change its rules to fast-track the inclusion of these newly birthed mega caps into the S&P 500. However, SpaceX, OpenAI, and Anthropic could see inclusion into the Nasdaq 100 as early as 15 days after their respective IPOs if various eligibility criteria are met following rule changes vis-à-vis that index, rule changes widely interpreted as an accommodation for these companies. This means that the Nasdaq 100, an index that is already heavily over-indexed (pun intended) to the fortunes of big tech, will become that much more so post these mega IPOs. If things go well, that means leveraged upside for investors in popular ETFs like Invesco QQQ Trust ( QQQ ); however, if things don’t go so well, leverage famously works to the downside. What to Expect Post IPO The consensus seems to be that inclusion in the Nasdaq 100 should produce upside for these companies in the short term as passive inflows from index investors create buying pressure (see here and here ). However, my contention is that these expectations are likely overstated in terms of magnitude and especially duration – i.e., the degree to which there might be a pop from these pressures and how long it could last. There are a growing number of investors who are in the camp that things like company fundamentals, valuations, and the like don’t matter much anymore as the investment landscape has switched from acti...

A joint research collaboration between researchers at the University of Illinois at Urbana-Champaign (UIUC), UC Berkeley, and the open source AI-native vector database platform Chroma unveiled Harness-1 , a 20-billion parameter open-source search agent built atop OpenAI's gpt-oss-20B open source model that fundamentally redesigns how AI executes complex retrieval tasks. Harness-1 achieves a massive leap in performance, scoring 73% average on its ability to recall relevant information correctly from a curated dataset, outperforming even GPT-5.4 (70.9%) and the next, most accurate open source search agent, Tongyi DeepResearch 30B , by 11.4 percentage points. (While GPT-5.5 has also been out for more than a month, the researchers didn't test against this model as it wasn't available when they were building theirs.) Crucially for developers, the model and its environment are available immediately under the highly permissive Apache 2.0 license and model code/weights on Hugging Face . Harness-1 also serves as proof-of-efficacy of another effort, Tinker , the distributed, web-based AI model training and fine-tuning API developed by Thinking Machines. Tinker was used specifically to train and run inference for Harness-1, highlighting how interactive infrastructure is actively enabling the next generation of autonomous models. So how did the researchers do it? Benchmarks Decoded (and Why Harness-1 Could Help Enterprises Tremendously) To actually put these models to the test, the researchers evaluated Harness-1 and its competitors across eight highly complex search benchmarks. Rather than asking simple trivia questions, these tests required the AI to act like a real researcher sifting through diverse, dense data sources. The benchmarks spanned several different domains, including open web searches, complex financial filings from the SEC, technical patent databases from the USPTO, and "multi-hop" question-answering tasks where the AI had to logically piece together scattered c...

watch now VIDEO 1:31 01:31 Things have changed in the market for the worse, says Jim Cramer Mad Money with Jim Cramer CNBC's Jim Cramer said Monday that a series of mounting risks has made him significantly more cautious on stocks. "I am not that bullish," the " Mad Money " host said. "My bullishness can wait. I think you will get a better time to buy than right now." The caution comes as several pillars of Cramer's bullish outlook have come under pressure. A surprisingly strong jobs report has reduced the likelihood of Federal Reserve rate cuts, while the looming SpaceX IPO, weakness in Apple, and the prospect of additional AI-related fundraising have raised new questions about whether the market can sustain its recent rally. "Things have changed. For the worse," Cramer said. "There's a shroud over this market and you ignore it at your own peril." At the top of Cramer's list is Friday's surprisingly strong employment report, which he said undermines the case for rate cuts this year. Cramer said expectations for one or two rate cuts had been a key pillar of his bullish thesis. Now, he believes the report was strong enough that "you could argue we might need a rate hike to cool the economy, not a rate cut to turn the temperature up." He also expressed concern about the upcoming SpaceX IPO. While demand for the offering appears robust, Cramer warned that an overly enthusiastic debut could ultimately backfire if the stock surges to unsustainable levels before falling sharply. "What happens if it opens too high simply because there's not enough stock to go around, and then we watch a sickening decline after that moment?" he said. "That could be very bad. It would color things very negatively maybe for some time." Apple is another source of worry. Cramer said he hoped the company's Worldwide Developers Conference would serve as a catalyst for the stock, but shares instead moved lower. "Apple is a leader, maybe the leader, and I don't want to lose the leader of this stock...
