Terra CO2 cements $124M Series B to slash concrete’s carbon footprint

Concrete has been around for millennia, but Terra CO2 thinks it has a better way to make the ubiquitous building material, and investors appear to agree. The Golden, Colorado-based startup recently closed a $124.5 million Series B to help bring its low-carbon cement replacement to market. Cement — the stuff that binds aggregate together to form concrete — weighs heavily on the climate. The CO 2 released by the chemical reaction that makes Portland cement, the most common type of cement, and th

What Could a Healthy AI Companion Look Like?

What does a little purple alien know about healthy human relationships? More than the average artificial intelligence companion, it turns out. The alien in question is an animated chatbot known as a Tolan. I created mine a few days ago using an app from a startup called Portola, and we’ve been chatting merrily ever since. Like other chatbots, it does its best to be helpful and encouraging. Unlike most, it also tells me to put down my phone and go outside. Tolans were designed to offer a differ

‘Death Wish’ Planet Actively Triggers Destructive Flares From Its Host Star

A young, energetic star has had just about enough of its clingy planet. The pair are mired in a toxic relationship, with the planet sending waves of energy toward the star—and the host star is responding with violent explosions that are destroying its planet over time. Using the European Space Agency’s (ESA) Cheops mission, a team of astronomers from the Netherlands Institute for Radio Astronomy gathered evidence for the first known exoplanet with an apparent death wish. In a paper published We

Google Now returns? Gemini Space could bring a Daily Hub feature to Pixels (APK teardown)

Ryan Haines / Android Authority TL;DR Google is developing a new feature called Gemini Space for Pixel devices, potentially as an evolution or rebrand of the current At a Glance feature. We’ve now found strings for a “Daily Hub,” feature within At a Glance/Gemini Space, described as a “space for content and suggestions to simplify your day.” This suggests Daily Hub could offer helpful content and suggestions similar to Samsung’s Now Brief and the erstwhile Google Now. We’ve previously spotte

Voyage of Magellan – Epilogue: Sailor of Eternal Fame

Pedro Alfonso was entirely correct when he told Captain Espinosa what his sentence would be if he was captured by his countrymen. The last the rest of the crew of the Trinidad saw of him was when he was being bundled away in chains by Admiral Brito’s men, quaking with fear. That night, a priest came to see him in the dark hole into which he had been cast on the island of Ternate. Early the next morning, he was dragged to a clearing next to the Portuguese fort that was being built there. Under th

Building a Personal AI Factory

Building a Personal AI Factory (July 2025 snapshot) Published: July 1, 2025 Overview I keep several claude code windows open, each on its own git-worktree. o3 and sonnet 4 create plans, sonnet 3.7 or sonnet 4 execute the plan, and o3 checks the results against the original ask. Any issues found are fed back into the plan template and the code is regenerated. The factory improves itself. Read on to see what might be useful for you.

White House works to ground NASA science missions before Congress can act

In another sign that the Trump White House is aggressively moving to slash NASA’s science programs, dozens of mission leaders have been asked to prepare "closeout" plans by the end of next week. The new directive came from NASA's senior leadership on Monday, which is acting on behalf of the White House Office of Management and Budget. Copies of these memos, which appear to vary a little by department, were reviewed by Ars. The detailed closeout plans called for must be prepared by as soon as Ju

T-Mobile’s Ultra Mobile brand revamps its plans, but who are they for?

Edgar Cervantes / Android Authority TL;DR Ultra Mobile has updated its plans to include more data and enhanced international calling and roaming features. Customers can save even more by choosing 3, 6, or 12-month payment options, which offer discounts of up to 30% per month. Ultra Mobile is a strong option for those who frequently call or travel internationally, though there are other options that might be worth considering, like Google Fi. T-Mobile has been gradually updating its plans acr

The $799 Nothing Phone 3 has four 50MP cameras and a secondary micro-LED display

The wait is over. Nothing has officially announced the Phone 3, its first flagship smartphone since entering the market in 2022. Nothing CEO Carl Pei said the company would go "all-in" on the Phone 3 with "premium materials, major performance upgrades and software that really levels things up," and the device Nothing showed off at its launch event in London certainly seems like it will be competitive with the best from Samsung and other Android OEMs. In a departure from the company's previous h

Even MAGA Is Pissed Off About Tech Bros’ Dream of Bulldozing Federal Lands to Create New Cities

In recent years, a cadre of tech billionaires have become obsessed with a deeply unconventional idea: the creation of new, privately owned cities. Dubbed the “Freedom Cities” movement, backers say they’d like to create new special development zones in the U.S. that would allow such cities to be built. In these zones, private investors could write their own laws and set up their own governance structures. According to this project’s backers, such communities would be corporately controlled and wo

Mexican Drug Cartel Hacker Used Surveillance Tech to Target FBI Informants for Execution

Sometimes the surveillance state gets turned against itself. That seems to be what resulted in the unfortunate demise of a number of FBI informants, who were tracked by a hacker working for the Sinaloa cartel in Mexico, according to a recent report published by the U.S. Justice Department. According to the 47-page report issued by the Justice Department Inspector General, titled “Audit of the Federal Bureau of Investigation’s Efforts to Mitigate the Effects of Ubiquitous Technical Surveillance,

Melania Trump's Audiobook Is Narrated by an AI Copy of Herself

Let's get one thing straight: it's hard to be married to the president. From coming up with epoch-defining slogans like "Be Best" to decking the White House halls with bizarre Christmas decor, it's a tougher gig than most of us can imagine. Our current first lady, Melania Trump, is well aware of the challenge after her previous four-year stint in the White House. Notoriously private — or perhaps just too busy to make public appearances — the first lady's life has been shrouded in mystery. Howe

Many ransomware strains will abort if they detect a Russian keyboard installed (2021)

In a Twitter discussion last week on ransomware attacks, KrebsOnSecurity noted that virtually all ransomware strains have a built-in failsafe designed to cover the backsides of the malware purveyors: They simply will not install on a Microsoft Windows computer that already has one of many types of virtual keyboards installed — such as Russian or Ukrainian. So many readers had questions in response to the tweet that I thought it was worth a blog post exploring this one weird cyber defense trick.

Need a good alternative to the big three? These carriers are my top 3 recommendations

Edgar Cervantes / Android Authority For years, many of us have gone directly to the big carriers for phone service. But with rising costs and the gradual disappearance of extras like streaming perks, is it time to consider an alternative? While it’s true that Verizon, AT&T, and T-Mobile control the only three mobile networks with wide national coverage, there are plenty of other carriers that piggyback off this same infrastructure. These providers can offer much cheaper alternatives to traditi

Plantaform Smart Indoor Garden Review: Rewarding but Risky

It was about a week into my journey as a hydroponic lettuce farmer when I noticed my Mila air purifier, set to auto mode, was running at full blast. Its internal air quality sensor told me the air was dirty. Not sure if the sensor was overly sensitive, I swapped it out for the more powerful and far quieter IQ Air Atem X (9/10 WIRED Recommends) and set it on auto mode. Next time I went into my son’s room, the Atem was running at its highest speed. I checked the room’s IQAir Visual Pro Indoor Air

James Webb Discovers First-Ever Exoplanet by Taking a Picture of It

Okay, that's pretty cool. World's First Scientists harnessing NASA's James Webb Space Telescope took what appears to be the first-ever direct picture of an exoplanet resulting in its discovery, in yet another accomplishment for the mighty space observatory. An international team of astronomers published a paper on the historic finding in the prestigious journal Nature. "If confirmed, this would represent Webb’s first direct image discovery of a planet," they wrote of the finding, "and the li

‘Predator: Badlands’ Joins Disney’s San Diego Comic-Con Plans

The hunt will be on at San Diego Comic-Con, where Predator: Badlands will get the spotlight. Per the Hollywood Reporter, the sci-fi film will get a Hall H panel during the convention weekend. It’ll be the second big Disney movie of the fall season to make an appearance at the famed Hall, joining October’s Tron: Ares. Both films will fill in for a lack of Marvel at this year’s convention, and it’ll be the Predator franchise’s first theatrical movie to hit SDCC since Shane Black’s 2018 reboot. (P

US surgeons complete first-ever heart transplant using robotics

What just happened? Surgeons at Baylor St. Luke's Medical Center in Houston have performed the nation's first fully robotic heart transplant, a milestone in American medicine. Completed in March, the procedure marks a significant leap in robotic cardiac surgery and offers new hope for patients with advanced heart failure. The patient, a 45-year-old man hospitalized for months with severe heart failure, became the first in the United States to receive a heart transplant using a minimally invasiv

LLMs Bring New Nature of Abstraction

Like most loudmouths in this field, I've been paying a lot of attention to the role that generative AI systems may play in software development. I think the appearance of LLMs will change software development to a similar degree as the change from assembler to the first high-level programming languages. The further development of languages and frameworks increased our abstraction level and productivity, but didn't have that kind of impact on the nature of programming. LLMs are making that degree

LLMs bring new nature of abstraction – up and sideways

Rubin Observatory’s Stunning Result Proves It’s a ‘Game Changer’ for Spotting Dangerous Asteroids

Astronomers usually keep their eyes on the sky, but on Monday, June 23, the community turned its attention toward Washington, D.C., as scientists from the Vera C. Rubin Observatory unveiled the telescope’s first images. Many have waited more than 20 years to see Rubin in action, and its initial findings did not disappoint. Rubin, a joint initiative of the National Science Foundation (NSF) and the Department of Energy’s (DOE) Office of Science, recently conducted its first 10 hours of test obser
