Last year 30,000 people moved into central Florida's Polk County — more than to any other county in America. Its largest city has just 112,641 people, living a full 35 miles east of the 3.1 million residents in the metropolitan area around Tampa. But the Associated Press says something similar is happening all over the country: "the rise of the far-flung exurbs." Outlying communities on the outer margins of metro areas — some as far away as 60 miles (97 kilometers) from a city's center — had some of the fastest-growing populations last year, according to the U.S. Census Bureau. Those communities are primarily in the South, like Anna, Texas on the outskirts of the Dallas-Fort Worth metro area; Fort Mill, South Carolina [just 18 miles from North Carolina city Charlotte]; Lebanon, Tennessee outside Nashville; and Polk County's Haines City... [C]ommuting to work can take up to an hour and a half one-way. But [Marisol] Ortega, who lives in Haines City about 40 miles (64 kilometers) from her job in Orlando, says it's worth it. "I love my job. I love what I do, but then I love coming back home, and it's more tranquil," Ortega said. The rapid growth of far-flung exurbs is an after-effect of the COVID-19 pandemic, according to the Census Bureau, as rising housing costs drove people further from cities and remote working allowed many to do their jobs from home at least part of the week... Recent hurricanes and citrus diseases in Florida also have made it more attractive for some Polk County growers to sell their citrus groves to developers who build new residences or stores... Anna, Texas, more than 45 miles (72 kilometers) north of downtown Dallas, is seeing the same kind of migration. It was the fourth-fastest growing city in the U.S. last year and its population has increased by a third during the 2020s to 27,500 residents. Like Polk County, Anna has gotten a little older, richer and more racially diverse. The article points out that in Anna, Texas, "close to 3 in 5 households have moved into their homes since 2020, according to the Census Bureau."

Chances of intelligent life emerging in our Universe "and in any hypothetical ones beyond it" can be estimated by a new theoretical model, reports the Royal Astronomical Society. Since stars are a precondition for the emergence of life, the new research predicts that a typical observer [i.e., intelligent life] should experience a substantially larger density of dark energy than is seen in our own Universe... The approach presented in the paper involves calculating the fraction of ordinary matter converted into stars over the entire history of the Universe, for different dark energy densities. The model predicts this fraction would be approximately 27% in a universe that is most efficient at forming stars, compared to 23% in our own Universe. Dark energy makes the Universe expand faster, balancing gravity's pull and creating a universe where both expansion and structure formation are possible. However, for life to develop, there would need to be regions where matter can clump together to form stars and planets, and it would need to remain stable for billions of years to allow life to evolve. Crucially, the research suggests that the astrophysics of star formation and the evolution of the large-scale structure of the Universe combine in a subtle way to determine the optimal value of the dark energy density needed for the generation of intelligent life. Professor Lucas Lombriser, Université de Genève and co-author of the study, added: "It will be exciting to employ the model to explore the emergence of life across different universes and see whether some fundamental questions we ask ourselves about our own Universe must be reinterpreted." The study was funded by the EU's European Research Council, and published in Monthly Notices of the Royal Astronomical Society. Thanks to long-time Slashdot reader schwit1 for sharing the news.

An anonymous reader shared this report from the Associated Press: Even as Earth sets new heat records, humanity this year is pumping 330 million tons (300 million metric tons) more carbon dioxide into the air by burning fossil fuels than it did last year. This year the world is on track to put 41.2 billion tons (37.4 billion metric tons) of the main heat-trapping gas into the atmosphere. It's a 0.8% increase from 2023, according to Global Carbon Project, a group of scientists who track emissions... This year's pollution increase isn't quite as large as last year's 1.4% jump, scientists said while presenting the data at the United Nations climate talks in Azerbaijan... The continued rise in carbon emissions is mostly from the developing world and China. Many analysts had been hoping that China — by far the world's biggest annual carbon polluting nation with 32% of the emissions — would have peaked its carbon dioxide emissions by now. Instead China's emissions rose 0.2% from 2023, with coal pollution up 0.3%, Global Carbon Project calculated... [Although its growth rate now is "basically flat," O'Sullivan said.] That's nothing close to the increase in India, which at 8% of the globe's carbon pollution is third-largest carbon emitter. India's carbon pollution jumped 4.6% in 2024, the scientists said. Carbon emissions fell 0.6% in the U.S. mostly from reduced coal, oil and cement use. The U.S. was responsible for 13% of the globe's carbon dioxide in 2024. Historically, it's responsible for 21% of the world's emissions since 1950... Twenty-two nations have shown steady decreases in emissions, O'Sullivan said, singling out the United States as one of those. The biggest emission drops from 2014 to 2023 were in the United States, Japan, Germany, the United Kingdom and Ukraine. Europe, which accounts for 7% of the world's carbon pollution, saw its carbon dioxide output drop 3.8% from last year — driven by a big cut in coal emissions. Some interesting statistics from the article: Burning coal, oil, and natural gas is currently emitting 2.6 million pounds (1.2 million kilograms) of carbon dioxide every second..." In the last 10 years, emissions have gone up about 6%. Global carbon emissions are more than double what they were 50 years ago, and 50% more than they were in 1999. "If the world continues burning fossil fuels at today's level, it has six years before passing 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial levels, the limit agreed to at the 2015 climate talks in Paris, said study co-author Stephen Sitch. The Earth is already at 1.3 degrees Celsius (2.3 Fahrenheit), according to the United Nations." Yet "Total carbon emissions — which include fossil fuel pollution and land use changes such as deforestation — are basically flat because land emissions are declining, the scientists said."

Google's transistion to Safe Coding and memory-safe languages "will take multiple years," according to a post on Google's security blog. So "we're also retrofitting secure-by-design principles to our existing C++ codebase wherever possible," a process which includes "working towards bringing spatial memory safety into as many of our C++ codebases as possible, including Chrome and the monolithic codebase powering our services." We've begun by enabling hardened libc++, which adds bounds checking to standard C++ data structures, eliminating a significant class of spatial safety bugs. While C++ will not become fully memory-safe, these improvements reduce risk as discussed in more detail in our perspective on memory safety, leading to more reliable and secure software... It's also worth noting that similar hardening is available in other C++ standard libraries, such as libstdc++. Building on the successful deployment of hardened libc++ in Chrome in 2022, we've now made it default across our server-side production systems. This improves spatial memory safety across our services, including key performance-critical components of products like Search, Gmail, Drive, YouTube, and Maps... The performance impact of these changes was surprisingly low, despite Google's modern C++ codebase making heavy use of libc++. Hardening libc++ resulted in an average 0.30% performance impact across our services (yes, only a third of a percent) ... In just a few months since enabling hardened libc++ by default, we've already seen benefits. Hardened libc++ has already disrupted an internal red team exercise and would have prevented another one that happened before we enabled hardening, demonstrating its effectiveness in thwarting exploits. The safety checks have uncovered over 1,000 bugs, and would prevent 1,000 to 2,000 new bugs yearly at our current rate of C++ development... The process of identifying and fixing bugs uncovered by hardened libc++ led to a 30% reduction in our baseline segmentation fault rate across production, indicating improved code reliability and quality. Beyond crashes, the checks also caught errors that would have otherwise manifested as unpredictable behavior or data corruption... Hardened libc++ enabled us to identify and fix multiple bugs that had been lurking in our code for more than a decade. The checks transform many difficult-to-diagnose memory corruptions into immediate and easily debuggable errors, saving developers valuable time and effort. The post notes that they're also working on "making it easier to interoperate with memory-safe languages. Migrating our C++ to Safe Buffers shrinks the gap between the languages, which simplifies interoperability and potentially even an eventual automated translation."

"The Pentagon's latest report on UFOs has revealed hundreds of new reports of unidentified and unexplained aerial phenomena," reports the Associated Press, "but no indications suggesting an extraterrestrial origin. "The review includes hundreds of cases of misidentified balloons, birds and satellites as well as some that defy easy explanation, such as a near-miss between a commercial airliner and a mysterious object off the coast of New York." Federal efforts to study and identify UAPs have focused on potential threats to national security or air safety and not their science fiction aspects. Officials at the Pentagon office created in 2022 to track UAPs, known as the All-Domain Anomaly Resolution Office, or AARO, have said there's no indication any of the cases they looked into have unearthly origins. "It is important to underscore that, to date, the All-Domain Anomaly Resolution Office has discovered no evidence of extraterrestrial beings, activity, or technology," the authors of the report wrote... Reporting witnesses included commercial and military pilots as well as ground-based observers. Investigators found explanations for nearly 300 of the incidents. In many cases, the unknown objects were found to be balloons, birds, aircraft, drones or satellites. According to the report, Elon Musk's Starlink satellite system is one increasingly common source as people mistake chains of satellites for UFOs. Hundreds of other cases remain unexplained, though the report's authors stressed that is often because there isn't enough information to draw firm conclusions. No injuries or crashes were reported in any of the incidents, though a commercial flight crew reported one near miss with a "cylindrical object" while flying over the Atlantic Ocean off the coast of New York. That incident remains under investigation. In three other cases, military air crews reported being followed or shadowed by unidentified aircraft, though investigators could find no evidence to link the activity to a foreign power. The article points out that the report's publication comes "a day after House lawmakers called for greater government transparency during a hearing on unidentified anomalous phenomena." And it concludes with this quote from Republican Represenative Andy Ogles of Tennessee. "There is something out there. The question is: Is it ours, is it someone else's, or is it otherworldly?"
