In the 1960s, meteorologist Edward Lorenz was running weather simulations on an early computer system when he realized that a small rounding difference led to extremely divergent weather predictions. He later called this idea the butterfly effect to communicate that small changes in initial conditions, like a butterfly flapping its wings in Nepal, could produce wildly different outcomes, like rain in New York.
But better understanding those initial conditions and how the biological world couples with the atmospheric one can provide better predictions about the future of the planet—from where umbrellas may be most needed in a given season to where electricity needs might sap the grid.
Today, computers are much more powerful than when Lorenz was working, and scientists use a special kind of simulation that accounts for physics, chemistry, biology, and water cycles to try to grasp the past and predict the future. These simulations, called Earth system models, or ESMs, attempt to consider the planet as a system made up of components that nudge and shove each other. Scientists first developed physical climate models in the 1960s and 1970s, and became better at integrating atmospheric and ocean models in subsequent years. As both environmental knowledge and computing power increased, they began to sprinkle in the other variables, leading to current-day ESMs.

Since 2022, Republican lawmakers in Congress and state attorneys general have sent letters to major banks, pension funds, asset managers, accounting firms, companies, nonprofits, and business alliances, putting them on notice for potential antitrust violations and seeking information as part of the Republican pushback against “environmental, social and governance” efforts such as corporate climate commitments.
“This caused a lot of turmoil and stress obviously across the whole ecosystem,” said Denise Hearn, a senior fellow at the Columbia Center on Sustainable Investment. “But everyone wondered, ‘OK, when are they actually going to drop a lawsuit?’”

Words have meaning. Proper word selection is integral to strong communication, whether it's about relaying one’s feelings to another or explaining the terms of a deal, agreement, or transaction.
Language can be confusing, but typically when something is available to "buy," ownership of that good or access to that service is offered in exchange for money. That’s not really the case, though, when it comes to digital content.
Often, streaming services like Amazon Prime Video offer customers the options to “rent” digital content for a few days or to “buy” it. Some might think that picking "buy" means that they can view the content indefinitely. But these purchases are really just long-term licenses to watch the content for as long as the streaming service has the right to distribute it—which could be for years, months, or days after the transaction.

The US Centers for Disease Control and Prevention descended into turmoil this week after Health Secretary and zealous anti-vaccine advocate Robert F. Kennedy Jr. ousted the agency's director, Susan Monarez, who had just weeks ago been confirmed by the Senate and earned Kennedy's praise for her "unimpeachable scientific credentials."
It appears those scientific chops are what led to her swift downfall. Since the Department of Health and Human Services announced on X late Wednesday that "Susan Monarez is no longer director" of the CDC, media reports have revealed that her forced removal was over her refusal to bend to Kennedy's anti-vaccine, anti-science agenda.
The ouster appeared to be a breaking point for the agency overall, which has never fully recovered from the public pummeling it received at the height of the COVID-19 pandemic. In its weakened position, the agency has since endured an onslaught of further criticism, vilification, and misinformation from Kennedy and the Trump administration, which also delivered brutal cuts, significantly slashing CDC's workforce, shuttering vital health programs, and hamstringing others. Earlier this month, a gunman, warped by vaccine misinformation, opened fire on the CDC's campus, riddling its buildings with hundreds of bullets, killing a local police officer, and traumatizing agency staff.

Microsoft has introduced AI models that it trained internally and says it will begin using them in some products. This announcement may represent an effort to move away from dependence on OpenAI, despite Microsoft's substantial investment in that company. It comes more than a year after insider reports revealed that Microsoft was beginning work on its own foundational models.
A post on the Microsoft AI blog describes two models. MAI-Voice-1 is a natural speech-generation model meant to deliver "high-fidelity, expressive audio across both single and multi-speaker scenarios." The idea is that voice will be one of the main ways users interact with AI tools in the future, though we haven't really seen that come to fruition so far.
The second model is called MAI-1-preview, and it's a foundational large language model specifically trained to drive Copilot, Microsoft's AI chatbot tool. It was trained on around 15,000 Nvidia H100 GPUs, and runs inference on a single GPU. As reported last year, this model is significantly larger than the models seen in Microsoft's earlier experiments, which focused on smaller models meant to run locally, like Phi-3.

Microsoft's fifth major iteration of Windows 11 is nearing its release to the general public—the Windows Insider team announced today that Windows 11 25H2 was being put into its Release Preview Channel, the final stop for most updates before they become available to everyone. That's around two months after the first Windows builds with the 25H2 label were released to the other preview channels.
Putting a new yearly Windows update in the Release Preview channel is analogous to the "release to manufacturing" (RTM) phase of years past, back when updates shipped on physical media that needed to be manufactured. Build numbers for this version of Windows start with 26200, rather than 24H2's 26100.
The 25H2 update doesn't do a lot in and of itself, other than reset the clock for Microsoft's security updates (each yearly release gets two years of security patches). Microsoft says that last year's 24H2 update and this year's 25H2 update "use a shared servicing branch," which mostly means that there aren't big under-the-hood differences between the two. Installing the 25H2 update on a PC may enable some features on your 24H2 PC that had already been installed but had been disabled by default.
