Walmart Begins Building Out Nationwide EV Charging Network Across America
Walmart, the world's largest retailer, will be adding spaces for electric vehicle charging to parking lots in 19 different states, reports MLive:
The move follows up on a plan announced in 2023 to build a network of charging stations at Walmart and Sam's Club stores throughout the U.S... "With a store or club located within 10 miles of approximately 90% of Americans, we are uniquely positioned to deliver a convenient charging option that will help make EV ownership possible whether people live in rural, suburban or urban areas," wrote Walmart Senior Vice President of Energy Transformation, Vishal Kapadia in 2023. Walmart plans to have the nationwide network operating by 2030.

When 20-Year-Old Bill Gates Fought the World's First Software Pirates
Long-time Slashdot reader destinyland writes: Just months after his 20th birthday, Bill Gates had already angered the programmer community," remembers this 50th-anniversary commemoration of Gates' Open Letter to Hobbyists. "As the first home computers began appearing in the 1970s, the world faced a question: Would its software be free?"
Gates railed in 1976 that "Most of you steal your software." Gates had coded the BASIC interpreter for Altair's first home computer with Paul Allen and Monte Davidoff — only to see it pirated by Steve Wozniak's friends at the Homebrew Computing Club. Expecting royalties, a none-too-happy Gates issued his letter in the club's newsletter (as well as Altair's own publication), complaining "I would appreciate letters from any one who wants to pay up."
But freedom-loving coders had other ideas. When Steve Wozniak and Steve Jobs released their Apple 1 home computer that summer, they stressed that "our philosophy is to provide software for our machines free or at minimal cost..." And early open-source hackers began writing their own free Tiny Basic interpreters to create a free alternative to the Gates/Micro-Soft code. This led to the first occurrence of the phrase "Copyleft" in October of 1976.
Open Source definition author Bruce Perens shares his thoughts today. "When I left Pixar in 2000, I stopped in Steve Job's office — which for some reason was right across the hall from mine... " Perens remembered. "I asked Steve: 'You still don't believe in this Linux stuff, do you...?'" And Perens remembers how that movement finally won over Steve Jobs and carried the day. "Three years later, Steve stood onstage in front of a slide that said 'Open Source: We Think It's Great!' as he introduced the Safari browser, which at that time was based on the browser engine developed by the KDE Open Source project!"

Fourth US Wind Farm Project Blocked By Trump Allowed to Resume Construction
Vineyard Wind (powering Massachusetts) is one of five offshore wind projects "that the Trump administration tried to hold up in December," reports The Hill.
This week it became the fourth of those wind projects allowed by a judge to resume construction, the article notes, while even the fifth project "is still awaiting court proceedings."
Federal Judge Brian Murphy, a Biden appointee, issued a preliminary injunction blocking the administration's stop work order against Vineyard Wind... According to its website, when complete, Vineyard Wind would be able generate enough power for 400,000 homes and businesses. The project already has 44 operational wind turbines and was working on an additional 18. The Trump pause applied to the construction work that was not yet complete.

Scientists Create Programmable, Autonomous Robots Smaller Than a Grain of Salt
Researchers at the University of Pennsylvania and University of Michigan "have created the world's smallest fully programmable, autonomous robots," according to a recent announcement.
The announcement calls them "microscopic swimming machines that can independently sense and respond to their surroundings, operate for months and cost just a penny each."
Barely visible to the naked eye, each robot measures about 200 by 300 by 50 micrometers, smaller than a grain of salt. Operating at the scale of many biological microorganisms, the robots could advance medicine by monitoring the health of individual cells and manufacturing by helping construct microscale devices. Powered by light, the robots carry microscopic computers and can be programmed to move in complex patterns, sense local temperatures and adjust their paths accordingly... "We've made autonomous robots 10,000 times smaller," says Marc Miskin, Assistant Professor in Electrical and Systems Engineering at Penn Engineering and the papers' senior author. "That opens up an entirely new scale for programmable robots."
The announcement describes them as "the first truly autonomous, programmable robots at this scale" (as described in two recent academic articles). The team had to design a new propulsion system that utilized the unique locomotion physics in the microscopic realm, according to the university's announcement. So the robots "generate an electrical field that nudges ions in the surrounding solution."
Those ions, in turn, push on nearby water molecules, animating the water around the robot's body. "It's as if the robot is in a moving river," says Miskin, "but the robot is also causing the river to move." The robots can adjust the electrical field that causes the effect, allowing them to move in complex patterns and even travel in coordinated groups, much like a school of fish, at speeds of up to one body length per second...
To be truly autonomous, a robot needs a computer to make decisions, electronics to sense its surroundings and control its propulsion, and tiny solar panels to power everything, and all that needs to fit on a chip that is a fraction of a millimeter in size. This is where David Blaauw's team at the University of Michigan came into action... The robots are programmed by pulses of light that also power them. Each robot has a unique address that allows the researchers to load different programs on each robot. "This opens up a host of possibilities," adds Blaauw, "with each robot potentially performing a different role in a larger, joint task."

Microbes In Space Mutated and Developed a Remarkable Ability
"A box full of viruses and bacteria has completed its return trip to the International Space Station," reports ScienceAlert, "and the changes these 'bugs' experienced in their travels could help us Earthlings tackle drug-resistant infections..."
Scientists aboard the space station incubated different combinations of bacteria and phages for 25 days, while the research team led by biochemist Vatsan Raman carried out the same experiments in Madison, down here on Earth. "Space fundamentally changes how phages and bacteria interact: infection is slowed, and both organisms evolve along a different trajectory than they do on Earth," the researchers explain. In the weightlessness of space, bacteria acquired mutations in genes involved in the microbe's stress response and nutrient management. Their surface proteins also changed. After a slow start, the phages mutated in response, so they could continue binding to their victims.
The team found that certain space-specific phage mutations were especially effective at killing Earth-bound bacteria responsible for urinary tract infections (UTIs). More than 90 percent of the bacteria responsible for UTIs are antibiotic-resistant, making phage treatments a promising alternative.

99% of New US Energy Capacity Will Be Green in 2026
This year in America, renewables and battery storage "will account for 99.2% of net new capacity — and even higher if small-scale solar were included," reports Electrek, citing EIA data reviewed by the SUN DAY Campaign:
EIA's latest monthly "Electric Power Monthly" report (with data through November 30, 2025), once again confirms that solar is the fastest-growing among the major sources of US electricity... [U]tility-scale solar thermal and photovoltaic expanded by 34.5% while that from small-scale systems rose by 11.3% during the first 11 months of 2025 compared to the same period in 2024. The combination of utility-scale and small-scale solar increased by 28.1% and produced a bit under 9.0% (utility-scale: 6.74%; small-scale: 2.13%) of total US electrical generation for January to November, up from 7.1% a year earlier.
Wind turbines across the US produced 10.1% of US electricity in the first 11 months of 2025 — an increase of 1.2% compared to the same period in 2024. In November alone, wind-generated electricity was 2.0% greater than a year earlier... The mix of all renewables (wind, solar, hydropower, biomass, and geothermal) produced 8.7% more electricity in January-November than a year earlier and accounted for 25.7% of total US electricity production, up from 24.3% 12 months earlier. Renewables' share of electrical generation is now second to only that of natural gas, whose electrical output actually dropped by 3.7% during the first 11 months of 2025...
Since January 1 to November 30, roughly the beginning of the Trump administration, renewable energy capacity, including battery storage, small-scale solar, hydropower, geothermal, and biomass, ballooned by 45,198.1 MW, while all fossil fuels and nuclear power combined declined by 519.2 MW...
[In 2026] natural gas capacity will increase by only 3,960.7 MW, which will be almost completely offset by a decrease of 3,387.0 MW in coal capacity.
