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.
