— In the first three months of 2025, renewables generated more than a quarter of all electricity in the United States, reports Green Energy Times, citing data from the Energy Information Administration.

This means the mix of renewables has strengthened its position as the second largest source of electrical generation, behind only natural gas, with the gap closing rapidly, says Green Energy Times.

— Stanford University researchers have developed a new technique called the milli-spinner thrombectomy that could significantly improve success rates in treating strokes, as well as heart attacks, pulmonary embolisms and other clot-related diseases. 

The milli-spinner is an extension of work on millirobots – tiny, origami-based robots built to swim through the body to dispense medicine or assist with diagnostics. The milli-spinner can shrink blood clots without rupturing them. The research is published in the journal Nature.

— MIT engineers have developed a new 3D printing method that generates less waste. The details are published in the journal Advanced Materials Technologies.
