Small airplane, for article on sustainable aviation fuel

Gulfstream completes first-ever transatlantic flight with 100% Sustainable Aviation Fuel

Sustainable aviation fuel just crossed the Atlantic on its own, with no fossil jet fuel in the tank. A Gulfstream G600 flew from Savannah, Georgia to Farnborough, England in under seven hours, becoming the first aircraft to make the transatlantic journey on 100% SAF. The engines weren’t modified for the trip, hinting that existing planes could one day run on cleaner fuel without expensive retrofits. Gulfstream now plans to share the flight data with U.S. regulators to help certify full SAF use beyond today’s blended limits. For an industry where battery and hydrogen flight remain distant, this single crossing offers something rare: a glimpse of long-haul aviation that could actually clean up before 2050.

New Jersey to ban sales of gas-powered cars by 2035

Under the state Department of Environmental Protection’s “Advanced Clean Cars II” rule, manufacturers must ensure that 43% of new light-duty vehicles they make in 2027 are electric, with the percentage rising annually to 100% by 2035. Most consumer cars and pickup trucks are considered light-duty.

For the first time, U.S. prisoners graduate from top university

Prison education just crossed a remarkable threshold: sixteen men at Stateville Correctional Center in Illinois became the first incarcerated students in the U.S. to earn bachelor’s degrees from a top-ten ranked university. Northwestern’s program now enrolls around 100 students across two facilities, including a women’s prison, with graduates already planning law school and youth-focused nonprofits. One graduate’s mother, who hadn’t seen her son in nearly two decades, watched him walk across the stage in cap and gown. With Pell Grants finally restored to incarcerated students after a nearly thirty-year ban, this ceremony hints at what’s possible when elite institutions treat people behind bars as full participants in higher learning — a shift that could ripple through prisons and universities alike.

Heirloom Carbon Technologies opens first carbon capture facility in the U.S.

Direct air capture has gone commercial in the United States for the first time, with Heirloom Carbon Technologies opening a plant in Tracy, California that can pull 1,000 metric tons of CO2 straight from the sky each year. The company speeds up a natural process: heating limestone, then letting the mineral soak up atmospheric carbon on open-air trays in days rather than years. The captured CO2 is locked into concrete and stored underground, with companies like Microsoft and Shopify buying removal credits to fund operations. Heirloom went from capturing one kilogram to one million kilograms in just over two years, and hopes to keep copying the design. Tackling legacy emissions, not just new ones, may be essential to stabilizing the climate worldwide.

Human eye, for article on whole-eye transplant

New York surgeons perform world’s first successful eyeball transplant

Whole-eye transplant surgery has been performed successfully for the first time, with a team at NYU Langone Health spending more than 20 hours combining a donor eyeball, a partial face transplant, and a stem cell infusion into the optic nerve. The patient, Aaron James, lost much of his face in a 2021 electrical accident, and surgeons had carefully preserved his optic nerve in anticipation of exactly this kind of operation. Doctors say the transplanted eye is healthy and blood is flowing to the retina, though James has not regained sight. Restoring vision may still be years away, but this opens a real door for people with catastrophic eye injuries — proof that something once considered impossible is now a starting point.

Offshore wind farm, for article on offshore wind capacity

Biden-Harris administration approves largest offshore wind project in U.S. history

Coastal Virginia Offshore Wind, approved by federal regulators in 2023, could power more than 900,000 homes once its 176 turbines start spinning about 23.5 nautical miles off Virginia Beach. By late October that year, the first eight monopile foundations had already arrived at the Portsmouth Marine Terminal — a tangible sign the project had moved from paperwork into steel. Dominion Energy also committed to fishery mitigation funds and vessel speed limits to protect whales, sea turtles, and Atlantic sturgeon during construction. Alongside four other approved projects, CVOW is helping seed an offshore wind industry that barely existed in American waters a decade ago, with Hampton Roads positioning itself as a lasting hub for the clean-energy supply chain.
