June 9 Yale Prison Education Initiative just celebrated its first-ever commencement, with seven students receiving associate degrees inside a Connecticut prison in June 2023. Four of them had been taking classes since the program's very first cohort in 2018, when only 12 students were enrolled — meaning these graduates literally helped build the program they were graduating from. The ceremony at MacDougall-Walker Correctional Institution included caps, gowns, families, and Governor Ned Lamont, who responded to each...

June 6 The amendment follows similar rulings in Denmark and Spain, where the law was recently changed to define rape as sexual assault without explicit consent.

June 6 With this expansion, all California children under 5 will be eligible to receive a free book in the mail every month, as the program scales over the next several years.

June 5 Space-based solar power just crossed from theory into reality: a Caltech team has, for the first time, beamed energy from orbit down to a receiver on Earth. The signal arrived at a rooftop in Pasadena exactly when, where, and at the frequency engineers predicted — proof that the precision needed for a future full-scale array is achievable. The demonstrator weighed just 50 kilograms and used flexible, lightweight arrays never before flown for this purpose....

June 5 Chaco Canyon's ancestral landscape — home to more than 4,700 known archaeological sites outside the park's boundaries alone — now has meaningful federal protection after decades of Indigenous advocacy. The 20-year withdrawal shields this sacred desert region from new oil, gas, and mining claims, finally aligning national policy with what Pueblo and Tribal Nations have long called necessary. Existing leases remain valid, though, meaning some drilling activity continues — a reminder that this is...

June 4 The ruling adds pressure on the Japanese parliament to legalize same-sex marriages. Japan remains the only country in the G7 that has not legalized marriage equality.

June 4 Multiple sclerosis affects nearly 3 million people worldwide, and until now no treatment has been able to reverse damage already done — only slow what comes next. A Johns Hopkins team may have changed that calculus, using a microparticle therapy that floods the immune system with protective T cells while reducing the rogue cells attacking myelin. Researchers are clear, however, that many such therapies succeed in rodents only to fail in humans, and trials...

June 2 The Serum Institute of India and Path successfully tested an effective and affordable vaccine for meningitis, a disease that claims the lives of an estimated 250,000 people each year.

June 1 PFAS are used in nonstick cookware, stain-resistant fabrics, and firefighting foams, and have been linked with higher cholesterol, lower fertility, developmental delays in children, and a greater risk of cancer.

June 1 New Zealand is putting $140 million toward swapping out the coal furnaces at its largest steel plant — a single project that will shrink the country's total emissions by a full 1%. The Glenbrook plant currently burns coal to turn iron-rich sands into steel, but a new electric arc furnace will melt recycled scrap instead, drawing power from a grid already running on roughly 80% renewables. By 2027, the switch is expected to cut...
