This archive spans the years 2017 through 2025, a period marked by rapid advances in clean energy, medicine, technology, and social equity. It collects documented breakthroughs, policy wins, and scientific achievements from the present era. If you want evidence that progress is real and ongoing, this is where to look.
“For the first time, it is possible for water, produced by sunlight, to be even cheaper than tap water,” said Lenan Zhang, a research scientist from the team from MIT and Shanghai Jiao Tong University. “This opens up the possibility for solar desalination to address real-world problems.”
Ruter, the public transportation operator for Oslo, announced this week that it expects to take delivery of 137 more electric buses before the end of December 2023. That will make its bus fleet almost 100% electric 4 years ahead of the company’s initial schedule.
Researchers at the University of North Carolina have developed an AI model that can predict in real-time whether or not cancerous tissue has been fully removed during breast cancer surgery. The model performed as well as, or better than, human doctors.
At schools where 25% of families participate in income-based public benefits, such as the Supplemental Nutritional Assistance Program, the U.S. federal government now will cover the cost of free meals for all enrolled students. Previously, the qualifying threshold was 40%.
A writ of kalikasan — a rare Philippine legal remedy reserved for environmental threats spanning multiple provinces — has halted nickel mining on the ancestral lands of the Pala’wan people in Brooke’s Point, Palawan. The August 2023 Supreme Court ruling protects Mount Mantalingahan, a 120,457-hectare sacred range and watershed for five municipalities, where roughly 80% of the mining concession sat inside the core protected zone. For the Pala’wan, who have refused consent since 2005, the decision arrived after years of being ignored by the agencies meant to protect them. Lawyers call it unprecedented, and believe it could open the courtroom door for other communities defending forests across Palawan and beyond.
A tooth regrowth drug has entered human clinical trials in Japan, offering a potential third option alongside dentures and implants. The treatment works by blocking USAG-1, a gene that acts as a natural brake on tooth development, freeing the body to grow new teeth on its own. Researchers confirmed the approach first in mice, then in ferrets, before moving to people, and a pediatric trial is planned for children with anodontia, a rare condition that leaves six or more teeth missing. Dr. Katsu Takahashi, who has chased this idea since 2005, hopes for regulatory approval by 2030. With oral disease affecting some 3.5 billion people worldwide, regrowing real teeth could reshape dental care far beyond Japan.
Ocean protection just took a huge leap forward: more than 76 countries and the European Union signed the High Seas Treaty on its very first day open for signatures at the U.N. General Assembly. The agreement creates the first-ever legal framework to establish protected areas across international waters, which cover two-thirds of the planet yet remain almost entirely unguarded. It also requires that benefits from marine genetic resources — think pharmaceuticals drawn from deep-sea life — be shared fairly with nations in the Global South. Once 60 countries ratify, the treaty takes effect, opening the door to meeting the global goal of protecting 30% of the oceans by 2030 and giving marine life a fighting chance.
The U.S. Climate Alliance is a bipartisan coalition of 25 governors securing America’s net-zero future. Members have agreed to collectively reach 20 million climate-friendly heat pump installations across the coalition by 2030, with the aim of ensuring at least 40% of benefits flow to disadvantaged communities.
Indigenous land rights just got a powerful boost in Brazil, where the Supreme Court struck down a doctrine that required native communities to prove they were physically living on their land the day the 1988 constitution was signed. Six of the court’s 11 justices voted to reject the rule, immediately restoring territory to the Xokleng people of Santa Catarina, whose ancestors were violently driven from their homes more than a century ago. Legal experts say the decision could reshape hundreds of pending land disputes nationwide. Outside the courthouse, Indigenous people from across Brazil wept and celebrated — a reminder that protecting ancestral lands isn’t just about justice for the past, but about who gets to safeguard the forests, ecosystems, and futures we all depend on.
This milestone follows Volvo’s previous announcement in 2022 to discontinue the development of new internal combustion engines. By selling its stake in Aurobay, the joint venture responsible for its remaining combustion engine assets, Volvo redirected its focus entirely towards electric powertrains.
