New twice-yearly shot to prevent HIV achieves 100% success rate in late-stage trial

Lenacapavir, a twice-yearly HIV prevention shot, protected every single one of 2,134 women who received it in a late-stage trial across South Africa and Uganda — a 100% efficacy result so striking that monitors ended the blinded phase early. The breakthrough matters because daily prevention pills, while powerful in theory, often falter in real life: stigma, forgotten doses, and disrupted routines all chip away at protection. Two clinic visits a year, by contrast, means a full year of coverage. The remaining hurdle is access, with advocates pressing manufacturer Gilead to license generic versions for the regions hardest hit. If that happens, a tool this effective could reshape the global push to end the HIV epidemic by 2030.

Sierra Leone bans child marriage

Sierra Leone just made child marriage a serious crime, with anyone arranging the marriage of a girl under 18 now facing at least 15 years in prison. President Julius Maada Bio signed the Prohibition of Child Marriage Act in Freetown alongside First Lady Fatima Bio, who led the six-year campaign that made it happen. Her fight is personal — she nearly became a child bride herself. The law reaches grooms, parents, and even wedding guests, and it lands in a country where the Ministry of Health estimates one in three girls is married before 18. For a movement working to keep girls in school and alive through childbirth, this is the kind of legal backbone that changes what’s possible.

Wind turbines amid clouds, for article on E.U. wind power, for article on renewable electricity generation

Seven countries now generate 100% of their electricity from renewable energy

Renewable energy now powers more than 99.7% of electricity in seven countries: Albania, Bhutan, Nepal, Paraguay, Iceland, Ethiopia, and the Democratic Republic of Congo. Each one leaned into what their landscape offered — Himalayan rivers, volcanic heat, massive shared dams — and built their grids around it. They’re the leading edge of a wider shift, with roughly 40 countries now sourcing at least half their electricity from renewables. Stanford’s Mark Jacobson puts it plainly: no miracle technologies are needed, just focused deployment of wind, water, and solar. These seven nations are quiet proof that a modern society running on clean power isn’t a distant goal — it’s already happening, and the rest of the world is catching up.

New types of mosquito bed nets could cut malaria risk by up to half, trial finds

New mosquito bed nets cut malaria transmission by 20 to 50 percent in a major trial across 17 African countries, offering a real answer to the growing problem of insecticide resistance. The nets pair the standard pyrethroid coating with a second insecticide that hits mosquitoes through a different biological pathway, so the ones that used to shrug off treated nets no longer can. At under three dollars each, they cost about the same as the older versions they’re replacing. Paired with the malaria vaccine now rolling out across Africa, these nets are part of a layered defense that could meaningfully shift the trajectory of a disease that still kills hundreds of thousands of people every year.

Young trees, for article on African reforestation

The TREES program has planted tens of millions of trees across Africa since 2015

Reforestation done right looks less like a planting day and more like a four-year partnership with farmers — and the TREES program has quietly restored more than 41,000 hectares across nine African countries, an area roughly seven times the size of Manhattan. Instead of dropping seeds on remote land, TREES helps smallholder families build “forest gardens” of about 5,800 trees per hectare, weaving in fruit orchards, food crops, and windbreaks that feed households and generate a market surplus. In Kenya’s Kesouma region alone, 17,000 farmers have joined in. Earlier this year, the UN named it a World Restoration Flagship — a reminder that the most durable climate work tends to be the kind that pays the people doing it.

‘Historic milestone’ as global child mortality hits record low of 4.9 million in 2022

Child deaths worldwide have fallen to 4.9 million in 2022 — the lowest number ever recorded, and roughly half the toll of the year 2000. Behind that drop is decades of unglamorous, working-everyday care: vaccines, bed nets, oral rehydration, skilled midwives, and community health workers showing up in their own neighborhoods. Rwanda offers a remarkable glimpse of what’s possible, having cut its under-five mortality rate by more than 80% since the aftermath of the 1994 genocide through community-based insurance and a serious investment in primary care. The number is still far too high, and newborns and children in conflict zones remain especially vulnerable. But the trend is one of humanity’s quiet, steady triumphs — proof that coordinated care, sustained over decades, saves millions of lives.

Zambia passes landmark law amendment ending child marriage

Zambia’s new child marriage ban closes a loophole that left girls in customary marriages with no minimum age protection at all. Before the 2023 reform, nearly one in three Zambian women aged 20-24 had married before turning 18. The amendment voids any marriage involving someone under 18, treating civil and traditional unions equally — a change advocates fought for over many years. It joins Zambia with a growing group of African nations drawing a clear line at 18 for both girls and boys. Laws alone won’t end the practice, but they create the foundation everything else is built on: a national commitment, a basis for protection, and a signal to girls that their futures belong to them.

Ethiopia becomes first country to ban combustion-powered vehicles

Ethiopia just became the first country anywhere to ban the import of gasoline and diesel cars, with the policy announced in late January 2025. What makes this remarkable is the foundation underneath it: every kilowatt powering an Ethiopian EV comes from renewable sources, mostly hydropower, so these vehicles are genuinely zero-emission from the moment they plug in. The shift is also deeply practical — Ethiopia has been spending around $6 billion a year on oil imports, with most of that fueling vehicles, money that can now flow into homegrown clean transport instead. Wealthier nations have led on EV adoption, but none have drawn this line. Ethiopia just showed the rest of the world a bolder version of what’s possible.

Cameroon launches the world’s first routine malaria vaccine program

Malaria vaccine rollout reached a historic milestone in January 2024 when Cameroon became the first country to administer the RTS,S vaccine, also known as Mosquirix, as part of a routine national immunization program. More than 662,000 doses began reaching children across the country, targeting a disease responsible for 95% of global malaria deaths, most among children under five. The moment caps over 35 years of development and a successful WHO recommendation in 2021. With 19 additional African countries planning to follow, the rollout could eventually protect millions of children each year.
