New tuberculosis vaccines could save 7.3 million lives by 2050, Gavi analysis finds
Gavi, the Vaccine Alliance, reported on September 14, 2026, that a new generation of tuberculosis vaccines now in the pipeline could save an estimated 7.3 million lives between 2030 and 2050 while unlocking roughly $135 billion in economic benefits across low- and middle-income countries. Seven candidate vaccines targeting adolescents and adults, spanning adjuvanted protein, live-attenuated and mRNA platforms, are now in Phase 1, 2 and 3 trials and could reach the public from 2029 -- the first meaningful advance since the century-old BCG vaccine, whose protection wanes in adulthood. TB remains the world's deadliest infectious disease, having caused 10.7 million cases and 1.2 million deaths in 2024, and Gavi is calling for early planning to ensure equitable access once the new vaccines are approved.

Chinook salmon reclaim 88% of historic range within two years of world's largest dam removal
A peer-reviewed study published in Scientific Reports and highlighted this week confirmed that Chinook salmon have reoccupied 88% of their historical habitat on the Klamath River within just two migratory seasons of the last of four dams being breached in August 2024, the largest dam-removal project in history. More than 20,000 Chinook have pushed upriver in the two years since, alongside returning coho salmon, steelhead and Pacific lamprey, while researchers say the river's restored natural flows have also improved water quality. The rapid recolonization is seen as strong evidence for the ecological payoff of dam removal, even as the Yurok Tribe and conservation groups continue pressing regulators over reduced flows during this year's low-snowpack drought.

India installs record 27 gigawatts of solar power in first half of 2026, up 50% year-on-year
India added a record 27 gigawatts of solar capacity in the first half of 2026, a 50% jump from the 18 gigawatts installed in the same period of 2025, pushing the country's cumulative installed solar capacity past 165 gigawatts by June, according to figures reported this week. The surge reflects falling panel costs, streamlined project approvals and continued state-level incentives, and positions India as one of the fastest-growing solar markets in the world as it works toward its target of 500 gigawatts of non-fossil-fuel generation capacity by 2030.

Scientists decode ultrafast 'fishnet' contraction that could inspire faster artificial muscles
Researchers reported this week, in findings published in the Proceedings of the National Academy of Sciences, that the single-celled organism Spirostomum ambiguum can shrink to one-quarter of its body length in under 5 milliseconds -- hundreds of times faster than a human blink -- using a calcium-powered protein network arranged like a fishnet across the cell's exterior. The fishnet is built from fibrous structures called myonemes, made of the calcium-binding proteins centrin and Sfi1, which lose their stiffness and clump together in the presence of calcium ions, yanking the net tight and contracting the cell almost instantaneously. Scientists say the mechanism, among the fastest known in biology, could inspire a new generation of artificial muscles and synthetic cellular machinery capable of moving far faster than today's designs.

Newer blood thinners linked to slower cognitive decline in Alzheimer's patients with irregular heartbeat
Researchers at Sweden's Karolinska Institutet reported September 17, 2026, in the European Heart Journal, that newer NOAC blood thinners were associated with slower cognitive decline in patients who have both atrial fibrillation and Alzheimer's disease. Analyzing data from 7,308 patients with both conditions, the team found NOAC treatment was linked to a slower drop in Mini-Mental State Examination scores as well as lower risks of death, stroke and blood clots compared with no anticoagulant use, while older warfarin treatment lowered those same risks but carried a higher bleeding risk. The modest year-on-year benefit could compound meaningfully over time, researchers said, offering a promising, low-cost angle for protecting cognition in a fast-growing patient population, though as an observational study it cannot yet prove cause and effect.
