Worth Noting

A single CAR-T-style infusion held HIV suppressed in a small group of patients for years, suggesting immunotherapy could one day replace daily antiretrovirals.

A Single Infusion Could Suppress H.I.V. for Years, Study Suggests

The approach borrows from blood-cancer treatment and, if it scales, would be the most significant shift in HIV management since combination therapy arrived in the 1990s.

Geologic hydrogen — naturally occurring H₂ seeping from the earth’s crust — has drawn a wave of start-ups and fresh venture capital, with drillers now going after it directly.

The Quest for an Elusive Clean Fuel Is Moving Underground

Unlike green hydrogen made by electrolysis, natural geological hydrogen would require no energy input to produce, potentially making it the cheapest low-carbon fuel yet discovered — if the underground deposits prove large and accessible enough.

Fervo Energy, the geothermal start-up that adapted oil-and-gas fracking techniques to tap the earth’s heat, raised $1.9 billion in its IPO — a rare clean-energy market debut in a hostile policy environment.

A Start-Up Aiming to Make Geothermal Energy Mainstream Goes Public

The listing signals that investors see enhanced geothermal as a credible baseload power source, not merely a niche technology, at a moment when AI data-center demand is straining grids.

Coal-burning power plants released more mercury into the air last year than in any recent year, reversing a decade-long decline, according to a Times analysis.

As Coal Rebounds, More Toxic Mercury Is in the Air

Mercury is a potent neurotoxin that impairs fetal brain development, and the reversal is a direct consequence of the administration’s directive to keep aging coal plants operating past their scheduled closure dates.

Scientists bored three thousand feet into the Thwaites Glacier in Antarctica over eight weeks to place sensors directly in the meltwater cavity — the first direct measurements of the ice-ocean interface at the world’s most consequential glacier.

The Hole in the Ice at the End of the Earth

Thwaites alone holds enough ice to raise global sea levels by several feet; understanding how warm ocean water is eating at its base from underneath is the critical unknown in sea-level projections.

Lithuania is restoring peat bogs along its border with the dual purpose of sequestering carbon and creating terrain that tanks cannot cross.

They’ve Got a Plan to Combat Global Warming (and Also Russian Tanks)

The project is a rare case where climate restoration and national security interests are genuinely aligned rather than in tension, and it could serve as a model for other NATO frontier states.

One Thing Worth Reading Deeply

The Astounding Discovery That Could Link Eastern and Western Medicine

A long-form magazine piece on the interstitium — a fluid-filled network of connective tissue now being recognized as a distinct organ system, effectively a second circulatory architecture woven through the body. The piece is worth reading in full because it sits at the intersection of frontier anatomy, cancer biology (the interstitium may be a highway for metastasis), and the contested science of acupuncture, asking whether a discovery made with modern imaging might vindicate one of medicine’s oldest puzzles. The writing is careful not to overclaim while still conveying how genuinely unsettling it is to find a major anatomical structure that textbooks missed entirely.
