Columbia and UC Berkeley researchers report in Nature that microplastics spontaneously generate reactive oxygen species in the water around them. The finding offers a chemical route to the tissue damage associated with microplastics, though the authors hedge on harm to people.

Columbia researchers report DRT10, a bacterial antiviral system whose reverse transcriptase writes repeat DNA by a route that parallels human telomerase. The Nature abstract reports bacterial biochemistry, structures and phylogenetics, and Sternberg calls the editing and telomere-repair uses early days.

Nobel winner Woodford points to forward guidance, the practice Fed Chair Warsh scrapped
Michael Woodford, 71, a joint Nobel economics winner, named forward guidance first as his research in use, a practice Fed Chair Kevin Warsh scrapped. The Fed is now scaling back advance signaling on its rate path, en.sedaily.com reported, so markets have less to read.

Existing immunity appears to hold against severe illness as antibody-dodging XFG dominates covid
XFG, the covid lineage behind about 60 per cent of sequenced cases worldwide, escapes antibodies better than earlier variants in lab tests. No rise in severity has been reported so far, and immunity from past infections and vaccines appears to protect most people from serious illness.

New York Fed economists estimate Trump's tariffs had raised US consumer goods prices 2.9 points by February 2026. The inflation effect has since peaked, but the higher price level persists and the researchers expect the tariff impact to carry into next year.

Aerosol pollution in 46 cities rose about a third after U.S. embassies stopped publishing air readings
Columbia researchers found aerosol pollution rose about 33% across 46 cities after U.S. embassies stopped publishing air-quality readings in 2025. The result is evidence that public monitoring data helps hold pollution down, though the published summary does not say whose behavior changed.

Columbia-led team is engineering glowing yeast into a handheld PFAS test for water utilities
Virginia Cornish's Columbia team is building a yeast-and-chip sensor for PFAS, the chemicals found in nearly half of US municipal water supplies. Utilities would get a handheld, real-time reading, though the yeast meant to detect PFOA and PFOS are still being engineered.

Brookings paper warns financing for a $10.3 trillion AI buildout is moving off balance sheets
Stijn Van Nieuwerburgh's Brookings paper projects $10.3 trillion in US AI investment through 2032, 3.63% of GDP a year against the railroads' 2.24%. It warns that more of the money is moving into off-balance-sheet vehicles that can hide correlated exposures before a downturn.

Dated livestock bones tie Madagascar's megafauna losses to herds that spread 1,200 years ago
Oregon State and Columbia researchers found livestock spread across Madagascar about 1,200 years ago, as its large native herbivores declined. People may have arrived millennia earlier, so the timing argues against hunting alone as the cause of the extinctions.

A Columbia estimate puts $800 billion of bank credit behind the AI buildout
Stijn Van Nieuwerburgh's $800 billion adds up mortgages, syndicated loans and project debt across AI's physical infrastructure, and he says loans going bad there would cut what banks can lend everyone else.

A layered magnet converted microwaves to light across a 300 MHz window without a resonator
Physicists at the City College of New York drove magnons in CrSBr with microwaves and read the signal out on reflected laser light, a conversion mechanism that still needs large efficiency gains before it can move quantum states.

Richer countries get more accurate weather forecasts, 35 years of ECMWF data show
Two researchers scored 35 years of ECMWF forecasts against the observed weather and found accuracy rises with national income at every lead time out to a week. The reasons are mostly geographic and only partly a matter of spending.

Stacking 12 JWST transits pushes an exomoon search down to 0.1 Earth radii
David Kipping's preprint reports no moon larger than a tenth of Earth's radius around the temperate rocky planet LP 890-9 c. The point of the exercise is that averaging repeat visits removes the detector noise astronomers had treated as a hard floor.

Two Physical Review Letters studies read published LIGO data with different methods and both picked out binaries whose larger member spins fast and sits tilted. One of the estimates puts that group near 14 percent of pairs.
