Research could pave the way for more resilient winter cereals in warmer climates
June 3, 2026 dialog Research could pave the way for more resilient winter cereals in warmer climates Lisa Lock Scientific Editor Robert Egan Associate Editor The arrival of winter marks not only a change in weather, temperature, and day length, but also a change in our activity and behavior. The social outdoor events and trips to the beach over summer soon become a distant memory, and we ready ourselves for more solitary evenings indoors with a hot drink and a good book. The same can be said...
Warming boosts natural methane emissions as microbes fail to keep pace
Warming boosts natural methane emissions as microbes fail to keep pace Sadie Harley Scientific Editor Robert Egan Associate Editor A new study led by Professor Mark Trimmer of Queen Mary University of London, published in the journal Nature Climate Change, explains how increases in natural methane emissions will be maximized under future climate warming. Say "methane" and most people think of cows, yet nearly half of all methane is produced by microbes in the natural world, especially lakes,...
How high-end credit card perks are hurting shoppers who pay in cash
This article is part of “Unaffordable America,” a series examining rising economic inequality in the U.S. and the policies that drive it. RUCKERSVILLE, Va. — At the Tiger Fuel gas station and convenience store near the foothills of the Blue Ridge Mountains, the managers expect to pay more in fees to credit card companies this year than they will on rent — one more expense weighing on the company and its customers amid the surging price of gas. Those credit card fees — which can be as high as...

Dogs uncover invasive pests that experts missed in real-world vineyard tests Sadie Harley Scientific Editor Robert Egan Associate Editor At a Maryland vineyard, Debi Persing guided her Boston terrier, Xephyr, slowly down a row of grapevines. Vineyard workers and scientists had already identified several invasive spotted lanternfly egg masses hidden among the vines. They believed they had found them all.
Endangered basking sharks rely on the ocean twilight zone during long-distance migrations
Endangered basking sharks rely on the ocean twilight zone during long-distance migrations Lisa Lock Scientific Editor Robert Egan Associate Editor Endangered basking sharks aren't fasting during long-distance migrations. A new study led by the Woods Hole Oceanographic Institution shows that they may be foraging along the way, and in much deeper areas of the ocean than previously thought. As filter feeders, this species is most often observed close to the surface, especially in waters off of...

The massive circular burial cave carved into rock is Europe's largest Copper Age mass burial, containing over 1,300 individuals,...
Plants boost carbon uptake through water efficiency, not heat adaptation, global analysis reveals
Plants boost carbon uptake through water efficiency, not heat adaptation, global analysis reveals Gaby Clark Scientific Editor Robert Egan Associate Editor An international team of scientists has discovered that plants are not responding to global warming in the way researchers long assumed. Scientists have expected that ecosystems would keep pace with warming by rising the temperature at which photosynthesis works best. A new study published in One Earth is challenging that theory.
