China's 'Green Great Wall' tames desert growth, but scientists warn the fight is not over
For half a century, millions of workers have repeated a task across the deserts in northern China: inserting forearm-length sticks into shifting sand, first in a row, then in an intersecting line, gradually forming a grid. Then saplings are planted at the center of each small squ

Firefly brightness holds a cautionary tale about accepting older measurements
For over a century, the accepted value for a firefly's brightness has mostly stood, tracing its origins to experiments carried out in 1912. Through rigorous new analysis published in the American Journal of Physics, David Silver of Remiza AI in New York has discovered that this v

New imaging method reveals how electric fields reshape ferroelectric materials
New imaging method reveals how electric fields reshape ferroelectric materials
New research is shedding light on longstanding debates over the behavior of ferroelectric materials when those materials are exposed to electric fields. The findings stem from the use of a novel technique that allows researchers to observe the real-time behavior of domain walls i

Floating-electron catalyst withstands week in air while making ammonia under milder condit
A surface electrene, BaSiN2:O, developed by researchers at Science Tokyo enables efficient ammonia synthesis under mild conditions while overcoming the long-standing air instability of electrene materials. Synthesized by doping barium silicon nitride with oxygen, the material for

Space cargo costs could fall more than 90% by 2040, study suggests
The expense of launching cargo into space will plummet over the next few years, with the cost of reaching orbit forecast to more than halve between now and the end of the decade, and fall by around 93% by 2040, according to new Cambridge-led research.
Study reveals Hawaiian hotspot is getting hotter
Study reveals Hawaiian hotspot is getting hotter
Contrary to conventional geological thinking, the Hawaiian mantle plume has gotten hotter by about 250°C (480°F) over the past 47 million years. This discovery, led by Earth scientists at the University of Hawai'i at Mānoa, reverses the long-held idea that hotspots start out very
