  • Global fossil fuel emissions set to fall in 2026, but total CO2 keeps rising
    Global fossil fuel emissions are projected to fall in 2026 as renewable energy and electric vehicles gain ground, but rising emissions from deforestation threaten to push total CO2 emissions to a new record. Scientists warn that the world's remaining carbon budget for limiting warming to 1.5°C could be exhausted in less than four years, even […]
  • A hidden limit of space and time could unlock electronics 100,000 times faster
    Scientists have discovered a surprising quantum limit that prevents electrons from being tracked with unlimited precision in both space and time. The breakthrough could pave the way for manipulating chemical reactions and developing electronics hundreds of thousands of times faster than today's technology.
  • Scientists discover that a clogged filter could revolutionize oil refining
    Scientists have developed a remarkable new membrane that separates crude oil at room temperature, using the oil itself to create microscopic filtration channels. The breakthrough could cut refining energy consumption by nearly 32%, carbon emissions by almost 38%, and operating costs by 36%, potentially transforming one of the world's most energy-intensive industries.
  • SLAC scientists find conclusive proof of a mysterious third type of magnetism
    For nearly 90 years, scientists believed magnetism fell into just two categories, but researchers have now confirmed a remarkable third type called altermagnetism. Using specialized X-rays, they uncovered a unique magnetic signature that proves these materials behave differently from conventional magnets. Altermagnets combine stability with the ability to efficiently carry information, potentially overcoming major limitations […]
