• Ghost particles slip through Earth and spark a hidden atomic reaction
  Scientists have managed to observe solar neutrinos carrying out a rare atomic transformation deep underground, converting carbon-13 into nitrogen-13 inside the SNO+ detector. By tracking two faint flashes of light separated by several minutes, researchers confirmed one of the lowest-energy neutrino interactions ever detected.
• Paper mill waste could unlock cheaper clean energy
  Scientists developed a high-performance hydrogen-production catalyst using lignin, a common waste product from paper and biorefinery processes. The nickel–iron oxide nanoparticles embedded in carbon fibers deliver fast kinetics, long-term durability, and low overpotential. Microscopy and modeling show that a tailored nanoscale interface drives the catalyst’s strong activity. The discovery points toward more sustainable and industrially scalable clean-energy materials.
