A repurposed imine reductase uses photoexcited NADP+ to generate P-centred radicals and forge chiral carbon–phosphorus bonds with divergent stereocontrol. Chemists have long struggled to control the handedness of phosphorus-centred radicals, reactive intermediates that could unlock a valuable class of molecules but have stubbornly resisted stereocontrol Now a team writing in…
Are you sure you want to import this news into ? Secondary serotonin aptamer (green) binds to the target-bound primary serotonin aptamer (pink). 2026 EPFL CHEMINA CC BY SA EPFL scientists have reimagined how aptamers – short DNA strands used in molecular sensors – detect their targets. Their versatile sensing…
Researchers at the National Graphene Institute (NGI) at The University of Manchester have been awarded a £1.2 million (about US$1.6 million) Engineering and Physical Sciences Research Council (EPSRC) Standard Research Grant to…
Acoustic excitation provides a physical means of interrogating and modifying biological structures, yet the relationship between resonance, energy absorption and irreversible damage remains incompletely established. This…
Repetitive DNA, defined as sequence motifs that recur throughout the genome, comprises about 54% of the human genome. Large amounts of repetitive DNA were long labeled “junk” or “selfish” DNA, yet growing evidence shows that…
Newswise — A Korean research team has developed a transfer printing process that enables solid electrolytes, a key component of solid-state batteries, to be fabricated as very thin, uniform, and defect-free layers over large areas. The technology is expected to provide a foundation for the large-area manufacturing of high-energy-density solid-state…
Ammonia is essential for global agriculture, but its production via the Haber-Bosch process is energy-intensive and emits vast amounts of CO₂. Electrocatalytic nitrogen reduction offers a greener alternative, yet breaking nitrogen’s stubborn triple bond under mild conditions has remained a major hurdle. Now, researchers have introduced a conceptually novel mechanism—hydroxide-activated…
New antiperovskite-supported cobalt catalyst can produce ammonia from nitrogen and hydrogen under mild conditions without precious metals, as reported by researchers from Science Tokyo. This self-organizing nanostructured…
Hydrogen could help industries reduce their dependence on fossil fuels, but its environmental benefits depend largely on how it is produced. Conventional hydrogen production can release substantial amounts of greenhouse gases…
