Scientific attention scatters toward thresholds

Tandem perovskite solar cells reached 34% efficiency — ten percentage points above commercial silicon. Sodium-ion batteries emerge as lithium alternatives. A triplet superconductor may have been spotted — a material that could transmit both electricity and electron spin with zero resistance, potentially stabilising quantum computers. The first customised CRISPR treatment was given to a baby with a rare genetic disease. Researchers designed enzymes with functions evolution never created. An iron- ...
