The brains of people under general anaesthesia continue to process words and sounds, a study finds.Credit: BSIP/UIG Via Getty People given general anaesthesia fall into a coma-like state in which their memory and perception of pain are switched off. But new data reveal that the hippocampus — a deep brain structure crucial for memory —…

Mouse lines All experiments were conducted in compliance with the Association for Assessment of Laboratory Animal Care policies and approved by the Institutional Animal Care and Use Committees of the University of Virginia, University of Washington and University of California, Irvine. Mice were housed on a 12-h:12-h light–dark (LD) cycle with food (PicoLab Rodent Diet…

Cryogenic QTM All measurements in this work were performed in a cryogenic QTM system operating at a temperature of 4 K, as described previously45. For conductance measurement, voltage biases are applied using a custom-built digital-to-analogue converter array, capable of supplying both d.c. and a.c. signals with 1 μV resolution. Currents were measured using a FEMTO current amplifier,…

RESEARCH BRIEFINGS 06 May 2026 By precisely shaping the leading edge of ultrafast high-power laser pulses, bright ‘harmonic’ radiation has been generated with great efficiency from plasma oscillating at almost the speed of light. This long-sought regime removes a key barrier to the production of extremely intense electromagnetic fields for applications such as compact particle…

From the moment of its discovery, the antagonistic relation between superconductivity and a magnetic field has provided a complex playground for experimentalists and theorists alike. The measurement of the critical field and the Meissner effect12 have anchored phase-transition theories13,14, and the trapping of quantized flux inside superconductors has provided direct evidence for the existence of…

Mouse husbandry All experiments were approved and conducted in accordance with the Cold Spring Harbor Laboratory Institutional Animal Care and Use Committee. All animals used were adult (>3 months) male and female mice. Laboratory mice were acquired from The Jackson Laboratory (C57BL/6J). Colonies of laboratory and singing mice were maintained at 20–22 °C, 30–70% humidity and a…
