摘要:Magnetic field generation on Earth has probably persisted for at least 3.5 Gyr (refs. 1,2), initially sustained by secular cooling of the Earth's core and, more recently, by the growth of the solid inner core3. Numerical models of the present-day geodynamo have proved to be successful in producing Earth-like magnetic fields4, 5, 6-7 and approaching realistic dynamic regimes8, 9, 10-11. However, thermal evolution12,13 and palaeomagnetic records14,15 suggest that the geodynamo operated for most ...

摘要:Brain-computer interfaces (BCIs) have the potential to restore communication for people who have lost the ability to speak owing to a neurological disease or injury. BCIs have been used to translate the neural correlates of attempted speech into text1, 2-3. However, text communication fails to capture the nuances of human speech, such as prosody and immediately hearing one's own voice. Here we demonstrate a brain-to-voice neuroprosthesis that instantaneously synthesizes voice with closed-loop ...

摘要:Cross-scale coupling from magnetohydrodynamics (MHD) to non-MHD scales is important in interpreting observations of explosive events in nature, such as solar flares and geomagnetic storms1,2. Experiments and observations also link it to the emergence of energetic particles and X-rays3. However, how this multi-scale physics affects the abrupt onset of reconnection remains unknown. Here we report observations from laboratory experiments involving two flux ropes with electron beams that induce ma...

摘要:The molecular hydrogen ions (MHI) are three-body systems suitable for advancing our knowledge in several domains: fundamental constants, tests of quantum physics, search for new interparticle forces, tests of the weak equivalence principle(1) and, once the anti-molecule (p) over bar(p) over bare(+) becomes available, new tests of charge-parity-time-reversal invariance and local position invariance(1-3). To achieve these goals, high-accuracy laser spectroscopy of several isotopologues, in parti...

摘要:Bdellovibrio bacteriovorus is a predatory bacterium that non-selectively preys on Gram-negative bacteria by invading the prey-cell periplasm, leaching host nutrients and ultimately lysing the infected cell to exit and find a new host1,2. The predatory life cycle of B. bacteriovorus is, in many ways, comparable to a bacteriophage. However, unlike phage defence, defence against B. bacteriovorus has not been widely investigated. Here we screened a collection of diverse Escherichia coli strains fo...
