    In current stretchable electronic devices, connection points between modules are made using commercially available pastes and break easily under mechanical deformation. An innovative connection interface has been developed to enable robust stretchable devices to be reliably assembled in a Lego‑like manner by simply pressing the interfaces of two modules together without pastes.

    The electrolytic splitting of saline water is a highly desirable and sustainable method for the mass production of green hydrogen, but seawater contains many impurities that hinder the long-term stability of conventional electrolysis systems. A method for enabling the electrolysis of seawater has been developed that addresses previous side-reaction and corrosion problems.

    Frequency-comb lasers are measuring sticks of the optical world and are used in metrology and sensing applications owing to their rigid, comb-like light spectra and metronomic pulsed output. A frequency comb with time-programmable pulses breaks this rigid mould and, in a demonstration of its utility, measures distances at the quantum limit of precision.
