Global burden of amphetamine, cannabis, cocaine and opioid use in 204 countries, 1990–2023: a Global Burden of Disease Study

Global Burden of Disease estimates show that between 1990 and 2023, the prevalence and burden of drug use disorders, inclusive of amphetamine, cannabis, cocaine and opioid use, have been increasing in high-income countries, particularly in the USA.

Microcantilever-integrated photonic circuits for broadband laser beam scanning

This work presents ultracompact and low-power laser beam scanners using microcantilevers embedded with nanophotonic circuits. These chip-scale devices are made in a semiconductor foundry and project visible light patterns in one or two dimensions.

Monolithically integrated, broadband, high-efficiency silicon nitride-on-silicon waveguide photodetectors in a visible-light integrated photonics platform

Efficient and broadband visible-light photodetectors will bring great advantages in applications such as biosensing and quantum information. Here the authors develop a photodetector with high quantum efficiency across broad wavelength range suitable for monolithic integration in photonics circuits.
