Researchers developed a universal method to fabricate van der Waals heterostructures into nano-opto-electro-mechanical systems. The team demonstrated various functionalities, including nano-mechanical resonators, vacuum channel diodes, and ultra-fast thermo-radiators.
Scientists have deciphered the helmeted honeyeater's genome and created a genetic map to guide advanced genetic rescue methods. The new tools allow for precise breeding decisions, reducing inbreeding and its negative impact on population health.
Researchers have developed a new type of meta-imager that enables arbitrary all-optical convolution for AI and image processing. The meta-imager combines a metalens with a complex-amplitude modulator to perform convolutional operations in parallel, at the speed of light.
Researchers create a desorption-tailoring strategy to realize efficient p-doping in Al-rich AlGaN, achieving a high hole concentration of 8.1×10^18 cm^-3 at room temperature. The approach also enables vertical miniband transport of holes, satisfying device requirements.
A multicenter study found mutations in the SARS-CoV-2 N protein associated with increased viral loads and severe disease symptoms. The changes enabled the virus to hijack host cell translation machinery, leading to a life-threatening cytokine storm.
A new study reports a 0.92-year decline in global life expectancy from 2019 to 2020, the first since 1950, due to COVID-19. Life expectancy stabilized by 2021 but was still two years lower than expected.
A study found that older people are more positively reactive to emotional stimuli and better at reframing negative experiences into positives. Despite a decline in basal negative affect with age, participants were able to extract more positivity from given negative situations.
