Metabolomic sweet spot clock predicts mortality and age-related diseases in the Canadian Longitudinal Study on Aging

Vishnyakova et al. develop a metabolomic aging biomarker based on optimal metabolite levels, or “sweet spots.” They show that this biomarker predicts mortality and the onset of age-related diseases.

1-nm-thick epitaxial AlN passivation for highly efficient flexible InGaN red micro-LEDs

Kong et al. report 1-nm-thick epitaxial AlN passivation for 1.5-µm-diameter InGaN red micro-LEDs by Ar plasma assisted atomic layer deposition, resulting in an efficiency of 6.5% at 649 nm. A near-complete device transfer to polyimide substrates further enables high-resolution flexible micro-LEDs.

High-capacity methane storage in flexible alkane-linked porous aromatic network polymers

Adsorbing natural gas in porous materials is a potential storage alternative to conventional approaches based on liquefaction or compression, but higher capacities are required for commercial viability. Here, the authors employ porous covalent organic polymers that are flexible but robust, leading to high storage capacities and cyclability.

Wafer-scale alignment and integration of micro-light-emitting diodes using engineered van der Waals forces

By engineering the upper and lower surfaces of micro-light-emitting-diode chips to have different van der Waals forces, hundreds and thousands of chips can be accurately aligned on substrates and used to create active-matrix displays.

The effects of genetic and modifiable risk factors on brain regions vulnerable to ageing and disease

A network of brain regions degenerates earlier in aging. Here the authors show that, this network is most vulnerable to diabetes, traffic-related pollution and alcohol consumption in terms of risk factors for dementia, and associated with the XG blood group genes.

Electrically driven mid-submicrometre pixelation of InGaN micro-light-emitting diode displays for augmented-reality glasses

Submicrometre-sized InGaN-based light-emitting diodes are fabricated by tailored ion implantation. The devices are free from electrical leakage and show a luminance of 7,440 nit at 4.9 A cm⁻² even at the line/space scale of 0.5/0.5 μm (= 8,500 ppi).
