Observation of the Smallest Three-Dimensional Neutral Boron Cluster.

Despite major progress in the investigation of boron cluster anions, direct experimental study of neutral boron clusters remains a significant challenge because of the difficulty in size selection. Here we report a size-specific study of the neutral B9 cluster using threshold photoionization with a tunable vacuum ultraviolet free electron laser. The ionization potential of B9 is measured to be 8.

The global, regional, and national patterns of change in the burden of bacterial pyoderma from 1990 to 2019 and the forecast for the next decade.

Pyoderma, commonly known as impetigo, is a bacterial skin infection causing pus formation, prevalent globally, especially in resource-poor areas. It affects both children and adults, including those with conditions like diabetes. Despite its significant impact and economic burden, research on its global epidemiology is limited.

Reductive stress: The key pathway in metabolic disorders induced by overnutrition.

Background: The balance of redox states is crucial for maintaining physiological homeostasis. For decades, the focus has been mainly on the concept of oxidative stress, which is involved in the mechanism of almost all diseases. However, robust evidence has highlighted that reductive stress, the other side of the redox spectrum, plays a pivotal role in the development of various diseases, particularly those related to metabolism and cardiovascular health.

Clonal Hematopoiesis of Indeterminant Potential as a Predictor of Colorectal Cancer Risk: Insights from the UK Biobank Cohort.

Background: Clonal hematopoiesis of indeterminate potential (CHIP) has been shown to be associated with the occurrence of solid tumors, but its relationship with colorectal cancer still needs to be studied.

Methods: We conducted a prospective matched case-control study using data from the UK Biobank, including 5,310 incident colorectal cancer (CRC) cases and 26,550 controls matched for age, sex, and body mass index (BMI).

Results: Analysis of the UK Biobank data revealed that the presence of CHIP was associated with an increased risk of CRC.

Rose-Inspired Adhesive Surface Regulation for Enhanced Fog Water Collection Efficiency and Self-Cleaning.

Inspired by the adhesion differences on the surfaces of fresh and dried rose petals, a rose bionic self-cleaning fog collector (RBSC) was designed and prepared to realize a self-driven fog harvesting function. The droplet detachment iteration rate was revealed by the regulating mechanism of the surface adhesion force of the RBSC and the influence of bionic texture parameters, as demonstrated through the fog harvesting experiment and droplet detachment failure analysis. Through the surface adhesion force regulation, the probability of droplet dissipation with the airflow is reduced by increasing the falling droplets' mass, and the single surface fog capture efficiency is up to 740 mg cm h.
