Exploration of Key Factors in the Preparation of Highly Hydrophobic Silica Aerogel from Rice Husk Ash Assisted by Machine Learning.

To expand the applications of hydrophobic silica aerogels derived from rice husk ash (HSA) through simple traditional methods (without adding special materials or processes), this paper employs machine learning to establish mathematical models to identify optimal conditions for extracting water glass and investigates how preparation conditions and heat treatment temperatures affect properties such as the porosity and hydrophobicity of HSA. The results indicate that the decision tree regression model provides the most accurate predictions for the extraction rate and modulus of water glass. Notably, the water contact angle of HSA produced using nitric acid as a catalyst can reach as high as 159.

A previously reported bottleneck in human ancestry 900 kya is likely a statistical artifact.

It was recently reported that a severe ancient bottleneck occurred around 900 thousand years ago in the ancestry of African populations, while this signal is absent in non-African populations. Here, we present evidence to show that this finding is likely a statistical artifact.

Identification of TIGAR, a direct proteomic target associated with the hypoglycemic effect of Berberine.

Diabetes mellitus is a global chronic metabolic disease and the prevalence of diabetes mellitus is increasing dramatically every year. Berberine (BBR) from Coptidis Rhizoma has potent hypoglycemic effects, however, the specific proteins targeted by berberine that contribute to its hypoglycemic action remain to be elucidated. In this work, TIGAR (TP53-induced glycolysis and apoptosis regulator) was identified as a direct target protein for berberine using activity-based protein profiling (ABPP) and other chemical proteomics techniques with active photoaffinity probes as chemical tools.

Simultaneous visualization of lipid droplets and tracking of the endogenous hypochlorous acid in psoriatic mice models with a novel fluorescent probe in a wash-free fashion.

Conformational change-based fluorometric aptasensor for sensitive cadmium(II) detection in fruits and vegetables.

Cadmium (Cd) is a highly toxic heavy metal that can accumulate in the human body through contaminated food and water, posing great health risks. In this study, a label-free fluorescent aptasensor based on SYBR Green I (SGI) for the rapid and sensitive detection of Cd in food samples was designed. The aptasensor utilizes a Cd-specific aptamer (Cd-(21)) and its complementary strand (CS) to form a double-stranded DNA (dsDNA) structure in the absence of Cd.

Bacteria modulate microalgal aging physiology through the induction of extracellular vesicle production to remove harmful metabolites.

The bloom and bust patterns of microalgae in aquatic systems contribute massively to global biogeochemical cycles. The decline of algal blooms is mainly caused by nutrient limitation resulting in cell death, the arrest of cell division and the aging of surviving cells. Nutrient intake can re-initiate proliferation, but the processes involved are poorly understood.
