For telescopes operating in the vacuum of space, or optical equipment in extreme environments, existing coatings are often insufficient. In the Journal of Vacuum Science & Technology Aresearchers in China turned to atomic layer deposition and developed an ultrablack thin-film coating for aerospace-grade magnesium alloys. The team used alternating layers of aluminum-doped titanium carbide and silicon nitride and together the materials prevent nearly all light from reflecting off the coated surface. The coating absorbs 99.3% of light while being durable enough to survive in harsh conditions.

A new study offers potential insights into how and when we fill out March Madness brackets. The paper found that people are more risk seeking (more likely to predict a relatively improbable outcome) in their later forecasts and are thus more likely to make an incorrect prediction for them.
Pioneering research unveils lignin nanoparticles as potent UV-blocking agents, with their chemical structure and size effects extensively altering the sun protection efficacy of cosmetics. LNPs with tailored structures outperform conventional additives, offering enhanced UV resistance and eco-friendly solutions for skincare formulations.
The researchers carried out a hybridization experiment between female koi carp and male Chinese rare minnow, eventually obtaining allodiploid and allotriploid hybrid offspring. They made a systemic comparison between them and found that the triploid hybrids showed faster growth, higher expression of growth-promoting genes and lower expression of growth-inhibiting genes than the diploid hybrids. This study provides implications to explain the faster growth of polyploid fish.
A recent study has highlighted the insignificant health hazards posed by the emissions from waste-to-energy (WtE) facilities in China's Bohai Rim. This investigation brings to light the negligible impact of WtE plant emissions on public health, grounded in sophisticated regression analysis techniques.
This study discovers that upon induction of different autophagy processes, mitochondria immediately import calcium and calcium concentrations at the ER membrane start to fluctuate. The major calcium import channel in the inner mitochondrial membrane, mitochondrial calcium uniporter (MCU), is required for mitophagy-inducer-initiated mitochondrial calcium uptake. Inhibiting MCU accelerates mitophagy. In neurons derived from a Parkinson’s patient, mitophagy-inducer-triggered mitochondrial calcium influx is faster, which may slow the ensuing mitophagy.

The Portman lab at the Del Monte Institute for Neuroscience at the University of Rochester discovered that the male roundworms use pheromones and touch signals to determine the sex, age, nutritional health, and mating history of the hermaphrodites and show preference toward worms that have not previously mated with another male and are nutritionally healthy.
The best measurements from Hubble show the universe is now expanding faster than predicted based on observations of how it looked shortly after the big bang. Some scientists suggested that Hubble observations are wrong due to some creeping inaccuracy in its deep-space yardstick. However, Webb’s sharp infrared views of milepost markers known as Cepheids agree with Hubble data.
