Hydrogen spillover is exactly what it sounds like. Small metal nanoparticles anchored on a thermally stable oxide, like silica, comprise a major class of catalysts, which are substances used to accelerate chemical reactions without being consumed themselves. The catalytic reaction usually occurs on the reactive -- and expensive -- metal, but on some catalysts, hydrogen atom-like equivalents literally spill from the metal to the oxide. These hydrogen-on-oxide species are called 'hydrogen spillover.'

A main crux of neuroscience is learning how our senses translate light into sight, sound into hearing, food into taste, and texture into touch. Smell is where these sensory relationships get more complex and perplexing. To address this question, a research team are investigating how airborne chemicals connect to odor perception in the brain. They discovered that a machine-learning model has achieved human-level proficiency at describing, in words, what chemicals smell like.

By controlling the arrangement of multiple inorganic and organic layers within crystals using a novel technique, researchers have shown they can control the energy levels of electrons and holes (positive charge carriers) within a class of materials called perovskites. This tuning influences the materials' optoelectronic properties and their ability to emit light of specific energies, demonstrated by their ability to function as a source of lasers.

Patulin is a harmful mycotoxin produced by fungi typically found in damaged fruits, including apples, pears, and grapes. In a recent breakthrough, researchers identified a new filamentous fungal strain that can degrade patulin by transforming it into less toxic substances. Their findings provide important insights into the degradation mechanisms for patulin found in nature, and can lead to new ways of controlling patulin toxicity in our food supplies.

A team of researchers addressed the question: what happens to a Ga-promoted Cu surface under reaction conditions required for the synthesis of methanol? They found complex structural transformations of this bimetallic catalyst that might change the common view on the catalytically active surface structure.

Researchers have been able to substantially improve photoclick chemistry. They were able to boost the reactivity of the photoclick compound in the popular PQ-ERA reaction through strategic molecular substitution. They now report a superb photoreaction quantum yield, high reaction rates and notable oxygen tolerance.

Nanofitins, which are derived from a protein in an archaeal microorganism found in hot springs -- successfully neutralized SARS-CoV-2 in mice and were well-tolerated. When inhaled by the rodents, the engineered nanofitins, which inhibit the virus by binding to its spike proteins, were observed to quickly reach the lungs in high doses both preventing and clearing early infections, researchers report.

Researchers have developed a miniature battery that could be used to power tiny devices integrated into human tissues. The design uses an ionic gradient across a chain of droplets -- inspired by how electric eels generate electricity. The device was able to regulate the biological activity of human neurons. This could open the way to the development of tiny bio-integrated devices, with a range of applications in biology and medicine.

We've long known that hosts malfunction without their microbiome -- whether they are missing key microbial species or are completely microbe free. This malfunctioning is usually explained by the need for microbes to perform unique and beneficial functions, but evolutionary ecologist is questioning that narrative.
