Cool science: Researchers craft tiny biological tools using frozen ethanol

Imagine drawing on something as delicate as a living cell—without damaging it. Researchers at the University of Missouri have made this discovery using an unexpected combination of tools: frozen ethanol, electron beams and purple-tinted microbes.

An artificial protein that moves like something found in nature

Proteins catalyze life by changing shape when they interact with other molecules. The result is a muscle twitching, the perception of light, or a bit of energy extracted from food. But this crucial ability has eluded the growing field of AI-augmented protein engineering.

This may be of use
The Boltzmann-Gibbs statistical mechanics has limitations. For example, its predictions can fail when a system is in certain regimes, such as phase transitions or critical phenomena. For instance, statistical mechanics predicts the divergence of certain thermodynamic quantities at critical points, which is not observed experimentally. This has led to the development of the so-called "non-extensive statistical mechanics," a generalization of Boltzmann-Gibbs-von Neumann-Shannon statistical mechanics proposed by the Greek-Brazilian physicist Constantino Tsallis.

Laser technique improves ultra-high temperature ceramic manufacturing for space and defense applications

Researchers have demonstrated a new technique that uses lasers to create ceramics that can withstand ultra-high temperatures, with applications ranging from nuclear power technologies to spacecraft and jet exhaust systems.

Researchers have demonstrated a new technique that uses lasers to create ceramics that can withstand ultra-high temperatures, with applications ranging from nuclear power technologies to spacecraft and jet exhaust systems.

The technique can be used to create ceramic coatings, tiles or complex three-dimensional structures, which allows for increased versatility when engineering new devices and technologies.

The paper, "Synthesis of hafnium carbide (HfC) via one-step selective laser reaction pyrolysis from liquid polymer precursor," is published in the Journal of the American Ceramic Society.
