More efficient molecular motor widens potential applications

Depiction of the structural changes during 4-step unidirectional isomerization of 1st generation aldehyde motor with key features above the reaction arrows. Starting from top left, UV light induces photoisomerization to reach the top-right state with more than 95 percent efficiency. This top-right state transforms by a unidirectional thermal ‘helix inversion’ step (THI) to the version …

Cells may possess hidden communication system

Cells constantly navigate a dynamic environment, facing ever-changing conditions and challenges. But how do cells swiftly adapt to these environmental fluctuations? A new Moffitt Cancer Center study, published in iScience, is answering that question by challenging our understanding of how cells function. A team of researchers suggests that cells possess a previously unknown information processing …

High-pressure synthesis of rubidium niobate

The researchers investigated crystal structure and properties of perovskite-RbNbO3 prepared at 4 GPa. Single-crystal XRD analysis revealed RbNbO3 exhibits the same non-centrosymmetric space group as ferroelectrics BaTiO3 and KNbO3. Credit: Ayako Yamamoto from SIT, Japan Capacitors are crucial components in electronic devices such as smartphones and computers. They are made of dielectric materials that polarize …

A systematic review of three key sugar metabolism proteins: HXK, SnRK1 and TOR

HXK, SnRK1 and TOR signaling networks in plant growth and development. Credit: The authors Sugar signaling is one of the most important regulatory signals for plant growth and development, and its metabolic network contains many regulatory factors. Sugar signaling molecules regulate cellular activities and organismal development by interacting with other intrinsic regulators and environmental cues. …

Food in sight? The liver is ready!

What happens in the body when we are hungry and see and smell food? A team of researchers at the Max Planck Institute for Metabolism Research has now been able to show in mice that adaptations in the liver mitochondria take place after only a few minutes. Stimulated by the activation of a group of …
