When does a conductor not conduct?      (via sciencedaily.com)     Original source 

A new study uncovers a switchable, atomically-thin metal-organic material that could be used in future low-energy electronic technologies. The study shows that electron interactions in this material create an unusual electrically-insulating phase in which electrons are 'frozen'. By reducing the population of electrons, the authors are able to unfreeze the remaining electrons, allowing for controlled transitions between insulating and electrically-conductive phases: the key to the on-off binary operations of classical computing.

From disorder to order: Flocking birds and 'spinning' particles      (via sciencedaily.com)     Original source 

Researchers have demonstrated that ferromagnetism, an ordered state of atoms, can be induced by increasing particle motility and that repulsive forces between atoms are sufficient to maintain it. The discovery not only extends the concept of active matter to quantum systems but also contributes to the development of novel technologies that rely on the magnetic properties of particles, such as magnetic memory and quantum computing.

AI deciphers new gene regulatory code in plants and makes accurate predictions for newly sequenced genomes      (via sciencedaily.com)     Original source 

Elucidating the relationship between the sequences of non-coding regulatory elements and their target genes is key to understanding gene regulation and its variation between plant species and ecotypes. Now, an international research team developed deep learning models that link gene sequence data with mRNA copy number for several plant species and predicted the regulatory effect of gene sequence variation.

A shortcut for drug discovery      (via sciencedaily.com)     Original source 

For most human proteins, there are no small molecules known to bind them chemically (so called 'ligands'). Ligands frequently represent important starting points for drug development but this knowledge gap critically hampers the development of novel medicines. Researchers at CeMM, in a collaboration with Pfizer, have now leveraged and scaled a method to measure the binding activity of hundreds of small molecules against thousands of human proteins. This large-scale study revealed tens of thousands of ligand-protein interactions that can now be explored for the development of chemical tools and therapeutics. Moreover, powered by machine learning and artificial intelligence, it allows unbiased predictions of how small molecules interact with all proteins present in living human cells. These groundbreaking results have been published in the journal Science (DOI: 10.1126/science.adk5864), and all generated data and models are freely available for the scientific community.

Towards novel promising perovskite-type ferroelectric materials: High-pressure synthesis of rubidium niobate      (via sciencedaily.com)     Original source 

Researchers have pioneered a breakthrough in ferroelectric material development. They've engineered a novel displacement-type ferroelectric material boasting remarkable dielectric properties. Their achievement includes the successful synthesis of rubidium niobate (RbNbO3), a compound previously deemed challenging to produce under pressures exceeding 40,000 atmospheres. Additionally, they characterized how polarization changes across a wide temperature range during phase transitions. This breakthrough can lead to new design guidelines for ferroelectric materials.

The secret to saving old books could be gluten-free glues      (via sciencedaily.com)     Original source 

'Bookworm' is a cute thing to call a voracious reader, but actual bookworms -- as well as microorganisms and time -- break down the flour pastes commonly used to keep old publications in one piece. Now, researchers have analyzed the proteins in wheat-based glues applied in historic bookbinding to provide insights on their adhesiveness and how they degrade. This information could help conservators restore and preserve treasured tomes for future generations.
