Published Scientists solve chemical mystery at the interface of biology and technology
(via sciencedaily.com) Original source Organic electrochemical transistors (OECTs) allow current to flow in devices like implantable biosensors. But scientists long knew about a quirk of OECTs that no one could explain: When an OECT is switched on, there is a lag before current reaches the desired operational level. When switched off, there is no lag. Current drops immediately. Researchers report that they have discovered the reason for this activation lag, and in the process are paving the way to custom-tailored OECTs for a growing list of applications in biosensing, brain-inspired computation and beyond.

Published 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.
Published Getting dynamic information from static snapshots
(via sciencedaily.com) Original source Researchers have created TopicVelo, a powerful new method of using the static snapshots from scRNA-seq to study how cells and genes change over time. This will help researchers better study how embryos develop, cells differentiate, cancers form, and the immune system reacts.
Published 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.
Published Nanomaterial that mimics proteins could be basis for new neurodegenerative disease treatments
(via sciencedaily.com) Original source A newly developed nanomaterial that mimics the behavior of proteins could be an effective tool for treating Alzheimer's and other neurodegenerative diseases. The nanomaterial alters the interaction between two key proteins in brain cells -- with a potentially powerful therapeutic effect.
Published The longer spilled oil lingers in freshwater, the more persistent compounds it produces
(via sciencedaily.com) Original source Oil is an important natural resource for many industries, but it can lead to serious environmental damage when accidentally spilled. While large oil spills are highly publicized, every year there are many smaller-scale spills into lakes, rivers and oceans. The longer that oil remains in freshwater, the more chemical changes it undergoes, creating products that can persist in the environment.
Published 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.
