Scientists at Inserm, CNRS and the Université de Montpellier at the Structural Biology Center in Montpellier, France have built a small robot entirely from DNA and are using it to study cell processes that are invisible to the naked eye.

Chemists at ETH Zurich have found a facile method that allows a commonly used building block to be directly converted into other types of important compounds. This expands the possibilities of chemical synthesis and facilitates the search for new pharmaceutically active ingredients.

Scientists from ETH Zurich’s Macromolecular Engineering and Organic Chemistry Labs and entrepreneurs from Colorado-based Nanoly Bioscience worked together to develop a safe, versatile platform to increase the thermal stability of vaccines. Their aim? To vastly improve the distribution of viable vaccines and reduce the economic costs of the cold chain.

Researchers from China explored a new treatment method for inflammatory bowel disease using ultrasmall Au25 — gold — nanoparticles. In previous studies, these nanoclusters have been found to effectively eliminate a variety of reactive oxygen species, a type of free radical molecule that can build up and damage DNA, RNA and proteins in a cell.

Researchers from Osaka University and collaborating partners have measured temperature gradients within cells at unprecedented precision. This development will help test long-contentious medical hypotheses and inspire drug development.

Northwestern University chemists have done the seemingly impossible. Using low temperatures and inexpensive, common reagents, the research team developed a process that causes two major classes of PFAS compounds to fall apart — leaving behind only benign end products.

Of the many contemporary conveniences often taken for granted in developed countries, modern sanitation may be among the most important. A new study suggests that wastewater infrastructure may provide societal benefits far beyond the dramatic improvements in community hygiene. The research highlights a technique known as Wastewater-based Epidemiology.

Scientists from UC Riverside are studying how the popular keto and intermittent fasting diets work on a molecular level, and whether both sexes benefit from them equally.

By combining microscopy, biochemistry techniques and artificial intelligence, researchers at University of California San Diego School of Medicine and collaborators have taken what they think may turn out to be a significant leap forward in the understanding of human cells.

When does a cell become a cancer cell? And how can cancer be eliminated in a targeted manner? These questions are to be answered by a computer model developed by researchers at TU Graz, which for the first time simulates the membrane potentials of a cancer cell.
