In both biological and engineered systems, cells and sensors must make sense of noisy, changing signals to function. However, collecting and using this information consumes valuable energy. A new study, published in Physical ...
Deep in the ocean, brown algae and diatoms produce a complex carbohydrate molecule called fucoidan, which helps form their protective outer layers. The fucoidan molecule is very difficult for microbes to break down because ...
Chemical reactions are often written as simple equations: Starting materials go in, and a product comes out. In reality, the same substrates can follow many different pathways depending on their concentrations, temperature, ...
A single application of a "smart" self-repairing coating is being developed to dramatically extend rust protection for buildings, bridges, cars and other steel components.
Choosing an orbit for a satellite always comes with trade-offs. Very low Earth orbit (VLEO), between 100–450 km (62–280 miles), has distinct advantages. Remote-sensing cameras can take better pictures, communications and ...
A team of researchers from University of Toronto Engineering has created a new type of dye-sensitized nanoparticle that can detect target chemicals at very low concentrations while also distinguishing between molecules with ...
Metabotropic glutamate receptors, which are important but difficult drug targets, interact in surprisingly varied ways with their principal regulatory proteins, according to two new studies led by Weill Cornell Medicine investigators. ...
How can we predict the way a real material, such as a polymer, responds mechanically over timescales ranging from the ultrafast motion of atoms to the slow deformations measured in a laboratory? This is a deceptively difficult ...
Our cells' membranes have many functions. They not only provide mechanical protection but also precisely control which substances enter or leave cells. If they fail to perform these tasks, disease can result. Their structure ...
When a virus mutates, the world usually finds out the hard way. Variants of influenza and SARS-CoV-2 can slip past vaccines and antibody drugs before scientists fully understand what has changed. A new study from Harvard's ...
