A cell sitting in fluid looks like one of the most passive things in biology. Nutrients drift toward it on the aimless currents of molecular motion, and now and then one bumps into the right spot on the cell's surface and ...
Predicting a system's final outcome from its initial state is the ultimate goal for many physicists. In certain complex systems, however, this goal is thwarted by chaos, where even the subtlest tweaks to the initial state ...
Molecules can be placed in a wide variety of quantum states. How can these states be distinguished in measurements when theoretical models are unreliable? Which excitation process lies behind which measurement signal?
Light sheet microscopy allows biologists to selectively light up a thin slice of a sample. This method can improve image contrast by reducing background light while remaining gentle on the sample, reducing photodamage and ...
In some materials, physical properties don't emerge from their individual particles, but from the collective behavior of their quantum spins. Now, researchers led by Pengcheng Dai at Rice University in the U.S. have discovered ...
Hydrogen is the simplest element in the periodic table, consisting of just one proton and one electron. In chemistry, however, the smallest of atoms is anything but simple. First produced by Nobel laureate Irving Langmuir ...
Many molecules in living organisms and pharmaceuticals share a structure called a β-amino alcohol, in which an amino group and a hydroxyl group sit on neighboring carbon atoms. These groups, important building blocks in biology ...
AI company Anthropic recently announced that its popular system Claude had identified an unusual family of biological molecules. These molecules were enzymes, a type of protein that speeds up chemical reactions in living ...
Producing textile fibers from wood involves extracting cellulose from a structure that is tougher and more resistant than that of grass. But what if grass offered an easier—and potentially more environmentally friendly—alternative? ...
Immune cells are the elite athletes of the human body. While other cells stay in place, immune cells travel throughout our bodies, squeezing through small channels, stretching themselves, sampling the surfaces of other cells ...
