Due to the fact that the radioisotopes used to power nuclear batteries are generally produced in nuclear reactors, ...

In this way, the positions to be measured in the macromolecule could be marked with a single fluorescent molecule and ...

There’s an old joke that you can’t trust atoms — they make up everything. But until fairly recently, there was no real way to see individual atoms. You could infer things about them using X ...

An angstrom (Å) is a unit of length equal to 10-10 meters or 0.1 nanometers. It is named after the Swedish physicist Anders Jonas Ångström, who first used it to measure the wavelengths of light. The ...

The first half of 20th-century science belonged to physics, with the general theory of relativity, quantum mechanics, and nuclear fission. The second half would belong to biology. In the post-war ...

Single molecule studies are increasingly important in biophysics. The Perkins group focuses on developing precision single-molecule techniques and applying them to answer a variety of biological ...

Running for a criminally short six episodes in 1982, Police Squad! spawned Detective Frank Drebin, played by Leslie Nielsen. While the show never got a second series, it gained a cult following ...

John Warlaumont, vice president of advanced technologies at SEMATECH, a consortium of the world's chip manufacturers, talks to Nadya Anscombe about the future of optical lithography. Most ...

Single-molecule biophysics is the study of the dynamics and interactions of individual biomolecules to understand how they carry out their functions in living cells. For example, monitoring the ...

The intra-molecular resolution achieved with MINFLUX microscopy makes it possible to optically record the spatial distances between subunits in macromolecules and thus to detect different ...

A team led by physicists Steffen Sahl and Stefan Hell at the Max Planck Institute (MPI) for Multidisciplinary Sciences in Göttingen and the MPI for Medical Research in Heidelberg has succeeded in ...
