The Rise and Rise of Cryogenic Electron Microscopy

Speaking at the 68th Lindau Nobel Laureate meeting in Germany, biophysicist Joachim Frank says that the field of structural biology is entering a new era with a bright future thanks to advances in cryogenic electron microscopy. Cryo-EM rapidly freezes molecular samples in solution and images them with an electron beam to reveal the molecular structure. Today, resolutions of 3 to 4 Å are routinely achievable, while at its upper limits, the technique can achieve atomic resolutions of 2 Å.

Scientists Report Control of Electron Spins Connected to Superconductor

Scientists from the Niels Bohr Institute at the University of Copenhagen have, for the first time, succeeded in producing, controlling and understanding complex quantum states based on two electron spins connected to a superconductor. The samples, according to the study published in Nature Communications, were mounted in a dilution refrigerator with a base temperature near 30 mK and measured with standard techniques.
