17:33 A new method to form a lens for atomic-resolution electron microscopes

Electron microscopy enables researchers to visualize tiny objects such as viruses, the fine structures of semiconductor devices, and even atoms arranged on a material surface. Focusing down the electron beam to the size of an atom is vital for achieving such high spatial resolution. However, when the electron beam passes through an electrostatic or magnetic lens, the rays of electrons exhibit different focal positions depending on the focusing angle and the beam spreads out at the focus. Correcting this "spherical aberration" is costly and complex, meaning that only a select few scientists and companies possess electron microscopes with atomic resolution.

The observation was conducted using the newly developed Magnetic-field-free Atomic-Resolution STEM (MARS). This team had already succeeded in observing the electric field inside atoms for the first time in 2012. However, since the magnetic fields in atoms are extremely weak compared with electric fields, the technology to observe the magnetic fields had been unexplored since the development of electron microscopes. This is an epoch-making achievement that will rewrite the history of microscope development.

15:03 Solving the ice problem in cryo-electron microscopy

Cryo-EM requires protein samples to be frozen before they are imaged using an electron microscope. This revolutionary technique and its application to structural biology was the focus of the Nobel Prize for Chemistry in 2017 and has contributed to a wave of new structural information for proteins that were difficult or impossible to prepare for X-ray crystallography. As cryo-EM became more popular, new methods and tools arose to improve the technique and make it more efficient. Now, many people are working on the way that samples are prepared so that this is easier to get high resolution structural information from each experiment. Once samples are prepared, there are a number of automated tools that have been developed for picking the frozen particles to be processed. It was while investigating these tools that Ph.D. student Mateusz Olek and his supervisor Peijun Zhang with help from Yuriy Chaban and Donovan Webb, uncovered an unusual problem.

To improve our understanding of biomolecular processes happening within cells, techniques for visualizing and recording them are of key importance. High-speed atomic-force microscopy (HS-AFM) has become an important technique for the real-time observation of biological processes on the sub-molecular spatial scale and with sub-second time resolution. Still, a higher video frame rate is required for recording many important processes, such as ion transport motion or signaling mechanisms within membranes. Now, Kenichi Umeda, Toshio Ando and Noriyuki Kodera from Kanazawa University and colleagues have designed an amplitude detector with ultrafast operation, the use of which in HS-AFM leads to a significantly improved temporal resolution.

15:33 First atomic model of human telomerase constructed by electron cryo-microscopy

Telomeres are large nucleoproteins structures that cap the ends of chromosomes in eukaryotic cells. When a cell divides, a small portion of the telomere is lost due to the inherently incomplete process of genome replication. If left unchecked, over time the telomeres will reach a critically short length and the cell will face genomic instability, deterioration or death. To offset this shortening, an essential enzyme called telomerase rebuilds the telomeres by synthesizing new telomeric DNA repeats at chromosome ends. Kelly Nguyen's group, in the LMB's Structural Studies Division, has solved the first complete atomic model of this enzyme and discovered a histone dimer as novel telomerase subunits.

18:57 Understanding Complex Magnetic Spin Textures with Simulation-Assisted Lorentz Transmission Electron Microscopy

Author(s): Arthur R.C. McCray, Timothy Cote, Yue Li, Amanda K. Petford-Long, and Charudatta PhatakLorentz transmission electron microscopy (LTEM) is frequently used to image magnetic induction maps of topological magnetic spin structures. These induction maps are visually intuitive, but can be misinterpreted for materials in which the magnetization differs greatly from the integrated induction, leading to ambiguous determination of spin structures. The authors present PyLorentz, their open-source software for simulating LTEM images from three-dimensional micromagnetic simulations. By applying the technique to Néel skyrmions, they demonstrate that combining simulated and experimental LTEM images gives a more complete picture of complex spin structures. [Phys. Rev.
