Author:. C Parmenter. Meeting Report - CMG 31. Mid-November in the UK Cryo microscopy community is synonymous with the annual Cryo Microscopy Group (CMG) meeting. November 2019 was no different and saw a diverse line up of speakers share their latest achievements at the University of Nottingham with a receptive and enthustic audience. The first speaker Thomas Braun from the University of Basel presented his work on revolutionary which uses nanolitre deposition onto EM grids for the purpose of preparing thin films of solutions. The use of a microcapilary technology for the deposition and microfluidics for solution mixing and sample extraction combine to give a very powerful sample preparation technique. Thomas presented this using the title sin.

Deep learning restores under-sampled images. Submitted by. user_64683. on 15 January, 2020. Rebecca Pool. Published date:. Wednesday, January 15, 2020 - 15:00. Image: Side by side restoration results of electron microscopy images. [Salk Institute]. Using deep learning, US-based researchers have devised a method to accelerate neuroimaging by up to sixteen times. The new imaging method, called point-scanning super-resolution (PSSR) imaging, can restore under-sampled SEM and laser scanning confocal microscopy images, overcoming the resolution, speed, and sensitivity trade-off issues associated with point-scanning image acquisition. “Not only does this approach work, but our training model can be used right away," says , Director of the at the in San

Grown in the lab: miniature brain tumour. Submitted by. user_64683. on 15 January, 2020. Rebecca Pool. Published date:. Wednesday, January 15, 2020 - 12:30. Image: A model brain tumour with blood vessels grown in the lab. [Agavi Stavropoulou-Tatla]. UK-based researcher, , has unveiled a stunning image of a mini brain tumour with blood vessels, grown in the lab. So-called tumouroids are miniature versions of tumours grown in laboratories to offer a robust platform for the development of personalised therapies. Stavropoulou-Tatla is currently studying for her PhD, and as she says: “This biomimetic model could provide insight into the mechanisms that drive tumour new blood vessel formation and invasion along blood vessels, and serve as a personalised.

Steel embrittlement mystery solved. Submitted by. user_64683. on 13 January, 2020. Rebecca Pool. Published date:. Monday, January 13, 2020 - 22:30. Image: Atom probe tomography reveals how hydrogen (red) at carbon-rich (blue) dislocations in steel. [University of Sydney]. In a breakthrough for a future hydrogen economy, Australia-based researchers have discovered new evidence of how hydrogen embrittlement in high-strength steel takes place, and importantly, how to prevent it. While hydrogen atoms tend to diffuse and accumulate at dislocations and grain boundaries in a steel, cryogenic atom probe microscopy results, published in , have shown exactly how niobium carbide clusters within its microstructure help to trap the hydrogen, reduce embrittleme.

World's first monolayer amorphous film created. Submitted by. user_64683. on 09 January, 2020. Rebecca Pool. Published date:. Thursday, January 9, 2020 - 21:45. Image: Researchers at the National University of Singapore have synthesised the world's first atomically thin amorphous carbon film. Researchers from the have synthesised the world's first one-atom-thick amorphous material. Atomic resolution imaging revealed the complete absence of long-range periodicity in the monolayer amorphous carbon (MAC), which the researchers hope will settle decades-old debate of exactly how atoms are arranged in amorphous solids. "With MAC, we have shown for the first time that fully amorphous materials can be stable and free-standing in single atomic layers,” sa.

When it comes to imaging, ’s first love was electron microscopy at a time when it seemed the world was edging towards confocal methods. It was the late 1980s, the University of Bristol Professor of Bioimaging and academic lead of advanced electron microscopy at the was about to embark on his PhD, and the biological marker, green fluorescent protein, was rising in popularity amongst biologists. "This was when many electron microscopy labs were actually closing as GFP was coming online," he says.

Author:. Dalia Yablon Ph.D. Machine learning 3: the importance of subject matter expertise. One of the doomsday prophecies often heard in popular culture and media is that ML is going to. . It is easy to get that impression because there are certain, I would say even narrow, set of areas that ML can perform very well. However, it has significant weaknesses that prevent some kind of widespread implementation on all tasks. Human experts in physics, chemistry, engineering, medicine, biology, material science, mathematics etc are at the core of proper development, continuous monitoring, and feedback needed in development and implementation of such algorithms There is a continual need for human intervention beyond the initial algorithm development t.
