Dynamic In‐Situ Experimentation on Nanomaterials at the Atomic Scale

19-Feb-2015 | Tao Xu, Litao Sun, Small, 2015

With the development of in situ techniques inside transmission electron microscopes (TEMs), external fields and probes can be applied to the specimen. This development transforms the TEM specimen chamber into a nanolab, in which reactions, structures, and properties can be activated or altered ...

Mission (im)possible – mapping the brain becomes a reality

01-Feb-2015 | Anna Lena Eberle; Olaf Selchow; Marlene Thaler; Dirk Zeidler; Robert Kirmse, Journal of Electron Microscopy, 2015

Charting and understanding the full wiring diagram of complex neuronal structures such as the central nervous system or the brain (Connectomics) is one of the big remaining challenges in life sciences. Although at first it appears nearly impossible to map out a full diagram of, e.g., a mouse ...

Connectomics: comprehensive approaches for whole-brain mapping

01-Feb-2015 | Shinsuke Shibata; Yuji Komaki; Fumiko Seki; Michiko O. Inouye; Toshihiro Nagai; Hideyuki Okano, Journal of Electron Microscopy, 2015

The aim of connectomics analysis is to understand whole-brain neural connections. This is accomplished using new biotechnologies. Here, we provide an overview of the recent progress in connectomics analysis. The entire neural network of an organism was revealed for the first time in the nematode. ...

[Report] Expansion microscopy

30-Jan-2015 | Fei Chen; Paul W. Tillberg; Edward S. Boyden, Science , 2015

In optical microscopy, fine structural details are resolved by using refraction to magnify images of a specimen. We discovered that by synthesizing a swellable polymer network within a specimen, it can be physically expanded, resulting in physical magnification. By covalently anchoring specific ...

Blown-up brains reveal nanoscale details

15-Jan-2015 | Callaway, Ewen;, Nature, 2015

Blown-up brains reveal nanoscale details Nature 517, 7534 (2015). http://www.nature.com/doifinder/10.1038/nature.2015.16667 Author: Ewen Callaway Material used in diaper absorbant can make brain tissue bigger and enable ordinary ...

Inter‐laboratory comparison of a WDS–EDS quantitative X‐ray microanalysis of a metallic glass

01-Dec-2014 | Philippe Jonnard, François Brisset, Florence Robaut, Guillaume Wille, Jacky Ruste, X-Ray Spectrometry, 2014

We conducted an inter‐laboratory study of a metallic glass whose main component is nickel. Two determinations of the mass fractions of the different elements present within the sample were asked to the participants: one at an acceleration voltage of 15 or 20 kV and another one at 5 kV. We ...

Two-Dimensional Imaging of Fast Intracellular Ca2+ Release

01-Dec-2014 | Tian, Q., Kaestner, L., Lipp, P., CSH Protocols, 2014

Asynchronous release of calcium (Ca2+)—for example, the generation of Ca2+ alternans in cardiac myocytes—is a phenomenon important in the development of cardiac arrhythmogenesis. The development of a failure to release Ca2+ at individual release sites can be regarded as a major contributor to ...
