A new way of rapidly identifying bacteria, which requires a slight modification to a simple microscope, may change the way doctors approach treatment for patients who develop potentially deadly infections and may also help the food industry screen against contamination with harmful pathogens, according to researchers at the Korea Advanced Institute of Science and Technology (KAIST).

Evolving Electron Microscopes Push Even Deeper

June 3, 2015 2:58 pm | by Tim Studt | Articles | Comments

Electron microscopy is a multi-scale, multi-modal and multi-dimensional technique for imaging materials down to the atomic level. Developed in 1931 by German physicist Ernst Ruska and electrical engineer Max Knoll, the electron microscope (EM) has evolved from Ruska’s initial 400X capabilities to its current 10,000,000X performance.

Seeing the action

May 27, 2015 7:47 am | by Sonia Fernandez, Univ. of California, Santa Barbara | News | Comments

Cells are biological wonders. Throughout billions of years of existence on Earth, these tiny units of life have evolved to collaborate at the smallest levels in promoting, preserving and protecting the organism they comprise. Among these functions is the transport of lipids and other biomacromolecules between cells via membrane adhesion and fusion.

CLAIRE brings electron microscopy to soft materials

May 14, 2015 12:37 pm | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

Soft matter encompasses a broad swath of materials, including liquids, polymers, gels, foam and biomolecules. At the heart of soft materials, governing their overall properties and capabilities, are the interactions of nano-sized components. Observing the dynamics behind these interactions is critical to understanding key biological processes.

Researchers build new fermion microscope

May 14, 2015 7:50 am | by Jennifer Chu, MIT News Office | News | Comments

Fermions are the building blocks of matter, interacting in a multitude of permutations to give rise to the elements of the periodic table. Without fermions, the physical world would not exist. Examples of fermions are electrons, protons, neutrons, quarks and atoms consisting of an odd number of these elementary particles. Because of their fermionic nature, electrons and nuclear matter are difficult to understand theoretically. 

Electrons corralled using new quantum tool

May 7, 2015 3:22 pm | by David L. Chandler, MIT News Office | News | Comments

Researchers have succeeded in creating a new “whispering gallery” effect for electrons in a sheet of graphene, making it possible to precisely control a region that reflects electrons within the material. They say the accomplishment could provide a basic building block for new kinds of electronic lenses, as well as quantum-based devices that combine electronics and optics.

Researchers match physical and virtual atomic friction experiments

May 7, 2015 12:00 pm | by Evan Lerner, Univ. of Pennsylvania | News | Comments

Technological limitations have made studying friction on the atomic scale difficult, but researchers at the Univ. of Pennsylvania and the Univ. of California, Merced, have now made advances in that quest on two fronts. By speeding up a real atomic force microscope and slowing down a simulation of one, the team has conducted the first atomic-scale experiments on friction at overlapping speeds.

Promising x-ray microscope poses technical challenges

May 1, 2015 10:08 am | by Breanna Bishop, Lawrence Livermore National Laboratory | News | Comments

You may think the aisles in your neighborhood convenience store are crowded, but they’d look positively spacious compared to the passageways in the NIF target bay. The target bay bristles with dozens of instruments needed for NIF experiments, ranging from inserters that hold NIF targets in place to cameras and other diagnostics that record the results of NIF shots.

Unique microscopic images provide new insights into ionic liquids

April 28, 2015 11:47 am | by Kiel University | News | Comments

To directly observe chemical processes in unusual, new materials is a scientific dream, made possible by modern microscopy methods: researchers at Kiel University have, for the first time, captured video images of the attachment of molecules in an ionic liquid onto a submerged electrode. The images from the nanoscale world provide detailed information on the way in which chemical components reorganize when a voltage is applied.

Quantum ‘paparazzi’ film photons in the act of pairing up

April 23, 2015 11:34 am | by University of Warsaw | News | Comments

In the quantum world of light, being distinguishable means staying lonely. Only those photons that are indistinguishable can wind up in a pair, through what is called Hong-Ou-Mandel interference. This subtle quantum effect has been successfully imaged for the first time by two doctoral students from the Faculty of Physics at the University of Warsaw.

Much like magnetic resonance imaging is able to scan the interior of the human body, the emerging technique of "picosecond ultrasonics," a type of acoustic imaging, can be used to make virtual slices of biological tissues without destroying them. Now, a team of researchers in Japan and Thailand has shown that picosecond ultrasonics can achieve micron resolution of single cells, imaging their interiors in slices separated by 150 nm.

An eruption of lithium at the tip of a battery's electrode, cracks in the electrode's body and a coat forming on the electrode's surface reveal how recharging a battery many times leads to its demise. Using a powerful microscope to watch multiple cycles of charging and discharging under real battery conditions, researchers have gained insight into the chemistry that clogs rechargeable lithium batteries.

Optical method for producing high-res, 3-D images of nanoscale objects

April 8, 2015 8:07 am | by Bjorn Carey, Stanford Univ. | Videos | Comments

To design the next generation of optical devices, ranging from efficient solar panels to LEDs to optical transistors, engineers will need a 3-D image depicting how light interacts with these objects on the nanoscale. Unfortunately, the physics of light has thrown up a roadblock in traditional imaging techniques: The smaller the object, the lower the image's resolution in 3-D.

Pseudogenes, a subclass of long noncoding RNA  that developed from the human genome’s 20,000 protein-coding genes but has lost the ability to produce proteins, have long been considered nothing more than genomic junk.

Multi-scale Fractal-based Methods for Useful Characterizations of Surface Topographies

March 30, 2015 12:05 pm | by Christopher Brown, Surface Metrology Lab, Worcester Polytechnic Institute | Articles | Comments

Geometrically, fractals have forms, or features, that repeat at different sizes over ranges of scales. These features can repeat exactly, such as the triangles that repeat with scale on a Koch snowflake or Minkowski sausage. Or, these features might repeat statistically, as on ground or abraded surfaces, where these repeating features create self-similar patterns of scratches or over a range of scales.

Sewage could be a source of valuable metals, critical elements

March 23, 2015 8:42 am | by American Chemical Society | News | Comments

Poop could be a goldmine, literally. Surprisingly, treated solid waste contains gold, silver and other metals, as well as rare elements such as palladium and vanadium that are used in electronics and alloys. Now researchers are looking at identifying the metals that are getting flushed and how they can be recovered. This could decrease the need for mining and reduce the unwanted release of metals into the environment.

Sharper nanoscopy

March 19, 2015 2:16 pm | by Phillip Schewe, Joint Quantum Institute | News | Comments

The 2014 chemistry Nobel Prize recognized important microscopy research that enabled greatly improved spatial resolution. This innovation, resulting in nanometer resolution, was made possible by making the emitter of the illumination quite small and by moving it quite close to the object being imaged. One problem with this approach is in such proximity, the emitter and object can interact with each other, blurring the resulting image.
