Seeing is believing: secrets of cells revealed

With the advancement of technology we are managing to see ever smaller and smaller pieces of the puzzle that is life. The August 2006 issue of Microbiology Today, the quarterly magazine of the Society for General Microbiology, looks at vital role that microscopy plays to advance our understanding of the lives of some fascinating micro-organisms.
Fluorescence microscopy as a research tool in bacterial cell biology
Jeff Errington takes a look at the revolutionary new views of the subcellular organization of bacteria provided by immunofluorescence, GFP and digital imaging.

Investigating a bacterial killer using atomic force microscopy

Atomic force microscopy is a powerful technique for studying biological surfaces and molecular structure. In their article, Megan Núñez and Eileen Spain tell us how they have applied AFM to study the secret life of the predatory killer, Bdellovibrio.

Viruses and intracellular movement

As we’ve seen with SARS and bird ‘flu, viruses seem to have few problems travelling across continents – they use their hosts! But how do viruses, which have no independent means of locomotion, manage to move within and between the cells of their host? Tom Wileman uses fluorescence microscopy to find out.

Studying single molecules in microbial systems

Recent advances in imaging technologies have enabled researchers to pinpoint individual molecules in living cells. Christoph Baumann describes two key bacterial enzyme complexes that have advanced our understanding of ‘nanoscopic’ motion.

Can you see the light?

Recent advances in fluorescence imaging have lead to some amazing findings, but the technical challenges and baffling array of options have tended to restrict new technologies to a limited few. Iain Hagan and colleagues look at simple and affordable steps to exploit these developments.

These are just some of the articles that appear, together with all the regular features and reports of Society activities.

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
