New Label-Free Imaging Technique Set to Revolutionize Biomedical Imaging

The key to this new chemical imaging technique is the use of two lasers with different frequencies. Researchers visualize samples by tuning the laser frequencies to match the vibrational frequency of a specific chemical bond. Each type of molecule within a sample, including nutrients or drugs, is detectable at a unique frequency.

New Centrifugation Method Capable of Separating Carbon Nanotubes

Double-walled carbon nanotubes (DWNTs) can be separated from mixtures of single- (SWNTs) and multiwalled nanotubes (MWNTs) by using a centrifugation method recently developed at Northwestern University

Animation Reveals the Mysterious Properties of the Quantum World

Quantum physics is both mysterious and difficult to grasp. Barry Sanders, director of the University of Calgary's Institute for Quantum Information Science, is hoping to change that.

Introducing NanoArt Online Competition - A New Art Discipline

NanoArt is a new art discipline at the art-science-technology intersections. It features nanolandscapes (molecular and atomic landscapes which are natural structures of matter at molecular and atomic scales) and nanosculptures (structures created by scientists and artists by manipulating matter at molecular and atomic scales using chemical and physical processes).

New "Super-Resolution" Fluorescence Microscopy Technique Reveal Features of Cells at 20-30 nanometers (nm)

Thanks to a new "super-resolution" fluorescence microscopy technique, Harvard University researchers have succeeded in resolving the features of cells as miniscule as 20-30 nanometers (nm), an order of magnitud...

Scientists Now Able to Observe Membrane Fission in Real Time

Researchers at The Scripps Research Institute have solved one of biology's neatest little tricks: they have discovered how a cell's outer membrane pinches a little pouch from itself to bring molecules outside the cell inside—without making holes that leak fluid from either side of the membrane.

New Method to Electrically Characterize Individual Carbon Nanotubes

A single batch of carbon nanotubes -- molecular carbon cylinders that may one day revolutionize electronics engineering -- often includes more than 100 types of tubes, each with different optical and electrical properties. Individual electrical measurements of the molecules typically require such slow and expensive methods as electron-beam lithography.

Microbial Ecosystem Sheds New Light on Climate Change

MIT researchers have created a microbial ecosystem smaller than a stick of gum that sheds new light on the plankton-eat-plankton world at the bottom of the aquatic food chain. The work, reported in the January print i...

Creating Virus-Like Particle-Based Vaccines More Quickly and Accurately than Previously Possible

In a pioneering effort, researchers at the National Institute of Standards and Technology (NIST) and the University of Queensland in Australia have successfully demonstrated* that they can count, size and gauge the quality of virus-like particle-based (VLP) vaccines much more quickly and accurately than previously possible.
