Folding paper microscope could reduce deaths from malaria

By - March 11, 2014 1 Picture
According to the World Health Organization, there were approximately 207 million cases of malaria worldwide in 2012, 627,000 of which proved fatal. Unfortunately, the disease most often occurs in developing nations, where diagnostic equipment may not be available. This means that doctors can't determine the particular strain of malaria from which a patient is suffering, and thus don't know which medication will work best. Manu Prakash, an assistant professor of bioengineering at the Stanford School of Medicine, hopes to change that ... using his disposable folding paper microscope. Read More

What shall we do with a neutron microscope?

By - October 20, 2013 10 Pictures
Neutrons have a set of unique properties that make them better suited than light, electrons, or x-rays for looking at the physics and chemistry going on inside an object. Scientists working out of MIT's Nuclear Reactor Laboratory have now invented and built a high-resolution neutron microscope, a feat that required developing new approaches to neutron optics.

Grad students build nanometer-resolution atomic force microscope using Lego and 3D printing

By - October 3, 2013 4 Pictures
Scanning atomic force microscopes, first introduced into commerce in 1989, are a powerful tool for nanoscale science and engineering. Capable of seeing individual atoms, commercial AFM prices range between US$10K and $1M, depending on the unit's features and capabilities. During the recent LEGO2NANO summer school held at Tsinghua University in Beijing, a group of Chinese and English students succeeded in making a Lego-based AFM in five days at a cost less than $500.

ProScope Micro Mobile lets your iPhone get mega-close-ups

By - April 26, 2013 7 Pictures
Optics manufacturer Bodelin is no stranger to hand-held microscopes, having previously brought us a series that can be connected to the USB port of a laptop. Given that smartphones are in many ways replacing laptops, however, it shouldn’t come as a surprise that the Oregon-based company has now introduced its ProScope Micro Mobile – it’s a lab-quality microscope that mounts on the user’s iPhone.

New microscopy technique lets scientists see live viruses in their natural habitat

By - December 30, 2012 1 Picture
Traditionally, in order to view tiny biological structures such as viruses, they must first be removed from their natural habitats and frozen. While this certainly keeps them still for the microscope, it greatly limits what we can learn about them – it’s comparable to an ichthyologist only being able to study dead fish in a lab, instead of observing live ones in the ocean. Now, however, researchers at the Virginia Tech Carilion Research Institute have devised a technique for observing live viruses in a liquid environment. It could have huge implications for the development of treatments for viral infections. Read More

X-ray microscope delivers unparalleled nanoscale images in 3D

By - May 6, 2012 2 Pictures
A new X-ray microscope at Brookhaven National Laboratory is being used to create unparalleled high-resolution 3D images of the inner structure of materials. Using techniques similar to taking a very small-scale medical CAT (computer-assisted tomography) scan, the full field transmission x-ray microscope (TXM) enables scientists to directly observe structures spanning 25 nanometers - three thousand times smaller than a red blood cell - by splicing together thousands of images into a single 3D X-ray image with "greater speed and precision than ever before." This capability is expected to power rapid advances in many fields, including energy research, environmental sciences, biology, and national defense. Read More
