The microscope is a staple of the scientific community, allowing researchers to study what’s too small to be seen by the naked eye. But how exactly did it rise to such notoriety?

This looks like a bizarrely-colored aerial image of a city at night, but in reality it’s something much smaller, and much more fascinating: the tiny scaffolding and organelles that make up a single human cell. Harvard researchers caught this view using a new technique powered by light-up strands of custom-built DNA.

This monochrome image of living tissue has some extremely unwelcome visitors lurking within it. Taken from some of the first ever 3D images of HIV at work, those little blue circles show the virus infecting the surrounding cells.

When it comes to imaging microscopic objects, you have to make a decision: do you want high resolution images of stationary objects, or coarse images of moving ones? Fortunately, X-ray holography means that may not be the case much longer.

Who needs Christmas lights when you have glowing mammalian cells? This wreath, assembled from cells with proteins and structured stained different colors, was made by Dr. Donna Beer Stolz at the University of Pittsburgh. It won 19th place in the 2011 Nikon Photomicrography Competition—but top honors for holiday cheer. [Nikon]

Microscopes are a dime a dozen in universities, so there’s plenty of fun to be had hacking ’em any way you can—like a team of researchers from Caltech, who have developed a cheap and easy way to increase their resolution by a factor of 100.

A team of researchers at the California Institute of Technology, led by Professor Changhuei Yang, have figured out a way to crank their microscopy up to 11. Usually, scientists are forced between a rock and a hard place: they can have high res images of small areas or low resolution pictures of larger fields. Using a strategy known as Fourier ptychographic microscopy, Yang’s team was able to computationally correct a standard microscope’s low res imagery, producing a billion-pixel picture. By adding an LED array to an existing microscope — the only hardware tweak their $200 system calls for — the researchers were able to stitch together a 20X quality image from a 2X optical lens. The information gleaned from the LED lights was corrected entirely on a computer, making it an exceptionally cost effective way to create high res microscopic images. The team’s report, published by the journal Nature Phototonics, can be read in full at the source link below.

This may look like your last bad trip, but in fact you’re looking at a sample of damaged blood cells which is over 5,000 years old.
