Wired magazine has put together an 8-part image gallery that matches the extremophile microbe with it's environment.

"Once upon a time, scientists routinely found life in places where it wasn’t supposed to exist. That doesn’t happen anymore, and not because the pace of discovery has s... Read More

Mmmmm, kinda looks like couscous right?
Well, though it might resemble a tasty side dish that's beloved in the Maghreb, it's actually a gnarly bacteria that causes URI's (upper respiratory infections) in both humans & animals.
Humans can prevent it by refraining from drinking unpasteurized mil... Read More

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are caused primarily by a single strain—USA300—of an evolving bacterium that has spread with “extraordinary transmissibility” throughout the United States during the past five years, according to a new study le...

Nature has just published a news special on microscopes and microscopy. Most of the associated articles are pay-per-view but the slideshow of images is free to check out. Click the source link above. Read More

Under a magnification of 200x, and using a lactophenol cotton blue mount fixation technique, this photomicrograph reveals some of the ultrastructural morphology exhibited by a Mucor sp. fungal organism. This image depicts two sporangia, a mature structure, which had ruptured, releasing its conte... Read More

This negative stained transmission electron micrograph (TEM) shows recreated 1918 influenza virions that were collected from supernatants of 1918-infected Madin-Darby Canine Kidney (MDCK) cells cultures 18 hours after infection.

To separate these virions, the MDCK cells are spun down (centrif... Read More

This pair of confocal micrographs demonstrates how a disease-causing strain of E. coli bacteria brings about diarrhoea by breaking down the waterproof barriers between the cells. The bacteria are seen as small red dots attached to the surface of intestinal cells making tiny pedestals out of one ... Read More

At a magnification of 1125X, this photomicrograph revealed some of the ultrastructural morphology exhibited by a Histoplasma capsulatum fungal macroconidium. The reproductive spores produced by H. capsulatum can be either macroconidia or microconidia. It is the macroconidia that exhibits finger-... Read More

This transmission electron micrograph (TEM) revealed the ultrastructural appearance of a number of virus particles, or “virions”, of a hantavirus known as the Sin Nombre virus (SNV).

In November 1993, the specific hantavirus that caused the Four Corners outbreak was isolated. Using tissue fro... Read More
