In the world of microorganisms, microbes compete for turf, spew chemicals at foes, and sometimes exploit the microscopic ...

Pseudomonas aeruginosa (small rod-shaped bacteria) swarms toward and around a neighboring Cryptococcus neoformans (round yeast) colony. The thin fluid halo surrounding the yeast enables the bacteria ...

Described in The Optical Society (OSA) journal, Optics Express, the new approach involves bouncing laser light off individual bacteria under the microscope, creating holographic images of them ...

Under the leadership of Prof ... with which they can identify individual bacteria and simultaneously determine which metabolites are present in the cells -- all without cultivating the bacteria ...

Imaging non-adherent cells by super-resolution ... DNA in individual bacterial cells. Here we show that it is possible to overcome these limitations in optical nanoscopy by the combined use ...

Biophysicists have revealed that fast-swimming, sulfur-eating microbes known as Thiovulum majus can organize themselves into a two-dimensional lattice composed of rotating cells, the first known ...

Gram staining is one way scientists can identify bacteria. Gram-positive bacteria, such as Staphylococcus, appear blue or purple under a microscope when scientists apply a stain. Conversely, Gram ...

The monitoring is performed with a basic optical microscope, a video camera or a mobile phone. The ONMD technique monitors the microscopic oscillations of bacterial cells (nanomotion) that ...

The optical microscope relies on light and consists ... Optical microscopes are used to examine living organisms (such as bacteria, yeasts, and single-celled organisms) or fixed samples (like ...
