This colorized negative stained transmission electron micrograph (TEM), captured by F.A. Murphy in 1968, depicts a Marburg virus virion, which had been grown in an environment of tissue culture cells. Marburg hemorrhagic fever is a rare, severe type of hemorrhagic fever which affects both humans... Read More

It was an amazing visit that will be fully documented in an... Read More
Möbius strips are special loops that only have one continuous side. Now we've built the smallest Möbius strips ever - out of DNA. Here you can see the nanometer-sized DNA loops, folded like origami.
The ability to create complex structures on the tiniest of scales is one of the great challeng... Read More
Confocal micrograph showing Shigella bacteria (pink) invading the intestinal lining. The bacteria infects the cells by high-jacking the cell's internal actin skeleton (green) to facilitate its entry into the cell and spread into adjoining cells, using polymerizing actin comet tails as several ca...
