Infectious diseases like AIDS and hepatitis are never pretty. But the pathogens that cause many potentially deadly infections turn out to be absolutely beautiful when viewed under powerful microscopes.
"Nowadays scientists use X-ray crystallography and more recently by cryo-electron microscopy with 3D reconstruction," Dr. Jean-Yves Sgro, a senior scientist at the University of Wisconsin and an expert on imaging pathogens. "In many cases that means we have an atomic resolution of the virus" that spotlights the pathogens' amazing structure:
Hepatitis C Virus
Swine Flu Virus
Human Immunodeficiency Virus
West Nile Virus
Yellow Fever Virus
THESE slimy creatures may look like aliens from another planet but they are actually the life teeming inside a SINGLE drop of pond water. The colourful organisms - which also thrive in puddles - were captured using high-definition microscopy. The 'pond safari' pictures show everything from a paramecium moving through bacteria to a hydra 'defecating'. They were filmed by Peter Matulavich from Ohio, USA.
