GERMS: Microscope Germs

microscope germs

In a recent study published in the Proceedings of the National Academy of Sciences, scientists used a powerful microscope to observe small molecular machines that bacteria use to infect host cells. This new finding is vital for the development of anti A cheap holographic microscope capable of detecting E. coli and other bacteria has been developed by researchers in the US. The handheld device uses a laser instead of lenses to identify bugs in water, food or blood, and costs less than $100 (£60) to build. As you take steps to avoid the germs and viruses that proliferate as winter progresses, you've no doubt received a good share of advice on how to avoid catching whatever's going around. ABCNews OnCall+ spoke with experts about some of the popular myths BERKELEY, Calif., March 2 (UPI) --Over the last two decades, scientists have gone back and forth on whether or not ultra-small bacteria exist. But now, for the first time, there's photographic proof. Researchers at Department of Energy's Lawrence Berkeley Bacteria is one of the last things anyone hopes to be acquainted with intimately. However, taken with a powerful electron microscope, the following photos offer an appealing glimpse into the off-putting world of bacteria — some of which, at one point a nanoscientist and professor in the LSU Department of Biological Sciences who is researching ways to kill bacteria on a nanoscale.

Bacteria that cause a range of diseases from dysentery to plague use a needlelike ''sword" to attack cells, and some have evolved a shield to protect it from the immune system, several teams of researchers reported in Friday's issue of the journal Science. Researchers at UCLA have built a cheap, optics-free holographic microscope capable of detecting bacteria like E. coli in things like water, food, and blood. And by cheap, we mean really cheap. The researchers say it costs less than $100 to build. They may look like rare plants, or perhaps the surface of a far off planet but these gruesome 'alien invaders' are in fact the plaque that coats your teeth, providing a stark reminder of the consequences of poor dental hygiene. Enough to make anyone book Under the microscope, the bacteria displayed densely packed spiral the study authors say. "These newly described ultra-small bacteria are an example of a subset of the microbial life on earth that we know almost nothing about," says Jill Banfield .
