In the swimming motions of aerobic bacteria against asymmetric gears, apparent randomness can yield directed motion. The collective random motion of tiny bacteria can be harnessed to turn much larger mechanical gears in a preestablished direction, a new study demonstrates. The research, set to b... Read More
There is some evidence that viruses are involved in colony collapse disorder, a phenomenon in which worker bees disappear. This condition is receiving a great deal of attention ranging from basic scientific research (summarized on TWiV 46) to a PBS episode to a documentary entitled 'Colony' whic... Read More
You may know Wisconsin's state animal (the badger), the state bird (the robin), or even the state dance (the polka). Now Wisconsin lawmakers want to name an official state microbe.

A team led by Yale University researchers has used nanosensors to measure cancer biomarkers in whole blood for the first time. Their findings, which appear December 13 in the advanced online publication of Nature Nanotechnology, could dramatically simplify the way physicians test for biomarkers ... Read More
Governments have been stockpiling the antiviral drug oseltamivir as a defence against pandemic flu. Now the medical journal BMJ has claimed there is insufficient evidence that the drug prevents serious complications of flu to warrant the policy. In a series of articles, it says the Swiss pharmac...

A vital gene that defends us against cancer has been found in one of the simplest of animals – a flat, amoeba-like creature called a placozoan. The discovery shows that p53, sometimes described as the "guardian of the genome", has been around for over 1 billion years.
The Placozoa are among t... Read More

What's gotten into you? In this hour we explore nature's moochers - the good, the bad, and the hideous. We have stories of lethargic farmers, zombie cockroaches, and even mind-controlled humans (kinda, maybe). Could parasites be the shadowy hands that pull the strings of life?

Bacteria use all sorts of cunning to trick hosts into doing their bidding. One con in their bag of tricks: the molecular mimic. In this ruse, bacteria or their agents look for all purposes like some native molecule in a cell, but then do not behave accordingly. Working with H. pylori, the bacter... Read More
