Watching Bacteria Evolve, With Predictable Results

If we could somehow rewind the history of life to the dawn of the animal kingdom, it would be unlikely that we humans would ever evolve, the evolutionary biologist Stephen Jay Gould argued. The history of life was shaped by too many flukes and contingencies to repeat its course.

Scientists ca... Read More

Virus-derived particles target blood cancer

Ottawa researchers have developed unique virus-derived particles that can kill human blood cancer cells in the laboratory and eradicate the disease in mice with few side effects. The study is published in Blood Cancer Journal by co-senior authors Drs. David Conrad and John Bell of the Ottawa Hos... Read More

How To Rid The Developing World Of Deadly Bacteria? Steam

By making water boil at much lower temperatures, scientists are using steam generated by the sun as a way sanitize things in places where unclean conditions often lead to disease and death.

Up to 2.5 billion people lack access to proper sanitation. They use "flying toilets" to dispose of excr... Read More

The microscopic world of corals [video]

Here's an amazing video from PBS Digital Studios' “Under H2O” series, with micro images of corals.

Corals are beautiful when seen through your own eyes in sunlight, but for scientists at the University of Hawaii, seeing corals in this manner is not enough. They are using a revolutionary new t... Read More

Even Bacteria Use Social Networks

The next time your Facebook stream is filled with cat videos, think about Myxococcus xanthus. The single-cell soil bacterium also uses a social network. But forget silly distractions. M. xanthus relies on its connections to avoid getting eaten and to score its next meal.

That’s the latest ins... Read More

MWV Episode 73 - Shutting Down the Government: Yellow Fever and Anthrax

How can something too small to be seen with the naked eye be powerful enough to bring down something like the U.S. Government? It turns out that microbes, mostly invisible, have the extraordinary capacity to affect our lives – through outbreaks of disease and the spread of fear. Twice in hist... Read More

Green Alga Found to Prey on Bacteria, Bolstering Endosymbiotic Theory

A green alga with throat- and stomach-like structures can swallow and digest bacteria when deprived of light, further bolstering Lynn Margulis’s widely accepted idea that the origin of the plant-powering chloroplast was a fortuitous bout of indigestion.

Termed “Endosymbiotic Theory“, the idea... Read More

The Microbes We're Made Of (video)

The human body hosts more than ten thousand different kinds of microbes. Most of these bacteria aren't harmful - in fact, many of them actually aid the immune system. From the Smithsonian Channel.
