Scientific American placed Professor Eshel Ben-Jacob and Dr. Itay Baruchi's creation of a type of organic memory chip on its list of the year's 50 most significant scientific discoveries in 2007. For the last decade, he has pioneered the field of Systems ... Read More
This video describes the role of microbes in the production side of the global food web. Microbes transform essentially inert gaseous nitrogen into active nitrogen compounds, which then go on to make amino acids and proteins. Read More
Here's a great video published by Science News which shows a newborn bacterial cell stand up, walk away from its sister cell, and then detache from the surface. Credit: Courtesy of Gerard Wong, University of California, Los Angeles, Bioengineering, California NanoSystems Institute.

In 2002, bearing her microscope on a microbe that lives in the gut of fish, Bonnie Bassler isolated an elusive molecule called AI-2, which showed not only that almost all bacteria can communicate -- but that they do so all the time. (Watch her 2009 TEDTalk!) The TED Blog interviewed Bassler ... Read More
The swine flu virus that caused a 2009 pandemic has been found in elephant seals off the central California coast, according to new research. The study, published in the journal PLoS ONE, is the first report of the virus H1N1 in any marine mammal. Researchers are now being advised to wear protec... Read More
This episode describes how the bane of sausage makers and home canners became the darling of the Hollywood set. The lethal toxin made by our friend Clostridium botulinum was put to good use paralyzing facial muscles and erasing frown lines. This video has an amazing intro sequence. Read More
Critically ill patients with the pandemic H1N1 influenza who received triple the standard dose of the influenza drug oseltamivir were 7 times more likely to completely clear the virus from their system in 5 days than those who received the standard dose. This discussion addresses the healthcare... Read More
Ralph is a non-dual, spiritual alchemist and social activist. He is bridging many worlds: the business with the ethical, the psychological with the spiritual, the Chinese Zen tradition with Sufism and Yoga.

This episode explains how microbiologists perfected the art of using the fewest possible letters in place of really long complicated words, long before cell phones and the internet were invented! Read More
Anti-malarial drugs are being used inappropriately for sick children in Zambia -- a problem that can be addressed by arming community health workers with a simple rapid-diagnostic test and a supply of antibiotics, a study led by researchers at Boston University School of Public Health has found....

MIT researchers find a way to boost lithium-air battery performance, with the help of modified viruses.
Lithium-air batteries have become a hot research area in recent years: They hold the promise of drastically increasing power per battery weight, which could lead, for example, to electric c... Read More
How can antibiotics be better used? How can the development of resistance to antibiotics be avoided? What are the consequences of their ill-considered usage for humans and also for animals? These were some of the topics that the organizers of ICPIC 2013, the International Conference on Preventio... Read More
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 cyanobacterium Synechocystis produces toxins that often lead to its own demise. The biologists Stefan Kopfmann and Prof. Dr. Wolfgang Hess from the University of Freiburg have determined the logic governing this mechanism. The cyanobacterium Synechocystis produces several toxins. However, mo... Read More

Two teams have now clai... Read More
The next time you look in a mirror, think about this: In many ways you're more microbe than human. There are 10 times more cells from microorganisms like bacteria and fungi in and on our bodies than there are human cells.
Scientists increasingly think that these microorganisms have a huge inf... Read More
it is not a nice way to die. As the virus spreads through your lungs, your immune system goes into overdrive. Your lungs become leaky and fill with fluid. Your lips and nails, then your skin, turn blue as you struggle to get enough oxygen. Basically, you drown.
Flu can kill in other ways, too... Read More
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
