A new survey published by the Pew Research Center for the People & the Press and the American Association for the Advancement of Science checks the pulse of how scientists and the public view the field of science. For example:
17% of the public thinks that U.S. scientific achievements rate a... Read More
Scientists at Albert Einstein College of Medicine of Yeshiva University have devised a laboratory test for predicting whether microbicides against HIV are safe for human use. The researchers have also discovered why several supposedly "safe" microbicides made women more susceptible to HIV infect... Read More
This recent paper prevents evidence that microbes (Escherichia coli and Saccharomyces cerevisiae) can evolve to anticipate environmental change. They show that pre-exposure to a stimulus that usually occurs before a second stimulus (i.e. lactose before maltose in E. coli) will improve the abilit... Read More
German and Slovakian researchers are attempting to solve two problems at once, the volatile market for grain waste and the growing demand for biofuel.
Not to long ago beer manufacturers in Europe simply sold their waste to farmers who either fed it to their animals or used it as fertilizer, "... Read More
Merry Youle from From the Small Things Considered Blog points readers to an article by Hans-Dieter Görtz on the fascinating relationships between ciliates and bacteria.
"Organisms such as ciliates that dine daily on bacteria run the risk of getting an infection. Indeed, ciliates—large, comple... Read More
DOE JGI Genome Biology head Nikos Kyrpides believes that science as a whole would benefit from the introduction of common standards for genomic data collection and analysis. In fact, he believes the lack of shared standards is currently hurting research, compromising data during critical procedu... Read More
In an article in the journal Cell, researchers discussed how they recently identified one mechanism used by mycobacterium tuberculosis to resist the immune system. Apparently TB can remain latent in someone's system for decades, resisting mutagens produced by the macrophage where it lives. Tough... Read More
'Late blight,' which actually appears early in the tomato growing season, is expected to hit hard this year. The fungal infection is actually the same on that destroyed entire potato crops in Ireland during the 1840's, and our cool, wet, cloudy spring is expected to create a particularly nasty o...

An interesting example of how resiliant bacteria can be; a strain of Listeria has taken root at a Williamsburg cheese factory. In 2004 inspectors collected a test sample of bacteria that turns out ot be the same strain as that just collected. Basically, despite disinfection attempts, a strain es... Read More
In local news for MicrobeWorld, Vibrio infections in the Chesapeake Bay area are on the rise and several groups think this is the EPA's fault for not cleaning up the Bay properly. Read More
Apparently humans can transmit the pandemic strain A/H1N1 on to pigs. Early in the scare, we were worried that humans could catch the virus from pigs, but apparently a human-to-pig scenario is far more likely. Does anyone else thing that we owe pigs an apology (Especially Egypt)? Read More

"Professor Lewis Wolpert and Dr Rupert Sheldrake, have set up a wager on the predictive value of the genome. Professor Wolpert believes that all biological phenomena can in principle be explained in terms of DNA, proteins and other molecules, together with their interactions. He is convinced tha...

Dr. Paul Keim, famous for identifying the anthrax strain during the anthrax letter attacks back in 2001, is featured in this video about the importance of rapid detection of disease through DNA sequencing.
Dr. Keim was also a guest on Meet The Scientist featured here at MicrobeWorld. Listen ... Read More
Obesity is definitely an epidemic in our society, even around the world. Scientists at The Forsyth Institute have discovered a link between certain oral bacteria and obesity. I can't imagine that it's the entire explanation for overweight people, but there could definitely be some causality. Wha... Read More

"Self-assembling and self-organizing systems are the Holy Grails of nanotechnology, but nature has been producing such systems for millions of years. A team of scientists has taken a unique look at how thousands of bacterial membrane proteins are able to assemble into clusters that direct cell m... Read More
