Modern archeologists, excavating ancient Egyptian tombs, have often found something unexpected amongst the tombs’ artifacts: pots of honey, thousands of years old, and yet still preserved. Through millennia, the archeologists discover, the food remains unspoiled, an unmistakable testament to the... Read More
Spot the next plague before it arrives. Predict the next swine flu outbreak before it makes headlines. Even detect a biological weapon before it's launched.
These are the goals of an ambitious initiative, launched Thursday, to build a worldwide surveillance system for infectious diseases.

Wine grapes present a unique biogeography model, wherein microbial biodiversity patterns across viticultural zones not only answer questions of dispersal and community maintenance, they are also an inherent component of the quality, consumer acceptance, and economic appreciation of a culturally ...

The American Museum of Natural History has began recruiting for this new, free, spring, after school program for high school students. Please help them out by sharing the word with interested teens:
Did you know that the Twa, a group of people in the Congo, rarely get cavities or that Japanes... Read More
This episode: Bacteria are able to incorporate DNA from the environment into their genomes, even if it's thousands of years old!

Quorum sensing is one of the most amazing things about bacteria. More and more research is focusing on potential quorum sensing applications in biomedicine and many other fields of life sciences.
This is a video that I made about QS for a competition in my University. No previous science bac... Read More
Where humans travel, bacteria will follow. If people are in space for any amount of time, bacteria are sure to thrive there so it’s good to know that there are already researchers looking at how the environment within spaceships affects bacterial populations. Work done on planktonic colonies of ... Read More
A new study published in the journal Nature provides the most comprehensive analysis to date of the evolutionary relationships of influenza virus across different host species over time. In addition to dissecting how the virus evolves at different rates in different host species, the study chall... Read More
The environment significantly influences whether or not a certain bacterium will block mosquitoes from transmitting malaria, according to researchers at Penn State.
The researchers used a species of malaria parasite that affects rodents, Plasmodium yoelii, and the mosquito, Anopheles stephens... Read More
To enter into symbiosis with nitrogen-fixing bacteria, host plants reprogram their root cells. An LMU team has now identified a calcium-binding protein complex that can be persuaded to spontaneously induce the formation of root nodules.
In almost all ecosystems, plant growth rates are limited... Read More
In his second expedition to South America, Darwin discovered many new species of animals and plants. The field observations obtained throughout this 5-year expedition provided the intellectual framework for the maturation of his ideas on evolution. It also introduced the world to a tiny (2-3 cm ...

The rise of drug-resistant bacteria and other biological threats has pushed the Pentagon to seek help developing small molecules that can stop some of the world's most dangerous pathogens.
The Defense Threat Reduction Agency, which seeks ways to stop or limit the effects of weapons of mass de... Read More
After 26 years of workdays spent watching bacteria multiply, Richard Lenski has learned a thing or two.
He's learned that naturalist Charles Darwin was wrong about some things. For one, evolution doesn't always occur in steps so slow and steady that changes can't be observed.
Lenski also lea... Read More
Public health officials issued a warning Thursday that thousands of Bay Area residents were potentially exposed to measles last week when a UC Berkeley student with the virus attended classes in Berkeley and rode on BART.
The student, a Contra Costa County resident whose name was not released... Read More
Four intracellular Toxoplasma gondii parasites are shown undergoing cellular division by an internal budding process known as endodyogeny. Staining with a T. gondii surface antigen provided heart-shaped images (shot on Valentine’s Day). The definitive host of these parasites is the cat, but they... Read More
In a first-of-its-kind study for Lyme disease, researchers have used live, disease-free ticks to see if Lyme disease bacteria can be detected in people who continue to experience symptoms such as fatigue or arthritis after completing antibiotic therapy. The technique, called xenodiagnosis, attem... Read More
Communication is vital to any successful relationship. Researchers from the Institute of Food Research and the University of East Anglia have discovered how the beneficial bacteria in our guts communicate with our own cells.
This is a key step in understanding how our bodies maintain a close ... Read More
When confronted with a new bacteria there are a series of simple tests that can be carried out to give a rough idea of the properties of the bacteria you are dealing with. One of the simplest and most useful tests is known as “Gram staining” which is a process of staining cells either purple or ... Read More
