Scientists have deciphered the 3-D structure of a protein that confers antibiotic resistance from one of the most worrisome disease agents: a strain of bacteria called methicillin-resistant Staphylococcus aureus (MRSA), which can cause skin and other infections. The team's findings may be an imp... Read More
Scientists at The Scripps Research Institute (TSRI) have invented a new method for designing artificial proteins, and have used it to make key ingredients for a candidate vaccine against a dangerous virus, respiratory syncytial virus (RSV), a significant cause of infant mortality. The virus has ... Read More
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
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
The science behind the transformation from plants to milk to cheese is amazing. In fact, cheese has much in common with wine and beer: They result from fermentation by microorganisms; they are “value-added” products where processing greatly increases the value; and they reflect local climate and...

This is an accurate visualization of the Bacteriophage T4 based on Cryo-EM datasets of the virus. The scope of the animation is to show the infection process of the T4 into an E. coli cell. All scientific data sets and motion based off of research from Michael Rossmann Laboratory (Purdue Univers... Read More
The death of a woman in China from a strain of bird flu previously unknown in humans is a reminder of the ever-present potential pandemic threat from mutating animal viruses, scientists said on Wednesday.
The new strain, called H10N8, has so far infected only two people - a fatal case in a 73... Read More
Tularemia is endemic in the northeastern United States, and is considered to be a risk to biosecurity -- much like anthrax or smallpox -- because it has already been weaponized in various regions of the world.
At the 58th Annual Biophysical Society Meeting, which started Saturday and continue... Read More
In the mid-2000s, scientists identified two novel antimicrobial compounds in the bacterium Streptomyces platensis, each of which target a different enzyme involved in fatty acid synthesis in other microbes. Platensimycin and platencin are now being explored as a new class of antibiotics. Researc... Read More
Anna Dumitriu combines bacteria and textile design to explore our relationship with microorganisms.
Walk into Watermans, a theatre and arts exhibition space in West London, and you'll come across a series of intriguing installations: early 20th century medical artifacts, a dress colored with ... Read More
Lyme disease is often evident by a rash on the skin, but infections do not always produce similar rashes. This can make it difficult to detect the disease early, when antibiotic treatment is most effective. Researchers describe a new mathematical model that captures the interactions between dise...

Recently a number of children in California have developed a poliomyelitis-like paralysis. The cause of this paralysis is not yet known, and information about the outbreak is scarce. However, acute-flaccid paralysis is not uncommon (California would be expected to report about 75 cases a year, b... Read More
Invasive species aren’t just species—they can also be pathogens. Such is the case with the West Nile virus. A mosquito-borne virus identified in the West Nile subregion in Uganda in 1937—hence the name—West Nile wasn’t much of a concern to people elsewhere until it broke out of Africa in 1999. T...

The study confirms "the existence of an offensive biological warfare research programme in Nazi Germany." In January of 1942, Heinrich Himmler ordered the opening of an entomological laboratory in the Dachau concentration camp in southeastern Germany. But why? The stated purpose of the institut...

A new study that analyzed about 80,000 gene sequences from flu viruses has revealed that birds may have had some help from horses in spreading the virus that eventually killed 50 million to 100 million people in the influenza pandemic in 1918. Two viral genes may have circulated for years before... Read More
Under favorable conditions, the microbe, a species of yeast called S. pombe, does not age the way other microbes do, the researchers said. Typically, when single-celled organisms divide in half, one half acquires the majority of older, often damaged cell material, while the other half acquires m... Read More
The coronavirus responsible for Middle East Respiratory Syndrome (MERS) is prevalent in camels throughout Saudi Arabia and has been around for at least 20 years, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology.
“Our study ... Read More
This transmission EM of a thin section of a T2 phage infecting an E. coli cell was produced by Lee Simon in the late 1960’s. It is noteworthy for depicting a remarkably large number of properties of the phage and of the infection process. Can you figure out how many such characteristics are illu... Read More
Although the bursts of rainbow colors in this photograph are mesmerizing, microbes fight for their lives in the background. Chemist Michael P. Zach of the University of Wisconsin-Stevens Point, snapped this image of a salt sample he collected in a hot, arid valley near Death Valley National Park... Read More
