Researchers as the University of Massachusetts are working with Geobacter by manipulating their genetic material. This manipulation makes the bacteria produce filaments of tryptophan, increasing the electrical conductivity of the bacteria by 2,000 times.
The uses for these nanowires could be... Read More
Have you ever gone to the beach, ready for a day of sun and sand, only to find a warning sign? One of the most common reasons beaches close is due to the presence of coliform bacteria. These indicator bacteria, such as Escherichia coli, are used as markers for fecal waste, since their presence c... Read More
Copper is used in everything from automobiles to air conditioners, but it has one property that makes it especially attractive for medical uses: It kills bacteria.
A burgeoning opportunity for copper producers relies on a simple premise: that the base metal is good for your health.
Copper ... Read More
No matter the niche field a scientist pursues, there is one aspect of almost all career paths that scientists have in common: teaching. Whether lecturing a quorum of undergraduates about bacterial genetics, mentoring a research fellow as they learn the lab protocols, or presenting an invited lec... Read More
With drug-resistant bacteria on the rise, scientists believe the nose is engaging in "microbial warfare". Scientists in Germany have identified that Staphylococcus lugdunensis, found in the nose, excretes a compound they named lugdunin. This compound prevents S. aureus from growing. S. aureus ca...

Boston’s T, the United States' fourth busiest mass transit system, sees 569,200 passengers on any given workday. Since each of those people has a... Read More
The Gram-positive bacterium Enterococcus faecium is a member of the ESKAPE pathogens for which drug resistance has been a growing problem. How E. faecium becomes drug resistant has been a long-standing question, and is the focus of a new study now available in Antimicrobial Agents and Chemothera... Read More
That is the amount of money the U.S. spent over a 10-year period from 2004 through 2013 promoting abstinence before marriage as a way of preventing HIV in 14 countries in sub-Saharan Africa. Unfortunately, according to the most comprehensive independent study conducted to date of the effort, the... Read More
Health officials have warned pregnant women to avoid travel to the more than 45 countries and territories in which the Zika virus is circulating. Infection during pregnancy can lead to birth defects in infants, particularly brain damage and abnormally small heads, called microcephaly.
But wit... Read More
A surprisingly specific genetic portrait of the ancestor of all living things has been generated by scientists who say that the likeness sheds considerable light on the mystery of how life first emerged on Earth.
This venerable ancestor was a single-cell, bacterium-like organism. But it has a... Read More
The Zika epidemic could be over in three years – but by then up to 93.4 million people may have been infected, including 1.65 million women of childbearing age, and tens of thousands of babies could be affected. But even if the epidemic fizzles out, this could be a temporary relief: a decade lat... Read More
Using novel computational and biochemical approaches, scientists have accurately designed and built from scratch 10 large protein icosahedra -- polyhedra with 20 faces -- similar to viral capsids that carry viral DNA. The designed structures are made of two different engineered proteins, present... Read More
Transmission of Zika virus (ZIKV) was first detected in Colombia in September 2015. As of April 2016, Colombia had reported over 65,000 cases of Zika virus disease (ZVD). We analysed daily surveillance data of ZVD cases reported to the health authorities of San Andres and Girardot, Colombia, bet... Read More
This June Disney released the anticipated Pixar Animation Studios sequel Finding Dory to earn the largest animated film opening receipts in North America ever. The popularity of the original Finding Nemo in 2003 led to reportedly increased demand for clownfish like Nemo for pets; some conce... Read More
Painting with glowing bacteria. What better way to get students anyone excited about microorganisms? Dr. Mark O. Martin, a self-proclaimed “Microbial Supremacist” uses glowing bacteria to entice students to explore the mysteries of microbiology. Now fellow microbiology educators at ASMCUE creat... Read More
Well you may ask what virus ?
