We’ve seen mobile phone lens attachments and hacks that help you to take macro photos with your smartphone, but never before have we seen one that helps capture micro images.
It attaches to any smartphone or tablet via an adhesive backing and — using the slides provided in combination with a ... Read More
Scientists have for the first time come closer to understanding how a clone of E coli, described as the most important of its kind to cause human infections, has spread across the world in a very short time. E coli clone ST131 is one of the leading causes of urinary tract and blood stream infec... Read More
Three organisms inoculated onto blood agar, straight line inoculation, to demonstrate hemolysis. From top to bottom:
Streptococcus pyogenes: beta, complete lysis of red blood cells, clear area around colony growth.
Streptococcus bovis: alpha, incomplete lysis of red blood cells, green area ... Read More
Researchers at the Georgia Institute of Technology and the Joint BioEnergy Institute have engineered a bacterium to synthesize pinene, a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missiles and other aerospace applications. With improvements ... Read More
Q. When you eat yogurt or take a probiotic supplement, why aren’t the probiotic bacteria killed by stomach acids?
A. The point of consuming a probiotic supplement in a food like yogurt, a powder or a capsule is to introduce beneficial bacteria in the gut, said Dr. Christine Frissora, a gastro... Read More
Treating food products with select bacteriophages - viruses that target and kill bacteria - could significantly reduce concentrations of E. coli, a Purdue University study shows.
An injection of bacteriophages - also known informally as "phages" - nearly eradicated a toxin-producing strain of... Read More
The gut microbiota is responsible for many aspects of human health and nutrition, but most studies have focused on “western” populations. An international collaboration of researchers, including researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has for th... Read More
Some natural types of fungus appear to inhibit the build-up of tau—a protein linked to Alzheimer’s disease and other neurodegenerative diseases.
“Tau is a protein that is produced by the body,” says T. Chris Gamblin, associate professor of molecular biosciences at the University of Kansas. “I... Read More
(Reuters) - An Ebola outbreak blamed for 135 deaths in West Africa in the past month was not imported from Central Africa but caused by a new strain of the virus, a study in a U.S. medical journal said, raising the specter of further regional epidemics. The spread of Ebola from a remote corne... Read More
State legislators like to claim official symbols for nearly everything. There are state birds, state dinosaurs, even a state question (New Mexico's “Red or green?”). The South Arkansas Vine Ripe Pink Tomato is both Arkansas's official fruit and its vegetable. Nebraska’s official drink is water. ... Read More
HOUSTON – (April 16, 2014) – An international research team led by Cesar A. Arias, M.D., Ph.D., at The University of Texas Health Science Center at Houston (UTHealth) has identified a new superbug that caused a bloodstream infection in a Brazilian patient. The report appeared in the April 17 iss... Read More
An international study led by The University of Queensland has tracked a potentially devastating multi-drug resistant E. coli strain that is only one gene away from being resistant to almost all antibiotics.
UQ Australian Infectious Diseases Research Centre scientist Dr Nouri Ben Zakour said ... Read More
Our bones are remarkable feats of engineering; strong and yet light, shot through with holes and yet able to bear incredible loads. This super-strong natural material is built as cells incorporate hard minerals like calcium into living tissue. Now, scientists at the Massachusetts Institute of Te... Read More
Resistance to an entire class of antibiotics – aminoglycosides -- has the potential to spread to many types of bacteria, according to new biochemistry research. A mobile gene called NpmA was discovered in E. coli bacteria several years ago. Global spread of NpmA and related antibiotic resistance... Read More
Researchers at the Division of Nanotechnology and Functional Materials, Uppsala University have developed a paper filter, which can remove virus particles with an efficiency matching that of the best industrial virus filters. The paper filter consists of 100 percent high purity cellulose nanofib... Read More
When studying bacteria it is quite easy to get fascinated with them as a laboratory specimen while forgetting the huge impact they can have in real life societies. I find the PLoS journal of Neglected Tropical diseases redresses that as it covers work with bacteria and parasites from the front l... Read More
Microbiologists from Trinity College Dublin have discovered that an identical protein is used differently by two species of bacteria to help them cope with distinct types of environmental stress. The discovery reveals an extraordinary level of versatility in the way different genes are ‘switched... Read More
Effect of founder cell density on the spatial pattern formation in colony biofilms.
The colony biofilms were obtained by following the protocol described in van Gestel et al (2014) ISME Journal (doi: 10.1038/ismej.2014.52). Briefly, GFP and mKATE2 labeled Bacillus subtilis strain were mixed in ... Read More
In the spring of each year I teach a virology course to undergraduates and masters students at Columbia University. I produce video recordings of all my lectures not only for students in the course, but for anyone else who is interested in learning about viruses.
You can find my virology lect... Read More
NASA Public Affairs Officer Dan Huot talks with Dr. David Coil about Project MERCCURI, which will study a "crowdsourced" collection of microbial samples scheduled to launch to the International Space Station aboard the SpaceX-3 mission.
