Microbiologists have known for some time that different diets produce different gut flora, but new research indicates that the changes take hold with startling quickness. Bacterial populations shift measurably in the first few days following a big shift in what we eat, according to a recent stud... Read More
Vaccines are just for kids, right? Not any more. U.S. health officials now recommend at least a half dozen vaccines for adults, to prevent pneumococcus virus, hepatitis, shingles and other ailments. And although the portion of adults who get these vaccinations rises slightly each year, the rates... Read More
Fernan Federici’s microscopic images of plants, bacteria, and crystals are a classic example of finding art in unexpected places.
A couple years ago, Federici was working on his Ph.D. in biological sciences at Cambridge University studying self-organization, the process by which things organi... Read More
(upwave.com) -- Even if you're one of the many people who believe that exposing yourself to day-to-day germs is healthy for your immune system, it's still wise to take steps to protect yourself from the most infectious germs in your home. "Bugs like Escherichia coli (E.coli), salmonella and camp... Read More
Some may think of turkeys as good for just lunch meat and holiday meals, but bioengineers at UC Berkeley saw inspiration in the big birds for a new type of biosensor that changes color when exposed to chemical vapors. This feature makes the sensors valuable detectors of toxins or airborne pathog... Read More
Transplanting fecal matter has been one of the best remedies at treating a tough bacterial infection known as Clostridium difficile (C. diff). Scientists are now saying they can give all the benefits of poop in a tiny pill.
This new pill method is a less yucky way to do "fecal transplants." A... Read More
Researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI), a multi-institutional partnership led by Berkeley Lab, have identified the genetic origins of a microbial resistance to ionic liquids and successfully introduced this resistance into a strain of E. coli bact...

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
Two studies published in the December issue of Infection Control and Hospital Epidemiology show antibiotic resistance patterns for children have held stable over a seven-year period and surgical patients in U.S. children's hospitals account for 43 percent of all antibiotic use in children's hosp...

The hemagglutinin (HA) and neuraminidase (NA) glycoproteins of the influenza virus particle serve distinct functions during infection. The HA binds sialic acid-containing cellular receptors and mediates fusion of the viral and cell membranes, while the NA removes sialic acids from glycoproteins.... Read More
On a recent morning, Noah Fierer, a professor of ecology and evolutionary biology at the University of Colorado, Boulder, found himself standing 1,000 feet above the farmland of eastern Colorado. He was perched near the pinnacle of the Boulder Atmospheric Observatory, a cellphone-tower-like spir... Read More
Genomic analysis of transplant patients finds an opportunistic microorganism whose elevated presence could be used an indicator in treatment.
More than 260,000 Americans are alive today thanks to transplant operations that have replaced their failing kidneys, hearts, lungs or livers with hea... Read More
Officially called a fecal microbiota transplantation, or FMT, the procedure involves the insertion of a small, diluted sample of stool from a donor into the colon of a recipient. (Clearly disgusting.) The swap imports a healthy community of bacteria, the intestinal microbiota, into the system of... Read More
We're used to relying on antibiotics to cure bacterial infections. But there are now strains of bacteria that are resistant to even the strongest antibiotics, and are causing deadly infections. According to the CDC, "more than 2 million people in the United States every year get infected with a ... Read More
Harvard stem cells scientists at Brigham and Women’s Hospital and MIT can now engineer cells that are more easily controlled following transplantation, potentially making cell therapies, hundreds of which are currently in clinical trials across the United States, more functional and efficient.

JOHANNESBURG, 2 April 2014 (IRIN) - Outbreaks of a deadly fungal disease in wheat crops in Germany and Ethiopia in 2013 have had the scientific community buzzing over the threat posed to global food security. Wheat stem rust, also known as wheat black rust, is often referred to as the “polio of... Read More
Reporting in the Proceedings of the National Academy of Sciences, researchers were able to fix "misfolded" proteins and restore their function in mice. Lead researcher Michael Conn discusses how to mend an incorrectly folded protein and what this may mean for developing future therapies for a va... Read More
We continue our semi-annual ritual and post this quick tour of our blog posts published since December, 2012.
Our new section dealing with “pictures that made a difference but may be nearly forgotten by now” seems to be off to a good start. Please send us suggestions of... Read More
With increasing attention toward generating cost-effective biochemical conversion methods for producing biofuels, it helps to follow the leaders who have perfected the process. The mere Reticulitermes flavipes, or eastern subterranean termite, a famous feaster of lignocellulosic plant materials ... Read More
Not all viruses are bad for us. Some of them might even help up us fight off bacterial infections someday.
Naturally occurring viruses called bacteriophages attack specific types of bacteria. So researchers at the University of Leicester decided to try and take advantage of phages' bacteria-d... Read More
