Metagenomics has allowed researchers to reconstruct the genome sequence of a deadly Shiga-toxigenic E. coli outbreak without having to grow bacteria in the lab.
“The outbreak of Shiga-toxigenic Escherichia coli illustrated the effects of a bacterial epidemic on a wealthy, modern, industrializ... Read More
This digitally-colorized scanning electron micrograph (SEM) depicted the dorsal (upper) surface of a Giardia protozoan that had been isolated from a rat’s intestine. Some of the identifying morphologic characteristics include pairs of thread-like flagella that facilitate motility, and a ventolat... Read More
In the search for new antibiotics, researchers are taking an unusual approach: They are developing peptides, short chains of protein building blocks that effectively inhibit a key enzyme of bacterial metabolism. Now, scientists at the Helmholtz Institute for Pharmaceutical Research Saarland (HIP... Read More
A new study in the Netherlands has found a deep-sea microbe living in high-temperature hydro-thermal vents can thrive on chlorate and perchlorate anions. Perchlorate, an ingredient in rocket fuel and fireworks, is toxic to most organisms.
The researchers, led by Martin Liebensteiner of Wageni... Read More
Following up on our coverage of the work of John Rogers, who is leading efforts at University of Illinois to develop flexible and bioresorbable electronic systems, there’s news now of new findings evaluating such implants in animal models.

Sandia National Laboratories is developing a suite of complementary technologies to help the emerging algae industry detect and quickly recover from algal pond crashes, an obstacle to large-scale algae cultivation for future biofuels. The research, which focuses on monitoring and diagnosing alga... Read More
Shingles vaccine is associated with reduction in both postherpetic neuralgia and herpes zoster, but uptake in the US is low. A vaccine to prevent shingles may reduce by half the occurrence of this painful skin and nerve infection in older people (aged over 65 years) and may also reduce the rate ... Read More
Placement of copper objects in intensive care unit (ICU) hospital rooms reduced the number of healthcare-acquired infections (HAIs) in patients by more than half, according to a new study published in the May issue of Infection Control and Hospital Epidemiology, the journal of the Society for He...

Who knew frozen mice could be so useful? Mouse viruses discovered in a bank of frozen rodents could pave the way for future progress in hepatitis research, enabling scientists to study human disease and vaccines in the ultimate lab animal. In mBio this week, authors from Colombia University and ... Read More
This confocal micrograph, taken as part of a synthetic biology project, shows Bacillus subtilis, a Gram-positive, rod-shaped bacterium that is commonly found in soil. Distinct lineages of bacteria expressing different fluorescent proteins were initially mixed randomly on a petri dish. As the bac... Read More
A study at the Virginia-Maryland Regional College of Veterinary Medicine has identified a chicken-killing virus as a promising treatment for prostate cancer in humans.
Researchers have discovered that a genetically engineered Newcastle disease virus, which harms chickens but not humans, kills... Read More
The Rockefeller University's Luciano Marraffini is interested in understanding how bacteria evolve by incorporating DNA sequences from other bacteria or from the environment into their genomes. His research focuses on the mechanisms that control the traffic of DNA molecules between bacteria.
Nearly half of the world's population is at risk of infection by the dengue virus, yet there is no specific treatment for the disease. Now a therapy to protect people from the virus could finally be a step closer, thanks to a team at MIT.
In a paper published today in the Proceedings of the N... Read More
Technology that enlists natural soil bacteria as 21st century roughnecks now is commercially available and poised to recover precious oil remaining in thousands of exhausted oil wells, according to a scientist who spoke in New Orleans on April 8. His report on a process termed microbially enhanc... Read More
Researchers suspect H7N9 virus is in bird markets as human cases rise rapidly. Virologists know its name: H7N9. What they don’t yet know is whether this novel avian influenza virus — first reported in humans in China less than two weeks ago — will rapidly fizzle out, become established in animal... Read More
The Gulf of Mexico may have a much greater natural ability to self-clean oil spills than previously believed, an expert in bioremediation said here today at the 245th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society.

In the most extensive screen of its kind, Texas Biomed scientists have demonstrated the feasibility of repurposing already-approved drugs for use against highly pathogenic bacteria and viruses. The pathogens included emerging diseases and potential bioterror threats ranging from anthrax to the M... Read More
