n this series on superbugs—meaning bacteria that are becoming increasingly resistant to antibiotics—we’ve looked at germs on a national level. But you probably already know that bugs don’t respect borders: Drug resistance is definitely a global problem. And there are two particularly troubling e... Read More
A 65-year-old man infected with a new SARS-like virus died of multiple organ failure on Monday in France.
He was the first French patient to die from the condition, which is known as Middle East Respiratory Symptom Coronavirus, or MERS-CoV. As of Wednesday, 49 people have been infected with t... Read More
Have you googled anything today? If so, you may have noticed that the Google Doodle looks different. That's because today is the 161st anniversary of the birth of German bacteriologist, Julius Richard Petri. He was the inventor of the Petri dish – one of the most ubiquitous items used by microbi...

SOMETIMES, to achieve broad cultural immortality, it’s less what you made your name in — and much more what you put your name on.
That is why, in the wider world beyond the lab, Robert Bunsen’s name burns so bright. And if anyone understands the conditions for how our culture behaves (and mut... Read More
Scientists are great at growing E. coli in the lab. They know exactly under which conditions various strains thrive. Unfortunately, there is only so much that can be learned from the bacteria’s behavior in an ideal, isolated and ultimately unrealistic environment. That is why a group of research... Read More
The head of the World Health Organization warned the world this week of a new virus, awkwardly dubbed MERS-CoV, found in Saudi Arabia.
"Looking at the overall global situation, my greatest concern right now is the novel coronavirus," Margaret Chan said, calling it "a threat to the entire worl... Read More
A new research project involving researchers from Bath aims to develop novel self-healing concrete that uses an inbuilt immune system to close its own wounds and prevent deterioration.
The life of concrete structures is reduced when the material cracks and water is able to get at the steel re... Read More
A method that promises to reduce by more than half the time it takes health officials to identify Salmonella strains has been developed by researchers in Penn State's College of Agricultural Sciences.
The finding is important because it promises to significantly speed up the response to many ... Read More
Bathing all patients daily with a germ-killing soap and swabbing antibiotic ointment in their noses may be the best way to reduce the spread of deadly infections, including MRSA.
In a new study, these measures reduced the bloodstream infections caused by dangerous pathogens, including the dru... Read More
The first description of the 4-million-atom structure of the HIV’s capsid, or protein shell, could lead to new ways to fight the virus. The findings are highlighted on the cover of the May 30 issue of Nature.
“The capsid is critically important for HIV replication, so knowing its structure in... Read More
Bloodstream infections cut by more than 40 percent in study of over 74,000 patients. Using germ-killing soap and ointment on all intensive-care unit (ICU) patients can reduce bloodstream infections by up to 44 percent and significantly reduce the presence of methicillin-resistant Staphylococcus ...

Virus particles of the same type had been thought to have identical structures, like a mass-produced toy, but a new visualization technique developed by a Purdue University researcher revealed otherwise.
Wen Jiang, an associate professor of biological sciences, found that an important viral s... Read More
Researchers apply a new experimental approach to visualize the turbulent motion of swimming bacteria and propose a minimal model that captures their observations.
Bacteria are among the oldest and most abundant living species on Earth, and their activity influences the planet’s environmental ... Read More
Usually, when you mention bacteria in connection with water, it’s a bad thing. But one Texas A&M engineering researcher believes the right bacteria are a natural weapon for fighting an emerging water contaminant: estrogen.
Increasingly sensitive methods of screening water for polluting substa... Read More
Researchers and physicians in the field could soon run on-the-spot tests for environmental toxins, medical diagnostics, food safety and more with their smartphones.
University of Illinois at Urbana-Champaign researchers have developed a cradle and app for the iPhone that uses the phone's buil... Read More
It's a question we ask about many recently discovered bacteria: What, exactly, do the Verrucomicrobial do in the environment? Since their discovery, representatives of the phylum Verrucomicrobia have been detected in soil and aquatic environments around the world, but we have very few existing i... Read More
For the first time, researchers have found a particular kind of molecular switch in the food poisoning bacteria Salmonella Typhimurium under infection-like conditions. This switch, using a process called S-thiolation, appears to be used by the bacteria to respond to changes in the environment du... Read More
A sugar polymer found on the cell surface of multiple pathogens could be key to developing a broad-spectrum vaccine. Developing new vaccines to protect against diseases that plague humans is fraught with numerous challenges—one being that microbes tend to vary how they look on the surface to avo... Read More
New research from the University of Southampton shows that copper and copper alloys will rapidly destroy norovirus – the highly-infectious sickness bug. The virus can be contracted from contaminated food or water, person-to-person contact, and contact with contaminated surfaces, meaning surfaces... Read More
On a sunny Wednesday, with a faint haze hanging over the Rockies, Noah Fierer eyed the field site from the back of his colleague’s Ford Explorer. Two blocks east of a strip mall in Longmont, one of the world’s last underexplored ecosystems had come into view: a sandstone-colored ranch house, cod... Read More
