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
In this blog post, I discuss how students begin to find their "path" to a career that they will love in science. I aIso write about the late, great Richard Feynman. 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
UCLA researchers now have the first evidence that bacteria ingested in food can affect brain function in humans. In an early proof-of-concept study of healthy women, they found that women who regularly consumed beneficial bacteria known as probiotics through yogurt showed altered brain function,... Read More
The word 'unnatural' is often used to describe what's considered weird or unusual. But is anything weirder than nature?
Just look at 17-year cicadas, poised to flood the U.S. East Coast after having stayed underground since Bill Clinton was President. And cicadas are just the start: Biology a... Read More
A simpler and faster way of producing designer bacteria used in biotechnology processes has been developed by University of Adelaide researchers.
The researchers have developed a new one-step bacterial genetic engineering process called ‘clonetegration’, published in the journal ACS Synthetic... Read More
(op-ed piece from a scientist in the United Arab Emerates)
When we think of vibrant biodiversity, the Amazonian jungles, the American Great Plains and the vast oceans come to mind.
And for good reason. They are a prime source of pharmaceuticals, nutritionals and biomass for energy products... Read More
Scientists who worked with the Nobel prize-winning pioneer discuss his legacy alongside footage and previously unseen interviews. Max Perutz, the Austrian-born British molecular biologist, founded the MRC Laboratory of Molecular Biology (LMB) at Cambridge University in the postwar years where he... Read More
Now nearly a decade into her planned 3 month only expedition to Mars, NASA's longest living rover Opportunity, struck gold and has just discovered the strongest evidence to date for an environment favorable to ancient Martian biology – and she has set sail hunting for a motherlode of new clues a...

A team of researchers has captured images of green alga consuming bacteria, offering a glimpse at how early organisms dating back more than one billion years may have acquired free-living photosynthetic cells.
This acquisition is thought to have been a critical first step in the evolution of ... Read More
In this blog entry, I discuss a talk I attended at ASMCUE about "Citizen Science" and how some of my own work appeared in that talk! It is a vital that we scientists explain not just what we do, but why it is so fascinating to us...by involving the public! Read More
The normally civil world of international health diplomacy was shattered yesterday, when Saudi Arabia complained that a patent taken out by Dutch scientists who isolated the Middle Eastern Respiratory Syndrome (MERS) virus was impeding Saudi efforts to track the virus within its own borders.
