Since the 1950s farmers have fed antibiotic growth promoters (AGPs) to livestock. Overusing these substances can create superbugs, pathogens that are resistant to multiple drugs and could be passed along to humans. Mindful of that, companies such as Perdue Farms have stopped using the drugs to m... Read More
Rivers and streams could be a major source of antibiotic resistance in the environment.
The discovery comes following a study on the Thames river by scientists at the University of Warwick’s School of Life Sciences and the University of Exeter Medical School.
The study found that greater n... Read More
What do your mouth and your behind have in common? They're linked by a bug that we thought was usually benign, but may in fact have a much darker side.
Fusobacterium nucleatum is a common bacterium that lives in our mouths, often without causing any ill effects, although it is also frequently... Read More
Pictured here are blue colonies of Methicillin-resistant Staphylococcus aureus (MRSA) growing on Remel Spectra MRSA medium. Spectra media contains a chromogen that yields a blue color as a result of phosphatase activity. The phosphatase enzyme is present in many staphylococci, including Staphylo... Read More
Imagine thousands of copies of a single protein organizing into a coat of chainmail armor that protects the wearer from harsh and ever-changing environmental conditions. That is the case for many microorganisms. In a new study, researchers with the U.S. Department of Energy (DOE)’s Lawrence Berk... Read More
Researchers have sequenced the genomes of all 15 species of Darwin’s finches, revealing a key gene responsible for the diversity in the birds’ beaks. The study, published online in Nature this week, also redraws the family tree of these iconic birds, whose facial variations helped Charles Darwin... Read More
Viruses are masters of outsourcing, entrusting their fundamental function – reproduction – to the host cells they infect. But it turns out this highly economical approach also creates vulnerability.
Researchers at Rockefeller University and their collaborators have found an unexpected way the... Read More
Photograph of 400X magnified image of biogas digestor sample. A strange spiraled type microbe seen (probably like left handed DNA helix). The microbe is shown with an arrow. Has anyone seen such microbial structure? Read More

With minor tinkering, a peptide—a tiny protein—from the skin of a frog could be fashioned into a novel antibiotic that would lack the toxic byproducts of some more conventional drugs. More importantly, such peptides would represent a new class of antibiotics, at a time when new classes are so... Read More
An international team led by Uppsala University scientists has succeeded, for the first time, in depicting intact live bacteria with an X-ray laser. This technique, now described in the journal Nature Communications, can give researchers a clearer understanding of the complex world of cells.

More than 600 years after the bubonic plague wiped out about half of Europe, scientists still don’t fully understand how bacteria that cause the disease travel from the site of a fleabite to the lymph nodes, where the rampage truly begins.
Researchers who’ve been studying the bacteria say the... Read More
In recent years, public health experts have increasingly explored the idea of eliminating the most dangerous malaria-causing parasite. But they have questioned whether getting rid of this species, called Plasmodium falciparum, would allow other species of the parasite to simply jump into the gap... Read More

When I jetted off to South America a year and a half ago, my doctor sent me with a bottle of Ciprofloxacin in case of an unfortunate bout of food poisoning. I thought little of it then, but what does it mean when millions of travelers head to developing countries with antibiotics?

An experimental medication that targets a protein in Ebola virus called VP24 protected 75% of a group of monkeys that were studied from Ebola virus infection, according to new research conducted by the U.S. Army, in collaboration with Sarepta Therapeutics, Inc. The study was published this week ... Read More
Scientists have revealed how coral-dwelling microalgae harvest nutrients from the surrounding seawater and shuttle them out to their coral hosts, sustaining a fragile ecosystem that is under threat.
Coral reefs are the jungles of the oceans, home to some of the planet's most fertile fishing g... Read More
Jason Roberts, a virologist at the Victorian Infectious Disease Reference Laboratory in Melbourne, Australia, creates three-dimensional simulations of viruses showing how the molecules that make up the capsid and genome might move in very short periods of time. I visited Jason in his laboratory ... Read More
We’re in the midst of an outbreak of debate, people arguing the merits of vaccinations. Its symptoms include feverish rhetoric and noxious op-eds. In an attempt to stem the spread of unhealthy attitudes toward science and misinformation about vaccines, the Bill & Melinda Gates Foundation sponsor... Read More
By the dawn of the 19th century, tuberculosis had killed one in seven of all people that had ever lived. Doctors believed it was hereditary, but had begun to observe that fresh air and outdoor living could sometimes change the course of the illness. Physician and TB patient Edward Trudeau was co...
