A chemical analysis of the bones of ancient Nubians shows that they were regularly consuming tetracycline, most likely in their beer. The finding is the strongest evidence yet that the art of making antibiotics, which officially dates to the discovery of penicillin in 1928, was common practice n... Read More
Knowing an organism's metabolism can give scientists essential insights into how the organism uses its resources. These insights can then enable them to tweak the metabolism to enhance the microbe's use of these resources in beneficial ways, such as to reduce contamination in soil or to produce... Read More
Mary J. Blige is partnering with NASA to encourage girls and young women to pursue careers in Science, Technology, Engineering and Mathematics (STEM). NASA released two public service announcements featuring Blige and space shuttle astronaut Leland Melvin this week on NASA TV online. In addition... Read More
Microbes could soon be used to convert metallic wastes into high-value catalysts for generating clean energy, say scientists writing in the September issue of Microbiology.
Researchers from the School of Biosciences at the University of Birmingham have discovered the mechanisms that allow the... Read More
"Potential link between swine flu vaccine and narcolepsy", ran the headlines last week reporting a spate of cases of the rare sleeping disorder in children. But anyone thinking of forgoing their regular flu vaccination as a result is being advised to think again.
Reports of possible links bet... Read More
Like living bone, concrete could soon be healing its own hairline fractures – with bacteria in the role of osteoblast cells. Worked into the concrete from the beginning, these water-activated bacteria would munch food provided in the mix to patch up cracks and small holes.
Concrete reinforced... Read More
In a world where doctors can treat the most devastating illnesses, the common cold remains elusive.
That's because up until recently, scientists knew little about the viruses that spread this seasonal nuisance.
But that may be changing now that researchers have mapped one virus's atomic st... Read More

Some bacteria, the most antibiotic-resistance ones, sacrifice themselves so that their fellow bacteria have a better chance at survival.
Researchers working on the question of antibiotic resistant found that in an experimental Escherichia coli colony, the most antibiotic resistant bacteria in... Read More
An antibacterial peptide developed by Laszlo Otvos, a research professor of biology in Temple's College of Science and Technology, looks to be a highly-effective therapy against infections in burn or blast wounds suffered by soldiers.
Otvos and his collaborators found that when given intramus... Read More
For years, researchers have been unable to image the viruses they were trying so hard to destroy, but now not only has that become possible, but they can also use the microorganisms to deliver drugs.
This is possible thanks to efforts by a team of investigators based at the University of Cali... Read More
HIV-positive women who are breastfeeding should not be given vitamin A supplements because it increases the risk of transmitting the AIDS virus to their infants, researchers said Thursday. Mother-to-child transmission of HIV has been largely controlled in the United States and other developed co... Read More
South Dakota State University research is exploring a "fusion strategy" for making improved vaccines to protect pigs and humans against some strains of E. coli.
The SDSU researchers altered the toxins produced by a form of E. coli and genetically fused the non-poisonous "toxoid" to a protein... Read More
Water, water everywhere, but in the developing world or in areas ravaged by natural disasters – like the ongoing flooding in Pakistan, for instance – there’s often not a clean, purified drop to be found. Water is usually made potable in such places via filters that physically trap bacteria as wa... Read More
How did bacteria spread through two Iowa egg farms, leading to the largest Salmonella enteritidis outbreak ever recorded in the U.S.? Take your pick. Stomach-turning inspection reports released Monday by the Food and Drug Administration found wild birds, which can carry the disease, flying and... Read More
We tend to think of bacteria as engaging in chemical warfare only when they attack us, wreaking havoc on our cells. But the microbiome is a vicious place, with many species hurling toxins at each other, attempting to gain a competitive advantage. A bacterium called Bacillus subtilis goes beyond... Read More
Infrared spectroscopy can detect E. coli faster than current testing methods, and can cut days off investigations of outbreaks, according to a study at Purdue University.
Lisa Mauer, an associate professor of food science, detected E. coli in ground beef in one hour using Fourier transform in... Read More
Scientists from the National Institutes of Health and University of Chicago have found a promising treatment method that in laboratory mice reduces the severity of skin and soft-tissue damage caused by USA300, the leading cause of community-associated Staphylococcus aureus infections in the Unit...

Group A Streptococcus (GAS) is responsible for infections ranging from “strep throat” to necrotizing fasciitis, aka the “flesh-eating disease”, a severe and invasive condition that has seen a marked increase in incidence in the past 30 years. The increase has been pinned on a single clone of th... Read More
