The rise of antibiotic-resistant bacteria has initiated a quest for alternatives to conventional antibiotics. One potential alternative is PlyC, a potent enzyme that kills the bacteria that causes strep throat and streptococcal toxic shock syndrome. PlyC operates by locking onto the surface of a... Read More
In the US alone, more than 500,000 suffer and 15,000 die every year from uncontrollable diarrhea caused by infection with Clostridium difficile. These rod-shaped bacteria are commonly found in the environment and even in our bodies, but have lately become a major concern in hospitals where antib... Read More
A study released today from the upcoming issue of the Journal of the Pediatric Infectious Diseases Society (JPIDS) found that taking early and repeated white blood cell counts (WBC) is critical in determining whether infants have pertussis and which of those children are at highest risk of death...

Cholera could be contained in Haiti by vaccinating less than half the population, University of Florida researchers suggest in a paper to be published Thursday in the journal Scientific Reports.
The work places UF's Emerging Pathogens Institute in the pro-vaccination camp in an ongoing intern... Read More
In the mid-19th century, if you had wanted to have a scientific fight, you could have picked no better subject than palaeontology. Fossils pouring out of the mines, quarries and railway cuttings of the industrial revolution were undermining the biblical accounts of creation and early history, th... Read More
It is not your imagination — more people you know are sick this winter, even people who have had flu shots.
The country is in the grip of three emerging flu or flulike epidemics: an early start to the annual flu season with an unusually aggressive virus, a surge in a new type of norovirus, an... Read More
In mBio this week, a new study offers hope for a vaccine against group A Streptococcus (GAS). GAS is familiar to most of us as the cause of Strep throat, but it’s more than that. It’s also the cause of some serious and invasive infections, including septic arthritis, impetigo, and necrotizing fa... Read More
Deans of public health schools in the United States have sent a letter to President Obama, in which they criticize the use of a vaccination campaign by the Central Intelligence Agency in Pakistan to hunt for Osama bin Laden. I wonder if he will reply. Read More
The World Health Organization’s campaign to eradicate poliomyelitis made impressive inroads in 2012: only 212 cases were reported, compared with 620 the previous year; moreover, India remained polio-free. The dark side of this story is that as wild polio is eliminated, vaccine-associated poliomy... Read More
Based on the price of medication, consumers make irrational inferences about their risk of getting sick. The study, published in Journal of Consumer Research, finds that consumers make judgments about their risk of catching an illness based on the cost of its medication. The higher the price, th...

Researchers have discovered a new compound that restores the health of mice infected with methicillin-resistant Staphylococcus aureus (MRSA), an otherwise dangerous bacterial infection. The new compound targets an enzyme not found in human cells but which is essential to bacterial survival.
T... Read More
In a recent post I shared with you how different microbes come together to breathe as one. In some cases, all it takes is the presence of conductive minerals such as magnetite to facilitate the exchange of metabolic electrons between two microbial partners. This allows the team to catalyze a red... Read More
A research team of scientists from EMBL Grenoble and the IGBMC in Strasbourg, France, have, for the first time, described in molecular detail the architecture of the central scaffold of TFIID: the human protein complex essential for transcription from DNA to mRNA. The study, published January 7 ... Read More
New research led by the Karolinska Institutet, Sweden and the University of Glasgow, Scotland, has identified a link between a human gene and the composition of human gastrointestinal bacteria. In a study published as a letter to the journal Gut, the team outline new evidence suggesting that th... Read More
If you were a science professor, and you received two equally strong applications for the position of laboratory manager, one from a female, one from a male, which one would you pick? The answer might surprise you. Read More
Dengue epidemics continue to break out in South America. Last year, more than 100,000 people contracted dengue fever in Rio de Janeiro alone. In its fight against the deadly virus, the city is employing unique methods.
The endless battle against Rio de Janeiro's mosquitoes takes Luciano do Ca... Read More
Discover Magazine is partnering with Instructables and SciStarter, an online citizen science community, to solve real problems facing researchers. The Citizen Science Contest is your opportunity to help millions of regular people contribute to scientific discovery. Prizes include a Celestron tel... Read More
Bacteria that live almost a mile under the surface of the ocean, where light is scare, have adapted biological ways to harness tiny amounts of light very efficiently, and in some cases can use photosynthesis to convert 100 percent of the light they find into electricity. In contrast a typical so... Read More
Deep in the thicket of west Africa, on a bamboo bridge strung over raging waters, Erica Ollmann Saphire groped through the dark toward a village where pestilence can snuff out life with ruthless efficiency.
She was looking for rodents. The Scripps Research Institute biologist wanted to know h... Read More
