New national drinking water rules are expected to lead to fewer dangerous pathogens coming out of the tap.
The new regulation, which was announced last month and takes effect within three years, switches focus to a type of bacteria that more accurately reflects the presence of pathogens that ... Read More
A new theory of how plant photosynthesis involves quantum coherence has been suggested by physicists in the UK, Germany and Spain. This latest research is based on the study of organisms that live deep under the sea yet are able to convert sunlight into energy. The study suggests that molecular ... Read More
Poliovirus has made the cover of Time magazine. The Time cover image for the 14 January 2013 issue is a model of poliovirus bound to a soluble form of its cellular receptor, CD155. I was part of the team that solved the structure of this complex in 2000, together with the laboratories of Jim Hog... Read More
Yesterday many US newspapers carried front-page stories on the severity of influenza so far this season. The New York Times story began with “It is not your imagination — more people you know are sick this winter, even people who have had flu shots.” Is this really a bad flu season? Read More
As anyone who suffers from recurrent cold sores knows, herpes is a master escapist. This family of viruses – including strains that cause lesions on the genitals, infectious mononucleosis (glandular fever) and, in some cases, blindness and birth defects – is able to wriggle free of the body's de...

If you haven't caught the flu yet or don't know someone who has, you might want to buy a lottery ticket today. You're one lucky person.
As The Associated Press writes, "from the Rocky Mountains to New England, hospitals are swamped with people with flu symptoms." More than 40 states report "w... Read More
The detailed changes in the structure of a virus as it infects an E. coli bacterium have been observed for the first time, report researchers from The University of Texas at Austin and The University of Texas Health Science Center at Houston (UT Health) Medical School this week in Science Expre...

By varying laser and electric fields, scientists can use tiny centrifuge-like whirlpools to separate particles and microbes.
The technology could bring innovative sensors and analytical devices for lab-on-a-chip applications, or miniature instruments that perform measurements normally requiri... Read More
A new study by NYU School of Medicine researchers reveals that an especially virulent strain of the gut bacterium Helicobacter pylori (H. pylori) isn't implicated in the overall death rate of the U.S. population, and may even protect against stroke and some cancers. The findings, based a nationw... Read More
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.
