Most bacteria divide quite precisely and their daughter cells are often the same size. The reason for this accuracy is not really known, but it must be important because it is such a frequent phenomenon. This requires good measuring sticks, systems that calculate distance from the ends and restr... Read More
People living near pig farms or agricultural fields fertilized with pig manure are more likely to become infected with methicillin-resistant Staphylococcus aureus (MRSA) bacteria, according to a paper published today in JAMA Internal Medicine1.
Previous research has found that livestock worke... Read More
The armed guards at Mali's Bamako Senou International Airport had never seen a German shepherd before. The only dogs they were familiar with were the small, scrappy mixed breeds that are common in West Africa. So when Dana, a wolf-like purebred from California, stepped off a plane and into the a...

We live in a world run by microbes, the vast majority of which we have yet to identify or name. We can only refer to them collectively as the microbial dark matter (MDM). However you define a prokaryotic species, and however you tally them once identified, there is a huge gap between the 12,000 ... Read More
The gut bacteria in horses are being researched at the University of Pennsylvania, in a series of projects that scientists hope will ultimately benefit animal and human health.
Researchers at the university’s School of Veterinary Medicine are leading five pilot projects as part of the wider i... Read More
Study contradicts notion that microbes consumed most of the gas after 2010 Deepwater Horizon spill.
When the blowout of the Deepwater Horizon oil well sent some 400,000 tonnes of methane into the Gulf of Mexico in April 2010, many scientists and others feared it would linger. So researchers w... Read More
Two health care workers went to the emergency room with flu-like symptoms after coming into contact with a patient confirmed to have Middle East Respiratory Syndrome, or MERS, officials said Tuesday.
The Florida patient represents the second confirmed case of MERS brought into the United Stat... Read More
Infection from salmonella bacteria, the most common form of food poisoning in the U.S., declined last year but the overall rate of foodborne illness is holding stubbornly steady despite new measures intended to curb it, according to data released Thursday by the federal Centers for Disease Contr...

Researchers are using new nanoscale imaging approaches to shed light on the dynamic activities of rotaviruses, important pathogens that cause life-threatening diarrhea in young children. Once a rotavirus enters a host cell, it sheds its outermost protein layer, leaving behind a double-layered pa... Read More
By tracing the evolutionary origin of a drug-like protein ring found in sunflowers, Australian and US scientists have discovered a diverse, 18-million-year-old group of buried proteins in daisy seeds.
Researchers at The University of Western Australia, working with academics from The Universi... Read More
Wyoming’s resurgent uranium industry could get a further boost from University of Wyoming scientists, whose research on post-mining environmental restoration is yielding extremely promising results.
Research in UW laboratories has shown that stimulating growth of native bacteria could be a mo... Read More
I offer this as an echo to Elio's post from last October, Teaching E. coli to Endocytose. There Elio reported the recent education of E. coli by the heterologous expression of a mammalian gene. I tell of a bacterium instructed by a phage.
Apparently Pseudomonas phage φ6 missed that classic 19... Read More
A future computer might be a lot slimier than the solid silicon devices we have today. In a study published in the journal Materials Today, European researchers reveal details of logic units built using living slime molds, which might act as the building blocks for computing devices and sensors....

A new type of botulinum toxin – the deadliest substance known – has been discovered. Because it does not yet have an antidote, the DNA sequence behind it has been withheld from public databases. This is the first time a sequence has been kept secret over security concerns.
Injecting a mere 2 ... Read More
Slothful response from regulators and manufacturers means antibiotic resistance is missed. Bacteria that are resistant to almost all antibiotics are dreaded by physicians and patients alike. Finding such microbes in a hospital is bad enough, but failing to detect them can lead to something much ... Read More
Enhancing the discoverability of public health and epidemiology research data is a key to ensuring that it gets more widely used. This was the topic of a recent workshop hosted by the London School of Hygiene and Tropical Medicine, where researchers and data experts explored the findings of a re... Read More
Native bacteria living inside mosquitoes prevent the insects from passing Wolbachia bacteria -- which can make the mosquitoes resistant to the malaria parasite -- to their offspring, according to a team of researchers.
The team found that Asaia, a type of bacteria that occurs naturally in Ano... Read More
The EU Commission has agreed new rules to limit the spread of a deadly swine disease that has killed millions of piglets in the US.
Porcine Epidemic Diarrhoea virus (PEDv) has wiped out around 10% of the American herd in a year.
While the EU rejected an outright ban on live pig imports, it... Read More
Health officials are still learning from the fungal outbreak tied to tainted steroid pain injections made at the now-shuttered New England Compounding Company.
Researchers now know that most patients' immune systems didn't try to fight off the deadly fungi as it burrowed into their spinal col... Read More
Despite major efforts to keep operating rooms sterile, surgical wound infections remain a serious and stubborn problem, killing up to 8,200 patients a year in the U.S. A study by Columbia University Medical Center (CUMC) researchers suggests that narrow-spectrum ultraviolet (UV) light could dram...
