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
This episode: Defective phages in bacterial genomes can still have burdensome effects! Why do the bacteria keep them around?

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
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
In the search for a renewable energy source, systems using algae look like a good bet. Algae can grow quickly and in high concentrations in areas unsuitable for agriculture; and as they grow, they accumulate large quantities of lipids, carbon-containing molecules that can be extracted and conver...

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
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...

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....

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
In the first evidence that natural selection favors an individual's infection tolerance, researchers from Princeton University and the University of Edinburgh have found that an animal's ability to endure an internal parasite strongly influences its reproductive success. Reported in the journal ... Read More
It came as a surprise to me recently to realize how much is known about the immune responses of plants and, moreover, how much there is to know. There is, I found, detailed molecular information about how our botanical cousins defend themselves against the onslaught of infectious agents. Perhaps... 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...

Scientists have long believed that microorganisms that produce methane swim toward the hydrogen gas they need to stay alive, but it has been too hard to prove in the lab.
Montana State University researchers have now overcome those challenges, allowing them to verify it for the first time, sa... Read More
As a virologist who has worked on poliovirus since 1979, I would be remiss if I did not note that today, 24 October, is World Polio Day. World Polio Day was established by Rotary International over a decade ago to commemorate the birth of Jonas Salk, who led the first team to develop a vaccine a... 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
Mathematicians have found that by varying the timing of treatments, doctors may be able to increase the odds that a disease outbreak will die off suddenly.
Herding cats is a cakewalk compared with getting people to take flu vaccine shots in the last weeks of summer—work, school, limited pharm... 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
To the collection of avian influenza viruses known to sporadically infect humans – H5N1, H7N9, H7N2, H7N3, H7N7, H9N2, and H10N7 – we can now add H10N8, recently found in two individuals in China. Avian influenza virus H10N8 was first detected in tracheal aspirates from a 73 year old woman who w... Read More
The TWiV gang answers follow-up questions about the Ebola virus outbreak in West Africa, then discuss treatment of disseminated multiple myeloma with oncolytic measles virus.
n a groundbreaking study, researchers say injecting bacteria into a tumor helped shrink it.
Bacteria are generally considered more foe than friend, but that may change, if results from a pioneering study are confirmed.
Reporting in the journal Science Translational Medicine, scientists led... Read More
