Designer Wei Lei poses a challenging, and fascinating question: Would you lick a delicious treat that resembles a prickly cactus or a deadly E. coli bacterium?
The Chinese designer’s collection of sweets, Dangerous Popsicles, transforms frozen sugar water into colorful spiny treats inspired b... Read More
A fast-sensitive “electronic-nose” for sniffing the highly infectious bacteria C-diff, that causes diarrhoea, temperature and stomach cramps, has been developed by a team at the University of Leicester.
Using a mass spectrometer, the research team has demonstrated that it is possible to ident... Read More
DURHAM, NC - Within each strand of DNA lies the blueprint for building an organism, along with the keys to its evolution and survival. These genetic instructions can give valuable insight into why pathogens like Cryptococcus neoformans -- a fungus responsible for a million cases of pneumonia and... Read More
About 50 years ago, electron microscopy revealed the presence of tiny blob-like structures that form inside cells, move around and disappear. But scientists still don’t know what they do — even though these shifting cloud-like collections of proteins are believed to be crucial to the life of a c... Read More
President Ellen Johnson Sirleaf of Liberia on Friday urged the United States to maintain its assistance to her country as it continues to fight to recover from the Ebola outbreak, which began about one year ago.
In a meeting at the White House with President Obama, Ms. Johnson Sirleaf asked f... Read More
An otherwise balanced review of selected aspects of Ebolavirus transmission falls apart when the authors hypothesize that ‘Ebola viruses have the potential to be respiratory pathogens with primary respiratory spread.’
The idea that Ebolavirus might become transmitted by the respiratory route ... Read More
A second American aid worker in Liberia has tested positive for Ebola, according to the Christian humanitarian group she works for.
Nancy Writebol is employed by Serving in Mission, or SIM, in Liberia and was helping the joint SIM/Samaritan's Purse team that is treating Ebola patients in Monr... Read More
Scientists at the University of East Anglia have made a breakthrough in the race to solve antibiotic resistance.
New research published today in the journal Nature reveals an Achilles’ heel in the defensive barrier which surrounds drug-resistant bacterial cells.
The findings pave the way f... Read More
Drawing from his engineering background, Princeton University researcher Alexandre Persat had a notion as to why the bacteria Caulobacter crescentus are curved — a hunch that now could lead to a new way of studying the evolution of bacteria, according to research published in the journal Nature ...

Careful what you sniff. Especially if you work at an industrial hog farm. Because a small study finds that drug-resistant bacteria may hang out in the noses of some workers even after four days away from work following exposure. Almost half of the tested workers continued to harbor drug-resistan... Read More
Using magnetic fields, technique can detect parasite’s waste products in infected blood cells.
Over the past several decades, malaria diagnosis has changed very little. After taking a blood sample from a patient, a technician smears the blood across a glass slide, stains it with a special dye... Read More
These are two harmless lab strains of E. coli. One can ferment the sugar lactose into acidic byproducts and the other cannot. MacConkey media contains an indicator dye that turns from red to yellow when the pH is raised. The four pink streaks were drawn with a culture of the lactose fermenter (t... Read More
Scientists cleaning out an old laboratory on the National Institutes of Health campus in Bethesda, Md., last week came across a startling discovery: vials labeled "variola" — in other words, smallpox.
Under international convention, there are supposed to be only two stashes of this deadly vir... Read More
The enzymes that make copies of the DNA or RNA genomes of viruses – nucleic acid polymerases – can be placed into two broad categories depending on whether or not they require a primer, a short piece of DNA or RNA, to get going. The structure of the primer-independent RNA polymerase of hepatitis... Read More
On May 30, 2012 Brianna Dannen, Public Health Nurse at the Clark County Health District (CCHD), received a call from Bob Williamson at Clark College. Mr. Williamson called to report that a child of a Clark College student enrolled in a microbiology class, BIOL&260, taught by Travis Kibota was i... Read More
A second form of the painful chikungunya virus has appeared in Brazil—one that could more easily spread, including to the U.S.
When a mosquito-borne disease first arrived in the Western Hemisphere last year, humans were relatively lucky. The disease, which causes crippling joint pain persis... Read More
A potentially life-threatening gastrointestinal infection is more common than previously estimated, federal health officials reported Wednesday.
The infection, caused by a bacterium known as Clostridium difficile, or C-diff, causes nearly 500,000 illnesses in the United States each year and k... Read More
Unidentified soil microbes on SDA plates; most colonies are producing compounds (droplets can be seen on top of the colonies; possibly antibiotic producers). This picture was taken by me, Kaitlynn Fenley. The plate is from the class that I am a teaching assistant for at Louisiana State Universit... Read More
The natural photo degradation of diazepam (valium) and similar medicines – followed by bacterial breakdown – may reduce their potentially harmful impact on the UK’s freshwater environment, a team of researchers has said.
Diazepam – used to treat anxiety and other similar conditions – has been... Read More
In 1887, Dr. Joseph Kinyoun set up his one-room Hygienic Laboratory in the Marine Hospital on Staten Island in New York to research cholera and other infectious diseases such as diphtheria, typhoid, smallpox, typhus, plague and tuberculosis. This was the beginning of the National Institutes of H... Read More
