Federal officials today announced the first case of Ebola diagnosed in the U.S. The male patient was admitted to Texas Health Presbyterian Hospital Dallas and placed in strict isolation on September 28 after flying from Liberia to visit family in north Texas. The patient left Liberia on Septembe... Read More
A patient with exposure to the Ebola virus while in Sierra Leone has arrived safely at the NIH Clinical Center for observation and to enroll in a clinical protocol. Read More
Remember that worrisome new form of botulinum toxin we told you about in late 2013, the one that supposedly had to be kept secret out of fear it could be used as a bioweapon that would evade all of our medical defenses?
Well, as it turns out, it's not that scary after all. The antitoxin store... Read More
Photosynthesis is probably the most well-known aspect of plant biochemistry. It enables plants, algae, and select bacteria to transform the energy from sunlight during the daytime into chemical energy in the form of sugars and starches (as well as oils and proteins), and it involves taking in ca...

A hinge in the RNA genome of the virus that causes hepatitis C works like a switch that can be flipped to prevent it from replicating in infected cells. Scientists have discovered that this shape is shared by several other viruses—among them one that kills cancer cells.
That’s Seneca Valley v... Read More
We, as most animals, host many different beneficial bacteria. Being beneficial to the host often pays off for the bacteria, as success of the host determines the survival and spread of the microbe. But if bacteria grow too much they may become deadly. In a new study published in the latest editi... Read More
Humans are not the only primates ravaged by the deadly Ebola virus. Chimps and gorillas are also susceptible to the disease. The current Ebola epidemic, the biggest in human history, may have started with the butchering of an infected fruit bat. But it just as easily could have come from a chimp... Read More
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
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
Saudi Arabia has not done enough to investigate and control a deadly new MERS virus that has killed hundreds of people there and remains in many ways a mystery, United Nations health experts said on Monday.
Cases of Middle East Respiratory Syndrome (MERS) are surging again, but Saudi health o... 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
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
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 ...

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
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
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
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
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
