In 3500 BCE, Egyptian rulers built a menagerie of exotic creatures within the ancient capital of Hierakonpolis. Archaeologists have found 112 animal skeletons at this site: the first zoo on Earth. But from this earliest exhibition of the natural world through today’s most famous animal displays,... Read More
The delay between the time when a disease outbreak becomes possible and when it actually happens depends chiefly on how frequently infection is introduced to the population and how quickly the number of cases caused by a single individual increases, according to new research from the University ...

A research team at Washington University School of Medicine in St. Louis has established a mouse model for testing of vaccines and therapeutics to battle Zika virus. Read More
Communication of experimental results via publishing is one of the most important steps of the scientific method; if you don’t share your results, how will knowledge within a field grow? A well-written article contextualizes the author’s data into a broader scientific landscape, which allows rea... Read More
The TWiV academia discuss induction of diarrhea by the capsid protein of an astrovirus, and association of a fungal RNA virus with white-nose syndrome of North American bats.
Robots help sort patient samples, test clinical specimens, and analyze the results. Now a study shows that robots, in the form of drones, can help move our samples from place to place, with little effect on the analytical outcome.
Drone transport made a news splash when Amazon proposed using ... Read More
Our work on Zika virus has utilized two different antibodies to detect Zika virus replication within cells. I described one antibody, directed against double-stranded RNA (dsRNA) in a previous article. A second antibody directed against a Zika virus protein has also been useful...

In 2009, fish in Israel began dying in droves. And not just any fish, but the St. Peter’s fish, tilapia in the Sea of Galilee—the fish famed in the Bible for feeding the multitudes and paying the temple tax for St. Peter.
As head of the fish disease laboratory for Israel’s Ministry of Agricul... Read More
Washington, DC – August 8, 2016 – For the first time in Brazil, a particular antibiotic resistance mechanism conferring resistance to the important antibiotic, colistin, has been detected in a human. It was in a strain of Escherichia coli that was isolated from a diabetic patient’s foot infectio... Read More
An emerging field, known as implementation science, may help reduce the nearly 150,000 instances of mother-to-child HIV transmissions that occur annually around the world, mostly in developing countries. A team of scientists and program managers, led by the National Institutes of Health, has bee... Read More
Washington, DC – August 2, 2016 – Adjuvants – ingredients added to vaccinations for influenza and other viruses to help boost their effectiveness – can increase a host’s immune response but not enough to protect the obese against the ill effects of the flu, according to a mouse study published t...

Over the last half century, a number of diseases have spilled over from animals to humans with increasing frequency. What's behind the rise in spillover diseases? What can we do to stop them? Spillover — Zika, Ebola & Beyond is a harrowing documentary that follows scientists into the world's ... Read More
Donald Trump has a long history of promulgating anti-vaccine conspiracy theories (contrary to received wisdom, the anti-vaxx movement draws most of its support from the political right, not liberals), and the tireless leaders of the anti-vaccine movement now claim to have met with Trump and rece...

Washington, DC – July 11, 2016 - Five percent of adults from a cohort of 400 people reported using antibiotics without a prescription during the previous 12 months. Twenty-five percent said they would use antibiotics without contacting a medical professional. These findings demonstrate yet anoth... Read More
Given the complexity of host-microbiota symbioses, scientists and philosophers are asking questions at new biological levels of hierarchical organization—what is a holobiont and hologenome? When should this vocabulary be applied? Are these concepts a null hypothesis for host-microbe systems or l... Read More
A growing body of evidence indicates that the trillions of microbes that live on and inside our bodies affect our health. Collectively, these resident microbes form our microbiome.
In a new paper appearing in the journal Cell Host & Microbe, researchers at the University of Washington report ... Read More
Studying a new type of pinhead-size, lab-grown brain made with technology first suggested by three high school students, Johns Hopkins researchers have confirmed a key way in which Zika virus causes microcephaly and other damage in fetal brains: by infecting specialized stem cells that build its...

How is it that we are we able to devote so little of our personal time and energy to producing or acquiring the healthy, safe food that we consume multiple times every day? A large part of the reason we seldom worry about agricultural output is that most of us benefit enormously from modernized,... Read More
No one knows for sure how they got there. But the discovery that bacteria that normally live in the gut can be detected in the lungs of critically ill people and animals could mean a lot for intensive care patients.
Today, scientists are reporting that they found gut bacteria in the deepest r... Read More
