The Centers for Disease Control and Prevention is working with public health, agricultural, and academic experts to understand the possible threat posed by the spread of the Asian longhorned tick (Haemaphysalis longicornis) in several U.S. states since its discovery in 2017, according to today’s Morbidity and Mortality Weekly Report.
“The full public health and agricultural impact of this tick discovery and spread is unknown,” said Ben Beard, ...Read More →
Diseases have repeatedly spilled over from wildlife to humans, causing local to global epidemics, such as HIV/AIDS, Ebola, SARS, and Nipah.
A new study by researchers of disease transmission in bats has broad implications for understanding hidden or “cryptic” connections that can spread diseases between species and lead to large-scale outbreaks.
By dusting bats with a fluorescent powder that glows under ultraviolet ...
Diarrheal disease, a preventable and treatable illness, remains the second-leading cause of death in children under the age of 5 and a persistent public health threat in sub-Saharan Africa.
Researchers have now uncovered how surface water dynamics may increase the vulnerability of dependent populations to diarrheal disease and climate change.
VectorBiTE: Vector Behavior in Transmission Ecology by the Quantitative Ecological Dynamics Lab
JUNE 21, 2018 | BY FADOUA EL MOUSTAID
The Quantitative Ecological Dynamics Lab, led by Leah Johnson, just wrapped up a third VectorBiTE workshop at the Asilomar Conference Center in Pacific Grove, CA. The VectorBiTE project is a Research Coordination Network that seeks to build a collaborative network of interdisciplinary researchers to investigate the effect of vector behavior and life history on transmission dynamics. More about the goals and the organizing team can be ...Read More →
March 1, 2018 | As annual flu shot patrons know, immune systems are not perfect and must be constantly reinforced to protect against rapidly evolving pathogens.
New research shows that, in the case of a common backyard bird, imperfect immunity to a dangerous pathogen that causes “bird pink eye” actually makes the pathogen stronger and more dangerous for its next victim. The findings — from a multi-university team led by ...
Climate change could wipe out a third of all parasite species on Earth, according to the most comprehensive analysis to date.
Tapeworms, roundworms, ticks, lice and fleas are feared for the diseases they cause or carry, but scientists warn that they also play a vital role in ecosystems. Major extinctions among parasites could lead to unpredictable invasions of surviving parasites into new areas, affecting wildlife and humans and making a “significant contribution” to the sixth ...Read More →
Smithsonian Scientists Release Frogs Wearing Mini Radio Transmitters Into Panamanian Wilderness
Lisa Belden, Angie Estrada, and Daniel Medina are Global Change Center affiliates in the Department of Biological Sciences at Virginia Tech. Their amphibian research was recently featured in the following video and online article at The Smithsonian’s National Zoo and Conservation Biology Institute. The article originally appeared as a blog post on the website of the Amphibian Rescue & Conservation Project.
“Ninety Limosa harlequin frogs (Atelopus limosus) bred in human care are braving the elements of ...Read More →
The extinction crisis is far worse than you think. In all of Earth’s history, there have been five mass extinction events. You can see them charted here. Now, we’re on the verge of the sixth extinction. And three-quarters of all species could vanish. Imagine three out of four species that were common are gone. This is the first time humans have caused anything like this.Read More →

THE ALBINO MINE, Venezuela — The 12th time Reinaldo Balocha got malaria, he hardly rested at all. With the fever still rattling his body, he threw a pick ax over his shoulder and got back to work — smashing stones in an illegal gold mine.
As a computer technician from a big city, Mr. Balocha was ill-suited for the mines, his soft hands used to working ...Read More →
A decade after a judge ordered tobacco companies to acknowledge the dangers of low-tar cigarettes, they continue to dispute the scientific consensus.
In a landmark ruling nearly a decade ago, a federal judge ordered tobacco companies to stop lying.
After listening to 84 witnesses and perusing tens of thousands of exhibits, U.S. District Judge Gladys Kessler of the District of Columbia took a year to write a 1,652-page opinion detailing the companies’ elaborate strategy to deny ...Read More →

When you hear about antibiotic use in agriculture it is almost always about the kind of routine everyday use in livestock that the Food and Drug Administration is trying to eliminate. But there’s another type of antibiotic use in agriculture. It may be less known, but it’s poised to generate just as much controversy: spraying the drugs on citrus trees.
Florida’s Department of Agriculture and Consumer Services has applied to the U.S. ...
