Preserving habitats and encouraging biodiversity does wonders for plant and animal life, giving them room to thrive without human interference. In recent years some scientists have wondered if biodiversity might also help humans, protecting us from infectious diseases that spread from nonhuman animals to people
Ecologists shared ideas and research about the Ebola virus at a meeting in Athens, Georgia. Cary's Barbara Han talked about methods scientists are developing that would identify likely wildlife carriers of filoviruses, a kind of virus related to rabies virus which includes Ebola, Marburg virus and some other deadly species.
Explore the ecology of Lyme disease with Rick Ostfeld, a disease ecologist at the Cary Institute. For more than twenty years, Ostfeld and his research team have been investigating how environmental conditions influence the spread of tick-borne illness.
Between 1346 and 1353 the Black Death killed over a third of Europe's population. It took 150 years for the continent to recover. The disease was so devastating that it changed the social order, as a scarcity of labour led to higher wages for the survivors, hastening the demise of feudalism.
Using a computer to predict an infectious disease outbreak before it starts may sound like a bit of Philip K. Dick sci-fi, but scientists are coming close. In a new study, researchers have used machine learning—teaching computers to recognize patterns in large data sets—to make accurate forecasts about which animals might harbor dangerous viruses, bacteria, and fungi.
Machine learning can pinpoint rodent species that harbor diseases and geographic hotspots vulnerable to new parasites and pathogens. So reports a new study in the Proceedings of the National Academy of Sciences led by Barbara A. Han, a disease ecologist at the Cary Institute of Ecosystem Studies.
Around the world, millions of frogs, toads, and salamanders are dying from two emerging diseases. The first plague appeared in the 1990s, and is so deadly to amphibians that it is causing what has been described as the most spectacular loss of vertebrate biodiversity due to disease in recorded history.
Dengue fever and chikungunya are transmitted to humans by two species of mosquitos, Aedes aegypti and Aedes albopictus. There are no vaccines for these viral diseases and while not often fatal, they can disable victims with painful symptoms for weeks or months.
Podcast A new study in New York reveals that ticks are more likely to be infected with several pathogens, not just the bacterium that causes Lyme disease. The ticks for the study were collected from Dutchess County.
To find out how to steer clear of Lyme disease during "picnic season" - a time when people are more likely to pick up ticks - the National Science Foundation spoke with NSF-funded disease ecologist Rick Ostfeld of the Cary Institute.
While bloodsucking ticks can lay waste to a moose and infect humans with devastating diseases, the tiny parasites and the bacteria they carry have no apparent effect on one wee woodland creature: the white-footed mouse.
Another public health challenge the National Climate Assessment will explore is the likelihood that diseases native to other geographical areas will migrate to the United States as climate changes alter ecosystems.
Warming temperatures and increased extreme weather events such as drought, rainstorms and flooding, contribute to the nation's changing disease map, experts say. USA Today reports on this trend and how it has impacted the spread of various diseases including tick-borne illnesses.
Initially, Rick Ostfeld’s work at the Cary Institute focused on how small mammals shape forests. Early on, he noticed a unique relationship among mice, black-legged ticks, and the bacterium that causes Lyme disease.
A new paper from members of the HEAL (Health & Ecosystems: Analysis of Linkages) consortium delineates a new branch of environmental health that focuses on the public health risks of human-caused changes to Earth’s natural systems.
Given the 300,000 new cases of Lyme disease a year in the US reported by the CDC, it is understandable that health organizations and local governments in this country are extremely anxious to develop a broader, more effective tick-borne diseases control strategy.
In the Northeast, the black-legged ticks (Ixodes scapularis) that spread Lyme disease also infect people with other maladies, among them anaplasmosis, babesiosis, and – as a new paper in the journal Parasites and Vectors reports – Powassan encephalitis.
The Asian tiger mosquito is yet another invasive species that has taken hold in the United States. It arrived here in 1985 in a shipment of tires imported from Asia. This little mosquito is an aggressive human biter capable of transmitting diseases.
Video Three members of Congress joined forces with a Lyme disease advocacy group to host a forum to discuss the fight against tick-borne diseases. As a panelist, Cary's Rick Ostfeld shared his research and insights.
There are few creatures more deadly than the tiny Aedes aegypti mosquito, which transmits malaria, dengue fever and other infectious diseases. Malaria is one of the world’s great killers, claiming about 800,000 lives each year. We can, of course, drain wetlands and spray large areas with insecticides to kill these mosquitoes.
For many years, oaks in the Northeast were prolific acorn producers. The 2010 crop was record-breaking—many will recall getting hit with acorn rain or slipping on acorns underfoot. Last fall, however, acorns were scarce.
Dengue (pronounced DEN-ghee) fever is caused by a virus spread by mosquitoes. It was formerly called "break-bone fever" because it causes excruciating pain to the muscles and joints of its human victims.
