Patrick Dougherty: Rooted in Nature
Patrick Dougherty’s art career is rooted in his fascination with nature and primitive building techniques.
Born in Oklahoma in 1945 and raised in North Carolina, Dougherty first pursued traditional academics, earning degrees in English and Health Administration. However, his return to North Carolina to study art history and sculpture sparked a desire to create works of art utilizing natural materials, particularly tree saplings. Combining this desire with his carpentry skills, Dougherty began crafting unique, large-scale sculptures that organically blend into their environments.
Jacques Régnière: Budworm to BioSIM
Jacques Régnière, born in Quebec City, has dedicated over four decades to advancing our understanding of forest pests and protecting our global forests. Earning his bachelor’s degree in biology from Laval University and a Ph.D. in insect ecology and biomathematics from North Carolina State University, Régnière began his career at the Canadian Forest Service in 1980, where he served until his retirement in 2024.
Throughout his distinguished career, Régnière focused on pressing issues in forest ecology, notably the population dynamics of the spruce budworm, mountain pine beetle, and spongy moth. His work in quantitative ecology has influenced pest management practices and provided a better understanding of climate change’s impact on invasive species and forest health.
Purdue launches new AI-based global forest mapping project
Purdue University’s Jingjing Liang has received a two-year, $870,000 grant from the World Resources Institute to map global forest carbon accumulation rates.
“To accurately capture the carbon accumulation rates of forested ecosystems across the world has always been a challenging task, mostly because doing so requires lots of ground-sourced data, and currently such data are very limited to the scientific community,” said Liang, an associate professor of quantitative forest ecology and co-director of the Forest Advanced Computing and Artificial Intelligence Lab.
“This task is considerably more challenging than mapping carbon emissions from forest loss,” said Nancy Harris, research director of the Land & Carbon Lab at the World Resources Institute, a nonprofit research organization based in Washington, D.C. “With emissions, there’s a clear signal in satellite imagery when trees are cut, leading to a big drop in forest carbon stocks and a relatively abrupt pulse of emissions to the atmosphere. With sequestration, forests accumulate carbon gradually and nonlinearly.”
The Role of Technology in Forest Management
In Brazil’s Pará region, new roads are cutting through the pristine Amazon rainforest, opening up once-untouched areas to human activities. Expansive stretches of lush greenery are vanishing at an alarming pace, yielding to barren patches and freshly cleared land.
Meanwhile, far into space, the European Space Agency captures high-resolution satellite images of the region that unveil an important pattern: deforestation occurs predominantly near these newly constructed roads.
Back in 2016, it sparked a question: what if there were a tool to monitor these roads and forecast potential deforestation areas? Not long after PrevisIA was born.
In 2021, Microsoft with Vale Fund and the Amazon Institute for Man and the Environment (Imazon) developed a new AI tool called PrevisIA, to predict deforestation hotspots in the Amazon. Using satellite imagery from the European Space Agency and an algorithm developed by Imazon, the tool produces heat maps showing the most exposed conservation areas, Indigenous lands, and other settlements, along with rankings for states and municipalities.
Single-Photon Lidar
The Canadian Institute of Forestry in partnership with the Canadian Wood Fibre Centre and other organizations are currently researching the potential of single photon lidar for Ontario’s
Enhanced Forest Resource Inventory (EFI) at the Petawawa Research Forest (PRF).
What is Lidar?
A lidar (light detection and ranging) sensors will emit light pulses that will reflect or bounce off objects, such as standing trees or the ground. This measures the time of return and the distance that each pulse travels. The result is highly detailed 3-D point clouds of the forest environment.
Dr. Willy Burgdorfer: One Tick at a Time
Dr. Willy Burgdorfer, born on June 27, 1925, in Basel, Switzerland, is known for transforming the understanding of tick-borne illnesses.
Burgdorfer pursued his undergraduate and doctoral studies in parasitology and tropical bacteriology at the University of Basel – where he first developed his fascination with ticks while studying how these arthropods transmitted spirochetes that caused relapsing fever. In 1951, Burgdorfer moved to the United States for a fellowship in Montana at the Rocky Mountain Laboratories (RML) – a National Institute of Health biomedical research facility for vector-borne diseases, such as Rocky Mountain spotted fever, Lyme disease and Q fever.
What Does Lyme Disease Do to Your Body?
What exactly is the connection between a tick bite and lyme disease?
While we’re not sure exactly where and when the disease originated, we do know a lot about how it works, its signs, its symptoms in humans and dogs, how it’s spread and its treatment.
Check out this video by Seeker to learn all about what lyme disease does to your body.
Tick-ing Time Bomb: The Expanding Threat of Tick-Borne Diseases
Urbanization, resistance to pesticides, and, most critically, climate change are creating ideal conditions for global tick proliferation. As these 8-legged bloodsuckers expand their territories, the world should expect a corresponding rise in Lyme disease, spotted fever, Crimean-Congo hemorrhagic fever, tick-borne encephalitis, and other conditions that infect humans, pets, and livestock.
“This is an epidemic in slow motion,” a Centers for Disease Control (CDC) tick expert and research, biologist told the Associated Press.
Ticks live on every continent except Antarctica, and while estimates of annual tick populations vary, the scientific community agrees that their numbers are growing. Researchers also are unanimous that arachnids pose an increasing health risk as mild winters and longer summers associated with global warming kill off fewer individuals, give them longer to develop and feed, and make higher elevations and northerly latitudes that previously were too intemperate or elevated more hospitable.
Lyme Disease Quick Facts
Lyme disease is one of the fastest growing infectious diseases in the country and one of the most difficult to diagnose. Experts in the medical and scientific community, as well as key legislators, have deemed Lyme disease an epidemic … a national public health crisis … and a growing threat.
300,000 people are infected with Lyme disease each yearAt least 300,000 people are infected with Lyme disease each year
New tick-borne diseases are emerging … the number of tick endemic regions is growing … the tick population is increasing … and, the number of people infected with Lyme disease is steadily rising.
The Centers for Disease Control and Prevention (CDC) report that at least 300,000 people are infected with Lyme disease each year in the United States. That’s 25,000 new cases per month. Twenty-five percent of those patients are children, ages 5 to 14.

Thomas Dambo: The Master of Upcycled Urban Sculptures
Thomas Dambo, born in Odense, Denmark in 1979, grew up in a creative and communal environment. From a young age, Dambo was encouraged to explore his creativity, building his first wooden box for his brother’s pacifier and scavenging materials to construct massive fortresses with his friends.
As a teenager, Dambo delved into street art, urban exploration, and graffiti. His passion for urban culture and hip-hop led him to become a beatboxer, touring with Norwegian rapper Skranglebein. In 2004, he formed the hip-hop super crew Fler Farver with his younger brother and friends, releasing nine albums and gaining significant recognition in the Danish underground hip-hop scene.
