Jerry Franklin: The Father of New Forestry
Jerry Franklin, known as the “Father of New Forestry,” has made his mark in forest management for integrating ecological and economic objectives. His approaches, which faced skepticism initially, have become the standard in both environmental and timber industry circles.
Franklin began his career as a research forester for the USDA Forest Service in 1959. His early work included long-term experiments on forest ecosystems, particularly old-growth forests.
Chimpanzees May Self-Medicate With Plants, Using the Forest as a Pharmacy
Chimpanzees may be using the forest like their own personal pharmacy. When they’re sick, the primates appear to seek out and eat plants with antibacterial and anti-inflammatory properties, according to new research.
Observers have long suspected that chimpanzees use plants to self-medicate. Now, a new paper published last week in the journal PLOS ONE offers more evidence in support of this idea.
Researchers followed two groups of wild chimpanzees through Uganda’s Budongo Forest for eight months. They recorded what the animals ate, as well as whether they were sick—which they determined by checking their feces for parasites, testing their urine for elevated levels of immune cells and looking for wounds.
What is a Healthy Forest?
Healthy forests are beneficial for people and wildlife.
When forests are healthy, they produce enough food, water and shelter to support local wildlife, clean the air, reduce erosion into nearby streams and lakes, and are less susceptible to large-scale high-severity wildfires.
But what does a healthy forest look like?
Rogan Brown: The Science of Paper
Rogan Brown is an Anglo-Irish artist notable for his intricate paper sculptures that beautifully intertwine art and science. Drawing inspiration from the microscopic to the monumental—microbiology, botanical forms, geological structures, and marine ecosystems—Brown meticulously handcrafts and laser-cuts complex three-dimensional artworks. His pieces surpass mere representation, merging scientific accuracy with surreal artistic flair.
Shiuly Khatun: Dengue Warrior
Shiuly Khatun is a Field Supervisor at the Dhalpur Aalo Clinic in Dhaka, Bangladesh, where she manages and coordinates the clinic’s operations. Her daily responsibilities are vast and critical, ranging from mapping areas and dividing work for community volunteers to conducting health sessions and overseeing satellite clinic activities.
Dengue fever, once confined to the tropics, now threatens the U.S.
Climate change is expanding the habitat of the mosquitoes that carry the disease, allowing them to spread further north.
Meg Norris was traveling in Argentina in April when the first signs of dengue fever hit her. The weather in Salta, just south of the Bolivian border, was warm, but Norris, a 33-year-old from Boulder, Colorado, zipped a fleece sweatshirt around her body to stop herself from shivering.
“I thought it was sun poisoning,” she said.

The Rise of Dengue: A Global Perspective
Around the world, dengue is considered the most common viral disease transmitted by mosquitoes that affects people. According to the World Health Organization (WHO), the disease is now endemic in more than 100 countries. In the first three months of 2024, over five million dengue cases and over 2000 dengue-related deaths were reported globally. The figures so far project that 2024 could be even worse than 2023, with the regions most seriously affected being the Americas, South-East Asia, and Western Pacific.
In the Americas, there were 6,186,805 suspected cases of dengue reported in the first 15 weeks of 2024. To put this into perspective, according to the Pan American Health Organization (PAHO), this figure represents an increase of 254% compared to the same period in 2023. Of these cases 5,928 were confirmed and classified as severe dengue.
Mary Beth Heffernan: From the Studio to the Hospital Ward
Mary Beth Heffernan, a Los Angeles based artist, brings together corporeality and imagery through various media. Her work examines deep questions about how bodies and their experiences are represented in digital and physical forms.
One of Heffernan’s most notable projects, the PPE Portrait Project, began in 2014 to humanize the protective gear of Ebola workers in Liberia. By placing portraits on protective equipment, the project helped mitigate fear and foster connections between healthcare workers and patients. The initiative gained international attention and was adapted for COVID-19 response, impacting healthcare settings worldwide, including major institutions like Stanford Medical School and Massachusetts General Hospital.
Dr. Samuel Katz: The Man Who Helped Conquer Measles
Dr. Samuel Katz made monumental contributions to pediatric health and vaccinations before his passing on October 31, 2022, at the age of 95. His career was proof that one dedicated individual can have a profound impact on global public health.
Born on May 29, 1927, in Manchester, NH, Samuel Katz initially studied journalism at Dartmouth College, but quickly switched to medicine after a stint in the Navy during World War II. Moving on to his medical studies at Harvard Medical School, he was drawn into the world of virology under the tutelage of John Enders, a Nobel Laureate. This collaboration marked the beginning of Katz’s lifelong battle against infectious diseases, which included the development of the measles vaccine.
