The Purdue Herbaria

An insider’s look at a university collection so valuable, the professor who built it once stole it back.

The earliest herbarium—a collection of plant samples preserved for scientific study—dates to 16th-century Italy, when the Bologna physician and botanist Luca Ghini (1490–1556) sought to make plant material available to his students in winter when the plants were dead or dormant.

The specimens were flattened between two pieces of paper to remove moisture. Once dried, they were mounted on paper sheets with notations on the plant’s name, where the plant was gathered, and any distinctive features. The pages were bound into volumes to enable transport from one location to another, thus making plant material from faraway places available indefinitely.

The Stewarts at Westwood

Robert Bruce Stewart (HDR M’68), known as R.B., joined the Purdue University staff as controller in 1925. At that time, Purdue enrolled 3,000 students, the physical plant was worth $3 million, and the endowment totaled $340,000.

Stewart, who went on to become the university’s first vice president and treasurer, is credited by many with influencing the character and growth of Purdue University. He spent 36 years building the university both fiscally and physically.

Geochemist Marissa Tremblay ’12 analyzes Antarctic rocks to unravel Earth’s climate chronology and predict the planet’s future environment

A geologic field excursion to Death Valley during spring break her first year at Barnard set Marissa Tremblay ’12 on course to becoming a scientist. She entered college intending to pursue a law degree, but stepping foot on that vast, desolate desert landscape marked with sand dunes ignited a curiosity to uncover the stories in stones.

50 Years of Wolf Park

Founded by Purdue ethologist Erich Klinghammer in 1972, Wolf Park began as an experiment to study wolf behavior. The pioneering research conducted there over the past 50 years contributed to a better understanding of the apex predator and facilitated its reintroduction into the wild.

Twenty Years After 9/11 Longhorn Reflects on the Unexpected Detour—and the Subsequent Broadway Show—that Altered His Life’s Trajectory

On the morning of September 11, 2001, Kevin Tuerff and his then-partner, also named Kevin, were on an Air France flight bound for New York City. The couple had just wrapped up a European vacation and they were eager to get home. A sudden drop in elevation over the Atlantic Ocean was the first sign that something was amiss. Then came an announcement from the cockpit.

New genetic testing available through ADDL will help dog breeders eliminate specific diseases

Research findings by genetic scientists in the Purdue University College of Veterinary Medicine have the power to eradicate specific genetic diseases within certain dog breeds. Testing for the genetic mutations will be offered by the Animal Disease Diagnostic Laboratory (ADDL) at Purdue. As the first such tests offered to the general public for three new canine genetic diseases, these screenings will enable breeders to identify which dogs are carriers for a disease and could possibly pass it on to offspring. By ensuring two carriers are not bred together, the disease can be halted before it spreads throughout the breed.

Boosting Brown Fat to Combat Obesity and Type 2 Diabetes

Treatment in development by Adipo Therapeutics holds promise for millions who struggle with weight loss and blood glucose control

Eat less. Exercise more. It sounds so simple. But if it were that simple, America wouldn’t be facing the dual epidemics of obesity and diabetes.

Adipo Therapeutics, a Purdue Research Foundation-backed startup, is developing a unique treatment approach that turns bad fat into good fat. This disruptive nanotherapeutic delivery could provide a safe and effective way to treat obesity and Type 2 diabetes.

Enhancing Well-being and Boosting Productivity in Dairy Cows

Indiana is home to more than 800 dairy farms, generating an average of nearly $700 million in direct farm income annually, according to the Indiana State Department of Agriculture. The average dairy cow produces around 2,320 gallons of milk per year, but metabolic disorders can affect that output as well as animal well-being.

Purdue University Cytometry Laboratories Aim to Develop Portable Toxin and Pathogen Detection Device

An estimated 48 million people in the United States experience foodborne illness each year, according to the Centers for Disease Control and Prevention. Of those, 128,000 cases require hospitalization and 3,000 result in death. A 2010 report published by the Produce Safety Project estimated that foodborne illnesses cost $152 billion in medical expenses, lost productivity and business, lawsuits and compromised branding.

First-of-its-kind Vector-borne Disease Panel Screens for 22 Different Pathogens in a Single Test

A diagnostic panel developed by researchers in the Purdue University College of Veterinary Medicine will enable its Animal Disease Diagnostic Laboratory (ADDL) to screen for 22 different vector-borne pathogens in a single test. The panel, designed to be used on cats and dogs, is the only test of its kind and now is available to clients of the ADDL.

New methodology may one day map forests around the world

What if we could map every tree on the planet?

It’s a question that drives the work of Joshua Carpenter (MS’20), a PhD student and researcher in the Geospatial Data Science Lab supervised by Jinha Jung, Assistant Professor of Civil Engineering.

Just as the field of precision agriculture uses high technology sensor and analysis tools to measure the growth and health of fields of crops, Carpenter is developing methodologies that could one day be similarly applied to forests around the globe.

Mopping produces pollutants similar to vehicle emissions

The fresh-scented products used to clean our homes and offices come with risks to our respira-tory health. The chemicals used to create scents such as lemon and pine pollute indoor air with nano-sized particles in similar ways that motor emissions affect the air we breathe outdoors, according to a new study published in the journal Science Advances.
