Tracking the traffic between our cells Nov 21, 2023 9:30 am314 views We adjust a lens, and a bright constellation swirls into view – points of colored light hung against a deep-hued backdrop. They are not stars, but extracellular vesicles: tiny packages of molecular cargo in nanosized lipid carriers, released by all cells in the body. We are launching a new project with the goal of not only visualizing EVs in living tissue, but also tracking their dynamics. We have been named 2023 Allen Distinguished Investigators by the Paul G. Allen Family Foundation for this purpose. Renovating historic Altgeld Hall Nov 20, 2023 12:45 pm480 views The slabs of sandstone that make Altgeld Hall one of the most recognizable buildings on the University of Illinois Urbana-Champaign campus have been covered in scaffolding for months. But the results of the renovation work going on there are apparent, as the dark gray stone is restored to a pinkish hue. The work is part of a multiphase project that includes exterior and interior restoration of the building. ‘CETACEAN’ performance shows connections between whales’ environment and humans Sep 20, 2023 12:00 pm919 views Shafts of sunlight are coming through the skylights of the Stock Pavilion on the University of Illinois Urbana-Champaign campus, illuminating swirls of dust stirred up as several people standing on the dirt floor uncoil ropes, pulling them taut and twirling them in circles like lassos. It looks like the setting for a rodeo, but this is a nautical environment.“CETACEAN (The Whale),” the latest multimedia performance in “The Unreliable Bestiary,” tells stories about eco-anxiety and resilience in adjusting to changing conditions. Volunteers maintain ‘first gallery’ of flowers outside Krannert Art Museum Sep 18, 2023 11:00 am797 views It’s one of the hottest days of the summer, but a dozen people have gathered with their water bottles, sun hats and gardening tools in front of Krannert Art Museum at the University of Illinois Urbana-Champaign. They're starting early in the morning, before it gets even hotter, amid blooms of pink, purple, yellow, orange and white. They're clipping the spent flowers from zinnias and the dead leaves from day-lilies, weeding and watering. Changing police culture with stories of wrongful convictions Jun 8, 2023 8:00 am1616 views I’m in a room with more than 100 police recruits and I can’t believe what I’m hearing. The future police officers are learning about the devastating consequences of criminal prosecutions gone wrong. These aren’t just abstract stories. More than a dozen exonerees are here to share their stories with the police recruits. Following in the footsteps of early 20th century naturalist Elizabeth Kerr Jun 5, 2023 8:00 am749 views Trek through Colombia with graduate student Juliana Soto, who, with her all-female team of Colombian ornithologists, revisits landscapes to study and document the birds of the region. In preparing for the expedition, Soto discovered the work of naturalist Elizabeth Kerr, who in the early 20th century collected wild bird specimens in Colombia for the American Museum of Natural History. Preserving the sound of the Altgeld Chimes May 12, 2023 9:30 am2391 views Early on a sunny Sunday morning, the chimes tower in Altgeld Hall is filling up with people. Students climb the steep staircase to the tower, several of them carrying snacks. They are all chimes players who will perform for a recording of chimes music. 'Blind Field Shuttle' brings a new perspective to campus walk May 3, 2023 8:45 am410 views University of Illinois Urbana-Champaign staff and students took part in the participatory artwork “Blind Field Shuttle” by artist Carmen Papalia, which offers participants the opportunity to explore the world without sight. Preserving Illinois forests, one landowner at a time Apr 28, 2023 10:00 am555 views Go Behind the Scenes with U. of I. Extension forestry and research specialist Christopher Evans, who leads a training program for landowners who want to learn how to maintain healthy forests. Returning to Illinois theatre to direct, mentor students Apr 25, 2023 1:30 pm800 views Tyrone Phillips, an Illinois theatre program alumnus and the artistic director of Chicago’s Definition Theatre, returned to direct students in a play this spring. Nurturing a tropical paradise in the heart of the Midwest Mar 10, 2023 8:00 am2514 views Lexi Gomez is knee-deep in a pond when I first see her in the U. of I. Plant Biology Greenhouse and Conservatory. A fifth-year senior who will graduate this semester, Gomez dips a net in the dark water to clear the pond of debris fallen from the lush jungle of tropical plants that looms above. She attacks the work with gusto. Teaching generations of students about outbreaks – with art Jan 26, 2023 8:30 am1081 views Most people don’t visit the health department to view student art, but here we are, in the busy main hall of the Champaign-Urbana Public Health District. We are wearing face masks, reading artist statements and reviewing more than a dozen visual and digital explorations of influenza, respiratory syncytial virus, COVID-19 and – the trickiest of all health topics – human behavior. Nurses and dental assistants whiz by with young patients. People walk by to pick up birth certificates. Two kids sit in a corner and play with one of the art pieces. It’s obvious this isn’t just an art show. It’s an end-of-term presentation designed by students in my evolutionary immunology class for students in kindergarten through the eighth grade. These creative works are meant to show the youngsters how to prevent the spread of respiratory infections in the community. These kids are using the art exactly the way it was intended. Using a 19th-century hand press to teach history of printing technologies Dec 8, 2022 9:00 am1245 views Three students gather around an old iron letterpress at the Champaign-Urbana Community Fab Lab, preparing to make a print using 19th-century technology. The press requires all three students to operate it. Bringing a game to life through dance Nov 4, 2022 8:30 am1104 views I'm in my little sister's room, where I've grabbed her Bop It! toy from her desk. I will use this toy to structure the dance I'm choreographing. I have my little black notebook and favorite black pen nearby. My phone leans against my computer, ready to record. I pull the Bop It! lever to start the game. A marvelous morning of migratory bird banding Oct 25, 2022 8:00 am1035 views My alarm is going off as I quietly, yet eagerly, get out of bed at the dark and early time of 4 a.m. Today, I get to do something that I love and that also benefits bird conservation. I arrive just before dawn at the U. of I.’s Phillips Tract, a former farm that is now a 130-acre natural area just east of Urbana and is used for scientific research and student training. I unlock the gate, park and gather the supplies I keep on site. Then I wait for the volunteers to arrive. The team today is a dedicated mix of staff, graduate students and undergraduates – all of whom are committed to helping capture, band and monitor the birds that use this site. Vivifying ikebana: Japanese flower arranging Oct 21, 2022 8:15 am745 views Sitting at the long covered tables in the heart of Japan House, I close my eyes. All 18 of us do. We are students in the Japan House class Ikebana: The Art of Japanese Flower Arrangement. Professor Kimiko Gunji is introducing our sixth ikebana arrangement, and this is our first step. My socked feet glide on the smooth hardwood floor as I sit in silence and think. What kokoro – emotion, essence, idea – do I want to convey? Learning from chickens Oct 19, 2022 8:00 am867 views The first thing I notice when we step through white double doors of the growers’ house is that every one of the 1,200 or so chickens in this enormous room has stopped whatever it was doing to stare at us. A few of the birds step closer, peering at our legs as if they want to peck our shoes. But they don’t. They’re just curious. Chickens, I realize, are gawkers. Bringing an enslaved potter's story to the Met Oct 17, 2022 8:00 am773 views As we climb the mountain of stairs that leads to the Metropolitan Museum of Art and step inside, I’m struck by the scale and grandeur of what lies before me and the complexity, beauty and discourse it offers. I want to take in the entire museum, but I am most excited to see the stoneware jug that I first encountered while excavating in 2011. This jug is part of the museum’s “Hear Me Now: The Black Potters of Old Edgefield, South Carolina” exhibition. Exploring an ancestral Maya neighborhood Sep 9, 2022 9:00 am1874 views We stand in the open fields of Spanish Lookout, a modernized Mennonite farming community in Central Belize, looking at what remains of ancestral Maya homes after years of plowing. White mounds, the remnants of these houses, pock the landscape as far as the eye can see, a stark reminder of what existed more than 1,000 years ago. The collapsed buildings look like smudges on an aerial photograph, but as archaeologists, we get to see them up close. With enough excavation and interpretation, we can eventually make sense of how these dwellings functioned in the deep human past. Searching the Texas brushland for a rare, temperamental plant Aug 18, 2022 9:30 am1083 views The author and her colleagues search a South Texas scrubland for the federally endangered Zapata bladderpod, Physaria thamnophila. This rare endemic plant, a member of the mustard family, is named for the region and is found in only two counties in the United States. Waiting for the sun to set to find a rare bird Jun 30, 2022 9:00 am2181 views When most people are just getting home from their workdays, I’m about to start mine. I am a researcher studying the breeding behavior of the Eastern whip-poor-will (Antrostomus vociferus), a cryptic bird that is primarily active after sunset as it forages on the wing for moths. So – for the summer, at least – I also am nocturnal. Rescuing ancient Maya history from the plow Jun 22, 2022 8:45 am940 views Things have changed since I was last in Belize in 2018, when I excavated the ancestral Maya pilgrimage site Cara Blanca. Thousands of acres of jungle are gone, replaced by fields of corn and sugarcane. Hundreds of ancestral Maya mounds are now exposed in the treeless landscape, covered by soil that is currently plowed several times a year. Before the COVID-19 pandemic, I was awarded a three-year National Science Foundation grant to conduct a salvage archaeology project here in Belize. The goal is to collect as much information as possible before the mounds are plowed away. Saving an endangered breed of donkey Jun 3, 2022 8:00 am2733 views Nothing I’ve read about the Baudet du Poitou donkeys prepares me for my first sight of them. They are girthy, with massive round bellies and oversized ears that swoop forward and back, sometimes independently of one another. They are covered in thick hair that hangs in shaggy tufts, “like mammoth fur,” says my companion on this adventure in equine medicine, Public Affairs senior photographer Michelle Hassel. We’re here today with veterinarian and Ph.D. student Dr. Giorgia Podico to observe these exotic animals and check on their reproductive status. Podico is part of a team that is trying to impregnate these donkeys, which are endangered and in need of conservation. Making meat much more than a meal May 18, 2022 8:00 am2020 views The grills are already fired up as I approach the Meat Science Laboratory on the U. of I. campus. It’s midmorning on a spring day that’s chillier than it should be. Well-worn charcoal and gas grills are stationed in a wide arc on a lawn flecked with violets. In front of each grill stand three students for whom eating burgers for breakfast is now commonplace. Building a traditional Japanese boat Apr 6, 2022 12:15 pm1731 views Japan House offered a Japanese boatbuilding apprenticeship, where students worked with boatbuilding expert Douglas Brooks to build a traditional riverboat in six days. Creating an escape room experience Dec 10, 2021 8:30 am2266 views Students in Fine and Applied Arts and informatics learned how to create an immersive environment and to build puzzles to challenge the players and reinforce the story. Building back a tiny piece of prairie Nov 15, 2021 8:00 am1848 views Early November may not be an optimal time to visit a tallgrass prairie in central Illinois. But if you know what to look for, as my two guides do, it’s as good a time as any. Despite recent heavy rains, the prairie looks as dry as a skull. Grass and flower stalks rattle in the cold breeze, and each plant appears to sport its own special array of desiccated seeds, leaves and flower heads. The ground is still damp but the tops of the plants are crispy. I’m here with Fred Delcomyn and James Ellis, the authors of “A Backyard Prairie,” a book about Fred and Nancy Delcomyn’s personal project, a 3-acre swath of prairie that they began installing near their home in 2003 and have nurtured ever since. Staging a threatening encounter at a blackbird nest Oct 7, 2021 8:15 am1292 views It’s early morning, about 6 a.m. A light fog has settled over the marsh. I park my car, step out and double-check my backpack for all the necessary equipment before heading out. After a short walk on a narrow paved path, I veer into the unmarked marsh. I’m here to study how red-winged blackbirds respond to the vocalizations that signal nearby nest parasites called brown-headed cowbirds. Exploring the remnants of an ancient forest Sep 2, 2021 8:00 am2530 views At first glance, Trelease Woods looks like any other central Illinois woodland. There’s a well-worn track inside its fenced eastern edge, and the forest floor is littered with twigs and branches. But as I walk along the path with my companions, I notice that some of the trees are bigger than any I’ve seen in this area. Hunting a creature that hunts me Aug 20, 2021 8:00 am2441 views It’s a sweltering summer afternoon. I’m pushing aside tree limbs and crunching leaves to get back to the trap that I baited two hours ago with dry ice to attract ticks. When I get closer, I can see a gossamer mist hovering over a bright white cloth in the dark underbrush. Dry ice “sublimates” in the open air, going from a solid to a gaseous state. It gives off a vapor of carbon dioxide gas that’s denser than the air, mimicking the breath of a tick host resting on the ground. In pursuit of Indiana bats Jun 22, 2021 8:00 am828 views An hour before the sun goes down, my colleagues and I arrive at our site: a human-made pond in the middle of the forest. The high-pitched croaking of Cope's gray treefrogs greets us as we get out of our truck. Surrounded by trees and full of salamanders, these ponds are an essential water resource for our forest-dependent bats. We do a brief survey of the site, then set up our mist nets around the pond’s perimeter. We’re hoping to catch our target species – the Indiana bat, Myotis sodalis. Taking a cicada road trip May 27, 2021 8:00 am1227 views CHAMPAIGN, Ill. – A tough semester and an even tougher year have just ended. I need a break. I’m fully vaccinated and want to escape the yearlong lockdown. And I’m an entomologist. What do I do? I grab my best friend, also an entomologist, and we hit the road, of course. This is the year of my people’s “Woodstock.” Catching bats for conservation May 18, 2021 8:00 am818 views The sun just dipped below the horizon and the warm early spring air mixes with the stone-chilled currents flowing out of the mine entrances. The nets are all hung and now we are just waiting for the bats to show up. This is my first mist-netting trip, but I have been warned this will not be a typical experience. Pondering a university's ecological impact Apr 22, 2021 8:00 am812 views Earth Day has one science writer pondering how much research conducted at the University of Illinois Urbana-Champaign has direct ecological implications. Connecting a virus to cancer – in sea lions Mar 31, 2021 8:00 am607 views I distinctly remember the first day I saw the images proving our hypothesis about the connection between a herpesvirus and urogenital cancer in wild California sea lions. Our research team was the first to use a revolutionary technique to probe preserved cancerous tissue from marine mammals as we looked for signals of specific viral genes. And we found them: Wherever there was tumor, there also was a strong signal of multiple cancer-promoting viral genes, called oncogenes. There were no viral genes in the adjacent cancer-free tissue. This meant that the virus clearly played a role in cancer development and was not merely a bystander in the animals’ reproductive tracts. Hunting Goodenough Days Nov 30, 2020 9:15 am550 views HUNTING GOODENOUGH DAYS aptly describes what I am doing during the isolation of 2020. These words are surnames found among the 7,000 headstones that I have photographed during my travels to cemeteries seeking new names that are parts of speech – words that I can use to create poetry for my visual books that investigate language, history and life’s events. Adjusting to these 'ever-changing times' Nov 24, 2020 8:00 am895 views My mask keeps my face warm as I make my way to the Wildlife Veterinary Epidemiology Laboratory this cold November morning. Campus is starting to empty out as students leave for the holidays. However, with cases of COVID-19 increasing again, many students may not return until next semester and many others will be isolating in their homes. Back in March, I worked remotely when the pandemic shut campus down, and since early summer, I have been working in person again. After the holidays pass, I hope we won’t have to give up our time in the laboratory to do virtual work alone. Finding one elusive bird Oct 16, 2020 8:15 am1370 views It’s hot and my shirt is sticking to my back. I part scrubby marsh vegetation with one hand and shield my face with the other. Hiking along the margins of Illinois’ only open-water quaking bog, I’m carrying five liters of swamp water in bottles in my backpack, my samples sloshing with each step. Collecting wetland water samples is far from glamorous. My feet are wet, my legs caked in mud, and I frequently swat at hordes of mosquitoes as I hike, sometimes with as much as 10 liters of water in my pack. I’m not interested in the water; rather, if all goes well, I will find my samples contain the DNA of mysterious marsh birds, called rails, that breed and migrate through Illinois wetlands. Unearthing a fossorial snake Oct 12, 2020 9:00 am2326 views To the naked eye, it might appear as though I’m standing in a prairie oasis. Pockets of bright yellow goldenrod bring vibrancy to the sea of towering grasses. There’s not a soul in sight to spoil the serenity. A lone red-tailed hawk scouring the landscape from the top of a dead oak tree is my only companion. It’s not hard to imagine the entire region looking like this prior to European settlement, expanding miles and miles without interruption. I made the two-hour drive from Champaign to this tiny, fragmented prairie to search for an uncommon snake. Celebrating our diversity Sep 28, 2020 8:15 am1216 views NOTE: This post describes events prior to the coronavirus epidemic. It is snowing again, and I turn to look through the bus window as it slowly pulls into the final stop. I hide my face in my scarf, hoping to stop the cold air sneaking in. It has been almost six years since I moved to the Midwest from Taiwan, but I still cannot deal with winter and snow. Once off the bus, I follow footprints to the Wildlife Veterinary Epidemiology Laboratory and push open the glass door. Following the sounds of prairie cicadas Sep 24, 2020 9:30 am1540 views When I arrive at the Loda Cemetery Prairie Nature Preserve, Katie Dana is already out there. She’s wearing knee-high boots to ward off chiggers and ticks, and she’s carrying an insect net. Dana is on the prowl for cicadas: the loudest insects on the planet. On this hot summer day, they do not disappoint. The males are in full chorus. Gathering data to save a rare turtle Aug 13, 2020 9:00 am1744 views We are never more conscious of the summer sun than while struggling to unpack a trap full of turtles, watching with resignation as the wind slowly drags us and our kayak across the marsh. We are in Goose Lake Prairie State Natural Area, about 50 miles southwest of Chicago. We visit these wetlands two weeks per month during the field season, which runs from May to October. Building a prairie and watching for bees Aug 6, 2020 8:30 am1356 views It’s early evening as I follow the researchers to their work site on the Phillips Tract, just east of Urbana. When we get there, I immediately notice two things: We are standing in a vast grid of prairie plots with neatly mowed paths between them, and there are tents – dozens of dollhouse-sized tents. Two years ago, entomology professor Alexandra Harmon-Threatt built this outdoor laboratory by planting more than 80 prairie species here, most of them flowering plants. Her mission is to attract wild ground-nesting bees. She is here to see which bees are showing up and how they’re doing. But that’s not all she’s after. Chasing bumble bees on a patch of prairie Jul 20, 2020 1:30 pm5552 views It’s hot and the key to the gate doesn’t work. Heavy clouds hover to the north and east, and a distant rumble warns of potential rain.“Looks like you’re going to get the full prairie experience,” Tommy McElrath says. To our right is Trelease Woods, a remnant 65-acre patch of old-growth forest owned by the University of Illinois. To the left, a slice of restored prairie. We’re here to get a glimpse of what’s left of the 18 species of bumble bees recorded here in decades past. Grace and healing: Parkinson's dance class opens pathways to body and mind Jun 12, 2020 8:15 am1995 views Laughter ripples across the dance floor. Bodies bend in an arc. For some, that arc is much less pronounced, but that’s not important. Any expansion of movement is a celebration for these dancers – they have Parkinson’s disease. This is a session of Dance for People with Parkinson’s, a tradition for more than 10 years at the University of Illinois at Urbana-Champaign. Rediscovering a path to the Milky Way May 6, 2020 8:15 am2599 views We’re standing on a roadside at the edge of a muddy expanse. I’m wearing rubber boots, but Tim Pauketat is going to get his feet wet. He left his waterproof boots in Indiana, but this won’t stop him from tromping out into the soggy, overgrown remains of the ancient city of Cahokia. Dehydrating plant proteins at the speed of sound Apr 17, 2020 1:15 pm1318 views Food scientists at the University of Illinois devised an energy-efficient, cost-effective method for drying plant proteins using high-frequency ultrasound. Rohit Bhargava: My path to Illinois Apr 9, 2020 8:15 am2355 views I grew up in Jaipur, India, a city that is well-known for its architecture. My father is an architect, and I grew up helping him, looking at plans and making blueprints. I was always interested in building things. Will Schneider: My path to Illinois Apr 6, 2020 9:00 am888 views Social work professor Will Schneider examines trends in child maltreatment and suggests that interventions for child neglect overlook the most likely cause. Patrick Earl Hammie: My path to Illinois Apr 2, 2020 8:45 am1421 views Patrick Earl Hammie is a professor of painting and sculpture whose work explores the body in visual culture, black experiences, cultural identity and family.
