What should we make of the new CDC guidance for isolation and quarantine?
UWMadScience
by Kelly April Tyrrell
2y ago
On December 27, 2021, the Centers for Disease Control and Prevention changed its guidance for some people who test positive for COVID-19. Instead of 10 days of isolation from either the time you test positive or the day your symptoms begin, the agency says COVID-positive people can now end isolation after five days if you don’t have symptoms, or if your initial symptoms have improved. The change, says CDC, comes amidst evidence that people are typically most infectious — and therefore, most likely to transmit the virus to other people — in the days immediately preceding and closely following t ..read more

Air quality: from cities to space
UWMadScience
by Emma Roberts
2y ago
From high-profile wildfires in the American West over the last several years, to visibly cleaner air during pandemic lock-downs, air quality is returning to the forefront of environmental concern. The air we breathe has direct impacts on human health and quality of life. Especially for people with respiratory concerns, sufficient air quality is essential.  The issue is: solutions cannot be implemented without knowing where the problem areas are or what to clean up. Tracey Holloway “We just don’t have enough ground-level information to know what people are breathing,” says Tracey Hollowa ..read more

“Immunized” or “Vaccinated”: What’s the difference?
UWMadScience
by Eric Hamilton
2y ago
This post is by student science writer Rachael Lee. When Green Bay Packers quarterback Aaron Rodgers announced he’d tested positive for COVID-19, the news shocked football fans everywhere, in part because Rodgers had told the public he was “immunized.” Most people took that to mean he’d been “vaccinated.” However, Rodgers has since shared that he received treatments other than the federally authorized or approved COVID-19 vaccines. Throughout the course of the pandemic, the public has been bombarded with sometimes conflicting information about the science and medicine behind COVID-19. The conf ..read more

This is the first post by new student science writer Rachael Lee. Welcome, Rachael! The Veterinary Sports Medicine and Rehabilitation (VSMR) Club provides new opportunities for students to gain insight into this growing field. All over the world, athletes spend countless hours training to perfect their technique. To mend the physical toll it takes, there are teams of physical therapists, nutritionists, and researchers taking care of these athletes.  The recently founded Veterinary Sports Medicine and Rehabilitation (VSMR) Club at the University of Wisconsin–Madison’s School of Veterinary ..read more

Mid-October’s high temperatures come with a consequence for lilacs and other plants

This is the first post written by student science writer Emma Roberts. UW Arboretum lilacs in bloom on Oct. 20, about 6 months after their usual flowering period. (Photo by Emma Roberts) While Madison’s residents soaked up the above-average October temperatures, the heat has given some plants mixed signals. Instead of entering dormancy for the winter, some species have begun to rebloom. The lilac plants that bring many to the University of Wisconsin–Madison’s Arboretum around Mother’s Day have put on an unscheduled show this month. For the past three weeks, people have taken notice of t ..read more

Darwin Day switches virtual for the first time over pandemic concerns

If you’ve ever been in the Wisconsin Institutes for Discovery the week of February 10th, you’ve probably heard of or witnessed Darwin Day, put on by the J.F. Crow Institute for the Study of Evolution. Every year, researchers across the University of Wisconsin–Madison campus come together on the father of evolution’s birthday to share their evolution-focused work and conduct outreach with K-12 students about one of biology’s most integral discoveries. But this year, things look a little different. Last year, Darwin Day just barely missed the advent of the COVID-19 pandemic in Wisconsin. This Fe ..read more

Planetary rendezvous: The grand conjunction of 2020

This post to us comes from Dr. Jim Lattis, director of UW Space Place. On December 21, Jupiter and Saturn, now in our evening sky as they have been for months, will appear very close together — so close that, depending on your visual acuity, you might need binoculars or a telescope to separate them! A conjunction, an apparent coming together, as close as this between the two giant planets is relatively rare. It has been about 400 years since the last conjunction this close! Although the closest apparent approach of the two planets to each other comes during our daylight hours on the 21st, they ..read more

Rare mirage dominates Madison skyline

This post was written by student science writer Mary Magnuson Thanks to atmospheric distortion, the distant Blue Mound appears to loom as a mesa west of the Wisconsin State Capitol. (Photo by Tim Wagner) The morning of December 2, the Madison skyline looked considerably different — as if the city had been transported out west, where mountains and mesas tower. In an image captured by Cooperative Institute for Meteorological Satellite Studies atmospheric scientist Tim Wagner, an atmospheric phenomenon made a dark mound appear, which looked similar to a plateau rising above the city. But, as Wa ..read more

As monarchs arrive in their summer ranges, citizen scientists aid in monarch conservation
UWMadScience

Student science writer Mary Magnuson wrote this post. When spring turns to summer, there are three things to count on: longer days, warmer weather and the return of monarch butterflies. Every year, thousands of monarchs make their way down south to Mexico in the early fall, where they wait out the winter in cool forests. In the spring, they come back up north, stopping to lay eggs along the way. They may not make it all the way back up north, but their offspring will continue their migration. This year, the first monarch in Wisconsin was spotted May 7 in Middleton. Monarch butterfly on rough ..read more

The Legacy of the 5307th Merrill’s Marauders: Wisconsin MIAs in Burma
UWMadScience
by Chris Barncard

This post was written by Vaneesa Cook, historical research fellow for UW–Madison’s Missing in Action Recovery and Identification Project. In the winter of 1944, while many Americans were tracing the progress of Allied island hopping throughout the Pacific, a special unit of U.S. soldiers set out on foot across hundreds of miles of mountains and thick jungle on a mission that commanders estimated would result in at least eighty-five percent casualties. They were right. By the end of the summer, the nearly 3,000 infantrymen of the “Merrill’s Marauders,” the Army’s 5307th Composite Unit (Provisio ..read more
