抖阴短视频

In January 2020, 抖阴短视频 Boulder researchers were already facing a busy year.听

Leslie Leinwand, a professor of molecular, cellular and developmental biology, was developing new treatments for inherited heart diseases. Integrative Physiology Professor Matt McQueen had just kicked off a nationwide concussion study. Shelly Miller, a professor of environmental engineering, was studying harmful airborne emissions produced during cooking. Biochemist Roy Parker was investigating the role messenger RNA plays in disease.

They worked at opposite ends of campus, in disparate fields toward distant goals. Some had never met. Some probably never would have.

Then, a mysterious virus started making headlines, and after its first confirmed case on campus, 抖阴短视频 Boulder, unfathomably, ceased in-person operations March 16.听

One by one, a team of often-siloed scientists began to pivot, back-burnering their own research and personal lives to face a daunting challenge: to bring 31,000 students back to campus safely in the midst of a deadly virus easily spread by young people who don鈥檛 know they have it.

鈥淲e were just this rag tag team that started meeting over Zoom,鈥� said Leinwand, who in early spring convened a dozen volunteers for 90 minutes after work to begin hashing out a plan.听

They鈥檇 meet for nearly a year, seven days a week, sometimes multiple times a day, with pets and kids wandering into their frames as their meals got cold.听

鈥淭here was no primer and no precedent. We were just learning as we went,鈥� recalled Leinwand, who pulled in volunteers from Student Affairs, Medical Services and Facilities Management to help deploy the science-based solutions taking root. 鈥淚t was intense.鈥�

Today, the machine they quietly built together is humming along smoothly. On the second floor of the BioFrontiers Institute, a young team of 鈥淐OVID Warriors,鈥� as they call themselves, processes up to 2,500 saliva samples daily, from free campus screening sites using a new test invented in Parker鈥檚 lab.听

Results are recorded one-by-one, late at night, by a sometimes bleary-eyed post-doctoral researcher, Kristen Bjorkman, who volunteered to help last spring and never stopped. Then, they鈥檙e delivered via a smartphone app developed by campus computer scientists. When a student tests positive, via a follow-up diagnostic test at Wardenburg, one of 80 student contact tracers convened by McQueen last spring, kicks into action.

Meanwhile, an expansive monitoring system, conceived by an environmental engineer named Cresten Mansfeldt鈥攚ho鈥檇 arrived on campus just four months before COVID hit鈥攖racks wastewater from residence halls for early signs of the virus.

Students are again attending classes and playing music, with masks, instrument covers and improved ventilation informed by Miller鈥檚 research on airborne transmission.

While many universities continue to operate primarily online, 抖阴短视频 Boulder is inching its way back to something resembling a normal campus.听

Provost Russ Moore credits science.

鈥淣o one ever dreamed that the impact of this pandemic would be as large and lasting as it is, and we and other universities were knocked on our heels trying to respond to the unknown,鈥� Moore said. 鈥淲ithout anyone asking them, this small group of people dropped their lives and said, 鈥楲et鈥檚 do what we can to keep this campus going.鈥� They didn鈥檛 ask for credit or care who knew about it. They just dove in and got it done.鈥�

Sleepless nights and lasting legacies

Even before the pandemic, Leinwand, chief scientific officer of the BioFrontiers Institute, didn鈥檛 sleep much.

鈥淗onestly, I think it鈥檚 a waste of time,鈥� she said of the five hours she gets nightly. 鈥淚f I could do away with it entirely I would.鈥�

She keeps a small notepad on her bedside, waking often to scribble ideas or work through problems. In spring of 2020, after Chancellor Phil DeStefano suggested she spearhead development of a COVID-response plan, she churned through those notebooks.

At the time, existing nasopharyngeal tests鈥攏ot-so-fondly referred to as 鈥渂rain probes鈥濃�攚ere in short supply and taking as long as nine days to return results.

Leinwand and Parker began developing a plan for monitoring on campus.

鈥淲e looked at what was happening around the country and realized we needed to develop the capacity to do some things on our own,鈥� said Parker, who has spent his career studying RNA (ribonucleic acid), the molecular messenger that carries genetic information for many viruses, including SARS-CoV-2.

Two research associates who had worked in Parker鈥檚 lab for decades, Carolyn Decker and Denise Muhlrad, put their heads together to help develop a fast, sensitive test more amenable to college students鈥攂ased on saliva instead of nasal samples.

鈥淚 felt like most things were out of control in the world around me, but this was some small way that I could have control and be helpful,鈥� said Decker.

As she refined the test, Muhlrad designed novel primers and scoured the internet for reagents and precious PCR (polymerase chain reaction) machines, which can detect the genetic material of SARS-CoV2 in less than a thimble full of spit.

She worked long days on campus and late into the night at home for months to get the lab set up in time for students鈥� return.

On July 28, volunteers erected a white tent at the Champions Center on campus and began collecting their first saliva samples from students.

Three months later, Muhlrad died suddenly from a previously undiagnosed heart problem, a devastating loss for Parker, Decker and other colleagues who continued their work while mourning a dear friend.

Her last scientific endeavor has left a potent legacy for her community. 听

鈥淪he was not one to toot her own horn and she could be a bit stoic, but I know she was proud to be a part of this,鈥� said her husband Paul Muhlrad, science communications manager for the Department of Molecular, Cellular and Developmental Biology.

Beyond testing

In the weeks before school started, Parker found himself in an odd position for the director of a biomedical institute: Clad in shorts and sandals, he went from porch to porch on University Hill, urging students to come get a COVID-19 test.

Leinwand remembered spending one night scouring the internet for rental cars, to move saliva samples from tents to the lab.

McQueen, meanwhile, was working a different puzzle.

鈥淲e also needed isolation spaces and environmental controls and ventilation and signage and hand sanitizer and鈥�,鈥� he said, recalling how he toured every classroom, hallway and community space with Facilities Management, Student Affairs and Medical Services staff. 鈥淵ou didn鈥檛 have time to breathe and think and wait for a paper to be published on it, you just had to move and accept the fact that you might get it wrong sometimes.鈥�

Come fall, as students returned to campus, cases surged, critics pounced and the team couldn鈥檛 help but be disappointed.

鈥淲e鈥檇 get results back at 1 a.m. and we鈥檇 all be watching our email. Sometimes we were on the phone in the middle of the night,鈥� said Leinwand.

McQueen said that, of all the things they did right, they failed to consider the impact that off-campus social gatherings could have on the pandemic, an issue that continues to plague the community鈥檚 COVID-19 response. All the testing in the world won鈥檛 make up for bad behavior, said Parker.

Despite the fall surge faced by universities nationwide, 抖阴短视频 was able to flatten the curve.

While more than 2,100 cases of COVID-19 have been confirmed to date via campus testing, not a single one has been shown to have been transmitted in the classroom.听

Transmission within residence halls has also proven remarkably low.

鈥淥ur system, while taxed and stretched, worked,鈥� said McQueen.

How COVID-19 changed science

The team meets less often now, and when they do, they feel the freedom to cut loose a little. On holidays, they delivered their favorite holiday dishes to one another鈥檚 doorsteps, enjoying them within the confines of the familiar Hollywood Square on Zoom. When someone has a birthday, a cake or flowers often appear at their house.

鈥淲e built this community of trust and respect and we came to really like each other,鈥� said Leinwand.

Science also changed. Instead of hunkering down and moving slowly, researchers discovered how quickly they could make things happen in collaboration across disciplines.

鈥淐OVID changed us, forcing us to cross boundaries that prior to the pandemic seemed impenetrable and make things happen at lightning speed because we genuinely care about this community,鈥� said Moore. 鈥淢y greatest hope is that this spirit of collaboration lasts.鈥�
