Editor's note: The S&P 500 spiked 9.5 percent Wednesday after President Trump announced a 90-day pause on proposed tariffs.

U.S. financial markets continued their week-long roller-coaster ride Wednesday, rattling the nerves of the roughly two-thirds of Americans who hold stock of some kind.

“Seeing trillions of dollars of wealth disappear from people’s retirement accounts in two days is pretty shocking,” said Shaun Davies, referring to last week’s market sell-off after President Donald Trump announced sweeping global tariffs. “Any of us who have logged into our 401Ks recently have had to get the Tums out.”

��ɫ��Ƶ Today caught up with Davies, associate professor of finance at the Leeds School of Business, to get his take on the recent stock market plunge, how worried we should be, and what’s to come.

Shaun Davies

Has anything like this ever happened before?

This is unusual, but not unprecedented. Not to bring up the Great Depression, but, we saw corrections like this in 1929. We saw them when France was taken over by Germany during World War II. We saw them in October of 1987, when, on “Black Monday,” the Dow dropped 22% in a single trading session, and again in the early 2000s with September 11 and the dot-com bubble bursting. The one that's most salient to most of us is the 2008 great financial crisis after the fall of Lehman Brothers, and there was a short little blip in March of 2020, during COVID.

Some might be tempted to pull their money out. What would you tell them?

Last week definitely blind-sided markets. Everyone knew these tariff announcements were coming out. But they were far more extreme than expected. When you see markets down 10% over two days, you say, I don't want to be a part of this. But it's really hard for an individual to time markets and know when to stay in and get out. One of the best things you could do is talk to a professional. When markets are up, nobody thinks they need financial advice. But during times like this, when they talk you off the ledge from doing something you’ll regret, they’re really valuable.

But why stay in?

You have to separate yourself emotionally from the investment and remember that, in exchange for our willingness to take risk, we earn compensation during good times. For example, in 2023 and 2024 the S&P 500 was up over 20%. That is compensation for moments like right now. Back in March of 2009, the market was plummeting. Everyone wanted to get out. But if you did, you missed one of the best bull runs in stock market history. Your goal is to build wealth over that long runway to retirement, where your good years offset your bad years and you make something like a 10% or 15% average return per year over that horizon.

What if your kid is going to college soon?

The 529 (college savings plan) is unique in that it's a relatively short horizon from when you start contributing to when you withdraw. If you’re concerned that tuition is due in the fall and you feel like you have a sufficient amount, it may be prudent to pull that money out, put it into something like a money market fund, where you'll still get a little over 4%, and at least you know you have that nest egg for tuition. Again, talk with your financial advisor.

What if you have cash to invest right now? Should you just tuck it under your mattress?

No. You definitely do not want to put your money under the mattress. We are in a period of relatively high inflation, still about 3%, so if you are just holding on to cash you are going to lose purchasing power because goods are going to go up in price. If you want something safe and short-duration, consider a money market fund, short-term U.S. Treasury bills, or short-duration U.S. Treasury Inflation Protected Securities (TIPS).

How is this different than past corrections?

2008 was a very scary time, because lots of governments, companies and pensions were holding bonds backed by things like subprime mortgages, and we had no idea what they were worth. In 2020, with the global pandemic, it was a quick blip with a quick recovery.

The concern here with these tariffs is the impact of all the uncertainty on the real economy. I can't imagine being a CFO of a fortune 500 company debating whether to take production on shore. You might make some huge capital investment, build factories in the United States, and then the U.S. tariff policy totally changes with a single tweet. If I were a CFO right now, I'd just be sitting on my hands, and that's going to have real implications. I imagine we're going to see corporations providing guidance that the next few years may not be as profitable. We're going to have supply chain disruptions. It could disrupt the labor market. Who knows?

How long will this craziness last?

There's a great gauge of volatility called the VIX index, which tracks the potential for volatility in the market over the next 30 days. The math is a bit complex, but one truism is that a high VIX corresponds with high anticipated volatility in returns. A normal VIX is between 15 and 20. This past week, we've seen the VIX around 50, which is huge. Buckle up. It’s going to be a roller coaster.

People of color breathe Denver’s smelliest air

In Denver, people of color and those with lower household incomes are more likely to live in neighborhoods near facilities that emit bad smells, a new ��ɫ��Ƶ-led study reported.

For many Denver residents, the city’s crisp mountain air is a perk of living near the Rocky Mountains. But every so often, a gust of wind can carry less welcome scents, like the pungent odor of pet food factories or the skunky smell of marijuana grow houses.

In a paper published Feb. 22 in the Journal of Exposure Science & Environmental Epidemiology, scientists revealed inequality in exposure to Denver’s odor. The research found that while racial minorities and socioeconomically marginalized communities are more likely to be exposed to bad smells, residents in gentrifying neighborhoods file more odor complaints.

If you experience strong environmental odors:

Submit a complaint to the City and County of Denver by phone at 720-913-1311, or email at 311@denvergov.org.

“Our study suggests that there's potentially an underreporting of odor in certain neighborhoods,” said first author Priyanka deSouza, a researcher with ��ɫ��Ƶ’s Institute for Behavioral Science and assistant professor at the University of Colorado Denver. “Some residents in these communities that are disproportionally affected by odor may not feel that their voices are being heard.”

Before 2016, Denver, like many cities across the U.S., used an inefficient and archaic way to address odor issues, according to Shelly Miller, the paper’s senior author and professor in the Department of Mechanical Engineering at ��ɫ��Ƶ.

Traditionally, when the city received complaints about an odor issue, an odor inspector would go to the site and sniff through an odor measuring device, but these inspections often found nothing. Because odor is very transient, by the time the inspector arrived, the smell might be long gone.

“Odor is a complex issue. It’s very hard to measure, and it’s subjective. You probably smell things differently than I do, but that doesn’t mean what you’re smelling is any less valid than what I’m smelling,” Miller said.

Miller’s previous studies in odor and air quality, as well as concerns from local communities, prompted the Denver Department of Public Health and Environment to update its air pollution control ordinance in 2016. A new rule requires odor emitting facilities, including pet food factories and marijuana growers, to submit odor control plans if they receive five or more complaints within a 30-day period.

“This updated rule is one of the most innovative odor ordinances of all major cities in the U.S. It’s willing to take action based on community complaints,” deSouza said.

The team mapped out all 265 facilities in Denver that had to submit an odor control plan as of 2023. More than 96% of these facilities were marijuana growers, processors and manufacturers. The rest included pet food manufacturing, oil refining and construction.

They found that malodorous facilities are more often located in historically redlined neighborhoods. After the Great Depression, the U.S. government implemented a racist and discriminatory policy that designated neighborhoods with racial and ethnic minority residents as high-risk, or “red” for mortgage lenders.

In Denver, these neighborhoods are located along the city’s two major interstate highways, I-70 and I-25, and still host a higher percentage of people of color. A prior ��ɫ��Ƶ study revealed that residents in these historically redlined areas are exposed to higher levels of air pollution.

When the team compared the odor facility map to an odor complaint map, they found that neighborhoods more susceptible to odor did not file more complaints than other neighborhoods. Instead, more complaints per population came from older neighborhoods that are transitioning into more modern, wealthier neighborhoods, like River North in Denver’s city center.

It is unclear why gentrification has led to more odor complaints, but it could be that the more privileged feel more empowered to file complaints, the authors said. New residents could also be more sensitive to the city’s smells compared to long-term residents.

“Given that odor complaints are the primary driver for Denver to take action on odor control, I hope our findings could encourage the city to continue working on rebuilding trust with these communities and empower them to use the tool,” deSouza said.

'You don't throw them in plastic bags or boxes.' Archaeologists, Indigenous scholars call on museums to better care for animal remains

'You don't throw them in plastic bags or boxes.' Archaeologists, Indigenous scholars call on museums to better care for animal remains Daniel William… Mon, 03/10/2025 - 10:01

Two years ago, Chance Ward began opening boxes of horse remains that had been shipped to the CU Museum of Natural History from other institutions around the country. What he saw made his heart sink.

At the time, Ward was a master’s student in Museum and Field Studies at ��ɫ��Ƶ. The researcher, who had grown up riding horses, was taking part in a large-scale study exploring the history of these iconic animals in the American West. But when he looked inside the packages, he sometimes found bones in disarray—horse remains were in bags and boxes with little care or cushioning and had banged together in transit, occasionally causing damage.

Ward is a member of the Cheyenne River Sioux Tribe in South Dakota and a member of the Mnicoujou and Hunkpapa bands of the Lakota Nation. Lakota traditions, like those of many other Native American groups in the West, place animals at the center of their spirituality and view them as relatives.

“You care for horses. You not only feed and water them, but you connect with them on a personal, spiritual level,” Ward said. “Even when they pass on, you still respect and honor them as non-human relatives. You don't throw them in plastic bags or boxes.”

Today, he’s leading a team of archaeologists and Indigenous scholars urging museums around the country to take a more respectful approach to caring for animal remains. It’s an example of what the researchers call “cultural humility,” an approach to engaging with different cultures that emphasizes self reflection, lifelong learning and recognizing power imbalances. The team says that museums must partner with Native American groups to rethink how they catalogue, store and display remains.

The group laid out its approach in a paper published this month in the journal Advances in Archaeological Practice.

“Now that Native people are getting into the museum field more, there’s been a greater understanding of things like representation and having control over our own cultures and issues that affect our cultures,” Ward said. “The old way of doing archaeological methods is outdated and in need of fresh perspectives.”

William Taylor, curator of archaeology at the CU museum and the study’s senior author, agreed. In 1990, U.S. Congress passed the Native American Graves Protection and Repatriation Act (NAGPRA). It requires institutions that receive federal funding to return human remains, sacred objects and more to Indigenous people.

But NAGPRA, which often doesn’t apply to animal remains, is not the only principle that should guide how museums act, said Taylor, author of the 2024 book Hoof Beats: How Horses Shaped Human History.

“We need to reframe the way we think about museums. Are they places where we treat archaeological objects as inanimate things?” he said. “Or are they places of living stewardship that come with responsibilities, some of which include connecting and listening?”

Life on horseback

Ward, who now serves as the NAGPRA Coordinator for the State of Colorado and Office of the State Archaeologist, grew up on the Cheyenne River Reservation where horses were an essential part of his life. His father’s family owned a ranch, and every spring, Ward helped to round up cattle on horseback. He remembers when his dad first put him on a horse at age 8.

“There was no riding lesson. It was just ‘get on, and let’s go,’” Ward said. “I remember telling myself, ‘I’m not going to fall off no matter what’ because I didn’t want to disappoint anyone.”

Historically, the field of archaeology hasn’t always treated animals with respect. During many early digs, researchers overlooked the animal bones they found during their work. They often removed those objects from their cultural context and even threw them away.

Ward wants to change that. He noted that there’s no one-size-fits-all approach for how to treat the remains of horses, bison and more. There are currently more than 570 federally recognized Tribes in the U.S. and more recognized by the states, all of which hold their own distinct views on the living world.

But museums can begin by thoroughly documenting all the animal remains they have in their collections. Many institutions, Ward said, don’t even know what kinds of bones they have hiding in boxes and cabinets in rooms away from the public eye.

Study co-author Jimmy Arterberry, a tribal historian for the Comanche Nation in Oklahoma, sees the new paper as an urgent call to action. He acknowledges that most museums today are short on funding and staff. But he says institutions can still do a lot right now to change how they handle animal remains.

“Why are you keeping them if you’re not going to care for them?” Arterberry said.

Bison herd

Arterberry and Ward agree that the most important thing museums can do today is listen to Native American groups. NAGPRA requires museums to obtain consent from Native American nations around how these institutions store, house and treat many archaeological collections.

The CU museum is committed to strengthening relationships and honoring knowledge. Taylor and his colleagues began with one of the museum’s most extensive collections: In the 20th century, archaeologists at the museum unearthed thousands of bison bones from an arroyo near the tiny town of Kit Carson, Colorado. Ancient peoples had hunted and butchered the animals following the end of the last Ice Age roughly 11,000 years ago. Archaeologists originally stored nearly 200 bison skulls in plaster or burlap casts. But decades later, many of those casts were fragmenting, threatening the remains inside.

Over several months, the team transferred the skulls to stable and open casts and arranged them safely on shelves in a new storage space. In February 2024, a delegation of Lakota elders traveled to the ��ɫ��Ƶ campus to meet with researchers and to see the bison collection. Chief Harold Left Heron spoke and sang a blessing in the Lakota language as he stood next to the remains.

“One of their suggestions was to keep these animals together as a herd in the museum, as they might have been in life,” Taylor said.

Going forward, he said, the museum will continue seeking out opportunities to build community perspectives into the care of ancient animal remains.

Ward said that anyone can learn a lot by forming interpersonal relationships with animals like his own favorites, horses.

“Just being there with them, standing next to them, feeling them physically and spiritually is very powerful,” he said. “It takes both sides, the horse and human, to connect with each other and be comfortable—but not so comfortable that we dominate them.”

Other co-authors of the new study include Christina Cain, former collections manager at the CU Museum of Natural History; Dr. Joseph Aguilar at the Tribal Historic Preservation Office for Pueblo de San Ildefonso in New Mexico; Natalie Patton, a graduate of the CU Museum of Natural History; and Dr. Emily Lena Jones at the University of New Mexico.

1 in 15 US adults have been on the scene of a mass shooting

About 7% of U.S. adults have been present on the scene of a mass shooting in their lifetime, and more than 2% have been injured during one, according to new ��ɫ��Ƶ research.

The study, published March 7 in the journal JAMA Network Open, also found that younger generations were significantly more likely to have been exposed than their parents or grandparents were.

Generation Z—adults born after 1996—were at greatest risk.

“This study confirms that mass shootings are not isolated tragedies but rather a reality that reaches a substantial portion of the population, with profound physical and psychological consequences,” said senior author David Pyrooz, a professor of sociology and criminologist in the Institute for Behavioral Science at ��ɫ��Ƶ. “They also highlight the need for interventions and support for the most affected groups.”

A ripple effect

For the study, Pyrooz and his colleagues surveyed a nationally representative sample of 10,000 adults in January 2024. (The researchers chose January because the month tends to see a lull in mass shootings.) They asked a series of questions, including: “Have you personally ever been physically present on the scene of a mass shooting in your lifetime?”

The group defined “mass shooting” as a gun-related crime where four or more people were shot in a public space. The researchers defined “physically present” as “in the immediate vicinity of where the shooting occurred at the time it occurred, such that bullets were fired in your direction, you could see the shooter, or you could hear the gunfire.”

Just under 7% of respondents answered yes. Just over 2% of respondents said they had been injured, which not only includes having been shot, but also hit by shrapnel, trampled by people fleeing the scene or other injuries.

“We are talking about one out of every 15 people in the United States,” said Pyrooz. “These are really high numbers for this seemingly unique and small subset of gun violence,” said Pyrooz.

While these numbers might seem high, Pyrooz said he was not surprised by the survey results. A single mass shooting can impact far more people than many realize.

For instance, during the 2017 shooting at the Route 91 Harvest Music festival in Las Vegas, the shooter killed 60 people and wounded 413 others. But another 454 people were injured during the ensuing panic as people fled to safety. In all, there were about 22,000 people at the concert—plus onlookers from surrounding hotels on the Las Vegas strip.

“That translates to about one out of every 11,000 Americans who were on the scene of that shooting alone,” said Pyrooz. “Continue that to other events that have occurred around the country and the numbers, unfortunately, add up.”

The ‘mass shooting generation’

Black people and males were more likely to have witnessed a mass shooting.

More than half of the respondents who had been present during a mass shooting said it happened in the last decade—a finding that reaffirms the notion that younger generations are experiencing a cultural phenomenon their parents didn’t have to deal with.

“Our findings lend credence to the idea of a ‘mass shooting generation,’” said Pyrooz. “People who grew up in the aftermath of Columbine have these unique experiences that are really distinguishable from the older population.”

Three-quarters of the respondents experienced mass shootings in their local communities—in places like bars or restaurants, schools, shopping outlets and synagogues.

More than one-third of mass shooting happened in neighborhoods.

"These are primarily shootings that occur between gangs or crews, and related actions, which occur in parking lots, yards, porches or other residential locations," said Pyrooz. "It's the type of mass shooting that completely escapes media attention."

The income and education level of respondents had no measurable impact on their chances of being present, or injured, at a mass shooting.

The aftermath

The study did not quantify how mass shootings impact mental health, but Pyrooz and his colleagues are publishing a forthcoming paper that will.

It found that about three-quarters of those who were present at the scene of a mass shooting but uninjured still experienced psychological distress, including fear, anxiety and depression. (For comparison, about 20% of people in the general population report these symptoms.)

Pyrooz hopes the ongoing research will help fill a research gap around the public health impacts of the relatively new, and understudied, phenomenon of mass shootings. He also hopes it will underscore the need to support programs aimed at reducing gun violence, and bolster supporting those suffering lingering effects from exposure.

He can still remember the sound of the sirens from the March 22, 2021, mass shooting at a King Soopers just miles from his office in Boulder.

He wasn’t personally exposed but knows what a toll it took on his own community.

“It’s not a question of if one will occur in your community anymore but when,” he said. “We need to have stronger systems in place to care for people in the aftermath of this tragic violence.”

��ɫ��Ƶ criminologist David Pyrooz calls for more mental health support for people who have been exposed to gun violence.
