UM research Dr. Danhao Wan reportedly committed suicide after being questioned by federal authorities, revealing a broader pattern of political discrimination.
On April 17, CODEPINK and the local University of Michigan community gathered to hold a vigil in honor of UM researcher Dr. Danhao Wan on the one-month anniversary of his death. According to reports, Dr. Wang died after jumping from an upper floor of the G.G. Brown Building on North Campus, shortly after being targeted and questioned by federal authorities.
Over 30 members of the local community attended the vigil, bringing candles and flowers. They joined in a traditional Chinese bowing ceremony. During the vigil, CODEPINK and US Peace Council member Bob McMurray spoke to the crowd: “Tonight, I want us to remember there is a Mom and Dad mourning the loss of their son; there are people here in the university research community feeling his absence every day; and we, as the human family, have lost a brother.”
For weeks, Dr. Wang’s death went uncovered by the media. By the time it hit the news, the Chinese Consulate in Chicago had already confirmed the incident as a suicide and demanded an investigation of the “unwarranted interrogations and harassment of Chinese students and scholars.”
This is not the first time a Chinese scholar has been targeted at the University of Michigan; it is part of a broader pattern of political discrimination. In the last year, five Chinese scholars have been accused of various crimes, detained for months on end, and ultimately deported after the quiet dismissal of their cases due to a lack of evidence.
When individuals like Dr. Wang are targeted, it is not only their livelihoods that are threatened, but the very purpose and meaning they have built their lives around.
This discrimination is not new. In 2018, the Trump administration launched the China Initiative, a deeply flawed and racially biased program that targeted Chinese and Chinese Americans for “suspected espionage.” More often than not, federal authorities targeted individuals with no evidence of wrongdoing—simply for their identity. As a result, a new climate of suspicion and fear took root across academia. Though few convictions were made, many Chinese scholars suffered permanent professional and personal harm. They began to self-censor, withdraw from collaborations, or leave the United States entirely. For them, the US was no longer safe.
Although the China Initiative was formally ended under the Biden administration due to widespread criticism of its racial bias, its underlying logic has not disappeared. Instead, it has evolved into a broader atmosphere of suspicion directed at Chinese scholars, particularly in fields tied to advanced technology and science. At the University of Michigan, this pattern is especially visible.
Take the case of Dr. Chengxuan Han, a Chinese PhD student who was arrested for mailing roundworms commonly used in biological research. In most academic contexts, such an error would result in a minor administrative penalty. Instead, she was jailed for months and subjected to a full criminal prosecution. This outcome was wildly disproportionate to the alleged offense and one that effectively ended her academic trajectory.
Another scholar, Dr. Yunqing Jian, was accused of "agricultural terrorism” for breaking protocol and shipping materials to the US without the proper paperwork. Renowned biologists refuted this claim, saying it was impossible to use Fusarium graminearum, the fungus Dr. Jian studied, as a bioterrorist weapon. In the world of research deadlines and red tape, scholars say it's typical to try to streamline research by acquiring your own materials, even if that means skipping some paperwork. Dr. Jian has spent years researching how to mitigate the harm caused to crops by Fusarium graminearum, which is native to North America. While she did break protocol, it is absurd to accuse her of weaponizing the fungus, especially without any evidence.
Similarly, the cases of UM scholars Xu Bai, Fengfan Zhang, and Zhiyong Zhang demonstrate how ordinary research practices were reframed as criminal acts merely because of the identity of the scholars. Even though charges against them were dropped and the cases dismissed, the damage had already been done.
The three scholars had spent months in jail awaiting their trial. In a letter, Zhiyong Zhang spoke of his confusion over the situation:
I like the research atmosphere in the University. I like the people here. They are kind and polite. I am living a happy life here. However, unfortunately and apparently, some people don't like us. They want to connect us with politics. But what is politics? I didn't know what politics is when I was 13 years old, at which age I decided to study biology. Now I am also confused about what politics is. It's so abstract. We didn't hurt anyone, and we don't want to hurt anyone, either. We just want to do research and find something that can benefit humanity. That makes me feel my life is meaningful, although I can not make much money.
Zhang decided to study biology because his grandfather and father were both diagnosed with Parkinson’s disease in their mid-30s: “I thought I could change to study neuroscience to cure the disease of my family and all the people who are suffering the pain from the disease… So this is what I am doing here.” At 32, he worries he will soon suffer the same fate.
Originally, the three scholars were informed by the University of Michigan that they had 30 days to pack and leave. Since they’d spent all their free time in the laboratory, they decided to use their last few weeks to visit the Grand Canyon. While there, the UM administration backtracked on their words, informing the scholars they had to leave immediately. At the airport, while attempting to return home, they were intercepted by Immigration and Customs Enforcement and arrested.
This was no coincidence. The UM administration not only provided the wrong information, but they also had terminated their SEVIS status, which gave them permission to live and study in the US, making them vulnerable to federal authorities at passport control.
The repeated pattern points to a system in which Chinese researchers are treated as potential threats merely on the basis of their identity—which is all a part of the larger campaign to paint China as an enemy of the United States.
Dr. Danhao Wang’s life and work stand in stark contrast to this narrative. An assistant research scientist in the University of Michigan’s College of Engineering, Dr. Wang dedicated his career to advancing semiconductor technology. His research focused on gallium nitride, a material critical to modern electronics and essential for improving the speed, efficiency, and energy consumption of devices ranging from smartphones to renewable technology systems.
He made significant contributions to understanding how these materials behave at the atomic level, correcting long-standing assumptions and helping to unlock new possibilities for high-performance electronics. His work also explored how next-generation semiconductors could remain stable under extreme electrical conditions, paving the way for more efficient energy systems and emerging technologies.
We must put increased pressure on the University of Michigan and other universities to do more to protect their international students.
The repercussions of this research are vast. Semiconductors with such high performance potential could potentially make the data center industry obsolete by enabling a smaller device to do what normally takes an entire facility. For the US, gallium nitride semiconductors are the key to significantly improving its high-power weapons systems, and China’s current dominance over the material is considered a looming threat. This is all part of the US preparation for war against China, and the ongoing arms race around strategic resources and technology.
It’s reported that Dr. Wang was planning to return to China in May and already had a job set up. This raises even more questions over the circumstances of his death, and many Michigan locals have begun calling for an independent investigation.
Like most scientists, Dr. Wang’s research stemmed from deep intellectual commitment and passion. Years of specialized training, long hours in the lab, and a singular focus on discovery defined his life’s work. When individuals like Dr. Wang are targeted, it is not only their livelihoods that are threatened, but the very purpose and meaning they have built their lives around.
His death is a profound tragedy. And while the full circumstances remain unclear, it occurred within an environment where Chinese scholars have repeatedly been subjected to intense surveillance and unfair targeting.
The broader political climate cannot be ignored. Increasingly, US policy and rhetoric have framed China as a primary geopolitical adversary, particularly in areas like technology and national security. This framing has filtered down into academic spaces, where international collaboration between the US and China is now essentially criminalized.
The Chinese Consulate in Chicago has criticized the US for “overstretching the concept of national security” and has called for a full investigation and accountability. These demands should not be dismissed.
There must be transparency around the circumstances leading to Dr. Wang’s death. There must also be concrete safeguards to prevent discriminatory investigations targeting international scholars. This includes stronger legal protections, clearer institutional accountability, and accessible mental health support for those under investigation.
Universities, in particular, have a responsibility to protect their students and researchers. The University of Michigan is clearly doing the opposite. They are not protecting their students; they are instead actively targeting them by aiding these discriminatory investigations, putting all international students at risk.
We must put increased pressure on the University of Michigan and other universities to do more to protect their international students, to preserve the integrity of academic research, to protect international collaboration, and to ensure that scientific progress is not undermined by federal discrimination. If institutions fail to act, the cost will not only be measured in lost careers but in lost knowledge, lost innovation, and lost lives.
The biggest threat isn’t scientific uncertainty, since there’s a considerable amount of scientific consensus that there is plastic in us. The biggest threat is weaponized uncertainty used to delay regulations.
“Microplastics are everywhere, and they’re harming us.”
“Actually, maybe not.”
“Hold on, that study might be flawed.”
“Bombshell… the whole field is in doubt.”
The headline isn’t “microplastics in people might be wrong,” but rather “quantifying microplastics in human samples is challenging, and the science is evolving in the right direction.”
If you’ve been hearing about microplastics recently, you may have been getting whiplash from the headlines. But you shouldn’t be.
Because this is what science looks like when it’s working: Researchers test new ideas and challenge each other’s methods. This helps refine what we know. What isn’t supposed to happen is a normal, healthy, scientific process getting manipulated into a dramatic storyline about a fictional scandal—a story that can leave the public confused.
For over two decades, we’ve studied plastic pollution in the ocean. Scientists started describing the accumulation zones of plastic in the subtropical gyres, the places where wind and water currents concentrate floating debris. The research pointed to a truth that was complicated but clear: Most of the pieces are tiny, fragmented plastic—microplastics—along with some larger marine debris, like fishing gear.
But the media put a spin on it, and gave the world a simpler picture: a floating island of trash, “twice the size of Texas.” Some even called this a “garbage patch” you could supposedly walk on. People cried, “Why can’t I see it on Google Maps?” Some wondered if the US should plant a flag, and a handful of naive entrepreneurs fabricated fantastic ocean cleanup contraptions.
It was dramatic. Word spread. But eventually, it backfired.
All those who went looking for an island, didn’t find one. Instead they concluded, “It’s more like smog than a landfill,” and some pointed out, “Maybe it was exaggerated and the world had been duped.”
The pattern—one that goes oversimplify, sensationalize, backlash, dismissal—can drain urgency from a real crisis. Misinformation gets the headline. This gets repeated, as we’ve seen before in other environmental debates, such as the hole in the ozone layer, or climate change. The same thing is unfolding now with microplastics and human health.
The recent article in The Guardian that sparked this debate focuses on a real issue. In our research studying microplastics in the environment and animal studies, measuring micro- and nanoplastics in human tissue is incredibly hard. It is particularly difficult when researchers are looking for very small particle sizes, where laboratory contamination from airborne sources becomes harder to rule out. This is especially the case in human tissue.
Microplastics are not like other contaminants, such as lead in water, where you can measure parts per billion, and lean on decades of standardized instruments and test methods. Plastics come in many polymers, sizes, and shapes. Nanoplastics behave differently than microplastics. And plastic is everywhere, meaning background contamination is always a risk. This is sometimes called the “pig pen effect”—it is a challenge to study a material that is so widespread.
The Guardian article is not a devastating blow. It’s a scientific debate around specific methods in a research field that is rapidly improving.
The headline isn’t “microplastics in people might be wrong,” but rather “quantifying microplastics in human samples is challenging, and the science is evolving in the right direction.”
That difference matters. If the public hears “doubt cast,” then it translates it as “maybe plastic pollution isn’t really there or not that bad.” The question is, does it hold up across methods, across labs, across time?
So what has science taught us?
The biggest threat here isn’t scientific uncertainty, since there’s a considerable amount of scientific consensus that there is plastic in us. The biggest threat is weaponized uncertainty.
Environmental health has a predictable plot—when evidence starts piling up that a pollutant is harmful, a well-funded countermovement doesn’t always try to prove it’s safe. On the contrary, it tries to prove that the science is messy, uncertain, and “we need more data.”.
We’re not asking journalists to avoid urgency. Plastic pollution is urgent. Certain phrases, however, may signal that you’re being pulled into a pattern of mythmaking.
The industry has a playbook with favorite phrases, such as: “not conclusive,” “uncertain,” “scientists disagree,” “lack of consensus.” Disagreement in science is healthy. However, this (very routine) component of science can also become a winning political strategy used against science and public policy. Casting doubt can delay regulation.
Naomi Oreskes writes in Merchants of Doubt, “The industry had realized you could create the impression of controversy simply by asking questions.” That’s why our concern isn’t that researchers are debating methods. Our concern is that sensational headlines can warp debate, and give merchants of doubt an opportunity to skew public perception.
We’re not asking journalists to avoid urgency. Plastic pollution is urgent. Certain phrases, however, may signal that you’re being pulled into a pattern of mythmaking, such as “bombshell,” or “debunked,” when what’s really happening is refinement. Those phrases shock and entertain, but do little to foster understanding.
What we actually need next is for the microplastics field to keep growing. Researchers across the board—from those that think studies are exaggerated to those that stand behind their research findings—are making calls for better lab protocols, contamination controls, reporting requirements, and inter-lab studies to validate results. These are unglamorous, but they’re what solidify early research findings into trusted science. A first-of-its-kind finding of plastic somewhere in the human body shouldn’t be framed like the final truth. It should be heralded as the beginning of a more complete picture.
His new dietary guidelines promoting saturated fats are a recipe for disaster, and a heart attack.
Fat is now phat, at least according to Robert F. Kennedy Jr.
When President Donald Trump’s Health and Human Services (HHS) secretary unveiled new federal dietary guidelines this January, he declared: “We are ending the war on saturated fats.” Seconding Kennedy was Food and Drug Administration Commissioner Marty Makary, who promised that children and schools will no longer need to “tiptoe” around fat.
Kennedy’s exaltation of fat comes complete with a new upside-down guidelines pyramid where a thick cut of steak and a wedge of cheese share top billing with fruit and vegetables. This prime placement of a prime cut is the strongest endorsement for consuming red meat since the government first issued dietary guidelines in 1980.
The endorsement reverses decades of advisories, which the US Department of Agriculture (USDA) and HHS jointly issue every five years, to limit red meat consumption issued under both Democratic and Republican administrations given the strong evidence that eating less of it lowers the risk of cardiovascular disease. Multiple studies over the last decade have linked red and processed meats not only to cardiovascular disease, but also to colon polyps, colorectal cancer, diabetes, diverticulosis, pneumonia, and even premature death.
Given the scientific evidence, we should intensify the war against saturated fats, not call it off.
The new dietary guidelines even contradict those issued under the first Trump administration just five years ago, warning Americans not to eat too much saturated fat. “There is little room,” those guidelines stated, “to include additional saturated fat in a healthy dietary pattern.” A significant percentage of saturated fat comes from red meat. Americans, who account for only 4% of the people on the planet, consume 21% of the world’s beef.
Kennedy’s fatmania even extends to beef tallow and butter, which the new pyramid identifies—along with olive oil—as “healthy fats” for cooking. In fact, beef tallow is 50% saturated fat. Butter is nearly 70%. Olive oil, meanwhile, is just 14% saturated fat and is, indeed, healthy.
This rendering of recommended fats muddles a message that could have been stunningly refreshing, given the Trump administration’s penchant for meddling with science. Some of the new pyramid’s recommendations were applauded by mainstream health advocacy groups, particularly one advising Americans to consume no more than 10 grams of added sugar per meal and others, as Kennedy pointed out, calling for people to “prioritize whole, nutrient-dense foods—protein, dairy, vegetables, fruits, healthy fats, and whole grains—and dramatically reduce highly processed foods.”
But such wholesomeness could easily be wasted if Americans increase their meat consumption. That would not, as Kennedy professes, make America healthy again. Given the scientific evidence, we should intensify the war against saturated fats, not call it off.
The 420-page report by the Dietary Guidelines Advisory Committee prepared in 2024 for the USDA and HHS found that more than 80% of Americans consume more than the recommended daily limit of saturated fat, which is about 20 grams—10% of a 2,000 calorie-per-day diet. The report concluded that replacing butter with plant-based oils and spreads higher in unsaturated fat is associated with lower cardiovascular disease risk and eating plant-based foods instead of meat is “associated with favorable cardiovascular outcomes.”
A March 2025 peer-reviewed study in JAMA Internal Medicine came to a similar conclusion. It found that eating more butter was associated with a higher risk of cardiovascular disease and cancer. Using plant-based oils instead of butter, the researcher found, was associated with a 17% lower risk of death. Such a reduction in mortality, according to study co-author Dr. Daniel Wang, means “a substantial number of deaths from cancer or from other chronic diseases … could be prevented” by replacing butter with such plant-based oils as soybean or olive oil.
What does a “substantial” number of deaths look like? Heart disease is the No. 1 killer in the United States, and heart disease and stroke kill more people than all cancers and accidents combined. The annual number of American deaths tied to cardiovascular disease is creeping toward the million mark. According to the American Heart Association (AHA), it killed more than 940,000 people in 2022.
Over the next 25 years, AHA projects that the incidence of high blood pressure among adults will increase from 50% today to 61%, obesity rates will jump from 43% to 60% and diabetes will afflict nearly 27% of Americans compared to 16% today. Reducing mortality by 17% for those and other related health problems would go a long way to make Americans healthier.
A good place to begin reducing food-related mortality is by cutting highly processed foods out of the American diet. That would require a drastic change in eating habits for a lot of people. A July 2022 study found that nearly 60% of calories in the average American diet comes from ultra-processed foods, which have been linked to cancer, cardiovascular disease, depression, diabetes, and obesity.
One of the main culprits is fast food. A January 2025 study of the six most popular fast-food chains in the country—Chick-fil-A, Domino’s Pizza, McDonald’s, Starbucks, Subway and Taco Bell—found that 85% of their menu items were ultra-processed. And, according to a 2018 study, more than a third of US adults dine at a fast-food chain on any given day, including nearly half of those aged 20 to 39.

Our overreliance on fast food presents a huge conundrum. US food systems are structured in a way that it is unlikely you can tell people to cut processed foods and eat more meat at the same time. Hamburgers and processed deli meat are among the main ways Americans consume red meat. And given the blizzard of TV ads for junk food and fast-food joints, which have proliferated across the country and especially in low-income food deserts—it is also unlikely that many people will use the new guidelines to comb through their local grocer’s meat department for the leanest (and often most expensive) cut of beef.
According to the University of Connecticut’s Rudd Center for Food Policy and Health, food, beverage, and restaurant companies spend $14 billion a year on advertising in the United States. More than 80% of those ad buys are for fast food, sugary drinks, candy, and unhealthy snacks. That $14 billion is also 10 times more than the $1.4 billion fiscal year 2024 budget for chronic disease and health promotion at the Centers for Disease Control and Prevention. And don’t expect the CDC to get into an arms race with junk food advertisers any time soon. Kennedy slashed the CDC staff by more than 25%, from 13,500 to below 10,000.
All of this adds up to the probability that Americans will see the new guidelines’ recommendation to eat red meat as a green light to gorge on even more burgers and other fast-food, ultra-processed meat.
The new guidelines’ green light for consuming red meat and saturated fats is particularly vexing given the guidelines produced five years ago during Trump’s first term did not promote them. Why the about-face?
During the run-up to Trump’s second term, the agribusiness industry went into overdrive to install Trump in the White House and more Republicans in Congress. In 2016, agribusinesses gave Trump $4.6 million for his campaign, nearly double what it gave Hillary Clinton. But in 2024, they gave Trump $24.2 million, five times what it gave Kamala Harris. Agribusinesses also donated $1 million to Kennedy’s failed 2024 campaign, making him the fourth-biggest recipient among all presidential candidates during that election cycle.
Robert F. Kennedy Jr. is nowhere near making America healthy again by declaring in his new food pyramid that red meat is as healthy as broccoli, tomatoes, and beans.
Despite claiming he wanted dietary guidelines “free from ideological bias, institutional conflicts, or predetermined conclusions,” Kennedy rejected the recommendations of the Dietary Guidelines Advisory Committee and turned over the nation’s dietary data to 9 review authors, at least 6 of whom had financial ties to the beef, dairy, infant-formula, or weight-loss industry.
Three of them have received either research grant funding, honoraria, or consulting fees from the National Cattlemen’s Beef Association, which is known for funding dubious research downplaying or dismissing independent scientific findings that show read meat to be threat to public health and the environment. In 2024, the trade group gave nearly all of its $1.1 million in campaign contributions to Republican committees and candidates.
Kim Brackett, an Idaho rancher and vice president of the beef industry trade group, hailed the new guidelines, claiming “it is easy to incorporate beef into a balanced, heart-healthy diet.”
Perhaps, but the grim reality is most Americans do not follow a balanced, heart-healthy diet. Four out of five of us are already consuming more than the recommended daily limit of saturated fat and we are well on our way to a 60% obesity rate.
So, Robert F. Kennedy Jr. is nowhere near making America healthy again by declaring in his new food pyramid that red meat is as healthy as broccoli, tomatoes, and beans. Beholden to Big Beef, he is driving us full speed ahead on the road to a collective heart attack.
