American politics has no shortage of ailments. Many do not feel like their voice matters amid the money and influence amassed by corporations and wealthy donors. Many doubt whether elected officials and bureaucrats can or even want to effectively solve problems and respond to citizens' needs. Many feel divided both physically and psychologically, and uncomfortable (if not scared) at the prospect of building new connections across lines of difference.
Strengthening American democracy requires countering these trends. New collaborations between university researchers and community leaders such as elected officials, organizers, and nonprofit directors can help. These collaborations can entail everything from informal exchanges to co-led projects.
But there's a catch. They require that people with diverse forms of knowledge and lived experience, who are often strangers, choose to engage with one another. We know that strangers often remain strangers.
That's why a science of collaboration that centers the inception question is vital: When do diverse individuals choose to work together in the first place? How can we design institutions that encourage beneficial collaborations to arise and thrive? And what outcomes can occur?
How Collaborations Between Researchers and Community Leaders Can Help
First consider the feeling of powerlessness. Individual action becomes more powerful when part of a collective. For ordinary citizens, voting and organizing are arguably the two most impactful forms of collective action, and as it turns out there is substantial research on how to increase turnout and how to build powerful civic associations. Collaborations between researchers familiar with that work and organizers and nonprofit leaders familiar with a community's context can be especially impactful.
For example, in 2019, climate organizers with a nonpartisan group in North Carolina worked with a researcher who studies organizing to figure out how to increase volunteer commitment—that is, how to transform volunteers who only attend meetings into leaders who take responsibility for organizing others. Together, they designed strategies that made sense for the local area. Once implemented, these strategies led to a 161% year-over-year increase in commitment. More concretely, dozens of newly empowered volunteers led events to raise awareness of how climate change was impacting the local community and developed relationships with local officials and business owners, all while coming to see themselves as civic leaders. This experience also fed back into the researcher's work, motivating the design of future studies.
Or consider how researchers and local elected officials can collaborate and respond to novel challenges like the coronavirus. For instance, in March 2020, one county in Upstate New York suddenly had to figure out how to provide vital services like internet and health screenings for residents who could no longer visit shuttered county offices. They turned to a researcher who knew about research on mobile vans. Together, they spoke about the benefits and costs of mobile vans in general, and then segued into a more specific conversation about what routings and services would make sense in this specific locale. Their collaboration entailed a few conversations leading up to the county's decision, and in the end the county received helpful information and the researcher learned about new implementation challenges associated with mobile vans.
In April, legislators in another Upstate New York county realized they needed honest, if biting, feedback from local mayors about their response to the pandemic. They collaborated with researchers familiar with survey methodology. County legislators supplied the goals and historical information about fraught county–city relationships, while researchers supplied evidence-based techniques for conducting interviews in delicate contexts. These interviews ultimately revealed mayors' demand for more up-to-date coronavirus information from the county and also more county-led advocacy at the state level.
To be sure, there are many situations in which elected officials' lack of information is not the main hurdle. Rather, they need an incentive to act. Yet this is another situation in which collaborations between university researchers and community leaders focused on evidence-based, context-appropriate approaches to organizing and voter mobilization could produce needed pressure.
This brings me to the third way in which collaborations between researchers and community leaders can strengthen American democracy. They entail diverse people working to develop a common interest by building new connections across lines of difference. This is a core democratic skill that withers in the absence of practice.
In addition to credibility, we've learned that potential collaborators also care about whether others will be responsive to their goals and constraints, understand their point of view, and will be enjoyable to interact with.
The Science of Collaboration
The previous examples have one thing in common: a collaboration actually took place.
Yet that often does not happen. While there are many reasons why collaborations between diverse people should arise we know far less about when they actually do arise.
This is why a science of collaboration centered on inception is essential. Some studies have already revealed new insights. One thing we've learned is that credibility is important, but often not enough. By credibility, I mean that people are more likely to collaborate when they perceive each other to be trustworthy and have useful information or skills to share. Potential collaborators can signal their credibility by, for instance, identifying shared values and mentioning relevant previous experiences. One study finds that policymakers are more interested in collaborating with researchers who will share findings that are timely and locally relevant—that is, the kind that are most useful to them.
In addition to credibility, we've learned that potential collaborators also care about whether others will be responsive to their goals and constraints, understand their point of view, and will be enjoyable to interact with. For instance, potential collaborators can explicitly acknowledge that they know the other person is busy, or start with a question rather than a statement to indicate being interested. One study finds that busy nonprofit leaders are more likely to collaborate with researchers who explicitly state that (a) they are interested in learning about the leaders' expertise, and (b) they will efficiently share what they know. Another study underscores that potential collaborators need to feel like they know how to interact—that is, to feel like they have a "script" for what's appropriate to say during the interaction.
We're also learning that institutions (such as matchmaking organizations) can reduce uncertainty about credibility and relationality, and also help collaborations start off on the right foot. They are a critical avenue for connecting strangers. For instance, brokers can use techniques that increase the likelihood that diverse people feel comfortable sharing what they know, raising concerns, and being responsive to others.
Looking Ahead
A science of collaboration that centers the inception question is helpful on two levels. First, it provides an evidence base for how to effectively connect diverse people to work together. Second, when applied to university researchers and community leaders, it can produce collaborations that strengthen American democracy. Moreover, these collaborations are easily implemented, especially when informal and beginning as a conversation or two (as in the mobile vans example).
Existing research on the science of collaboration has already yielded actionable insights, yet we still have much to learn. For instance, we need to better understand the latent demand. Interviews that ask a wide variety of community leaders and researchers who have not previously collaborated to talk about why doing so might be helpful would be enlightening. They could also be a useful antidote to the narrative of conflict that often permeates discussions about the role of science in American politics.
In addition, we need to learn more about the downstream consequences of these collaborations, such as whether new networks arise that include colleagues of the initial collaborators. Here, it would be helpful to study the work of brokers – how they introduce people to each other, how much they follow up, and the impact of those decisions.
Ultimately, expanding the evidence base of the science of collaboration, and then directly applying what we learn, will provide important new and actionable avenues for strengthening American democracy.

Gene Transfer Leads to Longer Life and Healthspan
In August, a study provided the first proof-of-principle that genetic material transferred from one species to another can increase both longevity and healthspan in the recipient animal.
The naked mole rat won’t win any beauty contests, but it could possibly win in the talent category. Its superpower: fighting the aging process to live several times longer than other animals its size, in a state of youthful vigor.
It’s believed that naked mole rats experience all the normal processes of wear and tear over their lifespan, but that they’re exceptionally good at repairing the damage from oxygen free radicals and the DNA errors that accumulate over time. Even though they possess genes that make them vulnerable to cancer, they rarely develop the disease, or any other age-related disease, for that matter. Naked mole rats are known to live for over 40 years without any signs of aging, whereas mice live on average about two years and are highly prone to cancer.
Now, these remarkable animals may be able to share their superpower with other species. In August, a study provided what may be the first proof-of-principle that genetic material transferred from one species can increase both longevity and healthspan in a recipient animal.
There are several theories to explain the naked mole rat’s longevity, but the one explored in the study, published in Nature, is based on the abundance of large-molecule high-molecular mass hyaluronic acid (HMM-HA).
A small molecule version of hyaluronic acid is commonly added to skin moisturizers and cosmetics that are marketed as ways to keep skin youthful, but this version, just applied to the skin, won’t have a dramatic anti-aging effect. The naked mole rat has an abundance of the much-larger molecule, HMM-HA, in the chemical-rich solution between cells throughout its body. But does the HMM-HA actually govern the extraordinary longevity and healthspan of the naked mole rat?
To answer this question, Dr. Vera Gorbunova, a professor of biology and oncology at the University of Rochester, and her team created a mouse model containing the naked mole rat gene hyaluronic acid synthase 2, or nmrHas2. It turned out that the mice receiving this gene during their early developmental stage also expressed HMM-HA.
The researchers found that the effects of the HMM-HA molecule in the mice were marked and diverse, exceeding the expectations of the study’s co-authors. High-molecular mass hyaluronic acid was more abundant in kidneys, muscles and other organs of the Has2 mice compared to control mice.
In addition, the altered mice had a much lower incidence of cancer. Seventy percent of the control mice eventually developed cancer, compared to only 57 percent of the altered mice, even after several techniques were used to induce the disease. The biggest difference occurred in the oldest mice, where the cancer incidence for the Has2 mice and the controls was 47 percent and 83 percent, respectively.
With regard to longevity, Has2 males increased their lifespan by more than 16 percent and the females added 9 percent. “Somehow the effect is much more pronounced in male mice, and we don’t have a perfect answer as to why,” says Dr. Gorbunova. Another improvement was in the healthspan of the altered mice: the number of years they spent in a state of relative youth. There’s a frailty index for mice, which includes body weight, mobility, grip strength, vision and hearing, in addition to overall conditions such as the health of the coat and body temperature. The Has2 mice scored lower in frailty than the controls by all measures. They also performed better in tests of locomotion and coordination, and in bone density.
Gorbunova’s results show that a gene artificially transferred from one species can have a beneficial effect on another species for longevity, something that had never been demonstrated before. This finding is “quite spectacular,” said Steven Austad, a biologist at the University of Alabama at Birmingham, who was not involved in the study.
Just as in lifespan, the effects in various organs and systems varied between the sexes, a common occurrence in longevity research, according to Austad, who authored the book Methuselah’s Zoo and specializes in the biological differences between species. “We have ten drugs that we can give to mice to make them live longer,” he says, “and all of them work better in one sex than in the other.” This suggests that more attention needs to be paid to the different effects of anti-aging strategies between the sexes, as well as gender differences in healthspan.
According to the study authors, the HMM-HA molecule delivered these benefits by reducing inflammation and senescence (cell dysfunction and death). The molecule also caused a variety of other benefits, including an upregulation of genes involved in the function of mitochondria, the powerhouses of the cells. These mechanisms are implicated in the aging process, and in human disease. In humans, virtually all noncommunicable diseases entail an acceleration of the aging process.
So, would the gene that creates HMM-HA have similar benefits for longevity in humans? “We think about these questions a lot,” Gorbunova says. “It’s been done by injections in certain patients, but it has a local effect in the treatment of organs affected by disease,” which could offer some benefits, she added.
“Mice are very short-lived and cancer-prone, and the effects are small,” says Steven Austad, a biologist at the University of Alabama at Birmingham. “But they did live longer and stay healthy longer, which is remarkable.”
As for a gene therapy to introduce the nmrHas2 gene into humans to obtain a global result, she’s skeptical because of the complexity involved. Gorbunova notes that there are potential dangers in introducing an animal gene into humans, such as immune responses or allergic reactions.
Austad is equally cautious about a gene therapy. “What this study says is that you can take something a species does well and transfer at least some of that into a new species. It opens up the way, but you may need to transfer six or eight or ten genes into a human” to get the large effect desired. Humans are much more complex and contain many more genes than mice, and all systems in a biological organism are intricately connected. One naked mole rat gene may not make a big difference when it interacts with human genes, metabolism and physiology.
Still, Austad thinks the possibilities are tantalizing. “Mice are very short-lived and cancer-prone, and the effects are small,” he says. “But they did live longer and stay healthy longer, which is remarkable.”
As for further research, says Austad, “The first place to look is the skin” to see if the nmrHas2 gene and the HMM-HA it produces can reduce the chance of cancer. Austad added that it would be straightforward to use the gene to try to prevent cancer in skin cells in a dish to see if it prevents cancer. It would not be hard to do. “We don’t know of any downsides to hyaluronic acid in skin, because it’s already used in skin products, and you could look at this fairly quickly.”
“Aging mechanisms evolved over a long time,” says Gorbunova, “so in aging there are multiple mechanisms working together that affect each other.” All of these processes could play a part and almost certainly differ from one species to the next.
“HMM-HA molecules are large, but we’re now looking for a small-molecule drug that would slow it’s breakdown,” she says. “And we’re looking for inhibitors, now being tested in mice, that would hinder the breakdown of hyaluronic acid.” Gorbunova has found a natural, plant-based product that acts as an inhibitor and could potentially be taken as a supplement. Ultimately, though, she thinks that drug development will be the safest and most effective approach to delivering HMM-HA for anti-aging.
A new study provides key insights in what causes Alzheimer's: a breakdown in the brain’s system for clearing waste.
In recent years, researchers of Alzheimer’s have made progress in figuring out the complex factors that lead to the disease. Yet, the root cause, or causes, of Alzheimer’s are still pretty much a mystery.
In fact, many people get Alzheimer’s even though they lack the gene variant we know can play a role in the disease. This is a critical knowledge gap for research to address because the vast majority of Alzheimer’s patients don’t have this variant.
A new study provides key insights into what’s causing the disease. The research, published in Nature Communications, points to a breakdown over time in the brain’s system for clearing waste, an issue that seems to happen in some people as they get older.
Michael Glickman, a biologist at Technion – Israel Institute of Technology, helped lead this research. I asked him to tell me about his approach to studying how this breakdown occurs in the brain, and how he tested a treatment that has potential to fix the problem at its earliest stages.
Dr. Michael Glickman is internationally renowned for his research on the ubiquitin-proteasome system (UPS), the brain's system for clearing the waste that is involved in diseases such as Huntington's, Alzheimer's, and Parkinson's. He is the head of the Lab for Protein Characterization in the Faculty of Biology at the Technion – Israel Institute of Technology. In the lab, Michael and his team focus on protein recycling and the ubiquitin-proteasome system, which protects against serious diseases like Alzheimer’s, Parkinson’s, cystic fibrosis, and diabetes. After earning his PhD at the University of California at Berkeley in 1994, Michael joined the Technion as a Senior Lecturer in 1998 and has served as a full professor since 2009.
