Neil deGrasse Tyson Wants Celebrities to Promote Scientists
"President Kennedy was the first president to not wear a hat. Have you seen men wearing hats since then?" Neil deGrasse Tyson, one of the world's few astrophysicists with a household name, asks on the phone from his car. Well, no. "If I wear some cowboy hats, it's because it's the outfit, it's not because that's my standard equipment when I leave the home."
"We have classes on 100 things and none of them are on the ability to distinguish what is true and what is not."
But Tyson, who speaks in methodically reasoned paragraphs with lots of semi-rhetorical questions to make sure we're all still listening, isn't really making a point about Mad Men-era men's clothing trends. "Should a president influence fashion?" he says. "I think people sometimes don't know the full power they have over other people. So, that's the first prong in this comment. My second prong is, why would anyone take medical advice from a politician?"
Days before our conversation, news broke that President Trump said he was taking hydroxychloroquine, which he had hyped for months as a surefire magical cure for COVID-19 — the science just hadn't caught up to his predictions. But the science never did catch up; instead, it went the opposite direction, showing that hydroxychloroquine, when used to treat COVID-19 patients, actually led to an increased risk of death.
Alarm spread swiftly around the globe as experts cast the president's professed self-medicating as illogical and dangerous. However, it was just one of a series of wild pieces of medical advice espoused by Trump from his mighty pulpit, like that, hey, maybe disinfectants could cure people when injected into their bodies. (That also leads to death.)
But people do take medical advice from politicians. An Arizona man afraid of COVID-19 died after consuming chloroquine phosphate, which he and his wife had sitting on the back of a shelf after using it to treat koi fish for parasites. The pandemic has exposed many weaknesses in the feedback loop of society, government, the media, and science, including the difficulty of seeding accurate medical information with the masses. Many on the left and right decry a broken political and news media system, but Tyson believes the problem isn't mega-influencers like Trump. Rather it's the general public's desire to take their advice on complex topics – like the science of virology – that such influencers know nothing about.
Tyson's not upset with the public, who follow Trump's advice. "As an educator, I can't get angry with you," he says. Or even Trump himself. "Trump was elected by 60 million people, right? So, you could say all you want about Trump, kick him out of office, whatever. [There's] still the 60 million fellow Americans who walk among us who voted for him. So, what are you going to do with them?"
Tyson also isn't upset with Facebook, Twitter, and other social platforms that serve as today's biggest conduits for misinformation. After all, in the realm of modern media's history, these networks are tadpoles. "As an educator and as a scientist, I'm leaning towards, let's figure out a way to train people in school to not fall victim to false information, and how to judge what is likely to be false relative to what is likely to be true. And that's hard, but you and I have never had a class in that, have we? We've had biology classes, we've had English lit, we've had classes on Shakespeare — we have classes on 100 things and none of them are on the ability to distinguish what is true and what is not."
This is why Tyson himself doesn't engage in Trump bashing on his social feeds, but does try to get people to differentiate factual science from fake news. "I feel responsibility to participate in the enlightenment of culture and of civilization, because I have that access," says Tyson, who has 13.9M followers on Twitter, 1.2M on Instagram, and 4.2M on Facebook. He doesn't tell his followers not to inject themselves with Clorox ("no one likes being told what to do"), but tries to get them to visualize a pandemic's impact by comparing it to, say, a throng of rabbits.
"Left unchecked, 1,000 rabbits in 5 years, become 7-billion, the human population of the World. After 15 years, a 'land-ocean' of rabbits fills to one-kilometer depth across all of Earth's continents. Viruses can reproduce waaaay faster than Rabbits," he tweeted on April 6, after much of the nation had locked down to slow the pandemic's spread. For added viral impact, he attached a photo of an adorable, perhaps appropriately scared-looking, white bunny.
Of course, not all celebrities message responsibly.
Tyson is a rare scientist-turned-celebrity. His appeal isn't acting in movies or singing dance-pop anthems (if only). Rather, his life's work is making science fun and interesting to as many people as possible through his best-selling books on astrophysics and his directorship of the planetarium at the American Museum of Natural History in New York. His longstanding place in popular culture is an exception, not the rule.
And he believes his fellow celebrities, actors and pop music stars and internet influencers, should aid the public's quest for accurate scientific information. And in order to do that, they must point their followers to experts and organizations who know what they're talking about. "It could be to a website, it could be to a talk that was given. I would say that that's where the responsibility lies if you control the interests of a million people," he says.
One example of this is Lady Gaga's March 14 Instagram of herself on her couch with her three dogs with the caption, "So I talked to some doctors and scientists. It's not the easiest for everyone right now but the kindest/healthiest thing we can do is self-quarantine and not hang out with people over 65 and in large groups. I wish I could see my parents and grandmas right now but it's much safer to not so I don't get them sick in case I have it. I'm hanging at home with my dogs." (All the celebrities here in this article are my references, not Tyson's, who does not call out specific people.)
Of course, not all celebrities message responsibly. Jessica Biel and Jenny McCarthy have faced scorn for public stances against vaccines. Gwyneth Paltrow and her media brand GOOP have faced backlash for promoting homeopathic treatments with no basis in science.
"The New Age Movement is a cultural idea, it has nothing to do with religion, has nothing to do with politics, and it's people who were rejecting objectively established science in part or in total because they have a belief system that they want to attach to it, okay? This is how you get the homeopathic remedies," says Tyson. "That's why science exists, so that we don't have to base decisions on belief systems."

Last week, researchers at the University of Oxford announced that they have received funding to create a brand new way of preventing ovarian cancer: A vaccine. The vaccine, known as OvarianVax, will teach the immune system to recognize and destroy mutated cells—one of the earliest indicators of ovarian cancer.
Understanding Ovarian Cancer
Despite advancements in medical research and treatment protocols over the last few decades, ovarian cancer still poses a significant threat to women’s health. In the United States alone, more than 12,0000 women die of ovarian cancer each year, and only about half of women diagnosed with ovarian cancer survive five or more years past diagnosis. Unlike cervical cancer, there is no routine screening for ovarian cancer, so it often goes undetected until it has reached advanced stages. Additionally, the primary symptoms of ovarian cancer—frequent urination, bloating, loss of appetite, and abdominal pain—can often be mistaken for other non-cancerous conditions, delaying treatment.
An American woman has roughly a one percent chance of developing ovarian cancer throughout her lifetime. However, these odds increase significantly if she has inherited mutations in the BRCA1 or BRCA2 genes. Women who carry these mutations face a 46% lifetime risk for ovarian and breast cancers.
An Unlikely Solution
To address this escalating health concern, the organization Cancer Research UK has invested £600,000 over the next three years in research aimed at creating a vaccine, which would destroy cancerous cells before they have a chance to develop any further.
Researchers at the University of Oxford are at the forefront of this initiative. With funding from Cancer Research UK, scientists will use tissue samples from the ovaries and fallopian tubes of patients currently battling ovarian cancer. Using these samples, University of Oxford scientists will create a vaccine to recognize certain proteins on the surface of ovarian cancer cells known as tumor-associated antigens. The vaccine will then train that person’s immune system to recognize the cancer markers and destroy them.
The next step
Once developed, the vaccine will first be tested in patients with the disease, to see if their ovarian tumors will shrink or disappear. Then, the vaccine will be tested in women with the BRCA1 or BRCA2 mutations as well as women in the general population without genetic mutations, to see whether the vaccine can prevent the cancer altogether.
While the vaccine still has “a long way to go,” according to Professor Ahmed Ahmed, Director of Oxford University’s ovarian cancer cell laboratory, he is “optimistic” about the results.
“We need better strategies to prevent ovarian cancer,” said Ahmed in a press release from the University of Oxford. “Currently, women with BRCA1/2 mutations are offered surgery which prevents cancer but robs them of the chance to have children afterward.
Teaching the immune system to recognize the very early signs of cancer is a tough challenge. But we now have highly sophisticated tools which give us real insights into how the immune system recognizes ovarian cancer. OvarianVax could offer the solution.”
How sharing, hearing, and remembering positive stories can help shape our brains for the better
Across cultures and through millennia, human beings have always told stories. Whether it’s a group of boy scouts around a campfire sharing ghost stories or the paleolithic Cro-Magnons etching pictures of bison on cave walls, researchers believe that storytelling has been universal to human beings since the development of language.
But storytelling was more than just a way for our ancestors to pass the time. Researchers believe that storytelling served an important evolutionary purpose, helping humans learn empathy, share important information (such as where predators were or what berries were safe to eat), as well as strengthen social bonds. Quite literally, storytelling has made it possible for the human race to survive.
Today, neuroscientists are discovering that storytelling is just as important now as it was millions of years ago. Particularly in sharing positive stories, humans can more easily form relational bonds, develop a more flexible perspective, and actually grow new brain circuitry that helps us survive. Here’s how.
How sharing stories positively impacts the brain
When human beings share stories, it increases the levels of certain neurochemicals in the brain, neuroscientists have found. In a 2021 study published in Proceedings of the National Academy of Sciences (PNAS), Swedish researchers found that simply hearing a story could make hospitalized children feel better, compared to other hospitalized children who played a riddle game for the same amount of time. In their research, children in the intensive care unit who heard stories for just 30 minutes had higher levels of oxytocin, a hormone that promotes positive feelings and is linked to relaxation, trust, social connectedness, and overall psychological stability. Furthermore, the same children showed lower levels of cortisol, a hormone associated with stress. Afterward, the group of children who heard stories tended to describe their hospital experiences more positively, and even reported lower levels of pain.
Annie Brewster, MD, knows the positive effect of storytelling from personal experience. An assistant professor at Harvard Medical School and the author of The Healing Power of Storytelling: Using Personal Narrative to Navigate Illness, Trauma, and Loss, Brewster started sharing her personal experience with chronic illness after being diagnosed with multiple sclerosis in 2001. In doing so, Brewster says it has enabled her to accept her diagnosis and integrate it into her identity. Brewster believes so much in the power of hearing and sharing stories that in 2013 she founded Health Story Collaborative, a forum for others to share their mental and physical health challenges.“I wanted to hear stories of people who had found ways to move forward in positive ways, in spite of health challenges,” Brewster said. In doing so, Brewster believes people with chronic conditions can “move closer to self-acceptance and self-love.”
While hearing and sharing positive stories has been shown to increase oxytocin and other “feel good” chemicals, simply remembering a positive story has an effect on our brains as well. Mark Hoelterhoff, PhD, a lecturer in clinical psychology at the University of Edinburgh, recalling and “savoring” a positive story, thought, or feedback “begins to create new brain circuitry—a new neural network that’s geared toward looking for the positive,” he says. Over time, other research shows, savoring positive stories or thoughts can literally change the shape of your brain, hard-wiring someone to see things in a more positive light.How stories can change your behavior
In 2009, Paul Zak, PhD, a neuroscientist and professor at Claremont Graduate University, set out to measure how storytelling can actually change human behavior for the better. In his study, Zak wanted to measure the behavioral effects of oxytocin, and did this by showing test subjects two short video clips designed to elicit an emotional response.
In the first video they showed the study participants, a father spoke to the camera about his two-year-old son, Ben, who had been diagnosed with terminal brain cancer. The father told the audience that he struggled to connect with and enjoy Ben, as Ben had only a few months left to live. In the end, the father finds the strength to stay emotionally connected to his son until he dies.
The second video clip, however, was much less emotional. In that clip, the same father and son are shown spending the day at the zoo. Ben is only suggested to have cancer (he is bald from chemotherapy and referred to as a ‘miracle’, but the cancer isn’t mentioned directly). The second story lacked the dramatic narrative arc of the first video.
Zak’s team took blood before and after the participants watched one of the two videos and found that the first story increased the viewers’ cortisol and oxytocin, suggesting that they felt distress over the boy’s diagnosis and empathy toward the boy and his father. The second narrative, however, didn’t increase oxytocin or cortisol at all.
But Zak took the experiment a step further. After the movie clips, his team gave the study participants a chance to share money with a stranger in the lab. The participants who had an increase in cortisol and oxytocin were more likely to donate money generously. The participants who had increased cortisol and oxytocin were also more likely to donate money to a charity that works with children who are ill. Zak also found that the amount of oxytocin that was released was correlated with how much money people felt comfortable giving—in other words, the more oxytocin that was released, the more generous they felt, and the more money they donated.
How storytelling strengthens our bond with others
Sharing, hearing, and remembering stories can be a powerful tool for social change–not only in the way it changes our brain and our behavior, but also because it can positively affect our relationships with other people
Emotional stimulation from telling stories, writes Zak, is the foundation for empathy, and empathy strengthens our relationships with other people. “By knowing someone’s story—where they come from, what they do, and who you might know in common—relationships with strangers are formed.”
But why are these relationships important for humanity? Because human beings can use storytelling to build empathy and form relationships, it enables them to “engage in the kinds of large-scale cooperation that builds massive bridges and sends humans into space,” says Zak.
Storytelling, Zak found, and the oxytocin release that follows, also makes people more sensitive to social cues. This sensitivity not only motivates us to form relationships, but also to engage with other people and offer help, particularly if the other person seems to need help.
But as Zak found in his experiments, the type of storytelling matters when it comes to affecting relationships. Where Zak found that storytelling with a dramatic arc helps release oxytocin and cortisol, enabling people to feel more empathic and generous, other researchers have found that sharing happy stories allows for greater closeness between individuals and speakers. A group of Chinese researchers found that, compared to emotionally-neutral stories, happy stories were more “emotionally contagious.” Test subjects who heard happy stories had greater activation in certain areas of their brains, experienced more significant, positive changes in their mood, and felt a greater sense of closeness between themselves and the speaker.
“This finding suggests that when individuals are happy, they become less self-focused and then feel more intimate with others,” the authors of the study wrote. “Therefore, sharing happiness could strengthen interpersonal bonding.” The researchers went on to say that this could lead to developing better social networks, receiving more social support, and leading more successful social lives.
Since the start of the COVID pandemic, social isolation, loneliness, and resulting mental health issues have only gotten worse. In light of this, it’s safe to say that hearing, sharing, and remembering stories isn’t just something we can do for entertainment. Storytelling has always been central to the human experience, and now more than ever it’s become something crucial for our survival.
