These scientists think an 'awe'-some eclipse could help unite Americans in troubled times
To hear Herodotus tell it, a total solar eclipse in 585 BC ended a five-year war between ancient kingdoms in present-day Turkey.
Could another total eclipse on Monday bring an end to the partisan wars in America?
The idea may sound far-fetched — until you talk with Paul Piff. The UC Irvine professor of psychology and social behavior has spent the better part of two decades researching what triggers us to set our personal needs aside and shift our focus to the greater good.
One of them, he and other scholars have found, is awe: the feeling you get when you contemplate something that is so vast and so mysterious that it forces you to reevaluate your understanding of the world.
And few things generate awe like watching the moon blot out the sun and plunge a sunny day into erie darkness.
“People talk about eclipses as one of the coolest or most mind-blowing things they’ve ever seen,” Piff said.

For the Great American Eclipse of 2017, Piff launched a research study that showed people engulfed by the moon’s shadow experienced more awe than their counterparts who didn’t see the sun disappear. What’s more, that sense of awe seemed to make them feel more in touch with others, more open to differing points of view, and more inclined to put someone else’s needs ahead of their own.
Piff is of the opinion that the country could use more of those sentiments this year, as a contentious presidential race threatens to turn political opponents into sworn enemies.
Awe “gives you a sense of feeling connected to something bigger than yourself, like your community, your society or your world,” he said. “Getting people to feel that way is totally vital to our species’ survival and longevity.”
Monday’s eclipse offers a fresh opportunity to assess the emotional states of the tens of millions of Americans who are expected to gather in the path of totality. Piff plans to focus on whether the celestial event will make those who experience it feel more allied with their fellow Americans who belong to a rival political party.

Jennifer Stellar, a social psychologist who studies emotions at the University of Toronto, sees reason for optimism. She said awe is an ideal tool for trying to reduce political polarization.
Emotions like gratitude and compassion tend to pull one’s focus outward, but in those cases it’s usually redirected toward a single person, she said. Awe is unique in that “it creates a sense of interconnection, of common humanity, of collective interest.”
The community-oriented mind-set documented in the wake of the 2017 eclipse wore off within six weeks, Piff and his collaborators found.
What would it take to make it last?
If you’ve ever found yourself mired in an anger spiral, paralyzed with fear or overwhelmed by debilitating grief, you may have wondered what emotions are good for. Experts assure they serve a useful purpose.
“Negative emotions narrow your attention, get you to focus on threats. Positive emotions broaden your mind,” said psychologist Dacher Keltner, faculty director of the Greater Good Science Center at UC Berkeley.
Keltner’s lab has studied positive feelings like amusement, compassion, gratitude and love. But his favorite emotion is awe. (He even wrote a book about it called “Awe: The New Science of Everyday Wonder and How It Can Transform Your Life.”)
“Awe is destabilizing,” Keltner said. “It makes you realize your knowledge can’t explain everything.”

Awe is also a universal emotion, expressed by people across countries and continents. No matter where we’re from, awe makes us widen our eyes and open our mouths.
The fact that it emerged in so many disparate cultures around the world is one indication of awe’s usefulness, Piff said. What’s more, societies have ritualized ways to get regular hits of awe, whether it’s walking into a majestic church or visiting the Grand Canyon.
When Piff investigates the effects of awe, he prompts study subjects to feel it by asking them to look up into the canopy of a stand of towering eucalyptus trees or by watching a slow-motion video of dye dropping into a glass of milk.
Such research by Piff and many others has found that awe makes us feel breathless, affects our heart rate, and causes goosebumps to rise on our skin. It also reduces physiological signs of stress and suppresses the brain’s default mode network, which plays a role in certain forms of self-focus.
“In all sorts of ways, individuals who experience awe experience a whole bunch of different benefits — better health, better meaning, more happiness, a greater sense of purpose in life,” Piff said.
It also fuels discovery and exploration, Keltner said.
“Awe provides the engine by which you update your knowledge,” he said. “It animates the testing of new ideas. And we need that — we need to always be updating our understanding of the world.”
Keltner has gathered stories about awe from 26 countries to look for common triggers. Nature was one of the broad categories that came up repeatedly, he said, and “big ideas” was another.
A total solar eclipse ticks both of those boxes.

There’s nothing inherently mysterious about the cause of a total solar eclipse.
The moon travels around the Earth as the Earth travels around the sun, though the planes of those orbits are slightly askew. Nonetheless, at least twice a year the moon comes directly between the Earth and the sun, blocking it from view in the daytime sky. And about once every 18 months or so, this celestial alignment occurs while the moon is close enough to Earth to cover the sun completely — in other words, to totally eclipse it.
That seems like a frequent occurrence, but any particular spot on the planet will find itself in the path of totality just once every 375 years, on average. To find oneself in just the right place at just the right time may be awe-inducing all by itself.
The idea of using an eclipse as a natural experiment to study awe came to Piff in 2016, when he attended an “awe summit” and heard a UC Berkeley astronomer mention that the Great American Eclipse of Aug. 21, 2017, would be the first in nearly a century to produce a coast-to-coast path of totality.

It wasn’t immediately clear how to capitalize on the event. He could have dispatched researchers to places along the eclipse’s path so they could observe the crowds or conduct interviews. He could have distributed a survey to people who said they’d witnessed the eclipse and hoped that they would fill it out.
“None of the ideas really stuck,” Piff said.
Ultimately, he turned to Twitter.
Nickolas M. Jones, who was a graduate student at the time, had devised a way to identify Twitter users in a particular community based on the accounts they followed. That allowed him to create a sample of more than 1.5 million tweets shared over a 12-week period by more than 22,000 people in select cities along the path of totality.
Meanwhile, another graduate student named Sean Goldy took the lead in creating a custom dictionary of words that expressed awe — it included “transcendent,” “mind-blowing” and “unreal” — along with terms indicative of the community-focused outlook that awe often inspires. The dictionary was used to assess the emotional subtext of the tweets Jones amassed, as well as a sample of 6 million tweets posted on the day of the eclipse.
The researchers found that Twitter users who were positioned to witness the eclipse were more than twice as likely to use words from the awe dictionary than people who missed out on the big event.
To a lesser degree, they were also more likely to use words that expressed a collective mind-set, recognized the limits of their knowledge, and gave credence to the views of others. The research team’s statistical analysis suggested that these feelings were driven in part by the awe they felt.
In addition, the tweets gathered by Jones showed that people who injected more awe-related words into their eclipse day tweets also used language infused with outward-looking, community-minded sentiments — although the effect was short-lived.
The findings were published in the journal Psychological Science.

Jones, who is now a senior postdoctoral researcher at UC Irvine, said he developed his method of geolocating Twitter users in order to gauge the effect of mass shootings.
“The effect that we find when we study negative events is pretty powerful,” he said. “I was not expecting things to pan out really well for something positive, but … it worked!”
Posts on X, as Twitter is now known, are no longer freely available to researchers. So Piff and a new set of collaborators are devising another way to gather data related to Monday’s eclipse.
They’ve already found people who said they are planning to experience totality somewhere between Mazatlan, Mexico, and Newfoundland and Labrador, Canada. They hope to entice them to answer a few questions on their phones while the world is temporarily dark, and to follow up with them for several weeks afterward.
In other experiments, Piff has had volunteers invest five minutes in a “daily intervention of awe.” Early results suggest it extends the benefits of an initial awesome experience, he said.

“If people become a little more attentive to the awe-inspiring things around them, you would very likely get more persistent effects,” Piff said.
He said he hopes that would include the kind of mind-set shift that could help bridge the country’s increasingly toxic partisan divide.
There’s no reason why an event like the eclipse would cause people to change their party identity, Piff said, but it could make them more willing to compromise with their political opponents for the sake of a collective goal.
“Awe seems to trigger more kind, compassionate and empathic behavior,” he said. “It reminds you of the bigger things that we’re a part of.”

Very little plastic being recycled in California as state efforts falter
California touts itself as a leader on the problem of plastic garbage, but recent developments suggest otherwise.
A new report issued by the state’s waste agency shows plastic yogurt containers, shampoo bottles and restaurant takeout trays are being recycled at rates only in the single digits.

Polypropylene, labeled as #5 on packaging, is used for yogurt containers, margarine tubs and microwavable trays. Only 2% of it is getting recycled. Colored shampoo and detergent bottles, made from polyethylene, or #1 plastic, are getting recycled at a rate of just 5%.
Other plastics, including ones promoted as highly recyclable, such as clear polyethylene bottles, which hold some medications, or hard water bottles, are being recycled at just 16%.
No plastic in the report exceeds a recycling rate of 23%, with the majority reported in just the single digits.
Adding to this disquieting assessment, CalRecycle also just pulled back regulations that were supposed to finalize a landmark single-use plastic law known as Senate Bill 54 — a law designed to make the majority of packaging waste in the state recyclable or compostable by working with the plastic and packaging industries.
The report and delay have sparked a wide variety of reactions by those who have closely watched the law as it was written and implemented.
The proposed regulations were regarded as friendly to industry. As a result, some are hopeful that CalRecycle’s decision to pull them back for tweaking means the agency will make the law stronger. Others say the two developments just show the state has never really been serious about plastic recycling.
“California’s SB 54 … will NEVER increase the recycling rates of these items … because cartons and plastic packaging are fundamentally not technically or economically recyclable,” said Jan Dell, the founder of Orange County-based Last Beach Cleanup, an anti-plastic organization.
Industry representatives are also expressing disappointment, saying the more delays and changes the state makes, the harder it is “for California businesses to comply with the law and implement the resulting changes,” said John Myers, a spokesman for the California Chamber of Commerce, which represents companies that will be affected.
Reports on abysmally low rates of recycling for milk cartons and polystyrene have been widely shared and known. But the newest numbers were still a grim confirmation that there are few options for dealing with these materials.
According to one state analysis, 2.9 million tons of single-use plastic and 171.4 billion single-use plastic components were sold, offered for sale or distributed in California in 2023.
Single-use plastics and plastic waste more broadly are considered a growing environmental and health problem. In recent decades, plastic waste has overwhelmed waterways and oceans, sickening marine life and threatening human health.
Last spring, the Newsom administration was accused of neutering the regulations that CalRecycle had initially proposed to implement the law. The changes excluded all packaging material related to produce, meat, dairy products, dog food, toothpaste, condoms, shampoo and cereal boxes, among other products. These are all products that might fall under the purview of the U.S. Food and Drug Administration and the U.S. Department of Agriculture.
It also opened the door to “alternative” recycling, such as chemical recycling, which environmentalists say is polluting, and was banned in the language of the law.
The waste agency then submitted those draft regulations to the Office of Administrative Law, whose lawyers and staff review proposed regulations to ensure they are “clear, necessary, legally valid, and available to the public” before finalizing them. They were set to release their determination on Friday; CalRecycle pulled the regulations back before the office issued its determination.
Neither the law office nor governor’s office responded to requests for comment.
Melanie Turner, CalRecycle’s spokeswoman, said the agency withdrew its proposed regulations “to make changes … to improve clarity and support successful implementation of the law,” and its revisions were focused on areas that dealt with “food and agricultural commodities.”
California State Sen. Ben Allen (D-Santa Monica), author of the original legislation, called the delay “entirely avoidable” in a statement, but said it would allow CalRecycle an “opportunity to ensure the regulations truly follow the law as it was signed.”
He urged the waste agency and Newsom’s administration not to “allow broad, sweeping exemptions that would undermine the program and increase costs for ratepayers.”
Critics of the watered-down regulations, such as Anja Brandon, the director of plastics policy for the Ocean Conservancy, said she wasn’t surprised by the withdrawal.
The proposed regulations “would have gone beyond CalRecycle’s authority by creating a sweeping categorical exclusion for food and agricultural packaging — effectively a loophole that would have allowed producers to continue putting vast amounts of plastic packaging into the marketplace, completely undermining SB 54’s goals and success,” she said in a text message.
Turner said CalRecycle will conduct a 15-day comment period — although when that begins has not yet been divulged.

Cancer survival rates soar nationwide, but L.A. doctors warn cultural and educational barriers leave some behind
The American Cancer Society’s 2026 Cancer Statistics report, released Tuesday, marks a major milestone for U.S. cancer survival rates. For the first time, the annual report shows that 70% of Americans diagnosed with cancer can expect to live at least five years, compared with just 49% in the mid-1970s.
The new findings, based on data from national cancer records and death statistics from 2015 to 2021, also show promising progress in survival rates for people with the deadliest, most advanced and hardest-to-treat cancers when compared with rates from the mid-1990s. The five-year survival rate for myeloma, for example, nearly doubled (from 32% to 62%). The survival rate for liver cancer tripled (from 7% to 22%), for late-stage lung cancer nearly doubled (from 20% to 37%), and for both melanoma and rectal cancer more than doubled (from 16% to 35% and from 8% to 18%, respectively).
For all cancers, the five-year survival rate more than doubled since the mid-1990s, rising from 17% to 35%.
This also signals a 34% drop in cancer mortality since 1991, translating to an estimated 4.8 million fewer cancer deaths between 1991 and 2023. These significant public health advances result from years of public investment in research, early detection and prevention, and improved cancer treatment, according to the report.
“This stunning victory is largely the result of decades of cancer research that provided clinicians with the tools to treat the disease more effectively, turning many cancers from a death sentence into a chronic disease,” said Rebecca Siegel, senior scientific director at the American Cancer Society and lead author of the report.
As more people survive cancer, there is also a growing focus on the quality of life after treatment. Patients, families and caregivers face physical, financial and emotional challenges. Dr. William Dahut, the American Cancer Society’s chief scientific officer, said that ongoing innovation must go hand in hand with better support services and policies, so all survivors — not just the privileged — can have “not only more days, but better days.”
Indeed, the report also shows that not everyone has benefited equally from the advances of the last few decades. American Indian and Alaska Native people now have the highest cancer death rates in the country, with deaths from kidney, liver, stomach and cervical cancers about double that of white Americans.
Additionally, Black women are more likely to die from breast and uterine cancers than non-Black women — and Black men have the highest cancer rates of any American demographic. The report connects these disparities in survival to long-standing issues such as income inequity and the effects of past discrimination, such as redlining, affecting where people live — forcing historically marginalized populations to be disproportionately exposed to environmental carcinogens.
Dr. René Javier Sotelo, a urologic oncologist at Keck Medicine of USC, notes that the fight against cancer in Southern California, amid long-standing disparities facing vulnerable communities, is very much about overcoming educational, cultural and socioeconomic barriers.
While access to care and insurance options in Los Angeles are relatively robust, many disparities persist because community members often lack crucial information about risk factors, screening and early warning signs. “We need to insist on the importance of education and screening,” Sotelo said. He emphasized that making resources, helplines and culturally tailored materials readily available to everyone is crucial.
He cites penile cancer as a stark example: rates are higher among Latino men in L.A., not necessarily due to lack of access, but because of gaps in awareness and education around HPV vaccination and hygiene.
Despite these persisting inequities, the dramatic nationwide improvement in cancer survival is unquestionably good news, bringing renewed hope to many individuals and families. However, the report also gives a clear warning: Proposed federal cuts to cancer research and health insurance could stop or even undo these important gains.
“We can’t stop now,” warned Shane Jacobson, the American Cancer Society’s chief executive.
“We need to understand that we are not yet there,” Sotelo concurred. ”Cancer is still an issue.”

Clashing with the state, L.A. City moves to adopt lenient wildfire ‘Zone Zero’ regulations
As the state continues multiyear marathon discussions on rules for what residents in wildfire hazard zones must do to make the first five feet from their houses — an area dubbed “Zone Zero” — ember-resistant, the Los Angeles City Council voted Tuesday to start creating its own version of the regulations that is more lenient than most proposals currently favored in Sacramento.
Critics of Zone Zero, who are worried about the financial burden and labor required to comply as well as the detrimental impacts to urban ecosystems, have been particularly vocal in Los Angeles. However, wildfire safety advocates worry the measures endorsed by L.A.’s City Council will do little to prevent homes from burning.
“My motion is to get advice from local experts, from the Fire Department, to actually put something in place that makes sense, that’s rooted in science,” said City Councilmember John Lee, who put forth the motion. “Sacramento, unfortunately, doesn’t consult with the largest city in the state — the largest area that deals with wildfires — and so, this is our way of sending a message.”
Tony Andersen — executive officer of the state’s Board of Forestry and Fire Protection, which is in charge of creating the regulations — has repeatedly stressed the board’s commitment to incorporating L.A.’s feedback. Over the last year, the board hosted a contentious public meeting in Pasadena, walking tours with L.A. residents and numerous virtual workshops and hearings.

Some L.A. residents are championing a proposed fire-safety rule, referred to as “Zone Zero,” requiring the clearance of flammable material within the first five feet of homes. Others are skeptical of its value.
With the state long past its original Jan. 1, 2023, deadline to complete the regulations, several cities around the state have taken the matter into their own hands and adopted regulations ahead of the state, including Berkeley and San Diego.
“With the lack of guidance from the State Board of Forestry and Fire Protection, the City is left in a precarious position as it strives to protect residents, property, and the landscape that creates the City of Los Angeles,” the L.A. City Council motion states.
However, unlike San Diego and Berkeley, whose regulations more or less match the strictest options the state Board of Forestry is considering, Los Angeles is pushing for a more lenient approach.
The statewide regulations, once adopted, are expected to override any local versions that are significantly more lenient.
The Zone Zero regulations apply only to rural areas where the California Department of Forestry and Fire Protection responds to fires and urban areas that Cal Fire has determined have “very high” fire hazard. In L.A., that includes significant portions of Silver Lake, Echo Park, Brentwood and Pacific Palisades.
Fire experts and L.A. residents are generally fine with many of the measures within the state’s Zone Zero draft regulations, such as the requirement that there be no wooden or combustible fences or outbuildings within the first five feet of a home. Then there are some measures already required under previous wildfire regulations — such as removing dead vegetation like twigs and leaves, from the ground, roof and gutters — that are not under debate.
However, other new measures introduced by the state have generated controversy, especially in Los Angeles. The disputes have mainly centered around what to do about trees and other living vegetation, like shrubs and grass.
The state is considering two options for trees: One would require residents to trim branches within five feet of a house’s walls and roof; the other does not. Both require keeping trees well-maintained and at least 10 feet from chimneys.
On vegetation, the state is considering options for Zone Zero ranging from banning virtually all vegetation beyond small potted plants to just maintaining the regulations already on the books, which allow nearly all healthy vegetation.
Lee’s motion instructs the Los Angeles Fire Department to create regulations in line with the most lenient options that allow healthy vegetation and do not require the removal of tree limbs within five feet of a house. It is unclear whether LAFD will complete the process before the Board of Forestry considers finalized statewide regulations, which it expects to do midyear.
The motion follows a pointed report from LAFD and the city’s Community Forest Advisory Committee that argued the Board of Forestry’s draft regulations stepped beyond the intentions of the 2020 law creating Zone Zero, would undermine the city’s biodiversity goals and could result in the loss of up to 18% of the urban tree canopy in some neighborhoods.
The board has not decided which approach it will adopt statewide, but fire safety advocates worry that the lenient options championed by L.A. do little to protect vulnerable homes from wildfire.
Recent studies into fire mechanics have generally found that the intense heat from wildfire can quickly dry out these plants, making them susceptible to ignition from embers, flames and radiant heat. And anything next to a house that can burn risks taking the house with it.
Another recent study that looked at five major wildfires in California from the last decade, not including the 2025 Eaton and Palisades fires, found that 20% of homes with significant vegetation in Zone Zero survived, compared to 37% of homes that had cleared the vegetation.
