The black hole at the center of our galaxy is emitting near-constant, random light. The European Space Agency has approved astronaut candidate John McFall, making McFall the first physically disabled candidate to be cleared to fly. The risk of asteroid 2024 YR4 hitting Earth rose to more than 3 percent and then dipped down to 1.5 percent with new data—our February 12 episode explained why this risk has been changing.

It’s fairly strange that humans, unlike many other mammals, don’t have hair all over. Our lack of body hair and wide geographic distribution led to the variation of sun-protective melanin in our skin. For the hair that remains, why did some groups develop curls while others did not? Biological anthropologist Tina Lasisi takes host Rachel Feltman through her work on understanding the roots of hair types. Plus, they discuss what we might learn from “chemo curls” and how developmental shifts change the extent and texture of hair during puberty.

Scientists now agree that COVID spreads via airborne transmission. But during the early days of the disease, public health officials suggested that it mainly did so via close contact. The subsequent back-and-forth over how COVID spread brought science journalist Carl Zimmer into the world of aerobiology. In his new book Air-Borne: The Hidden History of the Life We Breathe, Zimmer examines the unseen life in the air around us. He joins host Rachel Feltman to look back at the history of the field, from ancient Greek “miasmas” to Louis Pasteur’s unorthodox experiments to biological warfare.

The European Space Agency recently announced that the near-Earth asteroid 2024 YR4 has a 2 percent chance of hitting our planet in 2032. The probability of impact is difficult to predict exactly and will be clearer in 2028, when 2024 YR4 will whiz by us. But if the asteroid really is on a collision course with Earth, what can we do about it? Senior space and physics editor Lee Billings joins host Rachel Feltman to unpack this headline-making story.

A subtype of H5N1 bird flu that has been found in cattle for the first time suggests that the virus jumped from birds to the animals twice. A headline-making study estimates that we have a spoon’s worth of microplastics in our brain. Streams of rock from a cosmic impact created the moon’s two deep canyons, Vallis Schrödinger and Vallis Planck. A large study shows that people feel their best in the morning and their worst at midnight. Bonobos can tell when humans don’t know something—and try to help us.

The first few weeks of the Trump administration have been marked by chaos and confusion for the nation’s health and science agencies. A funding freeze broadly targeting language around diversity, equity and inclusion has agencies evaluating research and initiatives. A hold on public communications from health agencies is affecting public health reporting to people in the U.S.—and to the World Health Organization. Entire websites have gone dark as agencies have tried to comply, though archivists are preventing critical datasets from disappearing. Max Kozlov, a Nature reporter who covers biomedical science, joins host Rachel Feltman to walk through what the next four years might hold for research and researchers in the U.S. Overall, the orders have caused uncertainty for scientists in the nation, and associate health editor Lauren Young discusses the frustration and fear she’s hearing from them.

It’s easy to be cynical about the state of the world—even when you’re a researcher who studies empathy and kindness. Stanford University psychologist Jamil Zaki turned his own negativity into his new book Hope for Cynics: The Surprising Science of Human Goodness. The book busts common myths about cynicism and explores what it could be doing to our body and brain. Zaki reflects on the imperfections of cynicism and hope and presents a third option: hopeful skepticism.

Norovirus cases are up this year, with 91 reported outbreaks nationwide. Human metapneumovirus (HMPV) cases are up in China and India. There has also been an increase in the U.S., but HMPV is currently a cause for concern in the nation, where its relative commonality gives many people some immunity. Louisiana has reported the first U.S. death from H5N1 avian influenza. Experts say the risk of bird flu to most people is low, though several factors can cause severe disease. Medical debts are set to be removed from U.S. credit reports, which could raise credit scores by an average of 20 points for the 15 million Americans who will be affected. 

Wildfires raged in the Los Angeles area last week, caused in part by a hot, dry winter and the speeds of the Santa Ana winds. Those winds made it difficult to fight the Palisades and Eaton Fires. As of last Thursday evening, firefighters were continuing to get a handle on these fires.

Low iron levels can cause fatigue and impact mental health, but doctors often miss cases of iron deficiency and anemia. Pediatric hematologist Angela Weyand, a clinical associate professor at the University of Michigan Medical School in Ann Arbor, points to one population that could be at a higher risk—young women with heavy menstrual bleeding. In one study from a national database, nearly 40 percent of otherwise healthy adolescent women were iron-deficient, and 6 percent were additionally anemic. Awareness and self-advocacy could help people receive accessible and inexpensive treatments for low iron levels.

Writings and records are how we understand long-gone civilizations without being able to interact with ancient peoples. A recent opinion paper suggested we could feed chatbots writings from the past to simulate ancient participants for social psychology studies. Similar survey experiments with modern participant data closely matched the outcomes of the real people they were based on. We speak with the opinion paper’s co-author Michael Varnum, an associate professor at Arizona State University, about what the limits of this spooky proposal are and what the ghosts of cultures past could teach us today.

Disparities in health are not indicated by adverse outcomes alone. Adriana Corredor-Waldron, an assistant professor of economics at NC State University, sought to understand why Black infants are more likely to be delivered by C-section than white infants. A working paper she co-authored found that the elevated number of low-risk Black pregnant people who were given C-section surgeries in New Jersey from 2008 to 2017 was likely caused by physician discretion. Corredor-Waldron explains why unnecessary C-sections can be risky and what medical education and financial incentives could do to close the gap.

SHOWNOTES:

Have you ever felt judged at the doctor’s office, even before you said a word? Unfortunately, that’s not uncommon, and it’s often not intentional. Like everyone, doctors have unconscious biases that can affect how they treat patients, which can pose real risks to health outcomes. In this episode, host Rachel Feltman is joined by Cristina Gonzalez, a physician and professor of medicine and population health at NYU Grossman School of Medicine, to discuss how these biases form and what can be done to address them.

The Food and Drug Administration has granted priority review to suzetrigine, a novel painkiller. It’s part of a new class of medications that could provide relief to those with chronic pain. The drugs target sodium channels on nerve cells, stopping pain signaling at the periphery. Journalist Marla Broadfoot explains the biology of aches and pains and the reasons it is so challenging to develop well-tolerated medications for pain.

Polycystic ovary syndrome (PCOS) affects up to five million people in the U.S., yet it remains poorly understood. Many people with PCOS go undiagnosed while experiencing symptoms such as irregular periods, changes in hair and body shape, acne and infertility. Even after a diagnosis, they’re often told to lose weight to manage symptoms—advice that some researchers now say can be harmful. 

A recent study found that people with PCOS are more likely to have eating disorders, regardless of their body mass index. Laura Cooney, an associate professor at the University of Wisconsin School of Medicine and Public Health, co-authored the study. She joins host Rachel Feltman to discuss why the focus on weight loss for PCOS treatment needs to be reconsidered.

As people live longer and family sizes shrink, fewer relatives are available to share the burden of caregiving for aging loved ones. The second episode of our two-part miniseries on caregiving explores what this means for the family members who take on this critical role. How do they provide the best care while also maintaining their own well-being? To hear firsthand how caregivers are navigating this challenge, Lauren Young and Tanya Lewis, Scientific American’s respective associate and senior editors of health and medicine, visited a support center in Queens, N.Y. Young shares some of the stories they gathered from the community there.

Discrimination may be speeding up the aging process for people of color and other minoritized groups. Research is revealing that structural and interpersonal racism could be key factors in why these communities often age faster and face age-related diseases sooner. Alexis Reeves, a postdoctoral researcher at Stanford University, studies how racism affects aging, with a focus on early menopause. In a conversation with Science Quickly host Rachel Feltman, Reeves discusses how traditional research methods might be overlooking these critical disparities.

The American Cancer Society published a study suggesting that for 8 or 34 cancers tracked, case rates are rising from one generation to the next. While headlines often point to sedentary lifestyles and higher weights as a possible cause, some experts say that these factors alone cannot explain the spike. In more hopeful oncology news, there’s a new blood test for colorectal cancer–though it doesn’t replace the importance of colonoscopies.

It’s a scorching summer, with record-breaking temperatures last Monday. Rain really is harder to predict, and greenhouse gasses are probably to blame. Polio is circulating in Gaza’s wastewater and could spread as conflict leads to crowding, poor sanitation and missing routine vaccinations. Plus, we discuss a shocking price for a promising HIV vaccine, cocaine sharks and komodo dragons with iron-tipped teeth.

Fish trapping is an ancient practice, reaching across the globe from at least as far back as 11,000 years ago. It takes advantage of coastal tides and human-made chambers to catch and release fish. The simple but ingenious ancient fishing structures are built on two intertwining principles: the ocean can provide for us if we properly care for it.

Archaeologists are mapping the possible locations of ancient traps. And on Penghu, a group of islands off of Taiwan, people are reviving the traditional tidal weirs, hoping to promote sustainable fishing and attract ecotourism. 

Stay tuned for more from science journalist Kata Karáth in part two of our three-part Fascination series on unusual archaeology.

Meditation is mostly mainstream, with many people using mindfulness to manage stress. But dedicated practitioners of advanced meditation move beyond mindfulness into a state where consciousness “entirely falls away.” That’s according to today’s guest: Matthew Sacchet, an associate professor and director of the Meditation Research Program at Harvard Medical School and Massachusetts General Hospital. Sacchet tells host Rachel Feltman about his journey from youthful meditator to neuroscience researcher. Plus, they discuss what meditation and psychedelic experiences are unlocking for consciousness researchers.

We’re looking at our reporting—from 100 years ago. In 1924 Scientific American’s pages were bemoaning traffic, waste management and pests. They were also praising the by-products of coal tar and those substances’ use in household items. While the record is clear on the toxicity of fossil fuels to our environment and our health, demand for fossil-fuel-based “petrochemical” products such as plastic is only increasing. Host Rachel Feltman advises on how to avoid petrochemicals in our everyday products. Plus, we take a lighthearted look at a telepathy study also featured in one of our 1924 issues.

Microplastics are everywhere—and we mean everywhere. These pesky plastic pollutants have been found in penis tissue, testicles, breast milk and blood. They’ve turned up in Antarctic snow, in the clouds above Mount Fuji, inside deep-sea creatures and near the top of Mount Everest. In Paris Olympic ambitions for the Seine’s are being complicated by bacteria. Far above Earth, the Starliner spacecraft faced a rocky road to the International Space Station (ISS). Starliner’s return to Earth is being delayed as Boeing and NASA officials take a look at the leaks and thruster failures that occurred during its journey to the ISS.

All aboard the Nathaniel B. Palmer, a research vessel making its way through the waters of West Antarctica. Journalist Sofia Moutinho is joining a team of chemists trying to find out how glacial melting is changing ocean chemistry—and what those changes might mean for the global climate.

The researchers want to know whether a negative feedback loop could take shape in Antarctica’s seas. Carbon dioxide contributes to the rise in warming that is melting the glaciers. As glacial melting releases iron, phytoplankton feast. Phytoplankton in turn remove carbon from the air, potentially causing a cooling effect.

Stay tuned for next Friday’s episode, where Moutinho will embark on a hunt for sea ice and hear about the researchers’ special encounter with Adélie penguins.

Portugal is one of the most vulnerable countries in Europe to climate change. Straddling the Mediterranean and eastern Atlantic regions, it’s part of a climate change hot spot. Some of the biggest fuels are shrubs. One study found that shrubland covers 1.6 million hectares in Portugal—about 18 percent of the nation’s land area. And those shrubs are gaining ground. That’s because, for decades, people have been moving out of rural communities such as the one Tommy Ferreira lives in. Most leave to pursue better-paying jobs in the cities or in wealthier European Union countries. Portugal has lost 30 percent of its rural population since 1960. The same trend is occurring across the Mediterranean region. Abandoning these farmlands is increasing wildfire risk, according to an Organization for Economic Co-operation and Development report released last spring. When people who work the land leave it, grazing pastures and farm fields become thick with fuels. But these ancient Maronesa cattle can help solve both of these modern-day problems. It was a solution hiding in plain sight.

For the last decade, reports of UFO sightings have filled headlines and news broadcasts, and some of these have from a surprising place—the Pentagon. Former defense officials have made a number of claims about, and released videos of, strange sightings made by military pilots.

These days, the objects are officially called “UAPs”—unidentified anomalous phenomena.

But regardless of the new branding, Congress has demanded answers on them, especially after one former official this summer claimed that he believed that the U.S. possessed “nonhuman” spacecraft and possibly their “dead pilots.”

We talk to the former intelligence official and physicist, Sean Kirkpatrick, who until December headed the All-domain Anomaly Resolution Office, the Pentagon office that Congress told to find some answers to all this. He recently published an op-ed in Scientific American called  "Here's What I Learned as the U.S. Government's UFO Hunter".
