Credit: Shutterstock University of Colorado Boulder researchers made the first-ever airborne detection of Medium Chain Chlorinated Paraffins (MCCPs) in the Western Hemisphere. Sometimes, scientific research feels a lot like solving a mystery. Scientists head into the field with a clear goal and a solid hypothesis, but then the data reveals something surprising. That’s when the real detective work begins. This is exactly what happened to a team from the University of Colorado Boulder during a recent field study in rural Oklahoma. They were using a state-of-the-art instrument to track how tiny particles form and grow in the air. But instead of just collecting expected data, they uncovered something completely new: the first-ever airborne detection of Medium Chain Chlorinated Paraffins (MCCPs), a kind of toxic organic pollutant, in the Western Hemisphere. The teams findings were published in ACS Environmental Au. “It’s very exciting as a scientist to find something unexpected like this that we weren’t looking for,” said Daniel Katz, CU Boulder chemistry PhD student and lead author of the study. “We’re starting to learn more about this toxic, organic pollutant that we know is out there, and which we need to understand better.” MCCPs are currently under consideration for regulation by the Stockholm Convention, a global treaty to protect human health from long-standing and widespread chemicals. While the toxic pollutants have been measured in Antarctica and Asia, researchers haven’t been sure how to document them in the Western Hemisphere’s atmosphere until now. From Wastewater to Farmlands MCCPs are used in fluids for metal working and in the construction of PVC and textiles. They are often found in wastewater and as a result, can end up in biosolid fertilizer, also called sewage sludge, which is created when liquid is removed from wastewater in a treatment plant. In Oklahoma, researchers suspect the MCCPs they identified came from biosolid fertilizer in the fields near where they set up their instrument. “When sewage sludges are spread across the fields, those toxic compounds could be released into the air,” Katz said. “We can’t show directly that that’s happening, but we think it’s a reasonable way that they could be winding up in the air. Sewage sludge fertilizers have been shown to release similar compounds.” MCCPs little cousins, Short Chain Chlorinated Paraffins (SCCPs), are currently regulated by the Stockholm Convention, and since 2009, by the EPA here in the United States. Regulation came after studies found the toxic pollutants, which travel far and last a long time in the atmosphere, were harmful to human health. But researchers hypothesize that the regulation of SCCPs may have increased MCCPs in the environment. “We always have these unintended consequences of regulation, where you regulate something, and then there’s still a need for the products that those were in,” said Ellie Browne, CU Boulder chemistry professor, CIRES Fellow, and co-author of the study. “So they get replaced by something.” Measurement of aerosols led to a new and surprising discovery Using a nitrate chemical ionization mass spectrometer, which allows scientists to identify chemical compounds in the air, the team measured air at the agricultural site 24 hours a day for one month. As Katz cataloged the data, he documented the different isotopic patterns in the compounds. The compounds measured by the team had distinct patterns, and he noticed new patterns that he immediately identified as different from the known chemical compounds. With some additional research, he identified them as chlorinated paraffins found in MCCPs. Katz says the makeup of MCCPs are similar to PFAS, long-lasting toxic chemicals that break down slowly over time. Known as “forever chemicals,” their presence in soils recently led the Oklahoma Senate to ban biosolid fertilizer. Now that researchers know how to measure MCCPs, the next step might be to measure the pollutants at different times throughout the year to understand how levels change each season. Many unknowns surrounding MCCPs remain, and there’s much more to learn about their environmental impacts. “We identified them, but we still don’t know exactly what they do when they are in the atmosphere, and they need to be investigated further,” Katz said. “I think it’s important that we continue to have governmental agencies that are capable of evaluating the science and regulating these chemicals as necessary for public health and safety.” Reference: “Real-Time Measurements of Gas-Phase Medium-Chain Chlorinated Paraffins Reveal Daily Changes in Gas-Particle Partitioning Controlled by Ambient Temperature” by Daniel John Katz, Bri Dobson, Mitchell Alton, Harald Stark, Douglas R.

Subscribe here.Welcome to The Logoff: President Donald Trump and Elon Musk’s increasingly nasty public split is dominating headlines today, and you can read all about it here. But it also means that another change Trump made this week is flying under the radar — one with consequences for millions of people around the world.What just happened? On Wednesday evening, the Trump administration announced a total ban on entry to the US for citizens of 12 countries, resurrecting a key first-term policy. The ban also includes partial restrictions on seven other countries and is set to take effect this coming Monday, June 9.Which countries does the ban impact? Immigrants, students, and tourists will all be affected. Citizens of Afghanistan, Myanmar, Chad, Republic of the Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, and Yemen are subject to a total ban, while all immigrant visas and many classes of non-immigrant visa for citizens of Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan, and Venezuela are covered by the partial restrictions.What’s the context? This new ban isn’t a surprise — a “Muslim ban,” which was eventually upheld by the Supreme Court after multiple iterations, was a flagship policy in the first Trump administration, and the second Trump administration has previously signaled its intent to bring back some version of the policy. In March, it was reported that the administration was considering various restrictions on at least 43 different countries. What’s different this time? The new ban covers more countries and cites a wider range of justifications. In addition to national security concerns, the ban also alleges “significant risks” of visa overstays from some of the impacted countries. It comes as the administration steps up an ever-more-aggressive campaign of deportation and anti-immigration policies.

Data broker LexisNexis Risk Solutions (LNRS) has just disclosed a data breach that occurred at the end of last year, and while it doesn't affect as many individuals as other recent high profile incidents—such as the DISA hack that included 3.3 million people's information—it underscores the ever-present concerns with companies collecting (and profiting off of) user data. As TechCrunch reports, LexisNexis Risk Solutions uses consumers' personal and financial information to help corporations conduct risk assessments on prospective customers and detect fraudulent transactions. For example, LexisNexis sold data on vehicle driving habits collected by car manufacturers to insurance companies to set premiums, while law enforcement agencies pull data from LexisNexis about suspects. (LexisNexis Risk Solutions is a subsidiary of the same corporation that owns data analytics and research firm LexisNexis.)The LexisNexis hack compromised data collected on 364,333 individuals, and there's a potential class action lawsuit brewing over the incident. Here's what you need to know. What happened with LexisNexis?According to the company's filing with the Maine attorney general's office, a data breach took place on December 25, 2024 but wasn't discovered until May 14, 2025. A third-party platform used by LexisNexis was hacked, compromising information that may include the following: NamePhone numberMailing addressEmail addressSocial Security numberDriver's license numberDate of birthIn a letter to affected individuals, LexisNexis states that no financial or credit card information was included in the breach, nor has any data been obviously misused (so far). Few additional details about the incident have been disclosed, other than that none of the company's own networks or systems were hacked. What consumers need to doLexisNexis sent a notice dated May 24 to consumers whose data may have been compromised, so if you receive a letter from LexisNexis Risk Solutions, don't throw it out. The company is offering 24 months of identity protection and credit monitoring services through Experian IdentityWorks, and you must enroll online by August 31, 2025 using the activation code provided in your notice.

May 30, 20256 min readInside the Lifesaving Power of Doppler Weather RadarDoppler radar is one of the most revolutionary and lifesaving tools of modern meteorology, which has experts worried about outages because of recent staffing cuts and conspiracy theoriesBy Andrea Thompson edited by Dean Visser Mfotophile/Getty ImagesOutside every National Weather Service (NWS) office around the U.S. stands what looks like an enormous white soccer ball, perched atop metal scaffolding several stories high. These somewhat plain spheres look as ho-hum as a town water tower, but tucked inside each is one of modern meteorology’s most revolutionary and lifesaving tools: Doppler radar.The national network of 160 high-resolution radars, installed in 1988 and updated in 2012, sends out microwave pulses that bounce off raindrops or other precipitation to help forecasters see what is falling and how much—providing crucial early information about events ranging from flash floods to blizzards. And the network is especially irreplaceable when it comes to spotting tornadoes; it has substantially lengthened warning times and reduced deaths. Doppler radar has “really revolutionized how we’ve been able to issue warnings,” says Ryan Hanrahan, chief meteorologist of the NBC Connecticut StormTracker team.But now meteorologists and emergency managers are increasingly worried about what might happen if any of these radars go offline, whether because of cuts to the NWS made by the Trump administration or threats from groups that espouse conspiracy theories about the radars being used to control the weather. “Losing radar capabilities would “take us back in time by four decades,” says Jana Houser, a tornado researcher at the Ohio State University. If they go down, “there’s no way we’re going to be effective at storm warnings.”On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.How Doppler radars workThe NWS installations form a network called the Next Generation Weather Radar, or NEXRAD. Inside each giant white sphere is a device that looks like a larger version of a home satellite TV dish, with a transmitter that emits pulses in the microwave region of the electromagnetic spectrum. Those pulses bounce off raindrops, snowflakes, hailstones—what meteorologists collectively call hydrometeors—and back to the dish antenna. (The pulses also sometimes bounce off bats, birds and even moving trains, which yield characteristic radar patterns that experts can usually identify.)Amanda MontañezThe power of the returning signals lets experts create a picture of size, shape and intensity of any precipitation—and this is what you see on a phone app’s radar map or a TV broadcast.But NEXRAD can do much, much more than show how hard it’s raining. Within its sphere, each unit rotates and scans up and down through the sky, helping forecasters see what is happening at multiple levels of a storm system. These vertical profiles can show, for example, whether a tornado is forming or a storm is creating a downburst—a rapid downward blast of wind. “Doppler radar basically allows us to see in the clouds,” Hanrahan says.And then there’s the “Doppler” part itself. The name refers to a phenomenon that’s familiar to many, thanks to the electromagnetic waves’ acoustic counterpart. We’ve all experienced this, often most obviously when we hear an emergency vehicle siren pass nearby: the pitch increases as the car gets closer and decreases as it moves away. Similarly, the returning radar bounce from a rain droplet or piece of tornadic debris that is moving toward the emitter will have a shorter wavelength than the pulse that was sent out, and the signal from an object moving away from the radar will have a longer wavelength. This allows the radar to efficiently distinguish the tight circulation of a tornado.These two images show how dual-polarization helps NWS forecasters detect a tornado that is producing damage. The left image shows how the Doppler radar can detect rotation. Between the two yellow arrows, the red color indicates outbound wind, while the green color indicate inbound wind, relative to the location of the radar. The right image shows how dual-polarization information helps detect debris picked up by the tornado.NOAAThe nation’s radar system was upgraded in 2012 to include what is called dual polarization. This means the signal has both vertically and horizontally oriented wavelengths, providing information about precipitation in more than one dimension. “A drizzle droplet is almost perfectly spherical, so it returns the same amount of power in the horizontal and in the vertical,” Hanrahan says, whereas giant drops look almost like “hamburger buns” and so send back more power in the horizontal than the vertical.Are Doppler radars dangerous? Can they affect the weather?Doppler radars do not pose any danger to people, wildlife or structures—and they cannot affect the weather.Along the electromagnetic spectrum, it is the portions with shorter wavelengths such as gamma rays and ultraviolet radiation that can readily damage the human body—because their wavelengths are the right size to interact with and damage DNA or our cells. Doppler radars emit pulses in wavelengths about the size of a baseball.Amanda MontañezBeing hit by extremely concentrated microwave radiation could be harmful; this is why microwave ovens have mesh screens that keep the rays from escaping. Similarly, you wouldn’t want to stand directly in front of a radar microwave beam. Military radar technicians found this out years ago when working on radars under operation, University of California, Los Angeles, climate scientist Daniel Swain said during one of his regular YouTube talks. They “had experiences like the candy bar in their pocket instantly melting and then feeling their skin getting really hot,” he said.Similar to how a microwave oven works, when the microwave signal from a radar hits a hydrometeor, the water molecules vibrate and so generate heat because of friction and reradiate some of the received energy, says Cynthia Fay, who serves as a focal point for the National Weather Service’s Radar Operations Center. But “microwave radiation is really not very powerful, and the whole point is that if you stand more than a couple dozen feet away from the dome it's not even really going to affect your body, let alone the global atmosphere,” Swain adds.At the radar’s antenna, the average power is about 23.5 megawatts (MW) of energy, Fay says. (A weak or moderate thunderstorm may generate about 18 MW in about an hour.) But the energy from the radar signal dissipates very rapidly with distance: at just one kilometer from the radar, the power is 0.0000019 MW, and at the radar’s maximum range of 460 kilometers, it is 8.8 x 10–12 MW, Fay says. “Once you’re miles away, it’s just really not a dangerous amount” of energy, Swain said in his video.A supercell thunderstorm that produced an F4 tornado near Meriden, KS, in May 1960, as seen from the WSR-3 radar in Topeka (left). A supercell thunderstorm that produced an EF5 tornado in Moore, OK, in May 2013, as seen from a modern Doppler weather radar near Oklahoma City (right).NOAAAnd Doppler radars spend most of their time listening for returns. According to the NWS, for every hour of operation, a radar may spend as little as seven seconds sending out pulses.The idea that Doppler radar can control or affect the weather is “a long-standing conspiracy [theory] that has existed really for decades but has kind of accelerated in recent years,” Swain said in his video. It has resurfaced recently with threats to the National Oceanic and Atmospheric Administration radar system from an antigovernment militia group, as first reported by CNN. The Washington Post reported that the group’s founder said that its members were carrying out “attack simulations” on sites in order to later destroy the radars,—which the group believes are “weather weapons,” according to an internal NOAA e-mail. NOAA has advised radar technicians at the NWS’s offices to exercise caution and work in teams when going out to service radars—and to notify local law enforcement of any suspicious activity.“NOAA is aware of recent threats against NEXRAD weather radar sites and is working with local and other authorities in monitoring the situation closely,” wrote a NWS spokesperson in response to a request for comment from Scientific American.What happens if weather radars go offline?NOAA’s radars have been on duty for 24 hours a day, seven days a week and 365 days a year since 1988 (with brief downtimes for maintenance and upgrades). “It’s amazing what workhorses these radars have been,” Hanrahan says.The image on the left shows a reflectivity radar image of a supercell thunderstorm that produced several tornadoes on April 19, 2023, near Oklahoma City, OK. The hook shape present often indicates rotation within the storm. The image on the right show velocity information that corresponds to the reflectivity image. Very strong inbound winds (green colors) are next to very strong outbound winds (bright red/yellow colors). This very strong inbound/outbound “couplet” indicates the very strong rotation of a tornado.NOAABut they do require that periodic maintenance because of all the large moving parts needed to operate them. And with Trump administration cuts to NOAA staffing and freezes on some spending, “we just got rid of a lot of the radar maintenance technicians, and we got rid of the budget to repair a lot of these sites,” Swain said in his video. “Most of these are functioning fine right now. The question is: What happens once they go down, once they need a repair?”It is this outage possibility that most worries weather experts, particularly if the breakdowns occur during any kind of severe weather. “Radars are key instruments in issuing tornado warnings,” the Ohio State University’s Houser says. “If a radar goes down, we’re basically down as to what the larger picture is.”And for much of the country—particularly in the West—there is little to no overlap in the areas that each radar covers, meaning other sites would not be able to step in if a neighboring radar is out. Hanrahan says the information provided by the radars is irreplaceable, and the 2012 upgrades mean “we don’t even need to have eyes on a tornado now to know that it’s happening. It’s something that I think we take for granted now.”

Women have been an important part of the armed services since the beginning, with icons like Harriet Tubman participating in the Civil War. While being female in a traditionally male-dominated space hasn't always been easy, these women have still served their countries.In 2023, the US Department of Defense reported that the percentage of women serving in active and reserve capacities was growing. In 2022, 17.5% of active-duty roles and 21.6% of the National Guard and reserves were women, up slightly from the year before, it reported, citing the 2022 Demographics Profile of the Military Community.On Memorial Day this year, here are 12 famous women who have served in the military around the world, including Bea Arthur, Queen Elizabeth, and more. Harriet Tubman was a military leader and Union spy during the Civil War. Harriet Tubman. MPI/Getty Images Most know Harriet Tubman for her groundbreaking work with the Underground Railroad and, later, as an abolitionist, but as National Geographic reported, Tubman was also an integral part of the Civil War.In 1863, Tubman and Colonel James Montgomery led a group of soldiers in freeing slaves from plantations in South Carolina, making Tubman the first woman in US history to lead a military expedition, according to National Geographic.Her work continued as a spy and recruiter for the Union Army. This operation was so covert that only President Lincoln knew about it.Tubman received compensation for her military contributions decades later, in 1899. Thomas B. Allen, the author of "Harriet Tubman, Secret Agent," called Tubman "one of the great heroines of the Civil War." Queen Elizabeth was a military truck driver during World War II. Queen Elizabeth outside a first aid truck during World War II. Keystone/Getty Images Queen Elizabeth was only 18 years old when she begged her father, King George VI, to take part in helping out during World War II. She joined the Women's Auxiliary Territorial Service in England that same year and was known as "Second Subaltern Elizabeth Windsor," according to the National Archives.While serving, the young queen drove military trucks and trained as a mechanic, making her, to this day, the only female member of the Royal Family to enter the armed forces.  NASA's Eileen Collins was one of the first female pilots in the Air Force and in space. Eileen Collins. NASA Eileen Collins broke several barriers during her career: Not only was she NASA's first female shuttle commander, but at 23, she became the Air Force's first female flight instructor, according to the agency.She joined the Air Force in 1978, becoming one of the first four women to go through pilot training at Vance Air Force Base in Enid, Oklahoma. She wrote in Time, "The Air Force was testing whether women could succeed as military pilots. We obviously were living in a fishbowl — everyone knew who we were, our personal business, our test scores and our flight performance. My philosophy was to be the best pilot I could be."Her military training directly led her to test-pilot school, where she "knew" she would go on to be the first female space shuttle pilot — and succeeded in doing so.   "Golden Girl" Bea Arthur was one of the first members of the Marine Corps Women's Reserve.

Lennox McLendon/AP Photo Before she was Dorothy Zbornak on "The Golden Girls," Emmy Award-winning actor Bea Arthur was a Marine.As reported by The Daily Beast, Arthur enlisted in the Women's Reserve when she was 21 years old. She first served as a typist and truck driver. She worked her way up to staff sergeant and was honorably discharged in 1945. Official documents show that Arthur's supervisors thought she was "argumentative," which is not a far cry from the feisty persona she became known for on both "The Golden Girls" and "Maude." "Stranger Things" actor Jennifer Marshall served in the US Navy for five years. Jennifer Marshall as Susan Hargrove on "Stranger Things." Netflix Before Jennifer Marshall scored the role of Susan Hargrove on Netflix's hit show "Stranger Things," she served in the United States Navy from ages 17 to 22. According to Marshall's website, during her service, she was a forklift operator, aircraft handler, and logistics specialist. She also worked for the USS Theodore Roosevelt's Sexual Assault Victim Intervention (SAVI) program. Marshall was awarded many honors and medals for her time in the Navy. Now, in addition to acting, she works with Pin-Ups For Vets, a nonprofit organization that aids hospitalized veterans and deployed troops. Food Network star Sunny Anderson was in the Air Force. Sunny Anderson. Jim Spellman/Getty Images Anderson, who hosts "The Kitchen," "Cooking for Real," and "Home Made in America," grew up around the military because of her parents. As an adult, she enlisted in the US Air Force as a radio broadcaster and journalist, working in Seoul, South Korea, and in San Antonio. "I knew that there were radio stations, television stations, newspapers, and magazines, for the military, by the military, and I wanted to be a part of that," Anderson told ABC News in 2013.She also wanted to train in something that would be useful when she left the military."My transition from the Air Force started before I even got in the Air Force," she said. Radio talk show host Robin Quivers was a captain in the Air Force. Robin Quivers. Walter McBride/WireImage via Getty Images Robin Quivers has co-hosted "The Howard Stern Show" for over 30 years, but before that, she served as a captain in the US Air Force.Quivers got her degree in nursing from the University of Maryland and put it to use by joining the military as a second lieutenant after college. She quickly climbed the ranks, and when she was discharged in 1978, her official title was captain, according to Biography.com.She served as a reserve in the Air Force until 1990, per military records, after which she fully pivoted to her career in radio. But Howard Stern hired her for his show in 1981, which means that Quivers — though she was "inactive" — was still technically serving while she was on the air. Actor Zulay Henao served in the US Army for three years. Zulay Henao. JB Lacroix/ Getty Images Colombian-American actor Zulay Henao has appeared on the show "Army Wives," but few know that she herself served in the US Army before becoming an actor.Henao enlisted after completing high school and, after three years of serving, went on to enroll at the New York Conservatory for Dramatic Arts.She previously spoke to the paparazzi about her time in the military, saying: "I wouldn't be doing what I'm doing, and I wouldn't have the perspective I have of the world, if it weren't for the Army." Olympic medalist Shauna Rohbock was in the National Guard. Shauna Rohbock.

Technically not yet a veteran, she's a logistics officer and member of the Army Marksmanship Unit, according to Military.com.After English's win, Defense Secretary Lloyd Austin congratulated her on Twitter, now known as X."Your country is extremely proud of you today, and I'm so glad you're representing us," he wrote.She joins an illustrious list of medal winners, both male and female, with military backgrounds. "Wonder Woman" Gal Gadot served in the Israel Defense Forces for two years. Gal Gadot. Dia Dipasupil/Getty Images After Gal Gadot was crowned Miss Israel in 2004 and before she became Wonder Woman in 2017, she served her mandatory two years in the IDF. During her assignment, she worked as a "physical fitness specialist," teaching gymnastics and calisthenics to the soldiers, PopSugar reported.Pro-Palestine groups have criticized her service, as well as her support of the Israeli military and cause in social media posts."I think much of it comes from ignorance and people not understanding what most people do in the army in Israel or what I did in the army during my service in the military," she told The Jakarta Post in May 2021. She added, "Being an Israeli and going to the army is an integral thing. It's something you have to do. It's mandatory." Ruth Westheimer, better known as the sex therapist Dr. Ruth, trained as a sniper in the IDF. Dr. Ruth. Donna Svennevik/Walt Disney Television/Getty Images Dr. Ruth was a Holocaust survivor, and after World War II ended, she moved as a teenager to what would become Israel. During her time there, she trained as a sniper due to her small size.She told The New Yorker in 2013, "I have no idea what the experience would be if I had to show it. But I was a very good sniper."Melina Glusac contributed to an earlier version of this story.
