Here's how to find the correct one As a teenager, I loved reading my horoscope in gossip magazines. But even then my friends and I knew it was nonsense. When I shared my opinion on astrology and horoscopes, she simply replied, “Typical Taurus.” Astrology is currently experiencing a remarkable renaissance—especially on social media, where posts about “Geminis,” “Leos” and “Virgos rising” are everywhere. The trend may partly reflect how deeply people want to identify with personality types and, in the process, gain some insights into an uncertain future. And perhaps surprisingly, many astrology posts come from people who consider themselves to be scientifically inclined. Today modern science and astrology stand in stark contrast to each other. Yet the origin of horoscopes is not entirely unscientific. It's actually a story that begins with careful observation of the cosmos and the creation of a calendar system thousands of years ago in the Middle East.

The zodiac signs, considered the foundation of modern astrology by many people, are based on 12 constellations: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpius, Sagittarius, Capricorn, Aquarius and Pisces. Thanks to Mesopotamia's geographic location, it has historically had highly consistent weather patterns. And because certain constellations are visible in the night sky at different times of the year, people may have believed there was a connection between the stars and these seasons. This idea isn't such a stretch: after all, scientists today recognize that the sun and moon do indeed influence earthly events such as the weather and the tides. But distant stars, as we'll discuss later, are a different story. In doing so, they developed the first known astronomical coordinate system. In retrospect, it doesn't seem so far-fetched that people in antiquity or the Middle Ages believed that constellations influenced us. We now know much more about astronomy, physics and celestial mechanics. For example, scientists have long understood that constellations are composed of objects that are sometimes very far apart and have no connection to one another, except that they appear close together from our vantage point here on Earth. Furthermore, their distance from Earth is so great that they—unlike the moon or the sun—cannot actually influence us or our planet. Stars are gigantic fusion reactors light-years away that do not shape our personalities or life events. But if you find yourself talking to someone who's hooked on horoscopes, here are three scientifically grounded points you might raise: Or rather it was probably intentionally left off the list because it didn't fit into the Babylonians' system of 12 months. Not every zodiac sign corresponds to a month. For example, the sun only passes through the constellation Scorpius's boundaries for six to seven days, while it takes 44 to 45 days to travel through the much larger Virgo constellation's boundaries. This movement shifts which constellations appear in the ecliptic at what time of year. A scientifically correct zodiac system does exist. But don't worry, Scientific American is not going to be printing horoscopes based on the corrected zodiac—except, perhaps, as a joke.

Losing an hour of sleep to daylight saving time is not good for you, but there are ways you can help yourself bounce back When it comes to health, daylight saving time, frankly, sucks. It's not just that we lose an hour of sleep (which is, in itself, harmful), it's that every day spent in daylight saving time takes a toll on our body, says Emily Manoogian, a senior staff scientist at the Salk Institute for Biological Studies, who studies the body's biological clocks. “It's not the one-hour shift that makes everyone feel bad. It's this chronic disruption that makes us worse versions of ourselves.” But that's just not possible for some, and others might forget about the forthcoming clock change. Others still can be more profoundly affected by the lost hour of sleep, much in the same way that some people are less able to cope with jet lag. If you're enjoying this article, consider supporting our award-winning journalism by subscribing.

Jet lag is a good way to think about daylight saving time, says Manoogian, who is also a member of the Center for Circadian Biology at the University of California, San Diego, and public outreach chair at the Society for Research on Biological Rhythms. The circadian system refers to the body's suite of clocks—every cell with DNA has a clock, and each of these clocks feeds back into one another. Our brain acts as a kind of Time Lord that uses light and other sensory cues to coordinate our behavior, such as when we eat and sleep, and that regulates the timing of all the clocks. Take eating breakfast: For days after daylight saving comes into effect, your glucose regulation may be compromised because your body's clocks sense that you are fasting and still asleep when you are, in fact, awake. If you eat first thing, your blood sugar levels could rise higher than usual. Foggy thinking and poor food choices are also common reactions to the time change, she says. For folks who find themselves feeling a little out of it in the days after daylight saving, making sure that you are getting outside, preferably into the sunshine, exercising and going to bed earlier for a week or so can help combat some of these ill effects. Sleep in if you can, she says, and don't force yourself to do anything too strenuous in the mornings for a few days. Putting our body's clocks out of sync can be deadly, Manoogian says. For people who are already at higher risk, “that misalignment and forcing your body to do something before it's ready can be enough to tip it over,” she says. The lack of sleep can also lead to more car accidents. Food plays an important role in this process, she says: “This can also be a good time to reassess when you should be eating because a lot of us eat too early or too late.” Giving yourself an hour after you wake up before you eat and a couple of hours to digest before bedtime can help regulate your circadian rhythms. Of course, people who need to stick to a schedule, particularly school-age children, don't have the luxury of taking their time in the morning. Unfortunately for all of us forced to go through daylight saving time, there are no documented health benefits from the time change, Manoogian says. “The whole time we're on it, we're hurting ourselves just a little bit, and it affects some groups more than others,” she says. Originally from Scotland, she moved to New York City in 2012. Her work has appeared in National Geographic, Slate, Inc. Magazine, Nautilus, Semafor, and elsewhere.

A researcher from the University of Houston is helping identify vulnerable bridges across the planet and offering a new way to address potential failures before they become catastrophic. In a global analysis of 744 bridges published in Nature Communications, Pietro Milillo and collaborators from several international institutions evaluated the condition of bridges around the world. The team also proposed a strategy that could transform how infrastructure is monitored worldwide by using satellites to track bridge stability and detect warning signs early. This technology captures high resolution images frequently and covers large areas of the planet, while also providing access to extensive historical data. "By integrating satellite data into risk frameworks, we can significantly lower the number of bridges classified as high-risk, especially in regions where installing traditional sensors is too costly." They relied on a remote sensing method known as Multi-Temporal Interferometric Synthetic Aperture Radar (MT-InSAR). This technique can complement traditional inspections by identifying extremely small shifts in structures. It can also reveal unusual patterns across wide areas that might signal emerging structural issues. Visual inspections carried out in person can be costly and sometimes subjective. They are also typically performed only twice a year, which means early warning signs of deterioration may go unnoticed between inspections. However, these systems are usually installed only on newer bridges or structures already known to have issues. "Remote sensing offers a complement to SHM sensors, can reduce maintenance costs, and can support visual inspections, particularly when direct access to a structure is challenging," said Millilo. "For bridges specifically, MT-InSAR allows for more frequent deformation measurements across the entire infrastructure network, unlike traditional inspections, which typically occur only a few times per year and require personnel on the ground." Our work provides the global-scale evidence showing this is a viable and effective tool that can be deployed now." The researchers found that adding MT-InSAR data to bridge risk evaluations can improve accuracy. The technique analyzes satellite pixels known as persistent scatterers (PS), which have stable radar reflections. Using these signals reduces uncertainty and allows engineers to better prioritize which bridges require maintenance or closer inspection. Integrating these data sources into a bridge's structural vulnerability score allows engineers to receive more frequent updates than traditional inspection schedules provide.

In a study published March 5 in the Cell Press journal Cell Press Blue, researchers describe a newly identified biological process that may help explain how tau builds up. The research combined animal experiments, cell studies, and analyses of tissue from patients. "Our findings reveal a previously underappreciated, disease-relevant role for tanycytes in neurodegeneration," says corresponding author Vincent Prevot of INSERM in France. "Focusing on tanycyte health could be a way to improve tau clearance and limit disease progression." This fluid surrounds the brain and spinal cord and acts as a communication network that helps maintain the body's internal balance. "Surprisingly, we were able to show in rodent and cellular models not only that tanycytes were indeed involved in clearing tau but also that tanycytes in the brains of human Alzheimer's patients were fragmented and had changes in gene expression related to this shuttle function," Prevot says. One obstacle is the lack of reliable animal models that fully replicate Alzheimer's disease. "Our findings provide the first evidence for structural and functional alterations in these little-known but key brain cells in human disease," says Prevot.

For many years, nuclear physicists believed that "Islands of Inversion" were found mainly in isotopes packed with extra neutrons. In these cases, the well known magic numbers vanish, round nuclear shapes break down, and the nucleus can shift into a highly distorted form. Until now, every known example occurred in very unstable, neutron rich nuclei. All of these lie far from the stable elements commonly found in nature. A new study by an international research team has uncovered something unexpected. Scientists from the Center for Exotic Nuclear Studies, Institute for Basic Science (IBS), University of Padova, Michigan State University, University of Strasbourg, and several other institutions have identified an Island of Inversion in a place no one anticipated. In this region, the number of protons and neutrons is equal. Both lie along the N = Z line, which is especially important in nuclear physics. To generate the required beam, scientists accelerated Mo-92 ions and fired them at a beryllium target, producing fast moving Mo-86 nuclei. During this step, some nuclei became excited, while others lost two neutrons and transformed into Mo-84. Scientists also used TRIPLEX, an instrument designed to measure extremely short lifetimes that last only trillionths of a second. Although Mo-84 and Mo-86 differ by only two neutrons, their behavior is very different. This means that many protons and neutrons move together across a major shell gap. Nuclear physicists describe this phenomenon as a "particle-hole excitation." In this process, some nucleons jump to higher energy orbitals, becoming particles, while leaving empty spaces, or holes, in lower energy orbitals. When many nucleons participate in these coordinated transitions, the nucleus becomes strongly deformed. Detailed theoretical calculations helped explain why the two isotopes behave so differently. In Mo-84, protons and neutrons undergo very large simultaneous particle hole excitations. The researchers also found that these results cannot be reproduced without accounting for three nucleon forces. Models that include only traditional two nucleon interactions fail to produce the observed structure. It exhibits more modest 4p-4h excitations and therefore remains far less deformed. Taken together, the findings show that Mo-84 sits inside a newly identified "Island of Inversion," while Mo-86 lies outside this region. The discovery challenges long standing assumptions about where these unusual nuclear regions can form and offers new insight into the fundamental forces that hold atomic nuclei together.

Roughly 15% of asteroids that pass near Earth have a smaller companion orbiting them. A research team led by the University of Maryland has now found that these systems are far more active than scientists once thought. Instead of simply orbiting one another, the two bodies can exchange rocks and dust through gentle, slow moving impacts that gradually reshape their surfaces over millions of years. The discovery comes from a close analysis of images captured by NASA's Double Asteroid Redirection Test (DART) spacecraft in 2022 just before it intentionally collided with the asteroid moon Dimorphos. In those images, the scientists noticed bright, fan shaped streaks on Dimorphos' surface. These markings provide the first direct visual proof that material can naturally travel from one asteroid to another. The results were published March 6, 2026 in The Planetary Science Journal and could help scientists better understand asteroids that might one day threaten Earth. "At first, we thought something was wrong with the camera, and then we thought it could've been something wrong with our image processing," said the paper's lead author Jessica Sunshine, a professor with joint appointments in the Department of Astronomy and Department of Geological, Environmental, and Planetary Sciences at UMD. We had the first direct proof for recent material transport in a binary asteroid system." In this phenomenon, sunlight gradually accelerates the rotation of small asteroids. Sunshine explained that this likely occurred in the Didymos system, which includes the larger asteroid Didymos and its smaller moon Dimorphos. The marks left by the so called "cosmic snowballs" on Dimorphos suggest that debris spun off Didymos and later landed on its companion. UMD astronomy research scientist Tony Farnham and former postdoctoral researcher Juan Rizos developed specialized techniques to remove shadows cast by boulders and lighting artifacts from the photos. "We ended up seeing these rays that wrapped around Dimorphos, something nobody's ever seen before," Farnham said. That made it difficult to determine whether certain features were real or simply the result of lighting conditions. "It confirmed to us that we were working with something real." Scientists had previously gathered indirect evidence suggesting that sunlight can increase the spin rate of small asteroids until surface material is ejected. The models also pinpoint where debris launched from Didymos eventually landed on Dimorphos. '19, Ph.D. '22, astronomy) determined that the debris left Didymos traveling at only 30.7 centimeters per second. That speed is slower than a typical human walking pace. "That would explain the distinctive fan-shaped marks," Sunshine said. To test their explanation, researchers led by former UMD postdoctoral associate Esteban Wright conducted laboratory experiments at UMD's Institute for Physical Science and Technology. This produced ray like patterns similar to the streaks observed on Dimorphos. Computer simulations performed at Lawrence Livermore National Laboratory reached the same conclusion. "We could see these marks on Dimorphos from that footage captured by the DART spacecraft right before the big collision, proof that there was material exchange between it and Didymos," Sunshine said. The European Space Agency's Hera mission is scheduled to reach Didymos in December 2026. Sunshine and her colleagues also expect Hera might detect new ray patterns created by boulders that were dislodged when DART struck Dimorphos. "These new details emerging from this research are crucial to our understanding of near-Earth asteroids and how they evolve," Sunshine said. "We now know that they're far more dynamic than previously believed, which will help us improve our models and our planetary defense measures." Note: Content may be edited for style and length.

People who reported using a smartphone while sitting on the toilet were more likely to have hemorrhoids than those who did not use their phones in the bathroom. Doctors and patients have long suspected that using a smartphone while sitting on the toilet might contribute to hemorrhoids, but there has been little scientific research examining this possible link. To investigate the question, Ramprasad and colleagues studied 125 adults who were undergoing screening colonoscopies. Endoscopists then examined the participants for signs of hemorrhoids. These individuals were generally younger than those who said they did not use their phones in the bathroom. After adjusting for factors that could influence hemorrhoid risk, including age, exercise habits, and fiber intake, the researchers found a clear difference. About 37 percent of people who used smartphones in the bathroom reported spending more than five minutes there during a single visit. In comparison, only 7.1 percent of non users reported staying that long. Interestingly, the study did not find a connection between straining during bowel movements and hemorrhoid risk, which differs from conclusions drawn in some earlier studies. Sitting for longer periods could increase pressure on tissues in the anal region, which may contribute to the development of hemorrhoids. The findings could help doctors offer more practical guidance to patients about bathroom habits. Future studies may build on this research by following patients over longer periods or testing strategies designed to reduce smartphone use while on the toilet. Trisha Pasricha, senior author of the study, explains: "Using a smartphone while on the toilet was linked to a 46 percent increased chance of having hemorrhoids. It's possible that how and where we use them -- such as while in the bathroom -- can have unintended consequences." She also noted that the results reinforce a simple piece of advice. "It's incredibly easy to lose track of time when we're scrolling on our smartphones -- popular apps are designed entirely for that purpose. But it's possible that constantly sitting longer on the toilet than you intended because you're distracted by your smartphone could increase your risk of hemorrhoids.

A new study from Northwestern University warns that coordinated scientific fraud is becoming increasingly common. From fabricated data to purchased authorships and paid citations, researchers say organized groups are manipulating the academic publishing system. To investigate the issue, scientists combined large scale analysis of scientific publications with detailed case studies. While misconduct is often portrayed as the work of individual researchers cutting corners, the Northwestern team discovered something far more complex. Their findings reveal global networks of people and organizations working together to systematically exploit weaknesses in the publishing process. According to the researchers, fraudulent studies are now appearing at a faster rate than legitimate scientific publications. "Science must police itself better in order to preserve its integrity," said Northwestern's Luís A. N. Amaral, the study's senior author. Some people worry that talking about this issue is attacking science. But I strongly believe we are defending science from bad actors. Reese Richardson, a postdoctoral fellow in Amaral's laboratory, is the study's first author. When the public hears about scientific fraud, the focus often falls on isolated cases involving falsified data, plagiarism or retracted studies. These incidents typically involve a single researcher attempting to advance their career by taking shortcuts in a highly competitive environment. Their analysis revealed an extensive underground network operating largely out of public view. "These networks are essentially criminal organizations, acting together to fake the process of science," Amaral said. Much of the information came from major scientific databases, including Web of Science (WoS), Elsevier's Scopus, National Library of Medicine's PubMed/MEDLINE and OpenAlex, which includes data from Microsoft Academic Graph, Crossref, ORCID, Unpaywall and other institutional repositories. The researchers also gathered lists of de indexed journals. These are academic journals that databases have removed because they failed to meet quality or ethical standards. Paper mills function like production lines for academic manuscripts. These manuscripts often contain fabricated data, manipulated or stolen images, plagiarized text and sometimes claims that are scientifically impossible. "Paper mills operate by a variety of different models," Richardson added. "So, we have only just been able to scratch the surface of how they operate. But they sell basically anything that can be used to launder a reputation. They often sell authorship slots for hundreds or even thousands of dollars. A person might pay more money for the first author position or less money for a fourth author position. People also can pay to get papers they have written automatically accepted in a journal through a sham peer-review process." To detect additional papers produced through these operations, Amaral's group launched a separate project that automatically scans published materials science and engineering studies. Findings from that work were accepted for publication in the journal PLOS ONE. The team found that fraudulent networks rely on several strategies to spread fake research. In some cases, these groups avoid legitimate journals entirely and instead take over abandoned ones. When a legitimate publication stops operating, fraudsters may acquire the website or domain name and revive it as a vehicle for fraudulent publishing. "This happened to the journal HIV Nursing," Richardson said. "It was formerly the journal of a professional nursing organization in the U.K., then it stopped publishing, and its online domain lapsed. An organization bought the domain name and started publishing thousands of papers on subjects completely unrelated to nursing, all indexed in Scopus." This includes closer monitoring of editorial practices, stronger tools to detect fabricated studies, deeper understanding of the networks enabling fraud and major changes to the incentive systems that drive scientific publishing. Amaral said the project was personally discouraging but necessary. "This study is probably the most depressing project I've been involved with in my entire life," Amaral said.

New archaeological research suggests that seabird guano, nutrient-rich bird droppings, played a major role in transforming agriculture in ancient Peru and may have helped propel the Chincha Kingdom to prominence as one of the most prosperous and influential societies before the Inca. "Seabird guano may seem trivial, yet our study suggests this potent resource could have significantly contributed to sociopolitical and economic change in the Peruvian Andes," Dr. Bongers said. "Guano dramatically boosted the production of maize (corn), and this agricultural surplus crucially helped fuel the Chincha Kingdom's economy, driving their trade, wealth, population growth and regional influence, and shaped their strategic alliance with the Inca Empire. This region once supported a powerful coastal society with an estimated population of around 100,000 people. Laboratory analysis showed extremely high nitrogen levels in the maize. These levels far exceeded what the surrounding soils could naturally produce. The results strongly suggest the crops were fertilized with seabird guano, which is rich in nitrogen because seabirds feed on marine life. "The guano was most likely harvested from the nearby Chincha Islands, renowned for their abundant and high-quality guano deposits," Dr. Bongers said. "Colonial-era writings we studied report that communities across coastal Peru and northern Chile sailed to several nearby islands on rafts to collect seabird droppings for fertilization." "Together, the chemical and material evidence we studied confirms earlier scholarship showing that guano was deliberately collected and used as a fertilizer," Dr. Bongers said. "But it also points to a deeper cultural significance, suggesting people recognized the exceptional power of this fertilizer and actively celebrated, protected and even ritualized the vital relationship between seabirds and agriculture." Dr. Emily Milton, a postdoctoral fellow at the Smithsonian Institution in Washington, D.C., said combining multiple research approaches was key to understanding the practice. "Our work extends the known geographic extent of guano fertilization, echoing recent findings in northern Chile, and suggests soil management began at least around 800 years ago in Peru." Farming in One of the Driest Places on Earth Guano transported from offshore islands offered farmers a powerful and renewable fertilizer that made it possible to grow large quantities of maize in the Chincha Valley. The ability to grow it in abundance produced agricultural surpluses that supported merchants, farmers and fisherfolk. This prosperity helped the Chincha develop into major coastal traders. Maize held enormous cultural importance for the Inca and was used to make ceremonial fermented beer called 'chicha'. Coauthor Dr. Jo Osborn of Texas A&M University said the findings encourage a broader rethink of how wealth and power functioned in the ancient Andes. "The true power of the Chincha wasn't just access to a resource; it was their mastery of a complex ecological system," she said. Their art celebrates this connection, showing us that their power was rooted in ecological wisdom, not just gold or silver." He has suggested that this site may have served as an ancient marketplace operated by the Chincha Kingdom. "This research adds another layer to our understanding of how the Chincha, and potentially other coastal communities, used resources, trade and agriculture to expand their influence in the pre-Hispanic era," Dr. Bongers said.
