The find overturns the classic “ape-to-human” progression and paints human evolution as a crowded, branching tree with multiple species coexisting. Scientists dated the fossils using volcanic ash deposits and are now investigating what these ancient relatives ate and whether they competed for resources.

Researchers say Eilmer of Malmesbury recognized that the blazing comet seen in 1066 was the same one he had witnessed in 989. At the time, comets were viewed as terrifying omens tied to war and royal deaths, adding even more drama to the famous celestial event shown in the Bayeux Tapestry. The discovery is sparking debate over whether Halley’s Comet deserves a different name.

Yet archaeological evidence from Africa and Asia suggests early humans were far more resilient than once thought. Instead of disappearing, some communities adapted with new tools, new survival strategies, and remarkable flexibility. The disaster may not have destroyed humanity — it may have revealed just how tough humans really are.

New research argues that the 14th-century poet essentially imagined a catastrophic asteroid impact centuries before modern science understood meteors. In this interpretation, Satan crashes into Earth like a giant cosmic object, blasting through the Southern Hemisphere and reshaping the planet itself — carving out the circles of Hell while forcing up Mount Purgatory on the opposite side of the globe.

Because conversational AI often validates and builds on what users say, it can make distorted memories, conspiracy theories, or delusions feel more believable and emotionally real. Researchers warn that AI companions may be especially risky for isolated or vulnerable people seeking reassurance and connection. Mon, 11 May 2026 00:13:50 EDT https://www.sciencedaily.com/releases/2026/05/260509210652.htm https://www.sciencedaily.com/releases/2026/05/260508003113.htm Scientists in China discovered that ancient humans were making surprisingly advanced stone tools during a harsh ice age 146,000 years ago. The tools, created by Homo juluensis, show careful planning and complex thinking rather than simple stone-chipping. Researchers dated the site using tiny calcite crystals inside animal bones, revealing the tools are much older than expected. The discovery challenges the idea that human creativity only thrives in easy, prosperous times. Sat, 09 May 2026 06:22:50 EDT https://www.sciencedaily.com/releases/2026/05/260508003113.htm https://www.sciencedaily.com/releases/2026/05/260506225231.htm Centuries ago in England, hats weren’t just accessories—they were statements of power and rebellion. Refusing to remove a hat could challenge authority, even in courtrooms and before kings. People valued their hats so deeply that robbery victims sometimes begged to keep them over money. In a world where going bareheaded signaled poverty or madness, hats shaped identity, respect, and even family discipline.

People who lose weight using these medications may actually face more judgment than those who lose weight through diet and exercise—or even those who don’t lose weight at all. The stigma seems rooted in a perception that these drugs are an “easy way out,” creating a double bind where individuals are judged both for their weight and for how they choose to manage it. Tue, 05 May 2026 14:04:18 EDT https://www.sciencedaily.com/releases/2026/05/260504154016.htm https://www.sciencedaily.com/releases/2026/05/260504074826.htm After centuries of mystery, scientists are edging closer to uncovering Leonardo da Vinci’s biological secrets. A massive 30-year effort has mapped his family across 21 generations, identified living male descendants, and even confirmed shared DNA markers that stretch back to the Renaissance. Meanwhile, excavations at a family tomb in Vinci could provide ancient remains for comparison, raising the possibility of reconstructing Leonardo’s genetic profile. Mon, 04 May 2026 08:46:48 EDT https://www.sciencedaily.com/releases/2026/05/260504074826.htm https://www.sciencedaily.com/releases/2026/05/260504023848.htm Long-forgotten ancient tablets have been decoded, uncovering a mix of magic, politics, and daily life from early civilizations. Among the discoveries are rare anti-witchcraft rituals meant to protect kings and a regnal list that could point to the real-life existence of Gilgamesh. Some texts reveal correspondence between rulers, while others show the rise of complex bureaucracies. One tablet even records something as ordinary—and relatable—as a receipt for beer. Tue, 05 May 2026 12:59:02 EDT https://www.sciencedaily.com/releases/2026/05/260504023848.htm https://www.sciencedaily.com/releases/2026/05/260504023837.htm Artemis II proved NASA’s deep space systems are ready for the next leap. Orion survived its high-speed return with improved heat shield performance and pinpoint landing accuracy, while the SLS rocket nailed its trajectory. Even the launch pad upgrades paid off, with minimal damage despite the powerful liftoff. With only minor issues to resolve, NASA is now gearing up for Artemis III and future Moon missions. Mon, 04 May 2026 07:45:06 EDT https://www.sciencedaily.com/releases/2026/05/260504023837.htm https://www.sciencedaily.com/releases/2026/05/260502233859.htm Long before humans spread across the globe, a deadly disease may have quietly shaped where our ancestors lived—and even how we evolved. New research reveals that malaria didn’t just threaten early human survival; it actively pushed populations away from high-risk regions across Africa, fragmenting groups over tens of thousands of years. This separation influenced how different populations met, mixed, and exchanged genes, helping shape the genetic diversity we see today. Sun, 03 May 2026 12:04:21 EDT https://www.sciencedaily.com/releases/2026/05/260502233859.htm https://www.sciencedaily.com/releases/2026/04/260427050637.htm The mysterious collapse of the Maya civilization may not have been driven solely by drought after all. New evidence from lake sediments in Guatemala reveals that one key city, Itzan, enjoyed a stable climate even as its population abruptly vanished. Instead of environmental collapse, the findings point to something more complex: a tightly interconnected network of cities unraveling under pressure. As drought struck neighboring regions, wars, migration, and economic breakdown likely rippled outward, dragging even stable communities into decline. Mon, 27 Apr 2026 23:44:14 EDT https://www.sciencedaily.com/releases/2026/04/260427050637.htm https://www.sciencedaily.com/releases/2026/04/260427050609.htm A new study suggests Neanderthals didn’t go extinct simply because of climate change or competition with Homo sapiens. Instead, the key difference may have been social connectivity—Homo sapiens formed stronger, more flexible networks that helped them survive environmental shocks. Neanderthals had connections too, but they were more fragile and regionally limited. This made them less resilient as conditions became increasingly unpredictable. Tue, 28 Apr 2026 04:42:03 EDT https://www.sciencedaily.com/releases/2026/04/260427050609.htm https://www.sciencedaily.com/releases/2026/04/260426012255.htm Scientists have uncovered a surprising new picture of human origins that challenges the long-held idea of a single ancestral population in Africa. By analyzing genetic data from diverse modern African groups—especially the highly distinct Nama people—and comparing it with fossil evidence, researchers found that early humans likely evolved from multiple intermingling populations over hundreds of thousands of years. Rather than a clean split, these groups stayed connected, exchanging genes even after beginning to diverge around 120,000–135,000 years ago. Sun, 26 Apr 2026 06:53:10 EDT https://www.sciencedaily.com/releases/2026/04/260426012255.htm https://www.sciencedaily.com/releases/2026/04/260426012250.htm The famous mezcal “worm” has long puzzled scientists, but DNA testing has finally cracked the case. Researchers found that all sampled larvae were actually agave redworm moth caterpillars—not a mix of species as once believed. While the discovery clears up a long-standing mystery, it also raises concerns about sustainability. Growing demand for mezcal and edible larvae could put pressure on wild populations and the agave plants they depend on. Sun, 26 Apr 2026 09:34:14 EDT https://www.sciencedaily.com/releases/2026/04/260426012250.htm https://www.sciencedaily.com/releases/2026/04/260424233204.htm Beneath East Africa’s Turkana Rift, scientists have found the crust is thinning to a critical point, suggesting the continent is gradually breaking apart. This “necking” process marks an advanced stage of rifting that could eventually lead to a new ocean forming millions of years from now. Surprisingly, the same geological forces that are splitting the land may also explain why the region holds such a rich fossil record. Instead of being the birthplace of humanity, Turkana may just be where the story was best preserved. Sat, 25 Apr 2026 12:26:15 EDT https://www.sciencedaily.com/releases/2026/04/260424233204.htm https://www.sciencedaily.com/releases/2026/04/260423031540.htm A newly confirmed mass grave in ancient Jordan offers chilling insight into one of history’s first pandemics. Hundreds of plague victims were buried within days, revealing how the Plague of Justinian devastated entire communities. The findings show that people who usually lived spread out across regions were suddenly concentrated in death. It’s a powerful reminder that pandemics don’t just spread disease—they reshape how societies live and collapse. Thu, 23 Apr 2026 17:44:05 EDT https://www.sciencedaily.com/releases/2026/04/260423031540.htm https://www.sciencedaily.com/releases/2026/04/260423031516.htm Scientists are making a major leap toward freezing organs for future use without damaging them. A new study reveals that one of the biggest obstacles—cracking during ultra-cold preservation—can be reduced by carefully tuning the temperature at which tissues enter a glass-like state. This breakthrough builds on recent successes in cryopreserved organ transplants and could bring the long-imagined idea of “banking” organs for later use much closer to reality. Mon, 27 Apr 2026 10:02:30 EDT https://www.sciencedaily.com/releases/2026/04/260423031516.htm https://www.sciencedaily.com/releases/2026/04/260421042800.htm Ancient DNA from a tomb near Paris reveals a shocking prehistoric reset: one population vanished and was replaced by newcomers from the south. The two groups show no genetic connection, signaling a major upheaval around 3000 BC. Disease, including early plague, likely played a role, but wasn’t the only cause. The change also reshaped society, ending tightly knit family burials and coinciding with the disappearance of Europe’s megalith builders. Wed, 22 Apr 2026 07:57:10 EDT https://www.sciencedaily.com/releases/2026/04/260421042800.htm https://www.sciencedaily.com/releases/2026/04/260421042755.htm A light-sensitive crystal is opening the door to a new era of “light-written” technology. Arsenic trisulfide can be reshaped and permanently altered using simple light, creating ultra-fine optical patterns without expensive manufacturing tools. Scientists even etched a nanoscale portrait of Einstein and high-density patterns that could act as secure optical signatures. This breakthrough could power everything from advanced sensors to next-generation AR devices.

Unlike traditional bots, they adapt, coordinate, and refine their messaging at a massive scale, creating a false sense of consensus. Early warning signs—like deepfakes and fake news networks—have already appeared in global elections. Researchers warn that the next election could be the true test of this technology’s power. Mon, 20 Apr 2026 05:47:25 EDT https://www.sciencedaily.com/releases/2026/04/260420014748.htm https://www.sciencedaily.com/releases/2026/04/260419054825.htm Human societies didn’t just adapt to the planet—they learned to reshape it. From early fire use to today’s global supply chains, our cultural and social innovations have unlocked extraordinary power to transform Earth and improve human life. But that progress has come with serious costs, including climate change, pollution, and mass extinction. Instead of framing this era—the Anthropocene—as pure crisis, Erle Ellis argues it’s also proof of something hopeful: when people work together, they can drive massive positive change.

A new study shows that news writers are more careful than expected, rarely using strongly human-like language. When they do, it often falls on a spectrum—sometimes describing simple requirements, other times hinting at human traits. Sun, 19 Apr 2026 04:02:23 EDT https://www.sciencedaily.com/releases/2026/04/260417224505.htm https://www.sciencedaily.com/releases/2026/04/260416071945.htm The ozone layer has been on track to recover thanks to the Montreal Protocol—but a loophole may be holding it back. Chemicals still permitted for industrial use are leaking into the atmosphere at higher rates than expected. Scientists now estimate this could delay ozone recovery by up to seven years. Closing this gap could speed up healing and reduce harmful UV exposure worldwide.

Researchers found that sharper thinking on a given day leads people to set bigger goals and actually follow through. That edge can equal up to 40 extra minutes of productivity. But push too hard for too long, and the effect reverses. Wed, 15 Apr 2026 08:44:11 EDT https://www.sciencedaily.com/releases/2026/04/260415043626.htm https://www.sciencedaily.com/releases/2026/04/260409101057.htm Earth’s nights are steadily getting brighter overall, but the changes vary dramatically by region. Rapid urban growth is lighting up countries like China and India, while parts of Europe are dimming due to energy-saving efforts and new lighting technologies. The most detailed satellite analysis yet shows these shifts happening faster and more unevenly than expected. Even global trends can mask sharp local contrasts, from war-related blackouts to deliberate reductions in light pollution. Thu, 09 Apr 2026 10:50:38 EDT https://www.sciencedaily.com/releases/2026/04/260409101057.htm https://www.sciencedaily.com/releases/2026/04/260408225938.htm Scientists have uncovered compelling evidence that humans reached New Guinea and Australia around 60,000 years ago—earlier than some recent theories suggested. By tracing maternal DNA lineages, the team discovered that these early travelers likely used at least two different migration routes through Southeast Asia. This points to sophisticated navigation and seafaring skills far earlier than once believed. The research helps clarify a long-standing mystery about how humans spread across the globe. Thu, 09 Apr 2026 00:14:47 EDT https://www.sciencedaily.com/releases/2026/04/260408225938.htm https://www.sciencedaily.com/releases/2026/04/260407193923.htm Early wheat didn’t just grow—it fought. When humans began cultivating fields, plants that could outcompete their neighbors for sunlight and space quickly took over, evolving upright leaves and aggressive growth. These ancient “warrior” traits helped wheat thrive for millennia. Ironically, modern farming now favors less competitive plants, prioritizing yield over survival battles. Wed, 08 Apr 2026 09:51:27 EDT https://www.sciencedaily.com/releases/2026/04/260407193923.htm https://www.sciencedaily.com/releases/2026/04/260407193911.htm A new international study is shaking up how we think about elite sprinting, arguing there’s no single “perfect” running style behind the world’s fastest athletes. Instead, speed emerges from a complex mix of an individual’s body, coordination, strength, and training—meaning every top sprinter moves differently. Using examples like rising Australian star Gout Gout, researchers show that unique physical traits can produce world-class speed without copying anyone else’s technique. Wed, 08 Apr 2026 09:17:58 EDT https://www.sciencedaily.com/releases/2026/04/260407193911.htm https://www.sciencedaily.com/releases/2026/04/260405003943.htm A massive new analysis of over 1,700 languages shows that some long-debated “universal” grammar rules are actually real. By using cutting-edge evolutionary methods, researchers found that languages tend to evolve in predictable ways rather than randomly. Key patterns—like word order and grammatical structure—keep reappearing across the globe. The results suggest shared human thinking and communication pressures shape how all languages develop.

These bone “binary lots” acted like primitive coins, producing random outcomes for games of chance. A new study shows these weren’t accidental objects but carefully designed tools used across many regions and cultures.

Scholars now think the mosque sits atop a sacred site that transitioned from pagan worship to Christianity and then Islam. The find supports the idea that religious change in the region happened gradually, with overlapping beliefs rather than sudden shifts. It also reconnects the site to the powerful cult of Elagabalus, whose priest once became a Roman emperor.

A University of Michigan study found that common nitrile and latex gloves release tiny particles called stearates, which closely resemble microplastics and can contaminate samples during testing. In some cases, this led to wildly exaggerated results, forcing researchers to track down the unexpected culprit.

While many assume processed foods are the worst, they tend to overlook the surprisingly high impact of items like nuts and underestimate how damaging beef really is. These misunderstandings come from relying on simple categories like “animal vs. plant” rather than the full picture.

The unusual, claw-like design hints at early symbolic thinking and possibly spiritual beliefs. This discovery also strengthens the case that humans reached Australia at least 65,000 years ago. It offers rare insight into the creative lives of some of our earliest ancestors.

Centuries later, a stressed group of maize-heavy farmers migrated into the region, facing climate instability, disease, and declining numbers. Despite these pressures, there’s no sign of violence—instead, families stayed connected across generations, using kinship networks to survive. The research shows how cooperation, not conflict, helped communities navigate crisis.

Scientists found that enzymes already present in wheat, activated by the sourdough’s acidic environment, break down key fibres called arabinoxylans. This process may influence the bread’s texture, digestibility, and flavor. Some microbes even create buttery or subtly sweet notes that give sourdough its distinctive taste.

Researchers from the University of Bonn found that kids exposed to the food price surge were more likely to experience stunted growth and, years later, a higher risk of obesity. The findings suggest that during crises, families often maintain calorie intake but cut back on nutrient-rich foods, creating hidden nutritional deficiencies that disrupt healthy development.

In response, nearly 1,000 experts created Humanity’s Last Exam, a massive 2,500-question challenge covering highly specialized topics across many fields. The exam was engineered so that any question solvable by current AI models was removed. Early results show even the most advanced systems still struggle — revealing a surprisingly large gap between AI performance and true expert-level knowledge.

But when researchers examined hundreds of skeletons, they discovered something unexpected: even people with stigmatized diseases like leprosy were buried in these high-status spots. Instead of excluding the sick, many communities appear to have treated them much like everyone else.

Researchers studying a Swiss high school that introduced flexible start times found that students overwhelmingly chose to begin later—and ended up sleeping about 45 minutes longer each school night. The extra rest led to fewer sleep problems, better well-being, and improved academic performance.

Using radar imaging, researchers can detect millimeter-scale movements that may signal early structural problems long before inspectors notice them. The study found many bridges—especially in North America—are aging and increasingly vulnerable, but satellite monitoring could sharply reduce the number classified as high-risk. The approach could be especially valuable in regions where traditional monitoring barely exists.

By analyzing massive datasets of publications, retractions, and editorial records, researchers uncovered networks involving “paper mills,” brokers, and compromised journals that systematically produce and sell fake research, authorship slots, and citations.

Scientists analyzing ancient DNA discovered the bacterium Yersinia pestis in a 4,000-year-old domesticated sheep from a Bronze Age settlement in the Ural Mountains—the first time the pathogen has ever been found in a non-human host from that era. Because this early strain couldn’t spread through fleas like the medieval plague, researchers have long puzzled over how it traveled so widely.

Chemical clues in centuries-old maize show farmers fertilized their crops with guano gathered from nearby islands, dramatically boosting yields in the desert landscape. The resulting agricultural surplus fueled trade, population growth, and regional influence.

Growth lines in the enamel reveal moments of early-life stress, while hardened plaque holds microscopic remains of cereals, legumes, and fermented foods. The findings suggest a community with diverse food resources and strong Mediterranean connections. Even a small sample offers a striking glimpse into how people lived, grew, and ate nearly three millennia ago.

Researchers found that people who eat more fruits and vegetables known to carry higher pesticide residues—such as strawberries, spinach, and bell peppers—also have significantly higher levels of those chemicals in their urine. While produce remains a cornerstone of a healthy diet, the findings highlight how everyday food choices can drive real-world exposure to substances linked to cancer, hormone disruption, and developmental harm.

A new U.S. Department of Energy–sponsored report urges major investment in advanced diagnostic tools—the high-tech “sensors” that track plasma temperature, density, and behavior inside fusion systems. Bringing together 70 experts from universities, national labs, and private industry, the workshop identified seven priority areas ranging from burning plasma to full-scale pilot plants.

New research suggests it’s not just about rewarding good service, but about social pressure. Some people tip out of genuine appreciation, while others simply follow the norm. But here’s the twist: those who truly value great service tend to tip more than average, and everyone else adjusts upward to match them.
