Peter J. Denning argues that the most important parts of human intelligence, including common sense, intuition, culture, and practical know-how, cannot be encoded into computers. He believes this makes true human-level AI impossible, regardless of how large language models become.

The findings show that leftover debris, fine particles, and airborne chemicals may affect ecosystems and increase people's exposure to air pollution during major celebrations. Fri, 03 Jul 2026 22:48:09 EDT https://www.sciencedaily.com/releases/2026/07/260701205009.htm https://www.sciencedaily.com/releases/2026/06/260626030443.htm Claims that Neanderthal men "preferred" Homo sapiens women may make for catchy headlines, but the underlying research does not actually show prehistoric romance. The genetic evidence only points to an uneven pattern of DNA inheritance, which could have been shaped by biology, migration, or social organization. Archaeological evidence suggests Neanderthal groups may have followed traditions where women moved between communities, opening the door to far more complicated explanations than simple attraction. Tue, 07 Jul 2026 02:47:40 EDT https://www.sciencedaily.com/releases/2026/06/260626030443.htm https://www.sciencedaily.com/releases/2026/06/260624115624.htm Scientists discovered ancient wolves on a tiny Baltic island where they could only have been brought by humans, suggesting an unexpectedly close relationship between people and wolves thousands of years ago. Evidence indicates the wolves were fed, possibly cared for, and may even have been managed or selectively bred long before modern ideas of domestication. Sun, 05 Jul 2026 17:54:12 EDT https://www.sciencedaily.com/releases/2026/06/260624115624.htm https://www.sciencedaily.com/releases/2026/06/260623083146.htm What if consciousness isn’t limited to brains like ours? Philosophers Eric Schwitzgebel and Jeremy Pober argue that consciousness could arise in many different forms of life, even in beings built from radically different materials than those found on Earth. Drawing on the vastness of the universe and the likely existence of countless alien civilizations, they suggest it would be surprisingly Earth-centric to assume that only Earth-like biology can support conscious experience. Wed, 24 Jun 2026 10:49:57 EDT https://www.sciencedaily.com/releases/2026/06/260623083146.htm https://www.sciencedaily.com/releases/2026/06/260623083123.htm A new study suggests early humans were using fire in South Africa’s Wonderwerk Cave as far back as 1.79 million years ago. Researchers found burned bones deep inside the cave, where natural wildfires could not have reached, indicating that fire was likely carried in and maintained by human ancestors. The discovery pushes back the timeline for fire use and reveals surprisingly sophisticated behavior long before humans could create fire on demand. Wed, 24 Jun 2026 05:12:51 EDT https://www.sciencedaily.com/releases/2026/06/260623083123.htm https://www.sciencedaily.com/releases/2026/06/260623083121.htm Scientists are raising concerns that we may be overlooking evidence of extraterrestrial life even when it is present. Hidden biosignatures, limitations in detection technology, and assumptions about what life should look like can all create dangerous false negatives. The researchers say future missions should focus not only on finding life, but also on understanding how signs of life could be missed. Mon, 29 Jun 2026 22:34:31 EDT https://www.sciencedaily.com/releases/2026/06/260623083121.htm https://www.sciencedaily.com/releases/2026/06/260623014006.htm A massive national study found that nearly half of Americans with kidney failure who are referred for a transplant never even begin the evaluation process, and only 19% make it onto the transplant waitlist. Researchers discovered that factors such as where a person lives, whether they are married, their income level, language, age, and even which transplant center they use can dramatically affect their chances of moving forward. Wed, 01 Jul 2026 16:10:45 EDT https://www.sciencedaily.com/releases/2026/06/260623014006.htm https://www.sciencedaily.com/releases/2026/06/260618041511.htm Despite centuries of study, scientists are still finding new details and even overlooked structures within the human body. As researchers explore anatomical differences between individuals, it’s becoming clear that the body is far more complex—and less fully understood—than textbooks suggest. Sun, 21 Jun 2026 03:26:53 EDT https://www.sciencedaily.com/releases/2026/06/260618041511.htm https://www.sciencedaily.com/releases/2026/06/260618041450.htm Plague was already a deadly killer 5,500 years ago, long before cities, farming, or the rat-infested conditions usually linked to historic outbreaks. By analyzing ancient DNA from hunter-gatherer cemeteries in Siberia, researchers discovered early plague strains in nearly 40% of the individuals studied and found evidence of rapid family-based outbreaks that wiped out many children and young teenagers. Thu, 18 Jun 2026 08:16:46 EDT https://www.sciencedaily.com/releases/2026/06/260618041450.htm https://www.sciencedaily.com/releases/2026/06/260614012006.htm Humans evolved to pay close attention to danger, but today that instinct is being overwhelmed by an endless supply of bad news from around the world. Researchers say the answer isn’t to stop following current events—it’s to build healthier habits around how, when, and where we get our news. Tue, 16 Jun 2026 03:32:55 EDT https://www.sciencedaily.com/releases/2026/06/260614012006.htm https://www.sciencedaily.com/releases/2026/06/260613215510.htm One of the most celebrated claims about Yellowstone’s wolves is facing a major challenge. Scientists say the study behind the famous trophic cascade story relied on flawed methods that overstated the ecological impact of wolf recovery. Their reanalysis found no evidence for a dramatic, park-wide surge in willow growth. Instead, the effects appear smaller and vary from place to place. Sun, 14 Jun 2026 00:27:09 EDT https://www.sciencedaily.com/releases/2026/06/260613215510.htm https://www.sciencedaily.com/releases/2026/06/260613215430.htm A new international study finds that middle-aged Americans are lonelier, more depressed, and experiencing worse memory and health than earlier generations. Researchers say growing financial strain, weaker social supports, and chronic stress may explain why the U.S. is falling behind other wealthy nations. Sat, 13 Jun 2026 22:24:12 EDT https://www.sciencedaily.com/releases/2026/06/260613215430.htm https://www.sciencedaily.com/releases/2026/06/260613034206.htm A child psychologist says grandparents are more important than ever as youth mental health challenges continue to rise. He argues that children need supportive relationships, meaningful conversations, and a sense of purpose—not just pressure to achieve. Grandparents can help by listening, encouraging, and creating positive experiences that strengthen emotional resilience. Sat, 13 Jun 2026 05:11:52 EDT https://www.sciencedaily.com/releases/2026/06/260613034206.htm https://www.sciencedaily.com/releases/2026/06/260612032029.htm A new experimental vaccine developed by Scripps Research could offer a powerful new way to prevent fentanyl overdoses by stopping the drug before it reaches the brain. Rather than targeting only fentanyl itself, the vaccine trains the immune system to recognize a broad range of fentanyl-related designer drugs, including some of the most dangerous variants. Sat, 13 Jun 2026 01:35:08 EDT https://www.sciencedaily.com/releases/2026/06/260612032029.htm https://www.sciencedaily.com/releases/2026/06/260612021000.htm Researchers in South Korea have recreated the legendary “sea silk” once prized by emperors, using fibers from a clam cultivated in Korean coastal waters. They discovered that its famous golden shine comes from tiny protein structures that reflect light rather than from pigments or dyes. Because the color is built into the fiber’s structure, it can remain vibrant for centuries. Fri, 12 Jun 2026 03:02:55 EDT https://www.sciencedaily.com/releases/2026/06/260612021000.htm https://www.sciencedaily.com/releases/2026/06/260611024612.htm A tiny set of ancient genetic “switches” may have played a surprisingly large role in making human language possible. Researchers found that these DNA regions, which act like volume controls for genes involved in brain development, have an outsized influence on language ability despite making up less than 0.1% of the genome. Fri, 12 Jun 2026 01:13:27 EDT https://www.sciencedaily.com/releases/2026/06/260611024612.htm https://www.sciencedaily.com/releases/2026/06/260610003056.htm For nearly 700 years, Indigenous hunters repeatedly used a bison kill site in central Montana—then suddenly stopped, even though bison were still abundant. Researchers uncovered evidence that recurring, decades-long droughts likely made the site less practical by reducing access to the water needed to process large numbers of animals. At the same time, hunting groups were shifting toward larger, more coordinated operations that required dependable resources and specialized locations. Thu, 11 Jun 2026 09:08:56 EDT https://www.sciencedaily.com/releases/2026/06/260610003056.htm https://www.sciencedaily.com/releases/2026/06/260609025509.htm A surprising study suggests that chemicals introduced to protect the ozone layer may have unintentionally created a growing global pollution problem. Researchers found that refrigerants and certain anesthetic gases have generated more than 335,000 tonnes of trifluoroacetic acid (TFA), a highly persistent "forever chemical," that has been deposited across Earth's surface since 2000. The pollutant is now showing up everywhere from rainwater to remote Arctic ice, and scientists expect levels to keep rising.

The feat would have required extraordinary planning, teamwork, and determination, revealing a surprisingly sophisticated level of organization thousands of years ago. Tue, 09 Jun 2026 04:42:29 EDT https://www.sciencedaily.com/releases/2026/06/260608040003.htm https://www.sciencedaily.com/releases/2026/06/260606075855.htm Ancient grooves on human teeth, once hailed as evidence of tooth-picking, may simply be the result of natural wear, according to a new study of wild primates. The research also revealed that a common modern dental defect appears to be uniquely human, hinting that today's lifestyles may be reshaping our teeth in unexpected ways. Mon, 08 Jun 2026 06:49:32 EDT https://www.sciencedaily.com/releases/2026/06/260606075855.htm https://www.sciencedaily.com/releases/2026/06/260606075515.htm Researchers have solved a decades-old mystery by showing that a cache of 43 helmets found off the Spanish coast is medieval, not Roman. The remarkable discovery exposes a thriving weapons trade network that connected Mediterranean powers during a time of piracy, warfare, and growing demand for military equipment. Mon, 08 Jun 2026 05:42:36 EDT https://www.sciencedaily.com/releases/2026/06/260606075515.htm https://www.sciencedaily.com/releases/2026/06/260605023357.htm Scientists have successfully tested an AI-designed universal coronavirus vaccine in humans for the first time, finding it to be safe and well tolerated. The vaccine generated immune responses against multiple coronaviruses, including SARS-CoV-2, SARS, and related bat viruses with pandemic potential. By targeting features shared across an entire virus family, it aims to provide protection even as viruses evolve.

Researchers are increasingly focusing on the internal mechanisms of brains and computers, concluding that today's AI is likely not conscious while leaving open the possibility for both conscious insects and future machines. Fri, 05 Jun 2026 01:27:32 EDT https://www.sciencedaily.com/releases/2026/06/260604044258.htm https://www.sciencedaily.com/releases/2026/06/260603023914.htm An ancient mountain cave in the Pyrenees may have served as one of the earliest high-altitude mining camps ever discovered, with evidence of repeated visits spanning thousands of years. The find becomes even more intriguing with the discovery of a child’s remains and clues that deeper excavations could uncover prehistoric burials. Wed, 03 Jun 2026 05:10:16 EDT https://www.sciencedaily.com/releases/2026/06/260603023914.htm https://www.sciencedaily.com/releases/2026/05/260529043656.htm Using cannabis edibles and alcohol together may make drivers far more impaired than either substance alone, according to new research from Johns Hopkins. Even more concerning, common field sobriety tests often failed to detect the cannabis-related impairment. Fri, 29 May 2026 09:42:07 EDT https://www.sciencedaily.com/releases/2026/05/260529043656.htm https://www.sciencedaily.com/releases/2026/05/260529043649.htm New DNA evidence shows that Europe’s hunter-gatherers and early farmers interacted far more closely than previously thought, with women likely playing a crucial role in spreading farming across northwestern Europe. Centuries later, the arrival of Bell Beaker migrants triggered another sweeping population transformation that extended all the way to Britain.

Researcher Zhe Zhu found that employees who see tools like ChatGPT and Gemini as helpful collaborators rather than job-stealing rivals tend to be more engaged, adaptable, and optimistic about their careers. Mon, 25 May 2026 07:21:14 EDT https://www.sciencedaily.com/releases/2026/05/260525000448.htm https://www.sciencedaily.com/releases/2026/05/260523103939.htm Scientists have uncovered the oldest known hand-held wooden tools ever used by humans — and they’re an astonishing 430,000 years old. Buried for hundreds of thousands of years at an ancient lakeside site in Greece, the carefully carved wooden objects reveal that early humans were far more skilled and resourceful than once believed. Sun, 24 May 2026 08:22:54 EDT https://www.sciencedaily.com/releases/2026/05/260523103939.htm https://www.sciencedaily.com/releases/2026/05/260522023127.htm Scientists in Germany have demonstrated a startling new form of surveillance: identifying people using nothing more than ordinary WiFi signals. By analyzing how radio waves bounce around a room, researchers can effectively “see” and recognize individuals — even if they are not carrying a device and even if their phone is turned off. Fri, 22 May 2026 23:03:54 EDT https://www.sciencedaily.com/releases/2026/05/260522023127.htm https://www.sciencedaily.com/releases/2026/05/260521072412.htm Many people avoid learning a new language because they remember stressful grammar lessons or fear making mistakes. But language experts say communication, culture, and connection matter far more than perfection. Modern apps, entertainment, travel, and online communities have made learning easier, more social, and surprisingly fun. Thu, 21 May 2026 20:14:13 EDT https://www.sciencedaily.com/releases/2026/05/260521072412.htm https://www.sciencedaily.com/releases/2026/05/260521072404.htm Researchers have discovered how to fine-tune a futuristic type of porous glass that can trap gases like CO2 and hydrogen.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
