In 1532, in the city of Cajamarca, Peru, Spanish conquistador Francisco Pizarro and a group of Europeans took the Inca ruler Atahualpa hostage, setting the stage for the fall of the Inca Empire.
There's a peculiar ritual in many kitchens: reaching past the crisp, pristine tea towel hanging on the oven door to grab the threadbare, slightly graying one shoved in the drawer.
Astronomers want to collect as much data as possible using as many systems as possible. Sometimes that requires coordination between instruments. The teams that run the James Webb Space Telescope (JWST) and the upcoming Atmospheric Remote-sensing Infrared Exoplanet Large-survey
Chalcolithic cornets are conical ceramic vessels produced exclusively during the Chalcolithic period, recovered in abundance at some archaeological sites but absent at others. Their function has long been debated. However, in a study published in Tel Aviv, Sharon Zuhovitzky and
The Swiss job market is a popular location for workers from outside the country. At the end of 2024, the Swiss Federal Statistical Office reported about 400,000 cross-border commuters in Switzerland—that is, people who live outside the country and commute to work in
Two or more graphene layers that are stacked with a small twist angle in relation to each other form a so-called moiré lattice. This characteristic pattern influences the movement of electrons inside materials, which can give rise to strongly correlated states, such as
Families with children who have dyslexia have long pushed lawmakers to respond to a pressing concern: Too many young students struggle for years to learn to read, before schools recognize the problem.
Extreme rainfall is reshaping coastal waters along South Korea's shoreline, flushing nutrients from land into the sea and fueling the growth of algal blooms. A new multi-year study, published in Frontiers in Marine Science, tracked water quality in and around a major river
Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, however, the physical mechanisms underpinning the generation of these fields remain poorly understood. Recently, researchers at McGill University and ETH
It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening.
Concrete is all around you—in the foundation of your home, the bridges you drive over, the sidewalks and buildings of cities. It is often described as the second-most used material by volume on Earth after water.
A new study co-authored by McGill University researchers suggests people can be taught to reject unfair advantages. "We often benefit personally from an unequal distribution of resources, a phenomenon known as advantageous inequity—for example, receiving a higher salary than a
A major new study suggests that eating the Nordic way could help you live significantly longer—while also helping the planet. Researchers from Aarhus University found that people who closely followed the 2023 Nordic dietary guidelines had a 23% lower risk of death compared to
A new Stanford study suggests math struggles may be about more than numbers. Children who had difficulty with math were less likely to adjust their thinking after making mistakes during number comparison tasks. Brain imaging showed weaker activity in regions that help monitor
When Hurricane Katrina struck the U.S. in 2005, nearly 2000 people lost their lives and the cost of the catastrophe exceeded $100 billion. Now, 21 years later, new research from The University of Manchester has found that Katrina left another, less visible legacy long after the
In the face of widespread pessimism about the political fate of the United States and growing political polarization, scholars and citizens across the country are reimagining how American democracy could better serve the needs of the whole population.
The Mediterranean Sea is rapidly changing under ongoing climate change. In the eastern basin, tropicalization is already well documented and driven by a combination of strong warming and the influx of tropical species through the Suez Canal. In contrast, the western
Researchers tracked more than 400 toddlers to see whether mRNA COVID-19 vaccination during or just before pregnancy was linked to autism or developmental delays. After detailed assessments of speech, motor skills, behavior, and social development, they found no meaningful
Scientists have created the most detailed maps yet of how genes control one another inside the brains of people with Alzheimer’s disease. Using a powerful new AI-based system called SIGNET, the team uncovered cause-and-effect relationships between genes across six major brain
Children who spend time learning outside may reap benefits physically, academically, and emotionally, according to a Texas A&M University researcher. Dr. Arianna Pikus, an assistant professor in the College of Education and Human Development who studies how nature can be used
A simple shift in your evening routine may give your heart a measurable boost. In a new study, adults who stopped eating and dimmed the lights three hours before bed and extended their overnight fast by about two hours saw improvements in blood pressure, heart rate, and
Scientists have uncovered a hidden partnership between pancreatic cancer and the nervous system. Support cells in the pancreas lure nerve fibers, which then release signals that accelerate early cancer growth. This creates a self-sustaining loop that helps tumors take hold.
Scientists have developed a powerful new way to trace the journey of water across the planet by reading tiny atomic clues hidden inside it. Slightly heavier versions of hydrogen and oxygen, called isotopes, shift in predictable ways as water evaporates and moves through the
The head of the International Monetary Fund, Kristalina Georgieva, has warned young people will suffer the most as an AI "tsunami" wipes out many entry-level roles in coming years.
The Japanese priest and his parishioners gathered before dawn, hoping that climate change had not robbed them of the chance to experience an increasingly rare communion with the sacred.
It is Carnival season in New Orleans. That means gazillions of green, gold and purple Mardi Gras beads.
The International Space Station returned to full strength with Saturday's arrival of four new astronauts to replace colleagues who bailed early because of health concerns.
The U.S.'s ocean regulator plans to make industry-friendly changes to a longstanding rule designed to protect vanishing whales, prompting criticism from environmental groups who cite the recent death of an endangered whale.
Space's microgravity appears to shift the location of the brains of astronauts—without a clear effect on their health
An international team of scientists has identified how to pinpoint and predict hotspots for some of the most dangerous species of scorpion in the world. The researchers have established the key environmental conditions that determine where lethal, venomous arachnids
Sleeping on a problem might be more powerful than we ever imagined. Neuroscientists at Northwestern University have shown that dreams can actually be nudged in specific directions — and those dream tweaks may boost creativity. By playing subtle sound cues during REM sleep,
Psychedelics can quiet the brain’s visual input system, pushing it to replace missing details with vivid fragments from memory. Scientists found that slow, rhythmic brain waves help shift perception away from the outside world and toward internal recall — almost like dreaming
A massive review of 23 randomized trials found that statins do not cause the vast majority of side effects listed on their labels. Memory problems, depression, sleep issues, weight gain, and many other symptoms appeared just as often in people taking a placebo. Only a few side
Love and hate seem like obvious opposites. Love, whether romantic or otherwise, involves a sense of warmth and affection for others. Hate involves feelings of disdain. Love builds up, whereas hate destroys.
What really holds people back from stepping up as allies in support of their marginalized colleagues? For example, why don't more men say something when they see a colleague or a customer make a sexist remark about a female co-worker?
The deep sea is cold, dark and under immense pressure. Yet life has found a way to prevail there, in the form of some of Earth's strangest creatures.
The 20th-century French philosopher Simone Weil once said that compassion was an impossibility. She said it is "a more astounding miracle than walking on water." The word she used for meeting the needs of the sufferer is not love or charity, but justice. Today, there is plenty
A camera-trap survey conducted throughout 2025 has revealed the bewildering breadth of biodiversity hidden within the Annamite Mountains, a largely unexplored forest haven stretching for 1,100 kilometers through Laos and Vietnam to northeast Cambodia. The Annamites are the sole
After a long search, RIKEN researchers have identified an enzyme crucial for keeping lipid-linked sugar chains in check in yeast cells. This finding, published in the Journal of Cell Biology, reveals a novel regulatory mechanism for sugar-donor levels.
Supermarket shelves can look full despite the food systems underneath them being under strain. Fruit may be stacked neatly, chilled meat may be in place. It appears that supply chains are functioning well. But appearances can be deceiving.
