Historians and archaeologists know that maize was a central food source and cultural symbol across the ancient Maya world, but much of what is known has come from studies focused on large Maya cities and elite burials.
Ecologists have long understood that biodiversity is paramount to ecosystem stability. Until now, however, most ecological research has focused on a single layer of ecological life at a time—for example, plant or animal communities. In reality, ecological systems have multiple la
Long-lived ytterbium states could sharpen quantum computing and atomic clocks and more — today's student signal.
Researchers from the University of Amsterdam and the University of New South Wales have answered a question that has been around for decades: whether ions of the metal ytterbium can enter certain long-lived, nearly stable states and, if so, for how long. The measured long-lived s
Imagine searching for a gemstone in a dark cave: You use a flashlight, looking for a rainbow-colored glint in the darkness. Now, imagine 10 other people in the cave with you, using different-colored flashlights at the same time. Suddenly, you can no longer tell which light is com
Researchers at NYU Abu Dhabi have discovered that the malaria parasite relies on a specific type of fat to survive and multiply within the human host, uncovering a previously unknown vulnerability that could help guide future treatments.
As the climate becomes increasingly variable and extreme events become more frequent, accelerating the use of innovations that can strengthen agricultural resilience has become a priority for agrifood systems. Science has made progress in developing solutions with the potential t
When scientists want to create a protein that can potentially treat disease, one approach is to begin with a different protein and evolve it in the lab, selecting over many generations for versions with a new, desired function.
Rejection can sometimes be so intense it feels like physical pain—a punch in the gut or a heart that aches. It often involves feeling left out and unwanted. And it can make us question our self-worth.
Children thrive when parents are warm and responsive to their needs while also providing clear guidance and setting limits. This is known as authoritative parenting. But most parents will tell you authoritative parenting is easier said than done, especially when children have fre
Millions of people living on tropical islands could face a future of increasingly dangerous heat as climate change drives longer and more intense periods of humid conditions. While rising temperatures are often discussed as the main consequence of climate change, humidity plays a
Researchers explore classroom applications of AI new learning platforms and more — today's student signal.
People who receive information on social media play a greater role in the spread of misinformation than research has acknowledged, according to research published in the International Journal of Enterprise Network Management. The researchers argue that efforts to tackle "fake new
Whale sharks (Rhincodon typus)—the world's biggest fish—are one of the most charismatic marine species. They connect with the hearts of anyone lucky enough to encounter them, making people deeply curious about their lives and invested in their conservation.
Authorities have evacuated more than 340,000 people and suspended work and rail services as Typhoon Noul approaches southern China, with flight cancellations announced in Hong Kong.
Spain's Prime Minister Pedro Sánchez said Saturday firefighters were working to "save lives" in the blazes raging west of Madrid, as authorities said a separate fire in the east killed one person.
SpaceX's mammoth Starship rocket blasted off Friday on another test flight stretching halfway around the world, this time releasing 20 of the most advanced Starlinks.
All cells in the human body—and the motions they enable, from our beating hearts to our wiggling toes—use energy generated by a molecule called ATP. Its energy is thought to be released to fuel cellular processes in only one way: when ATP's decomposition is initiated by an enzyme

Recycling, greener diets, and other personal climate choices do not seem to distract people from supporting major environmental reforms. A four-year study of nearly 2,800 Australians found that these habits neither increased nor reduced later political engagement.
Cosmic expansion allows distant galaxies to move away faster than light, while still letting us see ancient light they emitted when they were much closer. Eventually, accelerating expansion will push nearly every galaxy beyond our Local Group out of sight, making the Universe app
Chinese astronomers report the detection of a peculiar optical transient event that occurred in the center of a dwarf galaxy. The newly discovered event, designated AT2019ijn, is a fast-rising, slow-decaying blue optical transient with exceptionally bright radio emission. The fin
Modern research on secondary metabolites from microbes, plants and marine organisms has revealed a remarkable diversity of chemical structures and bioactivities with broad applications in biotechnology, agriculture and medicine. Most natural products are composed of primary bioge
