The science & discovery headlines that matter, in one email every morning. Free.
Raw, grilled, roasted, stuffed—there are many ways to enjoy bell peppers, also called capsicums, sweet peppers or paprika. Bell peppers originated in Central and South America and belong to the nightshade family along with tomatoes and eggplants.
The fossilized skull of a new species of mysterious meat-eating dinosaur from the Isle of Wight has been rediscovered in the collections of the Natural History Museum after over 100 years in storage.
Scientists have discovered that switching off a protein called Mitch makes human cells burn more fat and prevents new fat cells from developing. The breakthrough builds on experiments in mice that showed remarkable resistance to obesity and improved muscular endurance, raising ho
Study maps the human side of flood risk and more — today's news signal.
When heavy rain hits a city, knowing where water will accumulate is only part of the picture. Who lives in the affected buildings? How might flooding disrupt their lives? And where could additional support make the greatest difference?
How can the identity of pluripotent stem cells be determined more reliably during their differentiation? Researchers from the IUF—Leibniz Research Institute for Environmental Medicine and Heinrich Heine University Duesseldorf have systematically validated marker genes for this pu
Two black holes can collide and merge into one. But could the opposite happen: could a single black hole split into two smaller ones? That question is explored in a new theoretical study: "When Black Holes Admit Pair-of-pants Topologies," published in the journal Physical Review
Climate change is increasing flood risk across the U.K. As floods become more frequent and intense, communities are increasingly encouraged to become resilient and "live with water." Yet in some flood-prone areas, residents are rejecting these calls, concerned that resilience is
In the Northern Hemisphere, days are getting shorter and temperatures are dropping—autumn has arrived. A common sign that winter is coming is trees losing their leaves. But did you know that autumn also sparks changes in animals' sexual behavior—including ours?
With a successful Mars gravity assist in its rearview mirror, NASA's Psyche spacecraft has fired up its thrusters and is accelerating toward the metal-rich asteroid of the same name. During the first leg of its journey, following an October 2023 launch, the mission used its elect
Quantum systems can occupy superpositions, quantum states that combine different possibilities. For instance, a microwave field can be prepared in a superposition of an empty state and a state that contains microwave light.
Light-based method enables precise control of ultrafast electron flow in a scanning tunneling microscope and more — today's news signal.
In 1987, biologists captured the last free-flying condor to transfer it to captivity, and the largest flying North American bird species was officially declared extinct in the wild. Today, after decades of coordinated efforts and millions of dollars spent on captive breeding and
Raw, grilled, roasted, stuffed—there are many ways to enjoy bell peppers, also called capsicums, sweet peppers or paprika. Bell peppers originated in Central and South America and belong to the nightshade family along with tomatoes and eggplants.
Stainless steel is widely used for its corrosion resistance, but it is not invincible. In environments containing chloride ions, such as seawater, pitting corrosion can occur. These pits often start at tiny particles called inclusions embedded in the steel.
Understanding instabilities and turbulence in plasmas is one of the key challenges across a wide range of plasma research fields, including nuclear fusion, astrophysics and laser-plasma physics. In plasmas, slight disturbances can grow due to instabilities, and energy is transfer
Many topics in astronomy and astrophysics are esoteric. There's not much of a relationship between something like the supermassive black hole at the center of the Milky Way and the life of a regular person going about their business. But the sun is different. Its presence in our
The positron is the antimatter counterpart of the electron, identical in mass but carrying an equal and opposite electric charge. Like the electron, it also behaves like a tiny bar magnet, and according to a key prediction of the Standard Model of particle physics, its magnetic m
Current HIV medicines are effective at suppressing the virus in the blood. However, HIV can remain "asleep" or dormant inside certain immune cells and in the brain. These hidden pockets of virus, called HIV reservoirs, are the main reason HIV cannot be cured with today's treatmen
Metallic materials used in extremely cold environments must maintain high strength, ductility and fracture toughness to support applications in aerospace, clean energy, superconducting systems and deep-space exploration. However, traditional alloys often suffer performance degrad
What seabirds eat might seem like a good starting point for identifying species that tend to accumulate plastic in their digestive systems. Yet a recent global analysis suggests that mapping the evolutionary relatives of birds could offer better clues than their diets or feeding
A small device that gently stimulates nerves through the ear could offer a new way to tackle stubborn high blood pressure. In a clinical trial of 63 patients already taking medication, the treatment proved safe, easy to use at home, and well tolerated. Although it did not signifi
A groundbreaking study challenges 70 years of assumptions about how human language works. By analyzing billions of word uses, scientists discovered that meaning is organized around power, danger, and order rather than emotion alone. Even more surprisingly, human language shows a
In places like South Asia, Africa and parts of the Americas, monsoon rains supply water for drinking, crops and hydropower for billions of people. Understanding the patterns that monsoons tend to follow can help people plan for drought risks affecting agriculture, reservoirs and
