Colorectal cancer rates are falling among older adults, largely because of increased screening. But researchers are seeing a troubling shift in younger people, with more cases now appearing in adults under 50, including some in their thirties. A new nationwide study from Switzerland found that diagnoses in this age group…

A large clinical trial suggests that taking a daily multivitamin could help slow biological aging in older adults, especially in people whose bodies were aging faster than expected at the start of the study. Researchers from Mass General Brigham analyzed data from older adults who participated in a randomized clinical…

For more than 100 years, scientists have been trying to understand cosmic rays, incredibly powerful particles that travel across the universe at extreme energies. Despite decades of research, many questions about where they come from and how they are accelerated remain unanswered. Now, researchers working with the DAMPE (Dark Matter…

In March 2022, thousands of earthquakes rattled São Jorge Island in Portugal’s Azores archipelago after a huge body of magma (molten rock) surged upward from deep underground, according to a new study led by researchers at UCL (University College London). The magma traveled from more than 20 kilometers beneath Earth’s…

For decades, scientists believed dinosaur fossils were little more than mineralized rock, with any original biological material long since destroyed by time. But an extraordinary study centered on a remarkably preserved Edmontosaurus fossil is challenging that assumption in a major way. Researchers led by the University of Liverpool uncovered strong…

Scientists have uncovered a remarkable variety of marine life hidden deep beneath the waters off Western Australia’s Nyinggulu (Ningaloo) coast, including evidence of giant squid and several species that may be unknown to science. The discovery comes from a Curtin University-led study that explored the Cape Range and Cloates submarine…

People often spot familiar shapes in random places. Maybe you have looked at the clouds and imagined a sailboat, a seahorse, or even your great-aunt Rosemary staring back at you. Scientists call this tendency to find meaningful patterns in randomness “apophenia.” But in some cases, those patterns are very real.…

As the Earth’s surface and lower atmosphere continue to warm, another part of the planet’s atmosphere is doing the opposite. Far above the ground, the upper atmosphere has been cooling significantly for decades. Scientists have long recognized this unusual contrast as one of the clearest signals of human driven climate…

Powerful solar activity can create stunning auroras on Earth, but outside the protection of our planet’s magnetic field, the Sun can become extremely dangerous. Violent eruptions such as solar flares and coronal mass ejections can blast high energy particles through space, creating serious risks for astronauts and spacecraft. Some of…

For decades, scientists believed the Japanese population largely descended from two ancient groups: the Jomon hunter-gatherers who lived in the archipelago for thousands of years, and later migrants from East Asia who brought rice farming and new technologies to Japan. But a major genetic analysis from researchers at RIKEN’s Center…

Scientists have uncovered new evidence that Earth is traveling through a cloud of ancient stellar debris left behind by a long ago exploding star. By studying Antarctic ice that formed tens of thousands of years ago, researchers detected traces of iron-60, a rare radioactive form of iron created during supernova…

Every night around the world, thousands of automated sky cameras watch for flashes of light streaking across the atmosphere. I am one of the scientists who studies these meteors and what they can reveal about our solar system. Popular movies and breaking news alerts usually focus on giant asteroids that…

Macquarie Island sits in one of the most remote parts of the world, halfway between Tasmania and Antarctica. The narrow, windswept island is packed with wildlife. Elephant seals crowd its beaches, king penguins climb its green slopes, and albatrosses glide above the open landscape. But scientists say the island is…

Researchers at UC Davis have developed a light driven technique that converts amino acids, the molecules that make up proteins, into compounds that behave similarly to psychedelics in the brain. These newly created molecules activate serotonin 5-HT2A receptors, which are associated with brain cell growth and are considered promising targets…

Scientists say your daily coffee habit may do more than give you an energy boost. New research suggests that drinking a moderate amount of caffeinated coffee or tea could help lower the risk of dementia as people age. However, the benefits appear to level off after a certain point, meaning…

Reinforced rubber is one of the most important materials in modern life. It helps car and airplane tires withstand enormous stress, keeps industrial machinery running, and appears in everything from medical devices to garden hoses. Despite being used for nearly a century and supporting a global tire industry worth about…

Researchers say the famous comet known as Halley’s Comet may have been identified as a repeating object centuries before British astronomer Edmond Halley gave it his name. According to new research involving Professor Simon Portegies Zwart, an English monk named Eilmer of Malmesbury appears to have recognized that the same…

People moved back into the British Isles around 15,200 years ago after the last major ice sheet began retreating, according to new research. That timeline is nearly 500 years earlier than earlier estimates suggested. The return of humans appears to have happened alongside a sharp increase in summer temperatures in…

Quantum entanglement is one of the strangest features of the quantum world. It describes a situation in which particles such as photons are so deeply linked that their properties cannot be fully understood one by one. Instead, the system has to be treated as a whole. That idea sharply conflicts…

Quantum computers and other advanced quantum technologies rely on specialized quantum materials that behave in unusual ways under the right conditions. In some cases, scientists can even create entirely new quantum properties by carefully changing a material’s structure. One striking example involves stacking sheets of graphene and twisting them into…

Scientists have identified surprisingly high levels of a little-known silicone pollutant in the atmosphere, raising new questions about possible risks to human health and the climate. The chemicals, known as methylsiloxanes, are commonly used in cosmetics, industrial products, transportation, and household items. Researchers found these compounds across a wide range…

Cacti are famous for growing slowly, but scientists have discovered that these desert plants are actually evolving at an impressive pace. New research shows that cacti are remarkably quick at forming entirely new species, revealing that deserts are far more dynamic than they may seem. For decades, biologists believed that…

The way people speak during ordinary conversations could offer valuable insight into brain health, according to new research from Baycrest, the University of Toronto, and York University. Scientists found that subtle speech characteristics, including pauses, filler words such as (‘uh,’ ‘um’), and difficulty retrieving words, are closely connected to executive…

Researchers at UBC Okanagan have uncovered the process plants use to create mitraphylline, a rare natural compound that has attracted attention for its possible cancer fighting properties. Mitraphylline belongs to a unique class of plant chemicals known as spirooxindole alkaloids. These molecules are recognized for their unusual twisted ring structures…

Researchers at the University of Maryland, Baltimore County (UMBC) have uncovered a crucial step that enteroviruses use to reproduce inside human cells.
