A violent collision in the main asteroid belt may have triggered a prolonged wave of impacts across the inner solar system about 800 million years ago, according to a study led by the Southwest Research Institute. The researchers propose that the breakup of the parent object that formed the Eulalia…
Scientists have discovered that one of the most extreme volcanic events in Earth’s history did more than build a massive underwater plateau. It also altered the structure and chemistry of the oceanic plate beneath it. A research team led by Lecturer Azusa Shito of Okayama University of Science, working with…
A 12 week intermittent fasting program may help people maintain weight loss for at least a year after the structured intervention ends, according to research involving the University of Granada (UGR). Published in Clinical Nutrition, the study followed 99 adults who were overweight or obese. Half of the participants were…
New observations from the James Webb Space Telescope, or JWST, are giving astronomers their clearest look yet at how supermassive black holes obtain the gas they need to grow. The images reveal long strands of gas linking a galaxy’s hot outer atmosphere to a rapidly rotating disk surrounding its central…
A Mediterranean-style diet may influence aging through an unexpected biological pathway involving tiny proteins produced inside mitochondria, according to a new study led by researchers at the USC Leonard Davis School of Gerontology. Mitochondria are best known as the structures that generate energy inside cells, but scientists increasingly recognize that…
Terraforming is the process of reshaping a planet or moon so it can support humans and other Earth-like life. In theory, that means changing an alien world’s atmosphere, climate, and surface to more closely resemble Earth’s by adding oxygen, creating stable bodies of liquid water, and producing temperatures suitable for…
Every summer, lawns fill with colorful “silly sprinklers,” whose looping and twisting tubes send water spraying in unusual patterns. Their designs may look playful, but researchers have now used these backyard devices to investigate a serious and decades-old question in physics. The mystery is known as Feynman’s Sprinkler Problem. It…
Commonly used sweeteners can directly interfere with the growth of bacteria that help support a healthy gut, according to laboratory research from the University of Cambridge. The strongest effect appeared when researchers combined isosteviol, a sweetener used by the food and beverage industry, with the antidepressant duloxetine. Together, the two…
Some breakthroughs in physics come from brand new inventions. Others begin with a new theory. But many advances happen when researchers combine familiar technologies in an unexpected way and create something more powerful than the individual parts. That strategy could be especially valuable in the search for weakly interacting particles,…
Researchers at King’s College London have identified a promising new strategy for tackling Alzheimer’s disease by targeting several of the disease’s earliest biological changes at the same time. Their study found that KCL-286, an experimental drug originally developed for spinal cord injury that has already passed Phase 1 safety trials,…
Scientists have uncovered how a toxin produced by a common gut bacterium gains access to colon cells, solving a mystery that has puzzled researchers for more than 15 years. The discovery not only explains how the toxin begins damaging the colon, but also points to a possible new way to…
The U.S. Centers for Disease Control and Prevention (CDC) is working with state and federal health agencies to investigate several outbreaks of cyclosporiasis. Efforts to determine and confirm the sources of these outbreaks are still underway. A large outbreak of cyclosporiasis has been reported in at least four Midwestern states.…
Researchers at the City College of New York are charting a fast-growing area of quantum science centered on materials only a few atoms thick. In these systems, light, electric charge, and magnetism are closely connected rather than behaving independently. The work comes from physicist Vinod M. Menon’s Laboratory for Nano…
Imagine the year 2158. You’re pursuing a PhD in planetary volcanology at the University of Utopia Planitia on Mars, surviving on freeze dried ramen while searching for the perfect exoplanet to study. After finishing your research on Jupiter’s volcanic moon Io, you need a rocky world beyond our solar system…
People struggling with depression often continue to experience memory problems, poor concentration, and mental “brain fog” even after their mood improves. Now, researchers say an existing prescription drug approved to treat chronic constipation may also help improve those lingering cognitive symptoms. The findings, published in Psychological Medicine, come from an…
Brain cells continually pull material from the fluid around them, including nutrients, signaling molecules, and fragments of their own outer surfaces. This process, called endocytosis, supports learning, memory, and the routine maintenance of neurons. Penn State researchers have now identified a previously unrecognized structure that may control much of this…
A colorful pet gecko that is unusually prone to developing cancer could become an important new tool for researchers studying how tumors form and spread. Scientists say the animal’s naturally occurring cancers may offer valuable insights into why some species are highly vulnerable to the disease while others are remarkably…
The Black Sea, which lies between Europe and Asia and connects to the Mediterranean through a series of waterways, is known for its dark waters. But every spring and summer, it undergoes a remarkable transformation, with large areas turning a vivid turquoise. On June 22, 2026, NASA’s PACE (Plankton, Aerosol,…
Archaeologists working at the ancient Egyptian site of Oxyrhynchus have made a remarkable discovery: a papyrus containing a passage from Homer’s Iliad was found inside a Roman-era mummy dating back about 1,600 years. Researchers say it is the first known case in archaeological history in which a Greek literary text…
Humans have earned a reputation as “super-predators” because they hunt, trap, and fish on a scale unmatched by other predators. These activities can reshape animal behavior across entire landscapes. However, new research led by the Centre for Ecological Sciences, Indian Institute of Science (IISc), suggests that wildlife does not respond…
NASA has chosen 41 technology proposals from 37 American companies to help develop the capabilities needed for future missions to the Moon and Mars. The selections are part of the agency’s 2025 Announcement of Collaboration Opportunity (ACO), which is designed to accelerate innovations in areas such as space transportation, planetary…
Astronomers have directly confirmed four previously hidden white dwarf stars in nearby binary systems. Every system lies within 65 light-years of Earth, and one contains the ninth closest known white dwarf to the Sun. The discoveries were made by researchers at the University of Warwick and the University of Colorado…
People who regularly visit museums, theaters, concerts, and movie theaters may be doing more than enjoying themselves. A new study suggests these cultural activities are associated with a younger physiological age, meaning the body may function more like that of a younger person. The findings, published in the Journal of…
Scientists have uncovered why some amphibian populations rebound after being devastated by a deadly fungal disease that has wiped out frogs and toads around the world. The research, led by University College London (UCL), ZSL, and Imperial College London, found that the timing of an amphibian’s immune development plays a…
Archaeologists have uncovered crystals at numerous sites containing Homo remains, suggesting that early human relatives deliberately collected these unusual stones as far back as 780,000 years ago. What makes this behavior so intriguing is that the crystals were not used as tools, weapons, or jewelry. So why were they considered…
Researchers at King’s College London have uncovered an unexpected connection between chewing sugary gum after eating nitrate-rich vegetables and a temporary reduction in blood pressure. The findings suggest that, under specific conditions, sugary chewing gum can help the body make better use of dietary nitrate found in foods such as…
Could eating lots of chili peppers affect your cancer risk? Scientists have been debating that question for years, and the answer remains far from simple. While chili peppers contain compounds that have shown anti inflammatory and even anticancer effects in laboratory experiments, some human studies have linked very high consumption…
K2-18b has become one of the most closely watched exoplanets in recent years. The planet lies about 124 light years away in the constellation Leo and orbits within the habitable zone of a red dwarf star. Observations from the James Webb Space Telescope have revealed an atmosphere rich in carbon…
After nearly 40 years of research, scientists have uncovered evidence that challenges a long held assumption about forest soils. The world’s longest running soil warming experiment suggests that even carbon once considered stable can begin to break down as temperatures rise, releasing additional CO2 into the atmosphere. Jerry Melillo, a…
