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…
The growing popularity of GLP-1 medications such as Ozempic, Wegovy, and Rybelsus has largely been driven by their ability to help people lose weight, improve blood sugar control, and reduce the risk of cardiovascular disease. Now, researchers have uncovered another possible benefit. A new clinical trial suggests that semaglutide, the…
A remarkable fossil at Montana State University’s Museum of the Rockies is offering scientists an unusually detailed glimpse into how Tyrannosaurus may have attacked its prey.
