Less than a decade ago, there were about 2,000 operational satellites orbiting Earth. Today there are more than 15,000. Millions more are planned.
Phys.org ResearchRead article →Weather provided ideal conditions for enhanced ozone depletion
NASARead article →NASA’s Inspiration Tour spread the excitement of space exploration and aeronautical innovation by connecting the public, industry, and academia with the people, technologies, and organizations that drive American leadership in space. At nearly every stop across the country, NASA Space Grant has brought students into the heart of the action. In Iowa, NASA Administrator Jared […]
NASARead article →NASA successfully demonstrated technology designed to help spacecraft autonomously navigate to safe landing sites on the Moon and on other planets. An Alta-X drone equipped with the agency’s Safe and Precise Landing – Integrated Capabilities Evolution (SPLICE) guidance, navigation, and control payload completed simulated lunar descent and landing maneuvers Aug. 27. The flight took place […]
NASARead article →Researchers from the Aerospace Information Research Institute of the Chinese Academy of Sciences (AIRCAS) used satellite images collected across the growing season to map shrub cover in the grasslands of Inner Mongolia, China. By tracking seasonal differences in growth, they were able to distinguish shrub patches from dense grass, which can look similar in a single image.
Phys.org ResearchRead article →Even the world's most powerful telescopes have their blind spots. Although NASA's James Webb Space Telescope (JWST) can peer billions of years into the past, it still struggles to photograph planets orbiting nearby stars. Stars shine with such extraordinary brightness that their glare overwhelms nearby planets' faint glow.
Phys.org ResearchRead article →English, German, Dutch and the Scandinavian languages are all members of the Germanic language group, spoken by hundreds of millions of people today. But where did these languages come from?
Phys.org ResearchRead article →Research led by a University of Wollongong (UOW) Ph.D. candidate may have solved one of Earth's most perplexing geological mysteries: What caused the Great Unconformity?
Phys.org ResearchRead article →Children's developmental readiness in kindergarten can predict their math achievement as late as ninth grade, according to research from the University of Toronto's Ontario Institute for Studies in Education (OISE).
Phys.org ResearchRead article →Comprehensive genetic analysis has shed new light on the spread of an invasive, bloodsucking fly, which poses a devastating threat to the iconic Darwin's finches of the Galápagos Islands.
Phys.org ResearchRead article →An estimated 6 billion liters (1.6 billion gallons) of untreated sewage is discharged daily into the Ganges River Basin, home to 650 million people. Combined with seasonal monsoon flooding, the sewage and other pollutants, including agricultural runoff and industrial waste, create a major threat to public health.
Phys.org ResearchRead article →So far, observations by instruments including the James Webb Space Telescope have revealed the presence of surprisingly massive black holes in the early universe. Even less than a billion years after the Big Bang, some of these bodies already weighed billions of times the mass of the sun, and to date, astronomers are unclear as to how they could have grown so large so quickly.
Phys.org ResearchRead article →This photo released on Nov. 2, 2026, showcases NGC 4449, a dwarf irregular. Researchers using NASA’s Hubble Space Telescope studied 37 nearby dwarf galaxies — small galaxies containing a few thousand to hundreds of millions of stars — including NGC 4449 and found that much of the oxygen they expected to see is missing. Read […]
NASARead article →By injecting “thoughts” directly into large language models, researchers are trying to map out AI’s capacity for introspection. The post New Research Tests Whether AI Models Know Their Own Thoughts first appeared on Quanta Magazine
Quanta MagazineRead article →For six decades, wildlife researchers have faced a persistent challenge: to attach a tracking device to study a wild animal, they first have to catch it. Now, a new approach developed at the Norwegian University of Life Sciences (NMBU) allows GPS collars to be deployed autonomously on free-roaming terrestrial wildlife.
Phys.org ResearchRead article →Instructors and students have significantly different perceptions of how much generative artificial intelligence (AI) is being used in university studies, according to new research from The University of Manchester and Spain's Universidad del Pais Vasco/Euskal Herriko Unibertsitatea.
Phys.org ResearchRead article →Electron spin is a quantum property that makes electrons behave like tiny magnets. It can influence how electrons interact with each other and how chemical reactions take place. But what does this have to do with producing fertilizers, making cleaner fuels or improving energy technologies?
Phys.org ResearchRead article →A team led by Vojtěch Brlík from Charles University in Czechia and the University of Guelph in Canada analyzed data from more than 2,300 birds tracked using miniature devices to find out how closely linked individual stages of the migratory birds' annual cycle are.
Phys.org ResearchRead article →Human feet are much stiffer than those of other primates, which means they limit midfoot bending during walking. The evolutionary reasons for this are not entirely clear. One idea is that the features that stiffen the foot evolved to make upright walking less effortful.
Phys.org ResearchRead article →Experts from Amgueddfa Cymru and Cardiff University have used cutting-edge CT scanning technology to unlock a centuries-old combination lock recovered from one of Wales' most remarkable maritime discoveries.
Phys.org ResearchRead article →As the Mediterranean Sea continues to warm, it may become more favorable for some tropical tuna species. However, warmer waters do not necessarily provide all the environmental conditions these highly migratory fish need.
Phys.org ResearchRead article →The mangroves of Biscayne Bay have been getting help from an unlikely neighbor—the seagrass meadows just offshore. Dead seagrass blades and seaweed drift loose until the tide carries them into the mangroves, where they pile up, rot slowly and then become part of the ground.
Phys.org ResearchRead article →In recent weeks, people across Australia have found fluttering bogong moths (Agrotis infusa) in their homes, cars and even bedrooms. These insects have embarked on their annual migration from breeding grounds across southern Australia to the cool caves of the Australian Alps.
Phys.org ResearchRead article →Scientists have discovered a compound that transforms a natural muscle-repair protein into a more powerful version dubbed "Super HGF," more than doubling its ability to bind to a key receptor while protecting it from age-related chemical damage. The breakthrough, supported by early mouse experiments, could eventually help combat muscle loss and preserve strength as people age.
