Astronomers have identified the source of unusual X ray emissions from gamma Cassiopeiae, resolving a scientific mystery that has persisted for nearly five decades. Observations from the XRISM space telescope show that a hidden white dwarf companion is responsible for the high energy radiation, ending......
Astronomers have reconstructed the full 12 billion year history of a spiral galaxy for the first time, offering new insight into how galaxies form and evolve over cosmic time. The study, led by the Center for Astrophysics Harvard and Smithsonian and published in Nature Astronomy, focuses on the massive......
Tiny drones deployed inside a damaged reactor at Japan’s Fukushima Daiichi nuclear plant have captured the first clear images of the bottom of Unit 3’s pressure vessel, revealing a large hole in the thick steel structure and hanging masses believed to be melted nuclear fuel. The footage,......
Research in natural sciences in 2025 shows a clear move toward interdisciplinary work, with progress concentrated in biomimetic materials, artificial intelligence, ecological science, and laboratory automation. These trends reflect efforts to respond to climate pressures while improving the efficiency......
Scientists from EPFL and CSEM in Switzerland have developed a triple-junction perovskite-silicon solar cell with a certified efficiency of 30.02 percent, setting a new benchmark for this class of technology. The findings were published on March 16 in Nature. The new device surpasses the previous certified......
Astronomers using the James Webb Space Telescope have identified an exceptionally dense atmospheric haze surrounding the exoplanet Kepler-51d, blocking efforts to determine its chemical composition and origin, according to a study published in the Astronomical Journal. An international team led by researchers......
Scientists have identified all five canonical nucleobases, the molecular units that encode genetic information, in samples returned from the asteroid Ryugu. The findings, published on March 15 in Nature Astronomy, support the theory that carbon-rich asteroids delivered key chemical ingredients to early......
For the first time, researchers have been able to determine the precise age of Paleolithic cave paintings in the Dordogne region of southwestern France, offering new insights into prehistoric artistic practices. The discovery concerns artworks found in the cave of Font-de-Gaume, one of the most important......
Scientists at Yale University have discovered that HIV produces a circular RNA molecule that helps the virus activate its genes and replicate more efficiently. The finding reveals a previously unknown layer of HIV biology and could open new avenues for antiviral therapies. The study, published on March......
A team of mathematicians has demonstrated that a long-standing principle in differential geometry proposed more than 150 years ago is not universally valid. By constructing two distinct torus-shaped surfaces that share identical geometric measurements and curvature properties, the researchers showed......
Researchers at Stanford University have found that aging may unfold through sudden transitions rather than a steady, gradual decline. The findings come from an experiment that tracked nearly every movement of small fish throughout their lives and showed that early behavioral patterns can predict how......
An international team of scientists has identified about 2.3 million ancestral DNA sequences that function as hidden genetic instructions across the plant kingdom. Some of these regulatory elements have remained conserved for nearly 300 million years of evolution. The findings, published March 12 in......
Astronomers have reported several discoveries that deepen scientific understanding of some of the most extreme events in the universe, including the direct observation of a magnetar forming and new insights into how compact stellar remnants collide. For the first time, researchers have directly observed......
