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......
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......
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......
The International Space Station will begin a gradual descent from orbit in 2028 before making a controlled plunge into the ocean in 2030, according to Roscosmos chief Dmitry Bakanov. The timeline confirms plans long discussed between Russia and NASA as the two agencies prepare to retire the aging orbital......
A new astronomical instrument under construction in the mountains of Chile is set to become the largest lens based telescope array ever built. Known as MOTHRA, the Modular Optical Telephoto Hyperspectral Robotic Array will combine 1,140 Canon telephoto lenses to observe extremely faint structures in......
A new generation of artificial intelligence tools is transforming biomedical research, enabling scientists to analyze genetic regulation, decode protein structures, and design drug compounds in a fraction of the time previously required. Recent studies show that machine learning systems can compress......
Eon Systems, a startup based in San Francisco, has introduced what it describes as the first full brain emulation of a fruit fly controlling a physically simulated body, producing several natural behaviors without machine learning training. The announcement, made on March 6, marks a significant step......
Astronomers using the Atacama Large Millimeter Submillimeter Array have detected unusually high levels of methanol in the interstellar comet 3I/ATLAS, revealing a chemical composition rarely seen in comets formed within our solar system. The findings, reported by the National Radio Astronomy Observatory......
