speleologists first noticed an unusual plume of vapor emerging from the limestone surface, hinting at a concealed water source beneath. This observation guided the team down a shaft that plunged more than 328 feet, where they encountered a vigorous...

they push aside surrounding material, allowing their radiation to carve bright pathways through the nebula. A prominent source of this glow is the binary system R Coronae Australis. The two components orbit each other over a period of roughly 43–47...

off northern Baja California, Mexico. The signal, catalogued as BW43, showed a clear acoustic signature but its biological source remained unknown, leaving the source animal hidden beneath the surface. In 2024 a research team from the U.S. Naval...

practice. Model Predicts Health Costs Outpace Caloric Gains The simulation shows that human flesh can provide a viable source of calories only under a narrow set of circumstances: the consumed individuals must be dead, the act must replace the energy...

million years ago, a timeline that aligns with earlier suggestions that Denisovans inherited DNA from a much older hominin source. TRACE maps ghost ancestry across the human genome, revealing hidden archaic DNA beyond Neanderthals and Denisovans...

rivers” that shuttle moisture through the atmosphere above South America, shaping precipitation patterns far from their source. Unlike the fleeting atmospheric rivers that dominate headlines, these aerial currents are persistent pathways formed by a...

one of the toughest orbital regimes—very low Earth orbit (VLEO), where the thin remnants of the atmosphere are both a source of drag and, potentially, a source of propellant. Testing a Thruster That “Breathes” Earth’s Upper Atmosphere ABEP technology...

of an ongoing galaxy merger. Chandra’s X-ray observations provided the critical proof, detecting two separate, high-energy sources that perfectly aligned with the galaxy’s dual nuclei. Estimates place the mass of these black holes at approximately 19.5...

fused bones—a signature trait of modern birds—confirmed the tail belonged to a primitive theropod. “We can be sure of the source because the vertebrae are not fused into a rod or pygostyle as in modern birds and their closest relatives,” noted co-author...

offset by the CO2 previously sequestered from the air. The environmental viability of this cycle remains contingent on the source of the electricity used, as a grid reliant on fossil fuels would negate the carbon-neutral claims. An internal view of the...

et al, Nature Astronomy) Unmasking the Faint Galaxy Host Distinguishing the host galaxy from the brilliant central point source has been a primary challenge for astronomers. At the infrared wavelengths captured by the JWST, the central object—likely an...

an ultrasound of the Earth’s interior. A schematic showing how different seismic waves travel through Earth, from the source of an earthquake (star) to a seismic station at the surface (triangle). Waves get deflected near the core-mantle boundary (CMB)....

V-shaped aluminum component, the devices transform thermal energy into mechanical movement. When exposed to an infrared source, the elastomer surface contracts, inducing a rotation that the V-shaped frame resists. This tension causes the structure to...

unexpected signal propagation or interference. Because these layers reside within the ionosphere, they are a primary source of error for satellite navigation and long-range communication systems. Understanding their true nature is vital for refining the...
