Annulated sea snakes do have genes to see colour Annulated sea snakes, a venomous species found in the oceans of Australia and Asia, can see colour, debunking assumptions of colorblindness after surviving the last 110 million years in the ocean. Researchers used genome sequencing to find four intact copies of the opsin gene SWS1 &#8212 […]

pair-density-wave Scientists have revealed a new phase of matter in candidate topological superconductors that could have significant consequences for condensed matter physics and for the field of quantum computing and spintronics. Researchers at the Macroscopic Quantum Matter Group at Cornell University have discovered and visualized a crystalline yet superconducting state in a new and unusual […]

Earth’s inner core is textured, not smooth The Earth’s solid inner core is textured with ripples in the “fabric” that are more pronounced deeper into the core. Researchers examined seismic data from 2,455 earthquakes and found that the pattern of texture may mean Earth’s core endured a period of rapid growth before slowly hardening. Full […]

amorphous Scientists have dedicated their efforts to studying topological materials, focusing on the shape, or topology, of their electronic structures. These materials exhibit unique properties that have the potential to be harnessed for next-generation devices, despite their invisible nature in real space. Initially, it was believed that only crystalline materials, characterized by highly ordered atoms […]

Study upends idea that men hunted while women gathered The popular belief that early hunter-gatherer societies were organized around sex roles with men hunting and women gathering is incorrect, according to an analysis of data from academic papers focusing on 63 hunter-gatherer societies from across the world. The new research shows that 79% of communities […]

A novel computer memory design has been created by researchers, offering significant enhancements in performance while simultaneously addressing the pressing need to minimize energy consumption in internet and communications technologies. Projections suggest that these technologies could account for nearly one-third of the world’s electricity consumption within the next decade. A team of researchers has devised […]

Stronger earthquakes after cosmic radiation Cosmic radiation touching the Earth’s surface may lead to stronger earthquakes. Using data from the Cosmic Ray Extremely Distributed Observatory, scientists found a link between cosmic radiation and seismic activity that may be due to disruptions in the flow of matter in Earth’s core and magnetosphere. Full Story: Space Air […]

According to a recent study , humans have displaced a significant volume of water from the ground and relocated it, resulting in an Earth shift of approximately 80 centimetres (31.5 inches) eastward solely between 1993 and 2010. According to prior climate models, researchers had initially estimated that humans extracted around 2,150 gigatons of groundwater between […]

New theory of how Earth formed Scientists have found evidence that the Earth was created from a rapid landslide in less than 5 million years rather than a gradual series of celestial collisions, revising the longstanding theory of how Earth-like planets form in the galaxy. “With this new planet formation mechanism, the chance of having […]
