How close can a rocky planet be to a star, and still sustain water and life? Where is the edge of habitability? A recently discovered exoplanet may be key to solving that mystery, providing important insights about conditions at the inner edge of a star’s habitable zone and why Earth and Venus developed so differently […]
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 […]

Researchers have made significant progress in understanding the fundamental microscopic mechanisms that can be used to customize materials for heat insulation. This breakthrough represents a significant step forward in the continuous endeavour to understand heat transport, improve energy efficiency and promote sustainability. Heat transport plays a vital role in numerous scientific and industrial fields, including […]
Brain changes in astronauts Astronauts on space missions lasting six months or more have enlarged cerebral ventricles in the brain, according to a study of 30 astronauts. Researchers found that most ventricle expansion occurs during the first six months in space, but slows down after a year, and the astronauts’ brains fully recovered after three […]
C-H bond The emission of methane, a highly potent greenhouse gas, is escalating due to livestock farming and the ongoing thawing of permafrost. Converting methane and longer alkanes into more benign and valuable chemicals presents an opportunity to mitigate these hazards while providing a vast resource for the chemical industry. Nevertheless, the conversion of methane […]
Climate paradox of slashing emissions While cutting greenhouse gas emissions is necessary for reducing global warming in the long term, it may also lead to rapidly rising temperatures in the short term. R esearchers studying the emissions reduction during the pandemic show that while air pollution decreased, a lower concentration of aerosols led to a […]
Electrifying long-haul cargo-carrying trucks was deemed financially unviable. However, recent findings from researchers at Chalmers University of Technology demonstrate that operating electric heavy goods vehicles can be more cost-effective than using diesel. The shift from fossil fuel-powered to electric vehicle fleets has primarily been noticeable in lighter vehicles like private cars and delivery vans. However […]
Volcanoes, meteorites may be tied to life’s start Meteorites and volcanoes could have produced iron particles that served as a catalyst for creating life forms on Earth. Scientists conducted experiments using metallic particles from meteorites and ash from Sicily’s Mount Etna to see how iron may have helped convert carbon dioxide and hydrogen into hydrocarbons […]
