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 […]
Light emission (fluorescence or phosphorescence) in organic molecules, in the vast majority of cases, proceeds from the lowest energy excited state irrespective of the excitation energy used. This is known as the Kasha’s rule, which states that most of the molecules are emissive from the lowest energy, same (ground state) spin multiplicity, S1 excited state […]
wildfires Author: Aaron Bell, Researcher, PhD Candidate, Biology, University of Saskatchewan With the summer solstice and first official day of summer on June 21, hot and dry conditions have already given rise to a very active fire season across Canada. The smoke from these fires has drifted great distances, disrupting activities and causing a nuisance […]
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 […]
It is a warning that keeps repeating once and again: the behavior of artificial intelligence will soon be indistinguishable from that of human beings. A frightening and inevitable moment that is drawing ever closer. A recent paper available on arXiv [/footnote] Daniel Jannai, Amos Meron, Barak Lenz, Yoav Levine, Yoav Shoham (2023) Human or not? […]
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 […]
nuclear star cluster This image from the NASA/ESA/CSA James Webb Space Telescope shows the heart of M74 (or NGC 628), otherwise known as the Phantom Galaxy. Webb’s sharp vision has revealed delicate filaments of gas and dust in the grandiose spiral arms which wind outwards from the centre of this image. A lack of gas […]
Cancers are the second leading cause of death in the world, after cardiovascular diseases. Their seriousness lies in their diversity – some can be effectively treated with surgery, chemotherapy and radiotherapy, while others respond poorly or not at all. Improving the treatment of these diseases is therefore a major challenge. For several years, the development […]
