Electromagnetism is a property of spacetime itself, study finds
WEBJul 23, 2021 · In particular, our research shows how electromagnetism is an inherent property of spacetime itself. In a way, spacetime itself is therefore the aether. Electric and magnetic fields represent certain local tensions or twists in the spacetime fabric. Our research shows that the Lagrangian of electrodynamics is just the …
Swimming boosts brain health, but scientists don't yet know why
WEBJul 27, 2021 · But a growing body of research suggests that swimming might provide a unique boost to brain health. Regular swimming has been shown to improve memory, cognitive function, immune response and mood. Swimming may also help repair damage from stress and forge new neural connections in the brain. But scientists are still trying to unravel how and ...
Can consciousness be explained by quantum physics? Research is …
WEBJul 20, 2021 · Research is closer to finding out. One of the most important open questions in science is how our consciousness is established. In the 1990s, long before winning the 2020 Nobel Prize in Physics for his prediction of black holes, physicist Roger Penrose teamed up with anaesthesiologist Stuart Hameroff to propose an …
WEBA circular pee-conomy. Doing this is quite easy: you just fill a urine dryer with an alkalising agent, connect it to your toilet, pee as usual and the urine is converted into dried fertilizer. A smart design could even make the dryer fit below the toilet so it doesn't take up a lot of bathroom space. While electricity would be needed for ...
Warp drives: Physicists give chances of faster-than-light space …
WEBCompression and expansion. Physicists' current understanding of spacetime comes from Albert Einstein's theory of General Relativity. General Relativity states that space and time are fused and that nothing can travel faster than the speed of light. General relativity also describes how mass and energy warp spacetime—hefty objects like stars ...
Societal transformation: A role for second-order cognitive science?
WEBFeb 4, 2021 · Second-order science, in contrast, is explicitly normative and reflexive. The scientist is understood as part of the experiment, the aim is to affect change, and the effort is value-driven. With this distinction in mind, the title of the series is "Science-Driven Societal Transformation." Cognitive science plays a critical role here, because ...
New mechanism driving cortical gyrification and hydrocephalus …
WEBDec 12, 2019 · Cortical gyrification, or the stereotypic folding pattern in the forebrain, is implicated in the development of human cognition. During evolution, the mammalian brain went through several transitions between smooth and folded brains. What mechanism underlies the extent and pattern of folds is yet to be deciphered. Moreover, defects with brain folding are very commonly found in ...

A way to turn urine into solid fertilizer that could make farming …
WEBNov 9, 2020 · We estimate that it would cost just US$5 (£4.20) to supply an average family of four with a year's supply of alkalising agent. The output from the dryer is a solid fertilizer containing 10% nitrogen, 1% phosphorus and 4% potassium—a similar combination to blended mineral fertilizers.. The first flush toilet, invented by Alexander Cummings in 1775, revolutionized sanitation.
