There’s a lot of enthusiasm for intermittent fasting — a term that can encompass everything from skipping a meal each day to fasting a few days a week.
Quantum Leaps, Long Assumed to Be Instantaneous, Take Time
When quantum mechanics was first developed a century ago as a theory for understanding the atomic-scale world, one of its key concepts was so radical, bold and counter-intuitive that it passed into popular language: the “quantum leap.” Purists might object that the common habit of applying this term to a big change misses the point that jumps between two quantum states are typically tiny, which is precisely why they weren’t noticed sooner. But the real point is that they’re sudden. So sudden, in fact, that many of the pioneers of quantum mechanics assumed they were instantaneous.
Partícula X17: qué es la quinta fuerza que dicen haber descubierto científicos húngaros
Desde hace décadas la comunidad científica ha reconocido la existencia de cuatro interacciones fundamentales que controlan el Universo: el electromagnetismo, la gravedad, la fuerza nuclear débil y la nuclear fuerte.
Pero ahora un estudio húngaro asegura haber observado una quinta fuerza de la naturaleza, un hecho que podría revolucionar nuestra comprensión del funcionamiento del mundo.
El análisis fue llevado a cabo por científicos del Instituto de Investigación Nuclear de la Academia de Ciencias de Hungría (Atomki), quienes estudiaron el comportamiento de un átomo de helio excitado y cómo emite luz a medida que se descompone.
Se dice que un átomo se encuentra en estado excitado cuando alguno de sus electrones, gozando de una mayor energía, salta de la órbita que ocupaba en estado fundamental a una órbita exterior, más alejada del núcleo.
Here’s What Happens To Your Body When You Overthink
All that excessive obsessing and rumination totally takes a toll on you physically and mentally.
This widespread rumination and over-obsessing has become somewhat of an epidemic. One study from the University of Michigan found that 73% of adults between the ages of 25 and 35 overthink, as do 52% of 45- to 55-year-olds.
Interestingly, research has found that many overthinkers believe they’re actually doing themselves a favor by cycling through their thoughts. But the truth of the matter is that overthinking is a dangerous game that can have a lot of negative consequences on our well-being.
A Link Between Dark Matter and Antimatter Could Be Why the Universe Exists
In a new experiment, scientists probed a theory that suggests a weird interaction between two of the biggest mysteries in physics could be why our universe exists in the first place.
O novo teto solar da Tesla será tão barato quanto um telhado de telha
Segundo o CEO da Tesla , Elon Musk, as novas telhas solares da empresa serão acessíveis para o proprietário médio. Musk diz que elas terão aproximadamente o mesmo custo que o telhado de telha típico.
Universal Quantum Phenomenon Found in Strange Metals
Experiments suggest that exotic superconducting materials share a “strange metal” state characterized by a quantum speed limit that somehow acts as a fundamental organizing principle.
Physicist suggests ‘quantum foam’ may explain away huge cosmic energy
Steven Carlip, a physicist at the University of California, has come up with a theory to explain why empty space seems to be filled with a huge amount of energy—it may be hidden by effects that are canceling it out at the Planck scale. He has published a paper describing his new theory in the journal Physical Review Letters.
Conventional theory suggests that spacetime should be filled with a huge amount of energy—perhaps as much as 10120 more than seemingly exists. Over the years, many theorists have suggested ideas on why this may be—most have tried the obvious approach, trying to figure out a way to make the energy go away. But none have been successful. In this new effort, Carlip suggests that maybe all that energy really is there, but it does not have any ties to the expansion of the universe because its effects are being canceled out by something at the Planck scale.
High-fat diets affect your brain, not just your physical appearance
Much research has pointed to how an unhealthy diet correlates to obesity, but has not explored how diet can bring about neurological changes in the brain. A recent Yale study has discovered that high-fat diets contribute to irregularities in the hypothalamus region of the brain, which regulates body weight homeostasis and metabolism.
Cientistas desenvolvem combustível líquido que pode armazenar a energia do sol por até 18 anos
Cientistas na Suécia desenvolveram um fluido especializado, chamado de combustível solar térmico, que pode armazenar energia do sol por mais de uma década.
