We reflect other people’s emotions through an ingrained, unconscious process. According to the facial feedback hypothesis, seeing a happy or angry face would make us contract or relax the appropriate face muscles to emulate that expression and better identify and experience the associated emotion. Since botox impairs some facial muscles from contracting in response to […]
HIP 99770 b is the first exoplanet detected through a pioneering approach that combines direct imaging with astrometry, the precise measurements of a star’s motion in the sky. This innovative method holds great promise for enhancing the efficiency of exoplanet searches, bringing us closer to the long-awaited discovery of an Earth-like twin in the vast […]
Evidence suggests that cyberbullying is more widespread among adolescents and young adults than among older people. This type of violence done intentionally using digital devices represents a wide range of online behaviors, such as: name-calling, online impersonation, solicitation for sex, sending coercive text messages, spreading online rumors, inserting offensive comments or isolation for example, being […]
Scientists use AI to sharpen first black hole image Scientists have used artificial intelligence to refine the first image of a black hole taken in 2019. The picture reveals a skinnier doughnut-shaped ring and darker center than the original image. Full Story: The Associated Press Volcanic eruptions led to 2 ancient extinctions Carnivores died in […]
Recent studies have revealed that the bending of light around massive galaxies is significantly smaller relative to theoretical expectations. This finding, the so-called lensing is low problem, has been interpreted as a breakdown of our cosmological model. Now, a team of scientists has found that the mismatch between theory and observations is actually caused by […]
nets One of the most interesting aspects of Joseph Sneed’s structuralist view of science is the one I mentioned in passing in my last entry: the fact that a scientific theory must not be understood as a mere combination or conjunction of different propositions (its “axioms”, plus the indefinite number of assertions they make about […]
Scientists ran a comprehensive analysis of data from collisions of heavy ions (actually, nuclei of atoms) to determine which factors most influence fluctuations in the flow of particles . They found that the conditions that are established just as the ions collide have the greatest impact. These conditions are related to the size of the […]
Semantic Author: Juan F. Trillo, PhD in Linguistics and Philosophy (U. Autónoma de Madrid), PhD in Literary Studies (U. Complutense de Madrid). Among the many features that differentiate us from other animals, one of the most striking is our ability to communicate. No other species has developed such an elaborate and effective language for exchanging […]
Tiger personality may be correlated with health Surveys of caretakers for 248 Siberian tigers at two fenced wildlife sanctuaries in China suggest that tigers have distinct personalities. Nearly 40% of the tigers’ behaviours fell into the “majesty” category, described as confident, competitive, and ambitious, or the “steadiness” category, reflecting obedience, tolerance, and gentleness. Those demonstrating […]
Quantum hair: The solution to the Hawking paradox? Researchers claim to have solved the Hawking paradox, or the conflict between quantum mechanics and the idea that black holes destroy all information about the stars that served as their creators. They suggest the radiation around black holes, also known as quantum hair, can hold onto information […]
