Children. Adults. Lies.
'If you don't behave, I'll call the police,' is a lie that parents might use to get their young children to behave. Parents' lies elicit compliance in the short term, but a new psychology study suggests that they are associated with detrimental effects when the child becomes an adult. (1) At the end, the truth…

Chaos. Numbers. Simulations.
Digital computers use numbers based on flawed representations of real numbers, which may lead to inaccuracies when simulating the motion of molecules, weather systems and fluids, find scientists. The study, published today in Advanced Theory and Simulations, shows that digital computers cannot reliably reproduce the behaviour of 'chaotic systems' which are widespread. This fundamental limitation…

AI. Universe. Logos.
Researchers have successfully created a model of the Universe using artificial intelligence, reports a new study. Researchers seek to understand our Universe by making model predictions to match observations. Historically, they have been able to model simple or highly simplified physical systems, jokingly dubbed the "spherical cows," with pencils and paper. Later, the arrival of…

Quantum… time? Quantum… cosmos?!
An international group of physicists led by Stevens Institute of Technology, University of Vienna and University of Queensland reveal the quantum properties of time, whereby the flow of time doesn't observe a straight arrow forward, but one where cause and effect can co-exist both in the forward and backward direction. To show this scenario, researchers…

Longevity. Xenon 124. Universe.
Theory predicts the isotope's radioactive decay has a half-life that surpasses the age of the universe "by many orders of magnitude," but no evidence of the process has appeared until now. An international team of physicists that includes three Rice University researchers - assistant professor Christopher Tunnell, visiting scientist Junji Naganoma and assistant research professor…
