We ask whether bilingualism aids cognitive control over the inadvertent guidance of visual attention from working memory and from bottom-up cueing. We compare highly-proficient Catalan-Spanish bilinguals with Spanish monolinguals in three visual search conditions. In the working memory (WM) condition, attention was driven in a top-down fashion by irrelevant objects held in WM. In the Identify c...

We have recently criticised the natural pH gradient hypothesis which purports to explain how the difference in pH between fluid issuing from ancient alkali vents and the more acidic Hadean ocean could have driven molecular machines that catalyse reactions that are useful in prebiotic and autotrophic chemistry. In this article, we temporarily suspend our earlier criticism while we consider diffi...

Ultrahot disintegrating exoplanets have been detected with tails trailing behind and/or shooting ahead of them. These are believed to be made dust that formed out the supersonic escaping flow emanated from permanent day side. Conserving angular momentum, this day-side escape flux would lead planet in orbit. In order explain observation, radiation pressure, a repulsive force pushing away host st...

In this essay, we will take a wonderful ride on dark bubble with strings attached, which carries our universe out of the swampland and makes it realizable in landscape string theory. To find way to landscape, make use apparently hostile corners their instabilities.

Abstract Efforts to promote equitable public policy with algorithms appear be fundamentally constrained by the “impossibility of fairness” (an incompatibility between mathematical definitions fairness). This technical limitation raises a central question about algorithmic fairness: How can computer scientists and policymakers support reforms algorithms? In this article, I argue that promoting j...

We propose a simple model for the behaviour of longterm investors on a stock market, consisting of three particles, which represent the current price of the stock and the opinion of the buyers, respectively sellers, about the right trading price. As time evolves, both groups of traders update their opinions with respect to the current price. The update speed is controled by a parameter γ, the p...
