Photochemical effects of Mars‐like UV irradiation on carboxylic acids in carbonaceous chondrites and expectations for abiotic background organics on Mars

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an

Diagnosing Merely Verbal Disputes: A Case Study on Personal Identity

open access: yesMetaphilosophy, EarlyView.
Abstract Merely verbal disputes have attracted considerable attention in metaphilosophy. Yet the critical task of discussing workable diagnostic methods for determining which disputes are merely verbal has been largely neglected, and detailed case studies of philosophical debates are rare. This paper addresses both of these gaps.

Detection and Characterisation of Transient Phenomena in Astronomical Images

open access: yes
Short-duration optical transients – point-like brightenings appearing and disappearing on timescales of seconds or less – represent a poorly understood class of astronomical phenomena. Their detection is complicated by the growing population of artificial objects in Earth orbit, atmospheric variability, and the difficulty of distinguishing genuine ...

Nature's Complexity Alive: Farewell to Several Unificatory Cosmological Arguments for Monism

open access: yesNoûs, EarlyView.
ABSTRACT Throughout history, numerous thinkers have claimed that monism—in the form of priority monism, existence monism, monotheistic monism, or versions that posit an extra‐cosmic ultimate being—theoretically surpasses pluralism, above all by positing a unified universe.
