¿Cómo enviar mensajes a extraterrestres?
Chasqui, 2015 Durante más de treinta años, los humanos han utilizado la tecnología de radio para buscar evidencia de inteligencia extraterrestre -ETI-. Colectivamente, estos esfuerzos se conocen como SETI.

Mutual Detectability: A Targeted SETI Strategy That Avoids the SETI Paradox
The Astronomical Journal, 2020 Abstract As our ability to undertake searches for extraterrestrial intelligence (SETI) grows, so does interest in the controversial endeavor of messaging extraterrestrial intelligence (METI). METI proponents point to the SETI Paradox—if all civilizations refrain from METI then SETI is futile.

Finding Fireballs in Lightning: A Daily Pipeline to Find Meteors in Weather Satellite Data
Earth and Space ScienceWeather satellite data contains a wealth of information well beyond its application to meteorology. The GOES weather satellite Geostationary Lightning Mapper instruments detect millions of lightning strikes per day.

When Communication Enables Catastrophe: Nuclear Risk and the Short Lifetimes of Technological Civilizations: A Bayesian Scenario Analysis of Civilizational Survival and the Fermi Paradox. [PDF]
Risk AnalABSTRACT The Fermi paradox may partly reflect technological self‐destruction acting as a Great Filter during post‐industrial development. Because the empirical record consists of a single civilization observed over an eighty‐year nuclear age, the exercise reported here is best understood as a structured, historically anchored scenario analysis rather ...

Intestinal Lipoma as a Cause of Sigmoid Colo-Colic Intussusception in an Adult: A Case Report. [PDF]
Clin Case RepABSTRACT Adult intussusception is an uncommon and often unexpected diagnosis, typically driven by an underlying structural lesion. We report the case of a 43‐year‐old woman who presented with a month‐long constipation, five days of worsening intermittent abdominal pain associated with nausea, bilious vomiting, and anorexia.

Median Arcuate Ligament Syndrome: A Hidden Cause of Abdominal Pain. [PDF]
Clin Case RepABSTRACT Median arcuate ligament syndrome (MALS) is an uncommon condition where the median arcuate ligament compresses the celiac artery, leading to reduced blood flow. It commonly presents with upper abdominal pain after eating, unintentional weight loss, and an audible abdominal bruit.

SETI e a Grande História: Desafio e Extensão
Journal of Big History, 2020 SETI é um dos relevantes desafios ao arcabouço da Grande História, e que expande seus propósitos. A Grande História tem exercido impacto similar sobre a história mundial, da mesma forma que as histórias nacionais impactaram as histórias religiosas.

How Proton Incorporation Reshapes Lattice Dynamics In BaSnO<sub>3</sub>-Type Proton Conductors. [PDF]
Adv Sci (Weinh)Yttrium‐doped BaSnO3 exhibits isotope‐dependent changes in its low‐energy vibrational density of states upon hydration. Comparison of dry, H2O‐, and D2O‐treated samples re‐veals mass‐dependent phonon renormalization linked to proton dynamics near oxygen va‐cancies, providing experimental insight into hydrogen‐coupled lattice excitations in proton ...

A History of Cosmic Habitability
Journal of Big History, 2020 Our understanding of the universe is based on the big bang cosmological model, which describes an expanding universe whose development began 13.8 billion years ago from a hot, dense state.
