  1. ✨🔬 For a long time we knew #gold stayed shiny because it resisted #oxygen.

    Researchers at #Tulane University recently mapped the #physics behind this trait, and they found that surface #atoms on the metal rearrange themselves into a hexagonal structure that blocks #oxygen molecules from reacting.

  6. The earliest known #eukaryotes, the ancestors of all complex #life on Earth, lived in oxygenated, shallow marine environments nearly 1.7 billion years ago.

    The earliest eukaryotes for which we have #fossils lived in predominantly near-shore, oxygenated, benthic (on the seafloor) settings.

    This implies that the availability of #oxygen was dictating eukaryote #evolution from its early stages.

  11. made from dust for first time
    says it has developed reactor that can release breathable air from lunar soil
    Half of Moon dust — thin layer of rock that blankets lunar surface — is oxygen, but bound to metals such as iron and titanium.
    Blue Origin said it would need to generate around one megawatt of power to drive reactors. It envisages each lunar settlement would have an array of nearby solar panels, generating the power needed for one reactor.

  16. Appreciation for Cyanobacteria (and the humble species of the Nostoc genus)

    “It is certainly no exaggeration to say that we owe our existence in present form to cyanobacteria.” - Kartik Aiyer, PhD, University of Aarhus

    Behind the Shady Hollow Community Center in southwest Austin, Texas is a concrete slab. It may be related to a water treatment facility that was decommissioned a couple decades ago. During dry weather, one can find at one end of it dark patches of crunchy stuff that most persons would probably think is leaf litter or unidentifiable crud. But, when it rains, runoff water puddles at that end of the slab and the crunchy black stuff quickly becomes dark-green icky glop when it rehydrates. Look closely. It is a species of a cyanobacteria of the Nostoc genus. Some sources indicate it can survive 100 years in the dehydrated state. Cyanobacteria are believed to have evolved on Earth about 3.5 billion years ago and the Nostoc species about 600 million years ago. I take a deep breath, feel the effects of oxygen in my lungs, and appreciate the indispensable contribution that humble cyanobacteria made to my very existence. I have included photos that show the Nostoc from a distance and up close to reveal its photosynthetic chlorophyll.

  17. 🌲 IA Positiva: El Guardián que no parpadea
    ¿Y si los árboles pudieran avisarnos antes del fuego? No es una pregunta teórica, es una infraestructura que ¡Ya está operativa!

    Mientras dormimos, hay una inteligencia que no parpadea. Hoy mismo, en diversas zonas de alto riesgo de California y Europa, redes neuronales entrenadas en visión computacional monitorizan millones de hectáreas a través de cámaras térmicas y satélites.

    Lo disruptivo no es solo que "vean" el humo.

    Lo que tengo bajo control operacional son los datos de respuesta: **0,02 segundos**. Ese es el tiempo que tarda el sistema en distinguir entre una simple nube de polvo, el vapor de la mañana o una columna de fuego incipiente. Es tecnología salvando el aire que respiramos y el hogar de miles de especies antes de que la catástrofe sea imparable.

    Esto es la IA Positiva: no es un algoritmo frío diseñado para manipular tu atención o venderte publicidad. Es un escudo invisible que protege nuestros pulmones y optimiza la labor de los bomberos forestales, dándoles la ventaja táctica del primer segundo.

  23. Explanation for why we don't see two-foot-long #dragonflies anymore fails
    For decades, we thought that any dragonflies the size of hawks needed highly oxygenated air to survive because #insect breathing systems are less efficient than those of mammals, birds, or reptiles. As atmospheric #oxygen levels dropped, there wasn’t enough to support giant bugs anymore. “It’s a simple, elegant explanation,” said Edward Snelling, a professor of veterinary science. “But it’s wrong.”
