Here is a problem that has been quietly gnawing at astronomers for decades.

The standard approach to detecting #life on other worlds involves scanning #exoplanet #atmospheres for #oxygen, #methane, and #ozone, whose presence is difficult to explain without #biology.

It's a clever idea, but it carries a hidden flaw. That entire shopping list was written by studying Earth. It is, inevitably, a search for life like us.

The list of ways that #chemistry alone can accidentally mimic these #biosignature gases is growing faster than the list of new ways to detect life.

Each new false positive scenario demands even more information about the #planet to rule it out, and there is a genuine question about whether that information can ever be gathered exhaustively.

But there is a solution.

#Assembly theory doesn't ask what #molecules are present in an #atmosphere. Instead, it asks how hard they were to make.

Every molecule can be assigned an assembly index, a minimum number of construction steps required to build it from basic #chemical building blocks.

Simple molecules are easy to assemble by chance, but truly complex ones, requiring many sequential steps, don't arise without something doing a great deal of deliberate selection.

That something would then be life itself.

Отладка STM32 программатором J-LINK по SWD

В разработке на микроконтроллерах широко распространены J-link программаторы-отладчики. Также доступно клиентское ПО для них Ozone . У J-link есть 20 пиновый разъём. На нем заложены пины для шины SWD и UART . SWD это - двухпроводной полудуплексный интерфейс для программирования микроконтроллеров. В этой заметке я расскажу как прошить микроконтроллер STM32 по SWD шине при помощи программатора J-link.

Long-term exposure to ambient air pollutants and female infertility risk: a population-based cohort study in Taiwan. [2025]
https://doi.org/10.1186/s12889-025-24213-x

This article reports that most air pollution components (SO2, PM2.5, NOX, etc.) are linked to higher infertility in women, however, a negative association was found with ozone [O3] exposure . I wonder if that is because O3 tends to form in sunlight and O3 exposure might correlate with sun exposure?

#infertility #fertility #AirPollution #sunlight #photobiomodulation #ozone

Fine particulate matter, or PM2.5, refers to particles less than 2.5 micrometers in diameter, small enough to penetrate deep into the #lungs & enter the #bloodstream. #Ozone is a #smog-causing gas that forms when nitrogen dioxide & volatile organic compounds are emitted from power plants, factories & vehicles & mix in the #air on hot, sunny days.

#CopterPortrait Meet Hopper¹, our second and bigger #multicopter with meteorological #PARASITE payload. This one can carry a lot more sensors, so we have more temperature and humidity measurements, some gas sensors (#CO2, #Ozone, #NO2) and most importantly #particles. The two chimneys at the sides are two inlets for particle measurements: one is dried with silica beads and the other just gets unchanged ambient air. You can read more about this in this² paper. While you're at it, you can have a look at our other publications on particles, e.g. this one³.

Of course, Hopper's PARASITE payload also runs ❄️ #NixOS.

Posadas 2025: Avivando la llama

Del 27 al 29 de junio de 2025, la localidad cordobesa de Posadas volvió a acoger uno de los eventos más esperados por la comunidad, la Posadas Party 2025. Organizado por los legendarios Batman Group y The Brothers, el encuentro reunió a programadores, artistas gráficos, músicos y aficionados de todos los rincones para disfrutar una vez más con pasión del AMIGA y la escena.

Durante el evento se celebraron competiciones en más de 14 categorías, que incluyeron gráficos, intros, música, demos y videojuegos. A diferencia de otras ediciones, esta entrega se caracterizó por una notable participación en formatos alternativos como Android, Windows, TIC-80 y hardware personalizado, demostrando que la escena está más viva que nunca.

Entre los títulos más aclamados destaca Ninjyations, de Soy, que se alzó con el primer puesto en la categoría de juegos homebrew. También brillaron creaciones como Xenomorph de Juande3050, SwitcherBoy de Tecniman, y The Last Door – Episodio 1, adaptación del clásico point & click llevada a cabo por Daniel Pontiveros.

En el terreno gráfico, magiA de Veritas y z3k y Who’s Afraid of Batman Group? de Zaac / Madwizards pusieron el listón muy alto tanto en OCS como en AGA.

En cuanto a la música, Estrayk, Jeenio, JosSs, Fireboy, Jesusito y ReSeT contribuyeron con composiciones que cruzaban estilos tan diversos como el acid jazz, la electrónica o el tracker clásico.

En la categoría Wild, el grupo Volumetric Illusions sorprendió con VI-SAT 01, una demo para hardware personalizado, mientras que inCubus Mundi (Android) y Calling my name (Windows) demostraron que el espíritu demoscener no entiende de plataformas.

El evento también contó con invitaciones destacadas producidas por Batman Group y Jesusito, ambas disponibles online como parte del archivo histórico del encuentro.

"The problem is that deploying massive constellations of low earth orbit (LEO) satellites that have a typical lifetime of 5 years can load up the mesosphere with the metal oxides upon their reentry, and there will be a lag of 20 or 30 years before gravity pulls these oxides down into the ozone layer which they can then severely degrade."

https://www.youtube.com/watch?v=vvcfVFCqMMY

"CO2 is responsible for around 55% of global warming to date. The other 45% comes from #SuperPollutants: #methane; black carbon; #fluorinated gases; #NitrousOxide; and tropospheric #ozone.

As well as being substantial contributors to global warming, super pollutants are a major threat to human health.

Hundreds of defunct #satellites plunge through Earth’s #atmosphere yearly, and the count is rising.

The dying satellites, it turns out, don’t just wink out into the ether. Each one leaves a bit of itself behind.

The satellites’ fiery death throes, along with a steep rise in the number of rocket launches, are adding a glut of ozone-destroying and climate-altering pollutants to the #stratosphere.

For instance, aluminum oxides are catalysts for #ozone depletion.

#Trees don’t like to breathe #wildfire smoke, either – and they’ll hold their breath to avoid it

Published: July 30, 2024

"When wildfire smoke travels long distances, the smoke cooks in sunlight and chemically changes.

"Mixing volatile organic compounds [#VOCs], nitrogen oxides and sunlight will make ground-level #ozone, which can cause breathing problems in humans. It can also damage plants by degrading the #leaf surface, oxidizing plant tissue and slowing #photosynthesis."

The ozone hole above Antarctica will keep opening up each spring for decades to come

"The ozone layer is a vital planetary boundary that protects all life on Earth from the sun’s damaging ultraviolet radiation.Ozone depletion is also linked with climate change, and there are other emerging issues which could affect ozone recovery. These include more frequent mega-wildfires due to climate change, emissions from rocket launches and more satellite debris burning up in the upper atmosphere. Recent research shows mega-wildfires such as the Australian bushfires of 2019 can contribute to ozone depletion."

When old satellites fall into Earth's atmosphere and burn up, they leave behind tiny particles of aluminum oxide,
🔸which eat away at Earth's protective ozone layer. 🔸
A new study finds that these oxides have 💥increased 8-fold between 2016 and 2022 💥
and will continue to accumulate as the number of low-Earth-orbit satellites skyrockets.

The 1987 Montreal Protocol successfully regulated ozone-damaging #CFCs to protect the #ozone layer,
shrinking the ozone #hole over Antarctica with recovery expected within fifty years.
But the unanticipated growth of #aluminumoxides may push pause on the ozone success story in decades to come.
Of the 8,100 objects in low Earth orbit, 6,000 are #Starlink satellites launched in the last few years.
Demand for global internet coverage is driving a rapid ramp up of launches of small communication satellite swarms.
#SpaceX is the frontrunner in this enterprise, with permission to launch another ⭐️ 12,000 Starlink satellites and as many as ⭐️42,000 planned.
#Amazon and other companies around the globe are also planning constellations ranging from 3,000 to 13,000 satellites, the authors of the study said.
Internet satellites in low Earth orbit are short-lived, at about five years.
Companies must then launch replacement satellites to maintain internet service, continuing a cycle of planned obsolescence and unplanned pollution.

Aluminum oxides spark chemical reactions that destroy stratospheric ozone, which protects Earth from harmful #UV radiation.
The oxides don't react chemically with ozone molecules, instead triggering destructive reactions between ozone and chlorine that deplete the ozone layer.
Because aluminum oxides are not consumed by these chemical reactions, they can continue to destroy molecule after molecule of ozone for decades as they drift down through the stratosphere.
https://phys.org/news/2024-06-satellite-megaconstellations-jeopardize-recovery-ozone.html

"This is more than a #climate problem. N₂O also depletes the #ozone layer, which protects humans from harmful solar radiation. And #nitrogen runoff from fields pollutes waterways, increasing harmful algal blooms and creating oxygen-depleted dead zones."
