Nunca pensó la roca que pudiera tener una piel tan suave... Stigonema crece sobre las rocas y va tejiendo un colchón infinitamente suave y mullido de fibras huecas que la aúpan hacia la luz y que al tacto parece aire. Tapiza así algunos recovecos en la cueva de un terciopelo liviano como un soplo, y es sobre la parte más alta de este manto fluido y aéreo, donde sus tallos crecen buscando cualquier destello de luz en ramitas de gelatina, que laten de vida en sus extremos.
Es casi magia comprobar como esta cianobacteria que hasta hace unos años fue considerada como un ser eucariota primitivo, es en realidad la cianobacteria (bacteria) de estructura más compleja que se conoce y que se desarrolla formando unas estructuras ramificadas que recuerdan a los tallos de las pequeñas plantas, que independizándose del agua, colonizaron la la Tierra y que a junto a ella, a pocos centímetros, fluyen las masas de gelatina violeta de Gloeobacter que representan a unos de los linajes más primitivos de estos seres y que nos transporta a los orígenes de la vida en la Tierra.
De este modo, el origen primigenio de la vida y su presente se unen aquí, dándose la mano, en el entorno de la Ares Station en un salto por el tiempo de más de tres mil millones de años en apenas tres centímetros de distancia, estrategias primitivas que han venido funcionando superando cataclismos y el paso de un tiempo casi infinito, junto a otras que entroncan con el relevo evolutivo que supuso el independizarse del agua y conquistar los continentes yermos para vivir.
Sobre esa caliza yerma, apenas regada por unas gotas y por un débil rayo de luz Stigonema crece exuberante en selvas densas formando filamentos multiseriados con varias células de ancho, que forman ramas laterales cuando las células se dividen perpendicularmente al eje principal del filamento. Y a medida que su cuerpo crece y avanza por un extremo, por el otro se va apagando, dejando la trama de su tapiz vano y aislando la parte viva de la inerte como en un viaje hacia el espacio.
El proyecto de astrobiología que se desarrolla en el entorno de la "Ares Station" de Astroland, busca conocer qué estrategias biológicas podrían ser efectivas para que la vida pueda desarrollarse más allá de la Tierra y diseñar protocolos y técnicas para hallarla, pero al mismo, también utilizar todo lo que nos enseñan estos seres minúsculos que viven en condiciones extremas formando parte de unos biofilms muy particulares, para mejorar la vida en nuestro planeta.
Muchas cianobacterias, para sobrevivir han diseñado un complejo arsenal de herramientas químicas que les ha permitido competir e impedir ser eliminadas por otros seres vivos que podrían ser sus depredadores y todavía este tesoro espera ser descubierto.
Stigonema, por ejemplo, sintetiza un péptido complejo de indudable interés médico y farmacológico, la estigonemapeptina, que inhibe la síntesis de elastasa, una enzima que interviene en la degradación de las fibras elásticas en las células tanto eucariotas como procariotas, Nostoc sintetiza compuestos antivirales...pero la mayor parte del potencial de estos organismos aún no se conoce, porque apenas se han investigado.
Sobre las húmedas calizas por las que se desliza silenciosa en la penumbra, Stigonema va pintando con su cuerpo las paredes, no es un hábitat muy propicio para la vida y por eso quizá Stigonema parece abrazarse a ella con la trama que forma su cuerpo acuoso de gelatina. La especie que mostramos aquí, y que se señala por vez primera para la Península Ibérica, muy probablemente corresponda a Stigonema informe, especie quizá cosmopolita y poco citada, que puede vivir tanto en la superficies rocosas sumergidas como sobre rocas húmedas.
La masa gelatinosa de Stigonema informe forma céspedes de filamentos que se enmarañan pintando la superficie de la cueva en masas de filamentos parduzcos, amarillentos o blanquecinos. Stigonema informe suele crecer a partir un filamento principal con ramas bien diferenciadas. Los filamentos principales pueden presentar hasta 4-6 filas de células, de 38-42 µm de ancho y ramas de 24.0-44.0µm de ancho y una vaina gruesa. Las células son de hemisféricas a redondeadas, a veces agrupadas formando "paquetes", 7.2-16.0µm de largo, 6.4-12.0 µm de ancho y con un contenido celular granulado, verde azulado.
En las muestras recogidas en la cueva solo los extremos de los filamentos parecen tener actividad y corresponden a los expuestos a la tenue luz que penetra desde la entrada. Observados al microscopio con epifluorescencia, las vainas mucilaginosas se muestran en color blanquecino y los cuerpos celulares vivos en color rojo, debido a la clorofila que contienen.
Los biofilms de la cueva de Arredondo, donde está emplazada la "Ares Station", la primera estación aeroespacial subterránea permanente, que recrea un ambiente análogo al de Marte, constituyen un magnífico muestrario para desarrollar protocolos de investigación astrobiológica que desde la agencia espacial Astroland se están llevando a cabo, y que abren nuevos caminos a otras investigaciones que se realicen a millones de kilómetros de distancia en los tubos volcánicos del Planeta Rojo
Las fotografías, tomadas en vivo a 200 y 400 aumentos con las técnicas de contraste de interferencia y epifluorescencia, proceden de unas muestra recogidas en el interior de la cueva del Escalón en Arredondo (Cantabria) el 14 de noviembre de 2020 en el marco del apasionante proyecto de investigación astrobiológica que Astroland está desarrollando para acercarnos a Marte con la ayuda y la compañía de amigos entrañables, Jesús Rocandio, @rocandiojesus, Iara Chapuis, @iarachapuis, Noelia Rojas y Miguel Catalán que hicieron de este día un regalo inolvidable, que nos encantaría volver a repetir pronto.
¡¡ Gracias !! ❤.

My friend Michael Naimark is exploring new ideas for virtual reality experiences, in collaboration with Google and other researchers. To discuss this work, we got together with two other colleagues, Steve Gano and Jim McKee -- with whom we worked at the Apple Multimedia Lab in the eighties, pushing the envelope on related questions.
We started with a tour of the historic Sentinel Building in North Beach, home of American Zoetrope -- where Francis Coppola worked on many cinematic masterpieces like The Godfather and Apocalypse Now. We checked out the underground screening room and sound mixing room where some of that work took place, then headed upstairs to Michael and Jim’s studios, for a wonderful conversation about the new VR frontier.
Michael and his colleagues are researching how people are represented in virtual reality. Their first experiment at Google’s “Big Chairs” Park led to some helpful guidelines on how to film people for VR, by using different camera angles and distances.
They’re also investigating ‘hyper-images’ that resemble a group of people, but that are shot at different times and composited together to create both ‘credible’ and ‘incredible’ pictures. To enable more experiments like these, Michael is developing ‘IMU VR’, a new type of camera that could make it easier for communities to tell their stories in VR. More on this later.
It was great to reconnect with my colleagues and brainstorm these ideas together. It felt like the good old days, and the creative juices were flowing all over again ...

I like to create imaginary worlds. I invent virtual simplified realities, probably the result of travel memories and past experiences. I choose the types of buildings, I place them on a fictitious ground, check the colors of the various parts, the lights, the elements of the landscape. And then I choose a point of view and portray this place of fantasy. The traditional landscape painting has to deal with the atmospheric variables, with the mutability of natural light. Here, on the contrary, not only everything is static, but I can change the various elements at will: add or remove pieces, move something, try the effects of shadows depending on the movement of the lights. But it is a small difference, and also the difference between "real" reality and virtual reality is now small: it has become part of our daily lives, changed our way of perceiving, and somehow has itself become real.

I've never met you, yet never doubt you
I can't forget you
I've thought you out, dear
I know your profile and I know the way you kiss
Just the thing I miss
On a night like this
If dreams are made of imagination
I'm not afraid of my own creation
With all my heart my heart is here for you to take
Why should I quake?
I'm not awake
Isn't it romantic?
Music in the night, a dream that can be heard.
Isn't it romantic?

Okay....I had so much fun!!! Have any of you ever done this virtual reality thing? It's so strange but fun!!!! LOL My oldest son's wife had her birthday party yesterday and we went to Ronan, MT. and did this at her plea!! You put these goggles on and go into these enormous situations and find things that are hidden....there are clues!! You really feel like the scene is real!!!!! Us grand folks even enjoyed it!!!! Aughhhh!! I got to fight a dragon!! 😮 Those are my 2 grandsons in front row...they're 13. It's suppose to be 66 this coming Wednesday!!! Yay!! Her parents are in this image.
