In a bit of a dark mood today. maybe it’s the weather, maybe it’s the long stretch towards better weather and an end to the rain that I’m looking forward to, who knows, but I just fancied pulling together some creativity to brighten up the sparks inside my head.
The shot was made in autumn in the Lake District. It was our last day there of a short break and I took this opportunity of wandering around in a forest just behind a kids play farm that my daughter and wife went to. I had strict instructions not to disappear for too long, because ‘surprisingly’ I have a tendency to do that when the conditions play ball, and we had a long journey back home to tend with. Anyway I found this patch of silver birch trees that in the evening light kind of sparked my interest. I really wanted to play with composition and attempt to work an angle out of the kayos. I will let you be the judge of my success…
Oh if any of you haven’t seen my new website yet, please do head off to jasontheaker.com and let me know your thoughts and you can now book workshops there. I have a few places coming up in Whitby this February that I would be more than happy to help you spark your own neurons!
Geothermal areas of Iceland are absolutely breathtaking. There´s a lot of them and they are all different, so exploring these geothermal areas are one of the most exciting things you can do in Iceland. Very often, somewhere in the vicinity of these areas you will find a geothermal power plant, that converts this natural heat into energy for us to consume. An amazing project has been running since 2007, called CarbFix. Essentially, it involves technique of binding carbon dioxide gas as a mineral in local basalt rock in a fraction of the time. Carbon dioxide gas emitted from the power station is injected into water and then pumped deep down into basaltic rocks. Carbonated water is acidic. The more carbon you can pack into water, the more acidic the fluid will become. Carbonated water burns the rock underground forcing it to release elements such as calcium, magnesium and iron. In time, these elements will combine with the dissolved CO2 and form carbonates filling up the empty space in the basaltic rock underground. The carbonates are stable for thousands of years and can thus be considered permanently stored. The timescale of this process initially surprised the scientists as it was determined that 95% of the injected CO2 mineralizes within two years, much faster than previously thought. So far they have managed to inject back into the rocks nearly 65,500 metric tonnes of CO2.

Sheltering from the rain under the Neuron Pod at Queen Mary University of London.
"Centre of the Cell’s Neuron Pod is a striking 23-metre long and 10-metre high free-standing structure, located at Queen Mary University of London’s Whitechapel campus.
Neuron Pod is designed by the late Professor Will Alsop OBE RA at aLL Design, creator of STEM Pod and the surrounding Blizard Institute, which has won numerous design awards. Its design is inspired by images of a nerve cell, following on from the four pods inside the building that were inspired by other cells or molecules."

I was passing by storefront window and loved how the branches framed the mannequin's eye and branched out into her head like the dendrites of neurons in the brain. And how it seemed her hair glowed with her thoughts.

Lovely family walk this morning on the Monsal Trail. Lots of scooting, piggy back rides and talk of poo. Rileys favourite song subject at the moment.
I've long admired these moss covered branches. I love how their forms are so strikingly similar to that of the inner workings of the brain, lightning and the blood vessels which run around our bodies. Crazy.

When muscles work out, they help neurons to grow, a new study shows. The findings suggest that exercise's biochemical and physical effects could help heal nerves.

There’s no doubt that exercise does a body good. Regular activity not only strengthens muscles but can bolster our bones, blood vessels, and immune system.
Now, MIT engineers have found that exercise can also have benefits at the level of individual neurons. They observed that when muscles contract during exercise, they release a soup of biochemical signals called myokines. In the presence of these muscle-generated signals, neurons grew four times farther compared to neurons that were not exposed to myokines. These cellular-level experiments suggest that exercise can have a significant biochemical effect on nerve growth.
Surprisingly, the researchers also found that neurons respond not only to the biochemical signals of exercise but also to its physical impacts. The team observed that when neurons are repeatedly pulled back and forth, similarly to how muscles contract and expand during exercise, the neurons grow just as much as when they are exposed to a muscle’s myokines.
While previous studies have indicated a potential biochemical link between muscle activity and nerve growth, this study is the first to show that physical effects can be just as important, the researchers say. The results, which are published today in the journal Advanced Healthcare Materials, shed light on the connection between muscles and nerves during exercise, and could inform exercise-related therapies for repairing damaged and deteriorating nerves.
“Now that we know this muscle-nerve crosstalk exists, it can be useful for treating things like nerve injury, where communication between nerve and muscle is cut off,” says Ritu Raman, the Eugene Bell Career Development Assistant Professor of Mechanical Engineering at MIT. “Maybe if we stimulate the muscle, we could encourage the nerve to heal, and restore mobility to those who have lost it due to traumatic injury or neurodegenerative diseases.”
Raman is the senior author of the new study, which includes Angel Bu, Ferdows Afghah, Nicolas Castro, Maheera Bawa, Sonika Kohli, Karina Shah, and Brandon Rios of MIT’s Department of Mechanical Engineering, and Vincent Butty of MIT’s Koch Institute for Integrative Cancer Research.
Muscle talk
In 2023, Raman and her colleagues reported that they could restore mobility in mice that had experienced a traumatic muscle injury, by first implanting muscle tissue at the site of injury, then exercising the new tissue by stimulating it repeatedly with light. Over time, they found that the exercised graft helped mice to regain their motor function, reaching activity levels comparable to those of healthy mice.
When the researchers analyzed the graft itself, it appeared that regular exercise stimulated the grafted muscle to produce certain biochemical signals that are known to promote nerve and blood vessel growth.
“That was interesting because we always think that nerves control muscle, but we don’t think of muscles talking back to nerves,” Raman says. “So, we started to think stimulating muscle was encouraging nerve growth. And people replied that maybe that’s the case, but there’s hundreds of other cell types in an animal, and it’s really hard to prove that the nerve is growing more because of the muscle, rather than the immune system or something else playing a role.”
In their new study, the team set out to determine whether exercising muscles has any direct effect on how nerves grow, by focusing solely on muscle and nerve tissue. The researchers grew mouse muscle cells into long fibers that then fused to form a small sheet of mature muscle tissue about the size of a quarter.
The team genetically modified the muscle to contract in response to light. With this modification, the team could flash a light repeatedly, causing the muscle to squeeze in response, in a way that mimicked the act of exercise. Raman previously developed a novel gel mat on which to grow and exercise muscle tissue. The gel’s properties are such that it can support muscle tissue and prevent it from peeling away as the researchers stimulated the muscle to exercise.
The team then collected samples of the surrounding solution in which the muscle tissue was exercised, thinking that the solution should hold myokines, including growth factors, RNA, and a mix of other proteins.
“I would think of myokines as a biochemical soup of things that muscles secrete, some of which could be good for nerves and others that might have nothing to do with nerves,” Raman says. “Muscles are pretty much always secreting myokines, but when you exercise them, they make more.”
“Exercise as medicine”
The team transferred the myokine solution to a separate dish containing motor neurons — nerves found in the spinal cord that control muscles involved in voluntary movement. The researchers grew the neurons from stem cells derived from mice. As with the muscle tissue, the neurons were grown on a similar gel mat. After the neurons were exposed to the myokine mixture, the team observed that they quickly began to grow, four times faster than neurons that did not receive the biochemical solution.

“They grow much farther and faster, and the effect is pretty immediate,” Raman notes.
For a closer look at how neurons changed in response to the exercise-induced myokines, the team ran a genetic analysis, extracting RNA from the neurons to see whether the myokines induced any change in the expression of certain neuronal genes.
“We saw that many of the genes up-regulated in the exercise-stimulated neurons was not only related to neuron growth, but also neuron maturation, how well they talk to muscles and other nerves, and how mature the axons are,” Raman says. “Exercise seems to impact not just neuron growth but also how mature and well-functioning they are.”
The results suggest that biochemical effects of exercise can promote neuron growth. Then the group wondered: Could exercise’s purely physical impacts have a similar benefit?
“Neurons are physically attached to muscles, so they are also stretching and moving with the muscle,” Raman says. “We also wanted to see, even in the absence of biochemical cues from muscle, could we stretch the neurons back and forth, mimicking the mechanical forces (of exercise), and could that have an impact on growth as well?”
To answer this, the researchers grew a different set of motor neurons on a gel mat that they embedded with tiny magnets. They then used an external magnet to jiggle the mat — and the neurons — back and forth. In this way, they “exercised” the neurons, for 30 minutes a day. To their surprise, they found that this mechanical exercise stimulated the neurons to grow just as much as the myokine-induced neurons, growing significantly farther than neurons that received no form of exercise.
“That’s a good sign because it tells us both biochemical and physical effects of exercise are equally important,” Raman says.
Now that the group has shown that exercising muscle can promote nerve growth at the cellular level, they plan to study how targeted muscle stimulation can be used to grow and heal damaged nerves, and restore mobility for people who are living with a neurodegenerative disease such as ALS.
“This is just our first step toward understanding and controlling exercise as medicine,” Raman says.

Whilst experimenting with moving black fibre optics away from the camera (in a similar way to my blade tunnels), I ended up with very different results with each image. This was my favourite, being reminiscent of a bundle of nerve fibres, or MRI Diffusion Tensor Imaging. LPB Black Fiber Optic, connected via 2 LPB Universal Connectors to a Concentrate C5 RGB LED Light Unit. The C5 was on White mode - due to the seperate RGB LEDs being adjacent to the input end of the fibres, this results in a colourful range of primary and mixed colours. f/8, 2secs, ISO100.

An idea flowers in the garden of neurons
...and one is already thinking about another one, of course.
Able to go outside after 3 months and realised how amazing the nature is. Quite usual has become unique as every moment is new and different.
holaaaaaaaaaa storditones,
stasera la a lunga ci sta proprio tutta, mi rimetto a scrivere dopo giorni di incredibile fermo biologico del neurone.
Mi riaccendo la sigaretta e vi vorrei raccontare un pò di cazzetti miei come si dice dalle mie parti.
E' vero che in solitudine il cervelletto macina e oggi da solo lo sono stato per molto tempo, tutto il giorno praticamente solo con me stesso a leggere le pagine di una storia che non sento più mia ma che non ho voglia di abbandonare.
Periodo di verifiche e testa bassa a laurà, senza sosta, di sogni che viaggiano come treni e treni che se ne stanno fermi come mummie, circondato da cadaveri puzzolenti e amebe in cerca di identità, è dura cari storditones riuscire ancora oggi ad avere un credo, uno qualsiasi non mi metto mica a fare lo schifiltoso, ma mi basterebbe avere davanti un qualcosa che renda meno indifferente tutta la nostra attività quotidiana.
Una volta si diceva a gran voce: "Dio è morto!";
poi si è passato al "Marx è morto!";
ora mi sento di dover prendere in prestito la famosa frase di W. Allen che diceva:
"e io non mi sento troppo bene!"
Si, non mi sento bene preso per il culo da una società che non ha piu' l'uomo al centro del proprio progetto, che misura tutto con lo sterco del Demonio (grandioso chi coniò questa frase per indicare il Denaro), che non ha piu' rispetto per il lavoro ma solo per il saper fottere e comandare.
Certo so bene che è un prodotto di un lungo processo che ci portiamo avanti da anni se non da secoli, ma se permettete mi rode un pò sapere che le prossime generazioni dovranno vedersela con il baratro della solitudine e con la consapevolezza della sopravvivenza, perchè a questo si è arrivati, non si vive piu' si sopravvive, e non mi venite a dire che non è così, perchè di lamentele in giro ne sento a bizzeffe!
Forse ci provano a narcotizzarci con le grandi promesse di un mondo migliore, ma non è così si sta cadendo sempre piu' in basso, e sapete una cosa?
Ci hanno fatto credere che il lavoro nobilita l'uomo e hanno riempito le nostre case di scritturali con l'orologio in mano a scandire le ore per uscire dall'ufficio, nessuno sa piu' fare, provate a cercare un manovale, un idraulico, un agricoltore, non ci sono più, o meglio non ci sono più italiani disposti a farsi venire i calli sulle mani per portare a casa uno stipendio!
"Ma io ho studiato" direte giustamente voi, e si...avete studiato, ma col vostro diploma vi siete scavati la tomba della scrivania con le vostre mani, avete barattato i calli sulle mani con i calli sotto il culo, avete ceduto alle ferie scontate dal CRAL aziendale rinunciando ad una quotidianità creativa e sicuramente piu' stimolante, col risultato che ce l'abbiamo tutti davanti agli occhi:
una classe media arida pronta a prostituirsi per una fetta di mortadella in piu' a fine mese e con maestranze sempre piu' carenti.
Non credo duri tanto questa situazione, il vaso è colmo e non tutti possono accedere alla tastiera della produttività, anche perchè il mercato è saturo e i licenziamenti all'ordine del giorno, quindi ritorniamo al discorso iniziale:
Dio è morto e Marx pure, se io mi sento poco bene vado lo stesso a lavorare....nel mio mondo lavoro da Dio.....e non mi paga nemmeno la malattia..
hola storditones.....

Neurons are the building block of a nervous system. They are responsible for transmitting signals through out are bodies. I think trees are very similar. Trees create food for us and animals. They give us oxygen which is a must for are eco system to survive. They communicate in different ways but more or less it’s similar in many aspects.

Para empezar, siento mucho escribir en castellano, pero es que la neurona no me da para escribir en inglés ahora xD
He estado inactiva durante muchísisisimo tiempo y me siento muy culpable, sobre todo porque hace un tiempo, a finales de Enero, me fui a visitar a una cosa dulce y algodonosa llamada Ikaychín! Y tengo muchas muchas fotos por subir aquí y a mi flickr de no-muñecas del viaje tan lleno de recuerdos chachis. Lo siento mucho, la verdad, pero en cuanto volví no paré de hacer cosas y la rutina de la Universidad me absorve totalmente.... (para que digan que en Bellas Artes no hacemos nada xD) Intentaré tener las más importantes subidas ya este fin de semana ^__^
Así que, en primer lugar, ésta foto del Sebastian tan sexy es para su papi, que me acogió en su casa y me tuvo que aguantar durante una semana entera xD Lo pasé estupendamente, la verdad, algún día ya volveré, pero en veranitu te toca a ti acercarte para el norte (a ver surfistas... cofcof) >333
Por otra parte, una cierta cosa cuquinosa y chachi a la vez de kawaiiosa ha cumplido años hace poquito, y no he tenido tiempo de enviarle nada ni de dedicarle una foto ¬¬ *cabezazos contra la pared*
Esa personita es Ichi, mi gatufi favorita <3
Ichinosa mía, que sepas que tu regalín aún está en proceso, espero poder enviártelo enseguidita para que lo veas y disfrutes! Tengo ganas de mandártelo ya ^^
y por supuesto FELIZ CUMPLEAÑOS atrasados, cuquitufi, esta foto también te la dedico a ti, que se lo poco que te gusta Sebas-chan encima con esos ojitos rojos penetrantes que te atraviesan hasta el alma *__*
Ensherio, espero que te guste!
Así que, os mando un beso a los dos, corasonsuelos míos! <3 Ojalá volvamos a coincidir los tres para que el Universo entero colapse con todo el amor que desprendemos <3 <3 <3
Mwwwah! ^3^~~~~ <3

The Neuron Pod is a new science education centre in Whitechapel and a spectacular example of London's modern architecture.
Though you'd be forgiven for thinking it's a funky hedgehog, this 10 metre high, 23 metre long structure designed by aLL Design replicates a nerve cell and “comes alive” at night as it is illuminated with vibrant colour.
Over the past five months I've been visiting London periodically to shoot for my next book for Amberley Publishing called "London: A Modern City in Photographs". More details and pre-orders should be available in a few weeks. In the meantime, signed copies of my first book "Wales in Photographs" are available on my website www.mathewbrowne.co.uk/product/wales-in-photographs-signe...
