My kind of video-game! I wrote a proposal to create a video game like this back in 1989 when I was working at the Good Samaratin Hospital when I arrived in L.A. determined to improve science education for the disadvantaged. A colleague of mine at the hospital was a computer programmer and during our breaks we sketched ...out a game that would teach immunology. But the technology was too primitive and we gave up. Now the Federation of American Scientists has gone and done it! Bravo!!! I hope everybody plays through this awesome edutainment piece!

You must navigate a nanobot through a 3D environment of blood vessels and connective tissue in an attempt to save an ailing patient by retraining her non-functional immune cells. Along the way, you will learn about the biological processes that enable macrophages and neutrophils – white blood cells ..
"Bioaugmentation—taking existing beneficial bacteria, culturing them, and
then adding more of them back into a biological system (not too
different from eating probiotic
yogurt for its purported beneficial effects on the human gut)—is the
key to restoring amphibian populations". You know I love this stuff - exploring mutualisms I believe is not only the key to saving amphibians, but our civilization too... :)

If you are into phosphourous and nitrogen recovery from urine wastes, and are looking for a way to produce your own urease to hydrolize the urea, this website shows a simple way of extracting it from soy beans.

Anna Lorenc from the Volvox project explains the importance of the enzyme urease and presents a protocol to demonstrate urease activity in the classroom.
Make your own struvite fertilizer from your urine waste stream (great for users of Ecolet separation toilets like we saw happening in urban Kigali, Rwanda) using urease derived from jack beans, and MgCl. This provides a simple form of nitrogen and phosphorous recovery to radically improve agriculture. (Actually, you ca...n skip the urease if you let the urine sit in a bacterially active chamber for a while to hydrolize the urea into ammonia). Liquid Magnesium Chloride is sold in Europe and America as a de-icer solution but it is also a food additive (a type of table salt) sold in Japan as Nigari and is an ingredient in baby formula milk. It is derived from seawater when the sodium chloride is removed. Should be available everywhere.

When you watch this excellent German narrated, English subtitled French documentary, there are scenes at the beginning (part 1) and particularly at the end (of part 2) that prove that Jean was compressing his own biogas, putting it in a steel tank mounted on the roof of his truck, and driving around Southern France's... rural roads with it. So why is this considered difficult or overly expensive to do? Can we find out what Jean was using for compression?

http://www.permacultureplanet.com/ - Jean Pain (1930 - 1981) was a French innovator who developed a compost based bioenergy system that produced 100% of his energy needs.

The great French forester Jean Pain (who sadly passed on in 1981 in his early 50s) proved for permaculture that forest brush (which must be cleared regularly to prevent massively damaging and expensive fires) could be used to produce enough heat (aerobically) and biogas (anaerobically) to completely heat and power his ...massive Southern France home and his truck. An 80 m3 pile of chipped brush (40 tons of wood waste) saturated with 20 tons of water produced continuous heat and gas for 18 months before needing replacement. Savings were 4000 liters of oil equivalent from hot water and 5000 liters of oil equivalent from biogas. Set aflame and burned the same amount of wood material would have yielded only 3000 liters of oil equivalent. The heating of the home alone through compost heat produced 1/5 more thermal energy than people get from burning the wood, and instead of leaving smoke and ash, the composting of the wood yielded him a nitrogen rich

"Function stacking!". You gotta love it. Compare this with the 3 to 4 days of labor it took for us to make solar hot water heaters (not bad in itself) - but this system, which gave reliable hot showers 24/7 (even at cold dawn) to 20 interns a day for 2 months from one pile of leaves and detritus took a mere hour and a... half of labor to build. They are running 100 feet of 1/2 inch coiled poly pipe in a lasagna like stack. 9 such piles would give reliable hot water all year, even in the winter. And people are deforesting for fuelwood why?

You can feel the quickening -- the world is pregnant with great ideas to get us off of oil and bring health to our peoples (again, as in the 70s), and once you join the ranks of the tinkerers, the assemblers, the boot-strap pullers and the bricolage artistes, you find this is all rather simple really. And you are still using fossil fuels why?

Hola, amigo! My dear Maya friend, que tal? How are things in Guatemala? You asked me a while back what I thought of the 2012 predictions that so many people of European heritage are panicking about and I'm sorry I've taken so long to answer. This article from NASA Astronomer David Morrison explains v...ery nicely why the "doomsday" predictions are not just silly but dangerous to real actions intended to keep our planet livable. They are sad distractions that are giving people who are doing serious damage to our ecosystems the ability to keep the public thinking about ridiculous threats instead of focusing on fighting the real threats - deforestation, fossil fuel use, air and water pollution, overfishing etc. As Morrison points out, the Maya calendar, like all calendars, is great for recording the past and for predicting cyclical events by finding patterns in their periodicity (like seasonal changes). The destruction of our planet is not cyclical since it h...

The destruction of our planet is not cyclical since it has never happened before, thus it can not be predicted by any calendars, or any science known to us or to the marvelous Maya.

Hola Thomas, gracias por acordarte de nosotros, como estás, te cuento que efectivamente el calendario Maya termina el 21 de diciembre del 2012, los aj kijes y 0 sacerdotes Mayas deconocen el significado de la no continuación del conteo calendárico, hay teorías de teorías y no precisamente mayas o adoptadas por los mayas, sobre la destrucción del mundo lo que personalmente siento y creo es que deberá de empezar una nueva era con un nuevo calendario y con una nueva actitud del ser humano hacia su casa la tierra, solo si y solo sí, cambia la actitud del hombre sobrevivrá a la destrucción labrada por la misma humanidad, no hace falta ser muy sabio para entender que los cambios ya iniciaron , pero como siempre el hombre torciendo los caminos a este paso solo nos espera la autodestrucción y no hace falta que vengan cuerpos y entes celestiales a destruinos si no queremos cambiar, la filosofía de los antiguos Kiches, segun los relatos del Popol Vuh cuando se despidieron los cuatro primeros hombres inciadores de este pueblo dejaron un mensaje que analizado debiera de orientarnos al respecto y Dijeron "NOSOTROS YA NOS VAMOS, IREMOS A VER EL LUGAR DE DONDE HEMOS VENIDO, LES ROGAMOS QUE MIREN PRIMERO SU CASA, MIREN PRIMERO SU PATRIA, NO NOS OLVIDEN, NO NOS PIERDAN " el hombrre actual ha perdido las lecciones de su pasado, no entiende su presente y le tiene pavor al futuro, por eso estamos al borde de la locura, contestame y si hace favor escribime en español, me cuesta mucho el ingles y te contaré mas de o que pasa aqui en Guatemala
