this is data data generated from an electrical grid from wires streets businesses. when you can harness data you can do things you couldn't do before. prepare for alternative energy sources celebrate the adoption of electric vehicles help prevent blackouts see the data from energy usage as it happens and you can do it to do in places like california and build a smarter energy system that's going to support a claim. hello and welcome to technology update the environment around us is one of staggering biological diversity somehow all held together into the big ten of our planet's ecosystem and while much of the natural world has been here for thousands of years we're just starting a one walk many of its secrets how exactly did all of this get here how do bio systems of all shapes and sizes interact and what's our influence on this process

as humans we learn from our ecosystem to both help it and perhaps help ourselves these are questions as old as time now getting a fresh look in the twenty first century the institute of bio physics of the siberian division of the russian academy of sciences is well placed for a new perspectives surrounded by some of the earth's most unique and unadulterated ecology and applying the lessons of physics to biological research. made them i can with the methods of mathematical modeling monitoring an experimental method of studying small isolated and care systems. sciences to assess the current trends prevalent in the biosphere. but we have evidence that any shifts in the ecosystem and not accidental a full under common law the law of preservation yet the young we can identify key fact is that influence any specific ecosystem and by manipulating them with able to

control the makeup of the system is one of the key areas for by a physicist. searching the cycles has become a question ecosystems. as these scientists know well this kind of research means getting where they're taking today's fine tuning technology to the water to find out about the conditions in creatures prevailing beneath its surface you might not get your kicks standing the sea or lakes for tiny plankton but they tell us what's happening in our aquatic systems now yesterday and what tomorrow may hold this team has developed a video laser detection instrument to make this work easier as the laser illuminates the critters to be counted in specific depths in the water column i got the chance to tag along on one of the team's trips to a unique siberian salt lake called shoot up from their base there they're taking measurements and collecting samples that might help us understand aquatic ecosystems worldwide. situated in the russian republic of. three hundred sixty

kilometers to the southwest of the institute in krasnoyarsk. we have now reached the needed level about fourteen minutes this where oxygen is replaced by hydrogen sulfide only specific species of bacteria are able to leave under such conditions. basically as a compact of the ancient biosphere out of. the first billion was no oxygen. and the water was saturated with carbon dioxide hydrogen sulfide would we do the impact analysis for various trying to is the key and then apply the trends to there was a habit to. do similar lakes elsewhere but. most of us saw in the underlying principles trends of the same.

in that a small even more peculiar body of water and another focus for the bio physicists study. half that of ocean water that can reach. for that reason it's home to a very very simple spectrum of biological diversity a short chain with tiny stations at the top. physical layers. to spend it in place leaving oxygen depleted. witness below the surface of. to study the make up of the each of the lakes fine layers the crescent team developed their own patented hydraulic sampler with the ability to collect specimens at intervals of just five centimeters.

this strange contraption helped us to discover the thick purple. unit is unique in terms of the predominance and sheer numbers of purple sulfur bacteria . just one lake in canada with such a massive population of these types of bacteria. can be attributed to specific conditions to help the species thrive. in the. physics institute's base camp after a day on the lakes we went inside the on site laboratory to make sense of what we pulled out from under water they see that what we find in the multicolored layers sucked out of should net are important for more than just the stablish. down there . from the lakes are almost like rings on a tree a detailed record of this isolated ecosystem over time and when these guys started connecting the dots things get even more interesting.

models are a real strong suit. help us do the retrospective analysis. to assess the climatic conditions including precipitation during a given historical period. perspective on when we envisage what will happen in case it gets wet or dry but this is what the salt lake study is all about. to find out exactly what's going on in our planet's vast ecosystem you need a lot of people to do a lot of trekking sometimes in virtually inaccessible regions thankfully we have the ability to get a bird's eye view. observing massive forest habitats like those cars. bringing the bread to siberia often means exploding aerial photography satellites are also being used to keep tabs on the big picture whether that's checking for fires illegal logging or just changes in natural biological patterns of course to get didio information about what's growing

or dying and why we still do much of our fact checking on foot. changes in our biosphere can be split into two categories natural and unnatural natural ones that come with the shift of the seasons these are the trends we have observed over a number of years it's crucial to know the overall amount of buying a result of the way that they are growing old to. exact distribution across the territory the status of crow the data collected from these combine methods offer something like micro pro and telescopic versions of our forests ecological situation and the results can also be used on a different scale down the street at the forestry institute tree specialists have noticed a troubling trend. amid the worsening environmental situation in russia's forces including signing period we're witnessing a decline in reproductivity it's a problem that's facing all coniferous tree species found in siberia that we've

introduced and he meant it to tackle it's a combination of a classical selection techniques an innovative. twin able to mass reproduction of improved genome and we sake cells of genetically improved tree. that is them on a nutrition substrate and put them into a peek inside the chief the embryonic tissues start growing in juicing the formation of cooled kalus a mass of undifferentiated cells beautiful this will be the breeding ground for the new cinematic embryo that is if we take the callous transfer it into another be kept here. and within a full to five weeks we get out of this massive cells. that you can see here in the petri dish this is when the vegetation stage begins we put these green embryo into another petri dish with a different substrate is

a thing that's where the new generation of trees will grow and three to four months of growth they are recognizable for example this is a genuine slight period launch you can plant it into soil any way you like. to do and that's exactly what the forestry institute is doing starting their genetically selected plants out in a deforested spot they set aside in the cross now street it's too soon to tell but they're hoping it's a model that can be expanded in applied across the wide reaches of siberia experimental methods of exploring launch ecosystems our planet is a unique object there's no alternative to experiment with and it's only piece by piece that we get a scientific p.h.l. of the ecosystem presents unique tools to integrate various data into a single possible scientists are also modeling the human body as an ecosystem and like the planet we inhabit it can't always be subjected to risky experiments

another group grown out of the bio physics institute wants to observe and test live animal organisms in a safe close setting starting with our constituent parts the key instrument. three m. . the. near this apparatus is ideal for the study of the various bio chemical reactions of a human organ. the message we use fall somewhere between research in vitro in a test tube and in vivo when the focus on the organs performing inside the body. of the. three m. is an artificial homeostasis device for maintaining organ. separated from their natural bio system cure the role of the lungs is played by an oxygenated regulating the flow of oxygen and carbon dioxide through the organ perfusion pumping acts like the organisms heart pushing the blood substitute through the isolated organ the tubes running to the organ from the pump to take oxygen rich blood from the heart

while the tubes that bring the fluid back from the organ are like our veins instruments on both the arterial and greenish sections allow researchers to monitor the blood substitutes consistency and the functioning of the order the machine also allows for additional solutions to be pumped into the system to alter the makeup of the fluid and if she were desired result. then check to the first and set a proper temperature and while it's working they can proceed to the operation if you don't mind assisting. our organ donor for research is a typical lab right here we're most interested in testing the animals liver it's a mirror of the process first human organ donor only we won't be putting the liver on ice as is still common in transplant practice the homeostatic could be a genuine lifesaver if it could be incorporated into this process because it

essentially tricks an organ into thinking it's in its natural bio system this liver will be kept alive in the machine almost exactly as if it were still filtering it's only as fluids. we extract the organic to study its physical and chemical capacity as the record so far has been five days the liver continued to perform its functions at virtually full tilt as long as it lives for at least twenty four hours it means we can study the organ as if it were inside the human body. is chosen here not simply because of the importance of liver transplants another area for interest in the study is pharmacology a field where despite organ is a focal point. as a key link in the chain of our metabolisms. detox and our systems deliver is always under scrutiny in. the homeostatic provides a closed proving ground to find out how different substances impact a liver function changes for better or for worse in the organs performances can be

observed in isolation since the machine holds other simulated body functions at a constant. then you know for course this is just the rats and there will definitely be more research and tests before the device can be used in medical practice we've been able to gather data on the elimination rate for some of the substances and observe the metabolic activity. the lab rats someone usual sea creatures are also waiting in our attempts to learn more about our own bodies in fact the seas are the richest resource we have seen bioluminescent organisms while many are tiny simple critters they're also bearers of precious photo proteins which could light the way an important medical research. one of the world's pharmaceutical giants they test millions of substances in the search for active ingredients to use in new medicines and so-called bioluminescent reporters make this process far easier fortunately they found

a formidable partner for developing this part of their project also at the bio physics institute in krasnoyarsk. in krasnoyarsk is the largest of its kind in the world today. it was a lucky coincidence for both parties. that's. just . his colleagues have kept the partnership by isolating and regenerating proteins they found in sea creatures from all over the world. exactly what's allowing the animals to illuminate the ocean they extract and focus on multiplying that protein. to then produce an essentially unlimited amount of the substance without having to go back for more trips having mastered this technique they pass it on to go back to what they do best in the waters for new bioluminescent animals

with new proteins with new properties. new chemical compounds. in pharmaceuticals. and then they all need to be tested for the potential targets. expresses the bioluminescent protein. allow for a rapid preliminary screening of potential chemical compounds. perspective. only ten to twenty will be picked for further analysis. there's. significantly speed up the. techniques are able to test some one thousand five hundred similar.

which means that within less than a minute or so you test one thousand five hundred new chemical compounds. technically advanced stages. under control of. diagnostics. says have the. method. disease or other substance in the patient's blood radioactive isotopes are combined with antibodies and injected into a sample of the patient. would then take the place of the released isotopes these can be measured and are equal to the level originally present in the sample. new method uses i believe a bioluminescent photo protein in place of the radio isotopes harvested from the marine hydroid. in the addition of calcium ions to generate light for measuring the presence of a given. protein is every bit as accurate but will be safe.

we've been able to modify the spectrum of bio luminescence. we now have one protein mutant. and another green which. we can conduct. by separating the spectrum with ordinary optical filters. two substances for example two hormones in. contemporary methods of molecular biology. to cultivate an almost unlimited amount of this photo protein in. the pursuit. no areas left in biotechnology that don't employ the potential of methods.

for. any field. can do without bioluminescence that could mean taking these markers beyond the borders of medical testing in pharmacology to service a smoke signal for virtually any effect we wish testing our air for pollutants the soil for which nutrients for our children. toys for toxins pick the right protein and wait for the light much of the time we're using the natural properties of biological systems to our advantage without even thinking about it like when microbes in the soil help break down our trash but that's only effective for refuse we know it's biodegradable and we're piling up ever more plastic it will pollute our planet for centuries consumption of plastics continues to skyrocket with estimated global use up to one hundred million tonnes each year meanwhile recycling rates remain low and the effectiveness of plastic recycling is highly debatable but innovations in bio plastics and a laboratory of kemah water traffic biosynthesis in krasnoyarsk might help us break the habit but. there are interesting and promising objects to by technological

study the chemical reaction of oxidising hydrogen produces a wide range of various compounds the line includes anything from the crystallized then the pastika polymers the two rubbery material such as allows to ms we can adjust and customize their characteristics for a specific industry specific furthermore it's even possible to set the exact time of by degradation which is a crucial achievement it's difficult to reach by practice proof. practice is been accumulated over the last two decades during which. has led russia in the field of bio plastics research. biopolymers that are the basis for any end product the first step is to facilitate the growth of more hydrogen oxidising bacteria then the task is to separate the polymer from the bacteria and test its purity. approach it is unique in that we're able to

use almost any industrial sources of language and like so cooled gas synthetic gas extracted during the processing of brown coal natural gas hydrolyzed lignin and even. hydrogen on. ising bacteria house is the best results for the level up to ninety percent. with that high polymer from the bacterial mix scientists continue to careful process of refining it it's a recurring cycle of reduction in precipitation requiring a lot of hands on in man hours and the. method makes sense in limited quantities for testing properties or small scale prototypes but the scale of potential applications for bioplastics is far bigger requiring production of an altogether more ambitious order. traffic biosynthesis team. setting up the

first ever production facility for biopolymers in russia. the pilot production. where the cultivation stage begin the next stage is to increase the quantity of the active substance that happens here and this a cool shake. material is transferred via sterile to. the first fermentation tank. then channeled into this container and it's here that the via polymer growing in the cell with. the material is fed into a vacuum. which is responsible for the concentration. that it is now ready for the actual production of the planet it can be done in that big extraction vessel all in this one we mix the by mouse with chemical agents and

after a few operations we get the result by a polymer we trade marketed as be a pass to town. not only do they have a product the lab also has its rising star. she's a vital role for bio plastics in the twenty first century induced me breakthroughs in applying beautifullest a ton to products in the field of medicine work that got her recognized with the presidential young scientists award in the halls of the kremlin in february of two thousand and ten with a boost from the national attention to her work is right back in the lab she essentially conducts subsidiary of the bio plastics project with a focus on medical applications it may not be getting rid of all those water bottles but the impact is just as important like our planet poisoned by piles of trash the human organism is incredibly sensitive to the influence of harmful substances and to keep making lifesaving advances in medical treatment we have to find benign ways to operate in medicate inside the human body. can you make from

this polymer is it the hope of the middlemost there are lots of potential products and biomedicine we study this material for various applications and surgery it could be helpful for example as a retention see a chair or as a particular implants that are used to treat ruptures it is an ideal material for stents implanted to restore bile passages or bone tissue we can regulate the size of the implants make it bigger or smaller we can also tailor their geometry to fit specific requirements we can adjust their density and per our city hammock and another promising field is drug delivery and controlled release here also size and shape could vary here you can see a macro implant carrying the drug but it could be micro and nano particles that will do. over the substance to its destination we've made it to clinical trials for to killer and. and tubular stands for passages and initial tests are underway.

and the rest of the others are still in various stages of development doctors are constantly faced with tradeoffs between fixing the existing problems and risking new ones the shining prospect of biomedical products like these points to maybe one where the conflict is minimized by using instruments that interact naturally with our bio systems. we have good potential our material is on par with similar products developed in the west and some aspects even better there are vast prospects for use in biomedicine. we will be able to reconstruct various types of tissue in organs it will be ideal for tissue engineering that is the reconstruction of something that's been lost. theoretically we think it would be possible to use our material to synthesize a whole organ and give it to those who need it. biomedicine focus complement each other quite well forming a complete technological cycle from the idea to

a concrete implementation with respectable production capacity because researchers have already extended offers of ideas expertise and even their patented bio polymer to colleagues in russia and abroad who are on the same track it's a model that's ready to be picked up an expanded applied across the broader spectrum of fields where our planet needs us to switch from petroleum based polluting plastic to the something from nothing eco friendly future of bio plastic . system we inhabit demands this attitude of given take technology we've developed is help us find more of use in the world that surrounds us and if we're savvy enough it's also helping us get the right things back. so it was. in from the tiniest micro biological systems the problems of our global ecology are all under the scope of today's top scientists and with the assistance of innovative new equipment we have more than ever information about our

planet right at our fingertips that's all for the show join us for more next month on technology update until then enjoy the ride this is data data generated from an electrical grid from wires streets businesses homes. when you can harness data you can do things you couldn't do before. prepare for alternative energy sources celebrate the adoption of electric vehicles help prevent blackouts see the data from energy usage as it happens and you can do to do it in places like california and build a smarter energy system let's build a smarter class.
