they want to know what makes the devil you. the german the love. ballad going way up. on live in other words like oh my god and everyone with a leader was an every. day are you ready to meet the servants and join me right just do it under a w. light can be a hop skip and a jump for the young. but as we get older we may need to invest a little more effort to stay fit physically and mentally and so you just want to help somebody have found a way to boost and aging memory. all that and more coming up welcome to tomorrow today the science show on t w. a magic youth potion for the mind well not quite but there is promising stuff in

blood plasma the yellowish liquid part of the blood that can be separated in a lab from the blood cells. contains lots of proteins divided into 2 classes albumin and globular. among their functions transposing hormones and enzymes and aiding the immune response. you are scientists in california have made some pretty astounding discoveries. many of the ideas that have come out of silicon valley have changed our world. here at stanford university tony vickery from switzerland is doing research into aging and out simon's disease that. is aging is the main risk factor for all timers. and that started me thinking about why we age. these so called. i suppose totally from.

united by that is what determines the lifespan of an organism. now can we understand that and then manipulated organisms this corey and his team began looking for a substance that could delay the aging process or even reverse it a rejuvenating therapy. and this is their great hope blood plasma. go home and those where we studied arose 2000 proteins in blood plasma was gone before us and we discovered that many of those proteins change as we age to you know quite a lot of protein that you don't want to increase with age. while the others that are pretty good well lost as we get older you know if you're fairly young you talk to. the scientists used mice to test how the blood plasma proteins affect the aging process at 10 months these mice are already elderly like humans

the older my shows signs of cognitive decline such as memory loss. in this test the mice have to find their way back to the hole that they can actually cool inside. the scientists tested how young and old the mice performed in the test the young man's here on the left finds the right tone in just over 20 seconds while the older mouse on the right takes nearly 4 times as long. the scientists then give the older mice blood plasma taken from the younger ones the effect is amazing. their memory has improved and the older mice now find their way back to the right old just as quickly as the young mice. there's even been a biological change that can be seen as a test showed the older mice have actually developed a new brain cells. so could this region even a shin work on humans to in

a pilot test 18 older patients in the early stages of alzheimer's where injected once a week with plasma taken from young people. after a few weeks the scientists tested whether the patient's membranes had improved us for parts and the things that are very important for patients or activities like being able to button up your shirt and clean your teeth and it supports my daily activities of living as we say he's living on the house so that's what we measured and we discovered that there was indeed a significant effect if you think it does it has the patients who received blood from young people displayed certain improvements doc it's a focus on it's like so what we're able to show is that changes related to aging can be pushed back through this process. which don't get picked up so indeed it's reversing the effects of aging to

a certain extent so i'm curious and we continue. the scientists are hoping to repeat these very promising results in largescale studies and they're also trying the method on another disease parkinson's. snail slime is said to do wonders for the skin like this action is a quick fix for the body. some people go to great lengths to stay young for at least looking on but there's no injection that will halt aging in its tracks is living a long life just a matter of luck. some things we can't control other factors maybe we can. 5 tickets to longevity in the lottery of life 1st and foremost genes. that basically we get from our parents. it's often the case in families

that the parents live to a great age so do their children. the right d.n.a. is a big. british researchers have discovered genes that are directly related to life expectancy. in one particular gene the immune system for example which can have a positive effect on how long someone lives. in general having the right genes can increase their life expectancy. it's estimated that 25 to 30 percent of the variation in human lifespan is down to d.n.a. . gender is the 2nd ticket for a long life. women

have a higher life expectancy than men in germany they currently live almost 6 years longer on average. but when men and women lead the same lifestyle like monks and nuns in a convent the women's advantage. 'd still runs in convents live nearly 2 years longer than monks. one explanation for this could be chromosomes. women have 2 identical x. chromosomes. men on the other hand have one x. and one y. chromosome this makes them more susceptible to genetic defects. and for men like testosterone may be more likely to cause cardiovascular disease. nutrition is the 3rd ticket to longevity.

a good and balanced diet plays an important role in staying healthy and can help us live longer. one good example is a mediterranean diet all of oil digestible zone salad along with whole grains can actually extend our lifespan swedish researchers have proven the life extending effects of such a diet of. calories we consume also has an impact on our lifespan. those who keep their weight in check by eating in moderation can expect to live longer. positive attitude to life is ticket number for. you this. was early 1979 researchers in the united states discovered that people who have a positive attitude towards aging live longer.

in a long term study that lewis terman started with children in the 1920 s. surprising facts emerged 80 years later about lifestyle in old age. corning to the study relaxing with golf in retirement didn't help but those who continued working after 65 lived significantly longer by an average of 4 years. so being active in old age prolongs life. exercise is the 5th tickets. sports and exercise have a significant impact on our health and the way we age. job is for example see health gains in old age that continue long after they've stopped jogging. researchers found one reason for this when they tested people

who suddenly trained hard. after a few weeks they could see changes in cells that were triggered by training the cells and body were fitter and better equipped for old age. 5 tickets to longevity genes and gender a look of the draw. a positive attitude and exercise we can all help to increase our life expectancy. a life without change which would be pretty dull. transforming your appearance might take some time and imagination but it can be done most of the time what about tweaking the personality. the way you feel and behave well that's a bit more difficult. it's said that we can change ourselves if we want to get hot which is not so sure

about that he's an neurobiologist and he says the brain doesn't like to waste energy. as brains are greedy and expensive and in terms of energy is always working full out in order to change it needs a lot of energy for various reasons for change means the brain has to rewire itself brain simply generate the feeling why should i change why should i exert myself. anyone who wants to change the habits and traits they developed over the years 1st has to overcome some resistance. up personal attributes or only partially determined by our genetic makeup they do change over time in response to new experiences and then there's new plasticity the capacity of neural networks in the brain to grow. andry organize making learning and change possible

even in old age. but it would be naive to think we can change our ingrained habits of thinking feeling and behavior in short our personality just like that. our personality is shaped by prenatal and childhood influences those emotional and behavioral patterns a buried deep within our limbic system a primordial part of the brain that's only barely accessible to conscious intention . to use a term of the senses which operate or not consciously do something very important they evaluate everything we perceive experience think feel and do when we're done and then they register but good do it again or that's bad painful and don't do it again for those less do. and since we tend to avoid painful

feelings we usually remain true to our habits so deeply anchored behaviors often prevail even if we would like to shake them off. it's only when they cause us a high degree of distress that enduring changes will occur. people whose established personality repertoire causes them problems and who see no way forward might be ready to try to rewire their brain. is going to has to be the prospect of some benefit the change will mean the distress we feel is gone or at least reduced the 3rd factor alongside reducing distress on the prospect of reward it is all patients just good old. that means perseverance even in the face of. setbacks and coping with the uncomfortable

feeling that our current reality doesn't match our dream another important question is whether we want to change for our own sake or to please other people. another precondition for change is the untapped resources we bring to the process get much won't solve that during his work with juvenile offenders in sarah piece some of the young people were able to make positive changes even though they've been abused and neglected as children are bask up to i mean they have had an attachment figure on court and to a teacher i would use about someone who they told me gave them some stability and support. that relationship helped both for the suffering that have been inflicted on them a good person lyndall that was an inner resources they brought to the table and the source of. those inner resources that spark of trust openness and empathy are an

important wellspring for change. get hot who are trans a consulting business that offers change management for companies just like individuals businesses can be stuck in destructive patterns but when holt tells them that real change takes time some refuse to play along your arm i'm in the field the higher up you go in the management hierarchy this the less the people who wield the real power to put it bluntly are willing to accept change and so as a lower and middle management the more receptive those all whom i'm call higher ups are much more impervious this because change always means changes in who holds power no friend or former. change takes

motivation the prospect of reward resources and lots of patience shaking off unwanted habits can feel risky even painful but people who can cope with those uncomfortable feelings stand a much better chance of achieving lasting change. just lay back and stare at the sky let the mind wander reflect on the nature of the universe. and you might just stumble upon a question for science like aka anion as you go from gonna. he'd like to know. does the sky look the same from space as it does from earth. on a sunny day from our standpoint the sky is blue. hair composed of invisible gas molecules gives the skies this color. as sunlight pastas

through air these molecules scatter the blue component of the spectrum of visible light in all directions. and that's why the sky looks blue but just to those of us on earth. the international space station hovers above earth's atmosphere when the asheron's look out the window they see our sky above. when they look directly down at the earth's surface without any clouds the astronauts can observe many glorious colors. in the atmosphere only appears as a thin blue line on the horizon. 'd 'd looking away from the earth into space which has no air they see a black sky filled with stars the stars appear as tiny bright dots when it's. time

on earth the sky is also black to us but earth air causes the stars to 20 and it makes sunrises into colorful spectacles because the layers of air filter out different parts of light. in contrast and airless space some light is white. sometimes clouds darken our sky they block the light as clouds increase it gets darker on the ground. but seen from above clouds appear bright because the sun is shining on them. whether satellites have a wide view of earth. they study the error in different spectrums of like to detect different temperatures or to find of clouds have water or ice and how quickly they're moving. this data is used to predict if we can look forward to enjoying blue skies tomorrow.

if outlook is red why are they buying it do you have a science question you'd like us to answer. send it in as a video text. if we feature it on the show you'll get a little surprise from us as a thank you. come on just toss. and for more exciting stories about science check out our website go find us on twitter. and it's because as an exciting if not troubling reports about trees. around the world forests have to put up with the launch fires fanning climate change. in germany ash trees are under a special flare we head to the south of the country to meet some reason. such as he

went to save them from a ruthless. a forest in lands who'd in bavaria these 2 men are after a killer that's been claiming a growing number of victims throughout germany and is proving relentless. right now i don't think we'll see any let up here for. the killer is a fungus that preys on ash trees. today close down my heart and michelle pfeiffer looking for some of the trees afflicted. i've been observing us trees in the area since 2005 and the picture has changed massively. the speed at which it spread over the past few years is not a good development. yet the ash is considered

a species that can cope well with climate change its wood is a favorite of the forestry industry. the clandestine killer is hymen o.c.i. 1st frank serious a fungus that grows on the forest floor and produces wars. they are then spread by the wind with some landing on actually where they subsequently germinate. the fungus feeds on the tissue which slowly dies and believes with. from here the fungus threads to the shoots and branches it works its way to the bark and trunk where it again leads to dead on across to tissue. once the fungus is in the wood the disease restricts the flow of water from the roots to the crown and the tree is weakened. if the tissue at the base of the trunk is attacked other pests can invade like ash beetles all the are malaria fungus in the worst case the tree said.

or. monster like this wonderful huge ass tree. when the trees like. it makes you want to cry. when the roots are rotten even a tiny wind can topple an ash tree a potential danger for walkers that's why michelle find it includes marking ailing trees they will be cut down in the late fall when the bird's nesting season is over so how are things looking. trees here seems to be in good condition especially the one on the left. experts believe that about 5 percent of ash trees are only slightly impacted by the fungus they seem to be disease tolerant something research is want to take advantage of the tuna and institute up in brandenburg scientists

francisco past and ben people planted cuttings of ash trees they think are tolerant then they infected them with the fungus on the trees showing any effect. so we hope to see nothing although that could also mean the trust didn't work that's always a risk. hopefully we'll see a couple of places where there is something to see and a couple more where there is nothing. small wood chips infected with the fungus were inserted into the bark of the tree the 2 researches assigned school was from one to 51 means the tree shows no signs of damage find means its dead. cutting gets a warm fuzzy here's where we put in the word. it just fell out. no interaction is a ball no black lesions kind of. so far there are no traces of the fungus on the cuttings that. then. a classic

case. it's really sad luckily it goes slightly i noticed in the green jungle but of course it's a bit alarming when you have to take one out from the middle all swearing was the experiment still a success the masters and most don't shows it's just a few that do as we expected. to save the trees further research is being conducted on the tolerant ash trees using state of the art technology. the genes of these trees will now be studied because it seems tolerance can be inherited in addition the researches want to understand the disease better and obtain the most tolerant seeds possible. that hope. that we can preserve that as an important economic and ecological tree species and forestry purposes and that it doesn't become a marginal species if you work. here at the tune and institute small ash cuttings

and already being propagated and grown indoors for now creating the perfectly resistant ash tree in the lab remains the stuff of science fiction. back in the forest in bavaria. ordinary people don't necessarily see what safety risks least partially damaged. because of this there's always criticism. criticism of cutting down trees but safety comes 1st even if the sash cannot be replaced the forestry experts will still have to look for alternative species and there is a chance. because research can accomplish anything but we'd be the 1st to welcome it. we still hope that something can be done. that the fun. will stop claiming more victims and that the deadly rampage will have

a happy ending in years to come. aboard. that's all for this week on tomorrow today we look forward to seeing you next week until then good bye and stay curious.
