the wing. and young people clearly have the solutions the future up to. 77 percent now everything on d. w. o. . life can be a hop skip and 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 scientists want to help somewhere found a way to boost and aging memory. all that is imo coming up welcome to tomorrow today the science show on a d w. the 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 i'll be humans and globules. among their functions transporting homeowners and enzymes and aiding the immune response. nero's 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 with search into aging and out simon's disease. is aging is the main risk factor for all time as. it's up and that started me thinking about why we age. these so 'd called. us most totally fascinated by. that is what determines the lifespan of an organism us and

how 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 region of a nation sara page. and this is their great blood plasma. home goes where we studied around 2000 proteins in blood plasma. on the 1st course and we discover that many of those proteins change as we age to feel quite a lot of bad protein that you don't want to increase with a. while the others that are pretty good well lost as we get older you know if you're fairly 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 tests showed the older mice have actually developed a new brain cells. so could this rejuvenating shin work on humans too in

a pilot test 18 older patients in the early stages of alzheimer's were injected once a week with plasma taken from young people. after a few weeks the scientists tested whether the patients membranes had improved rice . look at 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 going to be so that's what we measured and we discovered that there was indeed a significant effect significant effect so that's the patients who received blood from young people displayed certain improvement documents a focus 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 and we're going to. the scientists are hoping to rip. these very promising results. 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 young at least. no injections that will halt aging and. living a long life just a matter of luck. things we can't control other taxes maybe. 5 tickets to longevity in the lottery of life 1st and foremost genes. that basically get from our parents. it's often the case in families

that the parents live to a great age so to their children. the right d.n.a. is a big. british researchers have discovered genes that are directly related to life expectancy mutations in one particular gene affect the immune system for example which can have a positive effect on how long someone lives. in general having the right genes can increase our 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. when men and women lead the same lifestyle like monks and nuns in a convent the women's advantage. 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 hormones like testosterone may be more likely to cause cardiovascular disease. nutrition is the 3rd ticket to longevity. well. a good balanced diet plays an important

role in staying healthy and can help us live longer. one good example is a mediterranean diet. boiled egg salad along with whole grains can actually extend their lifespan swedish researchers have proven the life extending effects of such a diet as. ringback 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. those early years 979 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 their. 920 s. surprising facts emerged beta years later about lifestyle in old age. and corning to 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 ticket. and exercise have a significant impact on our health on the way we age. drugs for example see health gains in old age that continue long after they've stopped jogging. research is 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 cells and body work fitter and better equipped for old age. 5 tickets to longevity genes and gender look of the draw but through diet a positive attitude and exercise we can 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 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 a brain is 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 change means the brain has to rewire itself brain simply generate the feeling why should i change why should i exert myself go on for 3 unknown vulgarly be undergoing. anyone who wants to change the habits and traits they've developed over the years 1st has to overcome some resistance. our personal attributes are only partially determined by our genetic makeup they do change over time in response to new experiences and then there's a new array plasticity the capacity of neural networks in the brain to grow and reorganize 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 top personality just like that. our personality is shaped by prenatal and childhood influences those emotional and behavioral patterns a berry deep within our limbic system a primordial part of the brain that so many barely accessible to conscious intention. use a term called the centers which operate or not consciously do something very important they evaluate everything we perceive experience think feel and do when done and then they register but good do it again or that's bad painful and don't do it again for those less fool. and since we tend to avoid painful

feelings we usually remain true to our having. 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 letting jure in 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. or so while. there has to be the prospect of some benefit the change will mean the distress we feel is gone or at least reduced a 3rd factor alongside reducing distress and the prospect of reward is patients. good old. that means person b. a ring 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 gephardt wrote saw that during his work with juvenile offenders in sara piece some of the young people were able to make positive changes even though they'd been abused and neglected as children are washed up to i may have had an attachment figure an uncle and to a teacher. or someone who they told me gave them some stability and support. that relationship helped as well for the suffering that have been inflicted on them lyndall that was an inner resources they brought to the table and a good source of. those in arizona says that spark of trust openness and empathy

are an important wellspring for change. get hot who want runs a consulting business that offers change management for companies just like individuals businesses can be stuck in destructive patterns twin holds tells them that real change takes time and some refuse to play along here among in the future the higher up you go in the management hierarchy this will be less the people who wield the real power to put it bluntly but willing to accept change. so as a lower and middle management the more receptive it's all room on call higher ups are much more impervious this is because change always means changes in who holds power. for another form of. 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 a canyon as they go from gonna. he'd like to know. the sky look the same from space as it does from earth. on a sunny day from our standpoint the sky is blue. there composed of invisible gas molecules gives the sky this color. as sunlight

pass' through air these molecules scatter the blue component of the spectrum. 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 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 night time on earth the sky is also black to us but earth air causes the stars to 20 and

it makes some rises into a 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 air in different spectrums of light to detect different temperatures or to find if 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 right. right right right. do you have a science post and you'd like us to answer. simulated as a video text over or see if we feature it on the show you get a little surprise from us as a thank you. come on just toss. and for more exciting stories about science check out our web sites on find us on twitter. our next record is an exciting if not troubling reports about trees. around the world forests have to put up with i'm not sure if i use fanning climate change. in germany ash trees are under a special threat we head to the south of the country to meet some researchers who

want to save them from a ruthless and. a forest an inland suit 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. is a fungus that preys on ash trees. today question mark 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 word is

a favorite of the forestry industry. the clandestine killer is hyman 1st fraxinus a fungus that grows on the forest floor and produces spores. 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 the leaves with. from here the fungus to the shoots and branches it works its way to the bark and trunk where it again leads to dead or necrotic 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 or the are malaria fungus in the worst case the tree simply falls over.

or. you see a monster like this this wonderful huge ass tree. one step off the. issue of bigotry 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 pfeiffer to include a marking a ling trees they will be cut down in the late fall when the bird's nesting season is over so how are things looking over. the ash trees here seems to be in good condition especially the one on the left little experts believe that about 5 percent of ash trees are only slightly impacted by the fungus they seem to be disease tolerant something researches want to take advantage of the tuna and institute up in brandenburg scientists francisco past and bent planted cuttings of

ash trees they think are tolerant then they infected them with the for. angus the tree showing any effect. not just cause even if we hope to see nothing although that could also mean the test 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 woodchips infected with the fungus were inserted into the bark of the tree the 2 researches assigned schools from one to 51 means the tree shows no signs of damage find means it's dead. cutting gets a warm fuzzy here's where we put in the wood chip. it just fell out. no interaction is a ball no black lesions kind of spots and is your own little dust so far there are no traces of the fungus on the cuttings but then. i will sort of just

a little bit a classic case. it's really sad but luckily it goes lately 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 show symptoms 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 tuna and institute small ash cuttings

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

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