no it is simply. to get. discovered. substantial documentary. some plants and flowers are equipped with veritable superpowers once you know what they're good for stay tuned to find out. we also need to go with autism who's getting special type of therapy to help her cope better with everyday life. and they might be tiny but we shouldn't underestimate them we take

a closer look at monies and how they communicate. welcome to tomorrow today science show on d w. animal is that low grunt obama it's their way of defending their territory coming their fellow creatures finding partners. but. we humans can't always hear them bats and whales for example emit sounds in the ultrasonic range. but they know so alone. if you go down to a cellar today you might be in for a surprise and if you hear one mouse scurrying around to the next one to be far away. house mice are pack animals rather than lone wolves and researchers have been

investigating their complex social lives a key point is the secret communication used by the small rodents mice scent marks and similar to bats they emit sounds and the ultrasonic range that is in humans. to understand more about the so-called mouse songs a research group at the university of veterinary medicine vienna set up live traps in place where mice aren't welcome dog. and. marconi have to check the traps regularly a painstaking exercise one that's vital for the research. we have in madrid was we want to work with wild mice to study the natural behaviors and the functions of songs in the wild things that sometimes extremely in brad and wild mice of very different and that behavior. that makes wild mice more suitable

candidates here at the con had long since institute for comparative behavioral research the ultrasonic songs of mice were discovered back in 1049 but it's only recently become possible to make them and all their complexity. for her 1st experiment dogs nickle luckiest chooses a male to confront with another male in the neighboring cage. a highly sensitive microphone records the ultrasonic sounds she uses a frequency diagram to make the sounds visible. but it's only when she slows them down by a factor of 20 that the whistle like sounds can be heard. this mentioned this and it's this my own head doesn't seem to show much interest and we can tell by the fact that the songs are relatively simple and there are no

big jumps in frequency and what's interesting is that these songs are sung at relatively low frequencies. but will that change when she swaps the one male with the female the 2 mice begin to vigorously sniff each other the sounds become much more intense. as a human to get sing so hear the songs already seem a bit more impassioned. i do already see more variations in the individual syllable . and they've risen to a higher frequency between 60 and 80 kill her that's. as soon as a potential mate is nearby the male begins to up his game and his frequency in an attempt to woo her similar to the courtship songs of burns and the scientists notice something else we found that there are indeed. there are features and characteristics the need to look at is ishaan that might be different from one made

there and we found that there can see stems and so over multiple recording say you can that's a record highs that may. when the divider is removed the male mice become even more stimulated the singing now even includes jumps in frequency. as in sometime before overall we found unrelated paths interacting with each other directly have the longest most complex song these pairs with the fastest to reproduce successfully. as capturing wild mice is very time consuming she wants to use this insight for breeding 2. because once a pair of mice couple reproduction as a rabbit female mice can form pregnant up to 8 times per year bearing litters of up to 11 the tiny newborns grow for within a few days. the male mouse is highly aggressive when chasing away arrival.

he'll attack physically but also has another secret mode of communication using sense that he lives everywhere by a tiny droplets of urine. this is can use in skis field of research. he lays out sheets of paper in the enclosure that the mice walk over. he uses a trick to make their said markings visible. exposing the paper to ultraviolet light. i think the sun marks of maize are interesting because these chemicals that are in the summer's almost the thing that's closest to writing in humans they can leave a little message they can also use this to kind of show their territory where they're living and to also give information about themselves. by analyzing the contents of urine especially the pheromones listens he wants to find out what other function the scent marks have. to do this he compares the urine of different male mice

in a group. and we find that double that males have a higher expression of particular smells pheromones then subordinate males if we present these smells to a female we find that the female prefers the smell of individuals that have dominant slow compared to support let's. so both scent trails and courtship songs apparently help the mice to create optimal offspring and thus keep the species as fit as possible the team still have plenty of research to do as they continue their mission to unlock more of the secrets behind the language of mice. and our next report we focus on human communication in particular the challenges facing autistic children. a recent survey showed that

372 per 10000 children were diagnosed as having autism in hong kong and island 153 and in germany 38. special type of therapy could help to make everyday interactions easier. francesca is in her element in the forest a place where she feels comfortable and safe. oh here my. best francesca is 12 years old and artistic. bite for her the forest is a peaceful place to come she can deal with leaves and other objects far better than with another human being. and the big issue is communication and francesca has her own way of communicating. you can optimize to have.

question. yeah when you have a child who can't sleep at night they're naturally going to be irritable and aggressive. writes i think that's what makes everyday life so tough for a child with autism taxes. francesca was diagnosed with relatively severe early infant tyler autism therapists today referred to an autism spectrum disorder of which there are various levels the family's outings aren't always as joyful as this visit to the zoo and your mom might give me. we might go out for a walk in the summer and then out of nowhere they'll be alone more for her a sound she can't place and one that makes her scared. me angst. this is

my point. today the bellowing of the sea lions is just too much for francesca. autistic people filter incoming sensory stimuli differently than others some are not so sensitive others like francesca feel quickly overwhelmed and retreat into their own world. children like francesca exhibits stress symptoms and might develop tics some self harm or become aggressive and hunches. and when they're unable to express themselves through language they might resort to more desperate means of communication. as issues this is not some of the worst moment for me was when she tried to play with another child at the playground but it wasn't possible i think she realizes that she's different to the other children she ended up biting the other child slank. so what can you do when your child shows that kind of aggressive behavior the

autism outpatient clinic in your own back office parents advice and support. learning therapist caterina floor uses pictures to help the children communicate. francesca is given a schedule containing symbols that show her what to expect in this therapy session . first up is learning how to set the table. so asking people to market the problem is that people with autism on typing to respond say well it is the only language based on me and i don't know and they often need a visual. and that's where these pictograms help. someone posts they often have difficulty understanding the context in question no i thought. this is which was 1st developed at an american university is now used around the world the visualisation helps the children in their temporal and spatial orientation both of

which can be a huge struggle for people with autism. today francesca is more in the mood for playing. once she's completed an item on the programme the picture card is put in the done box the clearly structured set up evidently pays off. kinda heading inland i've met nursery age children diagnosed with early infantile autism. they couldn't talk about enough for us a few years later they'd made amazing progress fun for some made it into the best schools with ongoing support and it worked well. the parents then practiced the activities with their children in everyday life. the cards help francesca to give a structure to her daily routine at home and at school. so you put those clothes on today right. so it goes into the box. for the past year francesca has only

spent her weekends at home otherwise she lives in a special home a desperately tough decision for her mother to make but she felt unable to cope so i was set it was really stressful because you feel that you failed as a mother you want to be there for your child but i got to the point where i just couldn't do it anymore. for mismatch it's a move that has benefited the family. back at the zoo francesca and her mom are trying an experiment by going to the on site restaurant how will francesca react to being surrounded by other people after some initial discomfort she starts to relax to the pleasant surprise of her mother. and for me shoots god i'm so happy right now to see her sitting still a couple of times before she ran around moving trees and what have you. so i had to leave pretty much right away in. the garden and. it's another little step

forward on a journey that mother and daughter will be taking together and they're planning to come back to the zoo as soon as they can. 'd it's indisputable social media plays an important role in modern communication since 2015 the number of users has leapt from over 2 to more than 4000000000. in the philippines people log on to social networks for an average of 255 minutes that's more than 4 hours a day compared to 186 minutes or just over 3 hours in egypt 84 minutes in germany and 51 in japan. and what about you how much time do you spend on platforms like facebook twitter and instagram and how has social media changed your lives we asked you via d w social media platforms of course. primo malala writes social media has made

communication easier but there are also alarming aspects such as hacking misleading information and other negative content. marcus demers spends a lot of time on social media learning something new almost every day he uses to talk and facebook as sales platforms pinterest and google for learning line and twitter for news. one taras poses the question the other way around he writes it would be better to ask how long we don't spend on social media it will be easy to work out. the opportunities of communicating with others are practically unlimited given the sheer number of platforms what has that made us any happier for the opposite travel daniel from nigeria had a question about that. can spending too much time on social media make you depressed. instagram.

the number of platforms has been constantly growing as has their global popularity and has soared during the pandemic of users. can stay in contact with friends and family share information and stave off boredom all under lockdown but social media has always been controversial numerous studies suggest that spending too much time on such websites can lead to an increase in symptoms of depression amongst users. but is there a causal link here is it spending time on social media that makes people depressed or do they take to social media because they're already depressed the caustic question of which came 1st the chicken or the egg a recent study carried out by the american universities of arkansas into pittsburgh sheds more light on the issue users were monitored over a longer period 990 of the 1300 test subjects exhibited no signs of depression at

the start but after 6 months of high social media use $95.00 of them had developed symptoms. more research is needed before any definite conclusions can be drawn but in the study it was precisely those who used social media the most who develop symptoms. one factor causing depression may be that social media takes up a lot of time meaning other valuable pursuits come up short. another issue is constant comparison and the resulting pressure users feel to measure up to the impossible ideals of beauty and success that's especially the case on instagram the brain also has to deal with sensory overload as it struggles to respond quickly to the mass of information and images incidentally in the current pandemic the question is also how lockdown measures affect our social media consumption and

whether it's excess usage that's driving depression or the lock down itself or could social media actually help alleviate depression in some cases here choosing more research. if outlet is right why. do you have a science question you'd like us to answer. then get in touch you can send us a video text ovoid if it makes it onto the show we'll even send you a little surprise as a thank you come on just stunts. you can find more interesting science stories on our website and on twitter. accounts communicate with one another they do this via chemical substances that they emit from their roots and leaves. with color and fragrance they attract bees

and other pollinators to help them reproduce after all they can't go on dates to find a partner. some plants like corn have other amazing tricks up their sleeves researchers are hoping to harness those capabilities. this is no ordinary garden in the eastern german town of flyback what looks like a random array of plants in fact comprises carefully selected species with genuine superpowers. it's called final mining which is basically mining with plants we use partly conventional plants like corn to extract economically relevant elements from the soil such as germanium and rare earths and also gallium copper and zinc. it will now become apparent how well the corn did its job in the summer because it's harvest time a big day for biologists. who initiated the project at the local technical

university but what makes the plants take in the various elements in the case of corn it's all down to a curiosity of nature. and as such what's. to absorb silicone grasses in general are silicone accumulators. they extract silicone from the ground and store it in their leaves. and the silicone then forms little stones that protect the plant from being eaten. shoots or and they have no option takes place via transport mechanisms which due to a whim of nature cannot distinguish between silicone and germany i'm. going with a side. which is why the act like dick makes the plants and flowers in the experimental garden then makes sense corn as we've heard collects germanium whether it's farm for animal or human consumption the similar looking millet does the same

buckwheat on the other hand stores rare earths and its leaves and stems as do sunflowers. why is that relevant rare earths are a group of 16 different elements with similar chemical properties. they're used in everything from mobile phones and l.c.d. screens to electric motors and wind farms. germanium is likewise used in high tech products in phones and solar panels and fiber optic and computer cables and night vision equipment. germanium is also expensive one kilogram currently costs around 2000 euros so researchers are looking for cheaper alternative ways of extracting the precious substance this is how it works the corn mistakes germanium for the silicon also found in the soil that absorbs them both directly via its roots. the

germanium is then guided along with the silicon by so-called transporters through the stems and into the leaves. here like silicon it is stored primarily and the cell walls. millet extracts germanium via the same method but buckwheat and sunflowers used a different trick. you might normally associate buckwheat with healthy organic cooking but it also happens to boast unexpected super powers it's able to mine rare earths out of the ground the buckwheat does this by extracting calcium in the process acidifying the soil around its roots the acids caused the phosphorous and iron that the calcium is found in to dissolve also releasing the rare earths that are in the phosphate rock. they all then migrate to the leaves by their stems here

they are stored in the cells their walls and in special water reservoirs come back . the final mining project at the university of fine back still has a long way to go but all of a vicious says the potential in these plants is enormous the burden to. constitute the biggest source of these elements on the planet for centuries to come we could farm and harvest these crops and every year we find the same elements in the plants . of course in order for us to use the rare earths and other precious raw materials they 1st have to be extracted from the plants and that happens here at the universities bio gas plant the corn is turned into tiny chips and dried out before being weighed and poured into a reactor device together with the quantity of water here bacteria assumed 2 important tasks they generate bio gas and break open the plant cells the resulting

product is a liquid that is then dried out in an oven. this is they give us this is the digest tape with and yet. for us it's a can to plant or containing all the elements which we then want to make available for use. and that now involves burning the plant residue. those treasured elements are then found in concentrated form in the combustion residue caches. that use up the ports as though the entire process takes around 30 hours what we then get which you can see here are innocuous looking white and colored powders. germanium dioxide and rare earth sauce sides and they will then be used in e-cards in cell phones and scientists. the researchers aren't yet able to say exactly how much the test garden

in feinberg will harvest in terms of valuable all materials so far they've been able to produce around 50 grams of germanium and 50 grams of rare earths perfect air not much perhaps but for all of a vision and his fellow researchers a very promising start. for germany as an industrial nation it's massively important to have alternatives to regular imports of raw materials. i say this process needs to be turned into a pilot project as soon as possible to be usable in the future. that's what. the potential in such plants has still to be fully determined some of them even have the ability to extract toxic heavy metals out of the ground on the fido mining front the researchers are confident of discovering further super plants with powers that we can harvest and harness. another big step in plant research

this is due to reduce life from berlin death and destruction and despair the u.n. secretary general condemns the sense of the cycle of bloodshed in the middle east but there's still no end in sight. to. the israeli military use pounding gaza pressure for a cease fire grows permissive prime minister benjamin netanyahu says the gum gardens of the enclave will continue with full force and into newfound freedom people in britain will be able to enjoy a pint in doors hug their loved ones and meet others at home but their relaxation

of lockdown rules is marred by concerns about a highly contagious colonna virus very. on one of the rock a very warm welcome after a week of fighting there so no end in sight to the deadly violence between israel and militants in gaza ceasefire appeals continue to go unheeded and residents of gaza have experienced the heaviest bombardment by the israeli army since hostilities erupted a week ago while israel says it destroyed tunnels used by militants and the homes of hamas commanders and u.s. secretary of state anthony blinken says washington is working diplomatic channels around the clock but the u.s. is stopping short of demanding that israel halt its bombing campaign.

the aftermath of israel's latest ass strikes on gaza residents are left picking through the rubble that used to be their homes they say the attacks were the most fertile roche's yet. i fear ministre fear we will certainly scared especially the children we feared they would be wounded that they would die or be buried under the rubble israel says it's aiming to destroy terrorist infrastructure and is targeting militants the army later released footage it says shows strikes killing a senior palestinian militant commander israel's jets also targeted an underground network of tunnels used by the militants in the early morning raid. on a residential complex in the city of ashdod hit by a hamas rocket had masses kept up its bairagi in southern israel not all missiles are intercepted by israel's defenses as the bombs keep falling the international

community is becoming increasingly alarmed more or less the u.s. says it's working to defuse the situation. united states remains greatly concerned by. by the violence by the escalating violence hundreds of people killed or injured including children being told from the rubble we'll continue to conduct intensive diplomacy to bring this current cycle of violence to an end. because the killing continues violence fear and loss remain an every day experience for these children in gaza. have actually turned out to w.'s tenure kramer she joins us now from jerusalem tania we know that gaza has come under the heaviest bombardment again what's the latest information you have for us from the enclave. well it is an

extremely difficult situation for people there as strikes have continued i talked to some people there on the phone as journalists we cannot go into gaza at the moment and they have told me you know also overnight there was a very heavy bombardment and the situation is 16 it difficult because people have no we have a safe place to go so it's just constant pressure not knowing where to find safety at the same time there's a lot of concern also focus with become homeless because some residents of buildings have been targeted and destroyed and also a lot of people that are seeking shelter more in inside you and schools so the situation there for people is really very difficult now after a week of fighting between hamas and gaza bring us up to date please if you can about the situation on the israeli side. but as we speak retest received. more alerts for incoming rockets they usually come in waves now they are

targeting at the moment again mostly the south of israel cities around. and the envelope around gaza so as long as rockets israel would say that will defend themselves of course and be heard in public statements prime minister binyamin netanyahu saying that they want to continue this campaign there is of course international pressure to come at some point to a cease fire but i think that also domestic considerations here there is the sense that at this time there needs to be really a decisive achievement against hamas they are continuing also firing rockets so it's unclear when israel will actually go for a cease fire disappoint and what can you tell us about any diplomatic efforts that are currently underway. well there's so many conflicting reports coming out and you have to be that between the lines of it but we know there are mediation efforts

going on behind the scenes you know the united nations here the u.n. special envoy. is involved and of course also egypt egypt has established channels they've done this before in previous rounds of hostilities also during the previous 3 wars between hamas. and israel so they have a leverage they have an interest as well and we also understand jordan's king abdullah has said there intensive diplomatic efforts going on and we also know that the u.s. and roy here is still on the ground but at the moment it's very difficult to say when there would be a breakthrough and when both parties hamas and israel will agree to such a cease fire tanya kramer and jerusalem thank you for your tireless reporting. let's bring up to speed now with some of the other stories making headlines around the world hong kong media tycoon and pro-democracy campaigner jim eli has pleaded

guilty to taking part in an unauthorized protest in 2019 i mean your company mr ally owns has halted trading of its shares after authorities 1st his assets under the territory's national security law and that sparked concern about press freedom in hong kong. i mean mars election last year did it reflect the will of the people according to an international monitoring or group the asian network for free elections set the army was unjustified in using alleged election flaws as a reason to seize power around $800.00 people have died since the military coup began on february the frozen. parts of the u.k. are easing lockdown rules today that's despite concerns over the spread of a coronavirus variant 1st detected in india pubs and restaurants are opening open rather for indoor drinking and dining after being closed for months of people

are also allowed to meet at home for the 1st time since last fall and holiday makers are arriving in droves in portugal one of the few countries the u.k. has designated as safe. but in the town of bolton near manchester it's one of the places where case numbers are spiking to correspond bill is standing by charlotte what role does the indian strain play in bolton surge in infection numbers. well the strain they are at the moment is costing something of a dark cloud on old days not down measures which are being eased here today in england we've heard today from the health minister that this is now the dominant strain hair in bolton and other parts of the north west of england we know as well that this strain has been identified in numerous areas across the country so it is

something that or 30 is a watching very closely here in bolton the health secretary said that in the last week the number of cases has doubled there's been another surge that he announced again today so it is certainly a cool for concern one of the issues here is that there is a lot that still isn't yet known and one thing that authorities are keeping an eye on in the trying to gather data on is just how transmissible this new variant is now we've heard that it is more transmissible than that previously dominance or strain in the u.k. the kents variant which has to face spreads to the rest of her which is spread outside the u.k. you know it's more transmissible not the question is how much more transmissible now some months is the warning that if it's 40 to 50 percent more transmissible that could cause real problems here in the u.k. and does put the on looking for strict sions out risk the other mushkin is what effect this strain has on vaccines that we also see that says that the health secretary said he's relatively he has confidence that vaccines will be unaffected

but the warning is of course that not everyone in the u.k. has had a vaccine the vaccine campaign has been very successful some 70 percent of adults with how to the studies but that does still leave a large number of people who are on protected in the health sector has warned that among that group of people the strain risks spreading like wildfire so that mean that the easing of restrictions is to apply to the city of bolton where you are. it does in fact yes the restrictions have been eased to today there have been i enjoy or hospitality restaurants pubs opening up about 4 different to scotland which is following a similar unlocking road map to england they've decided to keep areas that have seen case numbers rise glaus go for example under the same measures that they were before here in bolton no it's been decided that the the unlocking can go ahead as previously there are also some questions though whether this area will face the

local look down going forward as it stands there it is exactly in line with the rest of england charlotte chel some pill reporting from bolton near manchester thank you. and a pivot our attention to russian our court there or has decided to perspire on on whether to declare a group supporting jailed kremlin critic election of only as extremist or that ruling is now due next month or the designation could mean activists face long jail sentences for opposing russia's leadership to be is only sure when met with some of mr have always supporters to find out about the pressures they now face. this letter seals the deal it officially ends on the contract with these team andre head of the opposition politicians regional office and to be had for 4 years . russia will be free he says one day was arrested at recent an authorized protests

his team organized into the air but now his office along with 36 others in the violence campaign network have had to close russia's state prosecutor wants them declared extremist and then he tells us he wants to create a new local political organization to keep working. for politics was always centered on the russian capital moscow but thanks to the novelli campaign offices political activity has bubbled up across russia's regions roots now it's time for us regions to jump into the deep end and swim for ourselves it's hard and dangerous but it's a necessary phase in the development of political life not only in fear but across the country. and that he and his team into their have become friends over the years like andre most of them have been arrested several times and i've accepted threats and pressure as the price to pay for pushing back against the kremlin but the extremist label takes that to another level it could make symbols like this

a relic and for now viney illegal activists found to be part of an extremist organization could face up to 10 years in prison. i lost my job and when i tried to get a new one recently they told me in private that their security service wouldn't let . them hire me we have already had problems with work. if they really start tightening the screws and i see that they're making a show of putting former employees activists and volunteers of the not only offices in jail of course i will think about how i may have to lay low somewhere for a while. but. even people outside of actual team have been facing increasingly serious consequences for protesting against the government earlier this year thousands were detained during demonstrations in support of me and there have been several reports of employers firing people for backing the politician since the recent protests in support of. kremlin critics across russia have been under increasing pressure and

that pressure is unlikely to let up ahead of parliamentary elections in september including for the activists here. but. is unrelentingly optimistic the 31 year old wants to keep pushing for a more democratic russia and he says he's willing to take personal risks to further strengthen the role of civil society in his home city and the whole to their region . but have some similar them got the order to remove some of the example of alexina volley who came back to russia knowing that he would almost definitely be arrested strengthens my sense that sometimes you have to pay a personal price in order for you and your country to have a bright future see a clear winner shoot isa very serious thought on them now and that he wants to register as a candidate for the regional parliament in the upcoming elections he hopes his

association with now by nice team won't get him barred from running. and i sure want reporting stick with us the news continues right here it's a business up next with stephen beardsley and also look at the top of the hour. is code. johnson species. the expedition. looking to decipher the secret language of orioles 1st the exciting part of underwater listening is here and we know him so there is there life that

excess working hours are contributing to the deaths of hundreds of thousands a year around the world. globe welcome to the show m c. well monday is world telecommunications day that's the united nations effort designed in part to draw attention to the digital divide and that divide is especially glaring in africa where less than a quarter of the population has access to broadband there's been progress but khan it still needs an additional 500000 kilometers of fiber optic cables and that won't come cheap a whopping $15000000000.00 in fact now in the meantime customers are forking out a lot to get on line 4 of the 5 most expensive monthly packages for fixed line broadband are in sub-saharan africa with eritrea topping the list prices for mobile data meanwhile are all over the place running from as cheap as $0.51 in algeria to just over 2 and a half dollars in south africa and all the way to a nearly whopping $50.00 a gigabyte in equitorial guinea. all right for more on this let's bring in martin

shopper he's a senior analyst at the united nations international telecom it telecommunications union martin good to have you on the show those prices ferries that we solve there between $0.50 and $50.00 for a gig about what's behind it really depends on the on the country as you said but in general it depends on the operators in the countries are there and operators in the countries in most countries in africa only one operator or 2 main operators. infrastructure is very expensive that that this is. a very important point and lots of africa in many parts of africa actually have a lot of looking infrastructure putting up the of structures very expensive because the infrastructure comes at international prices and this reflects in the price that people have to pay for their connections and is as you say is money the

biggest thing that's needed here investment yes i think it is certainly true to put up the electing infrastructure but also the affordability for people and the point though is that the people in africa they they lack the incomes so the infrastructure needs to be put up at the international prices that people have to pay it in local prices and that creates a big gap where the smoothing restrictions between countries are standards between countries so that there can be some sort of regional smoothing of. the ability to basically the companies can work across borders are we seeing this more often we know that africa is trying to lower its trade barriers what about in the internet infrastructure sector as well do we see that. well to some extent we do because if you look at the the operators that we have in africa many of them broke more than one country fota phoneys is

a big player or halt in the in the. francophone countries is a big player so they broke across countries bought steel every country has its own rules and regulations and that certainly could be improved upon yes martin what is the pandemic meant for this kind of investment or are these kind of efforts to work together has it had any of kind of effect. yes it's had a big effect but what we've seen for the 1st time and that that this quite remarkable is that if you look at the number of mobile sellers subscription that has come down actually in africa as it always has been an opera trend and even in developed countries it's still calling up and for the 1st time we see it's going down in africa and that's probably to do with the fact that people have less money less income that they cannot go out on the street to buy the same car so there's less demand for. the services for the mobile services and of course as i mentioned this a lot of parts of africa that are on collect that any infrastructure needs to be
