lincoln a full of horror and full of sadness. that's what happened to now city yesterday, and it hasn't allowed any of us to sleep. cold. last investment. thousands, we're enjoying an evening. it's orleans phones or square friday nights. when witnesses say, a man begins stepping passes by with a noise, apparently at random. the attack of then disappeared into the issue in panic and confusion. police do not know the silence identity or motive, but believe he acted alone, save us festival goal is to submit videos and photos to help with the investigation of the mission. i'm trying to get to a concrete description of it is difficult because witnesses in shop cannot able to speak. they are old receiving can, but we need to piece together all the information to continue the search. the festival was suppose to celebrate zoning and $650.00 at the end of the 3, the weekends remaining events on l cancelled as

a city moans. and with this emergency still far from over the w report of the ascent as in solving and there was what is the atlas fee in like way you want it is an atmosphere of immense sadness. i've spoken to multiple residents from zoning game, who just said we could have never imagined something like this on a day where we're supposed to celebrate the 650 of anniversary of our founding and look, sewing is diverse city. this is something that the sell the festival actually wanted to celebrate. and when i was speaking to residents, they just thought how, how could this happen to us? how could this happen to community? and they just feel incredibly disheartened at the moment, and they're looking for answers which at the moment we have few to little when i spoke to police here, they said look, we can give you any information at the moment. all we can say is that we have a small presence here, and just in order to maintain public safety. but at the moment we've, you know,

they've wide in demand hunt, but there's the little more that they can say about that. as you mentioned in the report, they have asked, you know, i witness these people who are at the concert to share material that could be useful in identifying and hopefully finding the perpetrator. okay. i understand there's little the we can actually talk about them. but what we know, at least about how events unfolded last night. absolutely. so the attack started shortly after 930. and at 1st it was unclear what was happening at one moment, shortly after that police were informed. and within this, even the d j who was playing issued an account saying that he was told to continue playing in order to make sure that there wasn't some kind of mass. tammy, this, that's what we're talking about. hundreds, if not thousands of people gathered in this small square, not knowing what's going on. and eventually they were informed the music stopped.

they were informed of what happened. but at that time, the perpetrator had already fled the scene. so in a way the details are, are very uh, not clear, but we can say though that the police were responding immediately after being informed of what was happening. tell us more about the man hunting mentioned before the following this attack, that's now being launched of the so at the moment police having given much information. there were news reports earlier that a suspect was arrested. however it's, it's been clear now that that person is likely not tied to this. and again, this was all reported by news. we have no official information from the police that should be coming a little bit later. and we will have that information to you as soon as possible. but however, at the moment,

all i could say is that authority said they have expanded the man hunt outside of solar. again, they are looking for the perpetrator. but there's a little information that they can share now at the public. in fact, they're employing the public to come to come forward with the video material images that they might have taken from the concert. so they can have more pieces of the puzzle to find out what exactly happened last night. and who exactly is this perpetrator? the very latest they have from a reporter louis n as in zoning and thank you very much. thank you. the german chancellor phillips has reacted to the fatal staffings involving inviting on his official ex account. the chancellor would be attacked in zoning is a terrible incident that leaves me deeply shopped. she went on to say that the perpetrator must be called quickly and punished with the fullest extent of the little and the more analysis on that

comment. and on this incident, we have dw security correspond to, let's start with, it's thomas salts wrote the commenting that the, the political reactions and you know, it sounded tends to tell us more. what other politicians, perhaps the other thing the patients have followed the same line. we've heard from the interior administer, we've heard from the vice chancellor. there's also been reaction and from germany's president funds by this time i out time id in germany's head of state. and all of the comments follow the same line shock on the one hand. but it is insane that the thoughts with the relatives of the victims and basically stressing the need to find the perpetrator. this is particularly relevant because the focus now is specifically on that you're trying to find out who was behind that and why. base attack happened once those 2 pieces of the puzzle are clear. ones,

the public knows more about about those pieces of the puzzle. will put additions, be able to react accordingly. so depending on the motivation, depending on who the perpetrator is, depending on where they can find the knife, that will determine to what extent, what additions will react in the coming goals. they know it was an ice attack though, i mean, why? so few details released to the public when it's in the public safety essentially because authorities did not want to jeopardize their own investigation. so they want to make sure that they can carry out their investigations without any influence any outside influence if you will. so that's why this follows the fact that we've seen in previous similar incidents that will for our to use, especially local regional police. give initially very few details until they can have something more, which they can then tell the public. there is a press conference scheduled for later today. so this afternoon here in germany, where authorities will probably give more details but for now they have the site to

carry out their investigation without having to inform the public of every single detail of what is happening behind the scenes. are they still trying to determine the bulk of absolutely the task? if not, if not one of the big questions, the most important element, because the motive determines separate it to go reaction. if the risk, for example, that political motivation, then that will determine how politicians want to react whether for example, they appeal for strict laws when it comes to knife of tax in germany. if there is no political motivation that go into and also determine how they move forward, so definitely closer to a decision of knowing exactly. so that is absolutely at the center of the current investigation and finding the perpetrator and determining the motive. but tell us more about this man hunt, which is being wide and outside the city is further up. normally what happens with these kinds of mine hunts as a focus 1st and foremost on the perfect other they move beyond the perimeter. they talked to i witnesses, they tried to talk some of the people who i enjoyed that try and put all the

different pieces of the puzzle together. there are also officials probably working behind the scenes trying to see if there were any cameras that's recorded any image that could be used for the investigation. and now the main task is to really put all that together and trying to form a picture that they can then present it to the public. but this something that takes time and that it requires a lot of people as well. so i can imagine that it's not just let's say local policeman or police officers in the building and working to try and find this out to be something that will require coordination between local, regional and national search. okay, so it is could well be a national operation. absolutely. okay. how much uh, or how often do things like this attack, these types of nice attacks and go from there to other countries? very rarely. so this is not something that really happens very often. nevertheless, it has been an increase in nice incidents in recent years in germany, which has led by the way, the interior minister to say that tied top knows, have to be discussed and debated on when it comes to possession of of knives. and

it's important to stress that we have to really be careful with these, the districts, because police and in general authorities have not been gathering statistics on this particular issue for a very long time. so experts have one that it's important to not basically conclude that business. a long trained however, in the last few years of police have recorded on increased so that's why there was also concerned about what is happening. now dw stuff is supposed to thank you very much for unpacking that story for us. ukraine is celebrating its 33rd independence day from the soviet union and presidents lot of mr. lansky moffatt day by signing of all the bands, the ross and linked orthodox church and ukraine. he also signed legislation on ukraine, ratifying the wrong statute, which allows the country to join the international criminal court. earlier he puts out this video address that he said was recorded in the border area from where keith launched its surprising persian into busha. let's listen to what he had to

say. i bet, sure nice whatever the enemy was bringing to our land has now returned to that home . and those who wanted to turn our land into the stuff is the thing about preventing backcountry from becoming a boss, etc. ration at the 1000000. the main building is also know what you crazy and retaliation is, you know, was a 3 symmetrical, long range is not the valuable. no, no, the sooner or later. yeah. can you do you crate in response or reach sadie point in the russian federation? this is a source from dying to, to our state and on people that when the demo. but it's well enough to allow them to turn our land into the graveyard, where the blue and yellow flag rightly belongs to the best zip code man from the red square. and who constantly samaritans everyone with the red button. it will not dictate any of his red lines to us, only ukraine and do crating the well the time, and how we live, what pots we take, and what choices we make, you know,

because this is having dependence. what i assume as i'll ask. ringback more let's cause i have a 2 dw correspondence on you found out and keep. so you tell us more about how you create as mounting is. so the independent stations ross has full scale invasion, a very powerful speech. the from, from the leader with been a, as in, as in previous years, a, the kind of celebration is a very new to them, you know, no public celebrations, north korean, so me to offense. and as in previous years, that of course concerns that i would have a heightened risk of russian attacks. both german and us officials have said there is an increased risk of russian rocket attacks, especially on the capital. keep around this holiday, we saw a kind of some dude event earlier today with presidents uminski. and along with the 1st lady, kind of lean flowers at the main memorial for portland, ukrainian soldiers here in keith that are

a few heads of state who are visiting cape today to, to mock independence said the president, pulling the problem. is this stuff? look away now on social media that are flooded for messages, but will lead to is, you know, kind of expressing support for ukraine on independence day and us residential might, and whose country is ukraine's main when a true reco has announced a new military aid package worth a $125000000.00 on the eve of ukraine's independence day. what is the situation right now in the front lines in east and ukraine to take us back to the ball of the will in the eastern don't yet so age and uh, the quote suggests that russian forces are kind of pressing on the all making study games that claim to have captured a few supplements in recent days they, they are closing in on the town of book adults, which is the major logistics hub for the ukranian ministry in the region. not blue cross is also located on the, on the intersection of a key road that is used to supply troops as well as the front line. so piece was

also to move casualties towards the city of ne pro and local authorities have now been urging across $40000.00 civilians to evacuate within the next 2 weeks before the situation was of families with children have already been ordered to leave. and, you know, perhaps has been a key target to most school for several months now. and i'm, let's see, the capture of the stone code, you know, kind of compromise the queen's defense of abilities and supplied with. i'm could bring rochelle, you know, closer to a state, the name of capturing the entire doing it switching has the cost offensive chains. at least how you can see this one and folding without surprise offensive has certainly boosted model and list of the mood to or off to months of you know, bad news and setbacks on the battery fields in, in recent days. we've also seen you create and carry out a series of successful strikes on, on use of boats on oil depots within rochelle,

which of old main to kind of degrade rushes of war effort. and this is only part of the strategy the presidency. lensky says, is, is about, you know, bringing the wall closer home to russia. so i think ordinary people, sure, uh, so can be, you know, watching what i'll be watching these events. but nothing much has really changed in terms of, you know, that all day me every little, it's that i'll do the russian attacks. fighting continues. it's in fact it's, it's intensified and the prospects and fees of, you know, a seemed remote at this point. the w sunday finally covers the light, is there from keith. thank you. well, as the painting impulses advanced deeper into vases, closed regions, ukrainian civilians living along the border of were expecting some respite. the russian troops attacking them with drones and not salary for the past 2 years now, farther away, which could mean fewer attacks inside you. quite. a correspondent economy visited the ukranian community near the russian frontier to see if the hope of increased

safety has been realized. last year, 2 women were sitting on that bench over their show head just by their feet and killed the basement, the site of driving around below peter with a man, it's hard to find a street without a story like visible home for the day. so if you want to, especially those are the changing rooms of the sports ground on a master police station, if we need to. it's hard to keep track of what happened in web yet. do you remember what happened yesterday the day before you familar? but when you've been through a 2030, even 40 times of, of, of what just lose track circle live in the wall, is that you might think flowerbeds be the last people's worries in a town like this is your, it's convinced that vital appeal is residents need something to look at, he says something that's not a ruin. but even in that gardening schoolwork is have to be mindful of unexpected

reactions. mr. a lot in the town to make it so long. the bushes they're all a mess. it's all because we barely get the tremors and the mowers out any more. they make the same sound as the head, drones. people hear them and panic. other times when it's a real attack, the noise from the lower it stops people hearing the incoming fire or whatever, you know with that incoming file doesn't have to be a direct kit just didn't often the bloss waive or piece of shrapnel use enough to do significant damage of the of the rates are respond runs, halt. there's information coming in from the military as well as from presidents close to the border. it's his job to keep everyone informed by the towns telegram channel on the some of the glad bomb has been spotted on the russian side of the border. we also had drones headed towards be the pedia. normally we might get a 42nd warning either it'll come in soon and explode,

or it will keep going. sometimes they change directions at the last moment. a little bit closer to the exit to better understand what's going on. so just just a minute ago, can i ask you next me i caught a message that 2 people google in do to, to civilians been going to buy the clock on explosions that we had just few minutes ago. a couple of columbus down the road was one person long injured. on the street . we arrive on this residential street for told that 2 wounded posts as boy for ready being taken to hospital. luckily these houses were empty. just a few meters further. the result would have been very different said he lives just next door is to ensure an angry the bomb came a knowing even baba to come around. so i was like to keep it would dead all relying

. they were just standing over the staring little crates of the month. do you get it? you get why i'm hungry up is that he tells us it's not that 1st close shave. it's 2 months ago. crap me. so i was hit the street and he's a little less optimistic that his towns man and his wife don't want to take another chance for you, the input from the for sure. what will you just get childs and think what to do next? don't know what's going to rebuild all this now, so it's definitely about a 5 years old shift a single door. we have to leave all the items are on the way somebody can use coming in right now. the u. a. e e says it's broke it, a prisoner exchange between russia and ukraine. the foreign ministry says the board nations have exchanged $230.00 prisoners in all $115.00 from each side. is the 1st such present as swaps in ukraine, long states, offensive into russia this month. and we'll bring you more details on that

developing story as they come in. let's look at some of the other stories making headlines from around the world. and explosion outside of synagogue and the french town of like, hallmark has injured a police officer, francis interior ministry, as described incident as a criminal act. and said police are looking for the public choices authority. so think the last to a nearby convict contained a gas canister. italy's public prosecutor has launched a manslaughter investigation into the depths of 7 people after luxury yacht sank off the coast of sicily, british tech tycoon mike lynch was among the victims. it'd been on board the cpr, named by ition with friends and families celebrating his recent acquittal in a full case. he rebels have released footage showing a shape on fire saying it shows a tank as they attacked a greek owned oil tank. it was struck thursday in the red sea before 29 of its crew

members were rescued. the hoodies had been targeting vessels in the busy shipping room since the board and gaza began last october, flooding his gills at least 13 people in bangladesh, forcing thousands more to flee from their homes. the disaster is an unwelcome challenge for an interim golf mental body under pressure saving. what is left of the belongings. monsoon rains across the east of bangladesh have displays thousands. the homes submerged under was a very severe damage facing the ponds. we watched out in the flood water, many houses are affected, all the roads are damaged despite that some has been able to get to shelters like these. but there are many more who need help to control the situation is really about to them. there's a lot of age,

but if we're not able to rescue those, we're stuck to what we give it to the bottle people will get released, but 1st they have to survive. we don't have boats here. i want all of us bangladesh to send us boats. we don't need more aid need boats so that we can save them like the buckeye, some blend the interim government for being slow to respond. nearly 5000000 bangladesh, these have been impacted. and more rain has been full cost in the coming days. written prospect for the many already facing the brunt of the flooding. and looking beyond the balance of us now far out into the depths of space wherever phenomena, known popularly as the blaze star which has appeared in the night sky. astronomers have been expecting the nova for months is what you need to know about this events that many experts a calling a once in a lifetime costa mesa car are usually the blaze star is too faint to be seen

with a naked eye, but around every 80 years it suddenly becomes one of the brightest and the night sky officially named t corona, bori. alice often shortened to tea cor, bore its what's called a recurrent nova astrophysicist. brad schafer has studied historical reports of earlier sightings, a. t for bore went off in the year. $1787.00 t core bore went off in the year 1866, and it went off in the year. 1946. and that works out to a $79.00 or 80 year rupture and cycle so roughly 80 years or 79 years after 1946 is round about now the explosion that we see isn't caused by just one star, but 2, around 3000 light years away. t cor bore is a binary star system,

made up of a dense hawk white doors, and a lighter cooler, red giant. the white door gravity constantly sucks material away from its larger neighbor. you have a close interacting binary star where one of the stars is relatively normal and you know, the other star was a white door there. so close the matter from the inner edge of the of the normal star falls under the white door. as the denser smaller star in the system draws mass off, it's much larger neighbor. it builds up steadily on the white door surface. when the pressure and temperature peak every 80 years, the below you start goes off, like a gigantic thermo nuclear weapon. and when the hydrogen fusion starts, it becomes a runaway reaction just like it and hydrogen bomb and all the whole surface blows up, just like a hydrogen bomb. and so you have this huge explosion on the surface which sends off

matter. and the star brightens because you're looking at an explosion to view the nova. look 1st for the constellation bow tase nearby, there's a small semi circular formation called the corona, borealis, or northern crown. just off at the returning blaze. star should be easy to spot. so let's see how easy it is. a reminder of our top story to sell police in germany searching for an attack of who killed at least 3 people at a crowd of festival. a governors were injured in the 9th attack and zoning in the waste of the country. according to witnesses, a mad stabs passes by, but of thirties of said, very little or anything balanced among and ukraine's president has pledge that most good. well no, what retribution is as keeps forces occupied connor process, cost screenshots, and video adress marking new paint. 33rd independence day, bloody mit soleski stated that while russia aims to destroy his country,

the war has in his words, returned to it's on the bridge you up to date on all the international news i've been physical and x one sec. the

a joy ride road guides know the way around is strictly scientific trip to some pretty cheap places. curiosity is we tried tomorrow today. next on d, w. this shadows these pod costs and video shed lights on the dog is devastating. colonial har is infected by germany across up, and he employed

a score, supposed farms and destroyed like what is the legacy of this wide spread race as depression today? history. we need to talk about here, the stories, shadows of german colonialism, living independent, arise to our society is full of contrasts and inequality is a big many problems can only be solved by working together. yes, i think i pretend as a new slaves and what is home how do we tackle the major issues about time to because there is a significant risk of human extinction from advancing our systems and changes to your frontier. so from our series continued

on september, 1st, on the w, the forest produced oxygen stole volta and regulate the climate. but not enough of a surface is covered by trees. just 30 percent. many forest have been cleared to provide phone land on climate change results that causing problems for woodland droughts, killing trees, and encouraging wildfires. in places like canada rushed to greece, brazil. this time on the show, we take a deep dive into the forest on this future. welcome to maurice today. november of 2023 and there's fire in the pond to now. 2 the flames devour trees in

the south american wetlands region. solange e k, to end our team, look on stricken as the inferno rages out of control. they just finished a re forestry project here. so they would read them for you play music. it took the planets life time to create the content now, and we're destroying it so quickly. it's terrible. it was more than that. the team was actually on the way to check up on one of their research fields. they were investigating whether the forest it started recovering from catastrophic fires 3 years ago, where there new trees were growing back. to think it is as a guy, what if we had more trees, it would lower the temperatures here. he gets from new trees, can grow in their shade because there are no protective trees anymore. the young plants dry out, so they move you to climate change is heating up the ground and without cooling, shade, a new generation of trees isn't growing. solange decatur says that that punch in

our a patient, it would be sick, is a who and me and via the river is my life. i've decided to dedicate my entire life to protecting it. and this is and this the punch. so now in western brazil is the world's largest inland wetlands. it's a unesco world heritage size. around half the size of germany, of the bio diversity in the region is done in this species that inhabited have adapted to a dry season, followed by flooding. and the rainy season water levels climb high above the rivers bags. and usa and george have always lived with this rhythm on the edge of the river during the floods, fish find plenty of food and reproduce. river residents,

both humans and animals live off that bounty all year round. but there are major changes on the horizon and they're worried afford is slated for construction here for shipping cargo like solely beans and cattle. the sabbath county where there's money to be made, things happen. unfortunately, that's just the way it is. interesting. brazil is the world's leading exporter of d at us on the quarter is proud to had one of the country's largest cattle farms for him using the river to promote businesses the right thing to do. after all, every country is looking for economic progress. it brings in foreign currency, which brings prosperity and we're heading forever. cattle company, land runs right up to the river, access to

a water route with slash transport costs for farmers here, speeding up the time it takes products to reach pacific ports and ship to the huge lucrative chinese market models. where is the once it opens up whole new perspectives, it's a sleeping tiger she goes and once it wakes up, everything will grow and to see good se salon shaqueta fears that more cattle and more soy will mean more deforestation and more heat the river levels are already alarmingly low, now they are digging to deepen its channel and it'll have to be dredged even more for a cargo ships to pass, but that will help natural flooding. she sense of pressure the moment. if the river is dredged out, the water will drain away like and it can now put at the heartbeat, the pulse of evan. flo will out here. if we lose these wetlands, it will be a tragedy for brazil and the whole world to one of these. then there are the forest

fires, the region so more and november 2023 than any previous november on record. and due to and george are frightened, the flames are getting closer. sometimes they're just meters away. that it was possible was seeing all the birds, all the animals dying on the whole thing. and there's nothing you can do up to the couple. we'll send for the 1st month, it breaks your heart. i want to talk, where is the key? you entered this bed and news that has been collecting seeds for so long as you k to entertain for 3 years, enabling the scientists to replant important tropical trees. today the fisher woman receives a sibling as a thank you. but only one thing can save that punter now. yeah, well this reforestation on a massive scale reforestation projects

in the european union making strides forward. but at the same time, climate change as having this, the impact on existing tree populations. many species are unable to cope with the rising temperatures and per long droughts. that according more common by the, on the changes on totally affecting money as far as money coaches in germany, researches and experts of thinking about how to make the country as far as fit for the future. in the densely wooded south west of germany and the state of rhineland, polite and at almost 9 and 10 trees over hill forest are fleet please hang on. this has been monitoring the condition of the woods here for 30 years on schools is on. we're very worried about our for it, so it's like a fever occurs when a fever rises, it doesn't mean a patient is dying about. it's an alarm signal, and we have to make sure it doesn't get worse, that we do everything we can to help the patients who is good. so where did the

experts take measurements once a year clean to these angles and his colleagues look at the health of the trees in the same $167.00 locations. and 15 of them like in this national park, there's no longer anything to check and those who on so many of the points where we used to take measurements are now stripped to say here, there are no trees left. something we'd never seen before in our, for us to condition saturday is unprecedented. opportunities were very concerned that the stance have disappeared over such large areas and it's making itself cells . and we really noticed that in our sampling grad who of us the, the main problem is the bark beetle, which is spreading rapidly due to dry conditions. the insect has already killed many spruce, and many trees that still look healthy are already infested and will soon die.

although the tiny holes they make are barely visible, the beatles and their young drain trees of water. around 20 years ago, spruce is made up around a 3rd of all trees in ryan lunch. but a lot. today, the red under 18 percent numbers continue to fall. the proportion of beach and oak is growing, but they're suffering too. so when is a tree considered sick? exports to assess the condition of its crown and how dense its leaves grow. what do the leaves or needles look like? are they green or do they have brown spots? we do is showing that it's can tell at a glance and the appointment. there are individual trees that we've been observing for years, which can survive unless something else bad comes a lot like a bark. the lender approves or cast 7 fast h as in dogs. if that doesn't happen,

well tree may well live for quite a few years and so they can also recover. a typical example for that as b o, which retains a high capacity for re generation even if it experiences heavy leap long enough to once a boom hot of the forest here has been hit hard by dry spells in recent years. and pollution has also taken a toll nitrogen and sulfur oxides. enter the soil through precipitation. acid, rain and forest di back have been issues since the 19 eighties and it was on the acid rain so itself or dioxide cause the soil to grow acidic because i want a few alkaline elements and there are destroyed by those acids. claim animals were 2 and the bases were washed down, making a bad situation. one is with the for shelves. what could the forest of the future look like here? douglas, far as now often planted instead of spruce. it was stands, drought better grows quickly, and there's

a market for its wood. but it says no single tree or solution can save the forest. us kind of fall off. for con, every 3 species has some kind of problem, but some things are important is bundled. first, you have to select species that are suitable for locations. ones that can cope with a soil and the climate. and then there's planting a mix of species, but you shouldn't plant as many trees as possible and ensure that there are at least 3 or 4 different species in the maxima, swanson, for sweet place ngos and others making german forests fit for the future will be an ongoing challenge in the years to come in kenya, a lot of trees will cut down for charco production over the years. about reforestation projects are in full swing, an effort to replace some of what's been lost,

researches, rules and monitoring conditions and wooded areas without official intelligence, the relying on goods to supply them with key ecological information and samuel goods. you is looking for birds, the ornithologist for 10 years national museums, pets to the field with his usual tools, but not killers of finally 2 deer and lots of patients. so, white ground grubbing chat, see it's, it's can have it color. yeah. but samuel is not just here for a walk in the woods, he's helping to collect data for the forest sensors. he looks for species that can

help identify threats to the eco system. today, he hopes to find a bird called park labs to rocco. so buds like those uh for us the dependent clause, the new rely on indigenous for assistance for the food and breeding and foraging areas. so when we lose speeches like the hot cloud storage, cool, we know that the for us health is in decline and may be, will indicate that we need to do something about that in terms of maybe reduce into fear around. so plant more indigenous fruiting trees in the area. but this data collection method takes a long time, spectacled weaver, when that's calling true. but when it comes to deciphering bird calls, even professionals make mistakes. luckily, a local university has developed a device that can help researchers like samuel. okay,

so this is an acoustic sense. i'm not to be developed on this into for an adjustment and addition diligence. all right, for i would do data collection with the goal of $20000.00 ecosystems using so we have a solid bundle decides to buy cheap. mm hm. samuel is excited about this invention . he believes that can help him and his work the machine learning powers. the technology, as well as most artificial intelligence, recorded audio is converted into visualized data, which has been analyzed and used to teach the system to recognize bird calls and other acoustic markers. this data can be very useful when it comes to environmental decision making when it comes to equal the system such as far as the beds, uh good indicator of the forest health. hey,

i tools can help quickly determine whether a hardship you go. systems need help. for example, in the form of reforestation. like here where more than 30000 indigenous trees weren't planted and a habitat degraded by charcoal production and agricultural encroachment. the trees are monitored and tracked over time, the but manual monitoring is time consuming. so this scientist use is a special tool and a high powered stereos go and look up to a dream. it is of trees. and it is possible for me to images to sort of acquired the depth of the points on the scene, you know, just know how far the buttons, the, how to the out of the ground, the inside thing. so it gives us sort of a 3 dimensional understanding of the scene in front of the coming of the software called tree vision. automatically measures tree height, width and other features. the data collected can be used to project the amount of

carbon that can be stored by a growing patch of forest, just like the designs for that file. acoustic microphone tree vision software is open source. so other researchers across africa and beyond can freely adapt it to help keep ecosystems intact. the trees can be found practically everywhere on this, and they come in many different shapes and sizes. there's a huge range of species on scientists still have a long way to go to identifying them all of the mold and $73000.00 trees. species that are thought to exist on estimated $9000.00 have yet to be discovered or described. not so the bread and not treat it secret for revealed long ago. columbia is tropical drive for us, cuz home to many unique animals is why motto is also known as i'm on the

home page. the bread? no, it's for maya not tree. it's thought that it's seeds played an important dietary role for the ancient maya. it's found in central america is dr. forest areas for colombians like heavy jose is a key to it's an old acquaintance in any escalade that will make it well. i've known it ever since i was a child to the property. that is when my grand father took us home with him, he taught us a lot about the g y model is nutritional and physiological aspects of we children ate them. we harvested the nuts wild in the forest and ate them raw or cooked. yes, they nourished us even as a child, i knew many ways to prepare them. now i know that the tree has even more great properties, so it has even more value for me that the model of the wind model seeds are harvested with the help of the animals that live in and feed on the tree. it's

considered an umbrella species as it contributes to the survival of numerous other species in the same habitat, the double 0, san francisco bounds pod that contains the not that lift gate will say the pod. well, that's not the see. this was the batch drops out along with some birds that are available. we gather them up from the great the take them home is a wash and sort them and lead them to dry. after a few days, maybe $15.00 to $22.00 of them depending on the weather. seeds of dried fema is the sick. in the town of a v hoss in northern columbia. why motto seeds from the monkey is deemed by the are turned into flour and a processing plant set up by a colombian french, and geo called envoys them. its goal is to sustainably use non timber forest resources. so those that don't require filling trees. like the g y model

receipts that that was the end of that time here. they're moved and shaken because the seeds are covered by his skin, even after they've been dried completely. then they're processed further and roasted ground and packaged. we then send the end product to bo, go, tom. yeah, you can consume it as a supervisor, then anything you want, you can put it in the mail in rice and sweets and bread and thousands of recipes just as you like, nickel 2nd, to get us from the jungle to the table. that's the motto at this gordon, a restaurant and the colombian capital chef on twin. the other youth has discovered that why motto flower can be a versa tile ingredients in practically any dish with quite a bit. that's a very universal products because it's a ground powder 11 plus you can use it as a kind of coding. for example,

by not today i mixed it with you to make the dough from my end panata. it's very, very easy to use and it has a really special taste one that's unfamiliar dealing with our wi fi. i think it's almost never use this one despite the fact that it's silver's a tile sad because the flower can be used in many different ways, particularly not the most of my native. the wind motto is very arrow matic. with a smell similar to coffee sentiment, nutmeg for chocolate. so it's ideal for ice cream. is not it is, it's like a spectrum. we've been in power ice cream recipe seems to emphasize the special flavor of united way and get into it helps us introduce it to people who may have no idea what, why motto is fatal. so they get to know it for the 1st time. and then of course, that's the one of the variance. collaboration with a scientific community is important to ensure that guests appreciate the novel

product those as doyle, in nutritional terms, the seems that the bread no tree are really packed with healthy components. studies have looked at that as well said enough to put forth the results show that it really is a kind of super for me. and we want to share that realization with everyone that meant that going by the date of the month at the alex on to fund humble, biological resources, research institute and via the day of a monica flores is doing in depth to work on quite a model. she studies meds, tales and legends about the tree in indigenous communities, as well as it's nutritional value and many uses. the growing motto is a member of the motor see a family plans that are characterized by the fact that their lease produced a milky sap called latex dinner. but it's also think that it's on this call may say not. the plan also has some additional properties except for that the latex can be

used as an hour and for some wounds. and let this come in. if the lease i'll come on, it's also used to cleanse. the stomach raises the less blunt domestic in the rush room. why motto seedlings are used to treat your illogical conditions and to purify the blood. so i'm going to get to the phone today. over 40 percent of the seed by weight is protein. it also contains a lot of iron and healthy omega fatty acid. this gives it great potential as a products that can help ensure food security. also, a lot of blood flowed with one stone. the single tree can bear a lot of fruit and one season. this is that you can even substituted for me or other proteins, and it can be a food source for a very large population. a single tree can feed a lot of people into for me, therefore, it's a super for us. for that event. the seeds are not only strengthening the economy in

rural areas like over the highs, but also highlighting the importance of columbia's tropical dry forest. an eco system under threat from agriculture and live stock farming. the enormous roots of the guanajuato tree grow very deep, so which resistance of both drought and fire making it an ally and the fight against mel nutrition in an era of climate change. or if i was let is read, why? now it's your 10 go to science question, then send it to us as a video, text or voice mail. if we answer it on the show, we'll send you a little surprise. it's a thank you. so go on. just ask this question came from you'd be in gun in the why is the length of a year and different on every planet a. ready ready orbit,

our son may do so in more or less elliptical orbit. most places on earth we experience a year through the course of this. only around the equator does weather remain largely the same all year round. and astronaut nicole terms a year is the period of time it takes for a planet to complete a single orbit around the song on earth. that's 365 terrestrial days. this has to do with our distance from the sun. it's so far away that our planet has to travel 940000000 kilometers to complete one orbit. vast in size compared to the planets, the sun exerts enormous gravity to remain in a stable orbit. the earth must circle it at a very specific speed. 30 kilometers per 2nd. if our planet moved any slower, it would get closer to our star,

the if it went faster, it would drift further and further away. the duration of the year therefore, depends on how far away from the sun planet orbit as well as its speed. the closest of the day to the sun is mercury. it's orbit as much smaller than that of ours. because it's so close, the a sense of the sun's gravity are greater there. mercury must orbit the sun faster to stay on track. it therefore covers less distance at a higher speed. a year on mercury only lasts $88.00 or states. the farther away a planet is from this on the longer its orbit and the slower speed it might sound hard to believe. but a year on the outermost planet. net to last for almost 165 of hard years
