cetera surprised the events both girls and boys after tournament on saturday, he stopped in for a quick hello and group photo session. he then grabbed the smartphone himself for a series of shots, telling the kids to say swiss cheese before he went to switzerland's. finest experts said thanks and farewell we do that other. all right, well that's all for now. doc film is up next with a look at an at advancements in forensic science and remember you can get your news around the clock on our website on dw dot com and of course follows on our social media accounts. i'm pablo fo lillius remain the team here in berlin. thanks for watching. take care. i'll see again at the top. the next are the green, and then you feel worried about the planet me to on the old hosting the on the green fence podcast. and to me it's clear remains to trade.

join me for a deep dive into the green transformation for me, for you, for the plant. ah, ah, the essence to solving crimes is evidence. i'm fishing. if i didn't even the perfect medicine, you always take something wiki. will you leave something behind you? it's new forensic methods and making the invisible, visible most trace evidence comes from nature dis, a mind to soil in the palm of my hand contains more individual organisms than there are a number of people that live on this whole planet. but there remains much to discover

open questions to answer technologies to develop collect his geometry. question is, how long has these trace been here? did you only when i know that can i link it to the well as yield? time is also relevant in other investigations. often if i'm hoping that we can say, for instance, this pew perry, i'm is 2 to 2 and a half years old or this pu perry. i'm is 8 weeks old woman. i will the perfect crime soon. be a thing of the past. ah ah,

lulu. every flowering plant produces it. it wafts through the air, often invisibly, attaching itself to everything that moves. pollen leaves its mark everywhere and can even help solve crimes lose the sail wolves surrounding each individual grain is so stable that poland can survive millions of years. vienna, the austrian capital, is home to thee expert in the field of forensic pollen analysis. martina vega, heads the department of structural and functional botany at the university of vienna. she's one of a few scientists world wide working in the field of forensic pollen analysis.

on a sunny day in may in low austria road workers working in the helen towel, a popular tourist destination near vienna made a discovery that starkly contrasted with their a dealing surroundings. they found a corpse lying in a roadside ditch the criminal investigation department of the state of low austria launched immediate investigations to lasha. and i think the body was wrapped in a blanket. and yet it was immediately clear that there had been a violent crime. so we took up the investigation for the crime scene and homicide teams from the states criminal investigation department drove out to her and talked and we were quite certain that the location where the body was found was not where the crime had been committed with mister todd of the investigators soon

turned to martina vega. civil didn't have i'm in, i'm thinking the dead man was wrapped in a blanket on the it most likely came from the primary crime scene or at least from the perpetrators. what if, and that's why we examined this blanket thoroughly, did come with him, of course, because you can't wash the whole thing. but you can't small pieces out of where there is no to go clumping. or why you suspect them might be something interesting underneath it of the think that is that is that of the football and after washing the sample, it's centrifuge to separate it into its component parts. paula knology is the scientific term for poland analysis. the study of scattered dust.

oh, the 1st person world wide to solve a murder case with the help of forensic pathology was vill him klaus martina weber's mentor. here at the university of vienna, at time, the suspect had the whole of vienna on tenterhooks, because the murder victim could not be found in love at 1st thing over the course of a year. he hath named a wide variety of places in the vienna region yet, but nothing was discovered until professor wilhelm klaus showed up out this. he was a police botanist here at the university of vienna voc, under biologist, by training there have to make he had the brilliant idea of testing the suspects. shoes and clothing fits all. pollen of poor, noticeable flu. among the thousands of pullin samples, professor klaus found was fossilized hickory pollen from alone,

extinct species. that once grew near what is now the village of spillane in low austria. confronted with these, finding the suspect confessed, and revealed the bodies exact location to day, many know about dna traces and how to avoid leaving them. the criminals too, but poland traces i everywhere and are extremely persistent. ah, martina vba is working on a case that dates back almost 2000 years. it's not a crime case, but rather the scene of a natural disaster. she's attempting to correct a possible historical error. when the volcano vesuvius erupted, it completely buried the ancient city of pompei, the ash preserved the city,

and many of its inhabitants in the last seconds of their lines. the eruption date of august 2479, c. e derives from the letters of pliny, but other writings and findings suggest that the eruption did not occur until october 2 investigate this discrepancy samples were taken from the nostrils of some of the victims. martina vega is now examining them to determine from the inhaled pullin. what season the samples are from free flying, poland gets caught in the estimated bone, the bone at the end of the nasal cavity. it usually stays there for about 40 minutes before it is exhaled back out through the nose. by examining residual pollen on a corpse as f moines bone, conclusions can be drawn about the last 40 minutes of that person's life.

there are 4 samples to examine the poland from the nostrils, a centrifuge, and then boiled in a mixture of acetic acid and high dried and sulphuric acid. this process removes everything but the pollen wool, martina they, but then begins the counting process under the light microscope. gradually she determines which pollen grains are represented in the sample and in what frequency they occur. based on the microscope count, a so called pullin diagram is created was the here theme is the what we have here is the sample from a child has gone that i specifically from the nasal, based on we examined the material to soon discover the diverse array of plans have

trans crowns, which indeed grew in pompei like in pine all around the al if trees then autumn easier than after. and there was also a, hey, dora, he likes pollen grain, he'll rather loads of them with a. so if he did the fans, ivy is ivy pollen. if i fi, fi tends to now and later in the year, ah, oh, this vast amounts of course was relevant to our research question of whether we can ascertain if the volcano really erupted on august 24th, or much nature in the year. no cost. i'll get broken. is there a big debate on the matter crossing his console and should the eruption date of mount vesuvius on the 24th of august 79. c. e. be moved to the flowering period of ivy. in the autumn, it would be a sensation if the date of this world historical event would it be changed on the basis of a pollen examination? the whole entire case has not yet been solved either. the tests for pulling on the

woollen blanket a still in progress barely visible to the naked eye and yet so rich in information. the pollen grains swelling from flower to flower have breezed into the ranks of forensic methods. but they are not alone with its unique profile, the soil in which the plants grow is also valued in investigations. aah, luna dawson is one of the world's leading experts in the field of soil forensics. she's consulted by police departments from all over the world. ah. this, the mind to soil in the palm of my hand contains more individual organisms living together. then there are the number of people that live on this whole planet. so

just imagine how many that really is this is teeming with life. and that information can tell us so much about the soil, that is the home for these multiple organisms. the micro organisms in the soil are responsible for its structure and fertility. they break down toxins, help plants absorb nutrients and contribute to their resilience. but can soil also bear witness to a crime? galloway forest park in southwest scotland is the largest contiguous forest in the united kingdom. tourists and hike as are attracted by the unspoiled natural environment with its diverse animal and plant populations. but on june 12

2019 walk has encountered more than pristine nature. hidden beneath some branches in a hollow in the earth, they discovered a corpse investigate as quickly established that it was a woman who had been missing for weeks, and that the cause of death was unnatural. they soon had a suspect. police sent several soil samples to lorna dawson for analysis. the scientist compared the soil samples from where the body was found with samples collected from the suspect surroundings. there's a whole range of different methods that can be used to can ties the sole biology and the still a lot of the search to be done to make sure that and when you're competing ah,

unknown sample with a known sample. and that the same procedure is carried out, cuz that's absolutely vitally important, that the any analysis is carried out on a, on no one a question sample. you have to use the same procedure for any reference sample, it's going to be compared to it. what about the soil samples in the current murder investigation? could lorna dawson helped to solve the case in the investigation? the disappearance of emma folds. the police sent us a suspect pair of timberland and i was asked to examine them and to determine from the examination. what type of soil that was and any vegetation within it, what clues that could give us to where that person had stood or had walked wearing those those shoes or boots. in this case,

i technologies an analytical methods are constantly evolving, ever smaller samples of thighs for investigations. microscopic soil residue on shoes can betray where a person has been. even tiny organisms can provide important information at frankfurt institute of forensic medicine, entomologist yes. amens works with some of them. the wilsons in forensics, we use insects, and especially flies, to clarify questions about the victims time of death because the traditional forensic procedures only work well one to 2 days after that and yet. so in that window, you can estimate quite well when exactly the person died. storm is,

but after that, there are no reliable forensic methods gift. however, if insects have developed on the corpses usually fly maggot license, then we can use these to figure out the minimal amount of time the person has been dead for minch ministers from tools. the 1st step is to determine the species on the corpse. then the developmental stage of each species is examined, flies live on average about 3 weeks. and within that time lay several 100 eggs. the maggots hatch off to 12 to 25 hours. the lovell and pupil stages each last about 10 days. mm hm. out of i as a function to formally forensic entomology works relatively well to the exact day in the 1st 3 to 4 weeks after colonization of all. that's how long it takes for the adult fly to hatch. having passed through the egg, maggot and pupil stages of 3 to 4 weeks approximately this week, and after that accuracy is pretty much impossible. i mean,

it wasn't like and so we're hoping that the analysis, the chemical analysis of these empty view area will allow us to narrow down the time period beyond that point. by now several weeks, several months, maybe even several years. may i am worn out the feel i forgot me? of a yog, the pupil casing the so called p peria canal for further clues. one in 5165, and our forensic work we're trying to determine if the weathering of the pew peria is the shells that remain indefinitely intact at the site where the corpse was found. if the weathering can be quantified on the english of defer veto, that's where the cute secular hydrocarbons come in. if it a corner of a social, the shells contain specific hydrocarbon chains. that is, when buses off, we believe that over the course of time they break down the lay, decompose from long chains into increasingly shorter chains separation. so follow him of course. so the analysis helps determine what hydrocarbon structures are

actually still present in the cuticle for the an elusive, efficient busing doesn't. i hits for we can reconstruct temporal processes. that is we can work out how long has this pu perry. i'm actually been lying here at the site where the corpse was found. i need to hear life and foot on the surface of all insects. there are organic chemical compounds composed of carbon and hydrogen. traces of these so called q tequila. hydrocarbons can also be found in the pew peria and are analyzed in the gas chromatograph his law with i believe that with the help of these 2 peria, we can narrow down time periods that lie in the range of months or years on this of i'm hoping that we can say, for instance, this pu perry, i'm is 2 to 2 and a half years old or this pew perry. i'm is 8 weeks old. of the research is still in the developmental phase, but yes,

i'm in his confident that they'll be able to apply the new analyses soon as was ongoing myna. what special about my work as a forensic entomologist is that i get to link basic research to it's immediate implementation next year in of us as a squish a. so i can start an experiment to answer a fundamental question and a concert, and that answer in turn helps my work on cases at the institute ish mint on an provides the answers, the police and prosecution ne auto body plates high for me. that's the biggest incentive from and the fun of it that goes to unclipped my glasses pasta by noon. it's exactly the spirit of innovation, curiosity and broad scientific interest that so indispensable in the forensic disciplines. because often there is more than one way to solve a problem. to get results, you have to use your imagination, be open for new perspectives and always have one eye on the latest research developments. and what about the investigations into the eruption of mount vesuvius?

worthy ivy flowers martina vega found the evidence for a later eruption date damn says in fact the she found it in the 2 children nicholas norfolk but not in the year out iceland. where was the single pollen grain there i think and not in the reference sample. hi, veronica. there was significantly less bab and in the children's noses. yeah. then you have to think it was missing. what do i do with it? now the me with these results this month, bye was he's i, there are 2 problem is even this is more than one is just that, that it was only found in the children of skulls exist the if i the 2nd is that hater a helix, the ivy is an insect pollinated clam before it's pollen and doesn't just lie around it on its own beside which means that the pole and must have somehow actively entered the nostril. seattle, bashful sadly dismal, took the explanation in the end. it was that in from past time in the flower beds

were preserved in oil o wines. youngster and a medicine was produced from its which was tripped into the nose as if children with respiratory problems seen outside in, within kingdom. i often wish we hadn't, and not only apple and spectrum was making a lot of sandwich. spectrum guns facing there was poland in the children's skulls in not in the adults square and all so significantly less in the reference sample. if you can't vedic and that if it's proven so for the time being the eruption of vesuvius in 79, c, e remain stated to august the 24th. it's not enough to find the traces. they must also be considered in an interdisciplinary way. because without the knowledge that at that time, the pullin was also processed. in other substances, the avi trace would have led to false interpretations for martina vba. this was an interesting excursion into history, but it's time to return to the present the clarification of the whole entire

case in austria is making slow progress. tomantino. mm hm. mm hm. and we've worked with martina vba on a number of cases in the past. and in this case to where we didn't know where the crime was committed, we started by doing a pollen examination on the items found with the body point, the blanket, for example, and the victim shoes authorization. the idea being to determine which regional, where these items could have come from of eva from and martina verba from the university of vienna has already helped us with some cases in the passcode based on the pollen structure. and she could tell the broad region the individual came from always staying in and what distinctive flowers plans trees would be found. growing in that area. ward, these epistle here come to levels in new york gone. what will the pollen trace analysis from the roadside bodies blanket reveal.

another tool for revealing and understanding evidence is bloodstain pattern analysis. it's used in investigations, especially when blood stains found at crime scenes do not match the suspects version of events which punish itself causing crime scenes where there's a lot of blood we will focus on the blood stain. very often, the perpetrators will often say, so i only hit one source in the heat of the moment. oh whatever, a crime of passion it was, and the bloodstain pattern shows a completely different story, a different picture, and others. it means that we can disprove that. it was one blow that fell in the heat of the moment because in reality there were 15 blows and they were not from the from to, from behind on. so blood stain analysis can tell us a lot about the nature of the crimes, but by the blood stained patent wouldn't how the rule of all southern the french mediterranean metropolis of marseilles is the location of

a forensic laboratory run by one of the most innovative experts in bloodstains phillipe esperanza, people from all over france and other countries to cool on his expertise the analysis of blood stain patterns can provide important information for crime reconstruction by examining and interpreting distribution patterns. forensic scientists can estimate the location time and intensity of violent actions than the one that is it has the ssl. so the, the analysis of bloodstain is, is based on the description of what you see in this case. and that is primarily the shape of the size and the dispersion of the blood stains. that is where they have found their location, who are the different services they have found on will again and their distribution

leave you? how are they arranged in relation to one another lease, or they convergence as can, while they distributed in a linear pattern? it's one of these other fold principal aspects in identifying bloodstained patterns . you don't, she then modelled because this'll mm. they're aluminum based chemical agents that can detect traces of blood that have been wiped away when applied to surfaces that have had blood on them. the ion in the blood acts as a catalyst for the oxidation reaction. in the dark, the bloodstained glows blue and can be photographically documented. conventional agents however, destroy the dna. in the stains leap, esperanza has developed a recipe to preserve the blood dna. his re, agent bluestar, is applied in a case in nor see a man is suspected of having killed his girlfriend. while searching his apartment,

the police found traces of blood in the bathroom and the bedroom. the boyfriend had wiped it away. but he wasn't thorough enough. it turned out once felipe esperanza began his work. looking at the photos he was sent of the alleged crime scene, he found an interesting pattern of stains on the wall in the bedroom. one or 2 small and much like either on the to front of the new jeter it don't. over here we can see the mattress and the nightstand. and behind them on the wall we can see patterns. little dot shaped ones made some bigger, some smaller. but they aren't those massive stains in which you can recognize the sponge or more trace this for to the form. and this is where it gets interesting, more limited as kristina your costs on to because while all other traces have clearly been cleaned up for these poverty form ones have not. this is kim affair.

alicia lawyer if reduced. oh, i drove to the suspects house to have a closer look at that wound victim you. i found many stains that had not been cleaned up at all to class because there was so tiny you need to put and on a dark surface barely visible at all. may you show me me think she orange off a symbol one would have to actively look to notice the actually the hopper from of visit using blue star though you can we could see them on wanted it also some catastrophic mortgage im cavalier chevy crew. so traces that have not been wiped away show the actual distribution pattern of blood during a crime even better. the puts it was not. upon analyzing the stains, we realized that they all converged to a point directly over this mattress report, which her daughter, lockscreen believe. therefore, there must have been some kind of below that caused a wound to show the impact caused the blood from the wound to spray in all

directions. originating from that one points, often called last cornea again, but even to school that she's able to point to official diploma pounding disc. we're talking about a convergent distribution limit. no, this is the type of pattern i found on the wall. but after the 1st or 2nd blow, it looks blood will also stick to the weapon. and when you move that, the centrifugal force will create a more scattered pattern. but here in this case, law isn't distributed, convergent leave it on, but follows the weapons movement. a small object cycle this former was a lot on imagine having water on your hands and moving it like this. but then water will fly away from your hand and distribute itself in accordance with the centrifugal force, the blood. so you can follow the movement by looking at the drops on the wall if you're, if you want the bucklin and fossil knock on a lymphoma. so we have the same shape and in, within the range of a few millimeters. same size of the traces, like you have

a thumb oval made on the circular, and will, should on impact their distribution is convergent booth. where is why movement if i saw it, is linear and that's exactly what we had between events and the door, pull it up. in this case, esperanza analysis provides the necessary proof. well, no changes in wooster don't juggle. in this case. we use blue star firstly to confirm that the cleaning in question was actually the cleaning of blood pressure. so and secondly, that the blood belonged to the missing lady line or suppose in portland. well, these are the questions that need answering and such a case that live. so the gentleman is cleaning on it, but what is it clean all makes it a new shot. in the meantime, old a french calais services used blue star exclusively or false. the other aluminum based products are no longer used to be created. michelle is on today. a genetic analysis is systematically carried out on all stains, so it's good systematic, more in vo. clearly the unity extra positive test for blood is not the end of the

investigation. it by the actual dna test automatically follows jacqueline in magnolia village if you wanted it eats unambiguously the missing nurses blood. the blood stained patton suggests that the victim was basin while lying on the mattress. the blood spatter distribution leads esperanza to conclude that whoever did the beating must have been standing over the victim between the bed and the entrance door to the room. ah, combined with other evidence, esperanza investigation leads to the conviction of the perpetrator. the expert can be satisfied with his work for now, but there is room for improvement in forensic methods. one question in particular, concerns him a kiss to the question of

wendy long on you found my client's fingerprint on genetic to their genetic fingerprint mac. yes. but who's to say it wasn't there before? the fact it don't like so to link evidence to the crime. the question we now have to answer is that since, when has this particular stain been on the instrument, just feel on what day was left on the exact day of the crime and not a month before or after. then who knows for sure, i'm world wide. there are several teams focusing on this issue. we have to find a solution minimum of a definitive, a follow up proven sorta. sure. mm. international collaboration among forensic scientists plays an important role in so ling crimes and making lights safer in the process. ah, at the james hutton institute in aberdeen, scotland, lorna dawson works on the galloway forest case. the soil sample from the suspect

shoe was already in the lab for testing. as were other samples that had since been retrieved. some were recovered from the suspects comp. luna dawson was able to compare them with the reference samples in scotland. soil forensics is an integral part of investigations, but that's not yet standard internationally. increasingly, all over that, like great britain is used and it's considered to be used by the investigating authorities and overseas. there are more countries now considering and adopting sol forensics within their portfolio, all of methods that can be used a few years ago. i trained ups some students from brazil and they then went back to their own country. and now they've set up a so forensic lab. so it's really nice to see that this transfer of an knowledge

from one nation to another. to get the clearest possible picture, when analyzing soil samples, several different aspects are considered if the samples from the suspect and those from the location where the body was found, had the same origin, is an indication that the suspect was at that location. the soil samples are primarily tested for 2 compounds, elkins and alcohols. so when will the cat and soils pierce oils from a questioned item and from a crime scene? let's see. we extract the carbon compounds the compounds. it will occur primarily our al, ken's, and alcohols. here we've got a trace of the how kintrail file. i'll keane's being compounds are composed of both carbon and hydrogen. and here we can see, for example,

c 27. that means such $27.00 carbon atoms in that molecule and the blue trace, the upper line here, that blue trace is from the sample that came from the foot, where the yellow green trace beneath it is the sample that came from the crime scene. adjacent to where the victim's body was found. and as you can see, then retention time on the gas chromatograph. you can see at 27 and c l 20 t 9, c 31 and c 33. it peak said that in the same place they're the same compounds, and the height of these peaks are the same. so from that, we can conclude that there is the same profile with the same amounts and same relative amounts of the different carbon compounds. in the question sample and the

sample that was recovered from the kind see so the samples from where the body was found matched those from the souls of the suspects shoes. the suspect can now be clearly linked to the secondary crime scene. it's suspected that he dumped the body there walked away from the side, got into his car and drove away. more. luna dawson presented her findings on the woman's murder case at court. her expert opinion and those from other areas lead to the perpetrators conviction. often forensic experts don't learn the full circumstances of the case until after the investigation is complete. although we stay objective and try not to get involved the tall in the actual frame itself, in terms of the families involved, that's not the duty or the rule of any forensic scientist,

but one always has to have compassion and m. confidentiality is absolutely key. but once a case has been tried and am you, they're not aware and more fully of the whole case circumstances. and it really does hit home the, the need, the need to provide as much evidence, object of evidence that can help that court make the right decision. and, and, and bring some closure for the families that are involved in these sometimes very difficult situations, but equally well to all so, but you save it and that avoids the situation where someone is falsely accused of a crime. so that's why it's important that the evidence stands on its own and, and, and is available to both prosecution and defense. but the use of soil

analysis is not limited to crimes against humans. it can of course, also help to uncover environmental crimes or to relate agricultural performance to soil biological properties and also to assess climate change and identify hazards of soil, erosion and complexion that much more in the past, biology and botany related research fields did not have much of a say in forensic science. however, with evolving technologies and methods, more and more natural science disciplines are being used in forensics, dna analyses and now commonplace. but interdisciplinary thinking and structural networking are also fundamental. with

martina vba has a unique digital collection of pollen grains. in order to unambiguously identify poland from all over the world, she and her colleagues at the botanical institute at the university of vienna, a building, an internationally accessible poland database. pal dat is the world's largest polena logical database. weber's goal is to make the entire data collection from multitudes of plant families publicly accessible either from was had thick, thick, fletcher thus had empty in poland, date or in the various rooms, often fall under. originally, we just wanted a database that we could use to share info with each other. this is of us of what that pretty seen in the world, so to speak, with crying out the more for a free database. or that we set back up and put it online behind the online cache. it really only makes sense if you work together, men of it that don't know if everyone sits on their own data, then no one benefit regarding the full almost $4500.00 pound

species in their pollen are already catalogued in the database. and in the case of the whole entire victim in the blanket, the pollen provides clear clues. most criminals won't even be conscious of leaving the kind of traces that martina vba is working with and invoking after a few weeks due to a confidential temperament. we received information on the individuals acquaintances and on a possible suspect or several suspects. well, community to because we then started to investigate on monitor these persons to go to who are from the police, have 3 suspects inside and suspect that the crime took place in one of their apartments. but how can they prove the crime or prove that the victim was even present at the suspected crime scene?

battle has the very bottom we can see the sample from the crime scene. boardman m f is, was in. i taken a detached house. oh, and you can see that fine, precisely these don't again. oh and again in large quantities as it is of brown, mrs. brown bar, please, the cypress trees. this is of tool. you can imagine i feeders and the like, which is, i mean what i'm giving you errors in australia. there was a window in the garden and popular model so asked out and a variety of other plants, dandelions, and the license if she wants to be lower than sun safety. there is no doubt at all that these pollen grains came from the primary crime scene. toddler, and when we also found it on the victim, hugh, we could say for certain that the veins him actively made his way to the crime scene. sailor and all saying that the perpetrators roused him on the crime scene, otto and creaky tom the poland diagrams and the traces from the house. and from the blanket paint

a clear picture martina vba was able to prove that the trace patterns from the woolen blanket and the suspects attic matched lead investigator hannah's ferna. very much appreciate the cooperation with the scientists and wishes to create stronger networks, both nationally and internationally. the arbiten, i'm expe upton, we cooperate with as many experts as possible in the field of forensic center give you 6. but these are open to all kinds of investigations. you either reply or give us wookey we are really trying to link up internationally, but are always on the lookout in our new contact. so i can because of course, there are different kinds of expertise in other countries likes. we are can give you more details on there for police, have different experiences of duties, thompson. so when the case requires it, we can fall back on these acts, but yes, and that's only possible through international network anchor. it doesn't really work any other way from to notice that victory.

palin ologist martina vega will continue to develop the legacy of her predecessor, is a bit of, i mean, even it will continue on all that. all that i, thanks. ashley were holland, just as there is still an awful lot of potential even with cold cases, gantski equipped within c. hi polen. no matter what we call dying. whether you have somehow retrieved a pollen grain or whether you have a piece of clothing or a strand of hair from the corpse with my holland doesn't decay from delay. she. dep pointing the head. so as long as it doesn't go mousy with the pole and not be wonderfully present when the boy heightens, say, it means we can always isolate pullin from any material material, whether it's 50 years old. chris, for a 100 years old, wanted yadda. and when appropriate, going use it to girl conclusion and say even reduction city ah, current research developments make it look as though no crime can remain unsolved in the future. the search for evidence is too sophisticated to advanced and high

tech. and so 2 of the methods research is used to analyze the traces. but with all these advancements, one thing shouldn't be overlooked. most of these high tech would be redundant without the materials provided by nature. ah really ah a vibrant habitat and and glistening place of long the mediterranean sea, its waters connect people in many cultures. all inclusive holidays
