in many ways it's a development of Sherlock Holmes and his magnifying glass, isn't it? Dr Lafford: Yes, you could put it that way, although we've come a long way since then of course, but Holmes was very much a detective of the modern age - of course he was an intelligent man and his medical knowledge often seemed better than that of his companion Dr Watson, and certainly his observations were always very detailed but what sets him apart is that (1) Holmes provides us with a good model - a very good model in fact - of the kind of approach psychological approach - that a forensic scientist should have, and that is that the forensic scientist is absolutely impartial Interviewer: So, you're not strictly speaking part of the police force ? Dr Lafford: No, we are quite separate Interviewer: Could you tell us a little about your work and what it is you do? Dr Lafford: (2) Well, the basic principle behind forensic science is that every contact leaves a trace Wherever we go, whatever we touch, material is transferred both ways The shoe that leaves a mark on the ground also picks up traces of dirt, and the hand that makes a fingerprint also carries away particles from the object that was handled and things like hair or carpet fibres are easily passed from one person to another Interviewer I see, so it's not just that the suspect leaves clues at the scene of the crime, the scene of the crime leaves clues on the suspect Dr Lafford: Absolutely, and that is normally the most compelling evidence - not just when you have a fingerprint, for example, but also where you've found traces of, say, the carpet at the scene of a crime on the suspect's clothing, and that, of course, can be very hard to explain away Interviewer: Is your work fairly straightforward - a question of seeing whether various samples match up? Dr Lafford: No, no, no, not at all (3) forensic science is often a very painstaking task - and very timeconsuming - much more so than previously, in fact, because the range of tests has mushroomed for example, we might be given some pieces of a headlight swept up after a hitand-run accident and asked to identify the car, so we would fit the thousands of pieces together like a vast jigsaw, and might be able to identify the number embossed on the back of the glass that would help us identify the model of the car, the make, the age, and so on, making it easier to search for the suspect and then, once the car was located, we could tell whether the lights had been on at the time of the accident by examining the light bulb, because there would be minute pieces of molten glass on the metal filament in the bulb Interviewer: So you need some fairly sophisticated equipment as well as patience Dr Lafford: Indeed! Now, the electron microscope is invaluable in our line of work - and it basically does two things - it gives us a fantastically detailed image, so, for example, you can tell whether a piece of hair has been broken, or cut with a pair of scissors or a knife (4) And it can also give you the chemical composition of a sample, so that you can take, perhaps, a tiny flake of paint on a suspect's clothing and match it with paint at the scene of the crime Interviewer: Are you at the stage then where you could say that the evidence that you provide is foolproof? Dr Lafford: No, not foolproof There is always room for human error and there's nothing that can be done about that forensics is not an absolute science - I mean, let me give you an example Now, Sherlock Holmes might have found a strand of hair at the scene of a crime, perhaps black and two inches long, that would have helped him identify the murderer on the basis that the hair matched the murderer's Now, we also examine hair but in the example I gave you, perhaps one person in twenty has black hair two inches long, so we need to improve on this analysis (5)to narrow down the number of suspects So, we would analyze the strand of hair using the electron microscope, as I was saying earlier look at its chemical composition, whether it came from a man or a woman, see how it was cut, whether it showed any traces of particular chemicals and so on, and in that way, (5) instead of saying that one person in twenty had hair like that, it might be one person in 500,000 or a million That would just about as far as we could go Now there's no such thing a certainty just a balance of probability, even with the most advanced techniques of genetic fingerprinting The evidence we provide is there to be interpreted, and that's very important Interviewer Well, Dr Lafford, thank you very much We'll take a break now, but stay with us and we'll be back Part 2: Good morning and welcome to yet another lecture in Environmental Science I don’t think I am telling you a secret when I mention that water is a big worry here in Australia The stuff is scarce Perhaps that’s why we drink so much beer, eh? Seriously, though, a safe and reliable source of water is one of the great concerns of people everywhere Moreover, as the world population grows, the pressure on existing water supplies grows greater and greater Think about it Our economic system demands that there be more and more consumers The growing number of people has been tied to climate change, including droughts So more people means less water But our economic system demands a high birth rate Forget about oil Soon enough you will see wars for water Mark my words But today, I’m going to confine my remarks to Australia As noted already, here down under, the water supply is extremely scarce The only drier continent is Antarctica - and remember, no one really lives there anyway Moreover, in recent years, the wind patterns have changed Rain that used to fall on the country now falls out to sea hundreds of miles to the south Now, when I speak of people needing water, most of you probably think of drinking Certainly everyone needs water for drinking But surprising as it may sound, drinking is not anywhere near being the main use for water Most water is actually used for washing When you take a shower, you probably use well over a hundred litres of water Every time you flush your toilet, that’s about eight litres But most people drink no more than two litres or so per day So, where to get water? It could be obtained from rainwater, but often rainfall consists of other harmful pollutants that evaporated with the water In fact, acid rain, an intense example of this, causes harmful effects on the wildlife of the habitat on which it falls Water from underground could also be used, though it is more difficult to contain and often must go through an extensive cleansing process The purest water is found in rivers, creeks, lakes, and dams And, sad to say, Australia has precious few of these Really, how many of your home towns have rivers? Year-round rivers, I mean The soil tends to be sandy, so water soaks into the ground Many places are rocky too, so 87% of the rainfall is lost to evaporation That’s almost twice the evaporation rate in my native Canada! Speaking of rain, we already heard how rainfall is diminishing here in Oceania The quantity itself isn’t the only problem, either Going back to the problems with obtaining rainwater, a further problem is that rain is a useful source of water only if air pollution is fairly mild Again, you’re in a situation where you can’t win You need water where most people live People tend to build cities where rainfall is adequate But then modern cities tend to feature polluted air which renders the rain far less easily usable OK, let's take a look at the table here, you’ll see it showing the relative pollution of rainfall in the world’s cities The more people, the dirtier the rain This is becoming a huge concern for people in the West, who want their water to be pure and safe Though reliable drinking water is important everywhere, the concern in the West is reflected in all the government regulations and political campaigns aimed at solving this problem In contrast, there are not as many demands made on the governments in Asian and African cultures to improve the water, as their focus is on other issues Now, whatever the source of water, we can never afford to forget that all water is highly vulnerable to contamination Whether we’re getting it from the ground, from bodies of water, or rainfall, it is susceptible to a variety of toxins In fact, that’s why we clean it before using it: water carries with it filth and dirt This problem shows up in a number of different ways As humans and all other animals need water to survive, it's no surprise to us that one of the most important domestic uses of water is for drinking Yet if you have old-fashioned lead pipes, you may slowly be poisoning yourself by drinking that nice clear water The industrial pollution, farm chemicals, and leaky landfills are well-known sources of contaminants as well So what is being done to ensure we Australians a safe and steady supply of drinking water? There are a lot of initiatives that make admirable efforts to remedy this issue We’ll be talking about this when we meet again on Thursday But, as a preview, I can tell you that so far the amount of real solutions that have been produced is not nearly adequate Traditionally, we’ve been very free in this country That means that every person and every province tend to go its own way So the mechanisms for water management are, in a word, insufficient To begin seeing how this is so, I want you to read something before our next class Though a lot of previous data on water usage and water management are inconclusive and have thus caused quite a concern, we can learn a lot from the content of reports written on the subject The basis for the government’s water policy is the 1989 White Paper reporting on “Water Use: Present and Future” If you compare the numbers offered in the paper with those in the text, you’ll find that the report is rather untrustworthy Truth being told, I’m being too kind when I say that! Part Presenter: OK, today I have with me Kathy Ford, winner of more than 500,000 worth of prizes in all sorts of consumer competitions and dubbed ‘The Queen of Competitions’ by the British press She’s now editor of Competitor’s World magazine and as an expert on competitions has appeared regularly on TV Kathy, let’s go straight to our first caller, and that’s Diana Diana, what’s your query? Diana: Yes, hello Kathy Well, in order to send in two entries to a competition where only one entry per person was allowed, I asked my best friend if I could submit an entry in her name She agreed, and the understanding was that, if ‘her’ entry won, I would receive the prize, but I would buy her a small gift for allowing me to use her name Well, the inevitable has happened - I’ve won a muchneeded new washing machine, but in my friend’s name, and she has now refused point blank to hand the machine over If I went to a lawyer, would I have any hope of getting my prize from her? Kathy: Not even the faintest chance I’m afraid that your efforts to evade the rules have not only cost you the prize, but also your best friend as well, and legally you just don’t have a leg to stand on Even if you’d drawn up some sort of legal agreement with your erstwhile friend, I think you’d find that the law would still take a very dim view of your case, since it was obviously done with premeditated fraudulent intent It’s not worth trying to evade the rules as you’ve just found out the hard way Presenter: Next, it’s Ron Ron, go ahead, you’re through to Kathy Ron: Someone told me that some firms that run competitions keep a blacklist of frequent prizewinners, and that I should use a lot of different aliases in order to avoid being put on such a list Is this true? Kathy: No! Competitors can sometimes get a little paranoid, and if they start going through a winless spell (and we all get them, from time to time!) they start to imagine that they’ve been blacklisted No reputable firm would even contemplate such a measure, and the only time there’s even a faint risk of this sort of thing happening is with ‘in store’ competitions, where an individual store manager might just conceivably think ‘Oh no, not him again’ and deliberately disregard your entry For mainstream competitions, however, such worries are groundless, and the use of aliases is not only unnecessary but can even prove to be pretty stupid Think about it for a moment - what would happen if you won a holiday under a phoney name? Or were asked to prove your identity to collect a prize at a presentation ceremony? My advice is to stick with your own name and if prizes stop arriving, take a long, close look at the quality of your entries rather than trying to blame it on blacklists Presenter: OK, next it’s Stan Stan, what can Kathy help you with? Stan: Well, Kathy, I recently entered a competition which asked you to estimate the distance between a store in Newcastle and its London head office, using the shortest route In order to make my entry as accurate as possible, I used a Routemaster computer program to determine the shortest possible way and calculate the distance, quite literally, from door to door Imagine my astonishment, therefore, when I sent for the results and found that the answer they had given as being ‘correct’ was fully 73 miles longer than mine I know my answer was correct, so I have grounds to make a formal objection? Kathy: I’m sorry, but no, you haven’t As far as the promoter is concerned, the key word in the instructions, here, is ‘estimate’ - they expect you to guess, not measure the distance accurately, and it’s likely that their own answer will also be based purely on an estimate As a result, judges will always be right, even when they are wrong as in a case like this, and in entering the competition at all, you have agreed to abide by the rule that states ‘the judges’ decision is final’ Distance estimation competitions have always given rise to this sort of controversy, and although court cases have been brought, the entrant very seldom succeeds in having the decision changed You have only to check the distance charts in road atlases to see how this type of problem occurs No two ever agree, yet as far as I know, towns simply don’t move around very much! Presenter: OK, and now on to our next caller, who is Part https://www.youtube.com/watch?v=dhZlSxN162Y At some very important level this is good specifically this is a good girl a good girl named Cobra because because why not a dog looking for Covid is it even possible evidently it is and now you can find them at Miami international airport four dogs trained to detect Covid 19 as part of a pilot program this is cobra one of the dogs trained to detect the virus watch how she sits after she smells the inside of a mask that has deactivated virus in it then watch how she just keeps walking when she smells the mask of someone who's not infected the dogs are 97 percent accurate i mean it's the same as a pcr test so i mean it's a great it's a great thing miami international airport is the first in the nation to have the dogs i think in this particular airport now we're doing it with the employees but people uh will see the dogs and know that that's another weapon that we're using to fight this pandemic that's coverage from wtvj um in in miami uh one of the dogs is named cobra she's a seven-year-old belgian melanois the other dog is also a seven-year-old girl she is a dutch shepherd her name is one betta as in I can that one better you want to know how it breaks down dog by dog of course you uh one betta the the uh the dutch shepherd her accuracy rate is 98.1 percent and Cobra the belgian melanois here uh she is 99.4 percent accurate as a covid test the dog is and that is a published peer-reviewed double-blind study I mean we're familiar with dogs sniffing for drugs dog sniffing for explosives in a custom setting some dogs are trained to sniff out large amounts of paper currency that might be hidden in someone's luggage dogs can amazing stuff these particular dogs before becoming kovid experts they were agriculture detective dogs their specialty in customs was i kid you not sniffing out laurel wilt which is apparently terrible for avocado Trees so it's their job to like sniff agricultural products and find out if anybody was accidentally bringing laurel wilt into the country but now they're off laurel wilt the laurel wilt beat leaving that to other pups and these dogs are retrained to fin kovid instead here's the provost at florida international university's a chemistry professor this is where they trained the dogs explaining how it works when you get Covid 19 you produce volatile organic compounds it's called on the chemist so vocs and those vocs are what the dog detects researchers at fiu trained the dogs to detect cobit 19 by using face masks from cobot patients we basically use ultraviolet light to kill the virus and the odor is still there so he goes on to explain that these dogs are so good at sniffing out Covid 19 infections sniffing out the volatile organic compounds produced by someone who's infected he goes on to explain that if you wanted to you could actually train these dogs to key on one specific variant of the virus their noses are so sensitive you could train them specifically to only sit down if they sniffed the delta variant of the virus or the move variant of the virus or whatever they can be that sensitive we may have an apocalyptic mess on our hands in every other possible way but as a civilization we have now successfully retrained the avocado tree laurel wilt agricultural pest dog detectives into dogs who instead can tell you if you need to get a rapid covent test before you come into work - The end – ... in in miami uh one of the dogs is named cobra she's a seven-year-old belgian melanois the other dog is also a seven-year-old girl she is a dutch shepherd her name is one betta as in I can that... him apart is that (1) Holmes provides us with a good model - a very good model in fact - of the kind of approach psychological approach - that a forensic scientist should have, and that is that... straightforward - a question of seeing whether various samples match up? Dr Lafford: No, no, no, not at all (3) forensic science is often a very painstaking task - and very timeconsuming - much more
