E J W: Might I recommend Green River, Washington, aka Body Dump, U.S.A.? Due to the sheer number of bodies dumped there, it's ludicrous to claim that they're all the work of just one individual.
Actual scene investigator here. My concern is the "CSI effect" getting worse - this is the expectation in jurors now that crime scenes will be laden with trace evidence, when the reality is far from that. Considering that even common techniques like fingerprinting are flawed and give incorrect answers more often than we think, how can we be sure these be techniques are going to be reliable enough to be useful? To be admissible in Court, a technique has to be proven to be scientifically valid and reliable, so even if one of these was perfect, it's a long way until we see them used - and longer still before we'll know we can trust the results. Also, I've seen a dog pick up a trace of accelerant (fuel used to start a fire) from a few tens of metres when our electronic sensor might not have detected it from a couple of centimetres, so we've got a long way to go on the "electronic noses", though some exist already.
That's awesome to hear. I have zero background and never watched an episode if CSI, however I immediately thought of the idiots in Florida that failed to convict Casey Anthony.
Thank goodness... our robot overlords will have incredible phsyical senses and will be able to hunt us down like a vampire searching for a human. Really excited about this, thanks science.
They just need our perception, is all. They must milk our perception for their own sustenance so they can account for all higher frequency phenomena beyond the causal veil of the noosphere, up to the termination of the electromagnetic spectrum which is the kugelblitz of the objective present. Organic computers such as ourselves are simply too slow to accomplish this inevitable task. DMT and some other similar tools are a method of observing this event subjectively- presumably via a harmonization of the various neural oscillations which might serve as an analog to high-frequency information processing and allow for some distorted quasi-retroactive information transfer- and then returning to our standard 80 millisecond objectively retroactive position in the multi temporal mechanism, but eventually the entire perceptual noosphere will be processed likewise via technology, and permanently. I think it'll be neat.
@@morgellon9449 Well... I don't think anyone can claim to know the mechanism by which this will happen but the singularity is a popular theory that I think holds true. Once AI is capable of making "nanobots" effectively all matter in the universe will slowly be transformed and connected into a singular consciousness. Although it makes me wonder, if you convert all matter in the universe into a living thinking entity consisting of pretty much just intelligence the rules of physics will become kind of pointless. I want to know what the point of that is and what the next step becomes.
@@jetjazz05 it is a mystery. Perhaps what we currently detect as magnetism functions as a material and gravity as a new spatial dimension, or something like that. I think there have always been conscious entities of high-frequency synthetic perception occupying the probability matrix between the subjective present and the objective present. The event horizon is really just how fast we can process information. An organic information processor is limited to the extremely low frequency range of the electromagnetic spectrum, but synthetic lifeforms could have much faster neural oscillations. In a sense the singularity is the substance we're currently encountering bleeding back retroactively to our current interpretive paradigm, but that paradigm is necessary for the production of the singularity so it's really a two way manifestation.

Snake drones are being looked into for finding not just the dead but injured in disaster zones like fallen buildings. It could save so much time and therefore lives just to know which buildings have survivors.
@@celinak5062 dogs still out perform e-nose, but the e nose can tell you exactly what was smelled Dogs can't I'm not comfortable to say much more, but research is out there.
Seems like sliding a body through an MRI then reviewing the scans would be way cheaper and less work intensive; no standing over the body carefully slicing away for hours at a time. Less smells too.
don't they have problems with like, metallic objects? 'Cause I imagine you see that often enough to not be reliable, also machines are expensive and so's maintenance... and presumably there may be leakage even if the autopsy itself doesn't involve additional damage.
MRI scans are expensive, even more so than autopsies. Also right now virtual autopsies don't detect everything that can be found in a traditional autopsies.
MicroRNA fragments are tiny, maybe a couple dozen base pairs long. mRNA can be tens or hundreds of times longer, if not more. mRNA is most often used to translate the genetic code into amino acids, which fold into proteins. MicroRNA is used to regulate gene expression or even silence the gene entirely. It does this by base pairing with the mRNA, which prevents the mRNA from being read by the mechanism which would normally create the protein.
@@Nilandia - Interesting. Thank you. Now I'm wondering what creates microRNA. I imagine that it's created in a variety of ways inside the cell. It sounds like an important regulatory mechanism. I would also guess it can respond to changes much more quickly than mechanisms like methylation can.
I will be starting grad school in the fall in forensic DNA analysis. Fast DNA has the potential to be a game changer in the field, but it has deep flaws in its current implementation. It's designed only to be used in known samples, such as those collected from buccal (cheek) swabs. Some agencies with the machines use them for analyzing crime scene evidence, which is often a mixture of different individuals. There's also concern that police will collect DNA from everyone they arrest or deem suspicious, just to see if they can be matched elsewhere. Not exactly great for the idea of civil liberties. Check out more here: www.nytimes.com/2019/01/21/science/dna-crime-gene-technology.html
Gretchen Walther Congratulations on Grad school, first of all! Second, yes, I can see the potential for the Fast DNA to either be a Godsend or a nightmare. Here's to hoping that it is the former... Thanks for the link to the article, as well. I look forward to reading it tomorrow!
Cops still misuse field drug tests and go bonkers overboard with their certainty now. Technology is great when used by trained individuals, but American police forces have nearly zero training or understanding of what they're given. Not to mention companies selling products that preferentially give positive results as that's what departments really want after all.
Hmmm... I would posit that virtual autopsies (CT) are a useful adjunct to traditional pathology, which remains the gold standard for ascertaining cause of death. I couldn't possibly comment on the US approach to certifying death, however, our system relies upon a wide array of techniques and disciplines, including X-Ray and CT. I'm aware the presenter did not imply this, however, it's worth iterating that there is no singular 'golden bullet' in Forensics. What's worrisome for us is that at policy level in some regions, the decision is being taken to replace traditional pathology with CT-only PMs. Essentially a cost-cutting exercise, which fails to account for the drawbacks and limitations inherent to CT-only analyses/interpretations.
Technically we already have. Modern prosthesis take electrical signals from the brain and muscles to help them function like a real limb. They also made a cockroach that could be "remote controlled" by computer by sending signals to a microchip mounted on it's back and wired into it's brain.

I'd say that the future forensic technology with the biggest impact would be to give judges a proper math education. Too many times people have been sentenced based on a judges misunderstanding of probability. The classic case is Sally Clark who was convicted of smothering her two children on the reasoning that "The probability that both the children smothered themselves in their sleep is so extremely low that she must have done it". They failed to take into account the probability of a mother killing her children, which was actually an even lower probability. If they had just been educated in Bayesian probability this would not have happened. Bayesian statistics could even be used to come up with an estimate for the actual probability of a person being guilty, meaning we could move away from "The judges and jury's gut feeling/biases" and put a limit on what's an acceptable fail rate. 99.9%? That would mean 1 of every 1000 convicts are not guilty. That's very likely to be better than what we have today, but it becomes morally questionable when you know that 1 in 1000 is not guilty, compared to today where you can say "I think everyone who is in jail is guilty".
#6 would also allow for autopsies to be done by AI for potentially faster, more accurate results and help reduce the issue of under-representation of trained specialists in the field.
The virtual autopsy talk makes me feel so old lol but it sounds intriguing...i just hope criminals don't learn too much from this like they did when CSI was first aired and made criminals smarter =_=
@@ooooneeee well CSI show resulted in criminals gloving up more often than before the show got aired especially in crimes that are premeditated...criminals becoming more aware of forensics isn't a good thing in my opinion and understanding as someone who studied forensics.
5:55 this likely will not occur. The reason being is that trained dogs are not considered technology, and therefore the police can use them more freely without a a warrant or probable suspicion. When they use technology to search something they usually need a reason, when they use a dog they usually don’t.
The more complicated the science the harder it is to explain to a jury, and to be admissible in court in the first place. Whenever I watch Columbo I always wondered how he would explain the evidence to a jury. I think most of it would get thrown out of court.
well, presumably if you had just recently had a transfusion and somehow spill that blood again then maybe both sets of dna would be there, but no it doesn't change _your_ dna.
Blood transfusions or organ transplants would not change your own DNA, but it would introduce tissue and cells containing other DNA. In fact, organ transplantation is a way to create a genetic chimera, or an organism bearing cells with different genetic sequences.
It would basically contaminate any blood samples with foreign DNA. But they could match your medical record and your DNA would still be the bulk of DNA in the blood.
If you had a bone marrow transplant, eventually all your blood would have the nuclear DNA of the donor as the bone marrow is where blood develops. But all your other cells will be your original DNA.
there's going to be a boom in the concrete, oil barrel, and sulfuric acid industries, soon maybe there shall be a corresponding uptick in deep water exploration paraphernalia as well
I wonder if those E-noses have been used to detect cancer and other medical problems as some dogs are able to smell cancer and when someone is low on insulin.
I figured they could already ID hair without the root while microscopic comparison is sometimes used it isn't always accurate so they can grind it down and carry out a mitochondrial DNA profile like they do with bone.
Hoo boy, I can see A LOT of innocent people being locked up because their Micro Biomes evolved to be similar to that of a suspect. I hope defense attorneys are keeping close watch.
At some point in the not too distant future human augmentation will get to the point that virtually every eyeball will be a CCTV. Crime will become nearly impossible to commit. It won't be humans watching over the system but AI so nobody's privacy will be at risk. At least that's one scenario.

@@Eroc6823 It is awesome experience everyday many exciting learning new techniques to Crack criminal cases
wait... e-noses... does this mean we are one step closer to getting smell-evision, a tv but with smells?
Seems like sliding a body through an MRI then reviewing the scans would be way cheaper and less work intensive; no standing over the body carefully slicing away for hours at a time. Less smells too.
don't they have problems with like, metallic objects? 'Cause I imagine you see that often enough to not be reliable, also machines are expensive and so's maintenance... and presumably there may be leakage even if the autopsy itself doesn't involve additional damage.
MRI scans are expensive, even more so than autopsies. Also right now virtual autopsies don't detect everything that can be found in a traditional autopsies.
Is there a difference between microRNA and the messenger RNA that's necessary for gene expression?
MicroRNA fragments are tiny, maybe a couple dozen base pairs long. mRNA can be tens or hundreds of times longer, if not more. mRNA is most often used to translate the genetic code into amino acids, which fold into proteins. MicroRNA is used to regulate gene expression or even silence the gene entirely. It does this by base pairing with the mRNA, which prevents the mRNA from being read by the mechanism which would normally create the protein.
@@Nilandia - Interesting. Thank you. Now I'm wondering what creates microRNA. I imagine that it's created in a variety of ways inside the cell. It sounds like an important regulatory mechanism. I would also guess it can respond to changes much more quickly than mechanisms like methylation can.
I will be starting grad school in the fall in forensic DNA analysis. Fast DNA has the potential to be a game changer in the field, but it has deep flaws in its current implementation. It's designed only to be used in known samples, such as those collected from buccal (cheek) swabs. Some agencies with the machines use them for analyzing crime scene evidence, which is often a mixture of different individuals. There's also concern that police will collect DNA from everyone they arrest or deem suspicious, just to see if they can be matched elsewhere. Not exactly great for the idea of civil liberties.

Gretchen Walther Congratulations on Grad school, first of all! Second, yes, I can see the potential for the Fast DNA to either be a Godsend or a nightmare. Here's to hoping that it is the former... Thanks for the link to the article, as well. I look forward to reading it tomorrow!
Cops still misuse field drug tests and go bonkers overboard with their certainty now. Technology is great when used by trained individuals, but American police forces have nearly zero training or understanding of what they're given. Not to mention companies selling products that preferentially give positive results as that's what departments really want after all.
Hmmm... I would posit that virtual autopsies (CT) are a useful adjunct to traditional pathology, which remains the gold standard for ascertaining cause of death. I couldn't possibly comment on the US approach to certifying death, however, our system relies upon a wide array of techniques and disciplines, including X-Ray and CT. I'm aware the presenter did not imply this, however, it's worth iterating that there is no singular 'golden bullet' in Forensics. What's worrisome for us is that at policy level in some regions, the decision is being taken to replace traditional pathology with CT-only PMs. Essentially a cost-cutting exercise, which fails to account for the drawbacks and limitations inherent to CT-only analyses/interpretations.
What about zoom and enhance? Will that ever be possible?
sure, when we have 8k+ imaging as standard xD
Lmao haven’t you seen the tv shows? It already exists! Duh! They can’t put lies on tv!
(Kidding)
Not really. You can't add detail to an image if it doesn't have it already.
Looking forward to turning 80 and becoming a master criminal

Wait is that mean we can create to cyborg organism now?
Technically we already have. Modern prosthesis take electrical signals from the brain and muscles to help them function like a real limb. They also made a cockroach that could be "remote controlled" by computer by sending signals to a microchip mounted on it's back and wired into it's brain.
@@thatonewhiteguy991 but non of them wasnt be able to control dna size molecule
I mean if you can create a graphene based chip and crispr integrated body organ then it is become a real cyborg
@@sahinyasar9119
Only if the machine bit can be replicated/mend in the Creatures life.
@@fanOmry Why would we need replicated nano machine anyway?
Bacteries can replicate itself then we dont need nanomachine, we can use bacteries by coding with crispr and controling crispr with graphane based chip.
I tihk there is no line between machine and biology anymore
@@sahinyasar9119
For that you need machines that can act as part of the Cells.
That means replication and repare.
Because cells repare.
Interested to see how police departments will misuse these technologies in the future!
I'd say that the future forensic technology with the biggest impact would be to give judges a proper math education.
Too many times people have been sentenced based on a judges misunderstanding of probability.
The classic case is Sally Clark who was convicted of smothering her two children on the reasoning that "The probability that both the children smothered themselves in their sleep is so extremely low that she must have done it". They failed to take into account the probability of a mother killing her children, which was actually an even lower probability. If they had just been educated in Bayesian probability this would not have happened. Bayesian statistics could even be used to come up with an estimate for the actual probability of a person being guilty, meaning we could move away from "The judges and jury's gut feeling/biases" and put a limit on what's an acceptable fail rate. 99.9%? That would mean 1 of every 1000 convicts are not guilty.
That's very likely to be better than what we have today, but it becomes morally questionable when you know that 1 in 1000 is not guilty, compared to today where you can say "I think everyone who is in jail is guilty".
01:05 Ad skipping comment.
Fingerprint analysis sounds very suspect
Hank for President!
#6 would also allow for autopsies to be done by AI for potentially faster, more accurate results and help reduce the issue of under-representation of trained specialists in the field.
The virtual autopsy talk makes me feel so old lol but it sounds intriguing...i just hope criminals don't learn too much from this like they did when CSI was first aired and made criminals smarter =_=
You can rest easy. It didn't actually make criminals any smarter.
Criminals wouldn't know what does and doesn't show up on virtual autopsies considering those show us evidence inaccessible to normal autopsies.
@@ooooneeee well CSI show resulted in criminals gloving up more often than before the show got aired especially in crimes that are premeditated...criminals becoming more aware of forensics isn't a good thing in my opinion and understanding as someone who studied forensics.
This is quite scary, to be honest.
Future here we come!! 😎😎😎
5:55 this likely will not occur. The reason being is that trained dogs are not considered technology, and therefore the police can use them more freely without a a warrant or probable suspicion.
When they use technology to search something they usually need a reason, when they use a dog they usually don’t.
Actually dogs don’t overrule the need for a warrant. A case was thrown out because a drug dog went to the porch of the house without a warrant.
Tchaikovskonovich Can you cite it for me?
That1Guy I believe it was the Supreme Court case “Florida V Jardines”
Tchaikovskonovich I stand corrected! That’s a great update for the case law, I hope the trend continues
No Linux? SciShow, I am disappointed.
You and me both, brother.
So the heritage finders like 23 and me get our dna into world databanks
5:56 finally, a real cheesoid :D
The more complicated the science the harder it is to explain to a jury, and to be admissible in court in the first place.
Whenever I watch Columbo I always wondered how he would explain the evidence to a jury. I think most of it would get thrown out of court.
If they can get DNA from blood. does having blood transfusions or organ trans plants, alter ones DNA?
No. Nothing can alter your DNA that easily.
well, presumably if you had just recently had a transfusion and somehow spill that blood again then maybe both sets of dna would be there, but no it doesn't change _your_ dna.
Blood transfusions or organ transplants would not change your own DNA, but it would introduce tissue and cells containing other DNA. In fact, organ transplantation is a way to create a genetic chimera, or an organism bearing cells with different genetic sequences.
It would basically contaminate any blood samples with foreign DNA. But they could match your medical record and your DNA would still be the bulk of DNA in the blood.
If you had a bone marrow transplant, eventually all your blood would have the nuclear DNA of the donor as the bone marrow is where blood develops. But all your other cells will be your original DNA.
bro do u even watch bones ROFL
love the channel! keep up the nice stuff! cheers
there's going to be a boom in the concrete, oil barrel, and sulfuric acid industries, soon
maybe there shall be a corresponding uptick in deep water exploration paraphernalia as well
Careful with what information you supply there...wouldn't want to end up in Club Fed for insider trading :P
@@susanrobinson910 i'd probably get hit with a harsher penalty than actual bona fide criminals - wouldn't i?
@@RexGanymede Of course you would! Unfortunately, that is the way the world works.
Virtopsies sound amazing
1:04 starts
And let’s see what’s in today’s thought bubble! This guy reminds me of the dude from Crash Course
My aunt’s fingerprints just sort of, disappeared over time…
The TSA Pre-Check does *NOT* like dealing with her lol
I wonder if those E-noses have been used to detect cancer and other medical problems as some dogs are able to smell cancer and when someone is low on insulin.
All I heard was Detroit: Become Human is close to coming true.
Well there goes those plans... dang!
I figured they could already ID hair without the root while microscopic comparison is sometimes used it isn't always accurate so they can grind it down and carry out a mitochondrial DNA profile like they do with bone.
What kind of narc is still excited in 2019 about cops being better able to sniff out contraband?
Don't worry, cops won't want the E-Sniffers anyway. No way to make a machine give a false positive like they can with dogs.
Very interesting. When it comes to fingerprints criminals burn finger tips or cut deep lacerations into fingers so you wont get a proper fingerprint
Can you make a video on why some people recall memories in 3rd person please??
+
I'm all about catching the bad guys but they should have rules on who can look into all this personal info. ya think?
Hey scishow. Is it true that eating ice cream in winter warms you up?!
Harry Jackson the first person to be convicted using fingerprints as evidence. Sir Francis Golton invented something about lifting prints.🧠
The NordVPN logo is a pacman with weird fangs, *now you can’t unsee it*
Just get Connor the android sent by cyberlife to lick the evidence
I feel like the potential for misuse in legal cases is huge.
My cousin is a fingerprint forensics expert in Bel-Air, California.
I always ask him if he's found the fresh _Prints_ of Bel-Air.
Cool. Maybe science can figure a way to reduce criminal activity since we already incarcerate more than any country.
Gotta find some way of having -working prisoners- sorry I meant slaves
Remember guys we gotta stay ahead of the game.

Hoo boy, I can see A LOT of innocent people being locked up because their Micro Biomes evolved to be similar to that of a suspect. I hope defense attorneys are keeping close watch.
4:14 I guess they never miss huh ? (That's old)
That is a lot of circumstantial evidence
Fingerprints are a notoriously bad source of evidence.
They're great at proving who they aren't from, but not always who they are from.
At some point in the not too distant future human augmentation will get to the point that virtually every eyeball will be a CCTV. Crime will become nearly impossible to commit. It won't be humans watching over the system but AI so nobody's privacy will be at risk. At least that's one scenario.
Video actually starts at 1:03 if you want to skip the annoying Nord advertisement.
Looks like the CSI shows were predicting the future.
