Our fingerprints are what make us unique -- but they're also home to a world of information hidden in molecules that reveal our actions, lifestyles and routines. In this riveting talk, chemist Simona Francese shows how she studies these microscopic traces using mass spectrometry, a technology that analyzes fingerprints in previously impossible detail, and demonstrates how this cutting-edge forensic science can help police catch criminals. (Note: This talk contains descriptions of sexual violence.)

The same tools that identify those who harm can also be used to frame the innocent. When crime is "cleaned up" how then would society define a terrorist?

She did a chronological mistake in her talk: The overlapping fingerprints can only be visible as single fingerprings (by the software of the computer) BECAUSE those specific molecules found by MS identify the areas of each fingerprint! Only then the computer can compute both images of the fps. She first put the overlapping fp apart and then told us that those substances are only on the killers fp.... thats chronologically wrong!

because no fingerprint is more or less effective than another fingerprint. so yeah, all these different variations survived our evolution. in other words: no matter how your fingerprints form those tiny patterns and loops and spirals, it is as good as mine, provides as much grip as mine. neither yours nor mine has any reason to disappear from the gene pool. fur colour can be a totally different story. the typical lion colour has evolved for tall grass ambushes. any variation (darker or lighter) and the predator is far less effective so all the other colours vanished from the gene pool (with the extremely rare exceptions of white lions who have serious difficulties in hunting ans usually don't survive as long as "normal" lions). Wolves on the other hand are long distance runners. In their case, even black is OK. A black specimen is not more or less effective because their hunt depends on their stamina, not on their stealth. thus many colours survived the process of evolution. Like fingerprints.

I really like this presentation!!! It is kind a scary story, but it is worth it. I think it is a new way to solve crimes. Crimes will decrease as they soledBy using right technology as she said. But everywhere we have two side of the coin. And of course fingerprints can be used as setup. Everyone should be carefully. And follow the recommendation,like “don’t touch anything in someone’s house”. I think it will help you to stay safe. Love yourself and your loved one!

great but that dress is too much a fingerprint in itself - the obvious distraction and to what and statement all in one

I wonder if the pattern of fingerprints also can tell us something about the person.. maybe some patterns are more common among woman or maybe some patterns are linked to the skin color or hair / eyes etc.

Christopher Smith
Of course, that still isn't conclusive evidence that Thomson is the killer or even the rapist. It only proves that he handled the tape at some point. Sad for a hypothetical man to be convicted of rape and murder just because he stocks tape at a hardware store (for instance). That being said, mass spectrometry for fingerprint analysis is still cool.

They can also easily put something with a fingerprint on it into a crime scene. Like they do with DNA. As long as humans are involved it will never ever be airtight and there will always be innocent people who end up in jail to cover for the real criminal. It happens.

Fingerprint forensics is a complete joke and just a way to convince ignorant people to admit guilt... This is the 2.0 version of that. Dont believe people who tell you something and then benefit from you believing a lie...

I am not the criminal but I know one simple thing that do not ever leave anything behind when you commit a crime and concealing begins with hairs and fingerprints and from their list grows like CCTV capture from nearby or anywhere , cell phone location, car no. etc. ! If one is really desperate to get rid of somebody than these below steps one may wanna follow :- 1. Apply cream on your whole body and hair gel with minimum odor ! 2.Apply silver paint cream on your face ! 3. Leave cell phone or any other communication device but can take wireless if one is with accomplice ! 4. Take electric bike if one can otherwise prepare to do jogging through lot of shortcuts and may be for a marathon ! 5. Always take account of the security in the area of the crime ! 6. Disconnect relations or continue to maintain the close relations which depends on the state of mind of the criminal or the situation ! 7.Always wear black clothes and small cloth to cover properly the face if needed on the CRIME NIGHT ! 8. Chose only three occasions : Festival, carnival night or silent dark night or super stormy and rainy night ! 9. Always keep your watch and it will be best if watch is equipped with maps, compass ,timer, led light and other apps as well etc but should not able to receive or send any pings ! 10. Change most of your daily routine , outfits , habits of communication well before in advance or just make it confusing or unpredictable ! REMEMBER ...... planning, practice , observation, patience with commitment and discipline trumps everything !!

Examples of this type of technology are always some murder or rape, but the technology gets used to control us more than help us. To stop a lot of crimes, address the cause of crimes, poverty, greed and lack of empathy.

Dustin Rodriguez
This is very interesting, but I am a bit hesitant. The law enforcement community especially is very willing to buy into junk science. Presenting this kind of evidence at trial and defending it would also be very difficult. If there are methodological problems with these techniques, police will ignore them and it will be impossible for defense attorneys to raise the issues in court. We see this with DNA evidence. Despite studies showing that DNA tests are incorrect (contaminated or for other reasons) about 1 in 100 times, defense attorneys are not permitted to mention this unreliability and only claims like "there is only a 1 in 10 billion chance the subject is excluded" are presented. Attempts to question the reliability of the evidence get painted as the defense attempting to bamboozle the jury with technobabble. Before new forensic techniques are actually used to prosecute people, they need to be rigorously tested in the scientific realm. Every person wrongly jailed based on faulty forensics guarantees the freedom of a dangerous criminal.
Alan Hirschenhofer II
That's a fair assessment, as a former Detective I hear what you're saying, yet I have to point out that finger prints were argued at first also. As for the DNA screwups, both the prosecution and defence can challenge findings through there own perspective labs, and that is or can be quite the mission to locate one with a 100% accuracy. For now, it's what we have. I've seen enough improvements these last 30 year's to know that a lot of wrongfully convicted men and women are now free because of DNA test.
