Dali’s DNA Test Reveals His Brilliance?

Forensic Scientist Uses Dna to Explore Dali’s Bizarre Genius

Samples taken from nasal feeding tubes could also help to authenticate works.

It is like something from a surrealist still life – a hat, glasses, moustache and toilet seat. This is the collection of belongings that forensic scientist Michael Rieders was offered when he put the word out that he was trying to track down Salvador Dali’s DNA.

"I have been fascinated by Dali and his artwork since I was around 11 years old," he said. "I found it hard to believe that a person could come up with such exotic, bizarre art."

By tracking down Dali’s DNA he felt he could get closer to the surrealist artist. But more than that, he hoped that if he could characterise Dali’s DNA fingerprint, he could use it to help authenticate the handful of paintings and artworks that are not signed but are claimed by some to have been painted by the Spanish master.

Dali’s DNA might even hold clues to the man’s creative genius. "He was just a machine of creativity at all levels," said Bruce Hochman, director of the Dali Gallery in San Juan, California. "Not only was he a great painter, he could work in any medium." Dali also designed jewellery, designed sets for Disney, wrote and starred in an opera and was an accomplished draughtsman.

When the "Dali universe", as Dr Rieders calls it, began offering to sell him objects to test for DNA he suspected most respondents were opportunists. But then he was given an unmissable chance of getting close to Dali’s DNA.

Mr Hochman put Dr Rieders in touch with two of Dali’s closest friends, Robert and Nicolas Descharnes. They had kept two nasal tubes nurses had used to feed the painter when he was recovering from a fire in 1984. The blaze, which was started by an electrical fault at his castle in Pubol, France, left Dali with second degree burns on his leg and burns to his throat from breathing in the hot smoke.

"I’m not 100% sure why [they kept them]," said Dr Rieders, a toxicologist and lab director at NMS Labs in Willow Grove, Philadelphia, "but I now had an artefact that I was reasonably sure would contain some of Dali’s DNA."

The Descharnes, renowned authenticators of Dali’s work, had stored the tubes in sealed envelopes signed and dated by Dali’s doctor and nurse.

Jon Benet Ramsey DNA Evidence

Dr Rieders told the annual meeting of the Academy of Forensic Sciences in San Antonio, Texas, that his team took swabs from 19 different places on the outside of the tubes. The profiles – which included DNA markers at 16 different sites on the chromosomes – all pointed in the same direction. "They all ended up coming back to a single male individual. This was a good sign," he said.

The next step is what to do with the DNA. "Let’s be clear about this. I have no intention of creating a cloned army of surrealist artists," said Dr Rieders, who sported a melting clock tie in honour of one of Dali’s most famous images.

One priority is to preserve the DNA for future testing. The team have offered one sample of the DNA to the Dali Foundation in Spain, one to the Dali Museum in St Petersburg, Florida, and one to the Forensic Archaeo-Toxicology Institute, an organisation that retains DNA samples from significant cases. "We want to make sure that if a catastrophe should happen in Willow Grove, Pennsylvania, we won’t lose the chance of having Dali’s DNA," said Dr Rieders. Dali died in 1989 leaving no descendants.

One possibility would be to study Dali’s DNA for clues to his artistic genius. Perhaps he had a mild form of schizophrenia or bipolar disorder which fuelled his creativity.

"Dali collectors will want to use the DNA profile to help establish whether the huge amounts of supposed Dali paraphernalia that exists is real. There are many Dali objects out there, some on eBay, that are claimed to have been in the possession of Dali," said Dr Rieders.

"We now have the art world very interested in using this Dali DNA reference as a way of looking to see if some of the other objects and artwork out there could perhaps be Dali’s."

One piece in particular, a small watercolour called The Snail and the Angel, has a brown stain on it that is supposedly Dali’s semen. The authenticity of that painting is not in doubt, but Dr Rieders thinks it would be a good place to start to try out the DNA fingerprint.

What is a Medical Examiner?

What is a Medical Examiner?

A medical examiner is a medically qualified government officer whose duty is to investigate deaths and injuries that occur under unusual or suspicious circumstances, to perform post-mortem examinations, and in some jurisdictions to initiate inquests per Wikipedia.

 Is a Forensic Career Right for You? 

 A medical examiner (ME) is a doctor of medicine who has gone through med school and is licensed to practice. Most ME’s are trained in pathology, particularly forensic pathology. This means they have specialized training in ballistics, chemistry, biology, entomology, pathology and probably physics to ascertain causes of death.  The ME is expected to apply medical expertise during the evaluation of crime scene, bodies and collected evidence.

 

The ME usually oversees the crime lab and all aspects of death and criminal injury. The primary duty of the forensic pathologist is to perform autopsies, which are needed to determine the cause and manner of death.  This may take the ME down several paths as the crime scene, blood analysis, physical exams and autopsy all will provide evidence.

 

What Does It Take To Be A Medical Examiner?

Luckily, the ME is usually an applied/qualified vs. appointed job so that the politics of running a campaign do not influence results of his/her department.  This is a direct contrast to some towns’ coroner which is an elected official with little to no medical training.  As a public servant, many coroners are more of an administrator and outsource the forensic work to qualified labs.

Forensic Uses of Mitochondrial DNA

Forensic Uses of Mitochondrial DNA

Mitochondrial DNA analysis is a boon in forensic studies, as it is used to solve difficult cases, especially in case of degraded samples that lack nuclear DNA. Here is some information on how mitochondrial DNA is used in forensics.

 Click Here To Find The Best Forensic Science Schools! 

Mitochondria (singular – mitochondrion) are organelles responsible to convert the energy from food into simpler energy forms that can be used by the cells. Hence, mitochondria are known as the ‘powerhouses of the cell’. Other than this function, mitochondria are associated with certain cell-specific functions as they contain RNA (ribonucleic acid) and DNA (deoxyribonucleic acid). The small circular DNA present in mitochondria is known as mitochondrial DNA (mtDNA). The total mtDNA genome accounts to about 16,000 base pairs, which contributes only a fraction of the total DNA content (about 1 percent) in a cell. Let’s take a look on how mitochondrial DNA is used in forensic studies.

How is Mitochondrial DNA Used in Forensics

As per forensic science is concerned, investigators left no stone unturned, while solving cases. DNA-based technologies have been used to identify victims of a crime. In such methods, the DNA sequence of individuals or samples available from the crime scenes, also known as DNA fingerprint, is scanned to identify the victim. Most popular and effective DNA technologies that are used in forensics include RFLP (restriction fragment length polymorphism), PCR (polymerase chain reaction) and STR (short tandem repeat) analysis.

 

In case of very old biological samples, which are devoid of nucleated cellular material, mtDNA analysis is used. In recent times, the technique of mtDNA analysis is used to identify victims of cold cases, mass disasters (tsunami and earthquakes), historically important cases (war soldiers) and cases with limited biological material. Another advantage of mtDNA is that it can be isolated from samples like hair shafts, bones and teeth. Thus, investigators can study these samples by extracting mtDNA.

In comparison to extracting nuclear DNA, mtDNA isolation is more easy due to the presence of multiple copies in a cell. In humans, there are two copies of nuclear DNA (nDNA) in a cell; whereas, the mtDNA copies range from 100-10,000 per cell (except in egg and sperm cell). Hence, very small samples can be tested for victim identification. In general, a mitochondrion contains at least 2-10 copies of DNA.

Since mtDNA is inherited from the mother’s egg cell, it can be used to establish the maternal lineage. In simpler terms, the mtDNA of both mother and daughter are same. Hence, mtDNA analysis serves as a valuable tool, while investigating the case of a missing person. The mtDNA from the unidentified remains can be compared with the mtDNA profile of a maternal relative (such as brother and sister, mother and her daughter). If the mtDNA profiles of the two individuals match, then they are relatives. Thus, any maternal relative will be able to provide a reference sample.

How is Mitochondrial DNA Used in Forensics

These are many advantages of using mtDNA as a crime-solving tool in forensic studies. The mtDNA, because of its circular structure and location inside the cell, is more stable and strong than the nuclear DNA. It is shown that mtDNA is protected from degradation, even when exposed to prolonged environmental conditions, which is not the case with nDNA. This is the reason why, mtDNA is present even in older and degraded specimens, whose nDNA is already degraded. The only limiting factor of mtDNA analysis is that there is little discrimination between the mtDNA sequences of the same maternal lineage.

Get To Know Forensic Nursing

What you can expect as a forensic nurse

Forensic nursing could be described as a combination of nursing care and criminology. It merges nursing science with the investigation of accidents, major injury or untimely death. Many times the crimes involve sexual abuse, so a fair amount of compassion and emotional stability is needed. The American Nurses Association officially recognized this specialty in 1995.

Recent popular TV shows like CSI brought forensic nursing into our living rooms. The characters are glamorized with fashionable clothes, palace-like laboratories and action scenes which are virtually non-existent in the real world.  Yet the evidence collection, analysis of physical and emotional injuries and playing advocate for those that have no support is what draws RN’s to forensic nursing. Forensic nurses are patient advocates and as such are called into courts to testify on behalf of their patients especially in cases of sexual abuse (SANE).



Nice Observations of Forensic Nursing

One daunting aspect may be the appearance in court settings.  This career is intertwined with law adn court cases, so one would have to expect to testify to the findings and relating “state-of-mind” of victims.  There could also be community pressure coming from lawyers, family members and the justice system itself, so a good moral compass will keep you clear of obstacles.

Typically at least a year of additional course work is required to be certified.  Most nurses work full time and attend classes off shift or take it at one of the premier online universities.  The financial rewards are higher as well with an expected 15-35% increase in hourly wage or salary.  With a shortage of nurses in nearly every city, the wage disparity may grow as well as the flexibility of on call or name your shift.

So take that RN, combine it with advanced training plus a large dose of empathy and you may make a perfect forensic nurse!


What Is Forensic Nursing
Forensic Nursing is one of the newest specialty areas recognized by the American Nurses Association. It involves working with law enforcement officials to aid in the investigation of crimes such as abuse, accidental death and assault.

Nursing Blog – How Do I Become A Forensic Nurse(with Rn,bsn)?

To begin working toward your forensic nursing degree you need to first be a registered nursing (RN). Most nursing schools with a forensic nursing degree program offer 2-year graduate-level courses awarding a Master of Science in Nursing.

Basics on Forensic Dentists

 

Odontology, or forensic dentistry, is an exciting specialization within the field. This career path involves the application of dental science to physical and biological dental evidence. Odontologists participate in autopsies, conduct dental examinations and use both physical and biological evidence to determine and/or support the crime theory.

 Find Your Forensic School Here! 

Many times an odontologist is called in to ID and confirm the remains of a missing person or victim where other evidence, such as fingerprints, are no longer available.  The process uses dental records, prior photographs and even computer reconstruction to validate the findings. 

Occasionally, items at the crime scene will also need exam and cataloging such as food, towels, clothing and toys.  Each may be proof of a person actually being in a given place, and combining with other forensic specialties, can formulate enough evidence for conviction.

In case of abuse or rape, forensic dentists will take pictures of victim’s wounds for permanent files.  With accurate scaling, these can be used to match an alleged perpetrator ‘s dental pattern and prove or exonerate him/her.

Doc explains the basics!

 

 

As far as careers, obviously one will have to go through dental school and then begin the process of specialization within odontology.  Check the professional board for more information:  American Board of Forensic Odontology .  Luckily, one can begin a normal dentistry career and begin work on specialization.

Forensic Facts and Reality

As you can see, forensics has been around far longer than the TV shows.  With the advent of significant technology advances, many cases are now solvable with limited evidence while old cases might be overturned or solved despite the time that has passed. 

A Question Of Forensics

The relatively new field of forensic science has radically changed the way law enforcement officials build their cases. Modern crime fighting is now the convergence of law enforcement, the judicial system, and science. Subsequently, it has changed the way policing in general and investigations specifically are conducted. Being caught red-handed need not mean at the scene or even hours later. In some cases, forensic science has solved cases decades after the fact.

Forensic evidence appears for the living too!

As the modern city began to take root, so too did the necessity of policing it citizens. During the late 1700s, the field we now associate with forensic science began to emerge from various scientific endeavors that evolved over the previous centuries. Soon, policing began to form its own set of codices regarding how it was conducted. With Fodere’s publishing of "A Treatise on Forensic Medicine and Public Health" the correlation between how people die and why the die took root.
In 1816, a laborer was successfully tried and convicted for the murder of a maidservant in Warwick, England. Hinged on matching the impression of corduroy fabric near the pond where the maidservant was drowned to the breeches of the laborer who was working nearby, the conviction was iron-clad.

When Carl Wilhelm Scheele pioneered a means of detecting arsenous oxide in corpses in 1876, the path was set towards establishing a means of verifying a cause of death in some corpses.
In her article for the New York Post, Katherine Ramsland states: "No one set standards or controls [for fingerprint matches]. In fact, more than 100 years after the first crime was solved with a fingerprint, no one completely has proved even the basic assumption: that everyone’s fingerprint is unique." Indeed, she adds: "Technically, forensic science is the application of scientific perspectives and methods to the investigative and legal process. However, it’s become an umbrella term that encompasses disciplines of skill rather than real science." Although forensic science is considered a legitimate branch of law enforcement, there is a great deal of controversy surrounding the veracity of the forensic method.

The average salary for forensic scientist employed by governmental agencies is about $50,000 for new graduates. A career tracking down the misdeeds of others is just a mouse click or phone call away. Regardless, a career in forensic science has become fashionable and lucrative. There is a substantial backlog of forensic cases across the country and the demand for qualified applicants is high.

Crime Lab History and Secrets

Forensics has lept into the western world’s consciousness with the populariity of shows such as CSI, NCIS and their regional versions in NY and Miami.  Despite all of the glamour, the roots were very humble and current labs leave the glitz behind.  Nonetheless, forensic careers are expanding and pay well until you reach the higher levels such as Medical Examiner. 

You have heard of crime labs where scientific testing takes place on the TV show CSI. How is a forensics lab different from a clinical lab? How did a forensics laboratory come about? Where did it come from? What kinds of testing go on in a forensics lab?

 Find The Top Forensic Schools Here! 

Both forensics and clinical laboratories use the same scientific equipment and follow the same research protocols. However, in a clinical lab, testing with the purpose of diagnosing and treating the sick is carried out from a live patient. A forensics lab performs testing with the aim of establishing links between a suspect and a crime.

The Very First Crime Lab

In 1923, August Volmer (1876-1955) of the Los Angeles Police Department established the nation’s first forensic laboratory. About six years later, the first privately owned forensic lab was established in Chicago following the investigation of Chicago’s notorious St. Valentine’s Day Massacre. Calvin Goddard (1891-1955), America’s leading firearms identification expert at the time, was able to deduce a connection of the killings to Al Capone. Because of his expertise in firearms identification, two businessmen saw a potential in Calvin Goddard and funded further development of his crime lab at Northwestern University where he became a professor of police science. This new lab enveloped the other disciplines of blood analysis, fingerprinting, and trace evidence analysis under the same roof.

Then in 1932, Goddard helped establish a national forensics laboratory for the FBI. It is in this lab that nearly all forensic services known to law enforcement are performed. Today many states have used the FBI forensics lab as a model for their own state or local labs.

Common Procedures Done in a Crime Lab

Technical scientific analyses offered by modern-day crime labs and medical examiners’ offices are diverse and complex. The number of services supplied by a particular lab is inherently dependant upon its size and available funding. State and regional labs may provide a wide range of services, and local labs may provide only fundamental testing procedures. In general, small crime labs usually outsource more complex testing to larger regional labs. Moreover, the FBI’s National Crime Lab offers services to all law enforcement agencies all over the country. An FBI crime lab can perform just about every type of scientific test. It also has access to databases covering everything such as tire-track impressions, fingerprints, shoe prints, and postage stamps.

Larger laboratories may offer separate departments for each discipline, while smaller labs tend to encompass various services. Sometimes, there is an individual technician who is hired to do all the work. This is what the grunge character, Abby Sciuto, the forensics expert on the TV show NCIS, does. If this is the case, it would be smart for her to outsource the work to larger reference labs.

Crime Lab DNA Testing

What are the common procedures done in a crime lab?

•Fingerprint analysis

•Tool mark and impression analysis

•Blood analysis

•Ballistic reports

•Trace evidence reports

•Toxicological testing

•DNA analysis

No doubt, a crime lab technician has his work cut out.

With advancing technology, there will be newer services offered for crime labs all over the country. This will make it harder for perpetrators to get away with murder, bank robbery, or sexual assault.
