ASPD is a mental disorder characterised by several psychological and behavioural phenomena, including a lack of empathy and remorse, a low tolerance for anxiety, and shallowness.
People with ASPD prefer action to thought, and pathological lying, cheating, stealing, physical aggression and drug abuse are not uncommon. To be diagnosed with ASPD, the individual must have developed this behaviour before the age of 15, and as such is qualitatively different from the idea of a scheming, dishonest business person or politician, unless the behaviour began earlier in life.
For this research, 36 male inpatients of a maximum-security state forensic psychiatric facility were studied by psychiatrists from the Michigan Center for Forensic Psychiatry (CFP). Around half of the subjects had been admitted because they were found to be unfit to stand trial and the other half had been found not guilty by reason of insanity.
Of the patients studied, 15 had tattoos and 17 were diagnosed as having ASPD. Of those with tattoos, 11 of 15, or 73%, had ASPD, whereas only six of 21, or 29%, of those without tattoos had the same diagnosis. The research also uncovered an increased likelihood for those with tattoos to have previously suffered from sexual abuse, abused substances or to have attempted suicide.
“Our findings suggest that forensic psychiatric inpatients with tattoos are significantly more likely to suffer from ASPD than those without tattoos, and patients with ASPD were also significantly more likely to have higher numbers of tattoos, a larger percentage of their body covered with tattoos, and tended to have tattoos in more visible locations” said lead researcher Dr. William Cardasis, of CFP, Michigan. “I hope that this provides clues for clinicians to look for ASPD in forensic psychiatric patients with tattoos, and also to look for signs of suicide attempt, substance abuse, and sexual abuse.”
“One should keep in mind that the population studied was only a small segment of the population, and not indicative of what may or may not be relevant in the general population” added Cardasis. “Other interesting questions which this research raises include whether adolescents with tattoos are more likely to conduct disorder than those without, and what effect the meaning and subject content of the tattoo has.”

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
