A Significant New Development In DNA Analysis Technology

The forensic examiners are working blind because they can't see the exact location which contains deposits of DNA

Australian scientists have developed a novel test which can reveal the amount of DNA people shed, an advance that would help forensic examiners catch criminals.

The test, using a DNA staining dye, can help forensic examiners at crime scenes determine the last person who made contact with an item.

“We know that some people pass on more of their DNA because when they touch something more of their cells are left behind,” said Adrian Linacre, Professor and Chair of Forensic DNA Technology at Flinders University, Australia.

“They are called shedders but it’s very difficult at the moment to see who is a shedder,” he added.

The shedder status of a specific person of interest may be relevant in determining the likelihood of whether a major contributor in a mixed DNA profile was the last person to make contact with an item and is therefore linked to a crime.

The use of a DNA staining dye can visualise the presence of cellular material and allow real-time collection of the cellular material to a swab head.

The results are published in the journal Forensic Science International: Genetics.

Forensic Examiners
Scientists have found a way of mapping out human DNA.

Currently, the forensic examiners are working blind because they can’t see the exact location which contains deposits of DNA and therefore have to sample where they think DNA might be stored.

“What we have developed is a simple test which can work out if an individual is a shedder in a matter of minutes. It tells us who has the better chance of passing on DNA,” Linacre said.

“The shedders test also showed men shed more than women do, and that thumbs leave the most accurate traces,” the researchers said. (IANS)

Although majority of Indians think their jobs would be automated in the next 10 years, 84 per cent hope to retain their jobs, supported by their skills, according to a report by World Economic Forum (WEF) and Ipsos.

India tops the list in terms of expectation of jobs automation, as around 71 per cent respondents expect their jobs to be automated. Saudi Arabia comes second with 56 per cent respondents expecting jobs getting automated, and in China 55 per cent respondents feel the same.

“Interestingly, 84 per cent of urban Indians polled are confident of keeping their jobs, using the skills they possess. The survey also shows across all markets, Indians are most confident, followed by the Netherlands (83 per cent) and the US (82 per cent),” the report said.

The markets least confident of holding onto their jobs in the face of automation, include Japan (23 per cent), South Korea (33 per cent) and Russia (50 per cent).

Commenting on the survey, Parijat Chakraborty of Ipsos India said, “Indian job market is hierarchy driven, promotions are skills and performance-led. Indians realise while automation is likely they know it will act as an enabler to improve efficiencies in deliverability; human intellect, skill-sets and capital will still be needed to get the job done.” (IANS)
