New York, November 4, 2016: Scanning people’s brains with functional magnetic resonance imaging, or fMRI, is significantly more effective way to spot lies than a traditional polygraph test, a new research has found.

The findings suggest that when it comes to lying, our brains are much more likely to give us away than sweaty palms or spikes in heart rate.

Polygraph, the only physiological lie detector in worldwide use since it was introduced in its present form more than 50 years ago, monitors individuals’ electrical skin conductivity, heart rate, and respiration during a series of questions.


Polygraph is based on the assumption that incidents of lying are marked by upward or downward spikes in these measurements.

The study, published in the Journal of Clinical Psychiatry, found that neuroscience experts without prior experience in lie detection, using fMRI data, were 24 per cent more likely to detect deception than professional polygraph examiners reviewing polygraph recordings.

It has been demonstrated that when someone is lying, areas of the brain linked to decision-making are activated, which lights up on an fMRI scan for experts to see.

“Polygraph measures reflect complex activity of the peripheral nervous system that is reduced to only a few parameters, while fMRI is looking at thousands of brain clusters with higher resolution in both space and time,” said the study’s lead author Daniel Langleben, Professor of Psychiatry at Perelman School of Medicine, University of Pennsylvania in the US.

“While neither type of activity is unique to lying, we expected brain activity to be a more specific marker, and this is what I believe we found,” Langleben noted.

To compare the two technologies, 28 participants were given the so-called “Concealed Information Test” (CIT).

CIT is designed to determine whether a person has specific knowledge by asking carefully constructed questions, some of which have known answers, and looking for responses that are accompanied by spikes in physiological activity.

In the controlled comparison of the two technologies, the researchers found that fMRI spotted more lies.

The approach adds scientific data to the long-standing debate about this technology and builds the case for more studies investigating its potential real-life applications, such as evidence in the criminal legal proceedings.

“While the jury remains out on whether fMRI will ever become a forensic tool, these data certainly justify further investigation of its potential,” Langleben added. (IANS)

The aim of the book is to teach children that families can exist in different forms, and show them how to accept the diversity in family backgrounds.

By Siddhi Jain

Delhi-based author Pritisha Borthakur is set to release her new book, 'Puhor and Niyor's Mural of Family Stories'. The 1,404-word children's book was put together to address a new kind of societal debacle in the family system. The author says the aim is to teach children that families can exist in different forms, and show them how to accept the diversity in family backgrounds.

The author who named the book after her twin sons -- Puhor and Niyor -- is a parent who has seen and heard the tales of ridicule and discrimination suffered by many in India and beyond. She says the book is an artistic illustration for kids that details how different families can live and coexist. Whether it's children with two dads or two moms, children with a single dad or single mom, and even multiracial family units, Borthakur's book teaches love, understanding, and compassion towards unconventional families.

Beyond race, gender, color, and ethnicity which have formed the bases for discrimination since the beginning of time, this book aims to bring to light a largely ignored issue. For so long, single parents have been treated like a taboo without any attempt to understand their situations; no one really cares how or why one's marriage ended but just wants to treat single parents as villains simply for choosing happiness and loving their children.

Homosexual parents, a relatively new family system, is another form that has suffered hate and discrimination for many years. Pritisha emphasizes the need to understand that diversity in people and family is what makes the world beautiful and colourful. 'Puhor and Niyor's Mural of Family Stories' is a firm but compassionate statement against all forms of discrimination on the bases of sexual identity, gender, race, and even differences in background

Clean and maintained hands boost confidence in daily life activities.

If you feel that clean and well-groomed hands are just an essential prerequisite for women, you might like to think twice. Men should equally pay attention to their hands because our hand houses 1,500 bacteria living on each square centimeter of its skin. You can easily assume what havoc it can create in our body because in India we have the culture of eating with our hands and spaces beneath nails can become breeding heaven for germs. Moreover, clean and maintained hands boost confidence in their daily life activities. Therefore, it's important to keep your hands clean irrespective of your gender by washing or sanitizing at regular intervals. And, to keep them groomed, you don't have to visit a salon.

Rajesh U Pandya, Managing Director, KAI India, gives easy and completely doable tips to follow at home:

* Refrain from harsh soaps: You should be mindful of the soap you are using to wash your hands. Your soap can have a moisturizing element in it like aloe vera or shea butter. Ensure that you're washing your hands with normal water as hot water can make your hand's skin dry and scaly.

Bitcoin has become an essential crypto asset in modern portfolios and investment funds.

Bitcoin has become an essential crypto asset in modern portfolios and investment funds. The confidence generated in this cryptocurrency will depend a lot on the diversification that companies make in their balance sheets in Bitcoin and the increase of institutional investors that allocate a percentage of their funds in this crypto. American fund manager Cathie Wood makes some interesting predictions, both in the rise that the Bitcoin price will experience in the next 5 years, suggesting these institutional investors allocate 5% of their funds; this will help leverage the Bitcoin market.
