When kidnappers assaulted a woman on a Guatemala City street and ripped her infant daughter from her arms, DNA testing came to the rescue. A positive match helped reunite mother and child after the baby turned up abandoned at a church with no identification.

In addition to identifying kidnap victims, DNA tests have helped connect adoptees with their biological parents and U.S. immigrants with their families.


Now, DNA technology is being called upon to bring together families separated at the U.S.-Mexico border.

Migrants’ advocates, however, say using genetic testing in this way raises technical, legal and ethical issues.

While several companies have offered to donate kits, leading migrant rights groups have turned them down.

Missing children

Genetic tests have helped an organization called DNA-Prokids reconnect more than 1,000 missing children with their families in Mexico, Nepal, Thailand and several other countries, including the kidnapping case in Guatemala City.

Jose Lorente, a professor of forensic medicine at the University of Granada in Spain, started the organization. Lorente said he was moved by the children he saw on the streets in cities around the world. Many were victims of trafficking and had parents who were looking for them.

Lorente said he hopes to establish a worldwide network of DNA testing labs to help children everywhere.

“This is a way to send a message to people trafficking children,” he said. “The message is, from now on, it is not going to be so easy to steal and traffic a child because he or she will be immediately identified.”

Border tests

Lorente said DNA tests could help make sure children coming across the U.S.-Mexico border are not being trafficked.

“It’s going to be a small percentage,” Lorente said, but added there may be cases in which ill-intentioned adults claim children who are not their own.

U.S. officials already use DNA tests to confirm that immigrants seeking to join relatives in the United States are related.

Genetic testing led the U.S. State Department to suspend a refugee program in 2008. Suspecting fraud in the family reunification program, officials tested about 3,000 applicants, mainly from Somalia, Ethiopia and Liberia. They confirmed a parental connection in less than 20 percent of the cases.

The program restarted in 2012, requiring a DNA test to prove that a parent and child are related.

New technology could enable those tests to be conducted at the border in as little as 90 minutes. Law enforcement agencies are evaluating rapid DNA tests that can match a person in police custody to a database of known criminals. The same technology could be used to test migrants.

Thermo Fisher Scientific has offered to donate $1 million worth of its rapid test technology to help reunite families separated at the border.

That followed offers from two ancestry companies, 23andMe and MyHeritage, to donate their technologies to the effort.

Privacy concerns

“Who’s going to keep that information?” asked communications manager Fernanda Durand with the migrant rights group CASA. She is worried the government could use migrants’ genetic fingerprints later without their consent.

“It’s very troubling,” she said.

Standard DNA tests can only reliably identify parent-child and sibling relationships. In refugee situations, advocates say, it’s not unusual for someone other than a child’s biological parent to care for him or her — for example, if a parent has been killed or detained.

The ancestry companies’ tests look at much more genetic information than standard DNA tests and can identify broader relationships; but, they can also generate much more sensitive data, including health information, and that would need to be protected. These tests also are not certified for this purpose by the organization that accredits DNA testing labs.

Plus, “Most of these migrants probably don’t have a high school education and have never encountered DNA in their lives,” noted genetic counselor Kayla Sheets, founder of Vibrant Gene Consulting. “How can they give informed consent [to be tested] if they don’t understand the technology?”

“This is a very, very vulnerable population,” Sheets added, and extra safeguards need to be in place when dealing with their genetic information. “And I’m just not certain that these companies, nor quite frankly the government, [are] quite set up for that yet.”

23andMe and MyHeritage say they are sensitive to the privacy concerns and will offer the tests only to legal aid groups working with migrant families.

Those groups have said, “Thanks, but no thanks,” according to communications director Jennifer Falcon at the Refugee and Immigrant Center for Education and Legal Services.

Separating parents from their children is bad enough, she said.

“We don’t believe you can solve one civil rights violation by creating another potential violation with their privacy,” Falcon added. (VOA)

Music is the universal language that is spoken by all.

When it comes to our day-to-day life, there are several things which help us enhance our day with every step. One such thing is music. It enhances, motivates and boosts certain aspects of our personality in ways that may not come into notice. There have been several researches on how music affects human brain. Studies show it helps us in recovery and healing, and also, encouraging us to be better if exposed to the right kind and fit.

From kids to elderly, music as a commodity, can be consumed by all. It is the universal language that is spoken by each and every being, from animals to humans to plants, each respond to it in their own ways. Suffice to say, we are united by music and the effect it has over us. Plants, for example, grow better when exposed to good music. Many songs are being composed specifically to enhance and boost their growth. Same is the case for humans. For humans, the right kind of music can boost good health, physically as well as mentally. You might have noticed how in gyms, upbeat music is played. That is to channel energy into everyone present. It adds to the workout. Several researches around the world have shown better physical output when exposed to appropriate music. Fast paced songs with upbeat nature channeled speed and the slower ones slowed downs the listeners, without them noticing. The sub-conscious effects of music are continuously being studied.

Awareness is the key to heal.

As more and more people are acknowledging the importance of their mental well-being, the wave of awareness the acknowledgment has brought is unprecedented. It may not have paved a clear path towards complete healing but it certainly has shown the way. The awareness is the key to heal. Healing begins only after the problem is identified. Similar to physical illness, the identification of the problem area is the first step. Even in case of a minor wound, when we go to the hospital the nurse first locates the wound. They, then, ask how we got hurt and identify the nature of the wound. Only then, they clean, put ointment and wrap it up if it needs wrapping and protection from air and dust. Sometimes, that protection is not needed. The wound heals out in the open. Same goes when it comes to healing of a mental trauma or illness. Sometimes, we confine in professionals or our loved ones, in order to let it out and process it openly. Sometimes, the trauma reduces with time. In any way, being aware and vigilant is the way to go.

Being knowledgeable about life in general, opens many channels for you. Being knowledgeable about yourself, opens gates inside you that lead to spiritual and general awareness about the concept of self. And the inner awareness is not necessarily internal, it can be seen from the outside as well. When we have positive energy from within it radiates physically as well. Have you encountered someone who’s spiritually awakened and aware? Do they stand out in the crowd? There are prominent examples of people who have made their mark in history, there is Swami Vivekanada, his awakening has revolutionised generations, one live example we can witness is The Dalai Lama.
