DNA: Setting People Fee

Recently DNA has become a huge part of the criminal justice system, and how we catch criminals. From the tiniest trace of DNA, an individual's whole identity can be mapped out with amazing precision. Beginning in the late 80's DNA was playing a minor role in the criminal justice system, and it was only a little later, in the mid-90's, when DNA was being used to not only catch criminals, but also freeing the wrongly accused who have been sent to jail.

In 1986, a young white women was found raped and murdered near some train tracks in a black neighborhood. Due to the circumstances at which police had found the young women,  the case soon received national attention. After a few days, police detained, interrogated and arrested a 17 year old male, as well as a couple of his friends. The physical evidence that the teenagers had indeed killed the women, or were even near the scene, were thin in court. But relying on the testimonies of the few witnesses they had, the prosecutor had won all three cases, and the teenagers were sentenced to life in jail. 

However, years later, the three teenagers were building up their case of innocence in jail. DNA and seminal fluids taken from the crime scene was argued to have been at least one of the teenager's, but upon closer examination, it turned out that that was not true. The defendants had known that, but with such solid evidence against their sentence, why and how had they ended up in prison- for life? Eighteen months after writing a letter explaining their circumstances to Catherine Zellner, the teenagers had a retrial and, 15 years after being arrested, they walked out as freemen. If it wasn't for Zellner, who worked with Project Innocence, an organization focused on freeing the wrongly accused, convincing the judge of a trial using the DNA evidence, these men would have most likely never gotten out of prison. It also turns out that, after the two men who actually committed the crime confessed, the police had fabricated the whole story of the three teenagers. The police working the case had also fabricated eyewitness statements and the confession of one of the teenagers. But because of new DNA technologies, the teenagers accused of a crime they didn't do, walked out free men, 15 years after their initial arrest.

The idea that a tiny trace of DNA can reveal the whole truth of crime, is mind blowing. But if it means freeing people who have been wrongly accused of crimes, then I'm totally for it. Listening to this case has given me a new-found respect for my dead skin cells!

Be Happy, Be Healthy

Maybe you've heard the phrase "an apple a day keeps the doctor away", but what about "a laugh a day keeps the doctor away"?

 The idea that humor could actually affect the immune system has been a question on a lot of people's minds. In fact  in 2007 there was study conducted with 40 students to measure the correlation between laughter and health. They concluded the test showed no direct effects and more evidence was needed to be found.

Though they concluded what they did, I still find this pretty cool. It does make sense that laughter could have a positive impact on the immune system. With developing technologies in the world today, I'm sure the answer to this intriguing question is not far away. But for now I'll just stick to laughing 30 minutes each day.
