A brief history of DNA Testing

Tuesday, June 23rd, 2009

brief history dna testing

As most any episode of CSI (= Les Experts) will tell you, DNA testing is a staple of modern crime investigations.

Since the advent of DNA testing in 1985, biological material (skin, hair, blood and other bodily fluids) has emerged as the most reliable physical evidence at a crime scene, particularly those involving sexual assaults. DNA, or deoxyribonucleic acid, contains the complex genetic blueprint that distinguishes each person. Forensic testing can determine if distinctive patterns in the genetic material found at a crime scene matches the DNA in a potential perpetrator with better than 99% accuracy.

As accuracy rises and costs drop, DNA analysis is becoming increasingly widespread. It’s familiar to daytime-TV fans as the leading method to determine paternity; do-it-yourself tests are now sold at drugstores in the USA.

What the World Didn’t See in Tehran

Tuesday, June 23rd, 2009

Shut out by the near totalitarian powers of the Islamic republic, the mainstream media tracked the stream of consciousness produced by new media. Some of the material is powerful, even indelible.

Particularly haunting is the 40-second YouTube video that shows a young woman, wearing jeans but otherwise dressed conservatively, suddenly falling to the sidewalk, shot in the heart. Her eyes turn to what must be a cell-phone camera, wide and shocked and dying as we stare at her. Men rush to her side and try to stanch the wound, but blood trickles from her mouth as an older man — later described as her father — cries and cries. Hours after the video surfaced, people on Twitter said she had not been part of the demonstration at all. Just a bystander.

By the end of the day, the Tweets had given her a name: Neda, which means “the voice” or “the call” in Farsi.

 

But who shot her? A soldier? A member of the notorious Basij, the volunteer militia that supports President Mahmoud Ahmadinejad? Were they aiming at her? Could this have been an accident or a random act of violence?

Twitter on the Barricades

Tuesday, June 23rd, 2009

This article deals with the links between political revolutions and communication tools.

Known collectively as Basijis, the brigades consist of officially recognized groups like Ansar Hezbollah, whose members undergo formal training, to smaller groups controlled by local clerics.

Social networking, a distinctly 21st-century phenomenon, has already been credited with aiding protests from the Republic of Georgia to Egypt to Iceland.

Iran : the “Twitter Revolution” ?

Twitter did prove to be a crucial tool in the cat-and-mouse game between the opposition and the government over enlisting world opinion. As the Iranian government restricts journalists’ access to events, the protesters have used Twitter’s agile communication system to direct the public and journalists alike to video, photographs and written material related to the protests. (As has become established custom on Twitter, users have agreed to mark, or “tag,” each of their tweets with the same bit of type — #IranElection — so that users can find them more easily). So maybe there was no Twitter Revolution. But over the last week, we learned a few lessons about the strengths and weaknesses of a technology that is less than three years old and is experiencing explosive growth.
