Silicon-based computers are fine for typing term papers and surfing the Web, but scientists want to make devices that can work on a far smaller scale, recording data within individual cells. One way to do that is to create a microscopic hard drive out of DNA, the molecule that already stores the genetic blueprints of all living things. Stanford University bioengineer Drew Endy is a pioneer in the field of synthetic biology, which aims to turn the basic building blocks of nature into tools for designing living machines.

"The Inborn Talent Genetic Test" promises to help parents identify their children's "hidden talents that may not be obvious at young age … it also reveals some personality traits that the child may possess, judging from his/her genetic make-up." Ever wonder if the marketing for DNA tests is getting a little out of hand? (Uh ... is the publishing industry threatened by the Internet?) Go to The Stuff of Life blog for examples of some iffy-sounding services. One of them is "The Inborn Talent Genetic Test," which "reveals the inherited and endowed inborn talents of a child scientifically from the genetic makeup of his/her DNA. The test result will therefore help parents identify their children's hidden talents that may not be obvious at young age … it also reveals some personality traits that the child may possess, judging from his/her genetic make-up."

President Obama may have given credence to a relatively new but questionable law enforcement practice that the rest of the developed world is starting to shun: taking and retaining DNA samples from individuals arrested for a crime but not convicted. That is, putting innocent people's DNA in criminal databases. During an interview with the president last month on the television program "America's Most Wanted," host John Walsh enthusiastically supported the expansion of this practice in the United States, saying, "We now have 18 states who are taking DNA upon arrest.

Authorities say they were able to use DNA evidence to track down a man who they say brutally beat and raped a 29-year-old woman in her apartment in 2012. The woman, who has not been identified, woke up at 6 a.m. Oct. 27 in her Rowland Heights apartment as Pablo Reyes Bautista, 26, attacked her, according to the Los Angeles County Sheriff's Department. The break in the case came when DNA recently entered by the suspect resulted in a match from a national database. Bautista was arrested "after an extensive manhunt" in Atwater Village, the department said.

Junk DNA may not be so useless after all. Scientists coined the term to describe the genetic wasteland within the human genome that consists of long stretches of DNA for which there was no known function. But researchers from Harvard Medical School said Wednesday that within junk DNA in the yeast genome they had discovered a new class of gene. It does not produce a protein or enzyme to carry out its function. But when it is turned on, it regulates a neighboring gene.

DNA evidence helped authorities nab a suspect in a Rancho Cucamonga murder nearly 17 years after the killing, authorities said Friday. Gabriel Bencomo was arrested Thursday in the Aug. 4, 1996, shooting death of Joseph Anguiano. Bencomo allegedly targeted Anguiano in front of Anguiano's home in the 8800 block of Hermosa Avenue. Anguiano later died at Loma Linda University Medical Center. The case remained unsolved until this week's development. The sheriff's cold case team reopened the investigation in 2010, combing through more evidence, according to officials.

It's interesting that people who support DNA testing are prosecutors, expert witnesses for prosecutors and people who own testing laboratories. Those who oppose it are scientists with good credentials. As a scientist--a pharmacologist--I believe that lawyers and police officers desperately want science to produce a magic bullet that will ferret out criminals. Unfortunately, many of those justice officials will grasp at any technology if they believe that it will help them win convictions.

State Atty. Gen. Jerry Brown has tentatively decided to provide police with partial DNA matches from California's offender database that would enable authorities to search for an unknown offender's relatives when all other leads in an investigation had been exhausted. The decision, expected to be finalized this month, means California would join at least eight other states authorized to do a form of familial searching in DNA databases. The goal is to find an offender through a relative in the database who has a similar genetic profile.

Inglewood police have arrested a Hawthorne man suspected of kidnapping and sexually assaulting four women waiting at the drive-through window of an El Pollo Loco restaurant during six months in 1995 and claim to have DNA evidence to link him to the crime. Darius Lamont Goodwin, 22, was charged last week with 21 counts of sexual assault, according to Inglewood Sgt. Bill Thompson.

New York City Police Commissioner Howard Safir outlined a controversial plan to take DNA samples from every person arrested in the city and create a database to speed the ability of police to solve crimes, identify repeat offenders and save costs. "We're not going to use it for anything other than identification," Safir said. "The innocents have nothing to fear. Only if you are guilty should you worry about DNA testing."
