Harvard biologists have brought new meaning to the term "fine print" by devising microscopic tiles made of DNA that self-assemble into letters, Chinese characters, emoticons and other shapes. More than mere doodling , their advance, detailed this week in the journal Nature, could make it easier and cheaper to build tiny DNA devices capable of delivering drugs or aiding the study of biochemistry, scientists said. "This technique will accelerate the research field of DNA nanotechnology," said Ebbe Sloth Andersen, a researcher at Aarhus University in Denmark who collaborated on an editorial that accompanied the report.

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.

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.

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."

The Rev. Al Sharpton said he wants a DNA test to determine whether he is related to former segregationist Sen. Strom Thurmond through his great-grandfather, a slave owned by an ancestor of the late senator. "I can't find out anything more shocking than I've already learned," Sharpton told the Daily News. Professional genealogists found that Sharpton's great-grandfather, Coleman Sharpton, was a slave owned by Julia Thurmond, whose grandfather was Strom Thurmond's great-great-grandfather.

Last week a British biotechnology firm called Genostic Pharma filed a patent application for its version of a cutting-edge medical device called a DNA chip. DNA chips are fabricated from human genes, rather than silicon as in the case of computer chips. They are essentially electronic sensors used in laboratories to analyze samples of a patient's DNA and spot abnormal gene fragments that could predispose the individual to disease. DNA chips in themselves are not new. In Silicon Valley, Affymetrix Inc. has developed a chip that can detect whether people have genes predisposing them toward some types of cancer, thus giving them a potentially lifesaving chance to limit that risk through regular medical checkups and dietary changes.
