Pure-blood microchips
A tiny drop of your blood has enough DNA to diagnose or incriminate you - little wonder you demand a contamination- free analysis. As reported this month in Genome Research, Larry Kricka and colleagues from the University of Pennsylvania have constructed a microchip machine to take blood straight from collection to DNA analysis, without separate steps that could deplete or contaminate samples.

NIST genetics research lends a hand in World Trade Center IDs
Scientists and medical examiners have been working tirelessly since Sept. 11, 2001, trying to officially determined those who perished as a result of the terrorist attacks that day on New York City's World Trade Center.

Gag order: how DNA silencing can promote cancer
Methylation of genes effectively silences them, and excess DNA methylation, particularly of cell cycle genes, promotes cancer formation. Here, Rudolf Jaenisch and colleagues investigated DNA methylation in a mouse model of colon cancer. They found that a DNA methylating enzyme, Dnmt3b, targeted specific genes for silencing, and that these genes were similar to those silenced in human tumors. They believe that aberrant DNA methylation may be an initiating event in the development of cancer. (2011-04-01)

Children's Hospital & Research Ctr. at Oakland's DNA library helps to map the sex chromosome
Children's Hospital & Research Center at Oakland's DNA library was used to duplicate strands of DNA for an international team of scientists to generate the most complete analysis of the X chromosome. The landmark study is published in the March 17th issue of Nature. The human X chromosome is the most important chromosome for scientists to understand because the X chromosome is linked to more than 300 diseases - by far the highest proportion of any other chromosome. (2005-03-17)

Molecular machine shuffles beads on a DNA string
Yards of DNA are packed into cells by wrapping the DNA around proteins called nucleosomes. But that tight packing makes it hard for the cell's machinery to get at the DNA code to read, copy or repair it. Now researchers at the University of California, Davis, have shown how two proteins form a molecular machine that shuffles the nucleosomes out of the way to expose the DNA double helix. (2003-04-17)

Researchers identify abnormal expression of genes, resulting from DNA relaxation, that can be detected in the brain and blood of Alzheimer's patients. (2014-01-31)

DNA can be damaged by very low-energy radiation
That energetic particles damage DNA is not surprising. It is now appears that very low-energy OH radicals also damage DNA, with a propensity that depends on how vigorously OH rotates: rotationally 'hot' OH induce irreparable double breaks. These findings utilize OH formed in plasma created when intense IR femtosecond laser pulses propagate in water containing DNA. Industry characterizes as 'eye-safe' IR lasers. With such wavelengths being proficient at inducing DNA damage, how safe is 'eye-safe'? (2014-03-14)

Researchers have long sought an efficient way to untangle DNA to study its structure -- neatly unraveled and straightened out -- under a microscope. Now, researchers at KU Leuven have devised a simple and effective solution: they inject genetic material into a droplet of water and use a pipet tip to drag it over a glass plate covered with a sticky polymer. (2015-02-27)

Genome protects itself against mobile junk DNA
At the Hubrecht Laboratory in Utrecht, the biologist Sylvia Fischer has discovered how organisms protect themselves against transposons. Transposons are pieces of DNA which can translocate themselves within the genome. Sometimes transposons cause damage to the DNA. Plants probably have a similar mechanism which protects them against viruses. (2002-06-24)

Program predicts placement of chemical tags that control gene activity
Biochemists have developed a program that predicts the placement of chemical marks that control the activity of genes based on sequences of DNA. By comparing sequences with and without epigenomic modification, they identified DNA motifs associated with the changes. They call this novel analysis pipeline Epigram and have made both the program and the DNA motifs they identified openly available to other scientists. (2014-09-21)

Novel mechanism for DNA replication discovered
Since the discovery of the structure of DNA, the paradigm for DNA replication has stated that the DNA itself codes for replication. In other words, if a guanine base is on the original strand of DNA then its partner, a cytosine base, will pair to it on the replicated strand. Researchers from Mount Sinai School of Medicine report on the first instance in which a protein provides the coding information. (2005-09-29)

Maternal blood test is effective for Down syndrome screening in twin pregnancies
Cell-free DNA (cfDNA) testing, which involves analyzing fetal DNA in a maternal blood sample, is a noninvasive and highly accurate test for Down syndrome in singleton pregnancies, but its effectiveness in twin pregnancies has been unclear. A new analysis published in Ultrasound in Obstetrics & Gynecology reveals that cfDNA testing for Down syndrome in twins is just as effective as in singletons, with a detection rate of 98% and only a 0.05% rate of misdiagnosis. (2019-06-05)
