DNA fingerprinting simplified

Agarose gel electrophoresis" Most teenagers wouldn’t have a clue what this scientific term means, but middle school student Andrew Trigiano knows the protocol inside and out. When Andrew was 12, his father Robert Trigiano, a professor at the University of Tennessee, was looking for an interesting science project for his son.


New cost-effective means to reconstruct virus populations

Researchers from the United States and Switzerland have developed mathematical and statistical tools for reconstructing viral populations using pyrosequencing, a novel and effective technique for sequencing DNA. They describe their findings in an article published May 9th in the open-access journal PLoS Computational Biology.


Chemical cousin of DNA for use as new nanotechnology building block

In the rapid and fast-growing world of nanotechnology, researchers are continually on the lookout for new building blocks to push innovation and discovery to scales much smaller than the tiniest speck of dust.


Scientists Clarify Mechanism of Epigenetic Inheritance

Although letters representing the three billion pairs of molecules that form the “rungs” of the helical DNA “ladder” are routinely called the human “genetic code,” the DNA they comprise transmits traits across generations in a variety of ways, not all of which depend on the sequence of letters in the code.


Researchers help build global reference library of DNA barcodes

Most of us are familiar with bar codes, those small black stripes with numbers below, known as the Universal Product Code or UPC label, that appear on commercial products. We scan them at the grocery store or to check a price, or have to cut them out and send them in for a rebate.


Charting the epigenome

Until recently, the chemical marks littering the DNA inside our cells like trees dotting a landscape could only be studied one gene at a time.


Reconstruction of biological history of Aldaieta necropolis

A research team from the Department of Genetics, Physical Anthropology & Animal Physiology in the Faculty of Science and Technology at the Leioa campus of the University of the Basque Country (UPV/EHU), and led by Ms Concepción de la Rúa, has reconstructed the history of the evolution of human population and answered questions about history, using DNA extracted from skeleton remains.


Yale scientists visualize machinery of mRNA splicing

Recent research at Yale provided a glimpse of the ancient mechanism that helped diversify our genomes; it illuminated a relationship between gene processing in humans and the most primitive organisms by creating the first crystal structure of a crucial self-splicing region of RNA.


Infant formula must contain DHA omega-3 and AA omega-6, say international experts

New recommendations published by international experts in the Journal of Perinatal Medicine state that infant formula should include DHA omega-3 and AA omega-6 to guarantee a correct eye and brain development.


Study hints at insights to come from genes unique to humans

Among the approximately 23,000 genes found in human DNA, scientists currently estimate that there may be as few as 50 to 100 that have no counterparts in other species. Expand that comparison to include the primate family known as hominoids, and there may be several hundred unique genes.


Tuatara, the fastest evolving animal

In a study of New Zealand’s “living dinosaur” the tuatara, evolutionary biologist, and ancient DNA expert, Professor David Lambert and his team from the Allan Wilson Centre for Molecular Ecology and Evolution recovered DNA sequences from the bones of ancient tuatara, which are up to 8000 years old.


Scientists report first 3-D view of anti-cancer agent

Researchers from the Indiana University School of Medicine and the Purdue School of Science at Indiana University-Purdue University Indianapolis have created the first three-dimensional image of how a well-established chemotherapy agent targets and binds to DNA.
