A most appropriate presentation

This is cool: Nobel laureate James Watson – co-discoverer of the DNA double helix and father of the Human Genome Project – today, in a presentation at Baylor College of Medicine, became the first human to receive the data that encompass his personal genome sequence.It’s astonishing how far we’ve come in genetics in such a …

Mini-DNA replicator

This is pretty amazing: A pocket-sized device that runs on two AA batteries and copies DNA as accurately as expensive lab equipment has been developed by researchers in the US. The device has no moving parts and costs just $10 to make. It runs polymerase chain reactions (PCRs), to generate billions of identical copies of …

Made-to-order DNA…

…is about to get a lot easier to create: Installing one of those prefab, snap-together wood-flooring kits is a lot easier than shaping and sanding rough planks. Adapting a similar construction strategy, a biotech startup called Codon Devices, based in Cambridge, MA, aims to streamline genetic engineering. It makes made-to-order DNA strands, freeing scientists from …

…when you’ve got DNA? Japanese scientists say it might be possible to use DNA to store text, images, music and other digital data for thousands of years inside living organisms. Masaru Tomita and colleagues at Tokyo’s Keio University say data encoded in an organism’s DNA, and inherited by each new generation, could be safely archived …

DNA fingerprinting

One place science and society frequently interact is within the courtroom. Seldom has that interaction been more dramatic than in the past few days, with the exoneration of Guy Paul Morin, who had served 18 months in jail for a murder he didn’t commit, and with the start of the murder trial of a certain …

Heredity

“She’s got her father’s eyes.” “He’s got his mother’s nose.” From the moment a baby is born, expect children to look like their parents. But how does it happen? An Austrian monk named Gregor Mendel took the first step toward our modern understanding of heredity in 1866, when he published a theory of inheritance based …

The Human Genome Project

I’ve written before about the genetic code and how it writes a description of each of us using an alphabet of only four letters: the four bases that are contained in deoxyribonucleic acid (DNA), adenine (A), guanine (G), cytosine (C) and thymine (T). Every organism has different proportions of these four bases. Two strands of …

DNA

Our 26-letter alphabet often seems like a model of efficiency. Look at how much information can be encoded and passed on with it. Look at what Shakespeare accomplished with it. I’m particularly fond of it because my ability to manipulate it is what pays for my food and lodging and other necessities like new CDs. …
