Made-to-Measure Medicines

2008-12-08 21:38:52

The concept of pharmacogenomics has been around for decades but only now in the age of the genome is true progress being made in its application. Pharmacogenomics is an understanding of the connections between our genetic make-up and our response to medication...

Neste Moves Forward with Green Diesel

2008-06-18 16:46:24

I have written periodically on 'green diesel', which should not be confused with biodiesel. Neste, Petrobras, and ConocoPhillips (in a venture with Tyson foods), have all entered the green diesel arena.

DNA Markers and Computer Science Methodology Can be Used to Trace Individual Ancestry

2007-10-01 12:57:19

Genetic markers (variations in the DNA among individuals) can be used to infer population structure, a task that remains a central challenge in many areas of genetics such as the study of population history and the search of susceptibility genes for common disorders. In such settings,...

Junk DNA: Let me Say it One More Time

2007-09-24 15:58:54

The term "junk DNA" was not coined on the basis of not knowing what it does. It was not a cop-out or a surrender. Susumu Ohno coined the term in 1972 in reference to a specific mechanism of non-coding DNA formation that he thought accounted for the discrepancies in genome size among species: gene duplication...

A Bio-Based Society?

2007-09-21 12:32:53

Biotechnology may not be the first thing people think of when asked for a solution to the major issues of our time such as pollution, global warming or the depletion of fossil resources. But here?s an interesting idea: what if we could step away from fossil fuels and started making products from renewable...

A Public Scientist in the Biotechnology Debate?

2007-09-14 13:02:36

Science and technology play an increasingly prominent and often controversial role in modern human society. From biotechnology and genetic engineering to computers, cell phones and nanotechnology, ordinary citizens encounter and even depend on science and technology in their daily lives. Yet most people...

I Didn't Notice I Lost a Gene

2007-07-27 09:49:41

In the year 2000, at around the time that the first human genome sequence was completed, an inventory of the genetic material of the small mustard plant Arabidopsis was published. Remarkably, although the total amount of genetic material in this small plant is only a fraction of that in humans, the...

Improve Upon Nature: Genetically Encoding Unnatural Amino Acids

2007-07-27 09:49:36

The building blocks of proteins in nearly all organisms are limited to 20 amino acids. It might be perfect for nature, but not ideal for scientists. We have developed a novel strategy to genetically encode unnatural amino acids in mammalian cells, including neurons,...

Are You Listening as Well as You?re Hearing?

2007-07-26 19:03:41

When we listen, we do more than just hear. We make sense of a complex sound environment. We?re so good at it that we take our auditory processing skills for granted ? until there?s a problem.

Biotechnology, A Science at Stake

2007-07-25 12:06:05

The 21st century could be the century of the sciences of the living organisms and of biotechnologies. They represent the seeds of a real revolution in the fields of medicine, food, industrial production and even environmental protection.

Genes and the development of obesity

2007-07-06 13:36:08

Obesity is one of the main health problems of our times, and it is estimated that it concerns nearly 300 million people in the world. Furthermore, the number of obese people is increasing. In the United States alone, the number of obese adults has increased by 10% in the last 10 years.

Genome Transplantation - Coming to a Bacteria Near You

2007-07-06 13:36:00

Well, I was interviewed yesterday by the AP (see the AP article here*) relating to an article in Science on Genome Transplantation by John Glass, Craig Venter, and crew and the Venter Institute. Their article is coming out in tomorrow's Science...

Deafness Research Has a Sound Future

2007-06-29 15:15:27

The inner ear contains six sensory organs, one auditory organ and five vestibular organs that subserve our sense of balance. The central players in all six organs are the mechanosensory hair cells which convert the mechanical stimuli of sound and head movements into electrical signals that are transmitted...

It?s All In the Packaging

2007-06-25 16:43:31

Remember how the best chefs pay as much attention to the packaging and presentation of a dish as the food itself. It turns out that the human genome believes as much in its packaging. Our DNA does not lie naked in the cell, but is wrapped up in proteins that constitute the packaging called chromatin...
