Algae Batteries! →
Cellulose is an amazingly versatile molecule, it helps plants and algae store energy, it feeds animals of all shapes and sizes, it’s the main ingredient in paper, it’s being used to make biofuels, and apparently it can also hold an electrical charge, essentially making a tiny, flexible, biodegradable battery. Different plants and species of algae have cellulose with different...

Biomaterials Insight
There’s a neat set of articles in this week’s issue of Nature on biomaterials. From the editorial:
Biomaterials research has come of age. Since antiquity, humans have been taking whatever substances are at hand — natural materials, glass, metals or polymers — and using them to replace body parts that have been damaged by disease or injury. But it is only recently, with the advent of...

Electronic Noses
Biomimetic electronic noses are designed to mimic the olfactory system of mammals, with receptors that respond to certain chemicals, sending an electronic signal to a computer that can integrate the responses in order to identify the odorant. These systems are useful in industrial food preparation, where contamination by microorganisms must be detected as soon as possible. A fascinating new...

Biology is Technology
Rob Carlson’s forthcoming book (<- Amazon link for pre-order), Biology is Technology: The Promise, Peril, and New Business of Engineering Life now has a blog with the first chapter posted online! It’s fascinating so far, I’m really looking forward to reading the rest!

Plasmid Purification Technology
Purification of plasmids, circular pieces of DNA that replicate independently from the chromosome and can be engineered to carry and express any desired gene sequence, is a fundamental technique of synthetic biology and something that we take for granted in our lab. We use commercially available (and relatively expensive) kits that have been optimized to get a lot of DNA out of bacterial cells...

One Thousand Microbial Genomes
GenBank, the central public database for genomic information, just completed its thousandth microbial genome. An interesting Nature News article discusses how this isn’t nearly enough for many evolutionary scientists and microbiologists. According to one scientist: “There have been four billion years of evolution and we can really benefit from having some of that information in our...

What is "boyish" anyway?
There’s been a lot of news today about a new study (that I can’t find online yet), reporting that prenatal phthalate exposure can make young boys act more “feminine.” Phthalates are chemicals found in some plastic products that have been shown to affect the endocrine system in rats, mimicking the effect of exposure to estrogens. The new study found that “Boys exposed...

There’s an excellent set of articles from Gizmodo this week “exploring the enhanced human future,” including:
-an interview with Michael Specter, “Synthetic Biology: Why Not Pursuing Crazy Biotech is dangerous”
-an article about tissue engineering and skin grafts: “Meat Band-Aids and Mass Production of Living Tissue”
-human/machine interfaces to...

Google Maps for Metabolism
A really neat new web-based metabolic network viewer was presented in today’s PLoS ONE: “Pathway Projector: Web-Based Zoomable Pathway Browser Using KEGG Atlas and Google Maps API.” This is, for me, one of the most useful and intuitive new software systems for biological research. Through an easy to use web interface, you can search for and zoom in on specific metabolic reactions...

Last week there was an interesting discussion over at the Slate Book Club beetween Michael Specter, author of the new book “Denialism: How Irrational Thinking Hinders Scientific Progress, Harms the Planet, and Threatens Our Lives” and Chris Mooney that specifically talked about how to educate people about synthetic biology to prevent the irrational denialism that has affected other...

Data Frenzy
Last night I went to see Ryoji Ikeda’s datamatics at Sanders Theater at Harvard and it was AWESOME. From wikipedia because I find it hard to describe (that’s Nick’s job), Ikeda:
is a Japanese sound artist who lives and works in New York City. Sometimes harsh, sometimes remarkably gentle, Ikeda’s music is concerned primarily with sound in a variety of “raw”...

iGEM Blogpost Roundup
Adam Bluestein:
One evident advantage of this compressed evolution is the opportunity, at iGem, for young students to engage directly with the Edisons of synthetic biology, sharing big ideas, tricks of the trade, and free sandwiches with the likes of Tom Knight, Randy Rettberg, Drew Endy, Pam Silver, and George Church (to name a few). How motivating must that be?
Rob Carlson:
iGEM is, at its...

Gene-makers put forward security standards :... →
Several gene-synthesis companies yesterday finalized a code of conduct that outlines how to screen orders for synthetic DNA that could be used for terrorist activities.
The code, which has been in the works from the International Association of Synthetic Biology (IASB) in Heidelberg, Germany, for a year and a half, reflects for the most part what has become common practice in gene-synthesis...
