Freely Speaking: Programming Biology - Eric Clavins

Today's post refers to an inspiring talk by Eric Calvins who talks about programming the biology lab to program biological entities. I'll leave it to the reader to see what the implications of this vision are.

Focus on Algae - Part II: Energy

In the last focus section, we discussed how algae can be used to treat waste waters and mitigate CO2 in the process. Today's post will explore how algae can be used for energy generation. As already mentioned in the last time, biofuels have become very visible as of late due to environmental, economical and geopolitcal reasons. If at the heart of traditional biofuel generation lies in the creation and decomposition of biomass, then it would be easy to substitute corn or other less controversial land-based plants with algae. Although a lot of attention is paid to the use of algae in biofuel generation, and this article also mainly focusses on this aspect, it should be noted that algae can also be used to generate electricity by direct combustion of the biomass. Plans for these kinds of schemes are already on the way in Venice and a few other European locations [1].

Algae and Biofuels

What happens to the biomass after it has been created depends on the type of biofuel that is desired…

Sustainable Living: One man's trash...

Since Earth Week is starting tomorrow, I wanted share with you some concrete ways of how individuals like you and me can make an impact on a wider scale. I then also wanted to use this example to challenge everyone to think creatively about the larger context.

So you know how the saying goes: "One man's trash is another one's treasure." Today, I want to talk to you about garbage. Plastic garbage specifically. Plastic is quite a wondrous material. Made from oil by man with just a few additives can turn this polymer into so many different sorts of plastics with so many different properties from thin and flimsy plastic bags, to the carpet on which I am standing, to this plastic bottle from which I am drinking.

Focus on Algae - Part I: Bioremediation

After spending the last few blog posts on different aspects of dissimilatory bacteria, I want to switch the focus to a different class of organisms I have been interested in for a long time now. These are the algae. Algae comprise a large diversity of "sea weeds" and an even larger variety of single-celled organisms that mostly are capable of doing photosynthesis. They include the ordinary sea-weed, and make up a portion of the green slime found around the edges and the bottom of a pond. More exotic types of algae can live symbiotically - that is together with another organism in a mutually beneficial way. Lichens are an example of symbiotic relationship between algae and fungi. More information about the evolution and lineage of algae can be found in this wiki article.

Typically, these organisms are either not mentioned at all or only in conjunction with toxic algal blooms. But lately, algae, of course, have been in the news recently because of the promi…
