Microalgae biofuels may provide a viable alternative to fossil fuels. Algae efficiently use CO2 and can produce biomass very quickly. Some species can double their mass in as little as 6 hours. Such single-celled organisms are amenable to high-throughput techniques to evolve new strains, unlike terrestrial biomass sources like corn which can take years to modify.
Over the years, tomatoes have been selectively bred for qualities such as size and firmness for shipping purposes and appearance, but selection for flavor has generally been overlooked. Many of us find that the tomatoes we buy in the grocery store just don’t taste like they used to. In fact, often they don’t taste like much of anything. Comparing them to the delicious local-grown varieties we can find during the summer provides evidence for this conclusion.
