Comments Off on Breakthrough algae strain produces twice as much biofuel

Scientists have been working since the 1970’s to transform algae into biofuel . Now a new breakthrough could make this alternative energy source a more viable option. Researchers from Synthetic Genomics, Inc. and ExxonMobil were able to edit algae genes to produce two times more lipids. Those lipids can be turned into biofuel that isn’t too different from the diesel we use today. Researchers figured out how to tune a genetic switch to regulate the conversion of carbon to oil in the alga Nannochloropsis gaditana . They used multiple editing techniques including CRISPR-Cas9. They were able to boost the algae’s oil content from 20 percent to over 40 percent – and importantly, did so without stunting the algae’s growth rate. The modified algae can produce as much as five grams of lipid per meter per day.

Synthetic Genomics CEO Oliver Fetzer said carbon dioxide and sunlight are two major components necessary for algae production, and both are plentiful and free. According to ScienceAlert, a past report indicated biofuels from algae could become a $50 billion industry , with the potential to offer transport fuel and food security. But we still could be years away from pumping this particular algae-based biofuel into our cars at gas stations. Researcher Imad Ajjawi of Synthetic Genomics told ScienceAlert this step was just a proof of concept, but did describe it as a significant milestone. According to Greentech Media , organizations have been working on making biofuel from algae for years, without much progress towards commercialization. In fact, they cited former ExxonMobil CEO and current Secretary of State Rex Tillerson , who back in 2009 said the work on turning algae into biofuels might not come up with real results for 25 years. The journal Nature Biotechnology published a study on the concept online this month. Via ScienceAlert and Synthetic Genomics Images via ExxonMobil and Wikimedia Commons

MIT says science is close to cracking the genetic code that could eradicate Zika-spreading mosquitoes

Comments Off on MIT says science is close to cracking the genetic code that could eradicate Zika-spreading mosquitoes

Scientists at MIT are proposing the use of a controversial “gene drive” technology to wipe out the mosquitoes that carry the Zika virus , the rapidly spreading illness that causes babies to be born with small heads and brains. Three U.S. labs that handle mosquitoes are now working on developing the gene drive for the Aedes aegypti mosquito species, which also spread dengue fever and yellow fever. Researchers say the technology could be ready in as little as a few months, but they warn it will need to go through rigorous testing before it can be used to combat the disease-carrying insects.
