Genetics Breakthrough Gives Sustainable Biofuels A Big Boost. Researchers at the Enterprise Rent-A-Car Institute for Renewable Fuels at the Donald Danforth Plant Science Center have discovered a gene that influences grain yield in grasses related to food crops.

Genetics Breakthrough Gives Sustainable Biofuels A Big Boost

Four mutations were identified that could impact candidate crops for producing renewable and sustainable fuels. In a paper published April 18, 2017 in Nature Plants, a team led by Thomas Brutnell, Ph.D.Director of the Enterprise Institute for Renewable Fuels at the Danforth Center and researchers at the U.S. Department of Energy Joint Genome Institute (DOE JGI), a DOE Office of Science User Facility, conducted genetic screens to identify genes that may play a role in flower development on the panicle of green foxtail. Are microbes the next revolution coming to Big Ag? Walk into your typical U.S. or U.K. grocery store and feast your eyes on an amazing bounty of fresh and processed foods.

Are microbes the next revolution coming to Big Ag?

In most industrialized countries, it’s hard to imagine that food production is one of the greatest challenges we will face in the coming decades. Lab-Grown Meat Is Healthier. It's Cheaper. It's the Future. In Brief Since 2013, the price of lab-grown meat has dropped from around $325,000 for five ounces to just $11.36, making it 30,000 times cheaper than it was previously.Not only could lab-grown meat help us eradicate global famine, it's also better for the environment than traditional meat production.

Lab-Grown Meat Is Healthier. It's Cheaper. It's the Future.

Going Meatless The concept of lab-grown meat isn’t new, and several companies are hoping to perfect the process. Microbial Nanowires Make for “Green” Electronics. The inner workings of that new cell phone or tablet could be made from bacteria in the not so distant future, as investigators from the University of Massachusetts Amherst just reported about a new type of natural wire produced by bacteria that could greatly accelerate the development of sustainable "green" conducting materials for the electronics industry.

Microbial Nanowires Make for “Green” Electronics

In the new study, the researchers studied microbial nanowires—protein filaments that bacteria use naturally to make electrical connections with other microbes or minerals. “Microbial nanowires are a revolutionary electronic material with substantial advantages over man-made materials,” explained senior study investigator Derek Lovley, Ph.D., professor of microbiology at UMass Amherst. “Chemically synthesizing nanowires in the lab requires toxic chemicals, high temperatures, and/or expensive metals. ?articles. Researchers tweak bacterial proteins, turning them into powerful enzymes capable of producing silicon-carbon compounds naturally and more efficiently than manmade catalysts.


Silicone caulk, commercial sealants, are mainly composed of organosilicon compounds.WIKIMEDIA, ACHIM HERINGSilicon is one of the most abundant elements on Earth, and silicon-carbon compounds are crucial for pharmaceutical development and computer technology. Nourrir la « smart city » de demain grâce à l’agriculture cellulaire. L’agriculture cellulaire permet de reproduire des protéines animales sans recourir à l’élevage.

Nourrir la « smart city » de demain grâce à l’agriculture cellulaire

Une alternative pour répondre aux défis du secteur agricole et aux besoins alimentaires croissants liés à la démographie et à l’urbanisation. La population mondiale grandit inexorablement. Selon les Nations Unies, la planète comptera 9,7 milliards d’habitants en 2050. Et ce sont les villes qui accueilleront la majorité de la population. Si, en 1960, les citadins représentaient 34 % de la population mondiale, ils atteignaient 54 % en 2014. Les enjeux environnementaux sont également de taille. L’agriculture, premier secteur impacté, doit donc produire davantage, dans un contexte de restriction des réserves (épuisement des sols et des nappes phréatiques). La pression exercée sur la production animale donne naissance à une agriculture industrielle intensive, polluante.

" Le premier burger « in vitro » Fashion's Biological Future Is Now  In an industry notorious for transience, flux and experimentation, it’s counterintuitive to consider that the fashion system is stuck in a rut when it comes to materials and real sustainability.

Fashion's Biological Future Is Now 

Year after year, season after season, there’s this feeling of velocity, of working towards something better. Smartphones Could Soon Have Plant-Made Parts. Angela Belcher : Utiliser la nature pour faire pousser des batteries. Artificial Photosynthesis Yields Valuable Chemicals. Tiny semiconductors and bacteria have been combined to create a system that uses sunlight to turn carbon dioxide into valuable chemicals.

Artificial Photosynthesis Yields Valuable Chemicals

Photosynthesis forms the basis of most life on Earth. However, it cannot draw carbon dioxide out of the atmosphere fast enough to match the rate at which we are releasing what was stored over millions of years. Activation d'enzymes bactériennes pour convertir le CO2 en source d'énergie renouvelable. Exploiting Bacteria to Produce "Living Materials" A group of researchers at the Massachusetts Institute of Technology have unveiled a system whereby bacterial cells are engineered in such a way that they incorporate specific non-living materials into their biofilms, creating a "living material".

Exploiting Bacteria to Produce "Living Materials"

Biofilms are generated when bacteria cluster together and stick onto a surface. Often the bacteria will secrete substances that assist in this adherence, such as proteins and carbohydrate polymers (called polysaccharides) which form a slime. Microbes are "the factories of the future" Scientists Engineer Bacteria To Produce A Renewable Biofuel.
