Berkeley Lab Scientists Believe Biomanufacturing a Key to Long-term Manned Space Missions
Does synthetic biology hold the key to manned space exploration of the Moon and Mars? Berkeley Lab researchers have used synthetic biology to produce an inexpensive and reliable microbial-based alternative to the world’s most effective anti-malaria drug, and to develop clean, green and sustainable alternatives to gasoline, diesel and jet fuels. In the future, synthetic biology could also be used to make manned space missions more practical. (more…)
Stanford, CA — Plants spend their entire lifetime rooted to one spot. When faced with a bad situation, such as a swarm of hungry herbivores or a viral outbreak, they have no option to flee but instead must fight to survive. What is the key to their defense? Chemistry. (more…)
Berkeley Lab Researchers Develop New Tool for Making Genetic Engineering of Microbial Circuits Reliably Predictable
Synthetic biology is the latest and most advanced phase of genetic engineering, holding great promise for helping to solve some of the world’s most intractable problems, including the sustainable production of energy fuels and critical medical drugs, and the safe removal of toxic and radioactive waste from the environment. However, for synthetic biology to reach its promise, the design and construction of biological systems must be as predictable as the assembly of computer hardware.
An important step towards attaining a higher degree of predictability in synthetic biology has been taken by a group of researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) under the leadership of computational biologist Adam Arkin. Arkin and his team have developed an “adaptor” that makes the genetic engineering of microbial components substantially easier and more predictable by converting regulators of translation into regulators of transcription in Escherichia coli. Transcription and translation make up the two-step process by which the coded instructions of genes are used to synthesize proteins. (more…)
EAST LANSING, Mich. — American students need a dramatically new approach to improve how they learn science, says a noted group of scientists and educators led by Michigan State University professor William Schmidt.
After six years of work, the group has proposed a solution. The 8+1 Science concept calls for a radical overhaul in K-12 schools that moves away from memorizing scientific facts and focuses on helping students understand eight fundamental science concepts. The “plus one” is the importance of inquiry, the practice of asking why things happen around us – and a fundamental part of science. (more…)
A group of the world’s leading environmental scholars are sounding the alarm that human societies need to transform their national and international environmental institutions into a more coherent and robust planetary stewardship model to steer away from rapid and irreversible changes to the Earth’s subsystems.
University of Toronto political scientist Steven Bernstein is one of the authors of a paper which appears in Science on March 16, 2012. (more…)
*Joint BioEnergy Institute Researchers Develop CAD-Type Tools for Engineering RNA Control Systems*
The computer assisted design (CAD) tools that made it possible to fabricate integrated circuits with millions of transistors may soon be coming to the biological sciences. Researchers at the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI) have developed CAD-type models and simulations for RNA molecules that make it possible to engineer biological components or “RNA devices” for controlling genetic expression in microbes. This holds enormous potential for microbial-based sustainable production of advanced biofuels, biodegradable plastics, therapeutic drugs and a host of other goods now derived from petrochemicals.
