Scientists uncover the mechanism of fungal luminescence and create luminescent yeasts. Russian scientists with colleagues from the U.K., Spain, Brazil, Japan and Austria have fully described the mechanism of fungal luminescence.
They report that fungi utilize only four key enzymes to produce light and that transfer of these enzymes into other organisms makes them bioluminescent. Some living organisms can glow due to special chemical reactions in their bodies. Such organisms are called bioluminescent; they include fireflies, jellyfish and worms, among others. They use this ability to attract prey, scare away predators, communicate and disguise themselves. Scientists have identified thousands of species of luminescent organisms and about 40 chemical mechanisms to emit light.

Une pile à combustible convertit l'énergie chimique de combustion de l'hydrogène en énergie électrique.
Si elle est considérée comme un procédé propre – car elle ne rejette aucun gaz à effet de serre – la pile à combustible utilise néanmoins comme catalyseurs1 des métaux rares et coûteux, tel le platine, pour l'oxydation de l'hydrogène et la réduction de l'oxygène. Ces dernières années, l'identification de biocatalyseurs, des enzymes aux propriétés remarquables, a relancé très activement la recherche : leur activité de transformation de l'oxygène, mais surtout de l'hydrogène, est comparable à celle du platine. L'activité des hydrogénases était, jusqu'à récemment, inhibée par l'oxygène et donc incompatible avec une utilisation en pile.
Depuis plusieurs années, des chercheurs du laboratoire de Bioénergétique et ingénierie des protéines (CNRS/Aix-Marseille Université) développent une nouvelle génération de biopiles. Scientists Hacked a Cell's DNA and Made a Biocomputer Out of It. Our brains are often compared to computers, but in truth, the billions of cells in our bodies may be a better analogy.
The squishy sacks of goop may seem a far cry from rigid chips and bundled wires, but cells are experts at taking inputs, running them through a complicated series of logic gates and producing the desired programmed output. Take beta cells in the pancreas, which manufacture and store insulin. Meet the Revolutionary Apple That Grows Human Skin. What’s In An Apple?
Apples are a staple in most people’s homes and, it seems, in science. There was Newton’s apple, and the proverbial daily apple to keep your doctor away. Now, biophysicist Andrew Pelling of University of Ottawa wants to add an apple of his own into the mix — and this one might bring with it the future of biomaterials and human tissue repair. Many scientists thought the idea of this apple itself was a little fruity. Pelling said that his team did not have many cheerleaders when they started to look for ways to grow human cells by biohacking fruits. “Nobody else is doing this. How Pelling’s team achieved this was rather simple, he said. Synthetic Cells Have Passed A Turing Test. Fake It ‘Til You Make It Amid rapid advances in artificial intelligence (AI), humans use the Turing test to determine if a machine is truly intelligent.
If a computer is capable of thinking like a human, then it should be able to trick another human into thinking they’re having a real conversation with a person instead of a machine. In a twist on the classic test, scientists created artificial single-cell organisms able to convince natural cells that they are real. Programming Language Automates Generation of Plug-and-Play DNA. From the synthetic biologist’s point of view, living cells are biological computers, and the ultimate code isn’t binary, but tertiary, a stream of A’s, T’s, C’s, and G’s.
But tinkering with this code, so as to generate alternative or supplementary biological circuitry, has been tedious and time-intensive, requiring the manual assembly of parts and the trial-and-error balancing of potentially conflicting functions. In the programming of life’s code, unlike the programming of computer code, nothing like application programming interfaces, application generators, or even programming languages have been available—until now. Biological engineers based at Massachusetts Institute of Technology (MIT) report that they have created a programming language that allows even biology’s newbies to rapidly design complex, DNA-encoded circuits that give new functions to living cells. Dr. A programming language for living cells. MIT biological engineers have created a programming language that allows them to rapidly design complex, DNA-encoded circuits that give new functions to living cells.
Using this language, anyone can write a program for the function they want, such as detecting and responding to certain environmental conditions. They can then generate a DNA sequence that will achieve it. "It is literally a programming language for bacteria," says Christopher Voigt, an MIT professor of biological engineering. Goksel MISIRLI - Computational Design of Biological Systems. Synthetic Biology Comes into Its Own. Every two hours in Matthew Bennett’s Rice University lab, cyan and yellow lights flashed in synchronization.
Bennett and his team had engineered 12 components to generate the coordinated oscillations. This circuit wasn’t electronic, however; it was biological. Two populations of E. coli, each carrying a synthetic gene circuit, cycled in synchronous pulses every 14 hours. Bennett’s work, published last year in Science,1 is a key application of modern synthetic biology: taking biological components and linking them together to form novel functional circuits.
Why We Should Teach Kids to Code Biology, Not Just Software. Almost ten years ago, Freeman Dyson ventured a wild forecast: “I predict that the domestication of biotechnology will dominate our lives during the next fifty years at least as much as the domestication of computers has dominated our lives during the previous fifty years.”
Just recently, MIT researchers created a programming language for living cells that can be used by even those with no previous genetic engineering knowledge. Scientists have taken a huge leap toward creating artificial life. Even high-flying technology companies cannot avoid geopolitical risks. This was proved by Apple’s recent (and apparently unanticipated) run-in with Chinese authorities—including the sudden shutdown of iTunes Movies and iBooks in China. No matter how popular their products or how “borderless” their services, technology’s brave new world will increasingly clash with the older realm of borders and governments. As a result, both financial and physical costs will increase for tech companies and their customers. Programmable Plants: Synthetic Biologists Pave Way for Making Genetic Circuits.

Colorado State University scientists are creating this same modularity in – wait for it – plants, by designing gene “circuits” that control specific plant characteristics – color, size, resistance to drought, you name it. The relatively new, interdisciplinary field is synthetic biology – the design of genetic circuits, just like in electronics, that control different functions and can be easily placed in one organism or the next. Most of today’s synthetic biologists work with simple microorganisms, like E. coli or yeast. Amino: Desktop Bioengineering for Everyone.
Gene Editing Is Now Cheap and Easy—and No One Is Prepared for the Consequences. In April 2015, a paper by Chinese scientists about their attempts to edit the DNA of a human embryo rocked the scientific world and set off a furious debate. Leading scientists warned that altering the human germ line without studying the consequences could have horrific consequences. Geneticists with good intentions could mistakenly engineer changes in DNA that generate dangerous mutations and cause painful deaths. DARPA Wants to Genetically Engineer Organisms to Terraform Mars. There has been a lot of buzz in recent years about the possibility of mankind's big move to our nearest neighbor, Mars. Moving our species to the Red Planet also implies that we will be shipping over microorganisms, plants and maybe even animals. Review: the Emerging Field of Bioluminescence - Labiotech.eu.
Thanks to the synthetic biology revolution, bioluminescence is now moving from a curious natural trait to an interesting research field that could soon arrive to the market. Bioluminescence’s impulsors aim at replacing electric lighting. Sounds good, but which are the most advanced projects right now? Will bioluminescence really have an impact on the lighting market and when? Bioluminescence, the production and emission of light by a living organism, occurs widely in nature. This natural property was first observed hundreds of years ago. The Synthetic Biology Open Language (SBOL) Scientists Design Biological Safety Switch For GMOs. In a bid to reduce the risk of genetically modified organisms escaping into the environment and disturbing natural ecosystems, two groups of scientists in the U.S. have rewritten the genetic code of bacteria to produce strains that are totally dependent on unnatural substances to grow.
Not only do these organisms die without their synthetic food, but they are also resistant to viruses and unable to exchange their engineered DNA with natural counterparts. Although the techniques have only been used on bacteria so far, the researchers believe it may be possible to extend them for more complex organisms, such as plants.
