Using genetic engineering for efficient biofuel – a research group at the University of Graz is working to extract fuel from harvest waste. Her secret weapon is a yeast trimmed with fat.

Biodiesel, about Made of corn, the problem is that it is hardly economical. He is also criticized for using arable land, which could also produce food. Klaus Natter of the University of Graz wonders: why not solve both at once? If the (more…)

Researchers from Tübingen have developed a process that can be used to extract fuel for aircraft from hitherto largely useless acid whey. And all this without any chemical additives.

The organic oil produced from sour whey can be used as animal feed or aircraft fuel.

Of every liter of milk used in the production of quark, high-fat yoghurt or cream cheese, twice as much sour whey accumulates. Although this (more…)

Microbes can be genetically modified to be used for industrial purposes. The American start-up Zymergen has now received $ 130 million from the Japanese Softbank Group. And wants to expand the application possibilities for designer microbes. Thus, new materials such as adhesives or unbreakable plastics are to be developed.

Homepage Zymergen: The technology start-up uses robots and machine learning to develop microbes faster, more reliably and at an unprecedented level of performance.

Combining the benefits of proven building materials with living organisms: that’s the goal of a research project by the US agency Darpa. This would allow roofs to repair themselves, windows automatically seal against rain – and spare parts grow next door in the garden.

Researchers at the US agency Darpa want to use living materials in house or road construction.

Watching Explosive Detective Dogs: Soon you will face competition from grasshoppers. US researchers use electrodes to hijack the animals’ brains to use their sense of smell.

In the future, this cyber grasshopper will search for explosives. An electrode in the brain stores the odors the animal perceives with its sensitive antennae.

Curse or blessing? Genetically modified brewer’s yeast can actually produce the basic substance for morphine from sugar. That’s what US researchers found out. Production in the laboratory without opium poppy has thus come within reach.

So far, opium poppy is the source of reticuline - the basic substance of morphine. US researchers have found a way to handle this task of brewer's yeast.

Flowers that change color from day to day – that sounds like magic. Is possible. Petunias can do that recently. Researchers of an American start-up have prepared them accordingly. The project is looking for supporters on the crowdfunding platform Indiegogo.

American researchers are working on flowers that can change their color on command.

Bayreuth scientists have succeeded in producing an artificial biotechnological fiber that is just as resilient as the real silk of spiders. In addition, they have deciphered the process that ensures the great resilience of spider silk. Cobweb made of biotech spider silk.

Organs invisible to the naked eye have cultivated Berlin scientists. And there is also a simulated blood circulation. With the bred mini organs, side effects of new drugs and cosmetics can be more accurately determined than with animal experiments. This works with a newly developed biochip.

For the first time, researchers have bred nature-identical muscle fibers in the laboratory. This is to test drugs for their compatibility. The next goal is to use medicines that are tailored to each patient.
