In glass tubes standing metres high, the drug artemisinin is produced via the irradiation of a biotechnological intermediate. The pharmaceutical company Sanofi has constructed a new plant in Italy, which will be dedicated to the product. 02.05.2013

Using synthetic biology for antimalarials

The highly effective malaria medicine artemisinin is now being biotechnologically produced for the first time on an industrial scale. It is a prime example of the potential of synthetic biology.
A worker bee with bulging pollen sacks. These bees carry the pollen to the hive, where is it is processed into jelly for the larvae. 12.04.2013

GM corn: pollen does not harm bees

Genetically modified corn pollen has no harmful effects on honeybees. This is the finding of researchers in Würzburg following a series of insect field trials.
A man-made spider silk web: The company Amsilk is the first to produce threads from bioengineered spider silk. The extremely durable and tear-resistant material is destined for use in high-tech textiles. 19.03.2013

Lab-spun threads from spider silk

The company Amsilk has successfully converted bioengineered spider silk into fibres. Like its natural counterpart, the substance is extremely durable and ideal for application in high-tech textiles.
The composition of the chromosome set of the HeLa cells. Instead of the usually two sets per chromosome, many contain three or even only one. The coloured points indicate further modifications in the DNA when compared to the standard genome of human cells. 13.03.2013

Scientists’ favourite cell line deciphered

Of all the cell lines, the HeLa cells are regarded as the robust workhorses. Now, researchers in Heidelberg have finally sequenced the genome of the oldest human cell line.
The researchers studied the molecular basis of Parkinson's using reprogrammed cells taken from patients. 08.03.2013

Parkinson’s cells cured in the lab

Using highly accurate genetic engineering techniques, German stem cell researchers have successfully corrected a genetic defect that results in Parkinson's.
Actual mother-of-pearl.The crystallisation of specific types of lime can selectively regulated with the help of the green fluorescent protein. Among other things, this can be used to make the shiny mother-of-pearl found on the insides of sea shells. 22.02.2013

Mother-of-pearl from the protein laboratory

Microbes that can produce mother-of-pearl: researchers in Saarbrücken are now one step closer to this vision. Throughout, the green fluorescent protein has been a vital contributor to the project.
Using sterile paper tips, the dentist removes microbial samples from between the teeth. On a chip, the sample is tested for the presence of eleven periodontal pathogens. 31.01.2013

Quicker microbe checks at the dentist’s

Fraunhofer researchers are working on a chip that can quickly detect dangerous pathogens in the mouth. In just 30 minutes, the ‘ParoChip’ can uncover the eleven most important periodontal pathogens.
Only tumour cells with CD113 receptors (green) are infected and killed by the modified measles virus. Cells lacking the markers (red) are spared. 23.01.2013

Measles virus hunts down tumour stem cells

Researchers at the Paul Ehrlich Institute have been modifying measles viruses to infect and kill cancer stem cells. In the course of their work they have completely suppressed tumours in mice with liver cancer.
The survival artist Norovirus: A new version of the pathogen pops around every two years. 10.01.2013

Norovirus: Sydney 2012 on the up

Experts are anticipating a massive wave of the Norovirus to spread across Germany in months to come. Most people are not immune to the pathogen-variant ‘Sydney 2012’ and are therefore particularly vulnerable.
So-called TALE nucleases are increasingly used as gene scissors in research. 08.01.2013

Molecular scissors from building blocks

Automated laboratory production of super-exact gene scissors – this is the promise of a process developed by molecular biologists at the University of Bonn.
