Large-surface articular cartilage defects can be cured with the cultured cartilage tissue (purple). 18.02.2010

Regenerative medicine: Cartilage growth stimulated

Researchers at the University of Freiburg are taking significant steps towards their goal of replacing damaged cartilage with newly cultivated tissue. With a clever trick, they have encouraged the body to produce new cartilage for itself.

The malaria parasite Plasmodium falciparum infects red blood cells before using them as a breeding ground for their own propagation. 15.02.2010

Protein database - a new weapon against malaria

To combat malaria, the parasite must be first understood in its entireity, thinks a group of scientists in Hamburg. This is why they have painstakingly created a database of all the 2500 proteins found in Plasmodium falciparum.

Following extensive RNA interference testing, scientists have identified new host cell factors that are critical for influenza A infection. Pictured here are viruses destroying a human lung cell 18 hours after infection. 26.01.2010

RNA interference signals new strategy against flu

Flu viruses are extremely versatile, making them difficult to combat. Research by scientists in Berlin could point towards new approaches in the treatment of influenza.

Chalcid wasps are parasites that inject their eggs in to fly larvae. An international team of researchers has now discovered that their own genetic material has been altered by parasites. 19.01.2010

Gene transfer: Bacterium propagates in the wasp genome

In global cooperation, researchers have decoded the genome of the Chalcid wasp. In the genome of the parasitic insect, they found traces of an altogether different kind of freeloader.

A German-American research team has presented the first genome encyclopaedia for every species of microbe on earth. 13.01.2010

Comprehensive encyclopaedia of microbe genomes

Nearly one thousand bacterial genomes have been decoded to date. These only cover a tiny area of the entire bacterial family tree, however. A German-American researcher team is hoping to change this state of affairs. In a mammoth project, the genomes of 56 extremely different members of the bacterial world have been fully deciphered.

All six of these Arabidopsis plants carry a different mutation in their genes. Tübingen-based researchers have made the first measurements of how quickly these hereditary changes actually take place. 11.01.2010

Tremendous pace of evolution surprises plant researchers

Changes in the genome are the engine of evolution. Researchers from Tübingen have made the first accurate measurements of how quickly mutations occur in the plant genome. The results are much quicker than was previously assumed.

Shown symbolically in the illustration are some of the complex metabolic and protein networks in Mycoplasma pneumoniae. 07.01.2010

Simplest bacterium reveals basics of life

A German-Spanish research team has fully characterised one of the world’s simplest living creatures. In the search for the fundamentals of life, they have concluded that simple does not necessarily mean simplistic.

Even years after successful treatment, breast cancer cells can cause metastases in the brain such as these shown here. Munich researchers have now observed the process in real-time. 30.12.2009

New insights: Observing metastasis in real-time

Metastases can form in the brain even years after the successful treatment of a tumour-related disease. Munich researchers have now observed this previously unexplained process in real-time.

If five copies of the tiny snowman created by the UK nanoscientists were placed side-by-side, the whole row would only be as wide as a human hair. 23.12.2009

Christmas Greetings from the Nanolaboratory

British scientists have created the world’s smallest snowman. And with this seasonal piece of news from the world of nanotechnology, we are off for a well-deserved holiday. We wish all our readers a Merry Christmas!

The Regent grape variety is particularly resistant to fungi. The decoding of its genome will help bring these characteristics to other varieties. 19.12.2009

Genome decoded of the first mildew-resistant grape variety

The genome of the grape variety Regent has been decoded. Because it is fungus-resistant, the researchers hope this will aid the breeding of new grape varieties.
