Starving cancer
Starving cancer
A research group has developed a new strategy to fight cancer. Blood vessels in the environment of tumours are killed with a new molecule which leads to the „starvation” of the tumour. Compared to currently applied treatments, this new strategy has a series of advantages. Modern cancer therapeutics produced by biotechnological methods, often are based on antibodies.

Finger malformation reveals surprise
Finger malformation reveals surprise
Explaining the diversity of leg shapes in the animal kingdom and hereditary defects in finger Scientists have discovered a genetic mechanism that defines the shape of our members in which, surprisingly, genes play only a secondary role.

Repairing UV damage in the skin
Repairing UV damage in the skin
Scientists have elucidated the mechanisms underlying the repair of UV-induced damage in DNA, which frequently causes skin cancer. The protein structures additionally determined by these researchers will improve our understanding of how the body protects itself against skin cancer. These studies lay the foundations for the development of a new class of anti cancer agents.

Enzymatic complex revealed
Enzymatic complex revealed
Researchers have now completed the three-dimensional structure of the ribosome from a higher organism. Ribosomes are cellular machines responsible for protein synthesis. Their structure will facilitate the development of drugs against bacteria, fungi or viruses. The machinery that reads genetic information within a cell and translates it into corresponding proteins, the so-called ribosome, is among the most complex cellular enzymes known in biology.

Profiler at the cellular level
Researchers have successfully incorporated a diagnostic biological "computer" network in human cells. This network recognizes certain cancer cells using logic combinations of five cancer-specific molecular factors, triggering cancer cells destruction. Yaakov (Kobi) Benenson, from ETH Zurich, has spent a large part of his career developing biological computers that operate in living cells.

Combating fungal diseases
Combating fungal diseases
Scientists have discovered a potential new approach for inhibiting the growth of pathogenic fungi. Ultimately, immunocompromised patients with fungal infections, in particular, could benefit from this work. As temperatures soar and more and more people cool off at outdoor pools, the incidence of so called swimmer's ear - an infection of the ear canal - also rises.

Holograms Reveal Brain’s Workings,
Like far away galaxies, powerful tools are required to bring the minute inner workings of neurons into focus. A team of scientists report how Digital Holographic Microscopy (DHM) can now be used to observe neuronal activity in real-time and in three dimensions—with up to 50 times greater resolution than ever before.

A closer look at cells
A closer look at cells
Many substances and nutrients are exchanged across the cell membrane. Scientists have developed a method to observe these exchanges, by taking a highly accurate count of the number of proteins found there. Proteins on the cell surface play an essential role in the survival of the cell. They govern the exchanges between the interior and the exterior.

Tackling tumors with iron oxide
Tackling tumors with iron oxide
Detecting cancer cells and destroying them, injecting drugs with extreme precision into diseased cells in the human body - these are just two examples of what scientists are attempting to accomplish using iron oxide nanoparticles.

Underground waters resist forced depollution
Underground waters resist forced depollution
An experiment has demonstrated the role played by micro-organisms in the degradation - without oxygen - of a very common pollutant: vinyl chloride. The traces of human industrial activity persist deep inside the ground. And sometimes for a long time! In Switzerland alone, the Federal Office for the Environment records no less than 50,000 polluted sites, including 4000 that have been declared “contaminated” and require clean-up operations.
