Better tissue healing with disappearing hydrogels

When stem cells are used to regenerate bone tissue, many wind up migrating away from the repair site, which disrupts the healing process. But a research team makes use of hydrogel polymers in keeping the stem cells in place, resulting in faster and better tissue regeneration.

Retina prosthesis - Making artificial vision look more natural

In laboratory tests, researchers have used electrical stimulation of retinal cells to produce the same patterns of activity that occur when the retina sees a moving object. Although more work remains, this is a step toward restoring natural, high-fidelity vision to blind people.

Cellular traffic control system mapped for the first time

The transport routes of nutrients and messenger cargos can be compared to the traffic system of a city: A worldwide unique quantitative study of cell biologists shows that cells regulate the main routes, side routes and intersections by an intricate traffic control system, which guides the spatial and temporal distribution of substances within the cell.

Environmental factors could explain when pollen proteins become allergens

The reason why many people are allergic to birch pollen has not been fully clarified yet. It is known that a specific birch pollen protein causes the immune system to overreact. What makes it an allergen has now been discovered by scientists at the Vetmeduni Vienna. The pollen protein can bind iron. Without iron load the protein becomes an allergen. Environmental factors are possibly the reason for low iron loads in plants.

Smart application of surfactants gives sustainable agriculture

Researchers have investigated the interaction between the plant's barrier, plant protection products and adjuvants that are added to increase the effect of the plant protection product. The results of this research can be applied to minimise the use of plant protection products in agriculture.

How the environment and genetics impact our DNA

The impact of the environment on our genetic makeup has long been a topic of discussion among researchers. Now a European consortium (EURATRANS) has taken the opposite approach. The scientists have investigated for the first time to what extent specific genetic predispositions influence the processes of gene regulation.

For the first time in the lab, researchers see stem cells take key step toward development

The gap between stem cell research and regenerative medicine just became a lot narrower, thanks to a new technique that coaxes stem cells to take the first step to specialization for the first time in a laboratory. Researchers demonstrated that not only is it possible for mouse embryonic stem cells to form three distinct germ layers in the lab, but also that it requires correct timing, chemical factors and mechanical environment.
