Bacteria help explain why stress, fear trigger heart attacks
Scientists believe they have an explanation for the axiom that stress, emotional shock, or overexertion may trigger heart attacks in vulnerable people. Hormones released during these events appear to cause bacterial biofilms on arterial walls to disperse, allowing plaque deposits to rupture into the bloodstream.

Read moreBetter 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.

Read moreResearchers find the mechanism that forms cell-to-cell catch bonds
Strong cell-to-cell bonds are important to heart health and fighting cancer. The bonds connecting heart cells have to withstand constant forces caused by continuous pumping. And, in some cancers, bonds no longer resist forces, allowing cancer cells to detach and spread.

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.

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.

Read moreEnvironmental 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.
