Nanoparticles: shapeshifters that pass along the food chain and end up in the brain
Nanomaterials can pass much further along the food chain than was previously thought. The particles can change shape and size in each organism, enabling them to pass on to the next one in the chain. Researchers from the Institute of Environmental Sciences discovered this accidentally when using a novel…

Superselective bonds light up
Rather than one key and one strong lock, biology often uses tens or hundreds of weaker links to bind parts together, such as cells membranes. This allows for selectivity and also reversibility: the binding can also be undone. Researchers first caught this phenomenon using spheres or colloids, and published…

A unique defence: Bacteria lose cell wall in the presence of virus
Bacteria temporarily live without their cell wall if dangerous viruses are near. A remarkable feature, as the cell wall is a sturdy barrier against threats. Still, the discovery has a logical explanation ánd might be of a consequence for fighting pathogenic bacteria, according to Véronique Ongenae,…

How cells talk by pulling on a fibre network
Mechanics play a larger role in blood vessel formation, and other developmental biology, than previously thought. Cells appear to respond to mechanical signals, such as pressure. Through the extracellular matrix, a network of fibrous proteins, cells can supposedly exchange those mechanical signals over…
