Assembly line for cell-sized microspheres

A production line for uniform lipid-coated microspheres has been created by Japanese scientists. Using a microfluidic device, the team can continuously generate fluid-filled vesicles that are all the same size and all have a single lipid bilayer surrounding them, and could one day be used in drug delivery or artificial cells.

Tiny rifts create fragility of brittle bone disease

According to researchers at MIT, a minuscule encoding error creates a defective collagen molecule that, at the site of the amino acid substitution, repels rather than attracts the collagen molecule alongside it. This creates a tiny rift in the tissue, which when repeated in many molecules, leads to brittle tissue, broken bones, deformity and, in the most severe form of the disease, death.
