Scientists use inkjet technology to print 3D vascular system

Using direct-write assembly of organic ink, researchers have developed a technique for fabricating three-dimensional microvascular networks. These tiny networks could function as compact fluidic factories in miniature sensors, chemical reactors, or computers used in applications from biomedicine to information technology.

Metal ions may play a big role in how we sense smells

Of the five basic senses, the sense of smell is the least understood. Now, scientists have sniffed out potential clues to how olfactory receptors in the nose detect odors. Those clues may also explain why dietary zinc deficiencies lead to a loss of smell.
