MIT chemical engineers and neuroscientists have developed a new way to classify neurons by labeling and imaging the proteins found in each cell. This type of imaging offers clues to each neuron’s function and should help in mapping the human brain, the researchers say. Says Kwanghun Chung, who is the Samuel A. Goldblith Assistant Professor… Read more

MIT researchers have developed a biomedical imaging system that could ultimately replace a $100,000 piece of a lab equipment with components that cost just hundreds of dollars. The system uses a technique called fluorescence lifetime imaging, which has applications in DNA sequencing and cancer diagnosis, among other things. So the new work could have implications… Read more

Bones are made up of tiny fibres that are roughly a thousand times finer than a human hair. One major feature of these so-called collagen fibrils is that they are ordered and aligned differently depending on the part of the bone they are found in. Although this ordering is decisive for the mechanical stability of… Read more

A new, onion-like nanoparticle’s innovation lies in its layers: a coating of organic dye, a neodymium-containing shell, and a core that incorporates ytterbium and thulium. Together, these layers convert invisible near-infrared light to higher energy blue and UV light with record-high efficiency. When it comes to bioimaging, near-infrared light could be used to activate the… Read more

Joint inflammation, or arthritis, is a common problem in medical practice and can be due to a variety of causes. Many types of inflammatory disorders affecting the joints belong to the diverse group of rheumatic diseases. The most common ones are rheumatoid arthritis and osteoarthritis which frequently affect the joints of the hands. These joint… Read more
