New bioprinting technique allows for complex microtissues

Bioprinting is currently used to generate model tissues for research and has potential applications in regenerative medicine. Existing bioprinting techniques rely on printing cells embedded in hydrogels, which results in ...

Machine sucks up tiny tissue spheroids and prints them precisely

A new method of bioprinting uses aspiration of tiny biologics such as spheroids, cells and tissue strands, to precisely place them in 3-D patterns either on scaffolding or without to create artificial tissues with natural ...

Has a new dwarf galaxy been found hiding behind Andromeda?

One of the greatest challenges of astronomy is locating objects in space that are obscured by the light of nearby, brighter objects. In addition to making extra-solar planets very difficult to directly image, this problem ...

Invisible matters: How dwarf galaxies may lose their light

(PhysOrg.com) -- A new study seeking to answer the question of why some galaxies are extremely dark compared with others may eventually help to explain the formation of all galaxies, according to researchers at the Harvard-Smithsonian ...

Cosmic Dance Helps Galaxies Lose Weight

(PhysOrg.com) -- A study published this week in the journal Nature offers an explanation for the origin of dwarf spheroidal galaxies. The research may settle an outstanding puzzle in understanding galaxy formation.
