3D printing stem cells to transform neuroscience

3D printing, also called additive manufacturing, has become widespread in recent years. By building successive layers of raw material such as metals, plastics, and ceramics, it has the key advantage of being able to produce ...

Teaching a computer program to track cells

Following the minuscule movements of every cell in a petri dish would be a painstaking task for any human. But teach a set of computer programs to do the job, and they can complete it quickly and even observe things that ...

Scientists identify networks for spikelet formation in barley

Organ development in plants mostly occurs through combinatorial activity of so-called meristems. Meristems are plant cells or tissues that give rise to new organs, similar to stem cells in human—including spikelets. Spikelets ...

Insight into the evolution of bones

A joint team of paleontologists has now for the first time analyzed bone structures in 400 million-year-old fossils of marine life at unprecedentedly high resolution and in 3D. To be able to view these structures, tomography ...
