"We now have the ability to label cells based on expression profiling of sequence-specific transcription factors," said corresponding author Chrissa Kioussi, pr...
Robots grow mini-organs from human stem cells
May 21, 2018 (SPX)
The advance promises to greatly expand the use of mini-organs in basic research and drug discovery, according to Benjamin Freedman, assistant professor of medic...
Ultrasound helmet helps image the brain, tap into neural networks
May 16, 2018 (UPI)
"But it's been mostly ignored for the last decade," Brett Byram, an assistant professor of biomedical engineering at Vanderbilt University, told UPI. It's not b...
Mini tractor beams help arrange artificial cells into tissue structures
May 15, 2018 (SPX)
The team say that by altering artificial cell membranes they can now get the cells to stick together like 'stickle bricks' - allowing them to be arranged into w...
Microchips get under the skin of technophile Swedes
May 13, 2018 (AFP)
A tiny microchip inserted under the skin can replace the need to carry keys, credit cards and train tickets. That might sound like an Orwellian nightmare to som...
New CRISPR platform to make gene-editing more precise
May 08, 2018 (UPI)
