Engineers 3D Print a “Living Bacterial Tattoo”

MIT engineers devised new 3D printing technique that uses ink made from genetically programmed living cells. Printed layer by layer, cells, and nutrients in hydrogel form three-dimensional, interactive structure. They light up in response to a variety of stimuli and turn into living devices.

Scientists Found a Way to Rejuvenate Old Human Cells

Slowing, stopping, or even reversing aging has always been an ongoing topic in science. Now, scientists used the synthetic compound resveratrol, found naturally in chocolate and other consumables, to turn back the biological clock in senescent cells, causing them to start dividing again.

Scientists Successfully Folded a Protein Within a Protein

A research group from Singapore has developed a bacterial protein nanoparticle shell which folds and protects recombinant proteins within it. A fundamental breakthrough in the rapidly expanding field of synthetic biology, this technology can improve yields of proteins with biological activity by 100-fold and shield recombinant proteins from heat, harsh chemicals and proteolysis.

Single Base Editing Is Now Possible With CRISPR

Researchers have reached a new milestone in CRISPR technology by building an enzyme that can directly transform a DNA base pair from an A-T to a G-C. It will allow for more precise edits than ever before, opening doors for “DNA surgeries” and correction of mutations that cause human diseases.

Scientists Develop Sound Wave FACS Technology

Researchers from Singapore have developed a highly precise single-cell sorting alternative to the popular FACS that uses focused sound waves instead of harsher electric fields. Their detection mechanism also shrinks the instrument size, reduces its complexity and substantially lessens costs. In addition, it enables more accurate cell  sorting and leaves no damage to target cells.
