Advances in 3-D printing have led to new ways to make bone and some other relatively simple body parts that can be implanted in patients. But finding an ideal bio-ink has stalled progress toward printing more complex tissues with versatile functions. Now scientists have developed a silk-based ink that could open up new possibilities toward that goal.
Researchers have developed a technique to build tiny models of human tissues, called organoids, more precisely than ever before using a process that turns human cells into a biological equivalent of LEGO bricks.
The motion of micro-organisms as they swim through various types of fluid channels show 'quite strange and new' responses for single cell organisms, including the performance of somersaults, meandering wanderings, and even a ballistic type of behavior.
Scientists have developed a nearly complete human brain in a dish that equals the brain maturity of a five-week-old fetus. The brain organoid, engineered from adult human skin cells, is the most complete human brain model yet developed.
Researchers have developed an image-based, cell-derived patterning strategy that produces arrays of homogeneous cells with anatomical properties that mimic the cells from which the patterns were derived.
New research demonstrates a new technology advancing the field of genome engineering. The method significantly improves the ability of scientists to target specific faulty genes, and then 'edit' them, replacing the damaged genetic code with healthy DNA.
A new study defines the core set of genes and functions that a bacterial cell needs to sustain life. The research, which answers the fundamental question of what minimum set of functions bacterial cells require to survive, could lead to new cell engineering approaches for E. coli and other microorganisms.
Using photosynthetically active microorganisms, researchers have succeeded in manufacturing several biocatalysts suitable for industrial application: a crucial step towards sustainable chemical processes.
