Artificial cells demonstrate that ‘life finds a way’

Posted by in categories: bioengineering, biotech/medical, education, evolution

Evolutionary biologist Jay T. Lennon’s research team has been studying a synthetically constructed minimal cell that has been stripped of all but its essential genes. The team found that the streamlined cell can evolve just as fast as a normal cell—demonstrating the capacity for organisms to adapt, even with an unnatural genome that would seemingly provide little flexibility.

Details about the study can be found in a paper featured in Nature. Roy Z. Moger-Reischer, a Ph.D. student in the Lennon lab at the time of the study, is first author on the paper.

“Listen, if there’s one thing the history of evolution has taught us is that life will not be contained. Life breaks free. It expands to new territories, and it crashes through barriers painfully, maybe even dangerously, but… ife finds a way,” said Ian Malcolm, Jeff Goldblum’s character in Jurassic Park, the 1993 science fiction film about a park with living dinosaurs.

Robot skin heals

Researchers from the University of Tokyo pool knowledge of robotics and tissue culturing to create a controllable robotic finger covered with living skin tissue. The robotic digit has living cells and supporting organic material grown on top of it for ideal shaping and strength. As the skin is soft and can even heal itself, the finger could be useful in applications that require a gentle touch but also robustness. The team aims to add other kinds of cells into future iterations, giving devices the ability to sense as we do.

Professor Shoji Takeuchi is a pioneer in the field of biohybrid robots, the intersection of robotics and bioengineering. Together with researchers from around the University of Tokyo, he explores things such as artificial muscles, synthetic odor receptors, lab-grown meat, and more. His most recent creation is both inspired by and aims to aid medical research on skin damage such as deep wounds and burns, as well as help advance manufacturing.

AI combined with CRISPR precisely controls gene expression

Posted by in categories: bioengineering, biotech/medical, robotics/AI

Artificial intelligence can predict on-and off-target activity of CRISPR tools that target RNA instead of DNA, according to new research published in Nature Biotechnology.

The study by researchers at New York University, Columbia University, and the New York Genome Center, combines a with CRISPR screens to control the expression of human in different ways—such as flicking a light switch to shut them off completely or by using a dimmer knob to partially turn down their activity. These precise gene controls could be used to develop new CRISPR-based therapies.

CRISPR is a gene editing technology with many uses in biomedicine and beyond, from treating sickle cell anemia to engineering tastier mustard greens. It often works by targeting DNA using an enzyme called Cas9. In recent years, scientists discovered another type of CRISPR that instead targets RNA using an enzyme called Cas13.

Fabrication of Nanofiltration Membranes via Surface and Interface Engineering

Posted by in categories: bioengineering, chemistry, sustainability

A team of researchers successfully constructed nanofiltration membranes with superior quality using the mussel-inspired deposition methods. Such was achieved via a two-part approach to fabricate the thin-film composite (TFC) nanofiltration membranes. Firstly, the substrate surface was coated through fast and novel deposition to form a dense, robust, and functional selective layer. Then, the structure controllability of the selective layer was enhanced by optimizing the interfacial polymerization (IP) process. As a result, the properties of nanofiltration membranes produced are with high durability and added functionality. When put into a bigger perspective, these high-performance TFC nanofiltration membranes are potential solutions to a number of fields, including water softening, wastewater treatment, and pharmaceutical purification. Hence, there is a need to further explore and expand the application in an industrial scale instead of being bound within the walls of the laboratories.

Membrane-based technologies, especially enhanced nanofiltration systems, have been highly explored due to their myriad of distinct properties, primarily for their high efficiency, mild operation, and strong adaptability. Among these, the TFC nanofiltration membranes are favoured for their smaller molecular weight cutoff, and narrower pore size distribution which lead to higher divalent and multivalent ion rejection ability. Moreover, these membranes show better designability owing to their thin selective layer make-up and porous support with different chemical compositions. However, the interfacial polymerization (IP) rate of reaction is known to affect the permeability and selectivity of the TFC nanofiltration membranes by weakening the controllability of the selective layer structure. Therefore, this study was designed to improve the structural quality of the TFC nanofiltration membranes through surface and interface engineering, and subsequently, increase the functionality.

Researchers advance DNA nanostructure stability

Posted by in categories: bioengineering, biotech/medical, computing, genetics, nanotechnology

Researchers at the University at Albany’s RNA Institute have demonstrated a new approach to DNA nanostructure assembly that does not require magnesium. The method improves the biostability of the structures, making them more useful and reliable in a range of applications. The work appears in the journal Small this month.

When we think of DNA, the first association that comes to mind is likely genetics—the within cells that houses an organism’s blueprint for growth and reproduction. A rapidly evolving area of DNA research is that of DNA nanostructures—synthetic molecules made up of the same as the DNA found in living cells, which are being engineered to solve critical challenges in applications ranging from medical diagnostics and delivery to materials science and data storage.

“In this work, we assembled DNA nanostructures without using magnesium, which is typically used in this process but comes with challenges that ultimately reduce the utility of the nanostructures that are produced,” said Arun Richard Chandrasekaran, corresponding author of the study and senior research scientist at the RNA Institute.
