Breakthroughs in the science sector have been going on for years as scientists generate new ideas and jump conventional hurdles. A significant contribution to how far science has come today is in numerous technological advancements. Most of the bounds that science has made over the years has been aided by the presence of technologically superior machines and techniques. Cellular science is one sector that has benefited from different technological advancements. Some of these enhancements are not new, but continue to evolve with time as the demands for better approaches increase by the day.
The generation of genetic sequencing is an old technical enhancement that caused quite a stir in cellular science. Innovations made it possible for scientists to analyze the expression, structure, and functions of genes and facilitate the engineering of synthetic genes. What is impressive is that current state-of-the-art machines allow for the synthesis of longer strains DNA sequences. Novel techniques have also reduced the errors that occur during gene synthesis. Scientists are also constructing small genomes with the latest DNA gene synthesizing methods. Current enhancements allow genome sequencing at only a fraction of the cost and time it took just a few decades ago. It is expected that future technological advancements will allow engineering of entire biological pathways and the production of high-value compounds.
New investigations into the molecular levels of our body’s cells have brought about many technological and medicinal advancements as well. Laboratories and medical testing firms now use and test products like ASEA and ASEA Redox. Types of supplements like these use ingredients and technology to help our cells function at an optimum level. New technology is looking deeper into cellular messaging as well and hopefully more medicines and treatments can come about as a result.
Another area of cellular science that has experienced growth is with imaging tools. There is no doubt that microscopes are some of the greatest inventions in science because they allow scientists to see what they are working with inside the body. However, the fact that cells are colorless has left a lot of room for improvement in imaging tools. Some companies have already developed biological dyes and stains that enable scientists to evaluate the interaction of cells more clearly. Techniques such as spectral deconvolution are also used to complement the visibility of modern-day imaging tools.
MIT biological engineers have developed a way for human cells to store their own history, which is an analog memory. There have been other attempts to do the same, but those methods only indicated that an event has occurred. This new breakthrough shows how long a cell has been exposed to an event and the level of exposure. The CRISPR system, which is widely used for genome editing is what the scientists incorporated into the memory storage technique. They created a self-targeting guide RNA that directs the Cas9 enzyme to a newly mutated DNA. With this analog storage, scientists will be able to study how cells behave in certain environments, how they develop, and what triggers genetic changes.
CRISPR is one of the latest tools that scientists are using to tinker with genomes. CRISPR (Clustered regularly interspaced short palindromic repeats) refers to a configuration of DNA sequence pattern where repeats take place over and over again. Scientists noticed that the exceptional sequence matched that of viruses, meaning it had the power to recognize those viruses when they lodged an attack. CRISPR was combined with the Cas9 enzyme to form a system that could target a cell’s DNA and modify it. What this means is that scientists have the power to edit genes with a system that ensures precision, flexibility, and efficiency. The technology is a revolutionary achievement in gene editing and splicing. The CRISPR-Cas9 system had one downside in that the Cas9 enzyme caused undesired edits by cutting through sections that had not been targeted. Just recently, a group of scientists reported that they had worked out the kinks to get rid of off-target cuts.
Even with top-of-the-line technology, there are still some limitations that call for improvement; hence, proving opportunities for scientists to create new technologies. The future will bring us even more to look forward to in healthcare technology.
