The new tool has the capacity to undertake strand-specific gene editing without any cuts.
Chinese researchers claim to have created a new gene-editing technique called CyDENT that is more effective than Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) technology.
This is according to a report by the South China Morning Post (SCMP) published on Saturday.
The cutting-edge gene-editing technique CRISPR enables precise DNA changes within an organism’s genome. Its development in the past few years has significantly advanced genetic engineering and biotechnology.
The organism fared better at converting organic waste to electricity than even some famous and exotic electricity producing microbes.
Scientists at the Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland have successfully engineered E.coli.
Escherichia coli, commonly known as E.coli, is a rod-shaped bacterium commonly found in the lower gut of organisms. However, it has become a favorite of microbial researchers worldwide for the ease with which its genetic structure can be manipulated. It has, therefore, become an indispensable part of research and industrial projects.
For years, researchers have tried various ways to coax quantum bits—or qubits, the basic building blocks of quantum computers—to remain in their quantum state for ever-longer times, a key step in creating devices like quantum sensors, gyroscopes, and memories.
A team of physicists from MIT have taken an important step forward in that quest, and to do it, they borrowed a concept from an unlikely source—noise-cancelling headphones.
Led by Ju Li, the Battelle Energy Alliance Professor in Nuclear Engineering and professor of materials science and engineering, and Paola Cappellaro, the Ford Professor of Engineering in the Department of Nuclear Science and Engineering and Research Laboratory of Electronics, and a professor of physics, the team described a method to achieve a 20-fold increase in the coherence times for nuclear-spin qubits.

More remarkably, the advent of artificial intelligence (AI) and machine learning-based computers in the next century may alter how we relate to ourselves.
The digital ecosystem’s networked computer components, which are made possible by machine learning and artificial intelligence, will have a significant impact on practically every sector of the economy. These integrated AI and computing capabilities could pave the way for new frontiers in fields as diverse as genetic engineering, augmented reality, robotics, renewable energy, big data, and more.
Three important verticals in this digital transformation are already being impacted by AI: 1) Healthcare, 2) Cybersecurity, and 3) Communications.
A molecular assembler, as defined by K. Eric Drexler, is a “proposed device able to guide chemical reactions by positioning reactive molecules with atomic precision”. A molecular assembler is a kind of molecular machine. Some biological molecules such as ribosomes fit this definition. This is because they receive instructions from messenger RNA and then assemble specific sequences of amino acids to construct protein molecules. However, the term “molecular assembler” usually refers to theoretical human-made devices.
Beginning in 2007, the British Engineering and Physical Sciences Research Council has funded development of ribosome-like molecular assemblers. Clearly, molecular assemblers are possible in this limited sense. A technology roadmap project, led by the Battelle Memorial Institute and hosted by several U.S. National Laboratories has explored a range of atomically precise fabrication technologies, including both early-generation and longer-term prospects for programmable molecular assembly; the report was released in December, 2007. In 2008 the Engineering and Physical Sciences Research Council provided funding of 1.5 million pounds over six years for research working towards mechanized mechanosynthesis, in partnership with the Institute for Molecular Manufacturing, amongst others. Likewise, the term “molecular assembler” has been used in science fiction and popular culture to refer to a wide range of fantastic atom-manipulating nanomachines, many of which may be physically impossible in reality. Much of the controversy regarding “molecular assemblers” results from the confusion in the use of the name for both technical concepts and popular fantasies. In 1992, Drexler introduced the related but better-understood term “molecular manufacturing”, which he defined as the programmed “chemical synthesis of complex structures by mechanically positioning reactive molecules, not by manipulating individual atoms”.This article mostly discusses “molecular assemblers” in the popular sense. These include hypothetical machines that manipulate individual atoms and machines with organism-like self-replicating abilities, mobility, ability to consume food, and so forth. These are quite different from devices that merely (as defined above) “guide chemical reactions by positioning reactive molecules with atomic precision”. Because synthetic molecular assemblers have never been constructed and because of the confusion regarding the meaning of the term, there has been much controversy as to whether “molecular assemblers” are possible or simply science fiction. Confusion and controversy also stem from their classification as nanotechnology, which is an active area of laboratory research which has already been applied to the production of real products; however, there had been, until recently, no research efforts into the actual construction of “molecular assemblers”. Nonetheless, a 2013 paper by David Leigh’s group, published in the journal Science, details a new method of synthesizing a peptide in a sequence-specific manner by using an artificial molecular machine that is guided by a molecular strand. This functions in the same way as a ribosome building proteins by assembling amino acids according to a messenger RNA blueprint. The structure of the machine is based on a rotaxane, which is a molecular ring sliding along a molecular axle. The ring carries a thiolate group which removes amino acids in sequence from the axle, transferring them to a peptide assembly site. In 2018, the same group published a more advanced version of this concept in which the molecular ring shuttles along a polymeric track to assemble an oligopeptide that can fold into a α-helix that can perform the enantioselective epoxidation of a chalcone derivative (in a way reminiscent to the ribosome assembling an enzyme). In another paper published in Science in March 2015, chemists at the University of Illinois report a platform that automates the synthesis of 14 classes of small molecules, with thousands of compatible building blocks. In 2017 David Leigh’s group reported a molecular robot that could be programmed to construct any one of four different stereoisomers of a molecular product by using a nanomechanical robotic arm to move a molecular substrate between different reactive sites of an artificial molecular machine. An accompanying News and Views article, titled ‘A molecular assembler’, outlined the operation of the molecular robot as effectively a prototypical molecular assembler.

Throughout Gray’s life before she got the treatment, the deformed, sickle-shaped red blood cells caused by the genetic disorder would regularly incapacitate her with intense, unpredictable attacks of pain. Those crises would send Gray rushing to the hospital for pain medication and blood transfusions. She could barely get out of bed many days; when she became a mom, she struggled to care for her four children and couldn’t finish school or keep a job.
But then she received the treatment on July 2, 2019. Doctors removed some of her bone marrow cells, genetically modified them with CRISPR and infused billions of the modified cells back into her body. The genetic modification was designed to make the cells produce fetal hemoglobin, in the hopes the cells would compensate for the defective hemoglobin that causes the disease.
A Mississippi woman’s life has been transformed by a treatment for sickle cell disease with the gene-editing technique CRISPR. All her symptoms from a disease once thought incurable have disappeared.
