• 27 January – Scientists demonstrate a "Trojan horse" designer-nanoparticle that makes blood cells eat away – from the inside out – portions of atherosclerotic plaque that cause heart attacks[11][12][13] and are the current most common cause of death globally.[14][15]

• 5 February – Scientists develop a CRISPR-Cas12a-based gene editing system that can probe and control several genes at once and can implement logic gating to e.g. detect cancer cells and execute therapeutic immunomodulatory responses.[16][17]

• 6 February – Scientists report that preliminary results from a phase I trial using CRISPR-Cas9 gene editing of T cells in patients with refractory cancer demonstrates that, according to their study, such CRISPR-based therapies can be safe and feasible.[18][19][20][21]

• 4 March – Scientists report that they have developed a way to 3D bioprint graphene oxide with a protein. They demonstrate that this novel bioink can be used to recreate vascular-like structures. This may be used in the development of safer and more efficient drugs.[22][23]

• 4 March – Scientists report to have used CRISPR-Cas9 gene editing inside a human's body for the first time. They aim to restore vision for a patient with inherited Leber congenital amaurosis and state that it may take up to a month to see whether the procedure was successful. In an hour-long surgery study approved by government regulators doctors inject three drops of fluid containing viruses under the patient's retina. In earlier tests in human tissue, mice and monkeys scientists were able to correct half of the cells with the disease-causing mutation, which was more than what is needed to restore vision. Unlike germline editing these DNA modifications aren't inheritable.[24][25][26][27]

• 9 March – Scientists show that CRISPR-Cas12b is a third promising CRISPR editing tool, next to Cas9 and Cas12a, for plant genome engineering.[28][29]

• 14 March – Scientists report in a preprint to have developed a CRISPR-based strategy, called PAC-MAN (Prophylactic Antiviral Crispr in huMAN cells), that can find and destroy viruses in vitro. However, they weren't able to test PAC-MAN on the actual SARS-CoV-2, use a targeting-mechanism that uses only a very limited RNA-region, haven't developed a system to deliver it into human cells and would need a lot of time until another version of it or a potential successor system might pass clinical trials. In the study published as a preprint they write that the CRISPR-Cas13d-based system could be used prophylactically as well as therapeutically and that it could be implemented rapidly to manage new pandemic coronavirus strains – and potentially any virus – as it could be tailored to other RNA-targets quickly, only requiring a small change.[30][31][32][33] The paper was published on 29 April 2020.[34][35]

• 16 March – Researchers report that they have developed a new kind of CRISPR-Cas13d screening platform for effective guide RNA design to target RNA. They used their model to predict optimized Cas13 guide RNAs for all protein-coding RNA-transcripts of the human genome's DNA. Their technology could be used in molecular biology and in medical applications such as for better targeting of virus RNA or human RNA. Targeting human RNA after it's been transcribed from DNA, rather than DNA, would allow for more temporary effects than permanent changes to human genomes. The technology is made available to researchers through an interactive website and free and open source software and is accompanied by a guide on how to create guide RNAs to target the SARS-CoV-2 RNA genome.[36][37]

• 16 March – Scientists present new multiplexed CRISPR technology, called CHyMErA (Cas Hybrid for Multiplexed Editing and Screening Applications), that can be used to analyse which or how genes act together by simultaneously removing multiple genes or gene-fragments using both Cas9 and Cas12a.[38][39]

Their findings may aid the engineering of nanomachines such as for targeted antibiotics.[44][45]

• 20 April – Researchers demonstrate a diffusive memristor fabricated from protein nanowires of the bacterium Geobacter sulfurreducens which functions at substantially lower voltages than previously described ones and may allow the construction of artificial neurons which function at voltages of biological action potentials. The nanowires have a range of advantages over silicon nanowires and the memristors may be used to directly process biosensing signals, for neuromorphic computing and/or direct communication with biological neurons.[46][47][48]

• 27 April – Scientists report to have genetically engineered plants to glow much brighter than previously possible by inserting genes of the bioluminescent mushroom Neonothopanus nambi. The glow is self-sustained, works by converting plants' caffeic acid into luciferin and, unlike for bacterial bioluminescence genes used earlier, has a high light output that is visible to the naked eye.[49][50][51][52][53][54]

• 8 May – Researchers report to have developed artificial chloroplasts – the photosynthetic structures inside plant cells. They combined thylakoids, which are used for photosynthesis, from spinach with a bacterial enzyme and an artificial metabolic module of 16 enzymes, which can convert carbon dioxide more efficiently than plants can alone, into cell-sized droplets. According to the study this demonstrates how natural and synthetic biological modules can be matched for new functional systems.[55][56][57][58]

• 11 May – Researchers report the development of synthetic red blood cells that for the first time have all of the natural cells' known broad natural properties and abilities.

• 17 July – Scientists report that yeast cells of the same genetic material and within the same environment age in two distinct ways, describe a biomolecular mechanism that can determine which process dominates during aging and genetically engineer a novel aging route with substantially extended lifespan.[71][72]

The mice were sent to the International Space Station and could largely maintain their muscle weights – about twice those of wild type due to genetic engineering for targeted deletion of the myostatin gene – under microgravity.[77][78]

• 18 September – Researchers report the development of two active guide RNA-only elements that, according to their study, may enable halting or deleting gene drives introduced into populations in the wild with CRISPR-Cas9 gene editing. The paper's senior author cautions that the two neutralizing systems they demonstrated in cage trials "should not be used with a false sense of security for field-implemented gene drives".[79][80]

• 28 September – Biotechnologists report the genetically engineered refinement and mechanical description of synergistic enzymes – PETase, first discovered in 2016, and MHETase of Ideonella sakaiensis – for faster depolymerization of PET and also of PEF, which may be useful for depollution, recycling and upcycling of mixed plastics along with other approaches.[81][82][83]
