Apr 8, 2025 · News and articles about advances in genetic sequencing, genetics and how DNA (deoxyribonucleic acid) might be used in the future. ... A DNA sequence is a specific lineup of chemical base pairs ...

Feb 27, 2025 · In some, the RNA-binding region is adjacent to a DNA-cutting part of the protein. Others appear to bind to other proteins, which suggests they might help direct those proteins to DNA targets. Zhang and his team experimented with dozens of Tas proteins, demonstrating that some can be programmed to make targeted cuts to DNA in human cells.

Feb 13, 2025 · DNA and RNA epigenetics, once thought to be separate, have now been found to work together to fine-tune gene expression. ... News. By Jennifer Zieba published 13 February 2025

Jan 30, 2024 · Using a virus-like delivery particle made from DNA, researchers from MIT and the Ragon Institute of MGH, MIT, and Harvard have created a vaccine that can induce a strong antibody response against SARS-CoV-2. The vaccine, which has been tested in mice, consists of a DNA scaffold that carries many copies of a viral antigen.

Jan 31, 2025 · Inside the cell nucleus, DNA and proteins form a complex called chromatin, which has several levels of organization, allowing cells to cram 2 meters of DNA into a nucleus that is only one-hundredth of a millimeter in diameter. Long strands of DNA wind around proteins called histones, giving rise to a structure somewhat like beads on a string.

Jun 13, 2024 · Capturing DNA. DNA, a very stable molecule, is well-suited for storing massive amounts of information, including digital data. Digital storage systems encode text, photos, and other kind of information as a series of 0s and 1s. This same information can be encoded in DNA using the four nucleotides that make up the genetic code: A, T, G, and C.

Jul 14, 2021 · The extent of these DNA double-strand breaks (DSBs) in multiple key brain regions is surprising and concerning, says study senior author Li-Huei Tsai, Picower Professor of Neuroscience at MIT and director of The Picower Institute for Learning and Memory, because while the breaks are routinely repaired, that process may become more flawed and ...

5 days ago · The Old Crow mammoth's DNA was in the oldest group of samples in the analysis, described as "deep-time DNA," but it wasn't the oldest. The oldest DNA, from Russia, was around 1.3 million years old.

Apr 3, 2025 · A protein from tiny tardigrades may help cancer patients tolerate radiation therapy. When scientists stimulated cells to produce a protein that helps “water bears” survive extreme environments, the tissue showed much less DNA damage after radiation treatment.
