My now decade-old book The Forever Fix: Gene Therapy and the Boy who Saved It , told the stories of children who had received one-time deliveries of working copies of genes, to compensate for their mutations. This DNA Science post from 2018 traces the history of the efforts. DEB has been a candidate for a gene therapy since 2002.
billion bases of DNA which, if unfurled, would extend for more than 100 meters—taller than the Statue of Liberty. billion bases of DNA, the human genome measures just 2 meters in length when stretched end-to-end. Credit: Oriane Hidalgo Per the book Cell Biology by the Numbers , each base pair of DNA occupies 1 nm 3 of space.
But the book has a glitch in a genetic explanation. He had the top book, film, and TV series within the same week – twice. See How Michael Crichton’s Widow Sherri Ushered in a Renaissance of His Work With New Book ‘Eruption’ in Variety.) ” I can’t wait for the film. He was too busy creating.
The title Ordinary Soil alone would have drawn me to this book, for years ago, a dear botanist friend admonished me for using “dirt” and “soil” interchangeably, although dictionaries do so. Although the book is based on this very distinction, towards the end, “dirt” dominates.
Over time, the mineralized microbes of tooth tartar come to comprise a mouthful of tiny fossils, including snippets of degraded bacterial DNA. ” But long DNA molecules fray as they’re copied as bacteria reproduce, from ancient times leaving pieces too small to match entries in DNA databases from modern species.
In the final chapter of my 2012 book The Forever Fix: Gene Therapy and the Boy Who Saved It , I predicted that the technology would soon expand well beyond the rare disease world. million DNA bases. The DMD gene therapy delivers a shortened version of the dystrophin gene, just 4,558 DNA bases. I was overoptimistic.
” CRISPRs are short DNA sequences, peppered with repeats, that latch onto DNA-cutting enzymes, commandeering and directing them to snip certain parts of a chromosome. Unlike gene therapy as originally-envisioned since the 1950s, which adds a functioning copy of a gene, CRISPR can add, remove, or replace a DNA sequence.
They’ve just finished sequencing the patient’s genome, but they don’t have “DNA sorting” software. And that’s how I learned that there are published books that contain entire chromosome sequences. A real book that contains the full sequence of human chromosome 21. From Ling B et al.

Yeast die for two reasons: Either their nucleolus (where the DNA is kept) degrades and dies, or their mitochondria whimpers out and they stop making energy. The vaccine printer can make lots of different types of vaccines, including protein, DNA, and mRNA ones, but I’m sure this is all quite expensive right now. From Zhang et al.

As genetics morphed into genomics, artificial intelligence stepped in, layering the combinatorial information of comparative genomics onto DNA sequences. Train an algorithm on the DNA sequences of a known disease-causing gene, then search for identical or highly similar sequences in cells from other individuals to assist diagnosis.
“The recombinant DNA breakthrough has provided us with a new and powerful approach to the questions that have intrigued and plagued man for centuries. The central dogma is often depicted as DNA→RNA→protein, but it’s much more: A biophysical marvel inside the smallest of vessels. Biology is a Burrito.
Short DNA strands were discovered that can specifically and tightly bind to zinc and cadmium ions. Perhaps there is now a way to use DNA to extract metals: You could fuse the DNA strands to an antibody, coat them onto electronics, and then use a column to isolate the DNA:metal compounds? coli DNA using a Retro-Cascorder.
This week: A way to measure a transgene’s expression in the brain using ultrasound, a DNA sequencing method that uses 1000x less reagents, and base editors get even smaller. An engineered version of this protein can convert DNA bases with efficiencies up to 92%. so this Digest will be published more irregularly.

Neural networks easily spot patterns across vast libraries of books and internet articles to learn — or at least imitate — the inner workings of language. The same model can also generate brand-new DNA sequences at the scale of yeast chromosomes or small bacterial genomes. Like ChatGPT, Evo 2 is a large language model.
Influenza incidence and severity are increasing , against a backdrop of novel drifts (small genetic changes) and shifts (larger changes) to the virus, all against a backdrop of novel infection pathways, such as birds to cows to people. The mRNA in COVID vaccines tells cells to produce the virus’s spike protein.
A few weeks ago, I noticed a surprising metric when posting my weekly DNA Science blog – at year’s end, I’d hit #500! The Birth of DNA Science When St. Martin’s Press was about to publish my book about gene therapy in 2012, my agent urged me to start blogging. We renamed it DNA Science.
That tragedy lies behind the riveting medical detective story of “The Dressmaker’s Mirror,” an excellent new book by geneticist Susan Weiss Liebman, research professor at the University of Nevada, Reno. Dr. McNally checked Diane’s DNA for new mutations as they were discovered. Liebman’s sister Diane.
Many students are taught that the Central Dogma is simply “DNA → RNA → protein.” In 1956, Crick was working on a lecture that would bring together what was then known about the “flow of information” between DNA, RNA, and protein in cells.
For example, cloning DNA molecules and inserting them into cells — a process required for basically all experiments in molecular biology — takes up to a week of work. Perhaps you’ve seen this chart before, which shows the falling costs of DNA sequencing over the last two decades. If we could get E.
The book has a conversational tone, an easy read even for the science-shy. Yet the book is also global in scope. A virus that directly attacks the immune response presents a special challenge. The 1918 virus was H1N1, and the one behind a million deaths in 1957, H2N2. Ebola virus fever is horrific.
