BLUE STAR NEWS Scientists Changed a Lifeform’s Fundamental Code. It shouldn't have survived, but it did. PART 1 A team of genetic engineers has successfully stripped away seven of the fundamental biological instructions used by every known living organism on Earth. In doing so, they created a synthetic lifeform that operates on a completely compressed version of life’s operating system, and against all scientific expectations, it survived. The breakthrough, led by researchers at the Medical Research Council's Laboratory of Molecular Biology in Cambridge, resulted in the creation of Syn57, a fully synthetic strain of Escherichia coli bacteria. To understand what scientists changed, it helps to understand how DNA works. Every living thing, from a single-celled microbe to a human being, uses the exact same genetic dictionary. DNA is read in three-letter "words" called codons. There are 64 possible codons, but nature only uses them to build 20 amino acids (the building blocks of proteins) and a few punctuation marks, like "stop" signs. Because there are 64 words but only 20 amino acids, life has massive amounts of redundancy. For example, the amino acid serine can be spelled six different ways. In 1968, legendary co-discoverer of DNA Francis Crick proposed that this layout was a "frozen accident," a random, inefficient system that got locked into early evolutionary history simply because it worked well enough. Scientists wanted to see if life could tolerate a deeper, cleaner rewrite. They designed a computer blueprint to entirely eliminate seven specific codons from the bacterium's genome:
Four of the six codons for serine. Two of the four codons for alanine. One of the three "stop" signals. This required making more than 101,000 precise modifications across the organism's four-million-letter genome. Rather than traditional gene editing, which cuts and pastes existing DNA, the team chemically synthesized the entire altered genome from scratch in a laboratory and stitched it together piece by piece.

Assembling a functioning genome with this many changes was considered nearly impossible. During the construction phase, the project hit multiple dead ends. When you change that many genetic "letters" simultaneously, it often alters overlapping genes or disrupts how the cell physical
