Riffing off Elon Musk’s goal of sending humans to Mars by 2024, and NASA’s plans to send astronauts there after they visit the Moon again, Rice University evolutionary biologist Scott Solomon envisions “mutations cascading through the gene pool”: After about two generations, he thinks their bones will strengthen, they’ll need glasses for nearsightedness, their immune systems will be null, pregnancy and childbirth will be significantly more perilous, and the exposure to radiation—more than 5,000 times the amount we’re exposed to on Earth during a normal lifetime, Solomon says—could lead to an influx of cancer.Natalie Coleman, “Evolutionary Biologist: Mars Colonists Will Mutate Really Fast” at Futurism As a result, he thinks Martians should stop having kids with Earthlings.

Let’s read the Nature abstract: Nature (2019) Article | Published: 15 May 2019 Total synthesis of Escherichia coli with a recoded genome Julius Fredens, Kaihang Wang, Daniel de la Torre, Louise F. H. Funke, Wesley E. Robertson, Yonka Christova, Tiongsun Chia, Wolfgang H. Schmied, Daniel L. Dunkelmann, Václav Beránek, Chayasith Uttamapinant, Andres Gonzalez Llamazares, Thomas S. Elliott & Jason W. Chin AbstractNature uses 64 codons to encode the synthesis of proteins from the genome, and chooses 1 sense codon—out of up to 6 synonyms—to encode each amino acid. Synonymous codon choice has diverse and important roles, and many synonymous substitutions are detrimental. Here we demonstrate that the number of codons used to encode the canonical amino acids can be reduced, Read More ›

Some dates are being discussed in a May 18th 2019 Phys-dot-org article: “The Moon is the proving ground for our eventual mission to Mars,” NASA administrator Jim Bridenstine said at a conference this week. “The Moon is our path to get to Mars in the fastest, safest way possible. That’s why we go to the Moon.” According to Robert Howard, who heads up the lab developing future space habitats at the legendary Johnson Space Center in Houston, the hurdles aren’t so much technical or scientific as much as a question of budget and political will. “A lot of people want us to have an Apollo moment, and have a president stand up like Kennedy and say, we’ve got to do Read More ›
