Will scientists ever be able to create ‘better’ DNA in the lab than evolution did in nature?

In a milestone for synthetic biology, colonies of E. coli thrive with DNA constructed from scratch by humans, not nature.

Creationism is “an absolutely horrible hypothesis,” says the author of a new study of the statistical probability of a universal common ancestor.
A newly-designed atomic clock uses entangled atoms to keep time even more precisely than its state-of-the-art counterparts. The design could help scientists detect dark matter and study gravity’s effect on time.
Such primordial black holes (PBHs) could account for all or part of dark matter, be responsible for some of the observed gravitational waves signals, and seed supermassive black holes found in the center of our Galaxy and other galaxies. They could also play a role in the synthesis of heavy elements when they collide with neutron stars and destroy them, releasing neutron-rich material. In particular, there is an exciting possibility that the mysterious dark matter, which accounts for most of the matter in the universe, is composed of primordial black holes. The 2020 Nobel Prize in physics was awarded to a theorist, Roger Penrose, and two astronomers, Reinhard Genzel and Andrea Ghez, for their discoveries that confirmed the existence of black holes. Since black holes are known to exist in nature, they make a very appealing candidate for dark matter.
The recent progress in fundamental theory, astrophysics, and astronomical observations in search of PBHs has been made by an international team of particle physicists, cosmologists and astronomers, including Kavli IPMU members Alexander Kusenko, Misao Sasaki, Sunao Sugiyama, Masahiro Takada and Volodymyr Takhistov.
To learn more about primordial black holes, the research team looked at the early universe for clues. The early universe was so dense that any positive density fluctuation of more than 50 percent would create a black hole. However, cosmological perturbations that seeded galaxies are known to be much smaller. Nevertheless, a number of processes in the early universe could have created the right conditions for the black holes to form.
By capsule, helicopter, boat, plane, and car, space station science experiments are about to make a first of a kind journey back to researchers on Earth.
Do we have to age?

Once, at a friend’s wedding, he left a group of guests mildly incensed for suggesting that near-future humans might live well into their 100s. A similar thing happens at dinner parties, where the responses are more polite but no less sceptical. Eventually, he says, “I think we are very likely to have a drug that treats ageing in the next 10 years.” Steele believes we will be hopelessly unlucky if scientists don’t make a breakthrough within that time, given how many human trials are in progress or upcoming. And although these breakthroughs won’t result in treatments that extend our lives by 100 years, they will give us enough extra time to ensure we’re alive for subsequent breakthroughs, subsequent treatments, subsequent additions in lifespan and so on.
The biologist Andrew Steele thinks ageing is a disease that can be treated. But if we had a cure for getting old, what would that mean for us?
