There have been some who have complained about the seeming lack of acceleration or slower than some have expected development of societal technology.
Richard Jones talks about lack of specific progress to diamondoid molecular nanotechnology or the appearance that we might not be on track to a technological singularity.

Antibiotics have emerged as potentially lifespan-enhancing drugs, according to the results of new research carried out in the UK.
Genetic experiments that eliminate “senescent” cells – older cells, which lose the ability to divide – have already been proven to alleviate age-related dysfunction in model organisms.
Now, scientists have shown for the first time that an FDA-approved antibiotic – Azithromycin – can effectively target and eliminate senescent cells in culture.

Elon Musk has Tweeted some of the details of the breakthrough changes to the SpaceX Super Heavy Starship.
The overall shape of the SpaceX Super Heavy Starship are about the same. However, there are fundamental materials change to airframe, tanks and heatshield.
@elonmusk Elon, how long until we can have more tech details about the bfs design changes? Some of us rocket nerds are dying to know anything! Thanks!

Ultracold quantum mix
Posted in particle physics, quantum physics
The experimental investigation of ultracold quantum matter makes it possible to study quantum mechanical phenomena that are otherwise inaccessible. A team led by the Innsbruck physicist Francesca Ferlaino has now mixed quantum gases of two strongly magnetic elements, erbium and dysprosium, and created a dipolar quantum mixture.
A few years ago, it seemed unfeasible to extend the techniques of atom manipulation and deep cooling in the ultracold regime to many-valence-electron atomic species. The reason is the increasing complexity in the atomic spectrum and the unknown scattering properties. However, a team of researchers, led by Ben Lev at Stanford University and an Austrian team directed by Francesca Ferlaino at the University of Innsbruck demonstrated quantum degeneracy of rare-earth species. Ferlaino’s group focused the research on erbium and developed a powerful, yet surprisingly simple approach to produce a Bose-Einstein condensate.
“We have shown how the complexity of atomic physics can open up new possibilities,” says Ferlaino. Magnetic species are an ideal platform to create dipolar quantum matter, in which particles interact with each other via a long-range and orientation dependent interaction as little quantum magnets.

A remarkable study from researchers at the Salk Institute has uncovered a profound new insight into how our circadian rhythms are regulated through light-sensing mechanisms within our eyes. The research could lead to new ways to combat insomnia and help reset the internal clocks of people with disrupted circadian rhythms.
