Glass nanoparticles trapped by lasers in extreme vacuum are considered a promising platform for exploring the limits of the quantum world. Since the advent of quantum theory, the question at which sizes an object starts being described by the laws of quantum physics rather than the rules of classical physics has remained unanswered.

A team formed by Lukas Novotny (ETH Zurich), Markus Aspelmeyer (University of Vienna), Oriol Romero-Isart (University of Innsbruck), and Romain Quidant (Zurich) is attempting to answer precisely this question within the ERC-Synergy project Q-Xtreme. A crucial step on the way to this goal is to reduce the energy stored in the motion of the nanoparticle as much as possible, i.e. to cool the particle down to the so-called quantum ground-state.

From burgers to sausages and steak tips to chicken nuggets, there’s no shortage of plant-based “meat” products on grocery store shelves and in restaurants these days. Companies like Beyond Meat and Impossible Foods have done an impressive job diversifying their offerings, with almost any processed meat you can think of now on their lists (even beef jerky and popcorn chicken). But a key cut of meat is still missing from these big names’ menus: a good old-fashioned filet, just like the cows make ‘em.

I served the steak with quinoa and sauteed veggies, and after a few bites, I couldn’t deny it was both tasty and had a pleasant texture. Did it taste or feel like a real steak? Not really. The real meat it most reminded me of was rib meat, the kind that easily pulls off the bone when the ribs have been slow-cooked; soft and tender, but not dried out. The plant-based steak had a distinctly fatty-like mouthfeel without the excessive oiliness you sometimes get from animal fat.

The most famous one is the cell phone itself: Captain Kirk’s communicator inspired the folks at Motorola to make the first handheld mobile device in 1973. Star Trek: The Original Series (popularly called TOS) from the 1960s also inspired video conferencing. But things started to amp up when, in 1987, Star Trek: The Next Generation (aka TNG) hit the floors, with Sir Patrick Stewart in the lead. It became one of the most syndicated shows on television—which is how I discovered it in mid-90s India on the Star network. It fundamentally impacted my life, inspiring me to become the technology writer I am today.

But more than me, this show heralded more technological concepts that are becoming increasingly real. The LCARS computer on the Galaxy-Class USS Enterprise D is basically the foundation of what Google is today. Google’s former head of search, Amit Singhal, often said that the company is “trying to build the Star Trek computer”.

Regeneration, Resuscitation & Biothreat Countermeasures — Commander Dr. Jean-Paul Chretien, MD, Ph.D., Program Manager, Biological Technology Office, DARPA

Commander Dr. Jean-Paul Chretien, MD, Ph.D. (https://www.darpa.mil/staff/cdr-jean-paul-chretien) is a Program Manager in the Biological Technology Office at DARPA, where his research interests include disease and injury prevention, operational medicine, and biothreat countermeasures. He is also responsible for running the DARPA Triage Challenge (https://triagechallenge.darpa.mil/).

Prior to coming to DARPA, CDR Dr. Chretien led the Pandemic Warning Team at the Defense Intelligence Agency’s National Center for Medical Intelligence, and as a naval medical officer, his previous assignments include senior policy advisor for biodefense in the White House Office of Science and Technology Policy; team lead for Innovation & Evaluation at the Armed Forces Health Surveillance Branch; and director of force health protection for U.S. and NATO forces in southwestern Afghanistan.

A 1960s nuclear research lab in the North of England will host a new quantum computing facility under plans drawn up by a Silicon Valley technology company.

PsiQuantum is to set up a research hub at the Daresbury Laboratory in Cheshire, using the facility’s state of the art cooling systems to develop its technology.

PsiQuantum, which is backed by BlackRock, Microsoft and Baillie Gifford, was set up by professors at the University of Bristol and Imperial College London but its founders moved to Silicon Valley in 2016 under advice from investors.

Among “the jobs once done by God [that] can be done by natural entities” there is life after death. Dawkins “frequently affirms that there is no life after death”, but Steinhart shows that this is inconsistent with Dawkins’ own convictions. Dawkins “should have argued that false religious theories of life after death can be replaced with more plausible scientific theories of life after death” [**].

Steinhart describes two plausible scientific theories of life after death: promotion to the higher level of reality of the simulators, and revisions of entire lives in new universes, each better than the previous life and universe. Worth noting, promotion could preserve memories and implement “the ancient idea of the resurrection of the body.” These theories of life after death are only sketched in this book, see Steinhart’s previous book “Your Digital Afterlives: Computational Theories of Life after Death” for more. See also my review of “Your Digital Afterlives” in “Tales of the Turing Church” (Chapter 12).

In summary, Steinhart builds a thorough and philosophically consistent spiritual naturalism, inspired by Dawkins, which offers the main mental benefits of religion. I like (actually I love) philosophy, but I try to keep mine as simple and working-class as possible, because many people don’t have the patience (or the time) for too much philosophical sophistication. I think the two approaches are complementary. So I use the term “religion” for the spiritual naturalism of Dawkins and Steinhart, and I use the simple term “God” now and then.
