“There is only one interpretation of quantum mechanics” | David Deutsch FULL INTERVIEW

David Deutsch, known as the ‘father of quantum computing’, explains how accepting the reality of quantum mechanics means accepting the multiverse.

How are the branches of a multiverse different from each other?

The many-worlds interpretation of quantum mechanics says that all possible outcomes of quantum measurements are physically realised in different worlds. These many worlds have proved extremely contentious, with critics arguing that they are mere fantasy. In this exclusive interview, leading physicist David Deutsch explains the philosophy behind the many-worlds interpretation and argues that not only is it the best interpretation of quantum mechanics – it is the only interpretation.

David Deutsch is a theoretical physicist best known as the founding father of quantum computation and as a key figure and advocate for the many-worlds interpretation of quantum mechanics. Deutsch is a Visiting Professor of physics at the Centre for Quantum Computation and the Clarendon Laboratory, Oxford University. Interviewed by Charlie Barnett, Senior Producer at the IAI.

“Uncharted Waters”: Large Hadron Collider Begins Colliding Oxygen For The First Time

For example, when studying heavier ion collisions and xenon-xenon collisions, scientists at ATLAS saw “jet quenching”, as high-energy particles lose energy as they negotiate the quark-gluon plasma. Jet quenching was not seen in proton-lead collisions, which formed a smaller quark-gluon plasma system.

“Theory predicts we should see the onset of jet quenching in oxygen–oxygen collisions,” Longo added. “If we observe even modest suppression, it could pin down the critical system size at which jet quenching begins.”

Also of interest in these studies is the “collective flow” seen in the collective motion of particles that emerge from the quark-gluon plasma. Studying oxygen collisions could help tell us more about this collective behavior, whilst also telling us about the geometrical structure of oxygen nuclei. Meanwhile, colliding neon could tell us about its structure too, thought to be roughly in the shape of a bowling pin. The shape itself could have an impact on the formation of quark-gluon plasma.

Inside baseball: The founder’s guide to funding health and science organizations

Investors sign hundreds of term sheets over their careers. Founders only do so a handful of times. When you’re raising money to bring your idea to life, there are a myriad of decisions you need to make — what sources of funding to pursue, how to structure your company, what timeline you should work towards.

OpenAI co-founder Sutskever sets up new AI company devoted to ‘safe superintelligence’

(AP) — Ilya Sutskever, one of the founders of OpenAI who was involved in a failed effort to push out CEO Sam Altman, said he’s starting a safety-focused artificial intelligence company.

Sutskever, a respected AI researcher who left the ChatGPT maker last month, said in a social media post Wednesday that he’s created Safe Superintelligence Inc. with two co-founders. The company’s only goal and focus is safely developing “superintelligence” — a reference to AI systems that are smarter than humans.

The company vowed not to be distracted by “management overhead or product cycles,” and under its business model, work on safety and security would be “insulated from short-term commercial pressures,” Sutskever and his co-founders Daniel Gross and Daniel Levy said in a prepared statement.

NASA announces Voyager 1’s stunning new discovery at the outer limits of our solar system

Voyager 1, launched in 1977, has been journeying through space for over four decades, now more than 14.9 billion miles away from Earth. Recently, this legendary probe made headlines once again by crossing an invisible border that separates our solar system from the vast expanse of interstellar space. What it discovered there has left scientists astounded—a “wall of fire” where temperatures soar to an unimaginable 54,000 degrees Fahrenheit.

If you have an old remote control at home, you’re sitting on a treasure: here’s how and why to reuse it

Since its launch, Voyager 1 has sent back breathtaking images of Jupiter, Saturn, and their moons. But its most daring journey began when it left the familiar territory of the planets behind and headed toward what is known as the heliopause. This is the vast boundary where the sun’s influence fades and the realm of interstellar space begins.

Research teases apart competing transcription organization models

Scientists at St. Jude Children’s Research Hospital have reconciled two closely related but contentious mechanisms underlying transcription, the process of converting genetic information in DNA into messenger RNA. Phase separation has been proposed as a driving force in transcription due to its ability to selectively concentrate proteins and DNA in discrete droplets.

Sphingosine simultaneously inhibits nuclear import and activates PP2A by binding importins and PPP2R1A

Mechanism of sphingosine mediated tumor suppression.

Both sphingosine and ceramide suppress tumor growth, but the molecular details of this regulation are currently unclear.

Sphingosine-like compounds bind to their target proteins and trigger structural changes that activate PP2A (the protein phosphatase 2A (PP2A) scaffold (PPP2R1A)) and inhibit the importins (KPNB1, TNPO1, IPO7, IPO5).

Together, these actions disable proteins that drive cancer initiation and progression (e.g., YAP, JUN, MYC, the androgen receptor, hnRNPA1, NF-κB, and ribosomal proteins) by triggering their proteasomal degradation and/or inhibiting their nuclear import.

Together, these pathways elicit more robust effects than activating PP2A or inhibiting importins individually.

The effect of endogenous sphingosine on these oncoproteins is limited by its metabolic conversion into ceramide or sphingosine-1-phosphate. https://sciencemission.com/Sphingosine-simultaneously-inhibits
