Computer Science Proof Unveils Unexpected Form of Entanglement

Posted by in categories: computing, quantum physics, science

Another version of the PCP theorem, not yet proved, specifically deals with the quantum case. Computer scientists suspect that the quantum PCP conjecture is true, and proving it would change our understanding of the complexity of quantum problems. It’s considered arguably the most important open problem in quantum computational complexity theory. But so far, it’s remained unreachable.

Nine years ago, two researchers identified an intermediate goal to help us get there. They came up with a simpler hypothesis, known as the “no low-energy trivial state” (NLTS) conjecture, which would have to be true if the quantum PCP conjecture is true. Proving it wouldn’t necessarily make it any easier to prove the quantum PCP conjecture, but it would resolve some of its most intriguing questions.

Then in June of 2022, in a paper posted to the scientific preprint site arxiv.org, three computer scientists proved the NLTS conjecture. The result has striking implications for computer science and quantum physics.

NOTHING: The Science of Emptiness

Posted by in categories: cosmology, particle physics, science

Why is there something rather than nothing? And what does ‘nothing’ really mean? More than a philosophical musing, understanding nothing may be the key to unlocking deep mysteries of the universe, from dark energy to why particles have mass. Journalist John Hockenberry hosts Nobel laureate Frank Wilczek, esteemed cosmologist John Barrow, and leading physicists Paul Davies and George Ellis as they explore physics, philosophy and the nothing they share.

This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

Does Superdeterminism save Quantum Mechanics? Or does it kill free will and destroy science?

This is a video I have promised you almost two years ago: How does superdeterminism make sense of quantum mechanics? It’s taken me a long time to finish this because I have tried to understand why people dislike the idea that everything is predetermined so much. I hope that in this video I have addressed the biggest misconceptions. I genuinely think that discarding superdeterminism unthinkingly is the major reason that research in the foundations of physics is stuck.

AI visualises every protein known to science

Posted by in categories: robotics/AI, science

DeepMind’s AlphaFold has uncovered the structures of more than 200 million proteins, essentially all of those known to science.

DeepMind’s AI has now catalogued every protein known to science

Posted by in categories: alien life, health, information science, robotics/AI, science

In late 2020, Alphabet’s DeepMind division unveiled its novel protein fold prediction algorithm, AlphaFold, and helped solve a scientific quandary that had stumped researchers for half a century. In the year since its beta release, half a million scientists from around the world have accessed the AI system’s results and cited them in their own studies more than 4,000 times. On Thursday, DeepMind announced that it is increasing that access even further by radically expanding its publicly-available AlphaFold Protein Structure Database (AlphaFoldDB) — from 1 million entries to 200 million entries.

Alphabet partnered with EMBL’s European Bioinformatics Institute (EMBL-EBI) for this undertaking, which covers proteins from across the kingdoms of life — animal, plant, fungi, bacteria and others. The results can be viewed on the UniProt, Ensembl, and OpenTargets websites or downloaded individually via GitHub, “for the human proteome and for the proteomes of 47 other key organisms important in research and global health,” per the AlphaFold website.

“AlphaFold is the singular and momentous advance in life science that demonstrates the power of AI,” Eric Topol, Founder and Director of the Scripps Research Translational Institute, siad in a press statement Thursday. “Determining the 3D structure of a protein used to take many months or years, it now takes seconds. AlphaFold has already accelerated and enabled massive discoveries, including cracking the structure of the nuclear pore complex. And with this new addition of structures illuminating nearly the entire protein universe, we can expect more biological mysteries to be solved each day.”

Once-ignored Indigenous knowledge of nature now shaping science

Posted by in categories: climatology, science

Traditional ecological knowledge has long been dismissed by Western culture as stories or legends, rather than real science. But there’s new interest in tapping into the wisdom about plants, trees, wildlife and climate that Native American people have collected over time.

The Webb Telescope’s Latest Science Images Show The ‘Phantom Galaxy’ And More In Breathtaking Depth And Detail

Posted by in categories: science, space

Just days after the first formal release of its first show-off images scientists using the new James Webb Space Telescope (JWST) have posted some stunning new images of two spiral galaxies.

Posted on Flickr by Judy Schmidt working on the PHANGS Survey, the stunning image, above, shows the spectacular “Phantom Galaxy” (also called M74 and NGC 628), with others (scroll down) showing another spiral galaxy called NGC 7496.

The incredible new images are testament to Webb’s skill at seeing in infrared and thus seeing through the gas and dust that obscures a lot of what is going on in some of the most arresting objects in the night sky.
