How ‘the strong force’ influences the gravitational wave background

Posted by in categories: cosmology, particle physics

Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe.

Scientists have been looking for signs of these early cosmological , and a team of physicists have now shown that such waves should have a distinct signature due to the behavior of quarks and gluons as the universe cools. Such a finding would have a decisive impact on which models best describe the universe almost immediately after the Big Bang. The study is published in the journal Physical Review Letters.

Scientists first found direct evidence for gravitational waves in 2015 at the LIGO gravitational wave interferometers in the US. These are singular (albeit tiny amplitude) waves from a particular source, such as the merger of two black holes, which wash past Earth. Such waves cause the 4-km perpendicular arms of the interferometers to change length by miniscule (but different) amounts, the difference detected by changes in the resulting interference pattern as travel back and forth in the detector’s arms.

High-speed humanoid feels like a step change in robotics

Posted by in category: robotics/AI

You’ve seen a ton of videos of humanoid robots – but this one feels different. It’s Sanctuary’s Phoenix bot, with “the world’s best robot hands,” working totally autonomously at near-human speeds – much faster than Tesla’s or Figure’s robots.

Canadian company Sanctuary AI has been accelerating its own progress toward general-purpose humanoids, using teleoperation to show Phoenix how to do things, and letting it go away and figure out more in simulation.

Ask Ethan: Will our Universe end the same way it began?

When cosmic inflation came to an end, the hot Big Bang ensued as a result. If our cosmic vacuum state decays, could it all happen again?

A vision of chipped humanity: Brain chip implants like Neuralink raise questions about the future of humanity

Posted by in categories: biotech/medical, cybercrime/malcode, cyborgs, Elon Musk, finance, health, law, robotics/AI, transhumanism

Interestingly enough, although Elon Musk’s Neuralink received a great deal of media attention, early in 2023, Synchron published results from its first-in-human study of four patients with severe paralysis who received its first-generation Stentrode neuroprosthesis implant. The implant allowed participants to create digital switches that controlled daily tasks like sending texts and emails, partaking in online banking, and communicating care needs. The study’s findings were published in a paper in JAMA Neurology in January 2023. Then, before September, the first six US patients had the Synchron BCI implanted. The study’s findings are expected by late 2024.

Let’s return to Upgrade. “One part The Six Million Dollar Man, one part Death Wish revenge fantasy” was how critics described the movie. While Death Wish is a 1974 American vigilante action-thriller movie that is partially based on Brian Garfield’s 1972 novel of the same name, the American sci-fi television series The Six Million Dollar Man from the 1970s, based on Martin Caidin’s 1972 novel Cyborg, could be considered a landmark in the context of human-AI symbiosis, although in fantasy’s domain. Oscar Goldman’s opening line in The Six Million Dollar Man was, “Gentlemen, we can rebuild him. We have the technology. We have the capability to make the world’s first bionic man… Better than he was before. Better—stronger—faster.” The term “cyborg” is a portmanteau of the words “cybernetic” and “organism,” which was coined in 1960 by two scientists, Manfred Clynes and Nathan S Kline.

At the moment, “cyborg” doesn’t seem to be a narrative of a distant future, though. Rather, it’s very much a story of today. We are just inches away from becoming cyborgs, perhaps, thanks to the brain chip implants, although Elon Musk perceives that “we are already a cyborg to some degree,” and he may be right. Cyborgs, however, pose a threat, while the dystopian idea of being ruled by Big Brother also haunts. Around the world, chip implants have already sparked heated discussions on a variety of topics, including privacy, the law, technology, medicine, security, politics, and religion. USA Today published a piece headlined “You will get chipped—eventually” as early as August 2017. And an article published in The Atlantic in September 2018 discussed how (not only brain chips but) microchip implants, in general, are evolving from a tech-geek curiosity to a legitimate health utility and that there may not be as many reasons to say “no.” But numerous concerns about privacy and cybersecurity would keep us haunted. It would be extremely difficult for policymakers to formulate laws pertaining to such sensitive yet quickly developing technology.

‘Bad’ cholesterol gene silenced without altering the DNA sequence

Posted by in categories: biotech/medical, genetics

Because identical twins develop from a single fertilized egg, they have the same genome, the entire set of genetic material found in an organism. So, any differences between them, even in traits with a significant genetic component – say one develops heart disease and the other doesn’t – are due to their environments. This is known as epigenetics.

Genes in DNA are ‘expressed’ when they’re read and transcribed into RNA, which is then translated into proteins. It’s proteins that determine many of a cell’s characteristics and functions. Epigenetic changes can boost or silence the transcription of specific genes, ramping up or inhibiting associated protein production, but they don’t change the genome. These changes, which are reversible, can affect a person for their entire life and mediate a lifelong dialogue between genes and the environment.

Elon Musk sues OpenAI for abandoning original mission for profit

Posted by in categories: Elon Musk, law, robotics/AI

The lawsuit said Altman, along with OpenAI’s co-founder Greg Brockman, originally approached Musk to make an open source, non-profit company that would develop artificial intelligence technology for the “benefit of humanity”

The Microsoft-backed company’s focus on seeking profits breaks that agreement, lawyers for Musk said in the lawsuit.

OpenAI, Microsoft and Musk did not immediately respond to Reuters requests for comment.
