AI Doesn’t Actually Pose an Existential Threat to Humans, Study Finds

Posted by in categories: existential risks, robotics/AI

Science fiction is riddled with artificial intelligence going rogue and turning on their human creators. HAL-9000. The Matrix. Skynet. GLaDOS. Cylons. Humanity, it seems, has a deep fear of the rebellion of the machine.

With the rise of ever more sophisticated large language models (LLMs), such as Chat GPT, the question of what dangers AI may pose has become even more pertinent.

Neural circuit basis of placebo pain relief

Posted by in categories: biotech/medical, neuroscience

A study in @ Nature identifies using mouse models a neural circuit that may underpin pain relief caused by the placebo effect.


Analgesia from the expectation of pain relief is mediated by rostral anterior cingulate cortex neurons that project to the pontine nucleus.

Juice rerouted to Venus in world’s first lunar-Earth flyby

Posted by in category: space

ESA’s Jupiter Icy Moons Explorer (Juice) has successfully completed a world-first lunar-Earth flyby, using the gravity of Earth to send it Venus-bound, on a shortcut to Jupiter through the inner Solar System.

The closest approach to the Moon was at 23:15 CEST (21:15 UTC) on 19 August, guiding Juice towards a closest approach to Earth just over 24 hours later at 23:56 CEST (21:56 UTC) on 20 August.

Astronomers Discover Record-Breaking Twin Quasars in the Early Universe

Posted by in categories: cosmology, evolution, particle physics

Astronomers have identified the earliest pair of quasars, shining 900 million years post-Big Bang, revealing insights into galaxy mergers and the reionization era of the Universe.

An international team of astronomers, including members from the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI), has discovered the earliest known pair of quasars using the Subaru Telescope and Gemini North telescope, both situated on Maunakea in Hawai’i. These quasars, powered by actively feeding supermassive black holes, emit intense radiation. This significant discovery will provide insights into the early evolution of the Universe.

About 400 million to 1 billion years after the Big Bang, something, possibly a combination of sources, unleashed enough radiation to strip the electrons from most of the hydrogen atoms, completely altering the nature of the Universe. Quasars are one potential source of the radiation that caused this “reionization” of the Universe. When matter falls into the supermassive black hole at the center of a galaxy, the matter heats up and releases radiation in a phenomenon known as a quasar.
