Key Brain Protein Tied to Motivation and Mood Identified

Posted by in category: neuroscience

Summary: A new study has identified a brain protein, vesicular nucleotide transporter (Vnut), as essential for regulating mood and motivation in mice. When Vnut was removed from brain cells called astrocytes, the mice displayed higher anxiety, depression-like behavior, and decreased motivation, especially in females.

This effect was linked to reduced dopamine, a key molecule for motivation and positive mood. These findings suggest Vnut plays a vital role in dopamine regulation, with potential implications for understanding mood disorders.

Why the black hole information paradox still hasn’t been solved

Posted by in categories: cosmology, quantum physics

But you might notice that something is missing: this radiation doesn’t seem to encode, in any way, knowledge of the information that went into the creation of the black hole in the first place. Somewhere along the way, information was destroyed. That’s the key puzzle behind the black hole information paradox. No one seriously disputes the initial setup of the puzzle: that information exists, and that the information (and entropy) does in fact go into the black hole both when it’s first created and also as it grows. What is up for debate, and what in fact is the big question behind the information paradox, is whether that information comes back out again or not.

The way we calculate what comes out of a black hole via Hawking radiation, despite the fact that Hawking radiation has been around for a full half century as of 2024, hasn’t changed all that much over the past 50 years. What we do is assume the curvature of space from general relativity: the fabric of space is curved by the presence of matter and energy, and general relativity tells us exactly by how much.

We then perform our quantum field theory calculations in that curved space, detailing the radiation that comes out as a result. That’s where we learn that the radiation has the temperature, spectrum, entropy, and other properties we know that it possesses, including the fact that it doesn’t appear to encode that initial information when the radiation comes out.

The Creepy Sounds The Earth Made When Its Magnetic Field Flipped Will Haunt Your Dreams

Posted by in category: satellites

Tens of thousands of years ago, the Earth’s magnetic field flipped — and now, scientists have recreated the haunting sound it made during that cataclysmic event.

Using data from the European Space Agency’s three-satellite Swarm mission delving deep into our planet’s magnetic field, Danish and German researchers have managed to map and recreate the sounds of what is known as the Laschamp event, which resulted in Earth’s magnetic field briefly flipping 41,000 years ago.

Scientists Are Developing a Tool That Can ‘See’ Your Consciousness

Posted by in category: robotics/AI

Time, in this view, doesn’t look like a line in which one event causes another. Instead, eight events might be the eight vertices of a cube. Each point may connect with new geometric shapes that arise inside the cube—the vertices of which are also events—or the cube could become a point in a larger geometry. In any case, time is building a geometry like a crystal.

THE TEAM BUILT TWO ARTIFICIAL BRAINS to operate according to these theories so they could observe what happens without the interference of human projections, narratives, and emotions, and compare them with human subjects. An artificial brain doesn’t have an ego or a sense of existential dread, among other things, that might muddy the results. On the other hand, they were limited to a smaller number of primes because the machines don’t have other attributes humans do have.
