Over-optimization in RL is well-known, but it even occurs when KL(policy || base model) is constrained fairly tightly

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.

Study finds genetics shape caloric restriction’s impact on lifespan

Posted by in categories: genetics, life extension

While caloric restriction (CR) has long been associated with increased lifespan, the study found that its effectiveness is highly influenced by individual genetic factors; some mice on restrictive diets experienced a notable lifespan extension, while others saw minimal gains.


New research on mice suggests that while extreme caloric restriction may extend lifespan, genetic resilience plays a critical role.

Beyond Our Solar System: How Uranus Prepares Us for Exoplanet Discovery

Posted by in categories: futurism, space

“Studying how known benchmarks like Uranus appear in distant imaging can help us have more robust expectations when preparing for these future missions,” said Samantha Hasler. “And that will be critical to our success.”


How can Uranus teach us about exoplanets? This is what a recent study presented at the 56th annual meeting of the American Astronomical Society (AAS) Division for Planetary Sciences (DPS) hopes to address as a team of researchers investigated how gas giants like Uranus can be used to better understand the characteristics of exoplanets. While exoplanets have been discovered using the direct imaging method, no exoplanet has been directly imaged itself. Therefore, this study holds the potential to use gas giant planets within our solar system as analogs for exoplanets throughout the cosmos.

For the study, the researchers analyzed data collected from NASA’s New Horizons spacecraft and the Hubble Space Telescope to study the atmosphere of Uranus in various wavelengths. Both telescopes exhibit different imaging properties, as Hubble is built to obtain up-close images from far away while New Horizons is built to obtain up-close images from close-up. As a result, the images from Hubble revealed far more detail while the images from New Horizons revealed Uranus as a small dot.
