The Day We Give Birth to AGI — Stuart Russell’s Warning About AI

Posted by in categories: futurism, robotics/AI

Stuart Russell warns about the dangers involved in the creation of artificial intelligence. Particularly, artificial general intelligence or AGI.
The idea of an artificial intelligence that might one day surpass human intelligence has been captivating and terrifying us for decades now. The possibility of what it would be like if we had the ability to create a machine that could think like a human, or even surpass us in cognitive abilities is something that many envision. But, as with many novel technologies, there are a few problems with building an AGI. But what if we succeed? What would happen should our quest to create artificial intelligence bear fruit? How do we retain power over entities that are more intelligent than us? The answer, of course, is that nobody knows for sure. But there are some logical conclusions we can draw from examining the nature of intelligence and what kind of entities might be capable of it.

Stuart Russell is a Professor of Computer Science at the University of California at Berkeley, holder of the Smith-Zadeh Chair in Engineering, and Director of the Center for Human-Compatible AI. He outlines the definition of AI, the risks and benefits it poses for the future. According to him, the idea of an AGI is the most important problem to intellectually to work on.

The shape of the Milky Way

Posted by in categories: innovation, space

To understand the nature of our galaxy, astronomers had to look to distant island universes.


Turn your eyes toward the night sky and you will see a bright, hazy band of light cutting across the sky.

For millennia, observers speculated about the Milky Way’s true nature. The Greeks said the streak of haze in the sky was milk spurting from the breast of the goddess, Hera, Egyptians thought it was cows’ milk, and some Aboriginal Australians thought it was a river flowing through the sky.

ATLAS strengthens its search for supersymmetry

Posted by in categories: cosmology, particle physics, robotics/AI

Where is all the new physics? In the decade since the Higgs boson’s discovery, there have been no statistically significant hints of new particles in data from the Large Hadron Collider (LHC). Could they be sneaking past the standard searches? At the recent Rencontres de Moriond conference, the ATLAS collaboration at the LHC presented several results of novel types of searches for particles predicted by supersymmetry.

Supersymmetry, or SUSY for short, is a promising theory that gives each elementary particle a “superpartner”, thus solving several problems in the current Standard Model of particle physics and even providing a possible candidate for dark matter. ATLAS’s new searches targeted charginos and neutralinos – the heavy superpartners of force-carrying particles in the Standard Model – and sleptons – the superpartners of Standard Model matter particles called leptons. If produced at the LHC, these particles would each transform, or “decay”, into Standard Model particles and the lightest neutralino, which does not further decay and is taken to be the dark-matter candidate.

ATLAS’s newest search for charginos and sleptons studied a particle-mass region previously unexplored due to a challenging background of Standard Model processes that mimics the signals from the sought-after particles. The ATLAS researchers designed dedicated searches for each of these SUSY particle types, using all the data recorded from Run 2 of the LHC and looking at the particles’ decays into two charged leptons (electrons or muons) and “missing energy” attributed to neutralinos. They used new methods to extract the putative signals from the background, including machine-learning techniques and “data-driven” approaches.

Humans Disrupting 66 Million-Year-Old Fundamental Feature of Ecosystems — “This Hasn’t Happened Before”

Posted by in category: food

According to a new study, the U-shaped association between diet and size in modern land mammals could also stand for “universal,” as the relationship covers at least 66 million years and a range of vertebrate animal groups.

It’s been several decades since ecologists realized that graphing the diet-size relationship of terrestrial mammals yields a U-shaped curve when aligning those mammals on a plant-to-protein gradient. As illustrated by that curve, the plant-eating herbivores on the far left and meat-eating carnivores on the far right tend to grow much larger than those of the all-consuming omnivores and the invertebrate-feasting invertivores in the middle.

Evidence suggests cancer is not as purely genetic as once thought

New evidence shows that cancer is not as heritable or purely genetic as once thought, and taking a multi-omics approach may lead to a better understanding of how to prevent and treat it.

A New Billion-Year History of Earth’s Interior Reveals Colossal ‘Blobs’ Merging and Breaking Apart Like Continents

Posted by in category: futurism

The blobs are in the mantle, the thick layer of hot rock between Earth’s crust and its core. The mantle is solid but slowly flows over long timescales. We know the blobs are there because they slow down waves caused by earthquakes, which suggests the blobs are hotter than their surroundings.

Scientists generally agree the blobs are linked to the movement of tectonic plates at Earth’s surface. However, how the blobs have changed over the course of Earth’s history has puzzled them.
