Writer Fuel: Scientists Create AI Models That Can Train Each Other – What Could Possibly Go Wrong?

ai - deposit photos

The next evolution in artificial intelligence (AI) could lie in agents that can communicate directly and teach each other to perform tasks, research shows. Scientists have modeled an AI network capable of learning and carrying out tasks solely on the basis of written instructions. This AI then described what it learned to a “sister” AI, … Read more

Writer Fuel: One in Twelve “Twin” Stars Has Likely Eaten a Planet

About one in every 12 stars may have swallowed a planet, a new study finds. Previous research had discovered that some distant stars possess unusual levels of elements, such as iron, which one would expect to make up rocky worlds such as Earth. This and other evidence suggested that stars may sometimes ingest planets, but much remained uncertain … Read more

The moon is much more seismically active than we realized, a new study shows. A reanalysis of abandoned data from NASA’s Apollo missions has uncovered more than 22,000 previously unknown moonquakes — nearly tripling the total number of known seismic events on the moon. Moonquakes are the lunar equivalent of earthquakes, caused by movement in … Read more

Microplastics may hang around in the body longer than scientists previously thought and may contribute to the spread of cancer when inside tumors, a lab-dish study suggests. The research has several limitations, however. For instance, the scientists used cancer cells grown in lab dishes, so it remains to be seen how the results apply to … Read more

Writer Fuel: The Theory of “Emergent Gravity,” Explained

gravity - deposit photos

In 2009, theoretical physicist Erik Verlinde proposed a radical reformulation of gravity. In his theory, gravity is not a fundamental force but rather a manifestation of deeper hidden processes. But in the 15 years since then, there hasn’t been much experimental support for the idea. So where do we go next? Emergence is common throughout … Read more

Nearly four years after NASA’s OSIRIS-Rex spacecraft collected a sample from an asteroid, scientists are finally revealing the intriguing composition of the space rock. Among them, the near-Earth asteroid, known as Bennu, contains a surprising reservoir of a mineral called magnesium phosphate. These bright-white particles sprinkled in a sea of Bennu’s dark rocks is a … Read more

Writer Fuel: Why Aren’t All Orbits Circular?

orbits - deposit photos

Many maps of the solar system make it look as though everything in space moves in perfect, concentric circles. Planets orbit the sun, and moons orbit the planets. So that must be the case for everything in space, right? Not quite. Orbits form all sorts of shapes. “Planets and other bodies rarely go around in … Read more

Writer Fuel: Giant Volcano Discovered Hiding In Plain Sight on Mars

Giant Volcano - Mars

Scientists have discovered a giant volcano on Mars that has been “hidden in plain sight” for more than 50 years. The volcano is around 280 miles (450 kilometers) wide and more than 29,600 feet (9,000 meters) high. It is located in the eastern part of Mars’ Tharsis volcanic province near the planet’s equator, scientists revealed … Read more

Writer Fuel: Are “Unparticles” Pushing the Universe Apart?

The ever-accelerating expansion of the universe may be driven by a mysterious form of matter called “unparticles,” which do not obey the Standard Model of particle physics, a new theoretical paper suggests. Scientists widely acknowledge that the universe is expanding, though the cause of that expansion remains elusive. One of the most popular proposed explanations … Read more

Writer Fuel: Mars May Affect Our Climate – Every 2.4 Million Years

Mars - Deposit Photos

Mars’ gravitational pull on Earth may be influencing the climate on our planet, new research hints. Geological evidence tracing back more than 65 million years and taken from hundreds of sites across the world suggests that deep-sea currents have repeatedly gone through periods of being either stronger or weaker. This happens every 2.4 million years … Read more
