Dark energy vs. modified gravity: Which one will prevail?

Einstein's theory of general relativity predicts the existence of dark energy—a mysterious form of energy that permeates space and accelerates the expansion of the Universe. But what if Einstein was wrong and there was no ...

The Mesoamerican attraction to magnetism

The purpose of Mesoamerican potbelly statues have been the subject of debate among anthropologists for decades: Are they depictions of the ruling elite? A way to honor dead ancestors? Or perhaps portrayals of women giving ...

Improved model could help scientists better predict crop yield, climate change effects

A new computer model incorporates how microscopic pores on leaves may open in response to light—an advance that could help scientists create virtual plants to predict how higher temperatures and rising levels of carbon dioxide ...

Study suggests asteroids might play key role in spreading life

Picture this: A bacteria-carrying asteroid is ejected from the center of the galaxy into the far reaches of space only to be "captured" by a distant solar system, potentially bringing life to a new world.

Study unveils new supersymmetry anomalies in superconformal quantum field theories

Researchers at the University of Southampton and the Korea Institute for Advanced Study have recently showed that supersymmetry is anomalous in N=1 superconformal quantum field theories (SCFTs) with an anomalous R symmetry. ...

Model suggests how early dark energy could resolve the Hubble tension

The universe is continuously expanding, yet the exact rate at which it does so remains unclear, and has so far only been approximated using NASA's Hubble Space Telescope and other similar instruments. Moreover, in recent ...

Quantum—a double-edged sword for cryptography

Quantum computers pose a big threat to the security of modern communications, deciphering cryptographic codes that would take regular computers forever to crack. But drawing on the properties of quantum behaviour could also ...

Decoding Beethoven's music style using data science

EPFL researchers are investigating Beethoven's composition style using statistical techniques to quantify and explore the patterns that characterize musical structures in the Western classical tradition. They confirm what ...

Stabilizing the no-boundary proposal sheds light on the universe's quantum origins

One idea for how the universe began is that the universe may have appeared out of nothing due to some quantum effect, such as quantum tunneling. In the 1980s, Stephen Hawking and James Hartle further elaborated on this idea ...
