Fusion Ignition Repeated for Second Time by U.S. Scientists, Marking New Era in Energy Research

In a groundbreaking feat, scientists at the Lawrence Livermore National Laboratory have accomplished a second instance of net energy gain in a fusion reaction, confirming the feasibility of this potentially revolutionary power source. The breakthrough comes eight months after the lab’s initial success, suggests a turning point in the quest for limitless clean energy. The laboratory, based in California, achieved this milestone in a series of experiments conducted at the National Ignition Facility (NIF) on July 30. Preliminary assessments indicate the fusion reaction produced a greater energy yield than the first experiment in December 2022, though the laboratory is still

What is a room temperature superconductor?

For over a century, scientists have been in relentless pursuit of a material that could perfectly conduct electricity. The quest to find a room-temperature superconductor, a material that can carry an electrical charge with zero resistance at everyday temperatures, has been a saga filled with painstaking experiments, complex theories, and scientific disputes. Recent findings on the material known as LK-99 have once again stirred the pot of controversy. Researchers claim to have achieved room-temperature superconductivity, though the paper awaits rigorous peer review. But what even is room-temperature superconductor, and why does it matter? The Promise of Room-Temperature Superconductors According to

Mathematicians Bridge a Gap in Number Theory

Two mathematicians have proven an important result connecting elliptic curves to modular forms, extending a breakthrough achieved in the 1990s that led to the solution of Fermat’s Last Theorem. Ana Caraiani of Imperial College London and the University of Bonn, and James Newton of the University of Oxford announced in January that they had shown that elliptic curves are modular for certain imaginary quadratic fields. Their work builds on Andrew Wiles’ 1994 proof that elliptic curves are modular for rational numbers, meaning that for each elliptic curve, there exists a corresponding modular form — an object from analysis, a branch
