Scientists have found that the early universe, and the very first galaxies, would have looked very different depending on the nature of dark matter. For the first time, the team has simulated what early galaxy formation would have looked like if dark matter were ''fuzzy,'' rather than cold or warm.
Read moreNew research has simulated dark matter in a new way for the first time, disrupting conventional thinking about the make-up of the universe.
Read moreAccurately measuring frequencies of light is required for timekeeping and many science experiments and technologies. Frequency combs, invented in 2000, are used to complete these measurements. However, most of them are large and cumbersome. In 2009, researchers developed a way to make much smaller combs, but they came with their own challenges. New research finds that a novel way of generating frequency combs could address these challenges, leading to compact frequency combs with untold applications.
Read moreA research team has invented a semiconductor quantum well system that can efficiently cool electronic devices using established fabrication methods. This work can allow for smaller and faster smart devices that consume less power.
Read moreA team of scientists has made the strongest silver ever — 42 percent stronger than the previous world record. It's part of a discovery of a new mechanism at the nanoscale that can create metals much stronger than any ever made before — while not losing electrical conductivity.
Read moreA nuclear war between India and Pakistan could, over the span of less than a week, kill 50-125 million people — more than the death toll during all six years of World War II, according to new research.
Read moreA new way to calculate the interaction between a metal and its alloying material could speed the hunt for a new material that combines the hardness of ceramic with the resilience of metal.
Read moreQuantum physics is difficult and explaining it even more so. Researchers have now tried to solve one of the biggest puzzles in quantum physics: How to measure the quantum system without changing it?
Read moreAccording to quantum physics, energy can be 'borrowed' — at least for some time. Energies lower than zero are possible, much like a bank account that can be overdrawn. There are, however, certain restrictions to that. Scientists have now shown that these restrictions are very fundamental properties of our universe and must be true for various possible quantum theories.
Read moreThe quantum superposition principle has been tested on a scale as never before in a new study. Hot, complex molecules composed of nearly two thousand atoms were brought into a quantum superposition and made to interfere. By confirming this phenomenon — 'the heart of quantum mechanics', in Richard Feynman's words — on a new mass scale, improved constraints on alternative theories to quantum mechanics have been placed.
