How to Catch a Perfect Wave: Scientists Take a Closer Look Inside the Perfect Fluid

Scientists have reported new clues to solving a cosmic conundrum: How the quark-gluon plasma – nature’s perfect fluid – evolved into the building blocks of matter during the birth of the early universe.

Is Gravity a Quantum Force?

Researchers at Berkeley Lab and the National Institute of Standards and Technology have proposed an experiment that may settle the persistent question: Is gravity truly a quantum force?

Supernovae Twins Open Up New Possibilities for Precision Cosmology

Cosmologists have found a way to double the accuracy of measuring distances to supernova explosions – one of their tried-and-true tools for studying the mysterious dark energy that is making the universe expand faster and faster.

Meteorites Reveal Magnetic Record of Protoplanet Churn

Researchers from MIT, Oxford, Arizona State, JPL, and Berkeley Lab detected the signatures of ancient magnetic fields imprinted in a meteorite’s ferromagnetic grains at Berkeley Lab’s Advanced Light Source (ALS).

Missing Baryons Found in Far-Out Reaches of Galactic Halos

Researchers have channeled the universe’s earliest light – a relic of the universe’s formation known as the cosmic microwave background (CMB) – to solve a missing-matter mystery and learn new things about galaxy formation. Their work could also help us to better understand dark energy and test Einstein’s theory of general relativity by providing new details about the rate at which galaxies are moving toward us or away from us.

AI Finds More Than 1,200 Gravitational Lensing Candidates

A research team with participation by Berkeley Lab physicists has used artificial intelligence to identify more than 1,200 possible gravitational lenses – objects that can be powerful markers for the distribution of dark matter. The count, if all of the candidates turn out to be lenses, would more than double the number of known gravitational lenses.

Study: X-Rays Surrounding ‘Magnificent 7’ May Be Traces of Sought-After Particle

A new study, led by a theoretical physicist at Berkeley Lab, suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars.

Building a Giant 2D Map of the Universe to Prepare for the Largest 3D Map

Before DESI, the Dark Energy Spectroscopic Instrument, can begin its 5-year mission from an Arizona mountaintop to produce the largest 3D sky map yet, researchers first needed an even bigger 2D map of the universe.

Know When to Unfold ’Em: Study Applies Error-Reducing Methods from Particle Physics to Quantum Computing

Borrowing a page from high-energy physics and astronomy textbooks, a team of physicists and computer scientists at Berkeley Lab has successfully adapted and applied a common error-reduction technique to the field of quantum computing.

A Major Milestone for an Underground Dark Matter Search Experiment

Crews working on the largest U.S. experiment designed to directly detect dark matter completed a major milestone last month, and are now turning their sights toward startup after experiencing some delays due to global pandemic precautions.
