From Belgrade to Berkeley: A Postdoctoral Researcher’s Path in Particle Physics

After completing her Ph.D. thesis in calculating the mass of the W boson – a heavier-than-iron elementary particle that mediates one of the universe’s fundamental forces – physics researcher Aleksandra Dimitrievska is now testing components at Berkeley Lab for a scheduled upgrade of the world’s largest particle detectors.

Solving the Dark Energy Mystery: A New Assignment for a 45-Year-Old Telescope

Today, the dome closes on the previous science chapters of the 4-meter Mayall Telescope in Arizona so that it can prepare for its new role in creating the largest 3-D map of the universe. This map could help to solve the mystery of dark energy, which is driving the accelerating expansion of the universe.

Applying Machine Learning to the Universe’s Mysteries

Berkeley Lab physicists and their collaborators have demonstrated that computers are ready to tackle the universe’s greatest mysteries – they used neural networks to perform a deep dive into data simulating the subatomic particle soup that may have existed just microseconds after the big bang.

It All Starts With a ‘Spark’: Berkeley Lab Delivers Injector That Will Drive X-Ray Laser Upgrade

A team at Berkeley Lab has designed, built, and delivered a unique version of a device, called an injector gun, that can produce a steady stream of these electron bunches. The gun will be used to produce brilliant X-ray laser pulses at a rapid-fire rate of up to 1 million per second.

X-Rays Reveal ‘Handedness’ in Swirling Electric Vortices

Scientists used spiraling X-rays at Berkeley Lab to observe, for the first time, a property that gives left- or right-handedness to swirling electric patterns – dubbed polar vortices – in a layered material called a superlattice.

How the Earth Stops High-Energy Neutrinos in Their Tracks

In an analysis of data from an experiment embedded in Antarctic ice, a research collaboration including scientists from Berkeley Lab has demonstrated that the Earth stops high-energy neutrinos – particles that only very rarely interact with matter.

A Flight Path to Physics Success

In a previous career with the U.S. Air Force, Sandra Miarecki flew high above the Earth’s surface. She retired from the Air Force in 2007 to pursue a new calling in physics that would set her sights on particles traveling into the depths of the Earth.

Scientists Decode the Origin of Universe’s Heavy Elements in the Light from a Neutron Star Merger

On Aug. 17, scientists around the globe were treated to near-simultaneous observations by separate instruments that would ultimately be confirmed as the first measurement of the merger of two neutron stars and its explosive aftermath.

Berkeley Lab Intern Focuses on Using Light for Spaceflight

Elliot Heywood had dreamed of landing an internship at the science lab in the hills not far from his school in Lafayette, California, but he never could have imagined this dream would take wing as a summerlong stint researching an ultrafast interplanetary propulsion system. In May, after a friend and fellow high school senior at

Dark Matter Day Is Approaching … but Don’t Be Afraid of the Dark

A global hunt for the universe’s missing matter is underway, and this autumn everyone is invited to join in. On and around October 31, 2017, events around the world will celebrate the hunt for the universe’s unseen “dark matter.”
