Under pressure: Researchers compress copper, creating the densest object on Earth
Lawrence Livermore National Laboratory

If copper was found in the core of Saturn it would have the same crystalline structure as the copper pipes found in many homes, according to new research from Lawrence Livermore National Laboratory (LLNL) and Johns Hopkins University. In a paper published today by Physical Review Letters, the research team reveals that copper maintains its crystalline structure at pressures ranging from one atmosphere (room pressure) to more than 30 million atmospheres.

Top-10 Science and Technology Achievements of 2019
Brookhaven National Laboratory

In 2019, scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory dove deeper into proton spin, took a leap in quantum communication, and uncovered new details of plant biochemistry, battery cathodes, catalysts, superconductors, and more. Here, in no particular order, are the biggest advances of the year.

Researchers Discover Highest-Energy Light From a Gamma-ray Burst
George Washington University

An international team of researchers, including two astrophysicists from the George Washington University, has observed a gamma-ray burst with an afterglow that featured the highest energy photons—a trillion times more energetic than visible light—ever detected in a burst.

Space Telescope Science Institute (STScI)

NASA’s Hubble Space Telescope has given astronomers a peek at the location of the most energetic outburst ever seen in the universe—a blast of gamma-rays a trillion times more powerful than visible light. That’s because in a few seconds the gamma-ray burst (GRB) emitted more energy than the Sun will provide over its entire 10-billion year life.

3D-Printed Plastics With High Performance Electrical Circuits
Rutgers University-New Brunswick

Rutgers engineers have embedded high performance electrical circuits inside 3D-printed plastics, which could lead to smaller and versatile drones and better-performing small satellites, biomedical implants and smart structures. They used pulses of high-energy light to fuse tiny silver wires, resulting in circuits that conduct 10 times more electricity than the state of the art, according to a study in the journal Additive Manufacturing. By increasing conductivity 10-fold, the engineers can reduce energy use, extend the life of devices and increase their performance.

Zinc-anode batteries prove their mettle
Cornell University

Researchers working with Lynden Archer, Cornell’s James A. Friend Family Distinguished Professor of Engineering, have found a way to build a zinc-anode battery that not only has a high energy density, but is low cost, robust and stable, and has a life cycle that can be significantly prolonged.
