Shown is a graphic depicting the newest elements on the peiodic table, Flerovium - element 114 with the symbol Fl, and Livermorium - element 116, with the symbol Lv.


Scientists of the Lawrence Livermore National Laboratory (LLNL)-Dubna collaboration proposed the names as Flerovium for element 114, with the symbol Fl, and Livermorium for element 116, with the symbol Lv, in 2011.

Laboratory researchers find Earth composed of different materials than primitive meteorites 

September 15, 2016

Scientists from Lawrence Livermore National Laboratory have found that, contrary to popular belief, the Earth is not comprised of the same material found in primitive meteorites (also known as chondrites).

Lawrence Livermore credited with discovery of elements 115, 117 and 118 

December 31, 2015

The International Union of Pure and Applied Chemistry (IUPAC) has confirmed that Lawrence Livermore National Laboratory scientists and international collaborators have officially discovered elements 115, 117 and 118.

New results from experimental facility deepen understanding of dark matter 

December 29, 2015

The Large Underground Xenon (LUX) dark matter experiment, which operates nearly a mile underground at the Sanford Underground Research Facility (SURF) in the Black Hills of South Dakota, has already proven itself to be the most sensitive dark matter detector in the world. Now, a new set of calibration techniques employed by LUX scientists has further improved its sensitivity.

New 'stealth dark matter' theory may explain mystery of the universe's missing mass 

September 24, 2015

Lawrence Livermore National Laboratory (LLNL) scientists have come up with a new theory that may identify why dark matter has evaded direct detection in Earth-based experiments.

Researchers have identified a unique chemical signature left by the earliest stars in the universe with the first direct measurement under stellar conditions of an important nuclear reaction.

First stars in the universe left a unique signature 

June 29, 2015

Determining the chemical abundance pattern left by the earliest stars in the universe is no easy feat. A Lawrence Livermore National Laboratory (LLNL) scientist is helping to do just that.

Fans of the popular TV series "CSI" know that the forensics experts who investigate crime scenes are looking for answers to three key questions: "Who did it; how did they do it; and can we stop them from doing it again?"

Shown is a top-down view of the LLNL-designed and built copper photomultiplier tube mounting structure, which is a key component of the LUX detector.
