A Cloud of Tags at your Fingertips: Most are familiar with tag/word clouds for individual documents. DOE R&D Accomplishments has a Tag Cloud that is not your ordinary tag cloud. It’s a different kind of tag cloud because it is for the entire Database. You can easily explore the Database via the terms in this interactive Tag Cloud. More Information

It’s a Family Matter! The third family of fundamental particles of matter became more than just a theory with the discovery of the tau lepton by Martin Perl. It is the 20th Anniversary of Perl receiving the Nobel Prize in Physics for his discovery, which took place 40 years ago (1975). Evidence of this third family of fundamental particles inspired confidence in the Standard Model, the theory being developed in the 1970s by physicists to explain matter and the forces of nature.

Following the Path of Carbon in Photosynthesis: At the suggestion of E. O. Lawrence, then Director of UC Berkeley’s Radiation Laboratory (predecessor of Lawrence Berkeley National Laboratory), 70 years ago Melvin Calvin began his historical research about carbon dioxide assimilation in plants. The result was a series of more than 20 publications, from 1948 through his Nobel Lecture in 1961, about unraveling the secrets of photosynthesis -- the process by which green plants convert sunlight energy into chemical energy. Calvin's work in deciphering the role of carbon in photosynthesis led to a lifelong interest in adapting photosynthetic techniques for energy production. More Information

June 2015 is the thirty-fifth anniversary of the Science article about why dinosaurs are extinct. Entitled “Extraterrestrial Cause for the Cretaceous-Tertiary Extinction”, it was co-written by Nobel Laureate Luis Alvarez, a former researcher at Lawrence Berkeley National Laboratory (LBNL). The Death of the Dinosaurs is also addressed in an LBNL Summer Lecture Series.

Twenty years ago, the top quark was first observed in experiments at the Tevatron proton-antiproton collider at Fermilab. Even with the energies available in the Tevatron and with the most sophisticated detectors, the top was hard to find. After a top is made from a proton-antiproton collision, a rare event itself, it exists for such a short time that it cannot be directly observed. Rather, the products of top decay are identified and traced back to the top after extensive computer analysis.
