As we push the Periodic Table of the Elements further and further into the unknown, its familiar columns and rows are threatening to crumble. What’s next for this science icon? Superheavy elements exist for a fraction of time and are nearly impossible to catch. But understanding them could force us to reimagine the most iconic scientific symbol of all time..
Eric Seaborg, a writer and author, outdoorsman and environmentalist, has a love for hiking that he shared with his father, the late chemist and Nobel laureate Glenn Seaborg (1912-1999) who blazed trails in element and isotope discoveries during an illustrious career at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley.
Glenn Seaborg was born too late to have spawned Cal’s spirit cry. It’s coincidence, surely, that his name is an anagram for “Go Bears!” And, although he was definitely a Bears fan and was Chancellor when Cal last made it to the Rose Bowl in 1959, he was never in Oski’s league as a campus celebrity. While others led rallies, he had to settle for spearheading decades of trailblazing nuclear science, endowing UC Berkeley with bragging rights to the discovery of a record 16 new elements. Now, though, the 1951 Nobelist is making a bid to play in the social media space.
When chemist Rebecca Abergel (Ph.D. '06, Chem) and her team at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory successfully developed an anti-radiation-poisoning pill in 2014, they hoped it would never have to be used. Now the researchers are studying how that very same pill could help protect people from the potential toxicity of something else – the long-term retention of gadolinium, a critical ingredient in widely used contrast dyes for MRI (magnetic resonance imaging) scans.

The periodic table is chemistry’s holy text. Not only does it list all of the tools at chemists’ disposal, but its mere shape – where these elements fall into specific rows and columns – has made profound predictions about new elements and their properties that later came true. But few chemists on Earth have a closer relationship with the document than Dawn Shaughnessy, whose team is partially responsible for adding six new elements to table’s ranks.
New research from Lawrence Berkeley National Laboratory has been published in "Chemistry: a Europena Journal" about two elements discovered at Berkeley: Berkelium and Californium. Researchers show that berkelium and californium, two elements in the actinide series (elements 89 to 103), have a surprisingly stable +5 oxidation state.
