Alexander Dalgarno

Alexander Dalgarno: From atomic and molecular physics to astronomy and aeronomy.

As Sir David Bates wrote in 1988, “There is no greater figure than Alex Dalgarno in the history of atomic-molecular-optical [AMO] physics, and its applications” (1). Prof. Alexander Dalgarno (Harvard) passed away peacefully on April 9, 2015 at age 87 in the presence of his long-term companion, Fern Creelan. During a career spanning 60 years, Alex produced about 750 publications covering a vast ...

Selection of Shine-Dalgarno sequences in plastids

Like bacterial genes, most plastid (chloroplast) genes are arranged in operons and transcribed as polycistronic mRNAs. Plastid protein biosynthesis occurs on bacterial-type 70S ribosomes and translation initiation of many (but not all) mRNAs is mediated by Shine-Dalgarno (SD) sequences. To study the mechanisms of SD sequence recognition, we have analyzed translation initiation from mRNAs contai...

As a former student of Professor Ostrowski—one of his last— I am delighted to recall here the life and work of one of the great mathematicians of the 20th century. Needless to say that, in view of Ostrowski’s immense and vastly diverse mathematical legacy, this can be done only in a most summary fashion. Further literature on Ostrowski can be found in some of the references at the end of this a...
