The Gravity Research Foundation was founded by Roger W. Babson (1875- 1967) and the first awards for the best essays submitted on Gravity were made on December 1st, 1949. Since then, each edition has been a high level competition among scientists from all over the world, many times being the winners reputated scientists previously awarded Nobel Prizes. This year the ICCUB member, Joan Solà and the ICCUB collaborator Paul Towsend, have been selected for Honorable Mention, and their respective essays would be publish in a special number of the Gravity Research Foundation journal. Remarkable are also the 2 previous editions in which Dr. Solà was also recognized with this same mention. This third consecutive year it has been his essay titled "The cosmological constant and entropy problems: mysteries of the present with profound roots in the past" which has made him to receive again the honour mention.
