2editor's note-jan-june2016.pmd 1 FROM THE EDITOR ISSN 0115-7809 Print/ISSN 2012-0818 Online In this June 2016 issue of Science Diliman, we feature three research articles, one short communication, and a review. The three research articles addressed problems related to coffee, natural rubber, and the natural environment, whereas the contents of the review and short communication are pertinent to our seaweed industry. With the commercial importance of coffee in mind, authors Santos, Besa, Victoria, and Cao used simple sequence repeat (SSR) markers to correctly identify the varieties Arabica, Robusta, and Liberica. The correct identification of coffee varieties increases their market value. The research of Lamorena- Lim and Rosales determined the potential risks brought about by inhalable or airborne particulate matter at places within the vicinity of a landf ill facility. The paper by Pajarito, Berba, Par to, and Yabut detailed the blooming behavior of paraff in wax in natural rubber composites as a function of three types of zeolite treatment. The research group of Santiañez, Suan-Flandez, and Trono, Jr. described the occurrence and detrimental effects of white rot disease and epiphyte infection on cultured red seaweed. We also celebrate the retirement from the University of the Philippines of our immediate past Editor-in-Chief, Academician Marco Nemesio E. Montaño, with a review, albeit incomplete, of his research on post-harvest technology. Most of his work was done in conjunction with the research on seaweed production of National Scientist Gavino C. Trono, Jr. and co-authors. Irene M. V illaseñor, Ph.D. Editor-in-Chief
