Twin research in Brazil twin has expanded enormously in recent years, engaging the interests and efforts of many investigators, students and twins. Descriptions and brief summaries of this work and talks given by investigators at local conferences are presented, based on my four-city lecture tour. This is followed by summaries of twin research on infants’ viewing of social scenes, religiosity and substance abuse, Down syndrome, and chronic periodontitis. This article concludes with twin-related news and information of general interest, including identical twin property designers, twins with cerebral palsy, twins affected with the Zika virus, a pair of twin writers, twins in sports, and a set of quadruplets from my childhood neighborhood in Riverdale, New York.

Highlights from a conference, ‘Healthier Kids: Insights From Twin Research’, held in Melbourne, Australia on December 5, 2014, are summarized. In addition to informative and exciting presentations and discussions of recent findings, three key themes emerged: (1) results from twin research have important implications for non-twins, (2) researchers from diverse disciplines should be encouraged to participate actively in twin research, and (3) investigators, twins and families need to work more collaboratively. Next, papers and studies concerning the biological bases of monozygotic (MZ) twinning, gestational diabetes and post-partum depression are reviewed. Finally, general interest reports of rare quadruplets, mistaken identity, prenatal laser surgery and a royal twin birth are provided.

The late neurologist and author, Oliver Sacks, published an insightful 1986 review of Marjorie Wallace's book, The Silent Twins, in the New York Times. Taking exception to his assertion about Sir Francis Galton, I wrote a letter to the Times’ editor. The letter was unpublished, but it brought a wonderful response from Sacks himself that is reproduced and examined. Next, brief reviews of twin research concerning the vanishing twin syndrome (VTS), discordant sex in a monozygotic (MZ) twin pair, and multiple pregnancy outcomes from assisted reproductive technology (ART) are presented. This section is followed by popular coverage of superfetated twins, smoking-discordant co-twins, twins in fashion, Yale University twin hockey players, and a visiting professor who was a conjoined twin.

Two points of general interest in structural refinement of polymers based on internal coordinates are discussed: the chain orientation and the chain continuity. Using a proprietary computer program, based on revised approaches to these questions, the structure of polyisobutene has been reconsidered, using new X-ray diffraction measurements (Fuji image plate) and performing a structure refinement based on internal coordinates. Three refinement schemes, with a decreasing number of degrees of freedom, have been considered, with the conclusion that the distortion from the 83regular helix, claimed by Tadokoro [(1979).Structure of Crystalline Polymers, p. 136. New York: Wiley-Interscience], is confirmed, though lower than supposed. The new procedures implemented for chain orientation and chain continuity work excellently.

This report describes the findings and interim results of a follow-up study of 770 children with cerebral palsy who were cared for under the aegis of the New York City Financial Aid Program from 1945 to July 1, 1954. The findings seem to indicate that some redirection of the program to include development, expansion and improvement of some alternate services within the community is advisable. It is likely that this same type of follow-up study would be of equal value for children of other diagnostic groups, and similar studies might be initiated.

The purpose of this paper is to review the most representative studies of the last decade (2006-2015) which deal with the combination of technology and music and concern individuals with Generic learning disabilities. Particularly, the areas of needs in this paper are divided to the following categories: Depression/ disruptive behavior, Down syndrome, Intellectual disa¬bilities, Cerebral palsy and Severe/Profound disa-bilities. It is also underlined the important role of Information and Communication Technologies (ICTs) and digital music tools in promoting musical participation and as-sisting students with the pre-referred disa-bilities.
