The public understanding of science

Abstract: Both in Britain and the United States the public says it is more interested in science than (for example) sport. Public knowledge of science gives less cause for gratification.

Worlds Apart? The Reception of Genetically Modified Foods in Europe and the U.S.

Abstract: Recent controversies about genetically modified foods in the United Kingdom and several other European countries highlight the apparent differences that exist in public opinion on this subject across the Atlantic. Why are people in the United States seemingly untroubled by a technology that causes Europeans so many difficulties? The results of survey research on public perceptions of biotechnology in Europe and the United States during 1996-1997, together with an analysis of press coverage and policy formation from 1984 to 1996, can help to answer this question.

The Structure and Distribution of the Flavonoids in Plants

Abstract: -C3-C6 skeleton, have been found in plants, and are divided into several classes, i.e., anthocyanins, flavones, flavonols, flavanones, dihydroflavonols, chalcones, aurones, flavan and proanthocyanidins, isoflavonoids, biflavonoids, etc. In this review, the chemical structures of the reported flavonoid classes are introduced and their distribution in nature are described. Additionally, some recent chemotaxonomical examples using the flavonoids are also given.

Collisional growth conditions for dust aggregates

Abstract: Collisions between dust aggregates are the key to understand the formation of planetesimals because the collision inevitably takes place in protoplanetary disks. To clarify whether or not dust aggregates can grow through their mutual collisions at relatively high velocities, we carry out more than 4000 runs of three-dimensional numerical simulations of collisions between icy equal-mass clusters formed under ballistic particle-cluster aggregation (BPCA) as well as those of ballistic cluster-cluster aggregation, including offset collisions with various values of the impact parameter. Since our BPCA clusters have a fractal dimension of 3 and a relatively compact structure, their results enable us to determine the criteria for growth and disruption of compressed aggregates at their collisions in protoplanetary disks. The results show that ice dust aggregates are able to grow at collisions with velocities up to 50 m s–1, in spite of their initial structures and impact parameters. We also find that the mass of ejecta relative to the total mass of colliding aggregates decreases with increasing the size of the aggregates. These results demonstrate the feasibility of growth and survival for dust aggregates through their mutual collisions with relatively high velocities in protoplanetary disks.
