Developing a Textbook Evaluation Scheme for the Expanding Circle

Among the four important factors in the educational contexts, namely, teachers, learners, textbooks and contexts, textbooks play an important role in English Language Teaching (ELT), particularly in the English as a Foreign Language (EFL) classroom where it provides the primary source of linguistic input. The wealth of published material for English language teaching (ELT) available in the mark...

Desmophyllum dianthus (Esper, 1794) in the Scleractinian Phylogeny and Its Intraspecific Diversity

The cosmopolitan solitary deep-water scleractinian coral Desmophyllum dianthus (Esper, 1794) was selected as a representative model species of the polyphyletic Caryophylliidae family to (1) examine phylogenetic relationships with respect to the principal Scleractinia taxa, (2) check population structure, (3) test the widespread connectivity hypothesis and (4) assess the utility of different nuc...

Expanding the Biology Toolkit

Whether you call it biochemistry, molecular pharmacology, or chemical biology, one thing we can agree on is that chemists have long sought to advance the biological sciences. Through development of reagents, instruments, algorithms, and technologies, chemistry brings to biology the ability to drill down to molecules, bonds and atoms—the scale of matter at which all living things converge on com...

Expanding the genetic code.

Although chemists can synthesize virtually any small organic molecule, our ability to rationally manipulate the structures of proteins is quite limited, despite their involvement in virtually every life process. For most proteins, modifications are largely restricted to substitutions among the common 20 amino acids. Herein we describe recent advances that make it possible to add new building bl...
