A group of scientists at The Scripps Research Institute has developed a new way of looking at and interacting with molecules so small that they cannot be seen even with the world’s most powerful microscopes.

The majority of information in the biological literature resides in full text articles, instead of abstracts. Yet, abstracts remain the focus of many publicly available literature data mining tools. Most literature mining tools rely on pre-existing lexicons of biological names, often extracted from curated gene or protein databases. This is a limitation, because such databases have low coverage of the many name variants which are used to refer to biological entities in the literature.

Millions of painted lady butterflies that fluttered into California's Central Valley in the last week of March could be just the advance guard of one of the largest migrations of the species on record, said Arthur Shapiro, a professor and expert on butterflies at UC Davis.

Bacteria acquired up to 90 percent of their genetic material from distantly related bacteria species, according to new research from The University of Arizona in Tucson.
