Protein Data Bank - RCSB PDB. A Structural View of Biology This resource is powered by the Protein Data Bank archive-information about the 3D shapes of proteins, nucleic acids, and complex assemblies that helps students and researchers understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease.
As a member of the wwPDB, the RCSB PDB curates and annotates PDB data. The RCSB PDB builds upon the data by creating tools and resources for research and education in molecular biology, structural biology, computational biology, and beyond. Use this website to access curated and integrated biological macromolecular information in the context of function, biological processes, evolution, pathways, and disease states.

Teeth marks. Photos by Graham Chedd (PBS); Paul Tafforeau (ESRF); and Tanya Smith (Harvard University and MPI-EVA) “Teeth are remarkable time recorders, capturing each day of growth much like rings in trees reveal yearly progress,” says Tanya M.
Smith, assistant professor of human evolutionary biology at Harvard. A sophisticated new examination of teeth from 11 Neanderthal and early human fossils shows that modern humans are slower than our ancestors to reach full maturity. The finding suggests that our slow development and long childhood are recent and unique to our own species, and may have given early humans an evolutionary advantage over Neanderthals. The research, led by scientists at Harvard University, the Max Planck Institute for Evolutionary Biology (MPI-EVA), and the European Synchrotron Radiation Facility (ESRF), is detailed in the Proceedings of the National Academy of Sciences.

This ScienceLives article was provided to LiveScience in partnership with the National Science Foundation. The Internet is a sociologist's playground, says Scott Golder, a graduate student in sociology at Cornell University.
Although sociologists have wanted to study entire societies in fine-grained detail for nearly a century, they have had to rely primarily upon large-scale surveys (which are costly and logistically challenging) or interviews and observations (which provide rich detail, but for small numbers of subjects). Golder hopes that data from the social Web will provide opportunities to observe the detailed activities of millions of people, and he is working to bring that vision to fruition. The same techniques that make the Web run—providing targeted advertisements and filtering spam—can also provide insights into social life. For example, he has used Twitter archives to examine how people’s moods vary over time, as well as how network structure predicts friendship choices.
