Getting beyond numerology

Article Abstract:

Geophysicists and seismologists are conducting extensive studies to better understand the seismic cycle governing the ruptures of the San Andreas fault at Parkfield, CA. The site features ruptures created by earthquakes of magnitude 6 which occurred at regular intervals of 22 plus-minus 6 years of each other. Although the earthquake predicted using this model in 1992 failed to take place, scientists continued to come up with new models on the cycle and the nucleation of characteristic earthquakes. These include a viscoelastic fault model developed by Havard researchers and a model which focuses on slips on the fault plane minimizing the difference between two earthquake events.

Lipids beyond the bilayer

Article Abstract:

The three-dimensional water-lipid systems devised by Landau and Rosenbusch have been used to investigate the structure of the membrane proteins that are embedded within a bilipid layer as well as the significance of the non-bilayer lipids in the membranes. Results have shown that the functional structure of a protein will be better preserved within the cubic phase which can only be formed with substantial amounts of non-bilayer lipids. These non-bilayer lipids are usually needed for functional reconstitution of membrane proteins.

Schools at 10(super 20) eV and beyond

Article Abstract:

The high-school project on astrophysics research with cosmics (HISPARC) explores a research frontier and attracts high-school students of both sexes and diverse ethnicities. According to its coordinators, a key to the project's motivational success is that the schools become stakeholders by working with researchers in constructing the detectors.
