Part of that photograph shows the central uplift structure in the crater. Rocks that form this peak were several kilometers beneath the surface until an impact formed the 37 mile-diameter (60 kilometer) crater just north of Mars' equator. The HiRISE image shows that boulders as large as 50 feet across (15 meters) have eroded from the massive uplifted rock and rolled downslope.
The HiRISE image also confirms earlier evidence that this part of Mojave crater appears untouched by liquid water. Previous photographs taken by the HiRISE camera, and even earlier by the Mars Orbital Camera that flew on NASA'S Mars Global Surveyor, show that Mojave crater rim walls feature striking drainage channels and alluvial fans that likely were formed by surface water runoff. How runoff formed these channels and alluvial fans is one of the questions that HiRISE team members and their collaborators are looking into.
The High Resolution Science Imaging Experiment (HiRISE) team, led by University of Arizona Professor Alfred S. McEwen, is based at UA's Lunar and Planetary Laboratory in Tucson. HiRISE began the science phase of the mission in November, 2006, and posts new images and captions on the Internet at http://hirise.lpl.arizona.edu every Wednesday.
More information about the Mars Reconnaissance Orbiter mission is available at http://www.nasa.gov/mro. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems, Denver, is the prime contractor for the project and built the spacecraft. The HiRISE camera was built by Ball Aerospace and Technologies Corp., Boulder, Colo.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
