Two teams of researchers who made national headlines in April for showing the first evidence of water ice and organic molecules on an asteroid have now discovered that asteroid 65 Cybele contains the same material.
"This discovery suggests that this region of our solar system contains more water ice than anticipated," said University of Central Florida Professor Humberto Campins. "And it supports the theory that asteroids may have hit Earth and brought our planet its water and the building blocks for life to form and evolve here."
Campins will present the teams' findings during the 42nd-annual Division of Planetary Sciences Conference (http://dps.aas.org/meetings/2010) in Pasadena, Calif., which concludes Oct. 8.
Asteroid 65 Cybele is somewhat larger than asteroid 24 Themis – the subject of the teams' first paper. Cybele has a diameter of 290 km (180 miles). Themis has a diameter of 200 km (124 miles). Both are in the same region of the asteroid belt between Mars and Jupiter.
The academic article reporting this new finding has been accepted for publication in the European Journal "Astronomy and Astrophysics."
Campins is an expert on asteroids and comets. He received national attention for an article published in Nature showing the first evidence of water ice and organic molecules on asteroid 24 Themis. He's also worked on several science missions with NASA and the European Space Agency.
Campins holds degrees from the University of Kansas and the University of Arizona. He joined UCF in 2002 as the Provost Research Professor of Physics and Astronomy and head of the Planetary and Space Science Group.
UCF Stands For Opportunity --The University of Central Florida is a metropolitan research university that ranks as the 3rd largest in the nation with more than 56,000 students. UCF's first classes were offered in 1968. The university offers impressive academic and research environments that power the region's economic development. UCF's culture of opportunity is driven by our diversity, Orlando environment, history of entrepreneurship and our youth, relevance and energy.

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...
