Since the first sighting of the first-discovered and largest asteroid in our solar system was made in 1801 by Giuseppe Piazzi, astronomers and planetary scientists have pondered the make-up of this asteroid/dwarf planet. Its heavily battered and dimpled surface is covered in impact craters. Scientists have long argued that visible craters on the surface meant that Ceres could not be very icy.
Researchers at Purdue University and the NASA’s Jet Propulsion Lab (JPL) now believe Ceres is a very icy object that possibly was once a muddy ocean world. This discovery that Ceres has a dirty ice crust is led by Ian Pamerleau, Ph.D. student, and Mike Sori, assistant professor in Purdue’s Department of Earth, Atmospheric, and Planetary Sciences who published their findings in Nature Astronomy. The duo along with Jennifer Scully, research scientist with JPL, used computer simulations of how craters on Ceres deform over billions of years.
“We think that there’s lots of water-ice near Ceres surface, and that it gets gradually less icy as you go deeper and deeper,” Sori said. “People used to think that if Ceres was very icy, the craters would deform quickly over time, like glaciers flowing on Earth, or like gooey flowing honey. However, we’ve shown through our simulations that ice can be much stronger in conditions on Ceres than previously predicted if you mix in just a little bit of solid rock.”
Cleveland Clinic researchers have discovered a new bacterium that weakens the immune system in the gut, potentially contributing to certain inflammatory and infectious gut diseases.
The team identified the bacterium, Tomasiella immunophila (T. immunophila), which plays a key role in breaking down a crucial immune component of the gut’s multi-faceted protective immune barrier.
Identifying this bacterium is the first step to developing new treatments for a variety of inflammatory and infectious gut diseases. These conditions, including inflammatory bowel disease, Crohn’s and ulcerative colitis, are associated with decreased levels of secretory immunoglobulin A (SIgA), an antibody that protects mucosal surfaces.

Scientists have identified previously unreported genes which appear to play a key role in the muscle aging process. It is hoped that the findings from a Nottingham Trent University study could be used to help delay the impact of the aging process.
The study, which also involved Sweden’s Karolinska Institute, Karolinska University Hospital, and Anglia Ruskin University, is reported in the Journal of Cachexia, Sarcopenia and Muscle.
