Dark energy survey releases most precise look at the universe's evolution

In 29 new scientific papers, the Dark Energy Survey examines the largest-ever maps of galaxy distribution and shapes, extending more than 7 billion light-years across the Universe. The extraordinarily precise analysis, which includes data from the survey s first three years, contributes to the most powerful test of the current best model of the Universe, the standard cosmological model. However, hints remain from earlier DES data and other experiments that matter in the Universe today is a few percent less clumpy than predicted. ....

Cancer has been recently shown to be affected by protein clusters, particularly by the aggregation of mutant variants of the tumor suppressor protein p53, which are present in more than half of malignant tumors. However, how the aggregates are formed is not yet fully understood. The understanding of this process is expected to provide new therapeutic tools able to prevent proteins to clump and cancer progression.
In Brazil, researchers at the Federal University of Rio de Janeiro have identified a key mechanism behind the mutant p53 aggregation process, linked to cancer pathology, opening new paths for the development of novels drugs against the disease. ....

A combination of observational data and sophisticated computer simulations have yielded advances in a field of astrophysics that has languished for half a century. The Dark Energy Survey, which is hosted by the U.S. Department of Energy s Fermi National Accelerator Laboratory, has published a burst of new results on what s called intracluster light, or ICL, a faint type of light found inside galaxy clusters. ....
