UCLA Researchers Identify Peptide That Inhibits Replication of Hepatitis C Virus

Researchers from UCLA’s Jonsson Comprehensive Cancer Center have identified a cell-permeable peptide that inhibits a hepatitis C virus protein and blocks the viral replication that can lead to liver cancer and cirrhosis.

The finding by Dr. Samuel French, a UCLA assistant professor of pathology and senior author of the research, builds on previous work by French’s laboratory that identified two cellular proteins that are important factors in hepatitis C virus infection. (more…)

Americans Overestimate Political Polarization, According To New CU-Boulder Research

Many Americans overestimate the degree of polarization between Democrats and Republicans, and this misconception is associated with citizens’ voting behavior and their involvement in political activities, according to new findings from the University of Colorado Boulder.

“It is clear that Americans see themselves as very sharply polarized,” said Professor Leaf Van Boven, who led the research efforts. “And that the extent of perceived polarization dramatically overstates the actual degree of polarization.” (more…)

A Bug’s (Sex) Life: Diving Beetles Offer Clues About Sexual Selection

*Studies of diving beetles suggest sperm evolution may be driven by changes in female reproductive organs, challenging the paradigm of post-mating sexual selection being driven mostly by competition among sperm.*

Studying female reproductive tracts and sperm in diving beetles (Dytiscidae), researchers from the University of Arizona and Syracuse University have obtained a glimpse into a bizarre and amazing world of sperm that can take on a variety of forms – including joining together into conglomerates that navigate the twisted mazes of the female reproductive tract.

Analyses of the evolutionary relationships among diving beetles reveal that sperm form appears to follow function dictated by female reproductive organs. (more…)
