A new federally funded study led by Brown University biologists and scientists at Yellowstone National Park revealed that different circumstances lead herbivores to eat a much wider variety of plants than previously believed.

Published in the Proceedings of the National Academy of Sciences, the new research suggests that the traditional classification schemes that distinguish herbivores by their percent of grass consumption are oversimplifications that can fail to reflect dietary variation within and across species, said study co-author Tyler Kartzinel, an associate professor of ecology, evolution and organismal biology at Brown.

A team of researchers, including several from UC San Diego, have shown, through theoretical calculations, how collapsing massive stars can act as a "neutrino collider,” which may result in either a neutron star remnant or black hole remnant, depending on the “flavor” of the neutrinos.

A new study led by FAMU-FSU College of Engineering researchers investigating precision polymer blends revealed critical insights that could accelerate the development of advanced materials for batteries, membranes and energy storage systems.

The research, which focused on blends of a polymer called polyethylene oxide (PEO) and a charged polymer known as p5, found that even small amounts of charge can dramatically alter how these materials mix. This behavior aligns with previously developed theoretical models, offering a new framework for anticipating when polymer blends will remain uniform or separate into distinct phases.

Johns Hopkins University researchers have identified more than 200 types of misfolded proteins in rats that could be associated with age-related cognitive decline. The findings could lead the way to finding new therapeutic targets and treatments in humans that could provide relief for the millions of people over 65 who suffer from Alzheimer’s, dementia, or other diseases that rob them of their memories and independence as they age.
