Researchers find microplastics in hedgehogs—then trace them back to pet food
Researchers find microplastics in hedgehogs—then trace them back to pet food
When colleagues and I found microplastics in hedgehog droppings, we wanted to know where they were coming from. One answer was surprisingly close to home: pet food.

Discovery of how cells maintain their DNA could shield key healthy cells from chemotherapy
A new study conducted by scientists at the University of Sheffield in collaboration with researchers from UT Southwestern Medical Center in the U.S. has found a protein that could help guide which cells chemotherapies target. The findings, published in Molecular Cell, open up a p
New energy-boosting quantum mechanism discovered in photosynthetic bacteria
Researchers have discovered how certain photosynthetic bacteria use a sophisticated quantum mechanism to increase their efficiency when capturing sunlight. The study, published today in the journal Nature Chemistry and led by Professor Jenny Clark, reveals that nature has been us

How sperm whale vocal dialects evolve as they adopt new calls while still remembering the
New research from the University of St. Andrews shows how sperm whale vocal dialects evolve as they adopt new calls while still remembering the old. An international team of researchers studying vocal dialects in the endangered population of sperm whales that live in the Mediterr

Simple acknowledgment boosts repeat customer participation in take-back programs
Companies may only need to send an acknowledgment message to boost repeat customer participation in recycling and reuse programs for used goods like laptops and coffee pods, according to a new study led by Penn State researchers. The idea for the study arose over a cup of coffee—
