A closer look at how honey bee colonies determine which larvae will serve as workers and which will become queens reveals that a plant chemical, p-coumaric acid, plays a key role in the bees’ developmental fate.
Oysters not only transmit human norovirus; they also serve as a major reservoir for these pathogens, according to newresearch.
Mutants of a common fungus produce endoxylanase enzymes twice as potent as the original strain.
New research examines the experiences of California residents who have been prescribed medical marijuana and the stigma they experience from public opinion. The findings indicate that the stigma of using medical marijuana may contribute to the under-treatment of those who might benefit from medical marijuana.
A new study describes the bio-archaeological remains of the Philistine culture in Israel during the Iron Age (12th century to 7th century BCE). The results of this research indicate that the ca. 600 year presence of the Philistine culture had a major and long-term impact on local floral biodiversity.
A growing, dividing cell uses most of its energy store to make its “protein factories,” the ribosomes. An important player in their “assembly” is the exosome, a molecular shredding machine that breaks down excess ribonucleic acid (RNA). Researchers have discovered how the exosome identifies its target RNA. The team identified a specific detection signal, comparable to a postal code or bar code that targets the exosome to the remote RNA.
A professor who studies birds around the world has discovered trends in how the offspring grow, how parents care for the young and how well the young survive based on where they live.
Scientists can now watch dynamic biological processes with unprecedented clarity in living cells using new imaging techniques. The new methods dramatically improve on the spatial resolution provided by structured illumination microscopy, one of the best imaging methods for seeing inside living cells.
The milkweed plants growing in 40 cube-shaped chambers on a hilltop at the University of Michigan Biological Station provide a glimpse into the future that allows researchers to ask a question: How will monarch butterflies fare?
The dominant matriarchs of meerkat society carry a heavy burden. Not only are these females stressed from having to constantly scold and cajole the rowdy members of the tribe to maintain their perch as the primary breeders and enforcers of the clan, they apparently host more parasites as well.
