Queen bee development depends on unique wax in royal chambers, not just royal jelly. The wax is softer, less dense, and chemically distinct, improving survival and development.
Oetzi Hosts Living Ancient Yeasts
Researchers find metabolically active, cold-adapted yeasts in Oetzi the Iceman's body. Mohamed Sarhan and colleagues say the microbes may have been present since his death 5,300 years ago.
Common Bean Plants Use Receptor to Detect Caterpillars
Researchers identified a cell-surface receptor in common bean plants that detects caterpillar feeding and triggers anti-herbivore defenses. Adam Steinbrenner’s team confirmed the receptor enables plants to attract predatory wasps during attacks.
New PET Imaging Quantifies Synaptic Loss in MS
Researchers developed a PET imaging method to measure synaptic loss in multiple sclerosis patients' spinal cords. The approach uses SV2A PET to detect reduced synaptic density in both mice and humans with the disease.
