Animals that carry a physical impediment can work harder to rear their young as a result, an insect study has shown. They may behave this way in case they are not able to reproduce again, scientists suggest.
Discovery of why two of the most economically important bee species are immune to one neonicotinoid insecticide but not to others promises to yield chemical treatments that protect crops from pests without harming these essential pollinators, honeybees and bumblebees. Bee pollinators are equipped with biochemical defence systems, in the form of specific enzymes, that define their sensitivity to insecticides by enabling them to metabolise the chemicals safely, report an international team of researchers.
You've probably heard that the safety of neonicotinoid pesticides to bees is a matter of considerable controversy. However, neonicotinoids show varying toxicity to bees. Now, researchers reporting in the journal Current Biology on March 22 have new evidence in honeybees and bumble bees that helps to explain why bees differ in their sensitivity to different neonicotinoids.
Yeasts are tiny fungi -- but they play key roles in producing everything from beer and cheese to industrial chemicals and biofuels. And now scientists are proposing a new approach that could help these industries find new yeasts for use in their manufacturing processes.
Researchers at the University of British Columbia have shed new light on how mountain pine beetles produce an important pheromone called trans-verbenol, which could aid in efforts to better predict outbreaks.
Forget the bows and curtsies. Worker termites shake in the presence of their queens and kings. New research explains how these workers smell a royal presence.
Dr. Stefano Vanin was part of an international team working on discoveries at the Holocene age hunter-gatherer site at Takarkori in south-western Libya.
Defying gravity: A special mixture of proteins in the larval food of bees ensures that future queen larvae survive. Surprisingly this has less to do with nourishment than with gravity. The special properties of the proteins prevent the large and heavy larvae from falling out of their cells. Researchers at Martin Luther University Halle-Wittenberg (MLU) have discovered how this is accomplished at a molecular level. Their study appeared in the internationally renowned journal Current Biology.
After a 100-year flood struck south central Oklahoma in 2015, a study of the insects, arthropods, and other invertebrates in the area revealed striking declines of most invertebrates in the local ecosystem, a result that researchers say illustrates the hidden impacts of natural disasters.
Honeybee larvae develop into queen bees if they are fed large quantities of a food called royal jelly. But royal jelly does more than determine whether a larva becomes a queen: it also keeps her safely anchored to the roof of the queen cell in which she develops. Research published in Current Biology on March 15 explains how the pH of royal jelly helps make the substance viscous enough to keep the queen-to-be from falling.
