Symbiotic bacteria protect hunting wasps from fungal infestation
...eptomyces bacteria in unique structures within its antennae
and that females utilize these bacterial symbionts...this process, the researchers show, they use their antennae
to deliver the symbiotic bacteria to the ceiling of the brood cell before finally closing off the ce...
Fighting malaria by manipulating mosquitoes' sense of smell
...t strongly with receptors in the female mosquito's antennae
and appear to be related to host selection. The most promising of these mixtures will be shipped to Wageningen University where their effects on the behavior of live mosquitoes will be determined. Compounds that pass the behavioral tests will be forw...
Female butterflies go for sparkle -- not size -- when choosing to mate
...his wings is two-fold: to spread pheromones to her antennae
and to stimulate her visually. The female appears to be very sensitive to this rapid flickering, which probably looks to her like a strobe-light effect." Robertson added that while these conclusions are applicable only to this particular species of ...
Common bacteria pirate natural mechanism to get inside cells
...receptor signaling, likens receptors to television antennae
that control relay of signals from outside the cell to inside by turning on or off. Although there are no known receptors that have the job of triggering a bad result in the body, receptors that are 'on' too much may end up instructing the cell to do...
How low can you go? Ants learn to limbo
... was made invisible to them, they had to use their antennae
to examine it". The researchers motivated the ants to run back and forth by placing biscuit crumbs flavoured with melon and tuna at one end of a channel. They observed the ants' reaction towards a horizontal barrier placed between the food and the a...
Can you hear me now? Scientists find previously unknown receptors on adult stem cells
...discovered is that these stem cells have a sort of antennae
that detect bacteria and viruses," continued the OMRF researcher. "And when stem cells receive these distress signals, they spring to action, creating cells the body most needs early in life-threatening situations." This messaging system normally se...
How ants find their way
...ay of travelling as the ant needs to walk with its antennae
to the ground. However, this initial route forms the basis of an efficient learning strategy. On the first trip ants store images of the route as they travel and on later trips to the food site will navigate using a combination of landmarks and memor...
Hives ferment a yeasty brew, attract beetle pest
...trance to an undisturbed honeybee colony, but, the antennae
of guard and forager bees did not detect this level of IPA. "This indicates strongly that the heightened sensitivity of the beetles to volatiles released from the hive entrance allows them to key in on the bee colonies without bees responding to t...
