A native mosquito in Missouri has fewer parasites when it shares its waters with an interloper, according to new research from biologists at Tyson Research Center, the environmental field station for Washington University in St. Louis.
Tungiasis is a neglected tropical disease caused by penetrated sand fleas which burrow into the skin of the feet. Public health policies such as sealing house and classroom floors and daily feet washing with soap could cut the number of tungiasis cases in school-aged children, researchers now report in PLOS Neglected Tropical Diseases.
Research shows that animals move faster through 'low quality' habitats (fulfilling a minimum of resources for survival) -- evidence that could change the way conservationists think about managing urban landscapes to help species move in response to climate change. In light of the recent UN report indicating that 1 million species are threatened with extinction, the study provides a framework for definitive action to help preserve many species at risk.
A new study publishing May 14, 2019 in the open-access journal PLOS Biology by the Mellone lab at the University of Connecticut and the Larracuente lab at the University of Rochester combine cutting-edge sequencing technology with molecular and high-resolution microscopy methods to discover the sequences of all centromeres in the fruit fly Drosophila melanogaster, a powerful model organism widely used in biomedical research.
Researchers led by Kanazawa University developed a transgenic approach to inactivating the mosquito salivary protein AAPP. Transgenic mosquitoes showed significantly longer probing and prediuresis times, and worse feeding success and meal sizes compared with their wild-type counterparts. Although malarial parasite development was unaffected by these behavioral changes in a laboratory setting, real-world stresses associated with parasite burdens would be expected to adversely affect the survival of transgenic mosquitoes.
Two moth species new to science belonging to a previously unknown genus and family have been found in Kazakhstan, constituting an exceptional discovery.
Rutgers researchers have identified a siesta-suppressing gene in fruit flies, which sheds light on the biology that helps many creatures, including humans, balance the benefits of a good nap against those of getting important activities done during the day.
Feeding mosquitoes sugar makes them less attracted to humans, a response that is regulated by the protein vitellogenin, according to a study publishing May 9 in the open-access journal PLOS Biology by Jessica Dittmer, Paolo Gabrieli and colleagues at the Università degli Studi di Pavia in Italy.
Zoologists in Cologne and Bonn have developed a new method for displaying previously invisible surface details using computer tomography. The key to success was a method from scanning electron microscopy: coating the sample with gold.
A new University of Michigan study provides the first evidence of transitive inference, the ability to use known relationships to infer unknown relationships, in a nonvertebrate animal: the lowly paper wasp.
