The key to breeding disease-resistant honeybees could lie in a group of genes - known for controlling hygienic behaviour - that enable colonies to limit the spread of harmful mites and bacteria, according to genomics research conducted at York University.
Despite widespread infection, some frog populations are surviving a deadly disease that is the equivalent of mankind's Ebola virus. The reason --genetic diversity.
Stress is known as the "killer disease" and in humans it can lead to an increased risk of terminal issues such as heart attack or stroke. But now research conducted at The University of Texas at San Antonio (UTSA) and published in the latest issue of Plantsindicates that stress in the plant kingdom is far less destructive to plants than it is to humans.
The neural 'time windows' in certain small brain areas contribute to the complex cognitive symptoms of autism, new research suggests. In a brain imaging study of adults, the severity of autistic symptoms was linked to how long these brain areas stored information. The differences in neural timescales may underlie features of autism like hypersensitivity and could be useful as a future diagnostic tool.
The new genus is found exclusively in the recently recognized Seasonally Dry Tropical Forests biome
It is everywhere - and it is extremely dangerous for people with a weakened immune system. The fungus Aspergillus fumigatus occurs virtually everywhere on Earth, as a dark grey, wrinkled cushion on damp walls or in microscopically small spores that blow through the air and cling to wallpaper, mattresses and floors.
In their study, Carolin Sommer-Trembo, Konrad Lipkowski and their two colleagues compare the behaviour of Gammarus males from two populations with very different densities. They collected test animals from two neighbouring areas and let them acclimate for a few days in large aquariums. During this time, pairs formed, with the males firmly grasping the female and not letting her go before fertilization (amplectant pair).
Folliculin gene defects are implicated in some forms of infertility, certain cancers and other cell growth disorders
HIV and SIV infect and kill immune cells called CD4 T cells, a process that ultimately leads to AIDS.
Medicine was transformed in the 20th century by the discovery and development of antibiotics, the vast majority of which came from one source: soil bacteria.
In a context of overuse of insecticides, which leads to the selection of resistant mosquitoes, it is already known that this resistance to insecticides affects interactions between mosquitoes and the pathogens they transmit. Researchers from the Institut Pasteur (Paris) and its partners prove that mechanisms of insecticide resistance, observed in Culex quinquefasciatusvector, impact the transmission of West Nile virus.
Genetic analysis of sticklebacks shows that isolated populations in similar environments develop in comparable ways. The basis for this is already present in the genome of their genetic ancestors. Evolutionary biologists from the University of Basel and the University of Nottingham report these insights in the journal Evolution Letters.
Researchers at the University of Sydney have found that the relationship between the tissue-sucking Varroa mite and virulence of a virus of honey bees, has most likely been misunderstood.
New genomic data from 5 birds-of-paradise reveal genes that are shaped by selection and help explain the origin of their spectacular plumage
To be listed as UNESCO World Heritagerequires special care and protection of valuable cultural monuments and pieces of Art from threats such as biodeterioration caused by microcolonial black fungi.
