A new study published this week found that the social lives of sweat bees -- named for their attraction to perspiration -- are linked to patterns of activity in specific genes, including ones linked to autism.
To be able to reproduce and become effective disease carriers, mosquitoes must first attain optimal body size and nutritional status. A pair of researchers at the University of California, Riverside, have succeeded in using CRISPR-Cas9, a powerful tool for altering DNA sequences and modifying gene function, to decrease mosquito body size, moving the research one step closer to eliminating mosquitoes that carry dengue fever and Zika virus.
The female of a sex-role reversed cave insect species Neotrogla has evolved a switching valve to receive more semen during mating, when a penis-like structure in the female anchors in the male 'vagina.'
As the prevalence of maternal and fetal complications increases with advancing pregnancy beyond 39 weeks, induction of labor at 39 weeks has been proposed as a means to ensure optimal maternal and newborn health.
Investigators from St. Jude Children's Research Hospital will present new findings at the American Society of Human Genetics annual meeting this week, including study results focused on the benefit of utilizing whole genome, exome and transcriptome sequencing for pediatric cancer patients.
Like people, blue crabs aren't all the same sizes and shapes. Now Rutgers scientists have discovered substantial differences in the body structures of larval crab siblings and among larvae from different mothers. And that can mean the difference between an early death and survival into adulthood for this important commercial and recreational species.
Early results from a first-of-its-kind study by researchers from the Institute for Reproductive Health at Georgetown University Medical Center suggests that typical use of a certain family planning app is as effective as other modern methods for avoiding an unplanned pregnancy.
Cesarean-born mice show altered patterns of cell death across the brain, exhibiting greater nerve cell death than vaginally delivered mice in at least one brain area, a finding by Georgia State University researchers that suggests birth mode may have acute effects on human neurodevelopment that may lead to long-lasting changes in the brain and behavior.
Selfish genes are genes that are passed on to the next generation but confer no advantage on the individual as a whole, and may sometimes be harmful. Researchers at Uppsala University have, for the first time, sequenced (or charted) two selfish genes in the fungus Neurospora intermedia that cause fungal spores to kill their siblings. Unexpectedly, the genes were not related to each other, perhaps indicating that selfish genes are more common than previously thought.
Researchers mapped the postnatal changes in mouse myocardium on three omics levels and multiple time points, highlighting the importance of metabolic pathways as potential drug targets.
