Research published in Nature reveals insights into how the body maintains balance with "good" gut bacteria that allows these microbes to flourish in the intestine but keeps them out of tissues and organs where they're not supposed to be.
Brown bears that are more inclined to grate and rub against trees have more offspring and more mates, according to a University of Alberta study. The results suggest there might be a fitness component to the poorly understood behaviour.
A study published in the journal Scientific Reports reveals the genetic structure of the land snail Xerocrassa montserratensis and it provides new scientific tools for the improvement of the conservation of this endemic and threatened species in Catalonia.
Researchers from the £12 million Developing Human Connectome Project have used the dramatic advances in medical imaging the project has provided to visualise and study white matter pathways, the wiring that connects developing brain networks, in the human brain as it develops in the womb.
In previously unstudied gopher tortoise aggregations, researchers found that overall, 42.9 percent had circulating antibodies to an infectious bacterium that causes upper respiratory tract disease. Physical examination showed that 19.8 percent had clinical signs consistent with upper respiratory tract disease and 13.2 percent had some form of physical abnormality. None of the tortoises tested positive for Ranavirus or Herpesvirus, which represents important baseline data, since these viruses are thought to be emerging pathogens of other tortoise and turtle species.
Like an airplane's black box, a woman's placenta can show if something went wrong during pregnancy. A new Northwestern Medicine study of 84 vaccinated patients and 116 control patients found the COVID-19 vaccine did not damage the placenta during pregnancy.
New research which shows that fasting diets could harm the health of future generations. Fasting diets have risen in popularity in recent years, however little is known about the long-term impact of these diets, particularly for future generations. The new study reveals that reduced food intake in roundworms has a detrimental effect on three generations of offspring - particularly when those descendants have access to unlimited food.
Surprising findings can help improve organoid cultures, explain role of GSK3-beta in brain development
Scientists have developed a novel genetic sensor called a "CopyCatcher," which capitalizes on CRISPR-based gene drive technology, to detect instances in which a genetic element is copied precisely from one chromosome to another throughout cells in the body of a fruit fly. Next-generation CopyCatcher systems have the potential to measure how often such perfect copying might take place in different cells of the human body.
For the first time, researchers at Penn Medicine created organoids of the arcuate nucleus (ARC),providing an atlas of cell types in the human hypothalamus, which will be a blueprint to further understanding the development of brain disorders, such as certain causes of obesity and autism.
