In the Galapagos Islands, Darwin's finches drawn to junk food are experiencing changes in their gut microbiota and their body mass as compared to finches that don't encounter human food, according to a new University of Connecticut study.
Mutations in a gene involved in brain development have led to the discovery of two new neurodevelopmental diseases by an international team led by researchers at McGill University and CHU Sainte-Justine Research Center.
In a study published in Cell, a team led by Dr. CHEN Lingling at the Shanghai Institute of Biochemistry and Cell Biology of the Chinese Academy of Sciences (CAS) and Dr. YANG Li at the CAS-MPG Partner Institute for Computational Biology discovered that most examined circRNAs tend to form 16-26 bp intramolecularly imperfect RNA duplexes. In addition, circRNAs preferentially bind to dsRNA-activated protein kinase (PKR) which is related to innate immunity and act as PKR inhibitors.
Songbirds that pack on as much as 50 percent of their body weight before migrating and that sleep very little, exhibit altered immune system and tissue-repair function during the journey, which may hold implications for human health, according to Penn State researchers.
Researchers at Nemours Children's Health System have developed a new low-cost genetic test that accurately identified more than 200 known disease-causing gene variations in two high-risk populations, the Old Order Amish and Old Order Mennonites of Lancaster County, Pennsylvania. The findings, published today in the Journal of Molecular Diagnostics, could help reduce morbidity and mortality from these rare genetic disorders, and dramatically reduce costs of care through early diagnosis of newborns.
Many biomolecules come in two versions that are each other's mirror image, like a left and a right hand. Cells generally use the left-hand version of amino acids to produce proteins, and uptake mechanisms were thought to share this preference. University of Groningen scientists have now shown that a prokaryotic transport protein can transport both versions of the amino acid aspartate with equal efficiency.
Chemical engineers at the University of Pittsburgh Swanson School of Engineering have recreated collaboration and competition responses within a microchamber environment of microscopic particles, sheets, and catalysts, effectively mimicking responses of feeding, fighting, and fleeing.
A new expert panel report from the Council of Canadian Academies (CCA) finds that conventional methods of natural resource management haven't kept pace with the scale and complexity of 21st century problems. It concludes that we know enough to act on integrated approaches to engagement, planning, and decision-making that will protect the health and competitiveness of Canada's resource industries.
The vaccine proves safe in a small sample of human subjects, opening the way for the next phase of testing.
Individualized nutrition not only causes hospital patients to consume more protein and calories, but also improves clinical treatment outcomes. This has been demonstrated in a study by researchers from the University of Basel and Aarau Cantonal Hospital in the journal The Lancet.
