Scientists at the Institute of Genetics and Developmental Biology found that only eating high levels of dietary fat makes you fat. They have performed the largest study of its kind to resolve what components of the diet cause mice to put on body fat.
Researchers accidentally observed tree shrews directly and actively consuming chili peppers, despite the deep geographic isolation between the animal and the food. To understand this tolerance for spicy food, they performed genomic and functional analyses on the tree shrew and its TRPV1.
Research in mice shows that a pharmacological strategy can alleviate multiple behavioral and cellular deficiencies in a mouse model of fragile X syndrome, the most common inherited form of intellectual disability.
Genetic research at has shed new light on how isolated populations of the same species evolve toward reproductive incompatibility and thus become separate species.
Researchers using long-read DNA sequencing have made one of the most detailed maps ever of structural variations in a cancer cell's genome. The map reveals about 20,000 structural variations, few of which have been noted before, in just one cell type associated with one form of breast cancer.
Rocky Mountain National Park provides habitat for not one, but two subspecies of the American pika.
Researchers show that mice lacking the Maged1 gene are unable to acquire cocaine addiction. This gene serves as a promising new entry point into the analysis of the mechanisms underlying drug addiction.
University of Kansas scientists discovered that polyps have no qualms about treating a nonrelated individual like part of the family. This goes way beyond sharing meals or even a roof. Polyps of the marine hydrozoan Ectopleura larynx allow nonrelated individuals to fuse their bodies to the familial colony and share what is essentially skin and a stomach. The findings appeared yesterday in the journal Evolution Letters.
An interdisciplinary team of scientists at the Centre for Genomic Regulation in Barcelona, Spain, deepens understanding of tumor genome evolution and suggests negative selection acting on cancer-essential genes plays a more important role than previously anticipated. Their work, published in Genome Biology, also provides new insights for improving cancer immunotherapies in the future.
The sex of a baby controls the level of small molecules known as metabolites in the pregnant mother's blood, which may explain why risks of some diseases in pregnancy vary depending whether the mother is carrying a boy or a girl, according to new research from the University of Cambridge.
