(Phys.org)—Epigenetics - the science of how gene activity can be altered without changes in the genetic code - plays a critical role in every aspect of life, from the differentiation of stem cells to the regulation of metabolism ...
For humans to grow and to replace and heal damaged tissues, the body's cells must continually reproduce, a process known as "cell division," by which one cell becomes two, two become four, and so on. A key question of biomedical ...
University of Toronto Faculty of Medicine researchers have uncovered a genetic basis for fundamental differences between humans and other vertebrates that could also help explain why humans are susceptible to diseases not ...
The Supreme Court announced Friday it will decide whether companies can patent human genes, a decision that could reshape medical research in the United States and the fight against diseases like breast and ovarian cancer.
A group of Tasmanian devils will be transferred to a small Australian island to start what is hoped will be a self-sustaining population, free from the facial tumour that has devastated their species.
When someone develops liver cancer, the disease introduces a very subtle difference to their bloodstream, increasing the concentration of a particular molecule by just 10 parts per billion.
(Phys.org)—Spots on the butts of fruit flies are really, really small. But what a researcher and his graduate student are discovering about them could be gigantic.
In their quest for a cancer cure, researchers at the Duke Cancer Institute made a serendipitous discovery—a molecule necessary for cheaper and greener ways to produce nylon.
(Phys.org)—The solution to a biochemical puzzle over the molecular make-up of a coral reef sea sponge (Theonella swinhoei) has revealed the origin of its extremely toxic agents.
Johns Hopkins scientists report what is believed to be the first evidence that complex, reversible behavioral patterns in bees – and presumably other animals – are linked to reversible chemical tags on genes.
