DNA Bonds Dogs and Humans

Authors: George Rajna

Domestic dogs come in all shapes and sizes, but the animals we now regard as man's best friend may have originated from just two populations of wolves, research suggests. [31] In a recent study in mice, researchers found a way to deliver specific drugs to parts of the body that are exceptionally difficult to access. [30] Now MIT engineers have come up with a tissueengineering design that may enable flexible range of motion in injured tendons and muscles during healing. [29] Researchers at MIT, working with surgeons and oncologists at Massachusetts General Hospital (MGH), have now developed a way to improve the accuracy of this surgery, called debulking. [28] Scientists at the University of Bristol have invented a new technology that could lead to the development of a new generation of smart surgical glues and dressings for chronic wounds. [27] Elaborate molecular networks inside living cells enable them to sense and process many signals from the environment to perform desired cellular functions. [26] RNA sequencing is a technique used to analyze entire genomes by looking at the expression of their genes. [25] Researchers from the University of Chicago have developed a high-throughput RNA sequencing strategy to study the activity of the gut microbiome. [24] Today a large international consortium of researchers published a complex but important study looking at how DNA works in animals. [23] Asymmetry plays a major role in biology at every scale: think of DNA spirals, the fact that the human heart is positioned on the left, our preference to use our left or right hand ... [22] Scientists reveal how a 'molecular machine' in bacterial cells prevents fatal DNA twisting, which could be crucial in the development of new antibiotic treatments. [21]
