A research team led by the University of Notre Dame is working to cut the test time for disease biomarkers. The new timeline-30 minutes instead of 13 hours-uses even smaller sample sizes to offer a new liquid biopsy option.  A new focused ultrasound approach-low-energy, rapid, short-pulsed ultrasound-can open the blood-brain barrier (BBB) using microbubbles and deliver drugs more uniformly and more safely than methods based on long ultrasound pulses.  MIT engineers have designed tiny robots that can help drug-delivery nanoparticles push their way out of the bloodstream and into a tumor or another disease site.  Researchers have shown that existing optical fibre technology could be used to produce microscopic 3-D images of tissue inside the body, paving the way towards 3-D optical biopsies.  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.  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.  Elaborate molecular networks inside living cells enable them to sense and process many signals from the environment to perform desired cellular functions.  RNA sequencing is a technique used to analyze entire genomes by looking at the expression of their genes.  Researchers from the University of Chicago have developed a high-throughput RNA sequencing strategy to study the activity of the gut microbiome.  Today a large international consortium of researchers published a complex but important study looking at how DNA works in animals.  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 ...
