  The pigment that gives spinach and other plants their verdant colour may improve doctors' ability to examine the human gastrointestinal tract. That's according to a study, published in the journal Advanced Materials, which describes how chlorophyll-based nanoparticles suspended in liquid are an effective imaging agent for the gut.

A temporary "electronic tattoo" developed by Tel Aviv University that can measure the activity of muscle and nerve cells researchers is poised to revolutionise medicine, rehabilitation, and even business and marketing research. The tattoo consists of a carbon electrode, an adhesive surface that attaches to the skin, and a nanotechnology-based conductive polymer coating that enhances the electrode's performance. It records a strong, steady signal ...

  Experiments conducted under the leadership of a Stanford University School of Medicine investigator have succeeded, for the first time, in restoring multiple key aspects of vision in mammals.

A "nano scalpel" enables scientists at DESY to prepare samples or materials with nanometre precision while following the process with a scanning electron microscope. The Focused Ion Beam, or FIB, microscope which has now gone into service also allows a detailed view of the inner structure of materials. The device was purchased by the University of Bayreuth, as part of a joint research project on the DESY campus funded by the Federal Ministry of R...

Cancer Research UK scientists have used imaging techniques as a way to identify patients who could benefit from certain breast cancer treatments, according to a study published in Oncotarget. The team at King's College London, in collaboration with scientists at the CRUK/MRC Oxford Institute for Radiation Oncology, used fluorescence lifetime imaging to confirm if they have joined together.

A team of researchers from Boise State University, led by Eric Krueger and David Estrada, have published an article in the American Chemical Society's Biomaterials Science and Engineering journal. Titled "Graphene Foam as a 3D Platform for Myotube Growth," it focuses on a study demonstrating the suitability of graphene foam as a scaffold for growing functional muscle tissue. Graphene foam is an emerging 3D version of graphene, a layer of carbon s...

Clusters of circulating cells commonly found in the blood of cancer patients have long been the subject of research on cancer. These clusters have been regarded for more than 50 years as malignant cells that have broken off from the primary tumour, spreading cancer to other parts of the body. 

Human diseases are network diseases," said Eyleen O'Rourke, an assistant professor of biology and cell biology at the University of Virginia. By that she means that our genes, cells, tissues and organs all interact and affect each other as a highly complex network of entities that, in combination with the environment – defined as our diet, health habits and other factors – determine whether our bodies are affected by disease, and how ...

Providing a 1500VAC input/output isolation at a 250VAC working voltage to facilitate a 1 x MOPP, XP Power has announced the IMM series of 1 and 2W DC/DC converters. The IMM01 1W and the IMM02 2W single and dual output converters are approved to the international medical safety standards ANSI/AMII ES60601-1, CSA 22.2 No 60601-1 and EN/IEC60601-1.

Drexel University researchers have developed a computer game and smartphone app to help people control unhealthy eating habits and ultimately lose weight. The game is designed to improve a person's "inhibitory control," the part of the brain that stops you from giving into unhealthy cravings—even when the smell of French fries is practically begging you to step inside a fast food restaurant.
