(Medical University of South Carolina) Medical University of South Carolina neuroscientists have identified a region of brain that may be a new clinical target to treat addiction. In a Translational Psychiatry article, they report locating a 'hot spot' in brain activity associated with substance use disorder that could potentially be targeted by brain stimulation therapies such as transcranial magnetic stimulation (TMS). These findings have led to a clinical trial of TMS in patients with cocaine and alcohol use disorder.

(Nanyang Technological University) NTU Singapore scientists have developed a 'contact lens' patch with microneedles that could be a painless and efficient alternative to current methods of treating eye diseases such as glaucoma. Patients are unable to keep up with the prescribed regime of current localised treatment methods like eye drops, which are hindered by the eye's natural defences, blinking and tears. Eye injections can be painful and carry an infection risk and eye damage.

(Medical Research Council) Scientists have equipped a virus that kills carcinoma cells with a protein so it can also target and kill adjacent cells that are tricked into shielding the cancer from the immune system. It is the first time that cancer-associated fibroblasts within solid tumors -- healthy cells that are tricked into protecting the cancer from the immune system and supplying it with growth factors and nutrients -- have been specifically targeted in this way.

(University of California - Berkeley) A single season of high school football may cause microscopic changes in the structure of the brain, according to a new study by researchers at the University of California, Berkeley, Duke University and the University of North Carolina at Chapel Hill. A new type of magnetic resonance imaging (MRI) revealed significant changes in the structure of the grey matter in the front and rear of the brain and changes to structures deep inside the brain.

(Rice University) A 'smart skin' developed at Rice University employs the unique fluorescent characteristics of carbon nanotubes to quickly assess strain in materials. The method is intended for aircraft, spacecraft and critical infrastructures in which mechanical strain needs to be monitored.

(NIH/National Eye Institute) By combining two imaging modalities -- adaptive optics and angiography -- investigators at the National Eye Institute (NEI) can see live neurons, epithelial cells, and blood vessels deep in the eye's light-sensing retina. Resolving these tissues and cells in the outermost region of the retina in such unprecedented detail promises to transform the detection and treatment of diseases such as age-related macular degeneration (AMD), a leading cause of blindness among the elderly.

(University of Arizona College of Engineering) By developing stronger and more stable phase change material -- the stuff that holds the data stored on microchips and rewritable CDs -- researcher Pierre Lucas brings us closer to a reality where data storage systems operate like artificial neural networks.
