While making smart glue, a team of engineers discovered a handy byproduct: hydrogen peroxide. In microgel form, it reduces bacteria and virus ability to infect by at least 99.9 percent.
Male salmon are maturing earlier and becoming smaller, and it shows in their genes. This was the discovery of a study that examined scale samples from salmon over a 40-year period, and looked at the population genetic profile of a gene that determines salmon's age of maturity and size. The results show that the 'big salmon gene version' has become rarer in the population over time, and has been replaced by the 'small salmon gene version'.
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.
The researchers explored the efficacy of a multi-therapy approach based on the disease risk factor status specific to individuals with Alzheimer's disease (AD) diagnosis or concern. The findings indicate previously unidentified connectivity between AD risk factors, suggesting that treatment regimens should be tailored to the individual and multi-modal to simultaneously return several risk factors to a normative state.
A team of researchers in France and at MIT has taken the first three-dimensional images of kerogen's internal structure, with a level of detail more than 50 times greater than has been previously achieved. The images should allow more accurate predictions of how much oil or gas can be recovered from any given formation.
Around the world, 425 million people live with diabetes and upwards of 15 percent develop foot ulcers, which increases their risk of death 2.5 times. A new nitric oxide-releasing technology has the potential to cut down the healing time of diabetic foot ulcers from 120 days to 21 days.
Indiana University scientists paired drug-delivering nanoparticles like dance partners to reveal that molecules attach to targets on cells differently based upon their position in time. The discovery could improve methods for screening drugs for therapeutic effectiveness.
Machine learning is increasing the pace of development of customised carbon surfaces with a wide variety of applications
Neuronal development is often regulated by the graded distribution of guidance molecules, but many details about the process is largely unexplored. A research team from City University of Hong Kong (CityU) has tackled this problem in a precise and systematic way by developing a novel device, and has published their findings in the latest issue of Nature Communications.
Computer scientists at Carnegie Mellon University say neural networks and supervised machine learning techniques can efficiently characterize cells that have been studied using single cell RNA-sequencing (scRNA-seq). This finding, published in the online journal Nature Communications, could help researchers identify new cell subtypes and differentiate between healthy and diseased cells.
