Researchers report that the injectable hormone tesamorelin reduces liver fat and prevents liver fibrosis (scarring) in people living with HIV.

Scientists have created a new layered superconducting material with a conducting layer made of bismuth, silver, tin, sulfur and selenium. The conducting layer features four distinct sublayers; by introducing more elements, they were able to achieve unparalleled customizability and a higher ''critical temperature'' below which superconductivity is observed, a key objective of superconductor research. Their design strategy may be applied to engineer new and improved superconducting materials.

Researchers in Australia used a driving simulator to test patients' vision before and after cataract surgery. They found that near misses and crashes decreased by 48% after surgery.

A drug widely prescribed for a bladder condition for decades, now appears to be toxic to the retina, the light sensing tissue at the back of the eye that allows us to see.

New research integrates nanomaterials into heterostructures, an important step toward creating nanoelectronics.

Hydrologic models that simulate and predict water flow are used to estimate how natural systems respond to different scenarios such as changes in climate, land use, and soil management. The output from these models can inform policy and regulatory decisions regarding water and land management practices. Numerical models have become increasingly easy to employ with advances in computer technology and software with graphical user interface (GUI). While these technologies make the models more accessible, problems can arise if they are used by inexperienced modelers.
