Researchers have explored how integrating machine and deep learning techniques can create a standardized system for evaluating rock climbing routes to provide a difficulty grading scale that promotes inclusivity, accuracy and accessibility for all experience levels. The study found that the most successful approach for determining the difficulty of a rock-climbing route used route-centric, natural language processing methods.

Low-density lipoproteins (LDL) -- commonly known as bad cholesterol -- have long been on scientists' radar as a major contributor to heart disease. But these microscopic troublemakers have hidden their inner workings behind a maze of complexity. That is, until now. Researchers have now revealed the specific shape and structure of one of the body's most important yet complicated proteins: ApoB100. Acting as a kind of molecular exoskeleton, this protein wraps around LDL particles, allowing them to travel through the bloodstream, researchers found.

Maternal vitamin D levels in the first trimester were related to both prenatal growth and pregnancy outcomes, according to a new study. Low vitamin D levels during the first trimester of pregnancy were associated with higher rates of preterm birth and decreased fetal length.
