Multi-population risk scores could improve risk prediction for inflammatory bowel diseases, study finds

Using genetic data from nearly 30,000 people, Mount Sinai researchers have built risk scores from a combination of datasets representing distinct ancestral populations that improve prediction of risk for inflammatory bowel diseases (IBD) including Crohn’s disease and ulcerative colitis. The study was published in Gastroenterology on December 24. The researchers found that polygenic risk scores, […]

Unique prediction of ‘modified gravity’ challenges dark matter theory

The best example is represented by the Sunflower galaxy (NGC 5055) with the strongest external fieldamong SPARC galaxies, whose well-measured rotation curve shows a mildly declining behavior at largeradial distance and can be accurately modeled only with an external field effect.

Boosting Weather Prediction with Machine Learning

Today predictions of the next several days’ weather can be remarkably accurate, thanks to decades of development of equations that closely capture atmospheric processes. However, they are not perfect. Data-driven approaches that use machine learning and other artificial intelligence tools to learn from past weather patterns might provide even better forecasts, with lower […]
