Polygenic scores (PGS) are metrics used to estimate the genetic predisposition of people to developing specific mental health conditions, personality traits or diseases. In recent years, these metrics have often been used to investigate the intricate connections between genes and environmental factors. Researchers recently carried out a study aimed at determining whether neuropsychiatric polygenic scores could predict the professional categories that individuals belong to. Their findings suggest that these scores weakly predict the professional category that people belong to. Specifically, they wished to determine whether PGS scores hinting at a predisposition for specific neuropsychiatric disorders, such as autism spectrum disorder...

SPL Dutch researchers have questioned the effectiveness of a technique that many fertility specialists believe improves the chances of pregnancy. Preimplantation genetic screening (PGS) harms the chances of motherhood for women older than 35, they claim. PGS involves removing a single cell from a three-day-old embryo and checking that a selection of chromosomes is normal. The technique is widely regarded as giving the best chance of success for...
