It was also associated with a higher risk of anxiety and depression, issues typically more prevalent in women. It allows us to send highly stable laser signals through the atmosphere while retaining the quality of the original signal.". The ratio of index finger length to ring finger length (2D:4D) is an index of prenatal androgen exposure. That said, the new study on spatial cognition and digit ratio by Carl Pintzka—a neuroscientist at the Norwegian University of Science and Technology (NTNU)—adds to a growing body of research that has unearthed various characteristics that are linked to finger length ratios.

Dr. Sascha Schediwy, ICRAR-UWA senior researcher, envisioned numerous applications for their technology, whose precise performance beats even the best optical atomic clocks. Men with longer index fingers were 33% less likely to develop prostate cancer, and men under 60 had an 87% lower risk. As an example, the amount of testosterone in the womb has been associated with an increased risk of developing diseases in adulthood that are more common in men, such as autism and Tourette's syndrome. When the 'finger length index' is larger than 0.96 (which represents the 97th percentile - see picture above) then finger length can safely be described to represent 'extraordinary long fingers'.
