SUTD and collaborators developed novel methodology to predict spinal fractures in patients

A new computational clinical tool predicts osteoporotic vertebral fractures by analyzing patient-specific finite element analysis of functional spinal units from routine clinical scans. The method enables more accurate patient-specific analysis, paving the way for a spinal risk assessment tool and targeted early treatment strategies.

Augmenting attention treatment therapies for difficult-to-treat anxiety in children and adolescents

A new study published in the Journal of the American Academy of Child and Adolescent Psychiatry found that computer-based attention training reduced anxiety in 50% of participants. The treatment involved targeting neutral or threatening stimuli, leading to comparable reductions in anxiety. This promising result provides a potential aug...

Why your first battle with flu matters most

Research finds that exposure to one subtype of flu virus in childhood can grant extra protection against future infections, but not if the second strain is from a different group. This explains why some people fare better than others when infected with the same strain.
