Magnetic nanotags spot cancer in mice earlier than methods now in clinical use

Researchers at Stanford University developed a new magnetic-nano sensor chip that can detect cancer-associated proteins with high accuracy and search for up to 64 different proteins simultaneously. The sensor is up to 1,000 times more sensitive than current methods and can detect biomarkers in bodily fluids with low concentrations.

More infants surviving pre-term births results in higher rates of eye problems

A Swedish study found that more pre-term infants surviving in neonatal intensive care units are experiencing vision problems due to retinopathy of prematurity, a condition involving abnormal blood vessel development in the retina. The incidence of this condition is higher in extremely preterm infants born before 27 weeks' gestation.

A high fat diet during pregnancy can lead to severe liver disease in offspring

Researchers at the University of Southampton discovered a link between a mother's high-fat diet during pregnancy and her child's development of fatty liver disease. The study found that a high-fat diet can affect the developing liver of a fetus, making it more susceptible to fatty liver disease later in life.
