3-D mammography: More breast cancers detected

A pilot trial of 3-D mammography—tomosynthesis—has shown that breast cancer detection, recall for assessment, and screen reading time were each higher than for standard mammography, but it is too soon to tell if more detection leads to better health outcomes for women, according to the authors of research published today in the Medical Journal of […]

Scientists create brain-mimicking environment to grow 3-D tissue models of brain tumors

A team of Tufts University-led researchers has developed three-dimensional (3-D) human tissue culture models of pediatric and adult brain cancers in a brain-mimicking microenvironment, a significant advancement for the study of brain tumor biology and pharmacological response. The study was published today in Nature Communications. The researchers created models that include brain-derived extracellular matrix (ECM) […]

Going the distance: Brain cells for 3-D vision discovered

In stunning images captured under the microscope for the first time, the neurons were found in praying mantises. The work is published in Nature Communications today. In a specially-designed insect cinema, the mantises were fitted with 3-D glasses and shown 3-D movies of simulated bugs while their brain activity was monitored. When the image of […]

Satiety in 3-D

Many overweight people lack the feeling of being full. It was long thought that this was due to the disrupted transport of the satiety hormone leptin to the brain. That is not the case, as a group of scientists from Helmholtz Zentrum München has now shown in the International Journal of Obesity. The work was […]
