Shen implanted a transparent window made of tough borosilicate glass into the skin over the stomachs of mice. With no skull or bone structures to anchor the window, he needed to devise a 3D-printed surgical insert for stabilization. The device prevents the intestines from moving too much while maintaining normal digestive functions, allowing researchers to look at the same spot over multiple days.
Investigators previously found that mass spectrometer operators in the same lab violated standards between 1996 and Investigators said the operators were making excessive adjustments in instrument readings to compensate for calibration problems.
