Detecting Asthma
Radiologists developed a new
method for viewing the lungs
of asthma sufferers. The
method uses a polarized
helium-3 gas--making it
visible during an MRI. The
patient inhales the helium-3
and undergoes an MRI, where

Bacteria As Art
Biophysicists are growing
Petri dishes of different
species of bacteria in order
to develop new antibiotics.
The bacteria are subjected
to different temperatures
and have limited food
sources inside the dish.

Diagnosing Heartburn
Gastroenterologists are
using confocal laser
endomicroscopy (CLE) to more
effectively diagnose chronic
heartburn. The technology
gives doctors an image of
the esophagus that is
magnified 1,000 times. A

Sound Detects Breast Cancer
Radiologists suspend a
patient's breast in water,
and then send sound waves
through the water in order
to image breast tissue. The
device uses 256 ultrasonic
sensors to assemble 50 to 70
