Diagnosing obesity by mathematically estimating abdominal fat

Tue, 06/20/2017 - 13:32
Abdominal obesity, or fat that accumulates around one's stomach and abdomen, has long been considered to pose a high health risk in individuals. Hence, measurement of abdominal fat helps predict propensity to disorders caused by excess weight in the abdominal area. In a new paper, researchers propose a new technique to evaluate abdominal obesity by estimating the thickness of subcutaneous fat.

Enhanced photocatalytic activity by Cu2O nanoparticles integrated H2Ti3O7 nanotubes

Tue, 06/20/2017 - 13:31
Compositing Cu2O nanoparticles with H2Ti3O7 nanotubes provides an effective strategy to reduce the bandgap energy and the recombination of photo-generated electrons and holes. There is an obvious synergistic effect between guest nanoparticles and host nanotubes due to the interaction to form heterojunction struction, which will enhance photocatalytic oxidation performance for removal of EM due to the stronger visible spectral response and wider absorbance in the long visble light region.

Figuring out the 3-D shape of molecules with a push of a button

Mon, 06/19/2017 - 16:58

Building a better alligator: Advanced 3-D models of bite data

Fri, 06/16/2017 - 17:56
The ability to bite hard is critical for crocodilians to eat their food such as turtles, wildebeest and other large prey; therefore, their anatomy is closely studied by veterinarians and paleontologists who are interested in animal movements and anatomy. Now, researchers have developed three-dimensional models of the skull of the American alligator using cutting-edge imaging and computational tools.
