Electric ‘Smart’ Paper Picks Up on Pipe Leaks

Although spills inside a lab can often spell trouble, a University of Washington scientist found a way to turn an accidentally doused conductive material into an inventive new sensor. The lab mishap led to a “smart” paper that conducts electricity and provides wireless detection of water pipe leaks.

A Semiconductor Breakthrough: Carbon Nanotubes Boost Thermoelectric Performance

In a report published in October, scientists from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) used single-walled carbon nanotubes (SWNCTs) to advance the thermoelectric performance of organic semiconductors. The carbon nanotube thin films, they said, could ultimately be integrated into fabrics to convert waste heat into electricity or serve as a small power source.

Unique Imaging of Dinosaur's Skull Tells Evolutionary Tale

Researchers using Los Alamos' unique neutron-imaging and high-energy X-ray capabilities have exposed the inner structures of the fossil skull of a 74-million-year-old tyrannosauroid dinosaur nicknamed the Bisti Beast in the highest-resolution scan of tyrannosaur skull ever done. The results add a new piece to the puzzle of how these bone-crushing top predators evolved over millions of years.

New Dental Imaging Method Uses Squid Ink to Fish for Gum Disease

Squid ink might be a great ingredient to make black pasta, but it could also one day make getting checked for gum disease at the dentist less tedious and even painless. By combining squid ink with light and ultrasound, a team led by engineers at the University of California San Diego has developed a new dental imaging method to examine a patient's gums that is non-invasive, more comprehensive, and more accurate than the state of the art.
