Mystery of the missing mercury at the Great Salt Lake

April 24, 2017

Around 2010, the deep waters of Utah’s Great Salt Lake contained high levels of toxic methylmercury. Mercury measurements in waterfowl surrounding the lake led to a rare human consumption advisory for ducks. But by 2015, 90 percent of the deep mercury was gone. The disappearance of the mercury was not due to aggressive environmental policies […]



How nature engineered the original rotary motor

April 17, 2017

The bacterial flagellum is one of nature’s smallest motors, rotating at up to 60,000 revolutions per minute. To function properly and propel the bacterium, the flagellum requires all of its components to fit together to exacting measurements. In a study published today in Science, University of Utah researchers report the eludication of a mechanism that […]



A badger can bury a cow by itself

March 29, 2017

While studying scavenger behavior in Utah’s Great Basin Desert, University of Utah biologists observed an American badger do something that no other scientists had documented before: bury an entire calf carcass by itself. Watch a video of the badger here. While badgers and their relatives are known to cache food stores, this is the first […]



How seawater strengthens ancient Roman concrete

February 24, 2017

Around A.D. 79, Roman author Pliny the Elder wrote in his Naturalis Historia that concrete structures in harbors, exposed to the constant assault of the saltwater waves, become “a single stone mass, impregnable to the waves and every day stronger.” He wasn’t exaggerating. While modern marine concrete structures crumble within decades, 2,000-year-old Roman piers and […]



Stabilizing energy storage

February 21, 2017

Because the sun doesn’t always shine, solar utilities need a way to store extra charge for a rainy day. The same goes for wind power facilities, since the wind doesn’t always blow. To take full advantage of renewable energy, electrical grids need large batteries that can store the power coming from wind and solar installations […]



“Field patterns” as a new mathematical object

February 13, 2017

University of Utah mathematicians propose a theoretical framework to understand how waves and other disturbances move through materials in conditions that vary in both space and time. The theory, called “field patterns,” published today in Proceedings of the Royal Society A. Field patterns are characteristic patterns of how disturbances react to changing conditions. Because field […]



Flat-footed fighters

February 8, 2017

Walking on our heels, a feature that separates great apes, including humans, from other primates, confers advantages in fighting, according to a new University of Utah study published Feb. 15 in Biology Open. Although moving from the balls of the feet is important for quickness, standing with heels planted allows more swinging force, according to study […]



Flipping the switch on ammonia production

February 3, 2017

Nearly a century ago, German chemist Fritz Haber won the Nobel Prize in Chemistry for a process to generate ammonia from hydrogen and nitrogen gases. The process, still in use today, ushered in a revolution in agriculture, but now consumes around one percent of the world’s energy to achieve the high pressures and temperatures that […]



Arctic melt ponds form when meltwater clogs ice pores

January 18, 2017

When spring comes to the Arctic, the breakup of the cold winter ice sheets starts at the surface with the formation of melt ponds. These pools of melted snow and ice darken the surface of the ice, increasing the amount of solar energy the ice sheet absorbs and accelerating melt. A team including University of […]



U students to present research on Capitol Hill

January 18, 2017

Jan. 24, 2017— Undergraduate students at the University of Utah and Utah State University will showcase their research for Utah lawmakers on Tuesday, Jan. 24 from 8 a.m. to 1 p.m. in the rotunda of the Utah State Capitol. Research on Capitol Hill, now in its 17th year, gives lawmakers and the public a glimpse […]
