More power to you

July 26, 2016

Engineers from the University of Utah and the University of Minnesota have discovered that interfacing two particular oxide-based materials makes them highly conductive, a boon for future electronics that could result in much more power-efficient laptops, electric cars and home appliances that also don’t need cumbersome power supplies. Their findings were published this month in […]

Farming without soil

July 25, 2016

For the last 10 weeks, University of Utah student Georgie Corkery has investigated sustainable urban farming options for Salt Lake, and she will present her work at a symposium Wednesday, July 27, at the University of Utah Guest House, 110 S. Fort Douglas Boulevard, 9 a.m.-3 p.m. Corkery is among 18 undergraduate students from universities […]

Living on borrowed time

July 21, 2016

Unfortunately, loss of plant and animal habitat leads to local species extinctions and a loss of diversity from ecosystems. Fortunately, not all of the extinctions occur at once. Conservation actions may still be able to save threatened species, according to William Newmark, a vertebrate zoologist at the Natural History Museum of Utah at the University […]


University of Utah School of Computing professor Sneha Kumar Kasera and his team of researchers are tasked with creating a crowdsourcing system that allows cellphone and laptop users to help detect and locate someone who is stealing bandwidth on radio frequency waves. The team has received a three-year, $1-million grant from the National Science Foundation (NSF) to devise the system to help tighten security of the nation’s radio spectrum, a valuable resource used for satellite communication and for commercial, public safety and military applications.

To catch a wireless thief

July 19, 2016

We crowdsource for business startups, art projects, inventions, even families in need. So why not ask cellphone users to contribute in helping catch high-tech thieves? University of Utah School of Computing professor Sneha Kumar Kasera and his team of researchers are tasked with creating a system that allows cellphone and laptop users to help detect […]

Size matters: Advance could increase sensitivity of liquid biopsies

July 18, 2016

The liquid biopsy, a new type of blood test for detecting and monitoring cancer, is a welcome reprieve from typical biopsies. The minimally invasive test could reduce the need for the sometimes painful and risky procedures involved in sampling tumors, particularly those that reside deep within the body. However, thus far, the utility of the […]

To save water on lawns, throw some shade

July 13, 2016

How much water does your lawn really need?  A University of Utah study re-evaluated lawn watering recommendations by measuring water use by lawns in Los Angeles. The standard model of turfgrass water needs, they found, lacked precision in some common urban southern California conditions, like the Santa Ana winds, or in the shade. “The current […]


University of Utah mathematicians Davit Harutyunyan, a research assistant professor, and Graeme Milton, a distinguished professor,  led a new study showing it is theoretically possible to design an ideal climbing rope for mountaineers and rock climbers. Such a rope would gradually bring a falling climber to a stop like applying brakes gradually can bring a vehicle to a safe stop.

Theoretical climbing rope could brake falls

July 5, 2016

University of Utah mathematicians showed it is theoretically possible to design ideal climbing ropes to safely slow falling rock and mountain climbers like brakes decelerate a car. They hope someone develops a material to turn theory into reality. In a new study in the Journal of Sports Engineering and Technology, the mathematicians write: “We do […]

Migratory bears down in the dumps

June 23, 2016

University of Utah biologists working in Turkey discovered two surprising facts about a group of 16 brown bears: First, six of the bears seasonally migrated between feeding and breeding sites, the first known brown bears to do so. Second, and more sobering, the other 10 bears stayed in one spot all year long: the city […]

Why people help distant kin

June 15, 2016

June 15, 2016 – It’s easy to understand why natural selection favors people who help close kin at their own expense: It can increase the odds the family’s genes are passed to future generations. But why assist distant relatives? Mathematical simulations by a University of Utah anthropologist suggest “socially enforced nepotism” encourages helping far-flung kin. […]

Pitch range produced by vocal cords

June 11, 2016

  Picture a singer, accompanied by a grand piano. As the singer’s voice dances through multiple octaves of range, the pianist’s fingers trip from one end of the keyboard to the other. Both the singer’s voice and the piano are dynamic instruments. But while the piano creates its music using the vibration of hundreds of strings, […]
