Video game created by U students helps combat lazy eye in kids

August 16, 2016

A leading cause of vision loss in children is amblyopia, or lazy eye, and video game developers from the University of Utah have come up with a way to not only diagnose but to treat the disorder. In 2015, U students Ahmad Alsaleem, Ahmad Nassari and Daniel Blair from Entertainment Arts & Engineering won a […]

Ecology on the runway

August 10, 2016

University of Utah ecologist Nalini Nadkarni is no fashion mogul. But she is a scientist actively engaged in public outreach, working to bring the wonder and curiosity of the natural world to people, even those who may have no interest in natural history museums, nature documentaries or natural history magazines. Those people probably care about […]

Population boom preceded early farming

July 28, 2016

University of Utah anthropologists counted the number of carbon-dated artifacts at archaeological sites and concluded that a population boom and scarce food explain why people in eastern North America domesticated plants for the first time on the continent about 5,000 years ago. “Domesticated plants and animals are part of our everyday lives, so much so […]

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 […]
