Variations of a single gene drive diverse pigeon feather patterns

July 17, 2018

In a new study, a University of Utah-led team has discovered that different versions of a single gene, called NDP (Norrie Disease Protein), have unexpected links between color patterns in pigeons, and vision defects in humans. These gene variations were likely bred into pigeons by humans from a different pigeon species and are now evolutionarily advantageous […]



VERITAS SUPPLIES CRITICAL PIECE TO NEUTRINO DISCOVERY PUZZLE

July 11, 2018

The VERITAS array has confirmed the detection of high-energy gamma rays from the vicinity of a supermassive black hole located in a distant galaxy, TXS 0506+056. While these detections are relatively common for VERITAS, this blackhole is potentially the first known astrophysical source of high-energy cosmic neutrinos, a type of ghostly subatomic particle that can […]



That sound makes me dizzy

July 10, 2018

For some people, certain sounds like a trumpet blowing a particular tone can make them dizzy, and it’s not because they’re giddy from a Wynton Marsalis melody. It has been estimated that 1 in 100 people around the world have a congenital inner ear condition known as semicircular canal dehiscence, a thinning of the bone […]



How Antifreeze Proteins Stop Ice Cold

July 10, 2018

How do insects survive harsh northern winters? Unlike mammals, they don’t have thick coats of fur to keep warm. But they do have antifreeze. Antifreeze proteins (AFPs) prevent ice from forming and spreading inside their bodies. The existence of these AFPs has been known for decades, but the mechanisms governing this unique survival technique have […]



Physicists uncover why nanomaterial loses superconductivity

July 5, 2018

The struggle to keep drinks cold during the summer is a lesson in classical phase transitions. To study phase transitions, apply heat to a substance and watch how its properties change. Add heat to water and at the so-called “critical point,” watch as it transforms into a gas (steam). Remove heat from water and watch […]



NASA’s NuSTAR mission proves superstar Eta Carinae shoots cosmic rays

July 3, 2018

A new study using data from NASA’s NuSTAR space telescope suggests that Eta Carinae, the most luminous and massive stellar system within 10,000 light-years, is accelerating particles to high energies — some of which may reach Earth as cosmic rays. “We know the blast waves of exploded stars can accelerate cosmic ray particles to speeds […]



New database sheds light on early history of black members in the LDS Church

July 2, 2018

Paul Reeve, professor of history at the University of Utah, and the J. Willard Marriott Library have collaborated to develop a public history project, “Century of Black Mormons,” a database that illuminates the history of black members in The Church of Jesus Christ of Latter-day Saints. The database was unveiled on June 30 at “Black, […]



Utah soil’s slippery grip on nutrients

July 2, 2018

Lawns in the Salt Lake Valley up to 100 years old are not yet saturated in the nutrient nitrogen, which is added by fertilizer, according to a new study from University of Utah researchers. The result is surprising, since previous studies in the Eastern U.S. suggested that fertilized soil would become saturated with nitrogen within […]



Documenting 75 years at Hill Air Force Base

July 2, 2018

In time for the nation’s 242nd birthday, the University of Utah’s J. Willard Marriott Library is celebrating an exciting new addition to Utah Digital Newspapers—the complete run of Hill Air Force Base’s Hilltop Times. More than 61,000 pages of the Hill Air Force Base newspapers, covering the period 1943 to 2006, have been digitized by the […]
