U-led search team recovers new meteorites originally from the moon

September 20, 2019

In a year that celebrates the 50th anniversary of the Apollo 11 lunar landing and mankind’s first steps on the moon, U.S. explorers have once again brought home pieces of the moon for study- but this time from Antarctica, not Mare Tranquillitatis. Five meteorites, all pieces of a previously unknown lunar breccia (a sedimentary rock made of broken […]



“Fire inversions” lock smoke in valleys

September 11, 2019

Smoke from a summer wildfire is more than just an eye-stinging plume of nuisance. It’s a poison to the lungs and hearts of the people who breathe it in and a dense blanket that hampers firefighting operations. There’s an atmospheric feedback loop, says University of Utah atmospheric scientist Adam Kochanski, that can lock smoke in […]



Native foods are key to preserving rodent gut bacteria in captivity

September 5, 2019

Sept. 9, 2019 — As Rodolfo Martinez-Mota well knows, from the cactus spines in his clothes and skin, white-throated woodrats love to eat prickly pear cactus (from the Opuntia genus). They like the cactus so much that their gut microorganism community, or microbiome, is specially equipped to break down toxins in the cactus. But Martinez-Mota and […]



New rider data shows how public transit reduces greenhouse gas and pollutant emissions

August 26, 2019

Public transit has long been an answer for people looking to leave their car at home and reduce their air pollution emissions. But now, with better rider tracking tools, the University of Utah and the Utah Transit Authority can better answer the question: How much does public transit reduce pollution emissions? In a paper published […]



Utah’s red rock metronome

August 23, 2019

At about the same rate that your heart beats, a Utah rock formation called Castleton Tower gently vibrates, keeping time and keeping watch over the sandstone desert. Swaying like a skyscraper, the red rock tower taps into the deep vibrations in the earth—wind, waves and far-off earthquakes. New research from University of Utah geologists details […]



What we don’t know about prenatal opioid exposure

August 21, 2019

Aug. 28, 2019— Pregnancy can be a time of anxious uncertainty, particularly if there are any risks of complications. The question always arises, from parents, grandparents, friends and others: “Will the baby be OK?” In cases where the baby has been exposed to opioids in the womb, the answer is unclear. As part of a […]



Improving the odds of synthetic chemistry success

July 14, 2019

Chemistry is more than just mixing compound A with compound B to make compound C. There are catalysts that affect the reaction rate, as well as the physical conditions of the reaction and any intermediate steps that lead to the final product. If you’re trying to make a new chemical process for, say, pharmaceutical or […]



Where the Jordan River’s water comes from

June 27, 2019

Utah’s Jordan River, according to University of Utah professor Jennifer Follstad Shah, is a hard-working river, supporting a growing population of more than 1 million people. But underneath all of the irrigation canals and reclamation discharge, new research shows, are natural water sources that continue to shape the character of the Jordan River. The study […]



How trees affect the weather

June 19, 2019

Nature, said Ralph Waldo Emerson, is no spendthrift. Unfortunately, he was wrong. New research led by University of Utah biologists William Anderegg, Anna Trugman and David Bowling find that some plants and trees are prolific spendthrifts in drought conditions—“spending” precious soil water to cool themselves and, in the process, making droughts more intense. The findings […]



100-year-old physics model replicates modern Arctic ice melt

June 14, 2019

The Arctic is melting faster than we thought it would. In fact, Arctic ice extent is at a record low. When that happens—when a natural system behaves differently than scientists expect—it’s time to take another look at how we understand the system. University of Utah mathematician Ken Golden and atmospheric scientist Court Strong study the […]
