According to the National Institute of Mental Health, 1 in 3 people experience debilitating anxiety—the kind that prevents someone from going about their normal life. Women are also more at risk to suffer from anxiety. Yet the roots of anxiety and other anxiety-related diseases, such as Obsessive Compulsive Disorder (OCD), are still unclear. In a […]
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 […]
Access more multimedia files here. A few years ago, Scott Villa of Emory University had a problem. Then a graduate student at the University of Utah, he was stumped with an issue never addressed in school: How does one film lice having sex? Villa and University of Utah biologists had demonstrated real-time adaptation in their […]
All air-breathing vertebrates have a larynx—a structure of muscles and folds that protects the trachea and, in many animals, vibrates and modulates to produce a stunning array of sounds. But birds, although they have larynges (plural of larynx), use a different organ to sing. It’s low in the airway, down where the trachea branches to […]
When naturalist Charles Darwin stepped onto the Galapagos Islands in 1835, he encountered a bird that sparked a revolutionary theory on how new species originate. From island to island, finches had wildly varied beak designs that reflected their varied diets. The so-called Darwin’s finches are an emblem of adaptive radiation, which describes when organisms from […]
Gone are the days of heavy science textbooks with over-used examples and hard-to-grasp lessons. The Genetic Science Learning Center (GSLC) at the University of Utah is bringing science education into the 21st century with an online, interactive and multimedia curriculum that teaches up-to-date concepts in evolution and genetics to high school students. The newly released and […]
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 […]
As long as there have been birdwatchers, there have been lists. Birders keep detailed records of the species they’ve seen and compare these lists with each other as evidence of their accomplishments. Now those lists, submitted and aggregated to birding site eBird, can help scientists track bird populations and identify conservation issues before it’s too […]
A tiny snail may offer an alternative to opioids for pain relief. Scientists at the University of Utah have found a compound that blocks pain by targeting a pathway not associated with opioids. Research in rodents indicates that the benefits continue long after the compound have cleared the body. The findings were reported online in […]
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 […]
