How antifreeze proteins stop ice cold

Researchers at the University of Utah and University of California, San Diego discovered how antifreeze proteins function, providing a direction for future research. The study found that AFPs prevent water from freezing by surrounding and binding to small ice crystals, preventing their spread.

Utah soil's slippery grip on nutrients

Researchers found that lawns in Salt Lake Valley up to 100 years old show no signs of being saturated with fertilizer nutrient nitrogen, contradicting previous studies. The study suggests that natural processes may account for the unusual pattern, including storage in the soil and losses through groundwater leaching.

Black + white = Not white

A new study by University of Utah professor Jacqueline M. Chen found that observers categorize black-white multiracial individuals as non-white, influenced by a powerful minority bias. This phenomenon has significant implications for multiracial individuals' social experiences and race relations in the US.

Power to the people

The University of Utah's Masood Parvania is developing microgrid controllers that can distribute electrical power more efficiently and securely in case of a power outage. His team will test these technologies on a new laboratory setup, also aiming to educate the next generation of power engineers.

How animals holler

Research by Ingo Titze and Anil Palaparthi found that animals' high radiation efficiency is due to wide mouths, high frequencies, and body acoustical reflecting chambers. Humans lack these traits, limiting our ability to make long-range calls like animals do. The study aims to improve human call efficiency for emergency situations.

A bolt of insight

A team led by the University of Utah has observed lightning-triggered gamma-rays in more detail than ever before, detecting 10 bursts of downward terrestrial gamma ray flashes between 2014 and 2016. The study provides a major advance in understanding the production mechanism of these rare and high-energy radiation events.

Riding the (quantum magnetic) wave

Scientists have successfully converted quantum waves into electrical current using an organic-based magnet, paving the way for faster and more efficient electronics. The breakthrough, achieved by researchers at the University of Utah, could lead to new generations of electronic systems that use magnons instead of electrons.

U CO2 sensor network shows effects of metro growth

The U CO2 sensor network, the only multisite urban CO2 network worldwide with over a decade of continuous measurements, shows that suburban sprawl significantly impacts metro area CO2 emissions. The network reveals that suburban expansion increases CO2 emissions more than similar population growth in urban areas.

Reaching the breaking point

A new study from the University of Utah suggests that repeated stress from everyday activities like walking can cause microdamage to bones in older adults, leading to a higher risk of breakage. This theory, known as 'cyclic loading,' challenges the common-held belief that bone breaks are caused by single impacts or forces.

Climate change and snowmelt -- turn up the heat, but what about humidity?

Researchers found that changes in humidity determine how much snowpack contributes to streams, lakes, and groundwater as the climate warms. Cloudy, humid winter days cause snowpack to warm faster, increasing melt during winter months. In contrast, clear skies and low humidity preserve the snowpack until spring. The study highlights the...

How ice in clouds is born

Scientists have found that water droplets in clouds can turn to ice more rapidly than previously predicted, with a disordered ice structure forming under certain cloud conditions. This discovery reconciles theoretical models of clouds with observations of freezing rates, helping cloud modelers understand better their observational data.

Is he really that into you?

Women who experienced painful father-child relationships perceive greater mating intent in men and exhibit increased sexual arousal when viewing male faces. This study highlights the potential for early childhood experiences to shape adult mating behavior and increase the likelihood of engaging in unrestricted or risky sexual activity.

Waves in lakes make waves in the Earth

Scientists have discovered that waves in lakes can generate microseismic signals that can reveal subsurface geology and track ice cover duration. By analyzing these signals, researchers can create a seismic 'CT scan' of the Earth, providing valuable insights into geological structures.

Old Faithful's geological heart revealed

Researchers used dense seismograph network to map near-surface geology around Old Faithful, discovering a reservoir of heated water that fuels the geyser. The study also reveals how ground shaking behaves between eruptions and finds an underground feature affecting seismic waves in a specific area.

What it takes to recover from drought

A study found that drought recovery depends on post-drought weather conditions and location. In general, most areas recover in under six months, while high-latitude regions need up to two years. Climate models predict more frequent droughts, which could lead to a double whammy effect if ecosystems are hit before they recover.
