Snow algae: Investigating how algal blooms impact mountain snowpack

Scott Hotaling, an Assistant Professor in the Department of Watershed Sciences in the Quinney College of Natural Resources, is exploring how the watermelon-tinted blooms of snow algae impact mountain snowpack—where they come from, what triggers a bloom, and what factors influence the size, scale and magnitude of snow algal blooms.

How does a drying Great Salt Lake affect carbon cycling?

As water levels at the lake continue to decline, the complex natural systems the lake supports are shifting, too. Ecohydrologist Erin Rivers from the Quinney College of Natural Resources is investigating how shifting water levels at the Great Salt Lake are altering the way it captures and stores carbon.

New study of continental margins could provide better understanding on the way to a carbon-neutral economy

Pangaea was the name Alfred Wegener gave to the supercontinent that existed on Earth 250 million years ago. Over the course of many millions of years, this supercontinent broke into different pieces, which became the landmasses we see on the globe today. Extensional forces on the tectonic plates causes continents to break apart—as Pangaea once did—creating new ocean basins. Large parts of...

Scientists find world's oldest European hedgehog

The world's oldest scientifically-confirmed European hedgehog has been found in Denmark by a citizen science project involving hundreds of volunteers. The hedgehog lived for 16 years, 7 years longer than the previous record holder.

Organizations should change cultures to support excellence and dismantle barriers created by systemic racism: Report

To increase diversity, equity, and inclusion in STEMM fields, higher education institutions and STEMM organizations should go beyond a focus on simply increasing the numeric participation of minoritized racial and ethnic groups and act to change their organizational cultures and environments, says a new report from the National Academies of Sciences, Engineering, and Medicine.

7 new spider species discovered in caves in Israel

In a new study conducted by researchers from the Hebrew University of Jerusalem and University of Madison-Wisconsin, seven new species of funnel web spiders (Agelenidae, Tegenaria), unique to caves in Israel, were discovered. These species join a large number of invertebrates recently found in Israeli caves that are new to science.

Complex subsurface of Mars imaged by Chinese rover Zhurong

Ground-penetrating radar from China's Martian rover Zhurong reveals shallow impact craters and other geologic structures in the top five meters of the Red Planet's surface. The images of the Martian subsurface are presented in a paper published in Geology.

Securing supply chains with quantum computing

The Russo-Ukrainian conflict and the COVID-19 pandemic have shown how vulnerable global supply chains can be. International events can disrupt manufacturing, delay shipping, induce panic buying and send energy costs soaring.

The perfect pour: Model predicts beer head features

From creating drinks with distinctive looks to providing aromas for connoisseurs, beer foam is big business. The complex interplay between the components of a beer, the vessel from which it's poured, and the glass it's poured into has garnered plenty of attention from researchers, brewers, and drinkers. A new study looks to provide the most accurate predictions for how a beer will foam.

Newly discovered components of Dendrolimus pini sex pheromone

Beyond the seven mountains and forests, a hungry beast was stealing away. Does this sound like a fairy tale? In reality, such a beast does exist. It is the caterpillar of the nocturnal pine-tree lappet moth (Dendrolimus pini, L.), which feeds on pine needles and wreaks havoc in the forests on a massive scale.

'Magic' solvent creates stronger thin films

A new all-dry polymerization technique uses reactive vapors to create thin films with enhanced properties, such as mechanical strength, kinetics and morphology. The synthesis process is gentler on the environment than traditional high-temperature or solution-based manufacturing and could lead to improved polymer coatings for microelectronics, advanced batteries and therapeutics.

Teachers apply unequal criteria when assessing giftedness, finds study

Researchers at the Universities of Tübingen and Maastricht have found that teachers are one and a half times more likely to suspect that boys are gifted than girls who are equally gifted. Moreover, the researchers say, teachers are more likely to rate children from families with a high level of education as highly gifted. The study has been published in the journal Gifted Child Quarterly.

NASA's Perseverance rover shows off collection of Mars samples

Even space robots know what "pics or it didn't happen" means: NASA's Perseverance Mars rover provided a panorama of its recently completed sample depot—a big milestone for the mission and humanity's first collection of samples on another planet. The panorama, stitched together from 368 images that were sent to Earth, captures more than a month of careful placement and mapping of 10 titanium...

Woody vine may help prevent kidney stones

Urolithiasis is usually treated by surgery. However, the high recurrence rate and high cost of treatment call for a non-surgical medical solution. In the Dai minority region of China, the perennial woody vine of Aspidopterys obcordata (Hei Gai Guan) has been used as a folk medicine for the treatment of urinary tract infections, cystitis and urinary tract stones and also treated as a drink for the...

Study reveals mystery of Paleozoic ostracod evolution

Ostracoda is one of the most widespread and diverse groups of crustaceans since the Early Ordovician. The subclass Podocopa are the most abundant ostracods during the Palaeozoic. However, its origin, evolution, ontogeny and phylogeny are poorly understood due to the lack of soft-part and molecular evidence, especially for the order Platycopida.
