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 patterns…

Lensless Camera Functions as Sensor
In the future, your car windshield could become a giant camera sensing objects on the road. Or each window in a home could be turned into a security camera. University of Utah electrical and computer engineers have discovered a way to create an optics-less camera in which a regular pane of glass or any see-through…
Physicists Uncover Why Nanomaterial Loses Superconductivity
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…

Nano-Decorations Keep Water Clean
When bacteria and viruses get into well water and make people sick, often the contamination comes after heavy rain or flooding. In 2000, more than 2,300 people in Walkerton, Ontario, got sick when, after unusually heavy rains. E. coli bacteria found their way to drinking water wells. Seven people died. The reason appears straightforward —…

Epigenetics May Explain How Darwin’s Finches Respond to Rapid Environmental Change
Holograms Taken to New Dimension
Technology developed by a team of University of Utah electrical and computer engineers could make the holographic chess game R2-D2 and Chewbacca played in “Star Wars” a reality. The team led by electrical and computer engineering associate professor Rajesh Menon has discovered a way to create inexpensive full-color 2-D and 3-D holograms that are far…
Electronics Get a New Spin
A University of Utah-led team has discovered that a class of “miracle materials” called organic-inorganic hybrid perovskites could be a game changer for future spintronic devices. Spintronics uses the direction of the electron spin — either up or down — to carry information in ones and zeros. A spintronic device can process exponentially more data…

Flipping the Switch on Ammonia Production
Nearly a century ago, German chemist Fritz Haber won the Nobel Prize in Chemistry for a process to generate ammonia from hydrogen and nitrogen gases. The process, still in use today, ushered in a revolution in agriculture, but now consumes around one percent of the world’s energy to achieve the high pressures and temperatures that…
Snails’ Speedy Insulin
University of Utah researchers have found that the structure of an insulin molecule produced by predatory cone snails may be an improvement over current fast-acting therapeutic insulin. The finding suggests that the cone snail insulin, produced by the snails to stun their prey, could begin working in as few as five minutes, compared with 15…
Engineers Discover Highly Conductive Materials for More Efficient Electronics
Engineers from the University of Utah and the University of Minnesota have discovered that interfacing two particular oxide-based materials makes them highly conductive, a boon for future electronics that could result in much more power-efficient laptops, electric cars and home appliances that also don’t need cumbersome power supplies. Their findings were published this month in…
Living on Borrowed Time
Unfortunately, loss of plant and animal habitat leads to local species extinctions and a loss of diversity from ecosystems. Fortunately, not all of the extinctions occur at once. Conservation actions may still be able to save threatened species, according to William Newmark, a vertebrate zoologist at the Natural History Museum of Utah at the University…
Pitch Range Produced by Vocal Cords
Picture a singer, accompanied by a grand piano. As the singer’s voice dances through multiple octaves of range, the pianist’s fingers trip from one end of the keyboard to the other. Both the singer’s voice and the piano are dynamic instruments. But while the piano creates its music using the vibration of 88 strings, the…
Let There Be Light
University of Utah materials science and engineering associate professor Mike Scarpulla wants to shed light on semiconductors — literally. Scarpulla and senior scientist Kirstin Alberi of the National Renewable Energy Laboratory in Golden, Colorado, have developed a theory that adding light during the manufacturing of semiconductors — the materials that make up the essential parts…
