UA researchers have created a first-of-its-kind thermostat add-on that reliably predicts electricity costs, putting consumers in control of balancing their comfort and budget.

Researchers at the University of Arizona, with the support of Tech Launch Arizona, are one step closer to giving consumers something they’ve never had before: a way to easily and instantly make informed decisions about the trade-off between comfort and the cost of electricity for heating and cooling, which typically accounts for half of a home’s electricity bill.

Were Dinosaurs Cold-Blooded or Warm-Blooded? Neither, Study Finds

A study that originated in the lab of UA biologist Brian J. Enquist with UA alum John Grady suggests dinosaurs had a metabolism that was neither warm- nor cold-blooded, but somewhere in between.

Dinosaurs dominated the Earth for more than 100 million years, but all that remains today are bones. This has made it difficult to solve a long-standing and contentious puzzle: Were dinosaurs cold-blooded animals that lumbered along or swift warm-blooded creatures like those depicted in “Jurassic Park”?

UA physicists have discovered how to change the crystal structure of graphene. The finding could lead to smaller and faster microprocessors.

A University of Arizona-led team of physicists has discovered how to change the crystal structure of graphene, more commonly known as pencil lead, with an electric field, an important step toward the possible use of graphene in microprocessors that would be smaller and faster than current, silicon-based technology.

Mystery of 1918 Pandemic Flu Virus Solved by UA Researchers

University of Arizona researcher Michael Worobey and his team have discovered that the key to understanding influenza pandemics may lie in flu exposure during childhood.

Just as the world was recovering from the devastation of World War I, another killer swept across the globe. A deadly flu virus attacked more than one-third of the world’s population, and within months had killed more than 50 million people – three times as many as the war – and had done it more quickly than any other illness in recorded history.

UA Researcher and Colleagues Discover the Birthplace of the Chili Pepper

Researchers have found that central-east Mexico gave birth to the domesticated chili pepper, which is now the world’s most widely grown spice crop.

In the Southwest, the chili pepper is practically a dietary staple. It gives salsa a spicy crunch, it brings depth to Mexican sauces, and it provides an extra kick to Sonoran hot dogs.

Plenty of other world cuisines rely on it too, from China to India to Thailand. But Latin America, researchers have confirmed, is where it started. (more…)

Ancient Fossil Reveals Oldest Known Circulatory System

A fossil creature buried in an “invertebrate version of Pompeii” more than half a billion years ago reveals the first-known cardiovascular system in exquisitely preserved detail.

An international team of researchers from the University of Arizona, China and the United Kingdom has discovered the earliest known cardiovascular system, and the first to clearly show a sophisticated system complete with heart and blood vessels, in fossilized remains of an extinct marine creature that lived over half a billion years ago. The finding sheds new light on the evolution of body organization in the animal kingdom and shows that even the earliest creatures had internal organizational systems that strongly resemble those found in their modern descendants.

A comparison of images taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter in November 2010 and May 2013 reveal the formation of a new gully channel on a crater-wall slope in the southern highlands of Mars.

FLAGSTAFF, Ariz. — Researchers at the U.S. Geological Survey, the University of Michigan, the University of Arizona, and the University of Technology, Sydney (Australia) are collaborating with scientists in Brazil on a three-year research project that investigates a basic yet unanswered question in Earth-system and global carbon-cycle science: What controls the response of photosynthesis in Amazon tropical forests to seasonal variations in climate?

Results of the study will help improve the reliability of global climate forecasts by guiding improvements in the treatment of tropical forest photosynthesis and related water-cycle processes in Earth-system models. (more…)
