Giant Magellan Telescope will discover, surprise

Galileo was the first person to point a telescope toward the heavens, and his observations of the moons of Jupiter changed how we understand our place in the universe. Four centuries of advances in telescope size and sophistication have brought unexpected returns, including evidence for dark…

Harvesting heat with quantum mechanics

Most Tucsonans would agree that Tucson has more than enough heat to go around, but few think our excess heat is good for anything.

UA Science: Enriching understanding of our world

This has been a good year for science at the University of Arizona - and for Tucson.

Teens create fun math, science games

This spring, more than 300 Arizona middle and high school students played "Teach Ourselves," an online game that entices students to master math and science. The game awards points and badges to the students when they successfully solve problems.

Capturing the 'when' of life by better integration of time, information

You purchase a book from an online seller. The government keeps records of your Social Security contributions. The University of Arizona tracks the courses a student takes.

New statistics mine human genome for improved cancer therapies

Traditional cancer diagnosis relies on procedures such as tumor biopsy, imaging and other tests. Although effective to indicate cancer stages, these assays can fail to reveal the cancer's genetic subtypes that would help physicians make personalized treatment decisions.

Delicious poisons from plants and why wasabi is hot

My students and I study how and why plant toxins evolved and how attackers of plants, including humans, detoxify these molecules.

Recovering language skills

Until Congresswoman Gabri-elle Giffords was shot in the head on Jan. 8, 2011, most people had never heard the word "aphasia," which means difficulty talking, reading and writing as a result of brain damage.

STEM Center will connect students, teachers to Science City

The University of Arizona has a proud tradition of integrating teaching, research and outreach in science, technology, engineering and mathematics, commonly referred to as STEM fields. Indeed, the UA programs are so numerous and diverse that potential participants can get lost in the thicket…

'Un-dicing' Arizona's copper carrots

Chopped vegetables may seem an unlikely metaphor for the formation of copper deposits. However, one of geology's enduring challenges is deciphering how faults caused by earthquakes have diced the Earth's crust and, in the process, interleaved ore-bearing pieces with other rocks.

Climate projection: Drier with chance of pouring rain

Together with colleagues and students at the University of Arizona's department of atmospheric sciences, we are improving projections of future climate for the Southwestern United States.

Bringing molecules together to fight type 2 diabetes

In addition to the changes we can see with our eyes when a person becomes overweight, changes also occur in the person's blood and cells. One of these changes is a decline in the blood levels of a hormone called adiponectin.

Climate, Mediterranean cultures, change

After the record-breaking heat waves of summer 2012 and other weather disasters this fall, the threat of climate change continues to confront us.

Painting the future of energy production

Imagine this: No monthly electricity bills, no power outages because of summer storms. All you need?

Giant Magellan Telescope will discover, surprise

The advantage of the Giant Magellan Telescope’s adaptive optics technology shows clearly when comparing simulated images of a dense star field using the GMT (left) and the Hubble Space Telescope (right).

Climate, Mediterranean cultures, change

Tree rings from ancient cypress trees such as this one on Crete can reveal the Mediterranean region's climate history up to 1,000 years into the past: vital information for UA researchers studying human and environmental histories.
