Big Data Is Only What We Make of It

In the final installment of the College of Science lecture series, the UA's Vincent J. Del Casino Jr. explains what defines big data, what its future holds and what it means for higher education.

No Volcanic Winter in East Africa From Ancient Toba Eruption

The supereruption 74,000 years ago did not trigger major environmental disruption that caused human populations in East Africa to decline, UA geoscientists say.

First Evidence of Ocean Warming Around Galápagos Corals

A UA-led team studied the natural temperature archives stored in coral and found the ocean around the Galápagos Islands has been warming since the 1970s.

UA Leads Project on Big Data and Black Holes

A worldwide collaboration has won a highly competitive award from the National Science Foundation to develop new ways of processing unprecedented amounts of data in real time.

To Buzz or to Scrabble? To Foraging Bees, That's the Question

Presenting bumblebees with various combinations of natural and artificial flowers laced with chemical and mechanical cues, UA biologists have discovered that for a bumblebee, foraging for pollen versus nectar is very different.

How Fast Is Greenland Melting?

A new analysis of Greenland's past temperatures will help scientists figure out how fast the island's vast ice sheet is melting, according to a new report from University of Arizona atmospheric scientists.

Asteroid Flyby to Help NASA Observation

For the first time, an actual, but harmless, space rock will be used for an observational campaign to test NASA's network of observatories and scientists who work with planetary defense.

The Science Behind Wildfires

Wildfires in Arizona have become more frequent and intense over time. As monsoon rains extinguished the 27,000-acre Burro Fire on Mount Lemmon, we asked University of Arizona fire ecologist Donald Falk to drive up with us and share his thoughts.

32 Students + 15,000 Insects Equals One Biological Clue

How does natural selection result in evolutionary change? A new method that dramatically reduces the complexity underlying how genetic information is translated into traits could provide biologists with a key.

Climate Change May Move Too Quickly for Grasses

Grasslands and grass crops, covering much of the world's land area and providing half of the calories humans eat, may be unable to respond quickly enough to a changing climate that is outpacing the plants' ability to adapt.
