UA Researchers Reveal Elusive Molecule

A long-standing chemistry puzzle has been solved, with potential implications ranging from industrial processes to atmospheric chemistry.

Scientists at the University of Arizona have discovered a mysterious molecule with a structure simple enough to make it into high school textbooks, yet so elusive that chemists have argued for more than a century over whether it even exists. (more…)

How Longhorned Beetles Find Mr. Right

Smelling good is just part of what some beetles must do to find a mate. They have to exude the proper perfume at the right time of day and right season of the year, a UA-led team found.

A longhorned beetle’s sexy scent might make a female perk up her antennae. But when the males of several species all smell the same, a female cannot choose by cologne alone. (more…)

Viruses: Tiny Teachers of Biology

Imagine that an invisible, microscopic invader has found its way into your body and hijacked the cellular machinery that keeps you healthy. Inhabiting the gray area between living and nonliving, the invader can only reproduce once it makes its new home inside of your cells, eventually causing you to fall ill. How do physicians and scientists combat this uninvited guest? (more…)

Asian Monsoon Much Older Than Previously Thought

Scientists originally thought the climate pattern began 22-25 million years ago as a result of the uplift of the Tibetan Plateau and the Himalaya Mountains. But UA researchers say that’s not going back far enough.

The Asian monsoon already existed 40 million years ago during a period of high atmospheric carbon dioxide and warmer temperatures, reports an international research team led by a University of Arizona geoscientist. (more…)

Don’t Underestimate Your Mind’s Eye

UA study finds that objects in our visual environment needn’t be seen in order to impact decision making.

Take a look around, and what do you see? Much more than you think you do, thanks to your finely tuned mind’s eye, which processes images without your even knowing. (more…)
