Yeast cells and human immune system cells rely on similar chemical reactions to know when to grow. Scientists have identified differences between the cell types that could help with the development of antifungal drugs.
Ever wonder what gives a forest its pine-fresh scent? The answer is the molecular compound pinene, naturally released by plants. A new study explores how and under what conditions plants emit pinene and other volatile organic compounds into the atmosphere. The results may help scientists detect when an ecosystem is in distress.
Chemical and environmental engineering professor Erin Ratcliff will lead a national collaboration to create solar fuels and storage technologies that are more durable and sustainable, but less expensive.
Adults ages 60 and older who sit for long periods watching TV or engaging in other passive, sedentary behaviors may be at increased risk of developing dementia, according to a new study.
Nature is full of patterns. Among them are tiling patterns, like what you see on a giraffe's coat. But what makes these natural patterns form? A new UArizona study uses bacteria to help answer that question.
University of Arizona students and faculty members completed a comprehensive study to track and characterize satellites, using a ground-based sensor they developed to measure satellites' brightness, speed and paths through the sky.
Analyses based on locations and viral sequencing of early cases indicate the COVID-19 pandemic started in Wuhan's Huanan Seafood Wholesale Market, with two separate jumps from animals to humans.
Before-and-after data from the few seconds it took the OSIRIS-REx spacecraft to collect a sample from asteroid Bennu revealed a surprise: The particles of Bennu's exterior are so loosely packed, they act more like a fluid than a solid.
In many cases of epilepsy – which disrupts electrical activity in the brain and often results in seizures – the underlying cause is unknown. UArizona researchers may have found an explanation for some forms of epilepsy.
A concept developed by UArizona aerospace experts and a NASA planetary scientist takes inspiration from albatross flight to learn more about the Red Planet's atmosphere and geology.
