Triple-negative breast cancer accounts for about 10 to 15% of all breast cancers. Researchers have developed a drug they hope can treat it with little to no toxic side effects.
Why do some animals have bright colors to impress mates while others use them to ward off predators? It depends on their ancestors, new research reveals. Species that use bright colors as a sexual signal had ancestors that were active during the day, whereas species that use them as warning signals had ancestors that were active at night.
Maps of Earth's temperature and rainfall 56 million years ago could provide insight into the planet's future as carbon dioxide levels in the atmosphere increase.
Shock-darkened meteorites are characterized by dark veins. Planetary scientists have been unable to pinpoint a nearby asteroid source of these meteorites – until now.
Researchers at UArizona and Penn State University are drawing inspiration from bacteria under the sea to develop technology capable of capturing and repurposing methane, an extremely potent greenhouse gas.
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.
After decades of development, a nail-biting launch and months of space travel and commissioning, NASA has released the first images captured by the James Webb Space Telescope. The images hint at the beginning of years of space science, made possible in part by the 21 UArizona researchers who have played a role in developing and managing Webb's onboard instruments.
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.
As the Colorado River carved the Grand Canyon, it flushed away ancient groundwater. The discovery was made using a new method that determines the age of water based on how much of the radioactive element krypton-81 is present.
Desert dwellers know it well: the smell of rain and the feeling of joy that comes with it. The familiar fragrance, which is the result of oils and chemicals released by desert plants, may offer stress-reducing health benefits, University of Arizona research suggests.
