Research conducted in Melanie Culver's lab used the latest in genomic technologies to determine whether the endangered Mexican wolf had hybridized with domestic dogs.
On May 27, NASA's Terra satellite captured an infrared image of subtropical storm Alberto's center of circulation hundreds of miles south of the Florida panhandle. A thick band of thunderstorms east of the center extended over the entire state of Florida. (Photo: NASA)

The UA's hurricane forecasting model, known for its accuracy, is calling for fewer hurricanes in the Atlantic this year. Researchers are predicting four hurricanes, two of which will be major — those reaching Category 3, 4 or 5. Last year brought six major hurricanes, including Irma and Maria (each a 5).

Research by anthropologist Stacey Tecot shows that lemur fathers experience elevated levels of androgens (male sex hormones) when they care for their infants — which wasn't expected.
The Orion Nebula is a star-forming region in the Milky Way, and one of the most famous of the astronomical nebulas. Here, insets show where planetary systems are forming in the Orion. (Image: NASA, ESA, M. Robberto of STScI/ESA, HST Orion Treasury project team, and L. Ricci ESO)

A team of scientists led by the UA has imaged a cluster of about 110 protoplanetary disks in the Orion Nebula, and the findings may provide insights into the birth of our solar system.

An international scientific team that includes UA geoscientist Christopher Harig reports that a sharp uptick in the loss of Antarctic ice since 2012 is contributing to rising seas.
Last July — one of the wettest months on record in Tucson — produced more than six inches of rain. That included one spell in which the city received two inches in less than a week. (Photo: Bob Demers/UANews)

Our stormy season officially starts on Friday, and the forecast is for above-average rainfall and warmer-than-average temperatures. The storms provide up to half of Tucson's annual rainfall.

The asteroid that blew up in the sky on June 2 was discovered by the UA-led Catalina Sky Survey using a telescope that helped discover about half of all known near-Earth objects.
Our Milky Way's largest neighbor, the Andromeda Galaxy, spans about 220,000 light-years across. Two of its dwarf satellite galaxies, Messier 110 (bottom left) and Messier 32 (above Andromeda's central bulge), are visible as bright white spots in this image taken by UA astrophotographer Adam Block.

Pinning down the mass of a galaxy may seem like an esoteric undertaking, but UA scientists think it holds the key to unraveling the nature of dark matter and the fabric of our cosmos.
