With summer fast approaching, many turn their thoughts to swimsuit bods and summer tans. Now, a new genetic study might help explain why some of us burn while others tan.

The answer could help predict who gets skin cancer, because severe sunburns, particularly in childhood, strongly intensify skin cancer risk.

A team of researchers has applied a powerful genetic tool to the fight against the spotted wing fruit fly (Drosophila suzukii).

The destructive, invasive pest deposits its eggs inside of ripening fruit.

One of the world’s rarest, largest and foulest flowers will bloom Thursday night at the Tucson Botanical Gardens.

Amorphophallus titanum, better known as the corpse flower for its signature rotting-carcass odor, can take 7-10 years or longer to bloom.

An international team of researchers has reported what may be the first two isolated, salty, subglacial lakes found on Earth.

The water pockets — one roughly the area of Arizona’s Saguaro Lake, the other about four-fifths the size of the state’s Apache Lake — differ from 400 other subglacial pools in that they are 4-5 times as salty as Earth’s oceans.
