A young star called Formalhaut that is home to at least one alien planet is also ringed by a vast, dusty cloud of comets, like our own solar system. But there's a big difference: There may be as many as 83 trillion comets there, with collisions destroying thousands each day, a new study suggests. [Read full story]

A new national park in Russia is an attempt to save the world's rarest cat, the Amur leopard. The park, announced Tuesday (April 10) by the World Wildlife Fund (WWF), encompasses 650,000 acres (262,000 hectares) of Amur leopard breeding area in Russia's Far East. Now called the Land of the Leopard National Park, the park covers about 60 percent of the critically endangered cat's habitat.
Shown here, a female Amur leopard named Narva had recently had cubs as indicated by the small tracks in the snow in her range. [Read full story]
New research reported this week reveals why it's good to get naked for some organisms. The study found the molting process, in which crustaceans and insects lose their exoskeleton in order to form a new one may actually protect molting animals from parasites.
Shown here, a water flea (Daphnia magna) undergoes molting. Like all crustaceans, this tiny creature must molt to grow. [Read full story]
