  1. For the first time, scientists have begun to figure out why the disfiguring skin lesions caused by cutaneous leishmaniasis don't hurt.
  2. During a two-year survey of soft corals in the Florida Keys,  scientists identified three species of octocorals that have survived heat waves. While the coral animal itself may be heat tolerant, scientists concluded that the symbiotic algae inside the coral serve as a protector of sorts.
  3. Scientists sequenced the genome of the East Asian pitcher plant, Nepenthes gracilis, a species of carnivorous plant related to Venus flytraps, as well as sundews, beets and spinach.
  4. By studying the skull shapes of dipsadine snakes, researchers have found how these species of snakes in Central and South America have evolved and adapted to meet the demands of their habitats and food sources.
  5. In sea fireflies' underwater ballet, the males sway together in perfect, illuminated synchronization, basking in the glow of their secreted iridescent mucus.
  6. As California, the U.S. and the world work to make good on commitments to conserve 30% of oceans and lands by 2030, all strategies are on the table -- and under the microscope. When it comes to the ocean, one valuable tool is marine protected areas (MPAs), regions that are defined, designated and managed for long-term conservation. Among other benefits, MPAs protect habitats and promote species diversity. They also hold value for communities and industries.  
  7. Maize is one of the world's most widely grown crops. It is used for both human and animal foods and holds great cultural significance, especially for indigenous peoples in the Americas. Yet despite its importance, the origins of the grain have been hotly debated for more than a century. Now new research shows that all modern maize descends from a hybrid created just over 5000 years ago in central Mexico, thousands of years after the plant was first domesticated.
  8. There's a species of ant that is so rare, only a handful of records exist from across the entire eastern United States. North Carolina State University researcher Michelle Kirchner not only found these ants in the Triangle region of North Carolina, she is the first to document an entire colony for scientists, taxonomists and ant-thusiasts everywhere. It is the first time males of the species have been collected or photographed.
  9. A new bacterial species discovered at the deep-sea hydrothermal vent site 'Crab Spa' provides a deeper understanding of bacterial evolution.
  10. Scientists have analyzed more than 3.8 million volunteer hours of birdwatching data to identify Australia's most elusive species.
