New Hubble Space Telescope capture and more: Understand the world through 7 images

Researchers completed a CT scan of an entire woolly mammoth tusk for the first time. Larger CT scanners have allowed scans that weren’t possible before. The scan revealed the seven-foot-long tusk belonged to an approximately 32-year-old mammoth that lived 17,000 years ago.

Researchers discovered a new species of deep-sea isopod, Bathonymus yucatanensis, in the Gulf of Mexico. Relatives of pillbugs, the crustaceans can grow up to 10 inches long.

Researchers determined collagen type XII drives breast cancer tumors to metastasize. High levels of collagen XII may be used to predict more aggressive tumors, and scientists are investigating the finding’s therapeutic potential.

Researchers found 13 of the 19 glaciers in Alaska’s Kenai Fjords National Park are retreating, with those that end in lakes retreating the most. Their measurements will provide a baseline for future climate change studies and may aid land management.

Researchers created a medical implant that resists being surrounded by scar tissue. By repeatedly inflating and deflating, the device prevents immune cells from building up around it, meaning it can last much longer in the body.
