“Somewhere in the northern US, drones fly over a 2,000-acre preserve, protected by a nine-foot fence built to zoo standards. It is off-limits to curious visitors, especially those with a passion for epic fantasies or mythical creatures. The reason for such tight security? Inside the preserve roam three striking snow-white wolves—which a startup called Colossal Biosciences says are members of a species that went extinct 13,000 years ago, now reborn via biotechnology.

For several years now, the Texas-based company has been in the news for its plans to re-create woolly mammoths someday. But now it’s making a bold new claim—that it has actually “de-extincted” an animal called the dire wolf.”

Scientists have achieved what was once thought impossible by mapping both the activity and structure of 200,000 cells and their 523 million connections in a cubic millimeter of mouse brain. The project, called MICrONS, involved recording neural activity as mice watched videos, then creating detailed 3D maps of the brain tissue, revealing previously unknown patterns in neural wiring. Researchers are now working toward mapping an entire mouse brain, though mapping the human brain remains a distant goal. (via The New York Times)
