Drones are proven for surveillance or delivery, but what's less widely known is their usefulness for herding elephants and seeing through walls.

Quick take: Businesses and non-profits are finding innovative ways to use drones to accomplish tasks that humans cannot do, and these developments have yielded benefits for environmental conservation, military strategy and more.

  • Drones in Hawaii have found rare plant species by flying to precarious spots like steep cliffs. (The Verge)
  • Researchers at the University of California in Santa Barbara have developed drones that see through walls, making them expert spies. As two drones navigate a closed structure, one emits a Wi-Fi signal, and the other picks it up. Together, they build a 3D image of the interior. (TechCrunch)
  • Drones found a till-then undiscovered ancient monument in Petra. It's the size of an Olympic swimming pool. (National Geographic)
  • Drones are herding elephants away from crops during harvest time in Tanzania. The pachyderms retreat when they spot the unmanned aircraft. (New Atlas)
  • An Italian project, "Paint By Drone," uses the aircraft to produce murals and designs on massive vertical surfaces. (CityLab)
  • In Australia, an engineer is developing drones that release germinated seeds to replace forests. She predicts the drones will be able to plant a billion trees a year to combat the climate effects of deforestation. (Australian Broadcasting Company)

Scoop: Gina Haspel threatened to resign over plan to install Kash Patel as CIA deputy

CIA Director Gina Haspel threatened to resign in early December after President Trump cooked up a hasty plan to install loyalist Kash Patel, a former aide to Rep. Devin Nunes (R-Calif.), as her deputy, according to three senior administration officials with direct knowledge of the matter.

Why it matters: The revelation stunned national security officials and almost blew up the leadership of the world's most powerful spy agency. Only a series of coincidences — and last minute interventions from Vice President Mike Pence and White House counsel Pat Cipollone — stopped it.

John Weaver, Lincoln Project co-founder, acknowledges “inappropriate” messages

John Weaver, a veteran Republican operative who co-founded the Lincoln Project, declared in a statement to Axios on Friday that he sent “inappropriate,” sexually charged messages to multiple men.

  • “To the men I made uncomfortable through my messages that I viewed as consensual mutual conversations at the time: I am truly sorry. They were inappropriate and it was because of my failings that this discomfort was brought on you,” Weaver said.
  • “The truth is that I'm gay,” he added. “And that I have a wife and two kids who I love. My inability to reconcile those two truths has led to this agonizing place.”
