Scientists now use real-time tracking to help protect endangered elephants

Endangered elephants in Africa are being tracked in real-time using GPS, accelerometers and algorithms to protect them from poachers, Scientific American reports.

How it works: GPS combined with algorithms developed for analyzing data collected by the collars can detect if an elephant stops moving or slows down (indicating it could be injured or dead), or when it heads in the direction of a well-known poaching area.

Paul Allen's Vulcan and the non-profit Save the Elephants developed an app that sends alerts to rangers so they can intervene when a potential problem arises. The app provides positions of other rangers, camera trap feeds, gunshot detection and more. Batian Craig, director of a company that oversees security at Lew Wildlife Conservancy in Kenya, told SciAm it is "a game changer."

Elephant endangerment: Between 2007 and 2014, the savanna elephant population dropped by 30%; the forest elephants dropped by 62% between 2002 and 2011.

The S&P 500 closed up 7% on Monday, while the Dow rose more than 1,500 points.

Why it matters: The huge market surge comes amid rare optimistic signs that the spread of the coronavirus may be slowing in parts of the country, including New York. But government officials say this will be a difficult week, while economists — including former Fed chair Janet Yellen today — warn that the pandemic could have a catastrophic impact on the global economy.

U.K. Prime Minister Boris Johnson has been taken to the intensive care unit of St. Thomas Hospital in London due to increasingly severe coronavirus symptoms.

The backdrop: Johnson was admitted to the hospital on Sunday for what Downing Street called "routine tests" because his condition had not improved 10 days after he tested positive for the virus. His condition has since "worsened," according to a statement, and Foreign Secretary Dominic Raab will step into his place "where necessary."
