Although giant panda's populations are rising, their conservation status is still uncertain, according to a study published Monday in Nature Ecology and Evolution. Researchers found the panda's habitat is smaller and more fragmented than it was when the bear was first put on the endangered species list in 1990.

Why it matters: Thanks in large part to China's efforts to restore the bamboo-eating bear's habitat, the panda population has been growing, and last year the bear was reclassified from endangered to vulnerable by the IUCN. But if that same habitat is becoming more fragmented, the improvements made might not be enough to support a growing population.

What they did: The researchers compared satellite images from 1976, 1988, 2001 and 2013.

  • From 1976-2001, the habitat increased by 4.9 percent, and has only gone up by 0.4% since 2001.
  • From 1976-2001, the average size of a roadless forest patch decreased by 24%, and grew 1.8% since 2001.

The bottom line: Moving pandas from the endangered to threatened list last fall was "a recognition of panda conservation success so far. But pandas are still facing threats, especially climate change. It does not mean that panda conservation should stop," study author Jianguo Liu told Ben Guarino of the Washington Post.

Breaking down the Tesla obsession

Tesla is the company of the moment — the prime exemplar of just about any big and important trend that you might care about.

Why it matters: Almost every reader of finance and business news will have at least one strongly-held opinion about Tesla. What you might not realize is just how widely those opinions range, and the degree to which they map onto much broader views of the world.

Gallup: Party preference swings dramatically in favor of Democrats

Americans' political party preferences have swung sharply from a 2-point Republican advantage in January to an 11-point Democratic advantage in July, according to Gallup's monthly averages of telephone polls in 2020.

The big picture: The dramatic shift is more a product of fewer people identifying as Republican or Republican-leaning (down 8% since January) than gains among those who identify as Democratic or Democratic-leaning (up 5%).

Nancy Pelosi: "I yearn for other Republican presidents"

House Speaker Nancy Pelosi (D-Calif.) called on President Trump Thursday to exercise "the full power" of the Defense Production Act to meet coronavirus equipment needs and accused him of engaging in a "massive dereliction of duty" by ignoring science during the pandemic.

What she's saying: "I yearn for other Republican presidents," Pelosi said at a press conference. "While we may have disagreed on many points, but at least we had a shared commitment to the governance of our country."
