Street lamps may negatively impact pollination

Researchers in Switzerland found that pollination is negatively affected by artificial lighting, furthering the belief that the "human footprint can reverberate throughout an ecosystem," according to Nature.

A new study looked at how artificial lighting at night is affecting insects like moths, beetles, and others that spread pollen after dark. To test it, the scientists exposed a plot of cabbage thistle to street lamps, and found that those plots "had 62% fewer visitations from insects than plots situated in darkness." Essentially, lights could be driving away night-time pollinators, which "could lead to less fruit and fewer plants."

On the other hand, Jon Sadler, ecologist and biogeographer at the University of Birmingham, UK, said night-time pollinators being pushed into darker areas due to the lights "might actually enhance pollination in those places."

Why Trump added a streetfighter to his legal team

A new addition to President Trump's legal team — Joe diGenova, a former U.S. attorney who is well-known in Washington and has argued for the president on Fox News — reflects three White House realities.

The state of play: (1) The White House is digging in for a fight that looks to be longer and messier than officials had expected. (2) This is another example of the president responding to televised cues. Trump has spent most of his adult life in litigation, and obsesses about legal positioning in the same way that he is consumed by his press coverage. (3) It's another pugilistic voice at the table, and suggests that this weekend's attacks on Mueller won't be the last.

Facebook reaches a tipping point

Of all the news crises Facebook has faced during the past year, the Cambridge Analytica scandal is playing out to be the worst and most damaging.

Why it matters: It's not that the reports reveal anything particularly new about how Facebook's back end works — developers have understood the vulnerabilities of Facebook's interface for years. But stakeholders crucial to the company's success — as well as the public seem less willing to listen to its side of the story this time around.
