Coral reef fish take note of what others are eating, a behavior that can affect sensitive reef environments. Scientists from the University of California-Davis and Princeton studied fish grazing around coral reefs in French Polynesia and found that fish decide to feed on algae if they see lots of other fish in the same place. But if there aren't any other fish nearby, they take it as a sign that predators are close and avoid that section of the reef.

Why it matters: Fish keep the growth of algae, which can harm coral reefs, in check. Overfishing threatens that balance not just because there are simply less fish consuming algae but because fish interpret the presence of fewer fish as a risk when there may not be one. The researchers suggest the newly-revealed link between the social interactions of fish and how food and energy flow through the reef should inform how these sensitive environments, distressed by climate change, are managed.

China-Iran deal envisions massive investments from Beijing

China and Iran have negotiated a deal that would see massive investments flow into Iran, oil flow out, and collaboration increase on defense and intelligence.

Why it matters: If the proposals become reality, Chinese cash, telecom infrastructure, railways and ports could offer new life to Iran’s sanctions-choked economy — or, critics fear, leave it inescapably beholden to Beijing.

House Judiciary Committee releases transcript of Geoffrey Berman testimony

The House Judiciary Committee on Monday released the transcript of its closed-door interview with Geoffrey Berman, the former top federal prosecutor in Manhattan who was forced out by Attorney General Bill Barr last month.

Why it matters: House Democrats have seized on Berman's testimony, in which he claimed the attorney general sought to "entice" him into resigning so that he could be replaced by SEC chairman Jay Clayton, to bolster allegations that the Justice Department has been politicized under Barr.
