A new study shows there are 389 specific genetic signals involved in the timing of puberty — four times the amount previously known.

  • Key detail: The researchers identified rare variations in two genes that lower the age of puberty when inherited from the father but have no effect when inherited from the mother. The finding suggests there may be different evolutionary benefits to parents of puberty starting earlier or later in their children.
  • Methodology: Researchers from the University of Cambridge analyzed the genomes of 370,000 women from earlier studies.
  • What's next: The researchers also found genetic evidence that links earlier timing of puberty to a greater risk of some cancers — breast, ovary and endometrial cancers in women and prostate cancer in men — that are sensitive to sex hormones later in life. However, more research needs to be done to identify the exact mechanisms and extent of the increased risk.

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.
