Scientists edit human embryos for first time in the U.S.

Researchers in Oregon have become the first in the U.S. to edit the genome of human embryos, MIT Technology Review reports.

  • Shoukhrat Mitalipov of Oregon Health and Science University and his team reportedly used the gene-editing technique CRISPR to change "the DNA of a large number of one-cell embryos" and to target a disease-related gene.
  • Per Tech Review: "Although none of the embryos were allowed to develop for more than a few days — and there was never any intention of implanting them into a womb — the experiments are a milestone on what may prove to be an inevitable journey toward the birth of the first genetically modified humans."
  • Why it matters: The goal is to see whether genes that cause inherited diseases can be corrected. Three previous studies on editing embryos, which took place in China, found errors from CRISPR and that the edited changes were only seen in some of an embryo's cells. Mitalipov and his colleagues are believed to have shown both of those effects can be avoided.

Clyburn: Sanders' "socialist" label will be "extra burden" in House races

House Majority Whip Jim Clyburn (D-S.C.) said on ABC's "This Week" Sunday that Sen. Bernie Sanders' identification as a democratic socialist may be an "extra burden" in down-ballot House races if he were to win the Democratic nomination.

Why it matters: Clyburn's comments echo fears from many establishment Democrats, who worry the House majority they won in 2018 by taking moderate seats carried by President Trump could be at risk with Sanders at the top of the ticket.

White House national security adviser Robert O'Brien repeatedly rejected on ABC's "This Week" an assessment from a congressional briefing led by the Office of the Director of National Intelligence that Russia is interfering in the 2020 election to help President Trump get re-elected.

Why it matters: The report put the Trump administration under fresh scrutiny in regard to steps it has been taking to combat the kind of interference that the U.S. encountered in 2016.

Italy becomes site of largest coronavirus outbreak outside of Asia

Data: The Center for Systems Science and Engineering at Johns Hopkins, the CDC, and China's Health Ministry. Note: China numbers are for the mainland only and U.S. numbers include repatriated citizens.

The novel coronavirus has spread to more nations as South Korea and Italy step up emergency measures in their countries amid rising case numbers on Sunday.

The big picture: COVID-19 has killed at least 2,462 people and infected almost 79,000 others, mostly in mainland China. South Korea increased the infectious disease alert to red, the highest possible, as its case numbers jumped to 602 and the death toll to five. Italy's government announced emergency measures as it confirmed a spike from three to 132 cases in matter of days, making it the largest outbreak outside of Asia.
