Trump Doubles Down on Threats Against North Korea as Nuclear Tensions Escalate

Mr. Trump made his latest comments on North Korea during a pair of televised media events that covered a dizzying array of topics. He assailed Senator Mitch McConnell, the Republican leader, for not passing his legislative priorities, calling it “disgraceful” that the party’s health care plan failed by one vote and hinting that the leader should step down if he cannot do better. Mr. Trump also said he would declare the opioid epidemic a national emergency and defended his decision to bar transgender people from the armed forces, saying he was “doing the military a great favor.”In his first response to Russia’s decision to force the United States to slash its diplomatic staff in half, the president said he would thank President Vladimir V.

Trump’s ‘Fire and Fury’ Threat Raises Alarm in Asia

“We’re going to see a confrontation between the United States and North Korea that will be ferocious and strong and bloody,” said Cheng Xiaohe, an associate professor of international relations at Renmin University of China in Beijing. He called Mr. Trump’s language “explosive,” and said the threat and counterthreat had resulted in a new stage of confrontation.Mr. Cheng said that he was also puzzled by the timing of Mr. Trump’s remark, just days after the United Nations Security Council imposed the toughest economic penalties yet on North Korea for its nuclear and missile programs […]

All Eyes Are on Tillerson and North Korean Counterpart at Asean Meeting

On the other hand, Mr. Tillerson’s comments were accompanied by increased saber rattling from Washington directed at the North, with the United States testing an unarmed Minuteman III intercontinental ballistic missile in the Pacific and flying two strategic bombers over the Korean Peninsula. In addition, Vice President Mike Pence said the two nations would not hold direct talks.On Saturday, the United Nations Security Council imposed the toughest sanctions yet on Pyongyang over its continued testing of missiles and nuclear weapons.PhotoSecretary of State Rex W. Tillerson on Wednesday.

Bush’s National Security Council, said in an interview that Mr. Tillerson would want to show not only the North Koreans but the rest of the world that he was open to a dialogue with the North if only to prove that alternatives to tougher sanctions had been tried.“But I don’t think the North is interested in talking,” Mr. Cha said.

In Breakthrough, Scientists Edit a Dangerous Mutation From Genes in Human Embryos

“We’ve always said in the past gene editing shouldn’t be done, mostly because it couldn’t be done safely,” said Richard Hynes, a cancer researcher at the Massachusetts Institute of Technology who co-led the committee. “That’s still true, but now it looks like it’s going to be done safely soon,” he said, adding that the research is “a big breakthrough.”“What our report said was, once the technical hurdles are cleared, then there will be societal issues that have to be considered and discussions that are going to have to happen. Now’s the time.”Scientists at Oregon Health and Science University, with colleagues in California, China and South Korea, reported that they repaired dozens of embryos, fixing a mutation that causes a common heart condition that can lead to sudden death later in life.If embryos with the repaired mutation were allowed to develop into babies, they would not only be disease-free but also would not transmit the disease to descendants.The researchers averted two important safety problems: They produced embryos in which all cells — not just some — were mutation-free, and they avoided creating unwanted extra mutations.“It feels a bit like a ‘one small step for (hu)mans, one giant leap for (hu)mankind’ moment,” Jennifer Doudna, a biochemist who helped discover the gene-editing method used, called CRISPR-Cas9, said in an email.Gene Editing in EmbryosScientists tried two techniques to remove a dangerous mutation. In the first, genetic “scissors” were inserted into fertilized eggs. The mutation was repaired in some of the resulting embryos but not always in every cell. The second method worked better: By injecting the “scissors” along with the sperm into the egg, more embryos emerged with repaired genes in every cell.FIRST TECHNIQUEWhen gene-editing components were introduced into a fertilized egg, some embryos contained a patchwork of repaired and unrepaired cells.Gene-editingcomponents insertedafter fertilizationCell withunrepairedgeneMaternal DNAMutationSpermPaternal DNACell withrepairedgeneOocyteFertilized cellMosaicism inlater-stage embryoNEW TECHNIQUEWhen gene-editing components were introduced with sperm to the egg before fertilization, more embryos had repaired mutations in every cell.Gene-editing componentsinserted together with sperm,before fertilizationIn 42 of 58embryostested, allcells wererepairedUniformlater-stage embryoFIRST TECHNIQUEWhen gene-editing components were introduced into a fertilized egg, some embryos contained a patchwork of repaired and unrepaired cells.Gene-editingcomponents insertedafter fertilizationMaternal DNAMutationPaternalDNASpermOocyteFertilizedcellCell withunrepairedgeneCell withrepairedgeneMosaicism inlater-stage embryoNEW TECHNIQUEWhen gene-editing components were introduced with sperm to the egg before fertilization, more embryos had repaired mutations in every cell.Gene-editingcomponents insertedtogether with sperm,before fertilizationIn 42 of 58embryostested, allcells wererepairedUniformlater-stage embryo“I expect these results will be encouraging to those who hope to use human embryo editing for either research or eventual clinical purposes,” said Dr. Doudna, who was not involved in the study.Continue reading the main storyMuch more research is needed before the method could be tested in clinical trials, currently impermissible under federal law. But if the technique is found to work safely with this and other mutations, it might help some couples who could not otherwise have healthy children.Potentially, it could apply to any of more than 10,000 conditions caused by specific inherited mutations.

White House Memo: Dropping the Bluster, Trump Revives Banter With Reporters

But this is hardly the view most people have of a president who built his populist appeal on contempt for the mainstream media; who thundered on Inauguration Day, “This American carnage stops right here”; and who told supporters on his 100th day in office, “If the media’s job is to be honest and tell the truth, the media deserves a very, very big fat failing grade.”Continue reading the main storyIn some ways, Mr. Trump has reversed the usual dichotomy between the public and private president.“One of the great differences between Trump and more successful politicians, like J.F.K. and F.D.R., is that they would vent their spleen in private, but in public, they would project a more humorous and civilized face,” said Robert Dallek, a presidential historian.John F. Kennedy, he said, canceled the White House’s subscriptions to The New York Herald Tribune out of pique at its coverage, even as he wooed and won over reporters. Mr. […]
