Earlier this year, a team of Chinese researchers at Guangzhou Medical University succeeded at using CRISPR to edit the genes of some normal human embryos. It's like using a molecular scissors to cut and paste DNA, and is much more precise than some types of gene therapy that can not ensure that desired changes will take place exactly where and as intended.
CRISPR-Cas9 is a tool for making precise edits in DNA, discovered in bacteria.
In theory, the technique could also be used to create "designer" babies with specific desirable qualities, such as eye color or strength, and possibly even greater intelligence, a prospect that has sparked a lively ethical debate in the scientific community and beyond.
Technology that allows adjustment of genes in a human embryo has been used for the first time in the United States.
Mitalipov's team worked with human embryos produced by sperm from men with a genetic mutation, the report said, noting they were of "clinical quality".
"It is proof of principle that it can work", an anonymous scientist familiar with the project told MIT. That makes gene-editing unsafe. "But it's only a first step", she said. If such a genetically modified child were born, they would pass on the edited changes in their DNA to subsequent generations.
Mitalipov declined to comment on the results which, he said, are pending publication.In the process termed "germline engineering", the scientists demonstrated that it is possible to safely and efficiently eradicate or correct defective genes that cause inherited diseases like the blood condition beta-thalassemia.
Some countries have already signed a convention prohibiting the practice - and religious groups have voiced their concern. The research, however, was limited to the lab and the embryos were not meant to be implanted into the womb.
The report also offered qualified support for the use of CRISPR for making gene-edited babies, but only if it were deployed for the elimination of serious diseases.
Hank Greely, director of Stanford University's Center for Law and the Biosciences, called CRISPR "the most exciting thing I've seen in biology in the 25 years I've been watching it", with tremendous possibilities to aid human health. Or are we going to engage democratic deliberation to determine if this should be done, and if so, what the parameters are?
Officials say they will not release the identities of the victims or where they're from until their families can be notified. Mexican officials were working with USA authorities to identify the dead, the country's foreign ministry said .
Experts have warned in recent months that tougher immigration policies could make it more hard to stop human trafficking. The police chief said the group included children, but later told CNN that the eight dead were adult men.
A finished road could provide Chinese troops with an avenue to sever India's access to its northeastern states. India said on Thursday that there should be freedom of navigation in the South China Sea.
Automakers were also among the losers with Hyundai Motor, the No. 1 automaker, falling 1.01 percent to end at 146,500 won. The previous record was set in the third quarter of 2013, when Samsung's operating profit hit 10.1 trillion won.
When Microsoft first showed off the console, the company said pre-orders would be delayed until it had been certified by the FCC. Microsoft has been a bit mum on when pre-orders will begin, which has led to some gamers tweeting their questions.
More than 3,800 fire personnel have been assigned to the fire. "This fire has really devastated the area, business is just flat". Rangers warned visitors with respiratory problems to be mindful of the smoky haze over the park's landmark Half Dome rock face.
Meanwhile, Shiromani Akali Dal MP Chandu Majra sought answers from the government on the issue in Parliament on Monday. Iraqi forces liberated Mosul after 266 days of fierce battles, ending three years of Islamic State rule.

E-cigarettes help people quit smoking, study says
To assess e-cigarette use and associated changes in population smoking cessation in the U.S., researchers analyzed data from U.S. Results showed that 65 per cent of e-cigarette users tried to quit, versus 40 per cent of smokers who didn't vape.
