First human embryos edited in United States through "CRISPR" technology

CRISPR works as a type of molecular scissors that can selectively trim away unwanted parts of the genome and replace it with new stretches of DNA

They said it would be "irresponsible" to use gene editing technology in human embryos for therapeutic purposes.

The approach holds great potential to avoid many genetic diseases, but has raised fears of "designer babies" if done for less lofty reasons, such as producing desirable traits.

When reached by MIT Technology Review, Mitalipov declined to comment on the results, which he said are pending publication.

Successfully editing genes in human embryos could theoretically lead to scientists being able to cure any number of diseases, including cancer.

Previous reports of editing human embryos were all by scientists in China. Technology Review could not determine which disease genes had been chosen for editing.

State Dept.: Tillerson's Sudden 'Time Off' Not Sign He Intends to Quit
Tillerson returned to his home in Texas for a couple of days but was back in the office by Wednesday. "He recognises that. Secretary of Defense James Mattis is also out this week - according to the Pentagon , he is away on "personal travel".

A person familiar with the research says "many tens" of human IVF embryos were created for the experiment using the donated sperm of men carrying inherited disease mutations.

The OHSU researchers are said to have broken new ground, Reuters reports.

CRISPR works as a type of molecular scissors that can selectively trim away unwanted parts of the genome, and replace it with new stretches of DNA.

According to OHSU spokesperson Eric Robinson, the result of the peer-reviewed study are expected to be published soon in a scientific journal.

"It is proof of principle that it can work", an anonymous scientist familiar with the project told MIT. "I don't think it's the start of clinical trials yet, but it does take it further than anyone has before".

Six Cong MPs suspended from Lok Sabha for 'unruly behavior'
The six MP who have been suspended are Gaurav Gogoi , Adhir Ranjan Chowdhury, Ranjit Ranjan, Sushmita Dev, MK Raghav and K Suresh. The Opposition stood up in protest and threw paper all over and shouted slogans saying "Gunda Raj nahi chalega" in the House.

The US intelligence community past year labelled CRISPR a potential 'weapon of mass destruction'.

But in March this year, that academy and the American Medical Academy said in a new report that recent advances in the field "opened up a realistic possibility that deserves serious consideration". This effect, where some cells have a different genetic make-up to others is referred to as "mosaicism", an effect that experts warned would make germline engineering unsafe for humans.

When cellular machinery repairs the DNA break, it removes a small snip of DNA.

Somewhat prophetically, Perry's paper on the research, published at the end of 2014, said, "This or analogous approaches may one day enable human genome targeting or editing during very early development".

This is not the first time in the world this gene-editing technique has been used.
