BBC acknowledges ‘mistake’ in Boris Johnson editing

Entertainment
The BBC has said editing footage of Prime Minister Boris Johnson for a news bulletin was "a mistake on our part". The Prime Minister appeared on Question Time: Leaders Special on BBC One on Friday evening.The audience laughed when he was asked a question about how important it is for people in power to tell the truth.But the laughter and subsequent applause was absent from a cut-down version of the exchange on a lunchtime news bulletin the following day."This clip from the BBC's Question Time special, which was played out in full on the News at Ten on Friday evening and on other outlets, was shortened for timing reasons on Saturday's lunchtime bulletin, to edit out a repetitious phrase from Boris Johnson," the BBC said in a state...

DNA editing sees horned bull father six hornless calves

Technology
Scientists say they have developed an alternative to the practice of de-horning cattle after a genome-edited horned bull fathered six hornless calves.Researchers at the University of California spent two years studying the offspring after altering the DNA of the father, which they hoped would influence the characteristics of its young. Their work - detailed in the journal Nature Biotechnology - proved successful, with none of them developing horns but otherwise being perfectly healthy.It is hoped the technology could sound the death knell for the unpleasant practice of de-horning, which farmers carry out to protect themselves and other animals from potential harm.Study author Alison Van Eenennaam said genome editing offers a pain-free alternative by introducing a naturally occurring geneti...
Gene editing wipes out mosquitoes in the lab

Gene editing wipes out mosquitoes in the lab

Science
Researchers have used gene editing to completely eliminate populations of mosquitoes in the lab.The team tested their technique on the mosquito Anopheles gambiae, which transmits malaria.They altered part of a gene called doublesex, which determines whether an individual mosquito develops as a male or as a female. This allowed the Imperial College London scientists to block reproduction in the female mosquitoes.They want to see if the technology could one day be used to control mosquito populations in the wild.Writing in the journal Nature Biotechnology, Prof Andrea Crisanti and colleagues report that caged populations of Anopheles gambiae collapsed within 7-11 generations.Dr Crisanti said: "2016 marked the first time in over two...
CRISPR gene editing possible without using a virus, scientists say

CRISPR gene editing possible without using a virus, scientists say

Health
July 12 (UPI) -- Scientists have figured out a way to use genetically reprogram human immune cells without using viruses to insert DNA, as the CRISPR method of gene editing has traditionally required. In a study published recently in Nature, researchers at the University of California San Francisco show a new CRISPR technique involving T cells could help develop new and safer treatments for cancer, autoimmunity and rare inherited disorders. "This is a rapid, flexible method that can be used to alter, enhance, and reprogram T cells so we can give them the specificity we want to destroy cancer, recognize infections, or tamp down the excessive immune response seen in autoimmune disease," senior author Dr. Alex Marson, associate professor of microbiology and immunology, said in a press relea...
'Incredible' editing of life's building blocks

'Incredible' editing of life's building blocks

Science
Scientists have demonstrated an "incredibly powerful" ability to manipulate the building blocks of life in two separate studies.One altered the atoms in DNA to rewrite the human genetic code and the instructions for life. The other edited RNA, which is a chemical cousin of DNA and unlocks the information in the genetic code.The studies - which could eventually treat diseases - have been described as clever, important and exciting. Cystic fibrosis, inherited blindness and other diseases caused by a single typo in the genetic code could ultimately be prevented or treated with such approaches. Both studies were performed at the Broad Institute of MIT and Harvard. Base editingThe first, published in the journal Nature, developed tools called base editors. DNA is built out of the four bases: ad...
