Genetically Modified Embryos Represent 'Good Step to Improve Human Life'

"Revolutionary" gene editing technology is controversial because it presents the possibility of creating genetically modified humans, but it also has the potential to make a positive difference to human health, bioethicist Dr. Sarah Chan of the University of Edinburgh said.

A team of researchers at Oregon Health and Science University in Portland have become the first in the US to create genetically modified human embryos.

Since 2015, scientists in China have published three reports on the gene editing of human embryos, which caused an ethical storm and led to calls for an international moratorium on human genome editing amid fears they could be used to produce a baby.

However, the team led by biologist Shoukhrat Mitalipov, head of the Center for Embryonic Cell and Gene Therapy at Oregon Health and Science University, has gone even further than the Chinese researchers in editing the human genome, MIT Technology Review reported.

Researchers in both countries used the gene-editing technique CRISPR to change the DNA of a number of one-cell embryos. 

The scientists at Portland reportedly surpassed their Chinese colleagues because they edited the genomes of many more embryos and corrected defective genes that cause inherited diseases.

One of the ethical concerns about the gene editing of embryos is that they could potentially be implanted into a women's uterus. 

Dr. Sarah Chan, deputy director of the Mason Institute for Medicine, Life Sciences and Law at the University of Edinburgh, the fact that the embryos were destroyed is "very important."

"One of the concerns that is sometimes raised about gene editing in human embryos, is that one day it may be used to create genetically modified human beings. 

Now, various reports that have come out looking at the ethics of this issue have said that actually there are potentially useful applications of gene editing to prevent human inherited disease, but we are not at the point yet where we are confident to apply the technology to do that."

"So, while we are still investigating the scientific issues, while we are still trying to better understand the safety issues involved, I think it's very important that we make a distinction between research that is done in the laboratory and remains in the laboratory, versus any attempt to implant edited embryos which would be attempting to create genetically modified humans," Chan said.

While gene editing techniques such as CRISPR have the potential to cure inherited diseases in the future, scientists are still limited to trying to understand the diseases, before they can genetically edit a cure. 

In fact, the possibility of modifying DNA has been available for decades via the use of recombinant DNA technology, which allows the joining together of DNA molecules from different species. 

However, CRISPR is "revolutionary" because it provides a more efficient and precise way of targeting genes, making it less costly and time-consuming.

"We are now at the point where we are able to use gene-editing technology in many contexts at a lower cost, to do things better and more precisely. 

The reason that some people also say that makes it controversial is because it brings us closer to one day being able to use gene-editing technologies for human therapeutic applications, to use gene-editing technologies to cure disease."

"I suppose people say that's controversial because we would be interfering with the genome of humanity, but in my view anything that improves human health and welfare and makes people's lives better is a good step."

Armenian protesters block traffic, railways & airport as protest leader loses PM bid

Anti-government protesters disrupted traffic in Armenia’s capital, blocking railways and roads leading to Yerevan International Airport, after the parliament voted against opposition leader Nikol Pashinyan’s bid for interim PM.
Protesters managed to block streets connecting downtown Yerevan to residential districts, disrupting transportation in Armenia’s capital, footage from the scene shows. 
Yerevan’s metro system has also been paralyzed as demonstrators sit on the tracks, preventing trains from passing.
Meanwhile, protesters disrupted traffic on a road leading to Yerevan’s Zvartnots International Airport, located just 12km from the center of the city. 
Consequently, some passengers had to go the rest of the way on foot in order to catch their flights, according to Sputnik news agency.
Railway services have also been disrupted all across the country amid the demonstrations, a spokesman for South Caucasus Railways confirmed to Interfax. 
Some other highways, including the one connecting th…

Iran Killing Command: The use of firearms in dealing with protesters

The document you see on the image is the order of the commander of the Tehran repressive force to all the units based in the city.

Based on this agenda, the mercenaries of the corrupt government Islamic Republic of Iran have been allowed to use firearms in the event of any protest movement against people by the regime.
This is a murder command.
The repressive force of the law, known to the world's famous police and guardians, should protect the lives of its citizens, by freeing their mercenaries, they allow them to murder Iranians who are protesting the corruption in the government and you have the important message that if you come to the streets in protest of corruption and torture and massacre, we will kill you.
Because, according to criminal Khomeini, maintenance of the system is obligatory.
A corrupt government that is so hideous that spend billions of dollars from the national treasury and popular capitalto the suppression of its people and the countries of the region, must be ov…

ایران فرمان قتل : دستور استفاده از سلاح گرم در برخورد با معترضان

سندی که در تصویر میبینید دستور فرمانده نیروی سرکوبگر انتظامی تهران به همه یگانهای مستقر در این شهر است.
بر اساس این دستور کار ، مزدوران حکومت فاسد نظام جمهوری اسلامی اجازه یافته اند که درصورت بروز هرگونه جنبش اعتراضی از سوی مردم علیه رژیم ، از سلاح گرم استفاده کنند.
این دستور یک فرمان قتل است.
نیروی سرکوبگر انتظامی که به ظاهر و تعریف شناخته شده پلیس در سراسر جهان ، میبایست حافظ جان شهروندان باشد ، با آزاد گذاشتن دست مزدوران چکمه پوش خود انها را مجاز به قتل ایرانیان معترض به فسادهای موجود درلایه های حکومت میکنند و این پیام مهم را در خود دارد که اگر در اعتراض به  فساد و شکنجه و کشتار به خیابانها بریزید شما را خواهیم کشت.
چرا که به گفته خمینی دجال، حفظ نظام از اوجب واجبات است.
حکومت فاسدی که انقدر وقیح هست که میلیاردها دلار از خزانه ملی و سرمایه مردمی را صرف سرکوب مردم خود و کشورهای منطقه میکند باید سرنگون کرد.
اکنون چهل سال است که کشور ما به اشغال این ملایان جنایکتارخونخوار و اسلام تحمیلی در آمده است .
هنوز باورش برای برخی سخت است که درک کنند کشور ما به معنای واقعی کلمه از سوی بنیادگرایان الله…
