‘Impeach President Bannon’ street art protest takes aim at Trump’s controversial chief strategist

‘Impeach President Bannon’ street art protest takes aim at Trump’s controversial chief strategistA sign protesting “President Bannon” is seen in San Francisco. “Impeach President Bannon” posters were spotted in Washington, New York City and several other major cities on Sunday, part of a Presidents’ Day weekend demonstration against President Trump’s controversial White House chief strategist and senior adviser, Steve Bannon. “No one voted for Steve Bannon,” the California-based organizers of the protest wrote in an email to Yahoo News.

‘I was given that information; I don’t know’: 12 standout quotes from Trump’s marathon press conferenceOn Thursday, President Trump held a press conference in the White House East Room that ran for more than an hour. Here are a few of the more memorable quotes from the president. This was the president’s defense of former National Security Advisor Michael Flynn, who resigned Tuesday night.

Genetically-Modified ‘Surrogate Hens’ Could Lay Eggs of Rare Chicken Breeds, Scientists Say

In an effort to preserve rare varieties of chicken breeds and diversify the chicken gene pool, scientists at the University of Edinburgh’s Roslin Institute have come up with a plan to breed genetically-modified chickens designed to act as surrogates that would be capable of laying eggs from any rare breed. Such rare breeds include the Nankin, Scots Dumpy and Sicilian Buttercup. The Guardian reports: The surrogacy technique, which places a new, mind-bending twist on the classic chicken or egg question, involves first genetically engineering hens to be sterile. This is done by deleting a gene, called DDX4, that is required for the development of primordial follicles (the precursors to eggs) meaning that the surrogate hens will never lay eggs that are biologically their own. The next step will be to transplant follicles from rare birds into the surrogate (this is done before the surrogate chick is hatched from its own egg), meaning it would go on to lay eggs belonging to entirely different breeds of chicken. Given that the hens would also need to be artificially inseminated with sperm from the same rare variety, the approach may appear unnecessarily convoluted. Why not just breed the rare birds the normal way? The scientists’ ultimate goal is to create a gene bank of chicken breeds preserved for posterity, and since primordial follicles can be frozen efficiently, while eggs cannot, the surrogacy technique serves an essential work-around. Mike McGrew, who is leading the project and is the first author on a paper on the work published this week in the journal Development, predicts that the surrogates will be able to lay eggs from any breed, including chicken’s wild predecessor, the red junglefowl, but he is doubtful about whether it will work efficiently across species — it is not likely that the surrogate hens will be giving birth to eagle chicks, for instance. Richard Broad, a field officer for the Rare Breeds Survival Trust, agreed that rare chickens could be a source of valuable genetic variation, potentially carrying variants that would provide resistance against new forms of avian flu. At present, the team is focused on chicken breeds, but expects the technique to work to preserve rare varieties of ducks, geese and quail.

ISRO Makes History, Launches 104 Satellites With Single Rocket

neo12 writes: Indian Space Research Organization (ISRO) made history by launching 104 satellites in a single launch. The lift-off of PSLVC 37 at 9.28 am from Sriharikota was a perfect one. In 28 minutes, all 104 satellites were successfully placed into the Earth’s orbit. 101 of the 104 satellites belong to six foreign countries, including 96 from the U.S. and one each from Israel, the UAE, the Netherlands, Switzerland and Kazakhstan. According to Times of India, “Russian Space Agency held a record of launching 37 satellites in one go during its mission in June 2014. India previously launched 23 satellites in a single mission in June 2015.”
