The discovery of the gene-editing technology CRISPR came, in part, from Jennifer Doudna, a biochemist at the University of California, Berkeley. “It’s very profound,” she told NBC News. “It means that we can control human evolution now.”
With collaborator Emmanuelle Charpentier, Doudna was able to harness a curiosity in the DNA of certain bacteria and help turn CRISPR into the world’s most accessible gene-editing technology. The discovery is detailed in Doudna’s new book titled “A Crack in Creation.”
In the book, Doudna says that the days of costly, complicated processes to edit DNA are over. We’re now in an age of CRISPR, and it’s a profoundly simple technique. Doudna compares CRISPR to word-processing software that allows someone to correct a typo in a hefty document.
Mark Zuckerberg has spent the last dozen years making sure you know what your friends’ babies look like and what your high school friends think about politics.
And, of course, transforming media and politics by presenting news and opinion — true and fake — to billions of people around the world.
Now the Facebook CEO is acknowledging that connecting people online isn’t enough.
.
“We used to have a sense that if we could just do those things, then that would make a lot of the things in the world better by themselves,” Zuckerberg told CNN Tech. “But now we realize that we need to do more too. It’s important to give people a voice, to get a diversity of opinions out there, but on top of that, you also need to do this work of building common ground so that way we can all move forward together.”
The United States and Iraq said ISIS blew up a historic mosque in Mosul that was the ideological heart of the terror group and the birthplace of its self-declared caliphate.
ISIS, through its news agency, said US warplanes were responsible for the loss late Wednesday of the Great Mosque of al-Nuri and its leaning minaret.
.
US officials told CNN the ISIS claim was “1,000% false.”
raq Prime Minister Haider al-Abadi said the ISIS act amounts to “an official announcement of their defeat.” His military commanders said militants blew the mosque up after troops closed in.
It sounds wild. But the idea that we live in a multiverse — a cosmos where an infinite number of universes exist beside our own — is no longer confined to science fiction. It’s a respectable theory among scientists, so much so that some are on the hunt for proof of a nearby universe.
Now, scientists might be one step closer. A study recently submitted to “Monthly Notices of the Royal Astronomical Society” actually places the multiverse theory on firmer ground. Ruari Mackenzie, a graduate student at England’s University of Durham, took a deeper look at a region in the sky that’s so frigid and so large that most scientists don’t think it can be a statistical fluke. Instead, some astronomers think this so-called “cold spot” is an optical illusion produced by a lack of intervening galaxies. But Mackenzie and his colleagues found that those galaxies are no less dense than anywhere else in the universe, disproving that theory.

For the first time ever, scientists have captured a single DNA molecule replicating on video — and it’s changing the way we think about the entire process. One of the most surprising findings is how much randomness characterizes the process.
“It’s a different way of thinking about replication that raises new questions,” Stephen Kowalczykowski, molecular genetics professor at University of California, Davis, said in a press release. “It’s a real paradigm shift, and undermines a great deal of what’s in the textbooks.”
The researchers watched replicating DNA from E. coli bacteria. The first step in the process always sees the double helix “unzipping” into two strands — a “leading strand” and a “lagging strand.” Each of these become a template for a new strand that is made to match it, leaving two complete DNA molecules when the process has reached the end. The researchers wanted to measure how fast the enzyme machinery moving along the different strands in opposite directions worked.
When a bullet pierces flesh, it ripples through the tissue in a chaotic fury. It will inevitably shred nerves, blood vessels and muscle. It might fracture bone. Deposit in an organ. Or zip out through another body part, leaving blood to ooze from the open pit.
Sometimes, the bullet carves a fatal path: About 36,000 Americans were killed by a firearm in 2015, according to the Centers for Disease Control and Prevention. The majority of those deaths — almost two-thirds — were the result of suicide and involved mostly men 45 and older taking their own lives. Another third of deaths were linked to homicides, while the remaining sliver involved accidental shootings.
Most often, however, the bullet fails to kill: In 2015, nearly 85,000 people who were treated in emergency rooms survived. For those gunshot victims, their wounds were likely non-life-threatening — in either the legs or arms, National Institutes of Health data show. A smaller percentage of assaults or accidental shootings involved getting struck in the head or neck, with only about one-third of those victims surviving long enough to reach a hospital.
Dominique Heaggan-Brown, the former Milwaukee police officer who fatally shot Sylville Smith during an August 2016 foot chase, was found not guilty of first-degree reckless homicide on Wednesday.
Members of Smith’s family could be heard crying in court as the verdict was read. Smith’s death sparked days of unrest in Milwaukee.
.
Shortly after the verdict, Smith family attorney David Owens said they had filed a lawsuit against Heaggan-Brown and the city. The suit claims Milwaukee kept the former officer on the job despite a “pervasive pattern of excessive force and misconduct,” including at least 16 “use of force” incidents.
Mars and the Earth may have more in common than we thought. NASA just revealed photos of Mars taken by its Mars Reconnaissance Orbiter. The images look strikingly similar to planet Earth.
The MRO, which has sent thousands of vibrant images back to scientists, has documented everything from dust storms to mineral hills since its launch nearly 12 years ago. The landscapes are somewhat like red deserts or canyons. “Earth has more in common with Mars than you might think,” NASA wrote in a recent video uploaded to YouTube.
MRO is used to better understand materials, subsurface water, dust and weather on Mars, according to NASA’s website. It’s also great at supplying us with gorgeous photos of the red planet.
The robots may soon take one of the best jobs of them all: whiskey taste-testing.
Scientists recently designed a set of sensors, playfully called a “tongue,” that can analyze the chemical composition of whiskey and tell us about its age, country of origin and malt status.
The sensors are made of glowing solutions that change brightness when drops of whiskey are added to them. The result ultimately indicates different properties of the liquor — which may be noticeable to a whiskey master, but without the chemical certainty.
American college student Otto Warmbier only intended to spend five days sightseeing in North Korea in 2016.
Instead, he spent 17 months there in detention where his family believes he was tortured into a vegetative state.
.
On Monday, less than a week after returning to the United States with severe brain damage, his family announced Warmbier had “completed his journey home.” The 22-year-old died Monday afternoon in Cincinnati, Ohio, with his family at his side.
In the world, human beings are facing various problems. People who are full of greed, anger, and ignorance are seen to be fighting with each other in words and deeds. As the fighting continues, various problems such as civil wars, wars of aggression, and wars of aggression are occurring. As world peace is being destroyed, humans are facing unbearable problems. Innocent children and women are not getting the rights they deserve and deserve. I can't think of one thing every time. What is it? The United Nations. If we look at the responsibilities and duties of the United Nations, I think it is not suitable for solving the problems that are happening in the world today. In fact, the United Nations and the World Security Council, such an organization must rule the world, must be able to give orders, and must have various ways to obey orders. There must be no organization that can influence more than that organization. There should be experts from each country. They can even dominate the superpowers like the US, China, and Britain. Only then will global peace be achieved quickly. Now, if a country with power develops more militarily, economically, or socially than its own country, then powerful countries will jealously seek out enemies and wage war. Or they will attack with fighter jets. In this, innocent people are losing their lives. No one understands the value of a life. You should think about how to achieve global peace by controlling these. If the US continues to be the permanent president of the UN, world peace will never be achieved. If you think carefully, no one sees that they are working for the common good, but for their own benefit, for the benefit of their own country. The permanent president of the UN and the Security Council has rejected this, As a young Rohingya, I have come to realize that only by electing the president and secretary from among the countries in the world through a secret ballot system and governing the world fairly can we achieve global peace. The United Nations and the Security Council are organizations in which any country must govern, give orders, and make them obey their orders. For example, only when a defendant is tried in court can we hold the leaders of the countries in check and control them, can we achieve global peace smoothly. Otherwise, it will not be easy for powerful countries to use various excuses to end this war every year, every year, for the benefit of themselves and their countries. No country's leaders pay any attention to the words of the United Nations and the Security Council. If we look at it in practice, look at the Rohingya issue. Myanmar is a small country. Even that country has been under siege for 8 years. What action can be taken? Why is the UN and the Security Council Powerless? Without such Power, how can the organization bring about global peace? Everyone should think about it. Whether there is a veto or a strong one, all countries in the world can only achieve global peace if they are subject to the UN and the Security Council. Seek peace in the quiet embrace of nature. Peace is an indispensable need of the human race. It is not as if one person can kill another person, and it is as if one country can attack another country, but instead of trying to build peace, we must try to destroy the peace now, and the world is getting hotter and is on the verge of collapse. I especially appeal to all the world experts to urgently try to bring about peace in all parts of the world. Mr, Noor Muhamed Arkhan Rohingya Youth Myanmar
