Facebook CEO Mark Zuckerberg will testify at two Capitol Hill hearings this week over the Cambridge Analytica scandal, and we asked our tech reporter why that matters.

WASHINGTON -- Facebook CEO Mark Zuckerberg is testifying for the first time ever before Congress on Tuesday as he attempts to apologize for high-profile privacy breaches at the social media giant and convince doubtful lawmakers that he can fix the problem without government intervention. Zuckerberg is trying to restore public confidence after recent revelations that data from up to 87 million Facebook users was shared with Cambridge Analytica, a data mining firm used by the Trump campaign in the 2016 election. The information was shared without users' knowledge.

Engineers and chemists at Hiroshima University successfully used the same technology at the core of facial recognition to design chiral crystals. This is the first study reporting the use of this technology, called logistic regression analysis, to predict which chemical groups are best for making chiral molecules. Results were published in Chemistry Letters. Chirality describes the quality of possessing a mirror image to something else, but without the ability to superimpose it. Your left foot, for example, is a mirror of your right.

Another day, another sign that Tinder is ruining dating. This week's omen comes from a piece published over at the Outline on the digital pep talks dating apps like Tinder and Bumble are sending to their users. According to Renée Lynn Reizman, reminders to devote all your attention to the slot machine game of endless swiping are now coming with a little something extra. During a recent binge session of Netflix's Queer Eye, Reizman felt her phone vibrate and, "desperately in need of a little confidence boost," she hoped it was a new match from Tinder. While it was indeed a push notification from Tinder, it wasn't a match.

Killer robots could be on battlefields within a year if the UN fails to arrange an international treaty limiting their development. That's the claim of Professor Noel Sharkey, who says early wartime machines could cause mass deaths and they will not be able to tell the difference between enemies and civilians. His comments come as 120 United Nations member states meet this week at the Palais des Nations complex in Geneva to continue talks on the future challenges posed by lethal autonomous weapons system. Dr Noel Sharkey (right) is pictured here with Nobel Peace Laureate Jody Williams (left) campaigning for a ban on fully autonomous weapons. He believes an international treaty banning them is'vitally important' at a UN conference in Geneva this week Dr Noel Sharkey, a Professor of AI and Robotics as well as a Professor of Public Engagement at the University of Sheffield, told MailOnline that an international treaty banning the use of fully autonomous killer robots is'vitally important'.

Chinese leader Xi Jinping has pledged to lower car tariffs, improve intellectual property protection and open up the Chinese economy, addressing United States complaints in an escalating trade dispute. Xi made his remarks on Tuesday at the Boao economic forum on the southern island of Hainan. He did not mention US President Donald Trump directly. "China's door of opening up will not be closed and will only open wider," Xi said in his first public speech since the outbreak of trade tensions between China and the US. Also on Tuesday, it emerged that China filed a complaint against the US at the World Trade Organization (WTO) over steel and aluminium products tariffs imposed by Washington.

Fears automation will result in significant job losses may be overblown, according to new research from the OECD. While the research indicates as many as one in seven jobs could be lost to artificial intelligence (AI) automation, those numbers are lower than what had previously been predicted. In 2013, a paper by Oxford University academics Carl Frey and Michael Osborne, predicted that roughly 47 percent of jobs in the U.S. were at high risk of being automated. The paper, The Future of Employment: How Susceptible Are Jobs To Computerization, also showed wages and educational attainment had a strong negative relationship with an occupation's probability of computerization. In other words, the less a person earns and the less likely that person has received a higher education, the more likely their job will be computerized.

Complex statistics in Machine Learning worry a lot of developers. Knowing statistics helps you build strong Machine Learning models that are optimized for a given problem statement. This video will teach you all it takes to perform the complex statistical computations required for Machine Learning. You will gain information on statistics behind unsupervised learning, reinforcement learning, and more. You'll master real-world examples that discuss the statistical side of Machine Learning.

LG's artificial intelligence technology, ThinQ, first made its way to the Korean company's phones as part of the V30S. Now, the brand has confirmed that ThinQ is also coming to LG's flagship G-series, specifically the G7 that's debuting in New York on May 2nd and Seoul on May 3rd. According to the company's announcement, the G7 ThinQ's'Empathic AI' -- that's how LG describes its artificial intelligence, which it says is capable of human-like thinking to a certain extent -- is better than its predecessor's. We'll have to wait for the device's official launch to know how exactly it's better than the V30's, though. LG didn't expound on the new phone's features, but Israeli news site YNET got the chance to play with it a bit when it showed up in Barcelona during MWC.

Chinese tech and entertainment-oriented conglomerate Tencent Holdings is collaborating with the London-based health app developer Babylon Health, founded in 2013, to introduce medical chatbot AI capabilities into their solutions. While the press release from Babylon Health does not go into detail about the target scenario, Financial Times writer Aliya Ram suggests that the technology will directly go into Tencent's social messaging platform WeChat. No financial details on the deal have been disclosed. WeChat itself could be considered a hybrid of Facebook, WhatsApp, and Twitter from a functional point of view. Even though they are primarily used only in China, with their 1 billion monthly active users they can be considered as one of the world's most popular communication platforms.

When we think about artificial intelligence and the "world of the future," our vision is usually more Jetsons than Green Acres. But for Dr. Ranveer Chandra, a Principal Researcher in the Systems and Networking group at Microsoft Research, rural farms are the perfect place to realize the benefits of AI through what he calls precision agriculture, or data-driven farming. Today, in a wide-ranging interview, Dr. Chandra talks about how his research may eventually make your wi-fi signal stronger and your battery life longer, but also shares the story of how spending childhood summers with his grandparents in rural India inspired a line of research that could change the face of farming and help meet the food and nutrition needs of a growing global population. Ranveer Chandra: One of the latest projects I'm doing is Farm Beats. And for that, to actually see how well your research works, you need to be out there in a farm. I'm like, "What am I doing going out there in the farm in the middle of nowhere in this rain?" But on the other hand, just reminding yourself that if this research works, this is going to benefit so many farmers. It gives you that level of energy to keep going, to keep thinking about doing bigger things and not stopping where you are. A show that brings you closer to the cutting edge of technology research and the scientists behind it.

Host: Ranveer Chandra, welcome to the podcast, it's great to see you today. Ranveer Chandra: Yeah, thank you. I'm excited to be here. And it says on the website that you develop technologies that "expand the state of the art in computing." Ranveer Chandra: I come from a networking background.
