This Holy Week, Christians worldwide are celebrating the life, death, and resurrection of Jesus Christ, whom they believe is fully man and fully God. It's a conviction that appears to flout logic but, amazingly, is wholly in line with the revelations of modern science. Scientists used to believe that waves and particles were opposite phenomena, each obeying a different set of rules. A stone, for instance, is particle-like; its shape and size remain the same whether it exists in outer space, water, or molasses. By contrast, ripples are wave-like; their shape and size depend critically on the medium through which they move.

Sure, most of us only have to deal with it once in a while, but for CNN foreign correspondent Will Ripley it's a frequent foe. "Blackout curtains and melatonin" are a must according to Ripley. "I take a lot of vitamins. You're staying in different hotels, you're eating different foods; you want to make sure that you stay healthy and have stamina for working around the clock." Since becoming the American cable news network's Tokyo bureau chief in March 2014, the 35-year-old Connecticut native has been sent to the Middle East twice, China around a dozen times and North Korea seven times.

Microsoft has apologised after a robot it made "tweeted wildly inappropriate and reprehensible words and images" that included support for Hitler and genocide. The company launched Tay, an artificially intelligent robot, on Twitter last week. It was intended to be a fun way of engaging people with AI – but instead was tricked by people into tweeting out support of Hitler and genocide, and repeated white power messages. Microsoft said that it had no way of knowing that people would attempt to trick the robot into tweeting the offensive words, but apologised for letting it do so. Microsoft said that it had launched Tay after success with a similar robot, XiaoIce, in China.

Grand Theft Auto 6 is on its way, according to a report. Developers Rockstar have begun work on the follow up to GTA 5, which was released in 2013 and is by many measures the most successful and expensive game in history, according to a report from TechRadar. The company hasn't yet settled on a location and it isn't clear exactly when the new game will be released. It might not be released for some years yet – GTA V came five years after its predecessor. The game is unlikely to be set outside of the US, according to the same report.

If venture capital and research funding are any indication, artificial intelligence will play a leading role in shaping our future. And few tech innovators in the private or public sector have been as prominent in defining that role as Andrew Ng, chief scientist at China's search giant Baidu. Ng has taught AI at Stanford, led the Google Brain project, founded online education pioneer Coursera, and just last year took his post at "China's Google" in hopes of figuring out how to teach computers to see and hear, and to do that for the world's most populous country. Small wonder why China represents such a huge opportunity for machine intelligence applications. Baidu is the world's fifth most trafficked website.

Grafting plants is hard work: It helps reduce stress on plants' roots and create sturdier crops, but it can really stress out farmers. Humans have to struggle to cut plants just the right way and bind them together. That's where a new robot comes in: With the help of steel "hands," it turns plant grafting from tedious art into swift science. Vegetable expert Richard Hassell and his team recently revealed a new robotic system that grafts more quickly and efficiently than a human ever could. They modified a Korean-manufactured robot to grab two plants, precisely slice the upper shoot of one and the root stock of the other, and clamp the two parts together so they can grow into a single plant.

KOCHI: Saarang Sumesh made robots on his own long before he started going to school. The seven-year-old Class II student of Choice School, Tripunithura, is the youngest maker of robots in the state and, probably, the youngest in the country as well. The Palluruthy native, son of Sumesh V S and Srijaya, started building complex machines like internal combustion engine models from the age of three. By four, he began building the LEGO NxT robot models and started making his own robot models - walking stick for the visually challenged, house-cleaning robot, robotic hand, tricycle, humanoid robot - by the time he turned five. Now, he learns and makes new Arduino projects using micro-control kit (electronic kit) and Raspberry Pi. ''When I got the Lego robotic kit I was thrilled to make robots out of it.

The resounding win by a Google artificial intelligence program over a champion in the complex board game Go this month was a statement -- not so much to professional game players as to Google's competitors. Many of the tech industry's biggest companies, like Amazon, Google, IBM and Microsoft, are jockeying to become the go-to company for A.I. In the industry's lingo, the companies are engaged in a "platform war." A platform, in technology, is essentially a piece of software that other companies build on and that consumers cannot do without. Become the platform and huge profits will follow.

Drone attacks killed eight men suspected of belonging to al Qaeda in southern Yemen on Saturday night, local residents said, as a U.S. campaign against the militant group goes on amid a wider civil war in the country. Two missiles hit the fighters who had gathered in courtyards in the villages of al-Hudhn and Naqeel al-Hayala, residents from the southern coastal province of Abyan told Reuters by phone. Al Qaeda in the Arabian Peninsula (AQAP) has taken advantage of a war pitting the Iran-allied Houthis against forces loyal to exiled President Abd-Rabbu Mansour Hadi to grab territory and operate more openly. The group has carried out attacks against the Yemeni state for years, plotted to blow up U.S.-bound airliners and claimed responsibility for the January 2015 attack in Paris on a French magazine that killed 12 people. The United States has kept up a drone campaign against the militants, although it evacuated the last of its military and intelligence personnel from Yemen in March last year.

SAN FRANCISCO – The world's largest drone maker has teamed up with the nation's largest thermal camera company to create ready-to-fly drones that can see in the dark. The drone maker is DJI, a China-based company that currently has about 70% of the world drone market. The camera is by FLIR Systems, a Wilsonville, Ore.-based thermal and infrared imaging company. The collaboration will produce drones that can be used in search-and-rescue, firefighting, security and surveillance. At a news conference Thursday, the companies showed video shot from one of the infrared-capable drones in which several people walking in a pitch black field at night looked like brightly lit light bulbs moving across the rough ground.
