We can't deny that artificial intelligence assistants have come flooding in the market lately. You have Amazon's Alexa, Google Assistant, Apple's Siri, and Microsoft Cortana. Finnish tech company Nokia is also getting in on the AI Assistant bandwagon. Its name is Multi-purpose Intuitive Knowledge Assistant or simply MIKA. The announcement for Nokia's new AI voice assistant comes a month before Nokia's expected appearance at the Mobile World Congress.

When a May 2016 crash killed the person operating a Tesla Model S driving in Autopilot mode, advocates of autonomous vehicles feared a slowdown in development of self-driving cars. Instead the opposite has occurred. In August, Ford publicly committed to field self-driving cars by 2021. In September, Uber began picking up passengers with self-driving cars in Pittsburgh, albeit with safety drivers ready to take over. October saw Tesla itself undeterred by the fatality.

A soft robotic sleeve placed around the heart in a pig model of acute heart failure. The actuators embedded in the sleeve support heart function by mimicking the outer heart muscles that induce the heart to beat. An international team of scientists has developed a soft robotic sleeve that can be implanted on the external surface of the heart to restore blood circulation in pigs (and possibly humans in the future) whose hearts have stopped beating. The device is a silicon-based system with two layers of actuators: one that squeezes circumferentially and one that squeezes diagonally, both designed to mimic the movement of healthy hearts when they beat. Heart failure affects 41 million people worldwide.

WASHINGTON – It's been described as the greatest burden any commander in chief must bear. Just days into his young presidency, a U.S. service member has died in military action authorized by Donald Trump. It's the first known combat death of a member of the U.S. military since Trump took the oath of office on Jan. 20 and underscores the gravity of the decisions he now makes. Three service members were also wounded Sunday during the firefight with militants from al-Qaida in the Arabian Peninsula's branch in Yemen. The raid left nearly 30 others dead, including an estimated 14 militants.

WASHINGTON (AP) -- It's been described as the greatest burden any commander in chief must bear.

Over the past decade, the stellar growth of Indian economy has been challenged by persistently high levels of inflation, particularly in food prices. The primary reason behind this stubborn food inflation is mismatch in supply-demand, as domestic agricultural production has failed to keep up with rising demand owing to a number of proximate factors. The relative significance of these factors in determining the change in food prices have been analysed using gradient boosted regression trees (BRT), a machine learning technique. The results from BRT indicates all predictor variables to be fairly significant in explaining the change in food prices, with MSP and farm wages being relatively more important than others. International food prices were found to have limited relevance in explaining the variation in domestic food prices. The challenge of ensuring food and nutritional security for growing Indian population with rising incomes needs to be addressed through resolute policy reforms.

In recent days there has been extensive discussion of claims that Donald Trump owes his victory in the recent Presidential election at least in part to Big Data. This is something of a surprise to observers since - although it has been widely reported that Hillary Clinton and, before her, Barack Obama had recruited hordes of bright young computer scientists to drive their campaigns - it had been assumed that Trump relied on more traditional means of connecting with voters. Indeed, the man himself has insisted he used his "gut" in campaigning and regarded Big Data as over-rated. At the heart of the matter is the role of Cambridge Analytica, a company that claims to use expertise in behavioral change and data science to "offer unparalleled audience insight and engagement services and products". What this translates into is using extensive detailed information - the company says it collects up to 5,000 "data points" on 220 million Americans - alongside psychological insights to model target audiences and predict the behavior of like-minded individuals.

A U.S. military service member was killed Sunday during a raid against al-Qaida militants in central Yemen that also left nearly 30 others dead, including women and children. The loss of the service member is the first-known combat death of a member of the U.S. military under President Donald Trump. "Americans are saddened this morning with news that a life of a heroic service member has been taken in our fight against the evil of radical Islamic terrorism," Trump said in a statement. The U.S. has been striking al-Qaida in Yemen from the air for more than 15 years, mostly using drones, and Sunday's surprise pre-dawn raid could signal a new escalation against extremist groups in the Arab world's poorest but strategically located country. An al-Qaida official and an online news service linked to the terror group said the raid left about 30 people dead.

Sylvester Kaczmarek is an award-winning entrepreneur and product leader with more than a decade of international, quality-driven IT industry experience. One of the most popular shows on television 30 years ago was "The A-Team" -- the story of five rogue military commandos who teamed together to form an elite fighting unit. Now, a generation later, DARPA and the U.S. military are in search of a new "A-Team" -- only this team won't be comprised of just humans, it will include a few machines, as well. A-team refers to "agile team," which DARPA refers to as hybrid teams of humans teamed with intelligent machines. What DARPA recognizes is that intelligent machines are not just "agents" carrying out the simple commands of humans, but rather are part of an "intelligent fabric" that dynamically evolves over time. The obvious use case for these A-teams, of course, is in the military sphere.
