More than 4,000 police officers have been deployed to London, as crowds start to gather for two rival protests in the capital. Police will use drones, police horses and dogs and have armoured vehicles on standby. Officers will also manage a so-called sterile zone between the Unite the Kingdom march, organised by far-right figure Tommy Robinson, and a pro-Palestinian demonstration. The Metropolitan Police has called it one of the most significant policing operations in years. In addition to the protests, tens of thousands of football fans are expected at Wembley Stadium for the FA Cup Final on Saturday afternoon.

These are just a few of the cutting-edge innovations showcased this week for the most elite military forces in the world. The annual four-day Special Operations Forces Industry Conference (SOFIC) kicked off earlier this week, packed with options to give fighting forces technological advantages they can use against their enemies. Defense officials from the U.S. and its allies will be exploring the conference, scouring for the best advanced technology. Groups like the Army Delta Force, Green Berets and Rangers as well as Navy SEALs, Marine Raiders and Air Force PJs all will use some of this technology. An annual collaboration between the U.S. Special Operations Command (SOCOM) and the National Defense Industry Association, SOFIC is expected to have more than 400 companies from all around the world.

Mashable kicked off the year by doing what we always do: Flying to Las Vegas and scouring CES, the year's largest tech show, for the latest gadgets and tech trends. As expected, AI, dominated the show, with tons of new products adding Amazon Alexa support. The weirdest one might have been LG's Smart InstaView refrigerator. Do you really need Alexa in your fridge? We also saw a boatload of self-driving smart cars and futuristic car technology. Noteworthy appearances came from Faraday Future, which finally showed off its high-tech FF 91 and Toyota's Concept-i UX car with built-in Yui digital assistant.
