Google said on Wednesday it would offer an audio-only option on its Duo video calls service to help users communicate using poor-quality connections, and was adding a feature to permit file sharing in group chats on its Allo messaging App. The company launched Google Duo in August, providing video calls for users on Android and iOS, pitting it against Apple Inc's FaceTime, Microsoft Corp's video-calling app Skype and Facebook Inc's Messenger. Google, owned by Alphabet Inc, said audio-only calls on Duo would be available from Wednesday in Brazil, and would be rolled out to users around the world in the coming days. The audio-only calls would work well on all connection speeds and be data efficient, Google Vice President for Product Management Mario Queiroz said in a blog post after he announced the moves at a Google conference in Sao Paulo. In response to requests from users in countries like Brazil, Google said that Android users everywhere would be able to share documents and other files (.pdf, .docs,

Located at the mouth of the River Plate, Argentina's capital Buenos Aires is subject to torrential rain. With an ageing infrastructure and nine subterranean rivers, the deluge can turn into floods. Clogged drains have been responsible for property damage, even lost lives. To track water flow the city has installed sensors across the sewage system, measuring speed and level of water. This information is combined with weather data and even garbage vehicle sensors.

Wednesday's Google Doodle features a lot of firsts: The first Turkish woman to compete in the Olympics. Those heroes would be Halet Çambel and Ada Lovelace, respectively. The illustration, marking International Women's Day 2017, also features the first woman in Argentina to receive a medical degree, Cecilia Grierson, and Korea's first female judge, Lee Tai-young. According to Google, the search image depicts a girl whose grandmother is sharing the life stories of 13 exceptional women in history around the world. Also among the inspirational women featured are Ida Wells, the American journalist and civil rights activist, Lotfia El Nadi, Egypt's first female pilot, and Miriam Makeba, the South African singer and civil rights activist.

It's time to get airdropped into Ghost Recon: Wildlands and Bolivia isn't going to welcome you with open arms. While you're getting acclimated to the lush-yet-treacherous provincial landscapes and trying not to get killed by the Santa Blanca cartel or UNIDAD (the local military police), we've got a few tricks for staying alive and navigating the terrain effectively. There are a myriad of transportation options scattered throughout the provinces. Each has its merits and is useful in different scenarios, depending on where you are and what you're trying to accomplish. Regular Vehicles (cars, trucks, civilian SUVs): In the valleys and hills of Itacua, your best bet is usually hopping into whatever vehicle is available at the rebel checkpoints.

It's official: driverless cars have hit the race tracks. Roborace, the autonomous race car maker, had its two self-driving'DevBots' compete against each other at the Formula E Buenos Aires ePrix. The race didn't go without its own surprises: One car had to dodge a random dog that ended up on the race track, and the other ended up hitting a barrier, unable to finish the race. Roborace's self-driving car races will take place at Formula E events throughout 2017. All cars competing will be made identically.

Artificial intelligence has made some great developments toward speeding up cancer diagnosis so far in 2017. Last month it was announced that AI from Sophia Genetics was helping to accelerate patient diagnosis across Latin America. Earlier this year researchers at Stanford University developed a deep learning algorithm that can analyse skin cancer as accurately as a human doctor. Now, Israel-based company, Medical EarlySign has announced the ability of its AI tool to identify the top 1% at highest risk of undiagnosed colorectal cancer (CRC). The machine learning developer announced the first-year results of its implementation with Maccabi Healthcare Services (MHS), for ColonFlag, a tool developed in collaboration with MHS to identify individuals with a high probability of having CRC.

If a tree falls in Peru's rainforest, Greg Asner can tell you what kind it was. Asner, an ecologist at the Carnegie Institution for Science and Stanford University, uses artificial intelligence and a powerful spectral imaging method to map the rainforest in unprecedented detail. By identifying each tree species by its chemical composition, he has shown the rainforest is more diverse than anyone thought. Asner's map takes the guesswork out of protecting one of the most biodiverse places on Earth and pinpointing new areas for conservation. "It's really advancing our ability to save forests and curb climate change," he said.

We can roughly divide the year into two halves: September through February is the "Release" bit, and March through August the "Hype" bit. Sure, there are exceptions--games get released all year long at this point. The Game Developer's Conference, which took place this week in San Francisco and where we start to see news about the year's most-anticipated games. Another solid Humble Bundle this week, this time focused on the Arma series. The tiers are a bit complicated but basically $1 gets you the original Arma, beating the average gets you Arma 2, and paying $15 or more gets you Arma 3. If you're looking for a hellishly complicated but ultra-rewarding military sim, Arma's a damn good choice--or if you just want to play the original DayZ, before it fell into Early Access hell.

Bolivia may be one of the cocaine capitals of the world – but don't you dare call it a narco state. The Bolivian government complained to France after a French video game publisher, Ubisoft, developed a game that highly offended the South American nation. The popular game, "Tom Clancy's Ghost Recon Wildlands," revolves around a Mexican drug cartel that controls Bolivia and has turned the country into a violent narco-state. The game is set to be officially launched next week, but the game's beta version has already been downloaded by 6.8 million users. Bolivian Interior Minister Carlos Romero said the Andean nation delivered a letter to the French ambassador earlier this week and asked French officials to intervene.

Ghost Recon: Wildlands comes out next week. I know, I almost forgot about it too. But if an open world filled with guns, high-speed chases and sniping over huge distances in Bolivia is more your speed than robotic dinosaurs or some random game with a princess, you might be interested to know what Wildlands has in store after launch. You know, for when you've long since finished its campaign and dominated the competition on the packed-in multiplayer maps. First up: there's a season pass because this is a modern video game being released by a major publisher.
