Dawit Haile fought against the odds when he decided to study computer science in Eritrea, East Africa, despite having no internet connectivity. His perseverance paid off, first landing a job with the Eritrean government department of education, and later as an engineer in Lithuania. Today, Dawit is a data scientist in the San Francisco Bay Area, and he credits this new job to the knowledge and experience he gained from fast.ai. On the side, he's building an algorithm to translate between English and his native language of Tigrinya. Dawit is just one of many impressive fast.ai

One of the biggest mysteries among people working on salmon recovery in Puget Sound and the Salish Sea is what happens to juvenile fish once they head for the ocean. Survival rates of Chinook, Coho and Steelhead have all declined since the 1980s, but resource managers don't know why. A new grant from Microsoft is using artificial intelligence to greatly improve the computer models used to tackle the question. A collaborative effort called the Salish Sea Marine Survival Project has been around for nearly a decade. It unites the work of 60 different scientific and non-profit entities, all trying to understand what is preventing salmon and steelhead from coming home.

Two years after World War II, billionaire Howard Hughes personally piloted his "Spruce Goose" troop transport aircraft on the first and only flight of the largest seaplane ever built. It lasted barely a minute. Now, more than 70 years later, a U.S. startup is testing a new seaplane concept--one that could evolve into huge cargo drones that fly 109 metric tons of freight across the Pacific, touch down autonomously over water, and unload at ports around the world. The startup Natilus was founded in 2014 with a dream of building large cargo drones to deliver international freight for about half the price of piloted aircraft, and much faster than ships. In December, Natilus planned to test the water-taxiing capabilities of a small prototype drone with a 9-meter wingspan in San Francisco Bay.

Tensions between poachers and conservationists in the Gulf of California escalated over the weekend after a fisherman shot down a drone being used to monitor illegal activities. The drone belonged to the U.S. conservation group Sea Shepherd, which has two ships in the northern part of the Sea of Cortez as part of an effort to save the critically endangered vaquita porpoise. The vaquita have been inadvertently caught in nets that poachers use to catch the endangered totoaba fish. Fishermen can make huge sums on the black market for dried totoaba swim bladders, which are sold in China for their supposed medicinal properties. The environmental group has been searching for nets and pulling them from the water.

Game developers were researching AI well before it became a tech industry trend, but they haven't had much incentive to share their work with the academic world. Ubisoft, however, is trying to find a happy middle ground. It recently established an AI research wing, La Forge, that aims to harmonize research for both gaming and science. The new unit has academics and Ubisoft employees working together on projects that will ideally advance gaming and lead to real-world breakthroughs that scientists can publish. As an example, Ubisoft points to its work on creating a small-scale version of the San Francisco Bay Area for Watch Dogs 2. The company developed AI-guided cars and pedestrians to navigate a realistic urban environment, and that's potentially ideal for self-driving car research -- scientists could use Watch Dogs' technology to test autonomous driving in tricky situations (such as crowds) without having to put real cars on the road.

Stunning concept images for the world's first first floating nation have been released as part of a project bankrolled by PayPal founder Peter Thiel. The plans will see the seabound city-state, complete with a handful of hotels, homes, offices, restaurants and more, built in the Pacific Ocean off the island of Tahiti in 2020. Now, a series of computer generated graphics reveal how it might look once complete, with a design that blends futuristic technology with Polynesian traditions. Stunning concept images for the world's first first floating nation have been released as part of a project bankrolled by PayPal founder Peter Thiel. Floating islands would feature aquaculture farms, healthcare, medical research facilities, and sustainable energy powerhouses.

LiDAR is having a moment right now helping self-driving cars and robots not hit things, but don't forget about what else it can do. In a study called The Bare Earth, scientists from the Washington Geological Survey used it to image the ground right down to dirt and rocks. Stripped of trees and other distractions, the images provide not only valuable geological survey data, but stunning, otherworldly views of our planet. The image above depicts a LiDAR relative elevation model (REM), showing current and previous channels carved out by the Sauk River in Washington State's Skagit and Snohomish counties. In the regular satellite image below, however, only the active, vegetation-free channels are clearly visible -- a striking display of what the technique can reveal.

Using conditional instance normalisation a single style transfer network can capture 32 style simultaneously, five of which are displayed here. This work will feature in the International Conference on Learning Representations (ICLR) 2017. Source: Dumoulin et al. (2017, p. 2)[79] Style transfer as a topic is fairly intuitive once visualised; take an image and imagine it with the stylistic features of a different image. This year Facebook released Caffe2Go,[80] their deep learning system which integrates into mobile devices.

The world's first floating nation is set to appear in the Pacific Ocean off the island of Tahiti in 2020. A handful of hotels, homes, offices, restaurants and more will be built in the next few years by the nonprofit Seasteading Institute, which hopes to'liberate humanity from politicians'. The radical plans, bankrolled by PayPal founder Peter Thiel, could see the creation of an independent nation that will float in international waters and operate within its own laws. In a new interview, Joe Quirk, president of the Seasteading Institute, said he wants to see'thousands' of rogue floating cities by 2050, each of them'offering different ways of governance'.

Deep sea explorers sent a drone to the ocean floor to beam back stunning images of the USS Indianapolis, a naval gunship that lies three miles beneath the surface of the Philippine Sea 72 years ago, in a dramatic live broadcast on Wednesday. Findings from the footage enabled experts to piece together the final moments of the WWII ship, which was discovered by Microsoft co-founder Paul Allen last month. The ship was sunk by a Japanese torpedo in the final days of World War Two, more than 18,000 feet below the surface of the Pacific Ocean, the Navy said. From the new drone footage, researchers have concluded that two Japanese torpedoes hit the ship, one of them striking an area near a chamber with crew members that likely would have died immediately upon impact. Researchers also discovered guns, torpedo remnants and parts of aircraft that were preserved thanks to the extremely cold temperatures at the bottom of the sea.
