If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."
However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) …
Shell has doubled its spending on clean power and bowed to shareholder pressure by promising to halve the carbon footprint of the energy it sells by 2050, as the oil giant said it was stepping up its ambitions on green energy. The Anglo Dutch firm is increasing capital expenditure for its new energies division, to $1bn-$2bn (£750m to £1.5bn) a year for 2018-2020, up from a previous plan of up to $1bn a year by 2020. But the spending on wind power, biofuels and electric car infrastructure will still account for a small fraction of the giant's planned $25-30bn annual investment. Shell has $5bn-$6bn a year pegged for deepwater drilling and $2-3bn a year allocated for shale oil and gas. The company's new climate change target aims to cut the net carbon footprint of its products in half by 2050, and around one-fifth by 2035.
Images captured by an underwater robot on Saturday showed massive deposits believed to be melted nuclear fuel covering the floor of a damaged reactor at Japan's destroyed Fukushima nuclear plant. The robot found large amounts of solidified lava-like rocks and lumps in layers as thick as 1m on the bottom inside a main structure called the pedestal that sits underneath the core inside the primary containment vessel of Fukushima's Unit 3 reactor, said the plant's operator, Tokyo Electric Power Co. On Friday, the robot spotted suspected debris of melted fuel for the first time since the 2011 earthquake and tsunami caused multiple meltdowns and destroyed the plant. Locating and analysing the fuel debris and damage in each of the plant's three wrecked reactors is crucial for decommissioning the plant. During this week's probe, cameras mounted on the robot showed extensive damage caused by the core meltdown, with fuel debris mixed with broken reactor parts, suggesting the difficult challenges ahead in the decades-long decommissioning of the plant.
The legislation empowers the National Oceanic Atmospheric Administration (NOAA) to boost its ability to predict major weather-related events, such as hurricanes, droughts, floods and wildfires. Using faster, more powerful computers and more detailed data of weather patterns could increase the accuracy, Seitter says. Businesses have been able to access accurate, customizable weather forecasting online only in the last decade or so, says Bill Gail, chief technology officer at private forecaster Global Weather Corporation. Xcel Energy, who uses Gail's firm to anticipate wind energy production, improved its wind forecasting accuracy by nearly 35% from 2009 to 2015.
