A pioneering artificial intelligence has been used to spot dozens of mysterious signals coming from deep in space. The new AI spotted 72 previously undiscovered "fast radio bursts" emanating out of distant galaxies, according to Breakthrough Listen, a program searching for proof of life elsewhere in the universe. FRBs have long been thought to be one of the mysterious phenomena in the universe. They are intense blasts of radio emissions that can be detected on Earth and then switch off. From the International Space Station, Expedition 42 Flight Engineer Terry W. Virts took this photograph of the Gulf of Mexico and U.S. Gulf Coast at sunset This image of an area on the surface of Mars, approximately 1.5 by 3 kilometers in size, shows frosted gullies on a south-facing slope within a crater. The image was taken by Nasa's HiRISE camera, which is mounted on its Mars Reconaissance Orbiter The Soyuz TMA-15M rocket launches from the Baikonur Cosmodrome in Kazakhstan on Monday, Nov. 24, 2014, carrying three new astronauts to the International Space Station.

The Japanese space agency will land two robots on an asteroid next month – the latest step in historic plans to explore its surface and bring samples back to Earth. The mission to the 1km-wide space rock, known as Ryugu, could provide clues not only to the asteroid's formation but to the formation of our solar system. The Japanese space agency have now selected dates for the deployment of smaller crafts from Hayabusa-2 . From the International Space Station, Expedition 42 Flight Engineer Terry W.

Scientists have developed a spear-wielding submersible robot to hunt invasive lionfish in the western Atlantic Ocean. The fish have become a major problem in the waters off the coastal US and Caribbean islands; originally from the South Pacific and Indian oceans, lionfish have no natural predators in the area and are now out-competing native species. Researchers are now hoping an autonomous robot can help solve the problem by weeding out the lionfish and harvesting them without causing further damage to struggling coral reefs. Scientists have developed a spear-wielding submersible robot to hunt invasive lionfish in the western Atlantic Ocean. 'There are economic and environmental benefits to this, and the fish are delicious,' says Brandon Kelly, an undergraduate student at Worcester Polytechnic Institute who developed the robot's computer vision system.

Since he was a child, Derek Paley has been captivated by how shoals of fish move fluidly as a cohesive group, almost as if a single organism. As the Willis H. Young Jr. Professor of Aerospace Engineering Education and director of the Collective Dynamics and Control Laboratory at the University of Maryland, Paley is applying his long-standing source of inspiration to the cooperative control of autonomous vehicles. Fish are particularly interesting for Paley because of their sensory system. He explains that fish have a lateral line system, which is a series of sensors located on their exterior, sometimes appearing on their side as a stripe. With their lateral line sense, fish can perceive the direction and speed of nearby water flow, as well as predators and other obstacles.

Common-sense and background knowledge is required to understand natural language, but in most neural natural language understanding (NLU) systems, this knowledge must be acquired from training corpora during learning, and then it is static at test time. We introduce a new architecture for the dynamic integration of explicit background knowledge in NLU models. A general-purpose reading module reads background knowledge in the form of free-text statements (together with task-specific text inputs) and yields refined word representations to a task-specific NLU architecture that reprocesses the task inputs with these representations. Experiments on document question answering (DQA) and recognizing textual entailment (RTE) demonstrate the effectiveness and flexibility of the approach. Analysis shows that our model learns to exploit knowledge in a semantically appropriate way.

Humans gather information by engaging in conversations involving a series of interconnected questions and answers. For machines to assist in information gathering, it is therefore essential to enable them to answer conversational questions. We introduce CoQA, a novel dataset for building Conversational Question Answering systems. Our dataset contains 127k questions with answers, obtained from 8k conversations about text passages from seven diverse domains. The questions are conversational, and the answers are free-form text with their corresponding evidence highlighted in the passage. We analyze CoQA in depth and show that conversational questions have challenging phenomena not present in existing reading comprehension datasets, e.g., coreference and pragmatic reasoning. We evaluate strong conversational and reading comprehension models on CoQA. The best system obtains an F1 score of 65.1%, which is 23.7 points behind human performance (88.8%), indicating there is ample room for improvement. We launch CoQA as a challenge to the community at http://stanfordnlp.github.io/coqa/

Alphabet is broken out into its core Google business and a number of other subsidiaries, which it deems "Other Bets." The majority of Google's business comes from advertising revenues, which the company generates through its search engine as well as a number of other Google-affiliated and partnership websites. Outside of search and advertising, Google generates revenue from products including cloud and enterprise, consumer hardware, mapping, and YouTube. In addition to Google, Alphabet encompasses a host of other subsidiaries called "Other Bets." These companies are more experimental in nature, and as a result are not material to Alphabet's bottom line.

As artificial intelligence (AI) makes a "powerful impact" on other sectors, more North Sea players are expected to deploy digital innovations. Louise Sayers is head of natural resources at advisory firm BDO, whose comments come as Shell announced its commitment to the North Sea yesterday. The energy giant said it hopes to be in the region for another 50 years, as it celebrates five decades of North Sea production. Ms Sayers said this was welcome news, and said now is the time for the North Sea to "grasp digital innovation". She said: "Oil and gas companies were forced to ruthlessly cut costs and sharpen their investment filters to survive the oil price crash in 2014.

Canada's rankings in innovation has lagged that of other peer nations for decades despite government efforts to address this issue. Considering its success in developing research programs at its universities, its mediocre rankings overall in technology development is disappointing. Those programs alone have not been enough to translate into entrepreneurial innovation. A 2017 C.D. Howe Institute study points out that, even though Canadians have been at the forefront of breakthroughs in emerging technologies, in many cases, the chief beneficiaries of those breakthroughs have been other nations' economies. Canada needs to take a stronger role in building an environment in which Canadian know-how spurs Canadian business growth. According to a 2017 PwC global survey, Canadian companies stand significantly ahead of their global counterparts in having a dedicated team for digital innovation, with 54% of Canadian respondents reporting that their company does, as opposed to 43% of global respondents. Looking deeper, though, shows a far less innovative spirit, as 47% of respondents said that their pursuit of digital innovation takes the form of seeking to copy others' innovations rather than pursuing their own. Already a decade ago, experts recognized factors that constrain Canadian innovation growth. A 2009 study by the Council of Canadian Academies pointed to two key issues that have held Canadian businesses back from prioritizing innovation in their business strategies. The first issue deals with what has been called "the resource curse." Canada is largely "upstream" in the international supply chain, providing raw materials for other businesses that create products that are in turn passed down the value chain until they reach the stage of finished products sold to end customers. That places Canada in a position far distant from end customers, whose evolving needs spur businesses at the downstream end of the supply chain to adapt, which, in turn, spurs innovation.

As Britain braces for a second bout of scorching weather this weekend, experts have warned this summer could finally break the records set by the infamous heatwave of 1976. The blistering temperatures in June stood toe-to-toe with those of June 1976, while this summer's July was hotter than its counterpart 42 years ago. If Britain is hit by a hotter-than-average August - as has been forecast by advanced computer models - 2018 could be the hottest summer ever recorded. This year's prolonged heat is the result of a number of factors, including extended high pressure and higher than average surface temperatures in the Atlantic Ocean. Experts have also warned that rising global temperatures caused by climate change are making the heatwaves gripping the northern hemisphere more ferocious and more likely.
