In a feat reminiscent of the controversial victory by supercomputer'Deep Blue' over world chess champion Garry Kasparov, a computer program has managed to beat a string of professional poker players at the game. DeepStack, as it was called, defeated 10 out of 11 players who took part in a total of 3,000 games as part of a scientific study into artificial intelligence. The 11th player also lost, but by a margin that the researchers decided was not large enough to be statistically significant. This is not the first time a computer has won at poker. Libratus, a program developed by Carnegie Mellon University academics, won $1.76m (£1.4m) from professionals in January, for example.

An important shipment has finally arrived at the International Space Station, after a series of errors, delays and challenges. The SpaceX capsule smoothly arrived at the station the second time around as astronauts grabbed hold of the cargo ship, as the two of them floated somewhere over Australia. The capsule had been scheduled to arrive on Wednesday. But a GPS error stopped it from getting too close and the move had to be aborted. 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.

Nasa might have announced the biggest exoplanet find ever, but gamers are already gearing up find the next one. As scientists announced that they had found the "holy grail" of exoplanets – a solar system of seven worlds that could support life – a game announced that it was beginning the search for the next one. Massively multiplayer online game EVE Online has announced that it will be launching a search for planets orbiting our solar system, looking through the huge amount of data and images captured of other planets in our galaxy.

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.

Nasa might soon launch our best ever chance of meeting aliens. The space agency is putting together plans to send a lander to Europa, one of Jupiter's moons and perhaps the most likely place to harbour alien life anywhere near us. But first they will have to work out how they can actually land on a surface about which they know next to nothing. The agency started seriously exploring that possibility by commissioning a report on the value of sending a lander onto the icy surface of the moon. That report has now arrived and Nasa is looking to explore its findings with the scientific community.

The British Navy has fired its first torpedo using a radical new'brain' fitted to a nuclear submarine. The Royal Navy's latest and most advanced Astute class submarine, Artful, used the Common Combat System for the first time. It is the first to use this new technology which is now being retrofitted to earlier Astute class submarines. The new system, provided by VMware, Dell and Aish, processes information from submarine sensors to enable crew members to make important command decisions. It was used during the test to interpret sonar readings and then attack a moving target with a practice weapon.

They are the ultimate symbol of military might, capable of providing a dominant presence in almost any region of the world where there is a nearby ocean. But as technology has advanced, the hulking weaponry and armour of warships that have ruled the waves are having to change and adapt to these high-tech times. From drones to unmanned boats and laser weapons, experts at How It Works Magazine have revealed what fleets of the future will look like. From drones to unmanned boats and laser weapons, experts at How It Works Magazine have revealed what fleets of the future will look like. This artist's impression shows a selection of some of the features that could make their way onto warships over the next decade The Royal Navy in the UK has been challenging young British scientists and engineers to design the fleet of the future.

One day, gardeners might not just hear the buzz of bees among their flowers, but the whirr of robots, too. Scientists in Japan say they've managed to turn an unassuming drone into a remote-controlled pollinator by attaching horsehairs coated with a special, sticky gel to its underbelly. The system, described in the journal Chem, is nowhere near ready to be sent to agricultural fields, but it could help pave the way to developing automated pollination techniques at a time when bee colonies are suffering precipitous declines. In flowering plants, sex often involves a threesome. Flowers looking to get the pollen from their male parts into another bloom's female parts need an envoy to carry it from one to the other.

Given an agricultural watershed containing a set of spatial units, and a set of land management practices, the Geodesign Optimization (GOP) aims to find a land management practice for each spatial unit that optimizes overall water quality improvements in the watershed under both budget constraint and spatial constraints (e.g., minimum contiguous area, shape) arising from farm equipment operation practicalities. GOP is important for redesign of agricultural watersheds in Midwestern US to mitigate soil and water quality degradation and loss of habitat. The problem is computationally challenging as a large-scale combinatorial problem (NP-hard) under spatial constraints. Existing optimization techniques do not address spatial constraints, and lead to impractical solutions requiring frequent farm equipment reconfiguration. In this paper, we formalize the spatially-constrained GOP and propose a novel spatial optimizer which explores optimal solution without constraint violations. Our approach is further validated through a Geodesign case study at Seven Mile Creek watershed in Midwestern US.

Donald Trump has promised to "unlock the mysteries of space" in his time as President. The commitment came as one of a range of vague commitments made as part of his inauguration speech. Following a long passage in which he berated politicians for talking too much, President Trump said that "The time for empty talk is over". "Now arrives the hour of action," he said.

In December, Amazon announced that it intended to deliver packages to customers using drones. But its "Amazon Prime Air" initiative, revealed on US current affairs show 60 Minutes, was widely ridiculed for being an over-hyped announcement with little to show for it. This summer, Google demonstrated its own drone-based delivery service, using a fixed-wing aircraft to deliver packages including chocolate bars, dog treats and cattle vaccines to farmers in the Australian outback. But now, German delivery firm DHL has beaten the tech firms to the post, announcing a regular drone delivery service for the first time, nine months after it launched its "parcelcopter" research project in December 2013. The service will use an autonomous quadcopter to deliver small parcels to the German island of Juist, a sandbar island 12km into the North Sea from the German coast, inhabited by 2,000 people.
