Two multi-million pound British Army drones crashed after taking off from a base in mid Wales, the Ministry of Defence has confirmed. The unmanned Watchkeeper aircraft were lost in the Irish Sea earlier this year, leading commanders to temporarily ground the entire fleet. Flight trials resumed at Aberporth Airport in Ceredigion in early July. The crashes are the latest in a series of accidents and delays to have hit the Army's new spy planes. The MoD ordered 54 Watchkeepers in 2005 as part of an £847m deal.

There is no denying the fact that Artificial Intelligence is the breakthrough technology of recent times. The machines have come a long way from assisting humans in mechanical operations to performing smarter tasks using cognitive intelligence. Every day, we are coming across interesting applications of AI. The ability of Deep Learning algorithms to learn and predict efficiently has opened the doors of possibilities. Nowadays, AI is impacting many other areas as well.

When the crew of an $80-million super-yacht in the Ionian Sea checked its computer, they realized they were drifting slightly off course, likely as a result of strong currents buffeting their ship. The crew made adjustments and went back to work--without realizing they were now taking directions from a hacker. In the bowels of the ship, Todd Humphreys, an associate professor in the Department of Aerospace Engineering and Engineering Mechanics at the University of Texas at Austin, worked with his team to feed the super-yacht's crew false navigation data using a few thousand dollars worth of hardware and software. The crew was completely unaware they were now piloting in a direction of Humphreys' choosing. Thankfully, it was all an experiment that took place with the yacht owner's blessing.

Participants run ahead of Puerto de San Lorenzo's fighting bulls during the third bull run of the San Fermin festival in Pamplona, northern Spain. Each day at 8:00 am hundreds of people race with six bulls, charging along a winding, 848.6-metre (more than half a mile) course through narrow streets to the city's bull ring, where the animals are killed in a bullfight or corrida, during this festival, immortalised in Ernest Hemingway's 1926 novel "The Sun Also Rises" and dating back to medieval times and also featuring religious processions, folk dancing, concerts and round-the-clock drinking. Iraqi women, who fled the fighting between government forces and Islamic State (IS) group jihadists in the Old City of Mosul, cry as they stand in the city's western industrial district awaiting to be relocated

After roaming the planet for 165 million years, it is thought the dinosaurs were wiped off the face of the planet when an asteroid crashed into Earth 66 million years ago. The impact of the asteroid would have thrown up huge amounts of debris, and new computer simulations have revealed the extent to which this affected our planet. The findings suggest that Earth would have been plunged into darkness for as long as two years. The impact of the asteroid would have thrown up huge amounts of debris, and new computer simulations have revealed the extent to which this affected our planet (artist's impression) The team used computers to model what Earth might have looked at the end of the Cretaceous Period, after a large asteroid struck what is now the Yucatán Peninsula, beneath the gulf of Mexico. The simulations found 15,000 million tons of soot would have been sent into the atmosphere after the asteroid hit, forming a barrier between the Earth and sunlight.

Costing £3.1billion and weighing 65,000 tonnes, she's Britain's biggest and most advanced warship ever built. But HMS Queen Elizabeth has been outmanoevred by a £300 drone which landed on the deck completely unchallenged. The drone pilot, who wanted to remain anonymous, made the daring flight while the aircraft carrier was docked at Invergordon, Scotland in July. He flew over the carrier before touching down on the four-acre deck and then taking off again unchecked. Princess Diana's driver: Her death'stirred things within me' The flight may now be discussed in Scotland's Parliament by MSPs concerned about security flaws.

Reports of satellite navigation problems in the Black Sea suggest that Russia may be testing a new system for spoofing GPS, New Scientist has learned. This could be the first hint of a new form of electronic warfare available to everyone from rogue nation states to petty criminals. On 22 June, the US Maritime Administration filed a seemingly bland incident report. The master of a ship off the Russian port of Novorossiysk had discovered his GPS put him in the wrong spot – more than 32 kilometres inland, at Gelendzhik Airport. After checking the navigation equipment was working properly, the captain contacted other nearby ships. Their AIS traces – signals from the automatic identification system used to track vessels – placed them all at the same airport.

Satellites in space and a robot under Lake Erie's surface are part of a network of scientific tools trying to keep algae toxins out of drinking water supplies in the shallowest of the Great Lakes. It's one of the most wide-ranging freshwater monitoring systems in the U.S., researchers say, and some of its pieces soon will be watching for harmful algae on hundreds of lakes nationwide. Researchers are creating an early warning system using real-time data from satellites that in recent years have tracked algae bloom hotpots such as Florida's Lake Okeechobee and the East Coast's Chesapeake Bay. Satellites in space and a robot under Lake Erie's surface are part of a network of scientific tools trying to keep algae toxins out of drinking water supplies in the Great Lakes. The system in development will cast a wider net at a time when many states can't afford to monitor every lake threatened by harmful algae.

TOLEDO, OHIO – Satellites in space and a robot under Lake Erie's surface are part of a network of scientific tools trying to keep algae toxins out of drinking water supplies in the shallowest of the Great Lakes. It's one of the most wide-ranging freshwater monitoring systems in the U.S., researchers say, and some of its pieces soon will be watching for harmful algae on hundreds of lakes nationwide. Researchers are creating an early warning system using real-time data from satellites that in recent years have tracked algae bloom hotpots such as Florida's Lake Okeechobee and the East Coast's Chesapeake Bay. The plan is to have it in place within two years so that states in the continental U.S. can be alerted to where toxic algae is appearing before they might detect it on the surface, said Blake Schaeffer, a researcher with U.S. Environmental Protection Agency. "You don't have to wait until someone gets sick," said Schaeffer, one of the leaders of the project.

Humans are formed from matter that flew billions of miles from another galaxy, according to a new study. Much of the stuff around us and spread throughout our Milky Way is made up of "extragalactic matter", according to the research. The study used computer models to find out how the matter around us came to be acquired by our galaxy. It found that supernova explosions throw out huge amounts of matter from galaxies, spreading it throughout the universe as it is carried on powerful galactic winds. 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.
