DEVELOPING: A contractor who threatened to set off a bomb at the headquarters of Fox 45 Baltimore Thursday afternoon, forcing police to evacuate the building, walked outside before a sniper shot him as cameras rolled. The suspect, a man in his 20s, was still alive but refused to cooperate with officers, police spokesman T.J. Smith said. Reporters said they saw him kick off some of his clothing. When he walked out of the building, he was wearing a white panda suit, a surgical mask and sunglasses. Robot trying to get suspect to show his hands.

The phrase "reasonable expectation of privacy" is linked to the Fourth Amendment in the same way the phrase "I'll be back" is linked to the Terminator franchise. In essence, it dictates the applicability of the law guaranteeing "the right of the people to be secure in their persons, houses, papers, and effects." Given that the Supreme Court has always treated American homes as more or less sacrosanct, it seems likely that there's nothing to fear from the government (unless you give law enforcement probable cause). For civilians, privacy laws have traditionally done a pretty good job of protecting Americans from invasive or inappropriate photography or recordings. That does not mean, however, that recordings don't go public.

Man-machine collaboration could reach new heights far from home, as humanoid robots show potential for deep-space travel. NASA has sent prototype robots to two university groups for further research and development. Initially designed for disaster relief during a previous robotics challenge, the R5 robots could someday be among the first to demonstrate humanoid robot models' usefulness for distant space missions, the space agency suggests. "Advances in robotics, including human-robotic collaboration, are critical to developing the capabilities required for our journey to Mars," Steve Jurczyk, associate administrator for the Space Technology Mission Directorate (STMD) at NASA Headquarters, said in a press release. "We are excited to engage these university research groups to help NASA with this next big step in robotics technology development."

In the 2004 film I, Robot, Will Smith's character Detective Spooner harbors a deep grudge for all things technological -- and turns out to be justified after a new generation of robots engage in a full out, summer blockbuster-style revolt against their human creators. Why was Detective Spooner such a Luddite–even before the Robots' vicious revolt? Much of his resentment stems from a car accident he endured in which a robot saved his life instead of a little girl's. The robot's decision haunts Smith's character throughout the movie; he feels the decision lacked emotion, and what one might call'humanity'. "I was the logical choice," he says. "(The robot) calculated that I had a 45% chance of survival. Sarah only had an 11% chance." He continues, dramatically, "But that was somebody's baby. A human being would've known that."

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display

SpaceX founder Elon Musk plans to send a capsule to Mars in 2018. The company is going to send one of its Dragon capsules - in this case known as the Red Dragon - to the planet. It won't carry any astronauts with it, but represents Mr Musk's first step towards his ultimate plan of colonising Mars. For now, the Dragon is too small to carry astronauts further than the Moon, he said, since it is about the size of a large family car. "Wouldn't be fun for longer journeys," Mr Musk explained in a tweet.

The Ying Ao sink foundry in southern China's Guangdong province does not look like a factory of the future. The sign over the entrance is faded; inside, the floor is greasy with patches of mud, and a thick metal dust -- the by-product of the stainless-steel polishing process -- clogs the air. Guangdong is the growth engine of China's manufacturing industry, generating 615bn in exports last year -- more than a quarter of the country's total. In this part of the province, the standard wage for workers is about Rmb4,000 ( 600) per month. Ying Ao, which manufactures sinks destined for the kitchens of Europe and the US, has to pay double that, according to deputy manager Chen Conghan, because conditions in the factory are so unpleasant. So, four years ago, the company started buying machines to replace the ever more costly humans. Nine robots now do the job of 140 full-time workers.

New supersharp photos of Mars show Europe's long-lost Beagle 2 lander, ancient Red Planet lake beds and snaking rover tracks in unprecedented detail. Scientists "stacked and matched" photos captured over the years by NASA's eagle-eyed Mars Reconnaissance Orbiter (MRO) using new machine-vision methods, creating images in which features just 2 inches wide can be seen. This resolution is five times greater than MRO or any other instrument orbiting Earth or Mars had been able to achieve, researchers said. Further use of this technique could help space agencies select safe landing sites for future Mars missions, search for pieces of other lost Red Planet hardware and perform a variety of other science work, they added. "We now have the equivalent of drone-eye vision anywhere on the surface of Mars where there are enough clear repeat pictures," study co-author Jan-Peter Muller, of University College London's Mullard Space Science Laboratory, said in a statement.

A couple have been told to restrain their cat or face having their mail deliveries suspended. Matthew Sampson was notified by Royal Mail last week of a "potential hazard" at his home in South Gloucestershire which was "affecting deliveries". According to Royal Mail, Bella the cat is a "threat" to staff and has been putting "fingers at risk of injury". But owner Matthew Sampson, said he was "shocked" by the notice as he has "never seen her get aggressive". In the letter, Royal Mail states it has been "experiencing difficulties in delivering mail" to Mr Sampson's address in Patchway "because of the actions of a cat". It said the couple's postman had reported that when he pushes mail through their letterbox their cat "snatches the mail and put his fingers at risk of injury".
