When Kevin Oldt crashed his snowmobile in January 2001, his doctors told him that his spinal cord injury meant he'd never walk again. So it's with great satisfaction that he tells me his personal record for walking with the help of a robotic exoskeleton from Ekso Bionics: about 5000 steps in one day. He clocked those steps in a Dallas convention hall where he spent four hours on the show floor demonstrating the features of the Ekso GT, the company's current commercial model. "And I didn't feel tired," he says. Oldt recently gave IEEE Spectrum a personal demo at a New York City hotel [video below], accompanied by Ekso CEO Tom Looby and an Ekso physical therapist.

It was the best of times p His photographs capture the culture of rock and punk music; the beguiling moments with the Ramones, Patti Smith, Talking Heads, Blondie, Dead Boys, Richard Hell, Lydia Lunch and many more as they made New York's CBGB club their home in the late 1970s. John Thackwray, a French and South African commercial filmmaker and photographer, has traveled the globe since 2010, and photographed over 1,200 bedrooms of young people born in the 1980s and 1990s. More than a decade ago, the European Space Agency launched an orbiter named Rosetta, bound on a circuitous voyage to comet 67P/Churyumov-Gerasimenko. In the years since, Rosetta has been drawn in and flung along by multiple gravity assist maneuvers, visiting the Earth three times and making … A few weeks ago we suggested you follow 5 topics that cover the more basic aspects of the business of blogging.

The United States is planning to invest in a military air base in the Northwest African country of Niger. The base will have the capacity of deploying drones and the investment reportedly stands at at least 50 million. The development of the new military base is expected to see the transfer of U.S. assets in the region from the U.S.'s shared air base with France's anti-Islamist force -- Operation Barkhane -- in Niger's capital city of Niamey to the new facility in the city of Agadez. This includes the MQ-9 Reaper drones. The new base, which will provide the U.S. greater access to Islamist extremists in neighboring countries like Libya, Mali and Nigeria, will cost the country an estimated 50 million, BBC quoted Michelle Baldanza, a spokeswoman for the Pentagon, as saying.

Earlier this week, a Tesla car crashed into a tourist bus on a motorway in northern Germany with the driver claiming he had activated the car's autopilot system. But the firm says that autopilot was not to blame for the crash. Instead, it says that the collision was unavoidable because the bus swerved into the vehicle's lane. Earlier this week, a Tesla car crashed into a tourist bus on a motorway in northern Germany with the driver claiming he had activated the car's autopilot system (stock image) The US Department of Transportation may propose requiring all new cars to have vehicle-to-vehicle communication, known as V2V, as early as this autumn. The federal government estimates that V2V connectivity could ultimately prevent or reduce the severity of about 80 percent of collisions that don't involve a driver impaired by drugs or alcohol.

In the early 1990s, Iris Murdoch was writing a new novel, as she'd done 25 times before in her life. But this time something was terribly off. Her protagonist, Jackson, an English manservant who has a mysterious effect on a circle of friends, once meticulously realized in her head, had become a stranger to her. As Murdoch later told Joanna Coles, a Guardian journalist who visited her in her house in North Oxford in 1996, a year after the publication of the book, Jackson's Dilemma, she was suffering from a bad writer's block. It began with Jackson and now the shadows had suffused her life. "At the moment I'm just falling, falling … just falling as it were," Murdoch told Coles.

I doubt that any phenomenon, real or imagined, has inspired more perplexing, convoluted, and ultimately futile philosophical analysis than time travel has. In his classic textbook, An Introduction to Philosophical Analysis, John Hospers tackles the question: "Is it logically possible to go back in time--say, to 3000 B.C., and help the Egyptians build the pyramids? We must be very careful about this one." It's easy to say--we habitually use the same words to talk about time as we do when talking about space--and it's easy to imagine. "In fact, H. G. Wells did imagine it in The Time Machine (1895), and every reader imagines it with him." Hospers was a bit of a kook, actually, who achieved the unusual distinction for a philosopher of having received one electoral vote for President of the United States. But his textbook, first published in 1953, remained standard through four editions and 40 years. His answer to the rhetorical question is an emphatic no. Time travel à la Wells is not just impossible, it is logically impossible. It is a contradiction in terms. In an argument that runs for four dense pages, Hospers proves this by power of reason. "How can we be in the 20th century A.D. and the 30th century B.C. at the same time? Here already is one contradiction … It is not logically possible to be in one century of time and in another century of time at the same time."

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
