For example, they created a prototype of an improved telescope mirror mount. The part at the top near the glass mirror is made of a metal with low thermal expansion, so that it won’t shrink in space as much as most metals do. That prevents stress in the epoxy adhesive between the mirror and the metal. The bottom part of this mount is stronger stainless steel and could be connected to a stainless steel component of a spacecraft.
A new Terminator T-1000 robot-style material made of wax and foam — and capable of switching between hard and soft states — could be used to build morphing surgical robots that move through the body to reach a desired location without damaging organs or vessels along the way.
Robots built from the material, described in a new paper in the journal Macromolecular Materials and Engineering, could also be used in search-and-rescue operations to squeeze through rubble looking for survivors, says Anette Hosoi, an MIT professor of mechanical engineering and applied mathematics who led the research team.
In a quiet announcement that has sent shockwaves through the scientific world, Nasa has cautiously given its seal of approval to a new type of “impossible” engine that could revolutionize space travel.
In a paper published by the agency’s experimental Eagleworks Laboratories, Nasa engineers confirmed that they had produced tiny amounts of thrust from an engine without propellant – an apparent violation of the conservation of momentum; the law of physics that states that every action must have an equal and opposite reaction.
Communications regulator Ofcom said UK adults spend an average of eight hours and 41 minutes a day on media devices, compared with the average night’s sleep of eight hours and 21 minutes.
Almost four hours a day are spent watching TV according to Ofcom’s survey of 2,800 UK adults and children.

As late as the 1980s and the 1990s, the common person seeking stored knowledge would likely be faced with using an 18th century technology — the library index card catalogue — in order to find something on the topic he or she was looking for. Fifteen years later, most people would be able to search, at any time and any place, a collection of information that dwarfed that of any library. And unlike the experience with a library card catalogue, this new technology rarely left the user empty-handed.
Information retrieval had been a core technology of humanity since written language — but as an actual area of research it was so niche that before the 1950s, nobody had bothered to give the field a name. From a superficial perspective, the pioneering work in the area during the 1940s and 50s seemed to suggest it would be monumentally important to the future — but only behind the scenes. Information retrieval was to be the secret tool of the nation at war, or of the elite scientist compiling massive amounts of data. Increasingly however, a visionary group of thinkers dreamed of combining information retrieval and the ‘thinking machine’ to create something which would be far more revolutionary for society.
The internet is one big experiment, and you’re part of it. Every day, millions of trials are manipulating what you see when you browse online, to find out how to keep your attention, make you click more links – and spend more money. And these experiments are often secret. You’ll probably never know you were part of them.
This is all thanks to something now well-known in the tech industry, called A/B testing. It means that the web pages served to you are not necessarily the same as those shown to the next person – they might have slightly different colours, an alternate headline or, on social networks, you could be shown different personal information about your friends and family.
A US Department of Defense (DoD) research programme is funding universities to model the dynamics, risks and tipping points for large-scale civil unrest across the world, under the supervision of various US military agencies. The multi-million dollar programme is designed to develop immediate and long-term “warfighter-relevant insights” for senior officials and decision makers in “the defense policy community,” and to inform policy implemented by “combatant commands.”
Launched in 2008 – the year of the global banking crisis – the DoD ‘Minerva Research Initiative’ partners with universities “to improve DoD’s basic understanding of the social, cultural, behavioral, and political forces that shape regions of the world of strategic importance to the US.”
