                           BAE System's mystery drone

  
          In a teaser of things to come, BAE Systems has displayed a model of its future drone at the World Defense Show in Riyadh. Steeped in more mystery than a Raymond Chandler novel, it gives us a hint of what future military drones might look like.
         International defense shows can often be more like bird watching events than showcases for the latest military hardware. Defense contractors don't just like to show off their wares for sale, they also like to give a glimpse of what might be on the way. Oftentimes, these will be in the form of models or concept images on display without any explanation of what they are.

                               Gravity has announced that the world's first jet suit race is slated for February 28, in Dubai

    Gentlemen, start your turbines – it's time to see how these spectacular next-gen personal flight devices look and perform in the fire of competition. Gravity Industries has announced the world's first jet suit race is happening in less than a month.
    They say the first motorcycle race happened the day the second motorcycle was built. It's taken a little longer for jet suits – we first covered Gravity founder Richard Browning's early forays into Iron-Man-style jet suits nearly seven years ago.

                                  A new study swaps sand for graphene to make lighter, more environmentally friendly concrete

   When you think of resources we’re running out of, sand might not be high on your list, but it’s up there thanks to our high demand for concrete. Scientists at Rice University have now shown that substituting graphene can not only save sand, but makes concrete lighter, stronger and tougher.
    Despite being a sheet of carbon atoms just one atom thick, graphene has a reputation for being incredibly strong. As such, it’s no surprise that this 'wonder material' has been mixed into concrete before, usually to make it stronger and more durable. But that usually involves just adding graphene to the recipe – for the new study, the Rice team wanted to replace sand completely.

                           The prototype filter – dirty water in, clean water out

     While we've seen quite a few filtration systems for making polluted water drinkable, many are quite complex, or utilize costly materials. By contrast, an experimental new setup simply requires users to inject dirty water through a layer of cellulose.
    Developed by scientists from The University of Texas at Austin, the prototype device consists of a roughly hockey-puck-shaped housing, inside of which is a hydrogel film supported by a membrane full of microscopic pores.
The hydrogel is in turn made up of "an intertwined web" of cellulose nanofibers. Cellulose is the most common organic compound on Earth – it can be easily and inexpensively obtained from a wide variety of readily available natural sources, such as plants.
