• Researchers at the New Jersey Institute of Technology (NJIT) recently announced they have pioneered a nano-chip that could change how we find out if we’re sick.

    The device, a carbon nanotube-based chip designed by Prof. Reginald Farrow, Prof. Alokik Kanwal and their team, will allow medical personnel to measure a cell’s electrical property on a micron scale – about one hundredth of a human hair. A cell’s electrical charge is an important sign post because it changes when a cell becomes sick.

    The scientists say this lays the foundation for an inner-body “lab-on-a-chip” that could monitor for the presence of foreign cells belonging to bacteria and viruses. Prof. Kanwal believes these sensors could be made to report information, like the presence of disease, to a wrist watch.

    “So, imagine you wake up in the morning and you have a sore throat,” said Prof. Kanwal, “Normally we just go to the doctor. But we’d like for you to tap your watch instead. It could tell you ‘You have this

  • Sure, 3-D printers can print pretty much any three-dimensional object you can think of - but can they print in zero gravity?

    That’s what NASA wants to find out next year when it tests a 3-D printer on the International Space Station. So far, the printer, which NASA created with Made In Space, a California-based company, has successfully printed small computer parts in parabolic flights that simulate zero gravity. But the next step is to actually test a 3-D printer in space.

    “We want to show that not only can we print, but when we print these tools they have same comparable quality as printing on Earth,” said Niki Werkheiser, project lead for 3-D printing in zero-G ISS technology demonstration at NASA’s Marshall Space Flight Center.

    The printer works like existing 3-D printers: It heats and melts plastic and then pours it, layer by layer, until the object is formed. Currently, if an astronaut loses or breaks an item on the International Space Station, he or she must wait until a

  • The High-Tech Trailer of Your Dreams

    Last week, at the annual Dusseldorf Caravan Salon in Germany, one trailer made its mark by not resembling a typical trailer. A luxurious boat, or space ship, would make for a better comparison.

    Introducing the Caravisio (“Cara” for Caravan; “Visio” for vision), the trailer of the future.

    Fabricated by German campervan-maker Knaus Tabbert, the Caraviso packs such technical features as a full HD projector in the ceiling, a finger scan security system that renders keys obsolete and a rear veranda. For a full tour, watch the accompanying video above.

    “Most caravans, you know, they are very conservative,” said Wolfgang Speck, CEO of Knaus Tabbert,” so we said, therefore, we have to do something completely different.”

    “Completely different” translates to flowing walls without right-angle corners, “air-spring” suspension that lowers the trailer to the ground and window shades that can be controlled with your tablet device.

    So far, the Caravisio is a promotional vehicle and not slated for
