  • Nanoparticles could aid fast test for infectious diseases
    A screening method that uses DNA powder and gold nanoparticles has passed tests involving the identification of malaria and sexually transmitted diseases, researchers at the University of Toronto's Institute of Biomaterials and Biomedical Engineering reported in the journal Angewandte Chemie. The test is being developed as a fast point-of-care assay for the diagnosis of multiple infections from a single small sample. (3/5) LinkedInFacebookTwitterEmail this Story
  • "Bertha" being loaded onto a ship in Japan for Seattle trip
    Source: KING-TV
    The 5-story-tall tunnel-boring machine named "Bertha" is being loaded in 41 pieces onto a ship in Japan for its trip to Seattle. The machine, which is expected to arrive in the city later this month, will be used in the Alaskan Way Viaduct Replacement Program. Meanwhile, crews at the Seattle site are 80% finished with work on what will become a 400-foot-long, 80-foot-deep launch pit where the borer will be assembled.

  • Internal scaffolding guides body back to health
    Tiny scaffolds constructed from combinations of synthetic and biological material are being used in patients for a variety of purposes. Either through implantation or injection, they can help target cancer cells with drugs or assist the body in regrowing tissue and bone. It's the biological component of the latest hybrid scaffolds, however, that have enabled wider use by encouraging the appropriate cell growth as needed.

  • Heart pacemaker power source taps heartbeats
    Battery replacement for heart pacemakers has been addressed in a variety of ways, but a new method could offer a practical way to power the devices with the beating heart itself. The key to the device developed by Amin Karami and colleagues at the University of Michigan is its combination of a piezoelectric material and a magnet. This allows the device to harvest energy at nearly any heart speed, something the previous piezoelectric attempts could not manage.

  • Viable way found to grow brain cells in 3 dimensions
    Reproducing brain cells with the hope of aiding stroke or head trauma victims requires the ability to grow in three dimensions, something that has rarely been achieved in the lab. But researchers at Harvard and the Massachusetts Institute of Technology have found a way to do so at low cost, using brain cells suspended in hydrogels that can be sculptured to guide the cells' growth.

  • Fashion line appeals to anti-drone sentiment
    Metalized fabric is the key in a line of clothing designed to shield its wearers from the infrared detectors of drones. Urban guerrilla fashion designer Adam Harvey's Stealth Wear absorbs and scatters infrared light and in doing so makes the wearer harder to distinguish from his or her surroundings. Harvey's clothing items use copper, nickel and silver for stylish flair. (3/7) LinkedInFacebookTwitterEmail this Story

  • Ask "where" and "how" to plot a course for victory
    Strategic success comes down to answering these questions: Which playing field do you want to be on, and how will you achieve success once there, David Burkus writes. "If you know how to ask and answer these two questions properly, then you can cut through the confusion and craft a strategy that really works," he writes.

  • Aerial Robots: The Present and Future
    March 13 at 02:00 p.m. Eastern
    Autonomous micro aerial robots can operate in three-dimensional unstructured environments, and offer many opportunities for environmental monitoring, search and rescue, and first response. Dr. Vijay Kumar, UPS Foundation Professor at the University of Pennsylvania, and author of one of the most well-known TED talks in recent years, describes the challenges in developing small, agile robots, as well as his recent work in addressing these challenges.
