• Tiny probe that senses deep in the lung set to shed light on disease June 17, 2019
  A hair-sized probe that can measure key indicators of tissue damage deep in the lung has been developed by scientists.
• MIT and NASA engineers demonstrate a new kind of airplane wing April 1, 2019
  A team of engineers has built and tested a radically new kind of airplane wing, assembled from hundreds of tiny identical pieces. The wing can change shape to control the plane's flight, and could provide a significant boost in aircraft production, flight, and maintenance efficiency, the researchers say.
• When Concorde first took to the sky 50 years ago March 1, 2019
  When the misty skies cleared over southern France on the afternoon of Sunday March 2, 1969, the green light was signalled for the highly anticipated first ever flight of the Concorde.
• Paper sensors remove the sting of diabetic testing December 21, 2018
  A technique that enables biologically active enzymes to survive the rigors of inkjet printing presents a promising alternative to routine blood screening finger jabs for diabetic blood sugar levels. The KAUST-led team used this approach to make disposable devices that can measure glucose concentrations in human saliva.
• Micropores let oxygen and nutrients inside biofabricated tissues December 20, 2018
  Micropores in fabricated tissues such as bone and cartilage allow nutrient and oxygen diffusion into the core, and this novel approach may eventually allow lab-grown tissue to contain blood vessels, according to a team of Penn State researchers.
• Understanding dynamic stall at high speeds December 18, 2018
  When a bird in flight lands, it performs a rapid pitch-up maneuver during the perching process to keep from overshooting the branch or telephone wire. In aerodynamics, that action produces a complex phenomenon known as dynamic stall. Although many fixed-wing aircraft can withstand similar rapid pitch-up maneuvers, a vehicle subject to this dynamic stall process […]
• Pushing lithium ion batteries to the next performance level December 13, 2018
  Conventional lithium ion batteries, such as those widely used in smartphones and notebooks, have reached performance limits. Materials chemist Freddy Kleitz from the Faculty of Chemistry of the University of Vienna and international scientists have developed a new nanostructured anode material for lithium ion batteries, which extends the capacity and cycle life of the batteries. […]
• To guide cancer therapy, device quickly tests drugs on tumor tissue December 12, 2018
  MIT researchers have 3-D printed a novel microfluidic device that simulates cancer treatments on biopsied tumor tissue, so clinicians can better examine how individual patients will respond to different therapeutics—before administering a single dose.
• Researchers devise 3-D printer that can make energetic materials safer, more environmentally friendly December 7, 2018
  Purdue University researchers have devised a method of 3-D printing that can produce energetic materials with fine geometric features faster and with less expense than traditional methods, while also being safer and more environmentally friendly.
• How engineers are straightening the Leaning Tower of Pisa December 2, 2018
  "It's still straightening," said engineer Roberto Cela, gazing at the Leaning Tower of Pisa gleaming in the autumn sunshine of northern Italy. "And many years will have to pass before it stops."
