The FAA has reported that an "unknown object" struck a Piper Apache while in flight near Romeoville, Illinois, but according to the drone website suasnews.com, that object was likely a small drone. Citing an "unconfirmed report," suasnews states that a Piper PA-23 twin impacted the drone at about 2,500 feet near Lewis University Airport (KLOT) in Illinois on August 27. Photos of damage on the aircraft appear to show a series of vertical indentations and a slice into the rubber de-ice boot along the leading edge of the tail surface. The airplane landed safely and nobody was hurt.
Advances in 3-D printing have led to new ways to make bone and some other relatively simple body parts that can be implanted in patients. But finding an ideal bio-ink has stalled progress toward printing more complex tissues with versatile functions -- tissues that can be loaded with pharmaceuticals, for example. Now scientists have developed a silk-based ink that could open up new possibilities toward that goal.
Researchers from Columbia Engineering and Columbia University Medical Center (CUMC) have developed a new method that can target delivery of very small volumes of drugs into the lung. Their approach, in which micro-liters of liquid containing a drug are instilled into the lung, distributed as a thin film in the predetermined region of the lung airway, and absorbed locally, may provide much more effective treatment of lung disease. The work was published in the August 31 online Early Edition of Proceedings of the National Academy of Sciences (PNAS).
