11. Tumor-Blasting Endoscope Seeks And Destroys Cancer Cells 12/30/2014

    Often used to examine internal organs for tumors or other diseases, endoscopes may soon be used to treat cancer. Using new imaging methods and focused light beams, these devices may decrease side effects by delivering localized chemotherapy to tumors, thus improving treatment efficiency.

12. New GaN Fabrication Technique Could Enhance Biosensors 12/29/2014

    A recent discovery at North Carolina State University has revealed new ways of binding peptides to the surface of gallium nitride (GaN). The new binding method protects peptides, keeping them stable when exposed to water and radiation, and it could enable new biosensors for medical research applications.

13. Smartphone Microscope Detects, Measures Individual DNA Molecules 12/22/2014

    Researchers from UCLA’s California NanoSystems Institute have imaged and measured the sizes of individual DNA strands using a smartphone. Their newly developed, lightweight, and compact device cheaply transforms an off-the-shelf smartphone into a fluorescent microscope with advanced capabilities.

14. Lens-Free Microscope Could Lead To Cheaper, Portable Imaging Tech 12/19/2014

    Research from the University of California at Los Angeles (UCLA) has led to a new, lens-free microscope that can detect cellular abnormalities like cancer. The portable system has a similar accuracy to the larger, more expensive equipment often found in pathology labs, so it may enable diagnostics in more remote areas.

15. Zapping Vocal-Cord Cancer With Lasers Proven Effective In Long-Term Study 12/18/2014

    A pioneering laser treatment for early vocal-cord cancer has shown promise as a long-term cure for the disease. In addition to being as effective as traditional approaches at curing tumors, the treatment developed at Massachusetts General Hospital is also able to spare the patient’s vocal cords and ability to speak.

16. Researchers 3D Print LED Into Contact Lens 12/17/2014

    As a proof-of-concept for new 3D printing techniques, a Princeton team has developed a contact lens that projects beams of light. The researchers embedded a light-emitting diode (LED) into a contact lens, which demonstrated the flexibility and power of their new 3D printing approach.

17. Will Radio Telescopes Deliver The Image Of The Century? 12/15/2014

    An unprecedented worldwide collaboration has brought together a global network of radio telescopes to achieve an incredible level of image resolution. The objective of this effort is to image for the first time what some deem to be the most exotic object in the universe — a black hole’s event horizon.

18. Can Optogenetics Help Treat Epilepsy? 12/14/2014

    Using gene therapy techniques, researchers at the University of California Irvine (UC Irvine) have developed an optogenetic approach that allows them to monitor neuronal activity during and in between seizures. The new approach enables interactions with a single cell or entire networks of cells, and it could lead to the development of new therapeutic approaches for epilepsy.

19. Enabling Low-Cost Production Of 3D Nanostructures 12/12/2014

    Researchers from North Carolina State University have developed a new lithographic method that creates 3D nanostructures using nanospheres instead of more expensive, conventional methods. The technique eliminates the stacking of 2D patterns in the production of 3D structures and could find application in the biomedical, electronic, and photonic space.

20. Meet The World's Fastest 2D Camera 12/8/2014

    A new advance from Washington University in St. Louis has led to the world’s fastest receive-only 2D camera, which is capable of capturing 100 billion frames per second. New applications in fluorescent biomedicine are now possible, including the actual visualization of light on the fly.
