Getting Hold of Quantum Dot Biosensors
Quantum dots (QDs) have found so many applications in recent years, they can now be purchased with a variety of composite structures and configurations. Some are available suspended in a biologically friendly fluid, making them well poised to serve as biomarkers for single-molecule tagging and tracking. But suppose you wanted to trap and move one of these single nanoparticle tags the same way other biologists might grab tissue samples with a tweezer?

Guide Star Alliance Team Receives OSA’s 2017 Paul F. Forman Team Engineering Excellence Award
The Optical Society (OSA) is pleased to announce that Guide Star Alliance is the winner of the 2017 Paul F. Forman Team Engineering Excellence Award. Under contract of and in close collaboration with the European Southern Observatory (ESO), industrial partners, TOPTICA Photonics and MPB Communications (MPBC), joined together to develop a high-power CW tunable laser system called the SodiumStar. The team’s development is now considered the quasi-standard for existing and planned telescopes around the world. The Guide Star Alliance will receive the award on 18 September 2017, during Frontiers in Optics (FiO) + Laser Science (LS) in Washington DC, USA.

New Terahertz Imaging Approach Could Speed Up Skin Cancer Detection
Researchers have developed a new terahertz imaging approach that, for the first time, can acquire micron-scale resolution images while retaining computational approaches designed to speed up image acquisition. This combination could allow terahertz imaging to be useful for detecting early-stage skin cancer without requiring a tissue biopsy from the patient.

New Tool Aims to Make Surgery Safer by Helping Doctors See Nerves
During operations, it can be difficult for surgeons to avoid severing crucial nerves because they look so much like other tissue. A new noninvasive approach that uses polarized light to make nerves stand out from other tissue could help surgeons avoid accidentally injuring nerves or assist them in identifying nerves in need of repair.

Relativistic Self-Focusing Gives Mid-IR Driven Electrons a Boost
Conventional particle accelerators can range from large room-sized devices to facilities multiple kilometers across. One of the ways that scientists have looked to reduce the size and expense of future accelerators is by developing laser –driven plasma acceleration. Such accelerators, however, are growing in size and complexity in order to maintain relevance for one of their applications—high energy physics. However, there are many applications that can use a lower energy and higher repetition rate accelerated beam. For the first time, scientists have observed the production of relativistic electrons driven by low-energy, ultrashort mid-infrared laser pulses.

New Optical Method Pinpoints Weak Spots in Jet Engine Thermal Coatings
Researchers have demonstrated, for the first time, that an optical analysis method can reveal weak areas in ceramic thermal barrier coatings that protect jet engine turbines from high temperatures and wear. The technique could be used to predict how long coatings would last on an airplane and might eventually lead to new thermal barrier coatings, making engines more efficient and cutting both the cost and pollution of air travel.

The Optical Society Foundation Concludes Successful 2017 Innovation School
The Optical Society Foundation (OSAF) hosted early-career professionals during its first Innovation School from 23-27 July at OSA headquarters in Washington DC. The four-day program focused on honing ‘intrapreneurial’ skills through a series of interactive ‘ideation and customer validation’ exercises. In addition, the hands-on program was accompanied by presentations led by CEO’s, entrepreneurs and innovation leaders in the optics and photonics industry.

Sophisticated Medical Imaging Technique Proves Useful for Automotive Industry
Many of today’s cars are coated with paint that exhibits a metallic or glittery shine. The exact sparkle and color you see is determined by the distribution and characteristics of tiny metal flakes used in the paint. A new approach based on the medical imaging technique optical coherence tomography (OCT) provides the car industry with a practical way to automatically analyze these metal flakes, which until now have been difficult to image, in order to improve the efficiency of the automotive finishing process.
