Lasers Keep Crows Out Of The Corn
From mid-July through October, just as New England sweet corn crops ripen, flocks of blackbirds, starlings, grackles and crows swarm and strip the fields, inflicting up to $800 in lost product per acre. And deterrent methods were not ideal. That is why the Rhode Island Department of Environmental Management asked Rebecca Brown, a professor of plant sciences at the University of Rhode Island in Kingston, R.I., to study the effectiveness of a laser-based alternative at small farms.

OCT-A Detects Early-Stage Glaucoma
Optical coherence tomography angiography (OCT-A) was used at the earliest stages of glaucoma to identify the characteristic patterns of different forms of the disease. OCT-A, a noninvasive technique that employs en face reconstruction of OCT combined with motion contrast processing to reveal perfused retinal vasculature, could enable doctors to diagnose glaucoma cases earlier than ever before and potentially slow down the progression of the disease.

A $1.4 million, three-year grant from the National Institute of Mental Health (NIMH) of the National Institutes of Health (NIH) has been awarded to Dr. Ryohei Yasuda, scientific director at the Max Planck Florida Institute for Neuroscience (MPFI) and collaborator Dr. Wenbiao Gan, professor at the NYU Langone Medical Center.

An eight channel smartphone spectrometer has been developed that can detect human interleukin-6 (IL-6), a known biomarker for lung, prostate, liver, breast and epithelial cancers. Unlike current smartphone spectrometers, which are used to monitor or measure one sample at a time, the multichannel smartphone spectrometer (MSS) can optically analyze several samples simultaneously, adding to its potential value as a high-throughput device.

High-Speed Imaging At and Beyond the Diffraction Limit
Thu, Feb 16, 2017 1:00P EST
Hari Shroff, Ph.D., head of the Section on High Resolution Optical Imaging at the National Institute of Biomedical Imaging and Bioengineering (NIBIB), will speak on his lab's latest work to develop high-resolution optical methods for the study of live, dynamic, 3D samples, including efforts to improve structured illumination microscopy (SIM) and light-sheet microscopy. He will also discuss developments in inverted selective plane illumination microscopy (iSPIM) and dual-view iSPIM.
