New Imaging Approach Maps Whole-Brain Changes from Alzheimer’s Disease in Mice
An estimated 5.5 million Americans live with Alzheimer’s disease, a type of dementia that causes problems with memory, thinking and behavior. Although treatments can slow the worsening of symptoms, scientists are still working to better understand the neurodegenerative disease so that curative and preventative medicines can be developed. A new imaging system could help speed new drug development by offering a better way to monitor the brain changes indicative of Alzheimer’s in mouse models of the disease.

In a first for wearable optics, researchers develop stretchy fiber to capture body motion
The exciting applications of wearable sensors have sparked a tremendous amount of research and business investment in recent years. Sensors attached to the body or integrated into clothing could allow athletes and physical therapists to monitor their progress, provide a more detailed level of motion capture for computer games or animation, help engineers build robots with a lighter touch or form the basis for new types of real-time health monitors.

Freeze Frame Microscopy for 3D Biological Images Captures 2017 Nobel Prize in Chemistry
“The Nobel Committee’s recognition of yet another type of biomedical imaging underscores just how important, and enabling imaging and microscopy techniques are to all areas of science and medicine,” stated Elizabeth M.C. Hillman, professor of Biomedical Engineering at Radiology, Columbia University, and general chair of the upcoming 2018 OSA BioPhotonics Congress.

Unlocking the Secrets of the Universe; LIGO Team Awarded 2017 Nobel Prize in Physics
Astrophysicists have long sought to detect ripples in space-time, called gravitational waves, since Albert Einstein’s 1916 prediction of General Relativity. But only some of the most massive astrophysical events, such as mergers of black holes and neutron stars, can produce gravitational waves strong enough to be detected on earth. Today, the 2017 Nobel Prize in Physics was awarded to Barry C. Barish and Kip S. Thorne, California Institute of Technology, USA and Rainer Weiss, Massachusetts Institute of Technology, USA, "for decisive contributions to the LIGO detector and the observation of gravitational waves."

DNA: The next hot material in photonics?
Using DNA from salmon, researchers in South Korea hope to make better biomedical and other photonic devices based on organic thin films. Often used in cancer treatments and health monitoring, thin films have all the capabilities of silicon-based devices with the possible added advantage of being more compatible with living tissue.

Circadian Rhythms, the Body's Natural Time-Keeping System, Awarded 2017 Nobel Prize
Most of the processes that occur in the mind and body follow natural rhythms. Those with a cycle length of about one day are named circadian rhythms. The 2017 Nobel Prize in Physiology or Medicine was awarded today to Jeffrey C. Hall and Michael Rosbash of Brandeis University, USA and Michael W. Young, Rockefeller University, USA, "for their discoveries of molecular mechanisms controlling the circadian rhythm."

The Optical Society Congratulates the LIGO and Virgo Scientific Collaboration for Fourth Gravitation
Albert Einstein’s 1916 general theory of relativity was validated for a fourth time according a joint announcement between the international LIGO and Virgo Scientific Collaborations. Only some of the most massive astrophysical events, such as mergers of black holes and neutron stars, can produce gravitational waves strong enough to be detected on earth. On August 14, the Virgo Collaboration, along with the U.S. LIGO observatories, detected its first gravitational wave signal from a pair of black holes violently merging over a billion light-years away. LIGO’s previous detections have stemmed from merging black holes but this is the first time a merger has been witnessed by three observatories at one time.

The Mars 2020 Rover Features New Spectral Abilities with its New SuperCam
As the NASA Curiosity rover roams the surface of Mars, its ChemCam captures the chemical makeup of its surroundings with a specially designed laser system. It is the most powerful laser to operate on the surface of another planet. The burst of infrared light it fires lasts only a few billionths of seconds, but it is powerful enough to vaporize the spot it hits at more than 8,000°C. Even from a distance, the ChemCam can examines rocks and soil using a process called Laser Induced Breakdown Spectroscopy (LIBS), where laser bursts atomize and excite components and spectral images capture their chemical signatures.
