Opsins Travel to the Brain’s Hidden Places
The brain is one of the most complex systems in the known universe, a living computer that controls not only basic functions of the body but ponders and directs responses to what’s going on in its surroundings. But when it comes to understanding how the brain works — and, in some cases, how to heal what is ailing it — practitioners of optogenetics know that the answer can lie in natural optical phenomena that have existed since before modern life even began.

Blue Light Can Improve Sleep, Help Brain Recover from Injury
According to a University of Arizona study, exposure to blue light in the morning could re-entrain the circadian rhythm and improve sleep problems, leading to faster recovery from brain injury. Research has shown that the brain repairs itself during sleep. The team sought to determine whether improved sleep could lead to a faster recovery from mild traumatic brain injury.

A Laser Points Toward Disease Diagnosis
According to the latest reports from the United Nations Department of Economic and Social Affairs and the World Health Organization, life expectancy has more than doubled in the last two centuries, from less than 30 years to over 70, thanks to both life-saving scientific innovations and health improvements. But the rise in life expectancy increases issues of morbidity, primarily driven by the high prevalence of chronic diseases, such as cardiovascular disease, cancer, diabetes, and arthritis. This has serious consequences for nations’ health and health care systems.

Ultra Precise Piezo-Z Focus Stage
Applied Scientific Instrumentation Inc.
The PZ-2000FT XYZ stage has been specifically designed to provide a high resolution, and highly repeatable, means of controlling the X, Y, and Z position of the microscope stage. The XY axes derive their precise control through the use of closed-loop DC servomotors employing high-resolution rotary encoders for positioning feedback.

Smartphone-Based System Tests for Infectious Diseases, Sends Results to Doctor
Engineers at the University of Cincinnati (UC) have created a tiny portable lab that plugs into a smartphone. The lab, which is about the size of a credit card, can diagnose infectious diseases such as coronavirus, malaria, HIV, or Lyme. It can also track hormones related to anxiety or depression. The patient puts a single-use plastic lab chip into his or her mouth and the saliva on the chip is tested. The device automatically transmits test results to a doctor’s office through a custom app developed at UC.

University of California, Berkeley, researchers have built a microscope that can image the brain of an alert mouse 1000 times a second and record the passage of millisecond electrical pulses through neurons. The new imaging technique combines two-photon fluorescence microscopy and all-optical laser scanning in a microscope that can image a 2D slice through the neocortex of the mouse brain up to 3000 times per second. According to the researchers, that’s fast enough to trace electrical signals flowing through brain circuits.

Raman Spectroscopy: Theory, Practice, and Applications
Wed, May 6, 2020 1:00 PM - 2:00 PM EDT
This webinar, presented by Hamamatsu Corp., will review the basic theory behind normal, resonant, and surface-enhanced Raman scattering. It will discuss the hardware required in a working Raman spectrometer; describe data analysis and presentation; and give examples of common applications. In addition, it will examine some of the market challenges and solutions. You will learn about the basic setup of a Raman spectrometer, performance trade-offs associated with hardware limitations, and the factors that influence the choice of the illumination laser.
