Training talent to hit a moving target Unlike conventional sectors — such as manufacturing, health care, or agriculture — that base their value on quantifiable production, the value of photonics is better measured by a more qualitative metric. Its value compares less to the square footage of a house and more to the scenery and light provided by the house’s windows. Put another way, the best measure of...

Choosing a Microscope Camera: Factors to Consider As remote sharing becomes popular in the microscopy world, it is more important than ever to be able to translate the images that the eye sees into something that can be reliably visualized on a screen. Choosing the right digital microscope camera requires a basic understanding of imaging sensor types, how their performances differ, and the external factors that affect the images acquired.

Lidar reveals the hottest properties for a Western Australian lizard A number of indicators point to the cooling of the real estate market. Interest rates are ticking up. Inventory is growing. Sellers are cutting prices. In Western Australia — one of the literally, if not figuratively, hottest housing markets — homeseekers such as the Western spiny-tailed skink (Egernia stokesii badia) appear to be increasingly selective about their housing options....
