What the US CHIPS Act left out After lingering for two years in legislative gridlock, the CHIPS and Science Act of 2022 was finally passed by both the Senate and the House of Representatives in July. President Biden quickly signed it into law, and early last month the Department of Commerce published its strategy for implementing the $52 billion that the bill designated to restore momentum to the nation’s domestic...

Laser Safety
Laser Warning Lights: From Red Bulbs to Holograms From the very first use of lasers, a key safety practice has involved providing some type of indication to alert people that they are about to enter a room where a laser is on or powered up. Further emission indicators on the laser, its power supply, or both, are also routine. The ANSI standard Z136.1 for Safe Use of Lasers states: A Class 3B Laser Control Area (LCA) should and a Class 4 LCA...

Could lasers put cold brew on a hot streak? Not all that is cold is cool. Cold brew coffee, for example, is simply better than iced hot brew. If you don’t believe the studied opinions of millions of hipsters and millennials, then believe Technavio Research, which recently projected that the cold brew coffee market will grind out more than 26% compound annual growth between 2020 and 2025. If there’s one burnt bean that could sour this...
