China is developing a next-generation maglev system designed to reach 1,000 km/h by combining magnetic levitation with low vacuum tube travel. This video breaks down how it works, why it goes far ...

Chicago, Jan. 16, 2026 (GLOBE NEWSWIRE) -- The global vacuum blood collection tube market was valued at 3.24 billion in 2024 and is expected to reach US$ 4.40 billion by 2033, growing at a CAGR of ...

Older table-top AC-DC radios used a classic line-up of tubes. Think 12SA7, 12SK7,12SQ7, 35Z5GT, and 50L6GT. As I grew into my teens, I got interested in how these radios worked and soon discovered ...

Before transistors or microchips, the earliest computers relied on vacuum tubes — glass bulbs that glowed like small light bulbs and acted as electronic switches. Each tube could represent a one or ...

In a defence tech laboratory in Beijing, a research team powers up a vacuum tube about the size of a pistol. Inside, a stream of electrons surges through thin coiled wires, amplifying microwave pulses ...
