What is a Pulsar by Cihan News Agency (CNA). An international team of astronomers has used X-ray telescopes in space and ground-based telescopes, including two of CSIRO's, to identify a. that switches between emitting X-rays and emitting radio waves.
The Panasonic Toughbook CF-53 is a beefy laptop with a rugged design that goes from the street to the office and out to the field without breaking a sweat.
One model in particular caught my attention; it looks and feels similar to the ruggedized models, yet weighs only 3.7 pounds. With its built-in handle, it really defines what I think a business-rugged laptop should look like. The Toughbook F8 has a 14.1-inch screen with a DVD multi-drive inside a magnesium alloy case, and it's drop-and spill-resistant.
