Carbon Capture

A Catalyst article explaining how carbon capture and storage can reduce the amount of carbon dioxide entering the atmosphere and may reduce the effects of climate change. Burning fossil fuels releases carbon dioxide into the atmosphere. This is a major contributor to climate change but can CO2 be captured and...

Mission to Mercury

A Catalyst article about BepiColombo, a spacecraft which will visit Mercury, powered by a revolutionary new rocket engine technology using ion engines and using a slingshot manoeuvre to accelerate it. The development of the spacecraft is an international project and will combine exciting scientific goals exploring...

Infra-red Astronomy

A Catalyst article describing how the VISTA telescope, which is located in Chile, works. It detects infrared radiation - electromagnetic radiation beyond the red end of the spectrum. This has two great benefits:

*The telescope can detect radiation from distant stars which are otherwise hidden behind clouds...

Hearing Trouble

This Catalyst article looks at 'Restored Hearing', a business which grew out of a school science project. It provides therapy for sufferers of temporary tinnitus, a debilitating hearing condition caused by exposure to loud noises. The article looks at how hearing loss can occur and how also explains how the...
