Catalyst Volume 24 Issue 4
This issue of Catalyst contains the following articles:
The Rosetta spacecraft is designed to catch up with, and explore, a comet.
The article looks at the career of Nick Treby who works around the world as an acoustic engineer, monitoring and managing sound levels in the environment.
The article investigates how biologists are developing artificial systems which mimic photosynthesis in order to produce fuels from sunlight.
Deep ocean vents are found along mid-ocean ridges. They are home to communities of unusual organisms.
The article looks at areas of peatland in the tropics, hosting communities of plants and animals not found elsewhere and how agricultural development poses a threat to them.
The article describes how fire engineers work to minimise the threat of fire and to protect people when fire breaks out.
The article describes how sexual selection, a form of natural selection, plays an important part in the evolution of many organisms.
The article investigates how scientists make images using colours to represent electromagnetic radiations which humans cannot see.
This Catalyst article looks at the Rosetta mission: to rendezvous with Comet 67P/Churyumov-Gerasimenko where it will study the nucleus of the comet and its environment for nearly two years, and land a probe on its surface. The article also describes how gravity assists, also known as slingshot manoeuvres, are used...
This Catalyst article investigates the research into artificial photosynthetic systems.
With the world’s population ever-expanding, energy demand is expected to double by 2050 and triple by 2100. In only 200 years, mankind has squandered what nature has taken hundreds of millions of years to lay down as...
This Catalyst article describes discovering hydrothermal vents at ocean sea-beds. Hydrothermal vents form along mid-ocean ridges. A mid-ocean ridge is where the Earth’s tectonic plates are moving apart, usually at a rate of about 6 to 18 centimetres a year. The presence of hydrothermal vents had been predicted by...
