A flexible detector for terahertz frequencies (1,000GHz) has been developed using graphene transistors on plastic substrates. It is the first of its kind, and can extend the use of terahertz technology to applications that will require flexible electronics, such as wireless sensor networks and wearable technology. Terahertz radiation has a wide range of uses from radio astronomy to medicine...

A giant planet, which should not exist according to planet formation theory, has been discovered around a distant star. The existence of the ‘monster’ planet, ‘NGTS-1b’, challenges theories of planet formation which state that a planet of this size could not be formed around such a small star. According to these theories, small stars can readily form rocky planets but do not gather enough material together to form Jupiter-sized planets.

‘NGTS-1b’ however, is a ‘gas giant’ – due to its size and temperature, the planet is known as a ‘hot Jupiter’, a class of planets that are at least as large as our solar system’s very own Jupiter, but with around 20% less mass...

Scientists from The Open University (OU) have discovered a process that could explain the long-debated mystery of how land features on Mars are formed in the absence of significant amounts of water...

The new sustainable catalyst ‘splits’ water molecules to obtain hydrogen and oxygen needs very low voltages to work, and avoids the use of precious metals like iridium. Electrolysis, splitting the water molecule with electricity, is the cleanest way to obtain hydrogen, a clean and renewable fuel. Now, researchers at ICIQ and URV, led by Prof. José Ramón Galán-Mascarós, designed a new catalyst that reduces the cost of electrolytic hydrogen production. Catalysts reduce the amount of electricity needed to break the chemical bonds, speed up the reaction and minimise the energy waste.

‘Normally, hydrogen is obtained from using a cheap process called steam reforming...
