Scientists have discovered a new ring system around a dwarf planet on the edge of the Solar System. The ring system orbits much further out than is typical for other ring systems, calling into question current theories of how ring systems are formed.

The ring system is around a dwarf planet, named Quaoar, which is approximately half the size of Pluto and orbits the Sun beyond Neptune.

The discovery, published in Nature, was made by an international team of astronomers using HiPERCAM — an extremely sensitive high-speed camera developed by scientists at the University of Sheffield which is mounted on the world’s largest optical telescope, the 10.4 metre diameter Gran Telescopio Canarias (GTC) on La Palma.

The rings are too small and faint to see directl...

Researchers at the University of East Anglia have helped develop a new blood test to detect prostate cancer with greater accuracy than current methods.

New research shows that the Prostate Screening EpiSwitch (PSE) blood test is 94 per cent accurate — beating the currently used prostate-specific antigen (PSA) blood test.

The research team say that the new test shows significant potential as an accurate and rapid cancer screening diagnostic.

The test was developed by Oxford Biodynamics in collaboration with UEA, Imperial College London and Imperial College NHS Trust.

Prof Dmitry Pshezhetskiy, from UEA’s Norwich Medical School, said: “Prostate cancer is the most common cancer in men and kills one man every 45 minutes in the UK.

“There is currently no single te...

Hydrogen fuel could be a more viable alternative to traditional fossil fuels according to University of Surrey researchers who have found that a type of metal-free catalysts could contribute to the development of cost-effective and sustainable hydrogen production technologies.

The study has shown promising results for the use of edge-decorated nanocarbons as metal-free catalysts for the direct conversion of methane, which is also a powerful greenhouse gas, into hydrogen. Among the nano carbons investigated, nitrogen-doped nano carbons presented the highest level of performance for hydrogen production at high temperatures.

Crucially, the researchers also found that the nitrogen-doped and phosphorus-doped nano carbons had strong resistance to carbon poisoning, which is a common is...

New research from the University of Georgia reveals that artificial intelligence can be used to find planets outside of our solar system. The recent study demonstrated that machine learning can be used to find exoplanets, information that could reshape how scientists detect and identify new planets very far from Earth.

“One of the novel things about this is analyzing environments where planets are still forming,” said Jason Terry, doctoral student in the UGA Franklin College of Arts and Sciences department of physics and astronomy and lead author on the study...
