Starpower: Boost in quest for nuclear fusion

Scientists on Wednesday announced an important advance in the long quest to harness nuclear fusion, a field that has sparked dreams of clean and limitless energy. Fusion, the process that powers the Sun and other stars, entails forging the nuclei of atoms to release energy, as opposed to splitting them, which is fission -- the principle behind the atomic bomb and nuclear power. Decades of work in fusion have run up against a giant hurdle -- the energy yield from the reaction has been dwarfed by the vast amounts of energy needed to trigger the process.

'Oldest star' found from iron fingerprint

Australian astronomers on Sunday said they had found a star 13.6 billion years old, making it the most ancient star ever seen. The star was formed just a couple of hundred million years after the Big Bang that brought the Universe into being, they believe. Previous contenders for the title of oldest star are around 13.2 billion years old -- two objects described by European and US teams respectively in 2007 and 2013.

UK plant gets all-clear after radioactivity levels rise

Britain's Sellafield nuclear reprocessing plant was given the all-clear on Friday after "elevated" levels of radioactivity were detected. The plant in northern England had told all staff except for essential workers to stay home after its monitoring system picked up higher-than-normal radiation readings overnight. But operators Sellafield Ltd later said the higher readings were "naturally occurring background radon".

Astronomers 'see' strands of cosmic web

Astronomers said Sunday they had for the first time seen the gas strands theorised to hold the universe together in a "cosmic web". They had used the intense radiation generated by a quasar -- a byproduct of a supermassive black hole -- acting as a type of cosmic flashlight to illuminate part of the vast filament network. Cosmologists believe that matter between galaxies is distributed in a network of strands known as the cosmic web.

Cleveland Browns wide receiver Bess arrested in Florida

MIAMI (Reuters) - Cleveland Browns wide receiver Davone Bess was arrested on Friday at an airport in Florida and charged with assaulting a police officer, officials said. Bess, 29, was also charged with disorderly conduct and resisting arrest in an incident at the Fort Lauderdale airport. Bess posted $100 bail and was later released from jail. "We are aware of the situation and currently working to gather more information," said Browns spokesman Zak Gilbert.

Wave sweeps three family members out to sea in Spain

Rescuers found the body of a man Tuesday on Spain's northwestern coast where three members of the same family were swept out to sea by a huge wave while reportedly scattering the ashes of a dead relative. Police found the body on a beach on the rocky coast of Valdovino in Galicia, police said in a message on their Twitter account. Spanish media said the man was a 67-year-old who was swept out to sea along with his niece and his brother-in-law on Monday while they were standing on a cliff.

N-test legacy in stratosphere bigger than thought, study

Levels of radioactive plutonium in Earth's stratosphere from nuclear tests and accidents is higher than previously thought, but probably not dangerous to humans, scientists in Switzerland said Tuesday. It was previously thought that plutonium radionuclides -- radioactive atoms which can take decades or thousands of years to degrade -- were present in the stratosphere only at negligible levels. It was also believed that levels of these pollutants were higher in the troposphere, the layer of the atmosphere that is closest to the ground, than in the stratosphere.
