Space experts were left astonished when they saw a video of Unidentified Flying Object (UFO) in the northern suburbs of Oregon and appeared to show a bright object drifting through the sunset.

Climate: No 'Plan B' for oceans, says study

Technology to drain heat-trapping CO2 from the atmosphere may slow global warming, but will not reverse climate damage to the ocean on any meaningful timescale, according to research published today.
