Manchester United: How Ole Gunnar Solskjaer turned around a toxic atmosphere

Sports
Ole Gunnar Solskjaer could hardly have done any better in his first 11 games as Manchester United's caretaker manager.What happens in the next 11 - starting against Paris St-Germain in the Champions League on Tuesday - will probably determine whether the 45-year-old Norwegian gets the job of replacing Jose Mourinho full-time.But off the pitch, he has hit the reset button at Old Trafford, restoring the ethos of Sir Alex Ferguson's trophy-laden time in charge. In eight short weeks, Solskjaer has wiped out the toxic atmosphere of Mourinho's final few weeks at Old Trafford - and United fans are enjoying going to watch their team again.So how has he done it? The personal touchIn 14 years as a play...
Air pollution can chemically transform organic vapors in the atmosphere

Air pollution can chemically transform organic vapors in the atmosphere

Science
Dec. 14 (UPI) -- Scientists are only just beginning to understand the complex ways new aerosol particles form in the atmosphere. New research suggests human-caused air pollution can impact the conversion of organic gasses into aerosols. All ecosystems, including wetlands, forests and mountain streams, emit organic compounds into the atmosphere, but only a few of these compounds are known to react with atmospheric gases to form particles, or aerosols. When researchers monitored particle formation in the lab, they found aerosols formed most efficiently when sulfuric acid, ammonia and organic vapors were all present. Increased nitrogen oxide levels were associated with lower rates of aerosol formation. Researchers designed their lab conditions to mimic the atmosphere above the Finnish boreal...
Saturn's inner rings are raining chemicals on its atmosphere

Saturn's inner rings are raining chemicals on its atmosphere

Science
Oct. 5 (UPI) -- New analysis of observations made during the Cassini's "Grand Finale" plunge suggests Saturn's rings are surprisingly complex in their chemical composition. The data also suggests chemical-coated dust grains from Saturn's innermost D ring are raining down on the gas giant's upper atmosphere. Over time, scientists predict, the flow of chemicals could alter the composition of Saturn's atmosphere. During its final pass through Saturn's rings and into the planet's atmosphere, Cassini's spectrometer sampled and analyzed a variety of chemicals. The instrument's data revealed the surprising presence of water, methane, ammonia, carbon monoxide, molecular nitrogen and carbon dioxide. Researchers shared their survey of the Cassini data this week in the journal Science. "What the pa...
Viruses raining down from Earth's atmosphere

Viruses raining down from Earth's atmosphere

Technology
Scientists have discovered that millions of viruses are travelling around the Earth's atmosphere.The viruses are transported up on the back of organic particles suspended in air and gas - and then rain down upon the ground.This could explain how genetically identical viruses can be found enormous distances apart - by hitching a ride on smaller particles swept up into the atmosphere.Scientists from universities in Canada, Spain and the US have also, for the first time, quantified the number of viruses that are being swept up from the ground into the atmosphere.The number is huge, stretching into the billions per square metre.While the viruses and bacteria aren't reaching the heights of the stratosphere, they are being lifted way above the zone in which weather conditions are taking place.Th...
Cassini skims Saturn's atmosphere

Cassini skims Saturn's atmosphere

Science
The Cassini probe has begun the final phase of its mission to Saturn. The satellite has executed the first of five ultra-close passes of the giant world, dipping down far enough to brush through the top of the atmosphere. It promises unprecedented data on the chemical composition of Saturn. It also sets the stage for the probe's dramatic end-manoeuvre next month when it will plunge to destruction in the planet's atmosphere. Cassini is currently flying a series of loops around Saturn that thread the gap between its atmosphere and its rings. Monday's swing-by saw the spacecraft go closer than ever before to the cloud tops - skimming just 1,600km (1,000 miles) above them, at 04:22 GMT (05:22 BST) on Monday. This low pass was designed to allow the probe to directly sample the gases of the exte...
