Civilizations From Oldest Stars Had Enough Time To Reach Earth If They Wanted To: Researchers. Washington: If alien life really exists, they would have found humans by now, but consciously avoiding us for unknown reasons, a new study has suggested. Researchers, who calculated the time a society would take to muster up resources and know-how to travel to another world, found that alien civilizations starting from the oldest stars in the galaxy would have had more than enough time to reach Earth.

Every time petrol prices rise, people start buying diesel-powered vehicles, which add to toxic pollution in our cities

Consider this. Every time petrol prices rise, oil companies end up losing more money. How? The price differential between petrol and diesel increases further; people start buying diesel-powered vehicles so oil firms bleed more. Even worse, we all bleed because dieselisation adds to toxic pollution in our cities. This, in turn, adds to the health burden and costs.

New Delhi: After the early 2000s, when Delhi’s air became dramatically clean after the introduction of CNG in public transport, it has once again turned into a deadly cocktail of various pollutants. High levels of particulate matter (PM) that fired the original ‘clean air’ campaign 15 years ago, are no longer the only problem confronting policy makers. Levels of ozone, a product of the breakdown of oxides of nitrogen (NOx) in sunlight — and a major cause of respiratory problems — have been going up over the years.

New Delhi: The system for air quality forecasting and research (SAFAR) that was used to monitor and forecast air quality and weather conditions at various venues during the Commonwealth Games last October is now being installed across the city.
