Can light-colored rooftops and roads really curb carbon emissions and combat global climate change?

The idea has been around for years, but now, a new study by researchers at Lawrence Berkeley National Laboratory that is the first to use a global model to study the question has found that implementing cool roofs and cool pavements in cities around the world can not only help cities stay cooler, they can also cool the world, with the potential of canceling the heating effect of up to two years of worldwide carbon dioxide emissions.

Photo Proof: Super Stars of the Universe Have Humble Beginnings

ANN ARBOR, Mich.—The first close-up picture of a nascent super massive star and its surroundings has shown that the highest mass stars in the universe form just like their smaller counterparts. They are born from swirling disks of gas and dust, rather than from violent stellar collisions.

“How these high mass stars form has been a debate for 20 years,” said Stefan Kraus, a research fellow in the University of Michigan Department of Astronomy who is first author of a paper on the findings published July 15 in Nature.

Eyjafjallajökull. While some say it is “unpronounceable”, it would be a good idea to get used to the name because for sure it is going to be around the international media for a long time to come.

Heroin, Cocaine, Marijuana. You know them all. They are just brothers and sisters, and belong to one big and powerful family (commonly known as drugs, or druggs etc.).

May be you would like to ask, “OK, it’s a family, then who is the father”.
