research outlines the story of soot
2014-07-02 03:36:39

Lawrence Berkeley National Laboratory Researchers at the Department of Energy’s Lawrence Berkeley National Lab (Berkeley Lab) and the University of Hawaii have uncovered the first step in the process that transforms gas-phase molecules into solid particles like soot and other carbon-based compounds. The finding could help combustion chemists make more-efficient, less-polluting fuels and help materials scientists fine-tune their carbon nanotubes and graphene sheets for faster, smaller...

Organic Conundrum In Milky Way’s Satellite Galaxy, The Large Magellanic Cloud
2014-06-23 03:03:26

Royal Astronomical Society A group of organic chemicals that are considered carcinogens and pollutants today on Earth, but are also thought to be the building blocks for the origins of life, may hold clues to how carbon-rich chemicals created in stars are processed and recycled in space. Scientists have studied how polycyclic aromatic hydrocarbons (PAHs) are created in an aging population of stars in the Milky Way’s satellite galaxy, the Large Magellanic Cloud. They have found that...

Marinate Meat In Beer Before Grilling To Help Reduce Harmful Substances
2014-03-27 07:24:07

American Chemical Society The smells of summer — the sweet fragrance of newly opened flowers, the scent of freshly cut grass and the aroma of meats cooking on the backyard grill — will soon be upon us. Now, researchers are reporting that the very same beer that many people enjoy at backyard barbeques could, when used as a marinade, help reduce the formation of potentially harmful substances in grilled meats. The study appears in ACS' Journal of Agricultural and Food Chemistry....

[ Watch the Video: New Technique For Studying Out-Of-This-World Particles ] Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists have long delved into the mysteries of the origins of life here on Earth and more recently have found evidence pointing to the skies above us. Some evidence has been found in material created in space and delivered to Earth via comets and meteors, containing the building blocks for life. The latest round of evidence comes by way of Michael...

The protocol, titled Conducting Miller-Urey Experiments, is comprised of a modern and simplified approach to the method used by Dr. Stanley Miller and Dr....

Dangerous New Carcinogens
2014-01-07 08:10:02

April Flowers for redOrbit.com - Your Universe Online New compounds produced by certain types of chemical reactions, such as those found in vehicle exhaust or grilling meat have been found by a research team at Oregon State University. Their findings, published in Environmental Science and Technology, reveal that these compounds are hundreds of times more mutagenic than their parent compounds, known as carcinogens. The previously unknown compounds raise concerns about the health impacts...

Panspermia -- Panspermia is a theory (more directly described as a hypothesis, as there is no compelling evidence yet available to support or contradict it) that suggests that the seeds of life are prevalent throughout the universe and life on Earth began by such seeds landing on Earth and propagating. The theory has origins in the ideas of Anaxagoras, a Greek philosopher. An important proponent of the theory was the British astronomer Sir Fred Hoyle. There is some evidence to...
