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...

Institute of Transformative Bio-Molecules (ITbM), Nagoya University Researchers at ITbM, Nagoya University developed a new nickel catalyst with a "Kabuto-like" structure that was found to catalyze the cross-coupling reaction between carbonyl compounds and readily available phenol derivatives, to form alpha-arylketones, which are found in many biologically active compounds (Kabuto = a helmet worn by Japanese samurai). Professors Kenichiro Itami and Junichiro Yamaguchi of the Institute...

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....

Decreased exposure to air pollution associated with increases in key protein in brain development Decreased exposure to air pollution in utero is linked with improved childhood developmental scores and higher levels of brain-derived neurotrophic factor (BDNF), a key protein for brain development, according to a study looking at the closure of a coal-burning power plant in China led by researchers at the Columbia Center for Children's Environmental Health at the Mailman School of Public...

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...

Combination of physical and psychosocial stressors during fetal development magnifies the effect of each exposure Maternal psychological distress combined with exposure to air pollution during pregnancy have an adverse impact on the child's behavioral development, according to researchers at the Columbia Center for Children's Environmental Health at the Mailman School of Public Health. The study, which appears in the journal Pediatrics, reports that maternal demoralization, a measure of...

Determining The Role Of Chemicals Found In Secondhand Smoke
2013-06-26 10:03:21

April Flowers for redOrbit.com - Your Universe Online Scientists have known for a while that tobacco smoke, diesel exhaust and oil combustion are sources of polycyclic aromatic hydrocarbons (PAHs) that are known to cause cancer. The vast majority of research attention has been paid to the obviously dangerous high-molecular-weight PAHs like benzo[a]pyrene (BaP). The low-molecular-weight variety have been overlooked for the most part, with previous studies showing that these compounds alone...

Cassini Spacecraft Observes Aerosol 'Snow' On Saturn Moon Titan
2013-06-05 14:44:00

Lee Rannals for redOrbit.com — Your Universe Online Scientists writing in The Astrophysical Journal say they have found aerosol "snow" on Saturn's moon Titan. The scientists said they confirmed the presence of Polycyclic Aromatic Hydrocarbons (PAHs) in the upper atmosphere of Saturn's largest moon. This study provides an explanation of the origin of the aerosol particles found in the lowest haze layer that blankets Titan's surface. Titan has an atmosphere most resembling that...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
