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...

Brake For Spinning Molecules
2014-03-13 15:39:05

Max Planck Institute The precise control of the rotational temperature of molecular ions opens up new possibilities for laboratory-based astrochemistry Chemical reactions taking place in outer space can now be more easily studied on Earth. An international team of researchers from the University of Aarhus in Denmark and the Max Planck Institute for Nuclear Physics in Heidelberg, discovered an efficient and versatile way of braking the rotation of molecular ions. The spinning speed of...

Astronomers Discover Drastic Chemical Change In The Birth Of A Planetary System
2014-02-14 04:33:39

Lee Rannals for redOrbit.com - Your Universe Online A team of scientists led by the University of Tokyo say that the chemical compositions of an interstellar cloud and the disk are not identical. Stars are formed by the contraction of interstellar gas and dust, and this mix ends up helping to eventually form planets. However, scientists have wondered whether the chemical compositions of the interstellar cloud and the disk that creates the planets are identical. The latest findings,...

New Techniques Tease Out Building Blocks Of Life In Meteorites
2014-02-04 06:24:52

[ 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...

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...

Supernova Dust Factory
2014-01-06 12:08:48

[ Watch the Video: Supernovas May Be Galactic Dust Factories ] Lee Rannals for redOrbit.com - Your Universe Online A new image of a recent supernova could offer up insight to scientists about how galaxies became so dusty. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have observed the remains of supernova 1987A located in the Large Magellanic Cloud about 168,000 light-years from Earth. This is the closest observed supernova explosion since Johannes...

Earthen Crust Oxygen Got Its Start During Creation Of Solar System
2013-10-25 07:03:56

April Flowers for redOrbit.com - Your Universe Online A long standing mystery in the formation of the Solar System has been solved by cosmochemists from the University of California, San Diego (UCSD). In the oldest, most pristine rocks, oxygen, the most abundant element in the Earth's crust, follows a strange, anomalous pattern that must result from a different chemical process than the well-understood reactions that form minerals containing oxygen on Earth. "Whatever the source of...

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...

Critical Interplay Discovered Between Cosmic Dust, Magnetic Fields
2013-09-27 10:40:02

Brett Smith for redOrbit.com - Your Universe Online Interstellar magnetic fields can be found throughout the Milky Way and other similar galaxies. They are thought to be a key regulator in star formation and the propagation of cosmic rays. A new study published in The Astrophysical Journal has provided new insights for scientists looking to probe the strength and structure of these magnetic fields, a highly difficult phenomenon to accurately measure. To learn more about interstellar...

Molecular Cloud -- Molecular clouds are interstellar nebulae that have a density and size sufficient to permit the formation of H2, molecular hydrogen. However, this molecule is difficult to detect, and the molecule most used to trace the H2 is CO (carbon monoxide). The ratio between CO luminosity and H2 mass is roughly constant, although there are reasons to doubt this assumption in observations of some other galaxies. In the Milky Way, molecular clouds account for roughly one-half...

Interstellar Cloud -- Interstellar cloud is the generic name given to accumulations of gas and dust in our galaxy. Depending on the density, size and temperature of a given cloud, the hydrogen in it can be neutral (HI clouds) or molecular (molecular clouds). Chemical compositions Analysing the composition of interstellar clouds is achieved by studying electromagnetic radiation that we receive from them. Large radio telescopes scan the intensity in the sky of particular frequencies of...
