How Plants Benefit From Forest Fires
2013-04-30 11:18:53

Brett Smith for redOrbit.com - Your Universe Online Forest fires are a major cause of plant death and destruction, but they can also be a source of life as some dormant seeds begin to germinate in the aftermath of a raging inferno. Previous research has shown chemicals in the smoke of burning trees called karrikins“¯are responsible for this phoenix-like rebirth. Now, a new study in the Proceedings of the National Academy of Sciences has described new details on the mechanism...

DNA Study Reveals Secrets Of Gentically Similar Polar And Brown Bears
2013-03-15 10:22:25

Brett Smith for redOrbit.com - Your Universe Online A new report in PLoS Genetics attempts to clarify conflicting studies on a population of Alaskan brown bears that are genetically similar to polar bears, yet look and act like typical brown bears. "This population of brown bears stood out as being really weird genetically, and there's been a long controversy about their relationship to polar bears," said co-author Beth Shapiro, a professor of ecology and evolutionary biology at the...

Project 1640 Imaging System Allows Astronomers To See Distant Exoplanets
2013-03-13 21:39:14

Brett Smith for redOrbit.com — Your Universe Online Using a state-of-the-art telescopic imaging system, astronomers are now able to see planets that orbit distant stars, known as exoplanets, more easily and in greater detail, according to a report in the Astrophysical Journal. Scientists gather information from distant planets via the light they radiate, referred to as their spectra, and previously, astronomers have only been able to analyze planets as they pass in front of, or...

April Flowers for redOrbit.com - Your Universe Online Disregard of three critical protocols, including sorting samples by size, explains why a group challenging the theory of a North American meteor-impact event approximately 12,900 years ago failed to find iron and silica rich magnetic particles in the sites they investigated, says a new study from an interdisciplinary team of scientists. Edward K. Vogel, co-author of the study published in the online Early Edition of Proceedings of...

Tagish Lake Meteorites Help Solve Amino Acid Mysteries
2012-07-26 14:48:28

Lee Rannals for redOrbit.com - Your Universe Online New clues have been unveiled that shed light on why living things use only molecules with specific orientations. Research analyzing meteorite fragments that fell on a frozen lake in Canada is providing strong evidence that liquid water inside an asteroid leads to a preference of left-handed over right-handed forms of common protein amino acids in meteorites. "Our analysis of the amino acids in meteorite fragments from Tagish Lake...
