Science Tonight!

 The Orionid Meteor Shower


Peak morning is October 21.  The moon is in waxing crescent phase, so with clear skies, you should be able to view tonight as well.

Each year the Earth passes through the stream of debris left by Comet Halley, the parent comet of the Orionids.  They're not the strongest shower, or the brightest, but they do leave persistent trains - ionized gas trails that last for a seconds after the meteor is gone.

Orion ascends in the east after midnight, and though the meteors radiate from nearby, they radiate in all directions, and become visible about 30 degrees out from their radiant point, so they will be seen all over the sky.  

The meteors strike our atmosphere going about 41 miles per second, vaporizing some 60 miles above Earth's surface.


Enjoy your viewing!

  Science is also serious. You may have heard that a case review is ongoing regarding the safety and science of an abortion pill, called mifepristone, that has been on the market since 2000.

Of course, the FDA already vetted the drug and numerous studies show the pill is safe and effective. "If courts can go against a whole tremendous amount of scientific evidence, that just doesn't seem right." More Info: Science News News and Politics

  Othram is a company providing forensics technology for cold case work. "Justice is not a luxury; it is a basic human right." In 1997, rock climbers in rural Washoe County found human remains buried under stones in a shallow grave.  While cause of death could not be determined, it was ruled a homicide. Investigators entered her information, including a forensic facial reconstruction, into the National Missing and Unidentified Persons System but no leads yielded a match. Earlier this week, with Othram's help, Washoe County was able to identify Lorena Gayle Mosley, who was 41 at the time of her death.   Scientists were able to develop a DNA extract to be used in genome sequencing, building a comprehensive profile for the victim.  Their in-house genetic genealogy team was then able to develop investigative leads that were returned to Washoe County. In follow-up investigation, the Medical Examiner's Office Medicolegal Death Investigator/Technician Supervisor Sarah Turne
