Orion nebula

Observing infrared wavelengths of light, researchers have detected certain molecules which are pre-cursors to life as we know it. Such findings happen from time to time, this time in Orion’s nebula.

By sifting through the pattern of spikes in Orion nebula’s light signature, or spectrum, astronomers have identified a few common molecules that are precursors to life-enabling molecules, including water, carbon monoxide, formaldehyde, methanol, dimethyl ether, hydrogen cyanide, sulfur oxide and sulfur dioxide. Each spike in the spectrum corresponds to a particular molecule.

“This HIFI spectrum, and the many more to come, will provide a virtual treasure trove of information regarding the overall chemical inventory and on how organics form in a region of active star formation. It harbors the promise of a deep understanding of the chemistry of space once we have the full spectral surveys available,” said Edwin Bergin of the University of Michigan and the principal investigator of the HEXOS Key Program on Herschel.

A win for vaccines

A court has ruled again against vaccine-autism claims.

The special U.S. Court of Federal Claims ruled that vaccines could not have caused the autism of an Oregon boy, William Mead, ending his family’s quest for reimbursement.

“The Meads believe that thimerosal-containing vaccines caused William’s regressive autism. As explained below, the undersigned finds that the Meads have not presented a scientifically sound theory,” Special Master George Hastings, a former tax claims expert at the Department of Justice, wrote in his ruling.

In February 2009, the court ruled against three families who claimed vaccines caused their children’s autism, saying they had been “misled by physicians who are guilty, in my view, of gross medical misjudgment”.
