A Nebula by Any Other Name

Posted on by

Nebulae are enormous clouds of dust and gas occupying the space between the stars. Some have pretty names to match their good looks, for example the Rose nebula, while others have much more utilitarian names. Such is the case with LBN 114.55+00.22, seen here in an image from NASA's Wide-field Infrared Survey Explorer, or WISE.

Named after the astronomer who published a catalogue of nebulae in 1965, LBN stands for "Lynds Bright nebula." The numbers 114.55+00.22 refer to nebula's coordinates in our Milky Way galaxy, serving as a sort of galactic home address.

Astronomers classify LBN 114.55+00.22 as an emission nebula. Unlike a reflection nebula, which reflects light from nearby stars, an emission nebula emits light. Emission nebulae are usually found in the disks of spiral galaxies, and are places where new stars are forming.

The colors used in this image represent specific wavelengths of infrared light. Blue and cyan represent light emitted at wavelengths of 3.4 and 4.6 microns, which is predominantly from stars. Green and red represent light from 12 and 22 microns, respectively, which is mostly emitted by dust.

CMS to Rescind Physician Signature Requirement; CMS’ Change in Policy Illustrates the Power of Grassroots Advocacy

Posted on by

The American Society for Clinical Pathology (ASCP) is pleased to announce that it has learned that the Centers for Medicare and Medicaid Services (CMS) is planning to rescind its recent rule requiring a physician's signature on requisitions for laboratory tests reimbursed under the Medicare clinical laboratory fee schedule. The CMS rule proved very controversial and prompted not only the collective opposition of the entire laboratory coalition but also the American Medical Association and a number of other medical specialty societies.

ASCP, in tandem with its partners in the Clinical Laboratory Coalition, mounted an aggressive campaign to protest the proposal. ASCP launched two separate advocacy campaigns on the rule. The first campaign let CMS know directly the concerns of ASCP members, while the second campaign was intended to encourage members of Congress to contact CMS in opposition to the rule. In total, ASCP members wrote more than 2,000 letters in opposition to the rule. CMS received a loud and clear message from Congress today as the agency received a letter from 89 members of the U.S. House of Representatives and another letter from more than 30 U.S. Senators.

In announcing the agency's intent to withdraw the rule, it was mentioned that the agency would officially withdraw the rule well in advance of the April 1 date that the rule was supposed to go into effect. For more information on the rule, click here.
