NASA - National Aeronautics and Space AdministrationHouston, TX – On Earth, research into antibody-drug conjugates to treat cancer has been around a while. The research presents a problem, though, because Earth-based laboratories aren’t able to mimic the shape of the cancer cell within the body, which can sometimes produce incorrect findings.

The International Space Station’s unique microgravity environment allows scientists to approach the research from a new, 3-D angle.

NASA scientists use new Technique to examine meteor, comet materials for components of Life

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – While the origin of life remains mysterious, scientists are finding more and more evidence that material created in space and delivered to Earth by comet and meteor impacts could have given a boost to the start of life.

Some meteorites supply molecules that can be used as building blocks to make certain kinds of larger molecules that are critical for life.

Researchers have analyzed carbon-rich meteorites (carbonaceous chondrites) and found amino acids, which are used to make proteins.

Written by David Vergun

U.S. ArmyWashington, D.C. – Working out or losing weight often tops the list for New Year’s resolutions — with varying degrees of success experienced by those who do.

Those resolutions can be achieved painlessly, and, people don’t have to wait until 2014 to get started, according to a family medicine doctor at Madigan Army Medical Center in Joint Base Lewis-McChord, or JBLM, Wash.

Dr. (Col.) John O’Brien, who is also chief of Operational Medicine, is convinced he knows what he’s talking about because he said it worked for him.

Dr. (Col.) John O'Brien poses for a photo a few months ago with his wife Karen and son Thomas, who is 11. Karen is now serving as a surgeon in Kabul, Afghanistan.

Written by Dr. Dale Brown

Marathon ChiropracticClarksville TN – A University of Rhode Island study funded by the National Institutes of Health (NIH), found the weight loss drug Orlistat, which goes by the prescription brand name Xenical and the over-the-counter name Alli, can cause “severe toxicity” to major internal organs.
