Two Telescopes Combine To Probe Young 'Family'Of Stars
A spectacular new image from NASA's Spitzer Space Telescope uncovers a small group of young stellar "siblings"in the southern portion of the Serpens cloud -- located approximately 848 light-years away from Earth. Scientists suspect that this discovery will lead them to more clues about how these cosmic families, which contain hundreds of gravitationally bound stars, form and interact. Penn Researchers Provide Recommendations For Artificial Nutrition And
For two decades, doctors have followed an ethically-established agreement about the appropriate use of artificial nutrition and hydration (ANH) for patients who are seriously ill or in a persistent vegetative state. The Terri Schiavo case -- which included very open, dramatic disagreements among family members over such considerations -- publicly challenged long-held agreements about ANH and caused many to question its proper use. In response to such challenges, researchers from the University of Pennsylvania's Institute on Aging and Center for Bioethics, and the Philadelphia VA's Center for Health Equity Research and Promotion review and clarify ethical principles regarding the use of ANH. Space Debris: Assessing The Risk
Assessing the risk that space debris pose to operational spacecraft and satellites is a challenge and depends on whether you are worried about being hit by a known, tracked debris object or by an unknown object. At least the known objects are, well, known. These include old spacecraft, other satellites, rocket bodies and large fragments from past break-ups. Statins Reduce The Risk Of Stroke And Death After Carotid Artery Surge
Carotid artery endarterectomy (CEA) is the most commonly performed operation to prevent stroke in the United States. However, the operation itself carries a small risk of stroke. Statin drugs provide protection against stroke and death for patients undergoing CEA when given during the week prior to surgery, according to a new study to be published in the November issue of the Journal of Vascular Surgery. Everyday Text Shows That Old Persian Was Probably More Commonly Used T
For the first time, a text has been found in Old Persian language that shows the written language in use for practical recording and not only for royal display.

While obesity has been shown to contribute to high blood pressure, heart disease and diabetes, being overweight in old age does not lead to memory problems, according to a new study. Snappy New Pear Is Long-Storing, Blight-Resistant
Shenandoah, the third fire blight-resistant pear developed by Agricultural Research Service horticulturist Richard Bell, has recently been released. The luscious new pear will appeal to consumers who enjoy rich-tasting fruit, because its higher-than-average acidity gives it a snappy flavor. Shenandoah's relatively high acidity is balanced with a high level ofsugars that makes it sweet. Study Identifies Gene In Mice That May Control Risk-taking Behavior In
Scientists at Fred Hutchinson Cancer Research Center have found that a specific neurodevelopmental gene, called neuroD2, is related to the development of an almond-shaped area of the brain called the amygdala, the brain's emotional seat. Adapter Lets Any Car Use Ethanol
