How does a mountain range maintain its youthful, rugged appearance after 200 million years without tectonic activity? Try a geological facelift – courtesy of the earth's mantle. http://phys.org/news278781550.html Space & Earth Wed, 30 Jan 2013 15:19:23 EST news278781550 We all know the feeling, the short, sharp shock of waking to the sound of an alarm clock. Whether the traditional clattering metal bells, the incessant beeping of digital or the dulcet tones of today's radio news reader. Even the chance to slap the snooze button to grab a few extra moments between the sheets does not leave everyone feeling refreshed when they finally crawl out of bed. Now, researchers in India think they have the answer. http://phys.org/news238324115.html Technology Thu, 20 Oct 2011 10:08:48 EST news238324115 Do examples of rejuvenation exist in nature? Yes, during reproduction! For the first time, a team from the Laboratoire de Biologie Moleculaire de la Cellule at CNRS (France) has managed to visualize, in the model organism C. elegans, the sudden "rejuvenation" of oocytes just before fertilization. Published in the journal Aging Cell, this work opens new avenues for understanding ageing and the diseases that are associated with it. http://phys.org/news209642795.html Medicine & Health Mon, 22 Nov 2010 10:07:09 EST news209642795 Researchers at the National Institute on Aging (NIA), part of the National Institutes of Health, have discovered a key to embryonic stem (ES) cell rejuvenation in a gene -- Zscan4 -- as reported in the March 24, 2010, online issue of Nature. This breakthrough finding could have major implications for aging research, stem cell biology, regenerative medicine and cancer biology. http://phys.org/news188657237.html Biology Wed, 24 Mar 2010 14:00:18 EST news188657237 Microdermabrasion using a coarse diamond-studded instrument appears to induce molecular changes in the skin of older adults that mimic the way skin is remodeled during the wound healing process, according to a report in the October issue of Archives of Dermatology, one of the JAMA/Archives journals. http://phys.org/news175191788.html Medicine & Health Mon, 19 Oct 2009 18:40:09 EST news175191788 Researchers from Boston University School of Medicine (BUSM) and the Laser and Skin Cancer Center of Indiana, (Carmel, Indiana), found that there has been a dramatic increase in the number of procedures performed and patient demand for dermatologic health care since 2000. The findings, which were recently reported in Dermatologic Surgery, parallels the growth in the age of individuals between the ages of 40 to 55, who make up the "Baby Boomer" generation. http://phys.org/news173968864.html Medicine & Health Mon, 05 Oct 2009 14:00:11 EST news173968864
