Some experts have argued that the rising rates are merely a result of expanded screening, which catches small tumors that otherwise might go undetected.

The work also confirms that Kenyans with HIV/AIDS suffer depression at as high or higher a rate than those with HIV/AIDS in developed countries. http://www.physorg.com/news154721830.html Medicine & Health Tue, 24 Feb 2009 18:17:39 EST news154721830 (PhysOrg.com) -- Gestures serve an important role in language learning and development, and differ depending upon the language and culture, notes a Georgia State University researcher who is investigating how children born blind use gestures as part of language development in the United States and Turkey. http://www.physorg.com/news154360199.html Medicine & Health Fri, 20 Feb 2009 13:50:38 EST news154360199 (PhysOrg.com) -- A study of college freshmen in the United States and in China found that Chinese students know more science facts than their American counterparts -- but both groups are nearly identical when it comes to their ability to do scientific reasoning. http://www.physorg.com/news152461628.html Other Sciences Thu, 29 Jan 2009 14:27:29 EST news152461628 The first study documenting methicillin-resistant Staphylococcus aureus (MRSA) in swine and swine workers in the United States has been published by University of Iowa researchers. http://www.physorg.com/news151913729.html Medicine & Health Fri, 23 Jan 2009 06:16:39 EST news151913729 What if free exercise classes were offered in public spaces such as parks, beaches and recreation centers?

Late preterm births, or births that occur between 34 and 36 weeks (approximately 4 to 6 weeks before the mother's due date), account for more than 70% of preterm births. Despite the large number of affected babies, many people are unaware of the serious health problems related to late preterm births. A new study and an accompanying editorial soon to be published in The Journal of Pediatrics investigate the serious neurological problems associated with late preterm births. http://www.physorg.com/news148192562.html Medicine & Health Thu, 11 Dec 2008 04:36:02 EST news148192562 The United States must re-establish its global leadership in nuclear arms control while continuing to update its nuclear arsenal as necessary, but it should not add any new nuclear capabilities in the process, a joint working group of scientists and policy experts says in a study meant to inform decision making by the incoming Obama administration. http://www.physorg.com/news148132530.html Other Sciences Wed, 10 Dec 2008 11:55:30 EST news148132530 The economic cost of death due to cancer is high in the United States, regardless of whether researchers estimate the economic impact in lost work productivity or in a more global measure using the value of one year of life, according to two studies published online December 9 in the Journal of the National Cancer Institute. http://www.physorg.com/news148067483.html Medicine & Health Tue, 09 Dec 2008 17:51:23 EST news148067483 When it comes to the world of the very, very small - nanotechnology - Americans have a big problem: Nano and its capacity to alter the fundamentals of nature, it seems, are failing the moral litmus test of religion. http://www.physorg.com/news147881829.html Nanotechnology Sun, 07 Dec 2008 14:17:09 EST news147881829 Organizations in the United States that are at the highest risk of sustaining damage from climate change are not adapting enough to the dangers posed by rising temperatures, according to a Yale report. http://www.physorg.com/news147444502.html Space & Earth Tue, 02 Dec 2008 12:48:22 EST news147444502 Tufts researchers and colleagues report that place of birth plays a role in the occurrence of asthma in a United States black population.
