Research, published in BioMed Central's open access journal Genome Biology, shows that Mexicans mate according to proportions of Native American to European ancestry, while Puerto Ricans are more likely to settle down with someone carrying a similar mix of African and European genes. http://www.physorg.com/news177917997.html Biology Fri, 20 Nov 2009 05:40:44 EST news177917997 (PhysOrg.com) -- Scientists in Australia have identified a single gene that strongly influences whether you have curly or straight hair. http://www.physorg.com/news177063334.html Medicine & Health Tue, 10 Nov 2009 08:16:43 EST news177063334 (PhysOrg.com) -- Becoming "hard of hearing" is a standard but unfortunate part of aging: A syndrome called age-related hearing loss affects about 40 percent of people over 65 in the United States, and will afflict an estimated 28 million Americans by 2030. http://www.physorg.com/news177007147.html Medicine & Health Mon, 09 Nov 2009 17:30:11 EST news177007147 (PhysOrg.com) -- Spend a little time people-watching at the beach and you're bound to notice differences in the amount, thickness and color of people's body hair.
