Maize is an important crop in many countries of the world. It is widely used for human consumption, animal feed, and industrial materials. It also is considered an exemplar plant species for studying domestication, molecular evolution, and genome architecture. http://www.physorg.com/news177863490.html Biology Thu, 19 Nov 2009 14:33:54 EST news177863490 Penguins that died 44,000 years ago in Antarctica have provided extraordinary frozen DNA samples that challenge the accuracy of traditional genetic aging measurements, and suggest those approaches have been routinely underestimating the age of many specimens by 200 to 600 percent. http://www.physorg.com/news177083943.html Biology Tue, 10 Nov 2009 13:59:42 EST news177083943 Humans and chimpanzees are genetically very similar, yet it is not difficult to identify the many ways in which we are clearly distinct from chimps. In a study published online in Genome Research, scientists have made a crucial discovery of genes that have evolved in humans after branching off from other primates, opening new possibilities for understanding what makes us uniquely human. http://www.physorg.com/news171051139.html Medicine & Health Tue, 01 Sep 2009 19:13:05 EST news171051139 The first ever genetic linkage map for a non-avian member of the Class Reptilia has been developed. Researchers writing in the open access journal BMC Genomics have constructed a first-generation genetic linkage map for the saltwater crocodile Crocodylus porosus. http://www.physorg.com/news168030445.html Biology Tue, 28 Jul 2009 21:40:01 EST news168030445 Once thought to be only the realm of the blue-ringed octopus, researchers have now shown that all octopuses and cuttlefish, and some squid are venomous. The work indicates that they all share a common, ancient venomous ancestor and highlights new avenues for drug discovery. http://www.physorg.com/news159014369.html Biology Wed, 15 Apr 2009 11:40:03 EST news159014369 Yale researchers have harnessed the power of 21st century computing to confirm an idea first proposed in 1916 - that plants with rapid reproductive cycles evolve faster. Their findings appear in the October 3rd edition of Science. http://www.physorg.com/news142173413.html Biology Thu, 02 Oct 2008 13:36:53 EST news142173413
