| Why can't the snakes cross the road, secret lives of baby snakes and other questions Posted: 02 Aug 2013 10:22 AM PDT Researchers are conducting some of the first ever scientific studies of neonate pine snakes, performing snake surgery for radio tracking and helping snakes survive road crossings through the busy New Jersey shore traffic. |
| Posted: 02 Aug 2013 10:22 AM PDT How is vital oxygen supplied to the tropical ocean? New research by oceanographers in Germany shows that about one third of the oxygen supply in these areas is provided by turbulent processes, such as eddies or internal waves. |
| How 'junk DNA' can control cell development Posted: 02 Aug 2013 07:19 AM PDT Researchers have confirmed that, far from being "junk," the 97 percent of human DNA that does not encode instructions for making proteins can play a significant role in controlling cell development. And in doing so, the researchers have unraveled a previously unknown mechanism for regulating the activity of genes, increasing our understanding of the way cells develop and opening the way to new possibilities for therapy. |
| Climate science boost with tropical aerosols profile Posted: 02 Aug 2013 06:51 AM PDT The seasonal influence of aerosols on Australia's tropical climate can now be included in climate models following completion of the first long-term study of fine smoke particles generated by burning of the savanna open woodland and grassland. |
| Baby owls sleep like baby humans: Owlets spend more time in REM sleep than adult owls Posted: 02 Aug 2013 06:48 AM PDT Baby birds have sleep patterns similar to baby mammals, and their sleep changes in the same way when growing up. This is what a biologists found out working with barn owls in the wild. The team also discovered that this change in sleep was strongly correlated with the expression of a gene involved in producing dark, melanic feather spots, a trait known to covary with behavioral and physiological traits in adult owls. These findings raise the intriguing possibility that sleep-related developmental processes in the brain contribute to the link between melanism and other traits observed in adult barn owls and other animals. |
| Study of gene expression has revealed first steps of evolution in gene regulation in mice Posted: 02 Aug 2013 05:02 AM PDT A study of gene expression has revealed the first steps of evolution in gene regulation in mice. The research has implications for the study of differences in gene regulation between people. |
| Pregnancy in horses: Helping horses come to term Posted: 02 Aug 2013 05:02 AM PDT It is not only humans that sometimes experience difficulty having children. Horses too have a low birth rate, with many pregnancies failing within the first few weeks after conception. The reason is currently unknown but recent research suggests that a particular class of blood cells may be involved. |
| Scientists uncover secrets of starfish’s bizarre feeding mechanism Posted: 01 Aug 2013 08:31 PM PDT Scientists have identified a molecule that enables starfish to carry out one of the most remarkable forms of feeding in the natural world. A starfish feeds by first extending its stomach out of its mouth and over the digestible parts of its prey, such as mussels and clams. The prey tissue is partially digested externally before the soup-like "chowder" produced is drawn back into its 10 digestive glands. |
