| Posted: 06 Oct 2013 05:42 PM PDT A unique study of 16 pairs of identical twins in which one twin is obese and the other lean has yielded some surprising results. In 8 of the pairs of twins, the obese twin was as 'metabolically healthy' as his or her lean co-twin, while in the other 8 pairs, the obese twin had a poorer blood fat profile, higher liver fat and increased insulin production and resistance, and higher blood pressure -- all hallmarks of unhealthy obesity.  |
| What evolved first, a dexterous hand or an agile foot? Posted: 06 Oct 2013 05:41 PM PDT Resolving a long-standing mystery in human evolution, new research indicates that early hominids developed finger dexterity and tool use ability before the development of bipedal locomotion.  |
| First-ever view of gene activity, transcript patterns in single human cells Posted: 06 Oct 2013 01:13 PM PDT Biologists have developed a method to visualize the activity of genes in single cells. The method is so efficient that, for the first time, a thousand genes can be studied in parallel in ten thousand single human cells. Applications lie in fields of basic research and medical diagnostics. The new method shows that the activity of genes, and the spatial organization of the resulting transcript molecules, strongly vary between single cells.  |
| How binge drinking impairs healing of broken bones Posted: 06 Oct 2013 01:13 PM PDT Physicians have long observed that binge drinking impairs healing of broken bones. A new study is providing insights into how alcohol slows healing on the cellular and molecular levels. The findings could lead to better treatments to improve bone healing.  |
| Salt-tolerant bacteria improve crop yields Posted: 06 Oct 2013 11:27 AM PDT Microbiologists hope to apply a new agricultural technique soon to boost the yield of economically important crops such as wheat, cotton, tomato and cucumber.  |
| Association between adolescents' anxiety, depressive symptoms Posted: 06 Oct 2013 11:27 AM PDT A large-scale study conducted on the family life, physical and emotional health of high school students has shed light on an association between adolescent anxiety and depressive symptoms.  |
| Posted: 06 Oct 2013 11:24 AM PDT Scientists have discovered huge ice channels beneath a floating ice shelf in Antarctica. At 250 meters high, the channels are almost as tall as the Eiffel tower and stretch hundreds of kilometers along the ice shelf. The channels are likely to influence the stability of the ice shelf and their discovery will help researchers understand how the ice will respond to changing environmental conditions.  |
