| Young apes manage emotions like humans do Posted: 14 Oct 2013 12:57 PM PDT Researchers studying young bonobos in an African sanctuary have discovered striking similarities between the emotional development of the bonobos and that of children, suggesting these great apes regulate their emotions in a human-like way. This is important to human evolutionary history because it shows the socio-emotional framework commonly applied to children works equally well for apes. |
| Stepping out in style: Toward an artificial leg with a natural gait Posted: 14 Oct 2013 12:57 PM PDT Humans rarely walk the straight and narrow; something's always in the way. So scientists are developing a computer-controlled artificial limb that can turn like a flesh-and-blood foot. |
| From football to flies: Lessons about traumatic brain injury Posted: 14 Oct 2013 12:56 PM PDT Faced with news of suicides and brain damage in former professional football players, geneticists have bemoaned the lack of model systems for studying the insidious and often delayed consequences linked to head injuries. |
| A blueprint for restoring touch with a prosthetic hand Posted: 14 Oct 2013 12:56 PM PDT New research is laying the groundwork for touch-sensitive prosthetic limbs that one day could convey real-time sensory information to amputees via a direct interface with the brain. |
| Birth gets the brain ready to sense the world Posted: 14 Oct 2013 09:17 AM PDT Neurons that process sensory information are arranged in precise, well-characterized maps that are crucial for translating perception into understanding. A study reveals that the actual act of birth in mice causes a reduction in a brain chemical called serotonin in the newborn mice, triggering sensory maps to form. The findings shed light on the role of a dramatic environmental event in the development of neural circuits and reveal that birth prepares newborns for survival. |
| Adult stem cells help build human blood vessels in engineered tissues Posted: 14 Oct 2013 08:37 AM PDT Researchers have identified a protein expressed by human bone marrow stem cells that guides and stimulates the formation of blood vessels. Their findings could help improve the vascularization of engineered tissues. |
| Go to bed: Irregular bedtimes linked to behavioral problems in children Posted: 14 Oct 2013 06:38 AM PDT Researchers have found that children with irregular bedtimes are more likely to have behavioral difficulties. The study found that irregular bedtimes could disrupt natural body rhythms and cause sleep deprivation, undermining brain maturation and the ability to regulate certain behaviors. |
| Database of disease genes shows potential drug therapies Posted: 13 Oct 2013 01:33 PM PDT Researchers have created a massive online database that matches thousands of genes linked to cancer and other diseases with drugs that target those genes. Some of the drugs are approved by the U.S. Food and Drug Administration, while others are in clinical trials or just entering the drug development pipeline. |
