| Posted: 16 May 2012 04:54 PM PDT In 1848, Phineas Gage survived an accident that drove an iron rod through his head. Researchers, for the first time, used images of Gage's skull combined with modern-day brain images to suggest there was extensive damage to the white matter "pathways" that connected various regions of his brain. |
| Listening to chickens could improve poultry production Posted: 16 May 2012 12:22 PM PDT Listening to squawks and other chicken "vocalizations" using digital signal processing techniques may help farmers better manage growing conditions, contributing to both healthier birds and more productive poultry operations. |
| Posted: 16 May 2012 11:00 AM PDT Researchers have transplanted a set of human genes into a zebrafish and then used it to identify genes responsible for head size at birth. This finding also is related to some cases of autism and possibly schizophrenia and childhood obesity. |
| People with paralysis control robotic arms to reach and grasp using brain computer interface Posted: 16 May 2012 11:00 AM PDT Two people with tetraplegia were able to reach for and grasp objects in three-dimensional space with robotic arms that they controlled directly with brain activity. They used the BrainGate neural interface system, an investigational device currently being studied under an IDE. One participant used the system to serve herself coffee for the first time since becoming paralyzed nearly 15 years ago. |
| Posted: 16 May 2012 08:58 AM PDT After seeing faces for less than a blink of an eye, college students have accuracy greater than mere chance in judging others' sexual orientation. Their "gaydar" persisted even when they saw the photos upside-down, and gay versus straight judgments were more accurate for women's faces than for men's. |
| Chocolate and diamonds: Why volcanoes could be 'a girl's best friend' Posted: 16 May 2012 06:32 AM PDT Scientists have discovered a previously unrecognized volcanic process, similar to one that is used in chocolate manufacturing, which gives important new insights into the dynamics of volcanic eruptions. The scientists investigated how a process called 'fluidized spray granulation' can occur during kimberlite eruptions to produce well-rounded particles containing fragments from the Earth's mantle, most notably diamonds. |
