Dual-imaging technique useful before -- and during -- brain surgery

... Leach and his colleagues use a high-tech surgical navigation system known as BrainLAB. The BrainLAB technology incorporates functional MRI data to identify brain areas linked to speech, movement and vision, and diffusion tensor imaging data to map critical “white-matter tracts”—the electrical connections betwe...

NASA-funded robotic sub finds bottom of world's deepest sinkhole

... inner dimensions. The vehicle employed autonomous navigation and mapping systems developed by Carnegie Mellon University’s Robotics Institute. During a two-week NASA-funded exploration led by Bill Stone of Stone Aerospace, the Deep Phreatic Thermal Explorer (DEPTHX) revealed that the geothermal sinkhole, or c...

Is there a pilot in the insect?

...ined these results by modeling the overland flight navigation of insects using experiments carried out on OCTAVE, a captive flying robot microhelicopter that can reproduce much of the mysterious natural insect behavior. Their work is published online in Current Biology, February 8, 2007. How does a tiny creatu...

Three-dimensional, miniature endoscope opens new diagnostic possibilities

...e device's size and flexibility should allow safer navigation through such delicate structures as the salivary ducts, the fallopian tubes and the pancreatic duct. Fetal and pediatric procedures may also benefit from this tool. Eventually, SEE could give rise to new procedures that permit diagnosis and microsur...

Coming soon: 3-D imaging that flies 'through' and 'around' cancer

...us tumors--from inside the body--provides a visual navigation of organs oftentimes portrayed on television crime shows like "CSI." Such visualization "may be used to detect and characterize cancer, spare someone from more invasive medical procedures, lead to better disease detection rates of colon cancer, provi...

Beekeepers work hard for the honey, despite changing tupelo forest

... years of dredging of the Apalachicola for a river navigation project. The dumping of the dredged material has cut off many tupelo trees from their source of fresh water. Upstream water diversion also has lessened the flooding needed for a healthy tupelo forest. Exotic pests are taking their toll, and beekeep...

Septum keeps neurons in synch, can reduce epileptic seizures by 90 percent

... of the brain that plays a role in memory, spatial navigation and sensory motor integration, among other functions. Normally, the hippocampus oscillates at a frequency of 3-12 Hz, a frequency that is called the theta rhythm, Colom explained. Oscillations at theta frequency are important in processing and stor...

Bumble bees can estimate time intervals

... the passage of time, and insect communication and navigation may also require the ability to estimate the duration of time intervals. In the new work, the researchers investigated bumble bees' ability to time the interval between successive nectar rewards. Using a specially designed chamber in which bumble ...

Bats use touch receptors on wings to fly, catch prey, study finds

...y that bats use their sense of touch for nighttime navigation and hunting. The theory that bats fly by feel was first proposed in the 1780s by French biologist Georges Cuvier, but faded in the 1930s when researchers discovered echolocation, a kind of biological sonar found in bats, dolphins and a few other ani...

Virtual microscopy project wins educational technology award

The researchers' techniques include molecular analysis of butterfly brain prote...

Chickadees can help humans get their bearings

...rly in life, we could broaden and hone our spatial navigation abilities," said Dr. Sturdy and Dr. Marcia Spetch, who supervised the work conducted by graduate students Emily Gray and Laurie Bloomfield. The findings also suggest the need for more research outside of lab environments, Dr. Sturdy said. "We have t...

Researchers discover underwater volcano

Such hazards may include the explosive reaction between red-hot lava and seawater, or tsunamis that may be caused by the collapse of the newly built volcano. "It is a good idea for us to keep our eyes on this area, but there...

South America's vast pantanal wetland may become next everglades, UNU experts warn
