MU maps course for improving pre-college science education

...simple: young people have a sense of direction and navigation that we wish to employ in helping them to understand how cells develop and how those cells navigate in three-dimensional space as tissues and how organizations are patterned during development. We are using this sense of direction, movement and geogr...

Fruit bats are not 'blind as a bat'

...hts, fruit bats cannot fly and stay hungry. Visual navigation at twilight and sometimes also during the daytime did not fit the older view that fruit bats only possess rods, the photoreceptors for night vision. This prompted Brigitte Mueller and Leo Peichl of the Max Planck Institute for Brain Research in Frank...

Essential in the interdisciplinary field of computational biology, computational proteomics applies the techniques of computer science, applied mathematics, and statistics to the large-scale study of proteins, p...

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 Universitys 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 ce...

New research shows sharks use their noses and bodies to locate smells

Prototype space probe prepares to explore Earth's deepest sinkhole

.... The team conducted initial tests of the probes navigation capabilities in February, successfully mapping La Pilita, the second deepest sinkhole in the Zacatn system. Operations during this first mission showed that DEPTHX could find its way through underwater space, collect samples in unexplored areas and ...

New research finds people and pigeons see eye to eye

...sion, Gibson has done extensive research involving navigation and memory in birds. He is currently investigating how the Clarks nutcracker uses different types of spatial information to return to hidden stores of food during winter.

The last wild hunt -- Deep-sea fisheries scrape bottom of the sea

...spawn make them particularly vulnerable. Satellite navigation (GPS) and military surveillance technology can visualize seamounts where schools of orange roughy, in times of former abundance, resembled lava spilling down the sides of a volcano. Orange roughy fishing began in New Zealand in the late 1970s. In ...

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 creat...

...may be epic in scale. These feats of endurance and navigation are widely regarded as some of the most astonishing of natures spectacles. Researchers have gained some important insights into the evolution of migration, yet very much remains unknown about the multiple mechanisms that animals call on when they mig...

Group decisions: From compromise to leadership in pigeon homing

...o better understand the basis of the paired birds' navigation choices, the researchers found that both forms of decision-making could emerge from just two simple forces acting simultaneously on the pigeons' behavior: "move toward your familiar route" and "move toward your partner." In cases of small disagreemen...

Biological clock of honey bee more similar to humans than to insects

... about 20 minutes. The clock is also essential for navigation that uses the sun as a compass because the sun moves during the day from east to west. Bees, whose bodies are slightly longer than one centimeter, precisely navigate to flowers situated as far as 10 km from their beehive. The central biological cl...

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 ...
