Womb needed for proper brain development

... developing during pregnancy in utero, very little patterned sensory stimulation reaches the brain, she explained. The eyelids are closed, the infant is bathed in fluid and minimal sounds are perceived. In contrast, once the premature infant is born, he is necessarily bombarded by a complex environment full o...

Cuttlefish masters of disguise despite colorblindness

...'s behavioral response to a series of checkerboard patterned substrates of various colors and brightnesses. They found that the animals did not respond to the checkerboard pattern when placed on substrates whose color intensities were matched to the Sepia visual system, suggesting that these checkerboards app...

Polymers show promise for lab-on-a-chip technology

...hin film on a glass backing, can be fabricated and patterned on a microscale. The research was published recently in the Journal of Material Chemistry. "Based on our research of liquid crystalline polymers, we anticipate the emergence of exciting new techniques in microfabrication that can be used to cheaply ...

Neuronal cell cultures kept on the straight and narrow

...hannels can be used to lay down the PEM coating in patterned lines just a few micrometers wide. Neuronal cells will largely confine themselves to the pattern, enabling a variety of cell-geometry experiments, such as measuring the maximum gap between lines that can be bridged by neural axons and dendrites. The...

First surveys of Tanzanian mountains reveal 160+ animal species, including new & endemic

...under the forest canopy. The smooth-skinned, brown patterned frog measures about 2.25 inches from snout to bottom. "Surveying just one section of the Eastern Arc, we discovered a little frog no one knew existed," said Nike Doggart, lead author of the article and Technical Advisor, Tanzania Forest Conservation...

Snakes' virtual glasses, leopard spots and all-optical transistors

...beam and a control beam. When the beams strike the patterned film they produce plasmons, which are essentially blobs of electron gas near the surface of a metal. Varying the intensity and the color of the control beam causes the plasmons to interact in ways that enhance or decrease the transmission of the sign...

How ants find their way

... only able to search in the predicted place when a patterned background was introduced as a retrieval cue. Prof... "To know which cylinder was which ants needed the patterned background to be in a different position on the retina when they faced one or other cylinder. Accura...

UCLA/Toronto researchers unlock key to memory storage in brain

...t had visited before. The cage was outfitted with patterned walls and a unique smell. To visualize which brain cells stored the mouse's memories about the cage, the scientists tracked a genetic marker that reveals recent neuron activity. When the team examined the animals' amygdalas after the experiment...

Applied scientists create wrinkled 'skin' on polymers

...at exploring the behavior of living cells on these patterned substrates. Such research may lead to the development of an effective and robust method to build custom templates for engineering and growing tissues. "We are approaching this field of research from various directions," says Vaziri. "At the moment ...

Magnetic computer sensors may help study biomolecules

...alves, each about one by four micrometers in size, patterned on a 200-nanometer-thick silicon nitride membrane in fluid. When the spin valves are turned on, a local magnetic field is created that is strongest near the ends of the magnetic stack below the membrane—a field strong enough to trap nanoscale magneti...
