Ecologists work to link kids with nature

...nd land-use management, says Lowman. Kids need to touch flowers and know why some plants cant survive without pollinators such as bees. It also doesnt hurt to know the difference between a harmless king snake and a venomous coral snake! Richard Louv notes in his book that children growing up over the l...

Bright future for nano-sized light source

...ays been that you can look at an object or you can touch it, said Liphardt. With our nanowire light source technology, we combine both these capabilities in a single device. This opens up the possibility of being able to manipulate a specimen as you visualize it. Central to the success of the nanowire li...

Gut check: Tracking the ecosystem within us

... -- the birth canal, mothers' breast, and even the touch of a sibling or parent. Within days, a thriving microbial community is established and by adulthood, the human body typically has as many as ten times more microbial cells than human cells. This is primarily due to the large number of microorganisms ...

Cancer drug enhances long-term memory

...hat humans can get when they walk across a rug and touch a door knob. Afterward, scientists injected HDAC inhibitors into the brains of mice, targeting the hippocampus, a region involved in short-term and long-term memory. A day later, the scientists returned the mice to the chamber to see how well they re...

But just how young neurons make their presence known and hook up with already well-connected elders has been unclear. "If you have hopes that one day neuronal stem cells can replace damaged neurons in neurodegenerati...

A matter of force

... grow until they reach the borders of the cell and touch the cortex. Upon contact with the cortex, the filaments immediately start to shrink. "This shrinkage is then translated into a pulling force at the cortex," says Cleopatra Kozlowski from Ndlec's group, who carried out the research together with Mar...

Deflecting damage: Flexible electronics aid brain injury research

...could be coated with electronic "skin" that senses touch and temperature and sends that information back to the brain like any natural human limb. "A basic problem with the interface between electronics and living tissue is that electronics are hard and tissues are soft," he said, noting that nerve cell...

MIT device draws cells close -- but not too close -- together

...o express specific liver functions, they needed to touch supporting stromal cells for 18 hours. For the liver cells to survive and continue to act as liver cells, they don't have to keep touching these stromal cells, but they do need to stay close. The finding will allow Bhatia and Hui to examine more d...

Super-thin membrane, 50 atoms thick, sorts individual molecules

...anes, meaning the two groups of cells can actually touch each other through the membrane's pores without passing through themselves. The chemical communication between the helper and stem cells can continue as if the two sets of cells were in direct contact, but after the neurons are fully formed, they can...

Low-pathogenic forms of bird flu do cause illness among birds

...ecause of their slower migration, ill birds get in touch with many more healthy birds passing by them on migration. In this way the virus can spread itself more rapidly than previously thought."
