Cerebral navigation: How do nerve fibers know what direction to grow in?
Nervous system development requires billions of neurons to migrate to the appropriate locations in the brain and grow nerve fibers (axons) that connect to other nerve cells in an intricate network. Growth cones, structures in the tips of growing axons, are responsible for steering axons in the right direction, guided by a complex set of signals from cells they encounter along the way. Some signal...Navigating the brain for sense of direction as paradigm for higher cognitive functions
No matter how healthy a life one leads, no person has managed to live much longer than a century. Even though the advances of the modern age may have extended the average human life span, it is clear there are genetic limits to longevity. One prominent theory of aging lays the blame on the accumulation of damage done to DNA and proteins by “free radicals,?highly reactive molecules produced by the...Protein's role in regulating cell death sets direction for cancer research
A protein called calpain can be the key either preventing or promoting the cell death, a Queen's University study has found. "This work provides proof in principle that pharmacological inhibition of calpain may be used to block cell death in situations where this is not desirable, such as in neuronal cells of Alzheimer's or Parkinson's patients, but to promote cell death in cancer cells w...pLenti6/V5 Directional TOPO Cloning Kit from Invitrogen

I spent the morning with Milwaukee entrepreneurs at eForum 2005, where one of the hot topics was the shift from selling services to selling products. The thinking was that it's easier to grow per-employee revenue selling products. Later that day, IBM announced that its year over year earnings were doing...Users help software company morph in new directions

A new ray of hope in AIDS research. A new set of anti-viral compounds has proved much more potent than the original in laboratory studies and opened a promising new direction in AIDS research. These related developments are described in the current tissue.

According to a US study insomnia or loss of sleep affects finding way around negatively. It has an impact on route and navigation and there is difficulty finding the way around.// This was tried and tested on rats. When sleep was tampered with rats' spatial memory was affected. Still, experts at UK were not convinced and divided over the findings published in the Journa...Research In A New Direction To Develop Innovative Psychotropic Drugs
The American College of Neuropsychopharmacology held its annual meeting at Nashville on 4 th December. At the meeting ,leading brain and behavior researchers called for// the need to move in a new direction to develop innovative psychotropic drugs to treat mental illness. The panel consisted of representatives from academics, industry and government. They held several factors respon...Chickens also Use Earth's Magnetic Field to Sense Direction
A new research by a Frankfurt University team has successfully demonstrated that domestic fowl, like many other animals and birds, also use the Earth's magnetic field to sense direction . As part of their experiment, the team of Prof. Dr. Wolfgang Wiltschko and Roswitha Wiltschko placed newly hatched chicks in an artificial magnetic field, teaching them by intensive training that th...3.5v StrabismoScope Unidirectional Occluder
