Buy ACUVUE 2 » Detecting Alzheimer's Early28th October 2009 (sciencedaily.com) Building upon a recent discovery that the same Alzheimer's disease process that goes on in the brain also occurs in the eye, researchers have developed a pair of optical tests that can determine the presence of amyloid beta proteins -- found in all Alzheimer's patients -- in the lens of the eye. A device called an interior laser ophthalmoscope can pick up the presence of the amyloid protein.

The always churning minds over at Fraunhofer-Gesellschaft are already on the issue, recently conjuring up a new material designed to "efficiently dissipate heat even in devices with densely packed components and that can give increasingly miniaturized electronics a longer life." Researchers at the entity's Institute for Manufacturing Engineering and Applied Materials Research have teamed with gurus from Siemens and Plansee to create the substance as part of the EU project "ExtreMat." Unfortunately, details beyond that are few and far between, but given that demonstrations have reportedly "already been produced," we'd say it's well on its way to infiltrating things far smaller than your mind can grasp. Read Article on New cooling material keeps heat down in densely packed electronics» The five ages of the brain: Gestation3 April 2009 (newscientist.com) By the time we take our first breath, the brain is already more than eight months old. It starts to develop within four weeks of conception, when one of three layers of cells in the embryo rolls up to form the neural tube. A week later the top of this tube bends over, creating the basic structure of fore, mid and hindbrain. From this point, brain growth and differentiation is controlled mainly by the genes. Even so, the key to getting the best out of your brain at this stage is to have the best prenatal environment possible. In the early weeks of development, that means having a mother who is stress-free, eats well and stays away from cigarettes, alcohol and other toxins. Towards the end of the brain-building process, when the fetus becomes able to hear and remember (see "The five ages of the brain: 2 Childhood"), sounds and sensations also begin to shape the brain.

Neuroscientist Vilayanur S. Ramachandran worked with patients who had so-called phantom limbs, including Tom, a man who had lost one of his arms. Ramachandran discovered that if he stroked Tom’s face, Tom felt like his missing fingers were also being touched. Each part of the body is represented by a different region of the somatosensory cortex, and, as it happens, the region for the hand is adjacent to the region for the face. The neuroscientist deduced that a remarkable change had taken place in Tom’s somatosensory cortex. Read Article on Six Ways to Boost Brainpower» |

Aging Eyes – Robbing Your Vision
A scientific doctor with the National Institutes of Health says that America will spend between $20 and $22 million dollars on eye problems and that one American becomes blind or has severe vision loss every 11 minutes. Being aware of common age-related eye problems and knowing the warning signs of eye health concerns associated with age can curb the debilitating effects of eye problems.
Take Care Of Your Eyes
If you find any discomfort of your eyes, see your eye doctor as soon as possible, or serious problems may be caused.
vision
In humans, the image of an object created by each of our eyes is slightly different because our eyes are in different positions. The brain combines the two images to give a sense of depth. This is known as binocular vision. With one eye closed we lose some of our sense of depth and perspective.
A person who is short-sighted (suffers from myopia) can see clearly objects that are close, but cannot create a sharp image of objects that are far away. The light from distant objects is being focused in front of the retina. This defect can be correct using diverging lenses.
