A highly detailed x-ray imaging technique previously been used to examine tumors in breast tissue and cartilage in knee and ankle joints could used for early diagnosis of Alzheimer’s disease. Researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory are the first to test the technique’s ability to visualize a class of minuscule plaques that are a hallmark feature of Alzheimer’s disease.

Scientists find marijuana reduces memory impairment

As difficult as some of our readers might find it to believe, researchers have found that specific elements of marijuana can be good for the aging brain by reducing inflammation and possibly even stimulating the formation of new brain cells. The research suggests that the development of a legal drug that contains certain properties similar to those in marijuana might help prevent or delay the onset of Alzheimer's disease. If you can’t wait for the drug to be developed, and don’t fancy coping with getting stoned every morning, Science Magazine has an interesting article about an alternative – dramatically reducing your calorific intake is also beneficial for memory.

New stem cell tools to accelerate drug development

U.K. Scientists have designed, developed and tested new molecular tools for stem cell research to direct the formation of certain tissue types for use in drug development programmes. A collaborative team of scientists from Durham University and the North East England Stem Cell Institute (NESCI) has developed two synthetic molecules which can be used to coax stem cells to ‘differentiate’ - that is, transform into other forms of tissue. Their use could also help reduce the number of animals used in laboratory research. Read More

NVIDIA’s new family of GeForce GTX 200 graphics processors (GPUs) - which includes the GeForce GTX 280 and GeForce GTX 260 GPUs - include NVIDIA CUDA technology and the new CUDA runtime for Windows Vista, which allows programmers to offload the most intensive processing tasks from the CPU to the NVIDIA GPUs. The GPUs also deliver 50% more gaming performance over the Company’s previous NVIDIA GeForce 8800 Ultra GPU with impressive shading horsepower at resolutions as high as 2560 x 1600. Read More

Alzheimer's detection using near-infrared light

It is estimated that around 4.5 million people in the US are currently living with Alzheimer's and the disease is one of the leading causes of death, accounting for tens of thousands each year. There has been no definitive way of diagnosing the disease on living patients so doctors have had to rely on medical histories, administering physical exams, and neuropsychological assessments. Now, a team of researchers in Massachusetts has developed a way of examining brain tissue with near-infrared light to detect signs of Alzheimer's disease. Read More

Researchers develop new dark field x-ray technique

February 5, 2008 A breakthrough by European researchers has the potential to expand the application of powerful "dark-field" x-ray imaging using standard medical and industrial imaging equipment. Normally only possible via prohibitively expensive and sophisticated crystal optics, the detailed images produced by "dark-field" x-rays could be applied to diagnose breast cancer or Alzheimer’s disease, identify explosives in hand luggage, or pinpoint hairline cracks in airplane wings.

Chemist Inventor 'Sniffs' His Way to Prestigious US$500,000 Lemelson-MIT Prize

By Kyle Sherer

April 3, 2007 Dr. Timothy M. Swager has a nose for explosives. The Massachusetts Institute of Technology Professor of Chemistry claims he can “almost always take a whiff of a chemical and make a pretty good guess as to what class a volatile compound might be in.” But Swager’s nose is nothing compared to the amplified chemical sensors he invented to detect vapors of common bomb-making chemicals, such as TNT. For his entire body of inventive work, the Lemelson-MIT Program named Swager the 2007 winner of the $500,000 Lemelson-MIT Prize, the most-prestigious cash prize for invention in the United States. This year, the prize criteria were modified to specify the winner be a mid-career inventor who is rising in his or her field. Read More

New 3D Imaging technology promises early detection of Alzheimer’s and Dementia

By Mike Hanlon

March 15, 2007 The older people become, the greater risk they have of sharing the tragic fate of those who remain alive yet are increasingly unaware of the world around them. In industrialised countries, one to six percent of the population over the age of 65 and an even more alarming ten to twenty percent over the age of 80 suffer a progressive loss of their cognitive abilities. Alzheimers disease is the most common cause, affecting 50 to 60 percent of all cases, followed by circulatory disorders in small blood vessels, capillaries and venules (calcifications), which make up about 20 percent. These disorders cause ever larger parts of the brain to become necrotic due to an insufficient supply of blood. Read More
