How Dangerous Are CT Scans?
Computed tomography (CT or CAT) scans help doctors detect everything from cancer to kidney stones. But some physicians are raising concerns about the safety of such procedures — most notably, an increase in cancer risk. ... Continue Reading
New advances in anti-aging revealed
Scientists in the US are working on a new anti-aging solution which combines two powerful ingredients, in a bid to create a cream that can increase the skin's ability to rejuvenate. ... Continue Reading
Sleep apnea associated with memory loss
Researchers in the US have made a groundbreaking discovery that links sleep apnea to memory loss. ... Continue Reading
Imaging Technique Is Highly Accurate In Diagnosing, Locating Pancreas Defects In Newborns
The noninvasive imaging technology called positron-emission tomography (PET scan) is extremely accurate in diagnosing a type of congenital hyperinsulinism, a rare but severe imbalance of insulin levels in newborns. When that disease is confined to a limited section of the baby's pancreas, the PET scan is 100 percent accurate in locating the abnormal spot, and guiding surgeons to curative, organ-sparing surgery. ...

New Microscope Reveals Deadly Secret Life Of Malaria Parasites Inside Human Cells
Scientists at Georgetown University are describing the first use of a new microscope technology to capture images of live malaria parasites inside human red blood cells. They say the advance could be important in efforts to understand the malaria parasite's deadly tendency to become resistant to anti-malaria drugs and in developing new drugs and vaccines for the disease. ...

Brain Images Show Hysteria Not An Imaginary Disorder
In what's being called a novel finding, researchers using brain scans have uncovered evidence of cerebral dysfunction in women with sensory conversion disorder, better known as hysteria. The study's findings open up a new window to understanding hysteria, an unexplained neurological disorder in which a patient complains of symptoms, but doctors can't find anything medically wrong with them. The study is published in the December 12, 2006, issue of Neurology, the scientific journal of the American Academy of Neurology. ... Continue Reading
New Imaging Technique Discovers Differences In Brains Of People With Autism
Using a new form of brain imaging known as diffusion tensor imaging (DTI), researchers in the Center for Cognitive Brain Imaging at Carnegie Mellon University have discovered that the so-called white matter in the brains of people with autism has lower structural integrity than in the brains of normal individuals. This provides further evidence that the anatomical differences characterizing the brains of people with autism are related to the way those brains process information. ... Continue Reading
Scientists Capture Nanoscale Images With Short And Intense X-ray Laser
Lawrence Livermore National Laboratory scientists for the first time have validated the idea of using extremely short and intense X-ray pulses to capture images of objects such as proteins before the X-rays destroy the sample. At the same time, the team also established a speed record of 25 femtoseconds for flash imaging. ... Continue Reading
