Sea Urchins Reveal Medical Mysteries
Researchers are using the
sea urchins to study and
understand diseases like
cancer, Alzheimer's disease,
Parkinson's disease and
muscular dystrophy. Although
they are invertebrates, the

Learning to Walk Again
In a method called deep
brain stimulation, certain
movement disorders are
treated by implanting wires
in the brain that deliver
electrical signals. The
surgical procedure can last
up to eight hours, during
... > full story
Pinpointing Problems In The Brain
Doctors are now using a new
kind of brain scan called
magnetoencephalography
(MEG), which measures brain
activity in real time. In
some cases, MEG can pinpoint
the source of an epileptic

Diagnosing Alzheimer's Early
A new brain-imaging method
allows physicians to
diagnose Alzheimer's before
its onset. A radioactive dye
is injected in the blood and
travels to the brain, where
it attaches to plaque

Optical Scientists, Psychiatrists Develop Minimally Invasive Eye Test for Alzheimer's
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 ... > more -
Physicists' Invention Opens Access to Computers for Persons with Tremors
For $100, people with tremors could finally be able to use a computer mouse. A new mouse adapter filters out the high-frequency, shaky component of the movement, transmitting only the steady ... > more -
MRIs Peek into the Brains of Synesthesia Patients
Cognitive neuroscientists have now documented hundreds of cases of synesthesia -- the condition in which one sense triggers the response of a different one. Using functional magnetic resonance ... > more -
Molecular Biologists Devise Strategy To Starve Brain Tumors
Brain tumor researchers have found that brain tumors arise from cancer stem cells living within tiny protective areas formed by blood vessels in the brain. Killing those cells is a promising ... > more -
Interventional Neuroradiologists Treat Brain Strokes with New Kind of Stent
A new "wingspan" stent helps restore blood flow for patients with intracranial atherosclerotic disease, or ICAD. Surgeons insert the stent up the leg arteries, guide it to the brain, then let its ... > more -
Psychiatrists Can Predict Onset of Alzheimer's with New EEG Test
Using new computer software that analyzes EEG data, psychiatrists can now better distinguish early signs of Alzheimer's from normal aging, by spotting marked differences between the left and right ... > more -
Neuroendocrinologists Unlock Chemical Trigger to Puberty
Researchers have discovered the precise chemical chain reaction that could be the much-sought-after puberty trigger: The KiSS-1 gene, which produces a protein in the hypothalamus, a part of the ... > more -
Neurosurgeon Devises MRI-Based Technique to Diagnose Sciatica
Up to 40 million American suffer from sciatica pains, but the condition is often not diagnosed correctly. A new imaging technique uses a specially tuned MRI scan to image nerves and highlight them ... > more -
Psychobiologists Find Genetic Component in Children's Food Preference
In the first study to link taste genes to behavior in children, researchers looked at how natural variations in a recently discovered taste gene affected sensitivity to bitter tastes and food ... > more -
Exhibit Delves into Science of Taste and Smell
An exhibit at San Francisco's Exploratorium explains the science of cooking and eating, and in particular how we taste food. Our sense of taste comes from a combination of smell receptors in the nose ... > more
