Mental and physical exercise delays dementia in fatal genetic disease
Scientists at Melbourne's Howard Florey Institute have discovered that mental and physical stimulation delays the onset of dementia in the fatal genetic disease, Huntington's disease. view more (2008-01-24)
Neuronal cell cultures kept on the straight and narrow
An improved technique for culturing cells, developed at the National Institute of Standards and Technology (NIST), may enable new, fundamental insights into the behavior of neuronal cells. view more (2006-05-26)
Research Shows How Visual Stimulation Turns Up Genes to Shape the Brain
Scientists have long known that brains need neural activity to mature and that sensory input is most important during a specific window of time called the "critical period" when the brain is primed for aggressive learning. view more (2006-05-08)
Researchers learn more about genetic mutation linked to autism
University of Iowa researchers have learned more about a genetic mutation that contributes to autism. The mutation occurred in sperm cells of a father, who does not have autism, but passed the condition on to two of his children. view more (2007-05-04)
Building memories with actin
Memories aren't made of actin filaments. But their assembly is crucial for long-term potentiation (LTP), an increase in synapse sensitivity that researchers think helps to lay down memories. view more (2009-07-13)
Prozac exposure found to disrupt mussel reproduction
Researchers from the National Institute of Standards and Technology (NIST) and North Carolina State University (NCSW) have demonstrated that a commonly prescribed antidepressant can interfere with the reproductive cycle of freshwater mussels-at least in a controlled setting. view more (2006-09-18)
Long-term changes in experience cause neurons to sprout new long-lasting connections
Howard Hughes Medical Institute researchers have discovered that neurons in the brains of mice sprout robust new connections when the animals are adjusting to new experiences. view more (2006-06-22)
Neuroscientists Show Insulin Receptor Signaling Regulates Structure and Function of Brain Circuits
A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has demonstrated for the first time in living animals that insulin receptors in the brain can initiate signaling that regulates both the structure and function of neural circuits. view more (2008-06-19)
Why you remember names and ski slopes
When you meet your boss's husband, Harvey, at the office holiday party, then bump into him an hour later over the onion dip, will you remember his name? view more (2007-11-26)
Stanford scientist's new findings of autism-associated synapse alterations lead to coveted NIH grant
A Stanford University School of Medicine researcher has pinpointed the mechanism by which a gene associated with both autism and schizophrenia influences behavior in mice. And just recently, he received a $1.65 million government grant to expand his efforts to include many more such genes. view more (2009-10-13)
Cold sore virus might play role in Alzheimer's disease
A gene known to be a major risk factor for Alzheimer's disease puts out the welcome mat for the virus that causes cold sores, allowing the virus to be more active in the brain compared to other forms of the gene. view more (2007-01-04)
Memory machine
What happens in our brains when we learn and remember" Are memories recorded in a stable physical change, like writing an inscription permanently on a clay tablet" Prof. Yadin Dudai, Head of the Weizmann Institute's Neurobiology Department, and his colleagues are challenging that view. view more (2007-08-17)
Protein can nurture or devastate brain cells, depending on its 'friends,' researchers find
Researchers at UT Southwestern Medical Center have uncovered new insights into the "Dr. Jekyll and Mr. Hyde" nature of a protein that stimulates stem-cell maturation in the brain but, paradoxically, can also lead to nerve-cell damage. view more (2008-11-12)
Search for blood pressure secrets reveals a surprising new syndrome
Yale researchers investigating the genetic causes of blood pressure variation have identified a previously undescribed syndrome associated with seizures, a lack of coordination, developmental delay and hearing loss. view more (2009-03-17)
The Unbearable Lightness of the Cube - at the new Barcelona Museum of Science
The new Barcelona Museum of Science opens its 50,000 square meters of exhibition space to the public on September 26th. One of the featured pieces in this impressive museum is the product of an unusual partnership between sculptor Etienne Kr'¤henbühl of Romainmôtier, Switzerland, and physicist Rolf Gotthardt of the Ecole Polytechnique... view more...

Exploring the function of sleep
Is sleep essential? Ask that question to a sleep-deprived new parent or a student who has just pulled an "all-nighter," and the answer will be a grouchy, "Of course!" view more (2008-08-26)
